FIELD OF THE INVENTION

The invention relates to a frame comprising one or more internal channels, as well as frame elements and connecting elements of said frame. The frame elements are in particular suitable to construct a temporary room divider for asbestos removal and to construct a living environment.

BACKGROUND OF THE INVENTION

In various areas of the construction industry, working environments may have a number of requirements such as presence of electrical power, access to pressurized air and enclosure from the surroundings. Further, materials need to be supplied to and removed from the working environment. Materials that need to be supplied to the working environment include tools, building materials, and cleaning materials. Materials that need to be removed from the working environment include debris and waste, which may comprise biohazards, requiring specific handling procedures.

Generally, each of these requirements is fulfilled by a dedicated system, such as power cables for electrical power, pressure hoses for pressurized air and containment structures for enclosure. Besides cluttering the workspace inside the working environment, the different systems often place further requirements on each other. As an example, the requirement for enclosing the working environment from the surroundings, for example for abating harmful dust emissions when removing asbestos, complicates supply of materials to and removal of materials from the working environment.

Removal of asbestos is often performed inside buildings such as residential buildings or commercial buildings. During the removal operations, harmful asbestos dust may be released. In order to prevent this dust from contaminating the building, the working environment wherein the removal operations are performed is enclosed by a temporary enclosure. Such enclosures are tailor made for each work site, because the size and shape of each work site may be unique. After the operations are completed, the enclosure is taken down. Building and taking down the enclosure is at present a highly labour, time and cost intensive job. When removing asbestos, double airlocks are presently used to pass material and personnel to and from the enclosure surrounding the working environment, and all material and personnel that has entered the enclosure needs to be thoroughly cleaned. This is cumbersome and time-intensive.

Enclosed working spaces where the air is contaminated, for example by harmful suspended dust such as asbestos or chrome-6 containing dust, are often kept at a pressure that is slightly lower than atmospheric pressure, such that no contaminated air may leak out of the enclosure. This is generally achieved by actively removing air from the enclosure at a small number of suction points. Because only a small number of suction points is used, a large flow of air towards these suction points may occur. Further, the concentration of contaminants in the air may vary throughout the enclosure as a result of the spatial distribution of the suction points, which may lead to locally elevated concentrations of contaminants within the enclosure.

Living environments generally require supply and removal of various media such as supply of fresh water, electrical power, clean air and warmth and removal of waste water such as sewage and dirty air. In present building techniques for living environments, each of those requirements is fulfilled by a dedicated system of pipes, wires, tubes and the like. This leads to a complicated building process demanding large amounts of skilled labour.

DE7209638 discloses a telescopic construction support, comprising an outer pipe 12 and an inner pipe 11 , both of which are hollow. The pipes are movable in a longitudinal direction with respect to each other and fixable in this direction using bolts 13 that fit through holes 112,

114, 124, 126 in the side walls 121 , 122 of the outer pipe 12 and the inner pipe 11 .

DE202008003789 discloses a device for closing off environments against dust, in particular for use in asbestos removal operations. The device comprises supports which are telescopically adjustable in length. Closing of the environment is achieved by attaching chipboard or plasterboard to a frame constructed from vertical supports 1a and horizontal members 4b. The vertical supports are different from the horizontal supports.

DETAILED DESCRIPTION OF THE FIGURES

In figure 1 , a longitudinally extendable frame element 10 is shown in a non-extended state. The frame element 10 comprises a first end part 22, a first intermediate part 28, a central part 24, a second intermediate part 30, and a second end part 26, without space in between them in the non-extended state. The cross-section of the frame element spans a generally square shape.

The frame element comprises five internal longitudinal channels 12 which extend through the full length of the frame element. One of the internal longitudinal channels 12 is a central internal longitudinal channel 80, which has a larger diameter than the peripheral internal longitudinal channels 82. The central internal longitudinal channel 80 is a gas channel.

The frame element 10 comprises venting means 48 which bring the central internal longitudinal channel 80 in fluid communication with the environment. The venting means 48 form a passage through an outer wall 54 of the frame element 10 and are arranged on both the first end part 22 and the second end part 26.

The frame element 10 comprises two longitudinal construction slits 76 on each of the faces of the frame element 10. The venting means 48 are arranged between the longitudinal construction slits 76.

Figure 2 shows a frame element 10 in an extended state, as well as a connection device 90. The frame element 10 is extendable in a longitudinal direction over an extension range by moving the first end part 22, the central part 24 and the second end part 26 in a longitudinal direction 14 with respect to each other. The internal longitudinal channels 12 extend from the first end of the frame element 18 to the second end of the frame element 20 under all extension conditions within the extension range.

The frame element comprises ratcheting means 84 for regulating the length of the frame element 10. The ratcheting means comprise a rack 86, which is connected to the central part 24, and a pawl 88 in each of the first end part 22 and the second end part 26. The first intermediate part 28 and the second intermediate part 30 comprise pawls 88 to regulate their position along the longitudinal direction of the frame element 14. The pawls 88 are operated by ratcheting operating means 89.

The central part 24 of the frame element 10 comprises a frame socket 62 on each of the four sides of the frame element 10. The frame sockets 62 provide access to the internal longitudinal channels 12. The frame sockets 62 may be closed by a closing plug 109. Alternatively, a connecting plug 108 may be connected to a frame socket 62 such that another frame element 10 or another device may be connected to the frame element 10. Figure 3A shows a detail view of figure 2, showing the central part 24 of the frame element 10. A connecting plug 108 is shown which provides access to only the central internal longitudinal channel 80, not to the peripheral internal longitudinal channels 82. A closing plug 109 is shown to close off the frame socket 62 when it is not in use.

Figure 3B shows a detail view of a connecting device 90. The connecting device 90 is configured to interconnect frame elements 10 such that the internal longitudinal channels 12 of each frame element 10 are connected to the corresponding internal longitudinal 12 channels of any connected frame element 10. The connecting device comprises a channel routing block 92 that comprises block channels 98 with an entrance to each of the block channels 102 on each of the block faces 100.

The block channels 98 have an inner dimension that is substantially equal to the inner dimension 42 of the outer channel tubes 40 of the frame elements 10 and to the outer dimension 38 of the inner channel tubes 36. The block channels connect the internal longitudinal channels of connected frame elements to the corresponding internal longitudinal channels of any connected frame element.

A connecting plug 108 comprises connecting channel tubes 110 that have an outer dimension which is substantially the same as the inner dimension 42 of the outer channel tubes 40 of the frame elements 10 and as the outer dimension 38 of the inner channel tubes 36. The outer dimension of the connecting channel tubes 110 is thus such that they fit within both the outer channel tubes 40 and the block channels 98.

Figure 4 shows a cross-section of a frame element 10 at a position along either the first end part 22 or the second end part 24. The frame element 10 comprises an outer frame beam 66 and an inner frame beam 68. Both frame beams have a generally square cross-section. The outer frame beam 66 comprises magnetic members 70 at the four outer corners. These magnetic members allow ease of attachment of various objects to the outer surface of the frame element 10.

The frame element 10 comprises three secondary frame channels 74 arranged between the inner frame beam 68 and the outer frame beam 66. The secondary frame channels 74 are enclosed on one side by an outer side of the inner frame beam 68 and on three sides by an inner side of the outer frame beam 66. The secondary frame channels 74 are part of an internal lumen 56 and extend in a longitudinal direction 14 of the frame element 10. Figure 5 shows a cutaway section of the first end part 22. The internal lumen 56 is in fluid communication with the environment via the venting means 48 and in fluid communication with the interior of the central internal longitudinal channel 80 via openings 58 in the outer internal longitudinal channel tube. In the imaged embodiment, the central internal longitudinal channel 80 is a gas channel, such that gas may be supplied to the environment or gas that may contain impurities may be removed from the environment. The internal lumen in arranged in both the first end part 22 and the second end part 26 and extends in a longitudinal direction 14 of the frame element. A ratchet cover plate 132 seals off the ratchet from the internal lumen 56.

Figure 6A shows the routing of the block channels 98 inside the channel routing block 92. The block channels 98 have a constant cross-section along their length. The block channels 98 have an inner dimension that is substantially equal to an inner dimension 42 of the outer channel tube 40 of the frame elements 10.

The block channel entrances 102 on each of the faces 100 of the channel routing block are arranged in either a first layout or a second layout. The second layout is a mirror image of the first layout. The block channel entrances 102 are arranged in the second layout on a block face 100 that is opposite to a block face where the block channel entrances 102 are arranged in the first layout. The first layout corresponds with the layout of the internal longitudinal channels on the first end of the frame element 18, such that a frame element 10 may be connected with its first end 18 to the channel routing block 92 at a block face 100. The second layout corresponds with the layout of the internal longitudinal channels on the second end of the frame element 20, such that a frame element 10 may be connected with its second end 18 to the channel routing block 92 at a block face 100. This ensures that frame elements 10 can be connected to each other such that they are in line with each other or such that they are at perpendicular angles with each other, while it is ensured that the correct connections are made between each of the internal longitudinal channels 12.

The channel routing block 92 is cube shaped. The block channel entrances 102 are arranged in the first layout on three of the block faces 100 and in the second layout on three of the block faces 100.

A reference block channel 99 extends between a first reference block channel entrance 991 A on a first block face 1003 and a second reference block channel entrance 991 B on a second block face. The second block face is opposite to the first block face 1003. The reference block channel 99 shown in figure 6A comprises bends, but may alternatively pass substantially straight through the channel routing block 92, as shown in e.g. figure 6B.

A further block channel 992 extends between a first further block channel entrance 993A on a third block face 1005 and a second further block channel entrance 993B on a fourth block face. The third block face 993A is opposite to the fourth block face. A block channel connection 994 is arranged in the channel routing block 92 to connect the reference block channel 99 to the further block channel 992.

Figure 6B shows the routing of the block channels 98 inside an alternative embodiment of a channel routing block 92. The block channels 98 are straight. The block channel entrances 102 are arranged along a straight layout line 103 on each of the block faces 100. The straight layout line 103 is a diagonal of the block face 100.

The block channel entrances 102 on each of the faces 100 of the channel routing block 92 are arranged in a common layout 101 . The common layout 101 is oriented in either a first orientation 104 or a second orientation 105. The first orientation 104 is rotated over a layout rotation angle with respect to the second orientation 105 around an axis 106 perpendicular to a plane 107 of the common layout 101 , wherein the common layout 101 is oriented in the second orientation 105 on a block face 100 that is opposite to a block face 100 where the common layout 101 is oriented in the first orientation 104. The layout rotation angle is approximately 90 degrees. The channel routing block 92 has six block faces 100. The channel routing block 92 is generally cube-shaped, in particular a rectangular cuboid, more in particular a cube, wherein the common layout 101 is oriented in the first orientation 104 on three of the block faces 100 and the common layout 101 is oriented in the second orientation 105 on three of the block faces 100. The common layout 101 in the second orientation 105 is a mirror image of the common layout 101 in the first orientation 104. The block faces 100 are generally polygonal in shape, in particular generally rectangular in shape, more in particular generally square in shape. The block faces 100 have four sides which define a square.

The position of any block channel entrance 102 on any block face 100 may be given by two orthogonal coordinates 1001 , 1002 in said block face 100, wherein each block channel entrance 102 on a given block face 100 has a different value in both said orthogonal coordinates 1001 , 1002 than each other block channel entrance 102 on said block face 100.

The common layout 101 is line symmetric with respect to a first symmetry axis 1031 which divides the common layout 101 into a first half 1011 of the common layout 101 and a second half 1012 of the common layout 101 , wherein the first half 1011 of the common layout 101 is a mirror image of the second half 1012 of the common layout 101 when mirrored in the first symmetry axis 1031 . In figure 6B, the first symmetry axis 1031 coincides with the common layout line 103.

Figures 7 A and 7B show alternative layouts of the internal longitudinal channels 12. In figure 7A, five channels of similar size are used instead of a large central internal longitudinal channel 80 and smaller peripheral internal longitudinal channels 82. In figure 7B, four peripheral internal longitudinal channels 82 of similar size are used.

The inner channel tube 36 has an outer dimension 38 such that it fits within the outer channel tube 40. Thus, the outer dimension 38 of the inner channel tube 36 is the same or slightly smaller than the inner dimension 42 of the outer channel tube 40. This allows the inner channel tube 36 and the outer channel tube 40 to slidably move in a longitudinal direction 14 with respect to each other. The outer channel tube 40 is formed by a hollow cutout in the inner frame beam 68.

The inner channel tubes 36 are formed by first channel elements 32 which are connected to the central part 24 of the frame element 10. In both the first end part 22 and the second end part 26, second channel elements 34 form the outer channel tube 40. The first channel elements 32 and the second channel elements 34 together form the internal longitudinal channels 12. First second channel elements 34 are arranged in the first end part 22 and second second channel elements 34 are arranged in the second end part 26. The first channel elements 32 extend through the central part 24 and protrude in opposite directions from the central part 24 along a longitudinal direction 14 of the frame part 10. The first channel elements 32 extend into the first end part 22 and the second end part 20, such that a section of the inner channel tubes 36 is inserted into the outer channel tubes 40. The inner channel tubes 36 and the outer channel tubes 40 together form telescopic internal longitudinal channel tubes. The first second channel elements 34 slide over the first channel elements 32 when the first end part 22 is moved in the longitudinal direction 14 with respect to the central part 24 and the second second channel elements 32 slide over the first channel elements 32 when the second end part 26 is moved in the longitudinal direction 14 with respect to the central part 24. The section of the inner channel tube that is inserted in the outer channel tubes decreases when the frame element is lengthened and increases when the frame element is shortened. The inner channel tubes 36 pass through the intermediate parts 28, 30. The intermediate parts 28, 30 can be moved in the longitudinal direction 14, wherein their movement is limited by the first end part 22, the central part 24 and the second end part 26. At the location where the inner channel tube 36 enters the outer channel tube 40, the interior of the channel is sealed off from the environment by a sealing plate 46.

The internal longitudinal channels 12 may transport fluids and may be pressurized to a pressure that is different from the atmospheric pressure. In the imaged embodiment, the central internal longitudinal channel 80 is an air channel. This air channel may be pressurized by an external device to a pressure that is lower than the ambient pressure, such that air is sucked into the venting means 48, through the internal lumen 56 and the holes 56 in the outer channel tube 40 into the gas channel. This way, contaminated air may be removed from an environment such as a workspace, for example a workspace for removing asbestos of paint containing chrome-6, where air with suspended dust is to be removed from the working environment to prevent leaks of harmful material to the environment. The contaminated air can then be processed by an external device to filter out the impurities.

The internal longitudinal channels 12 may also be used for removing liquid or solid waste from an environment. Solid waste may be shredded by a shredding device before it is transported through an internal longitudinal channel 12. Other devices 124 that may be connected to a frame element 10 may be tools such as drills, vacuum cleaning heads or spray heads. These tools may receive electrical power, data, signals and/or pressurized media from the internal longitudinal channels 12 within the frame element 10. These devices should comprise at least one internal device channel that is connectable to the internal longitudinal channels 12 via a connecting device, which is connectable to a frame socket 62.

Figures 8A and 8B show an electronic channel 59. The first channel element 32 comprises first channel element electrodes 60 and the second channel element 34 comprises second channel element electrodes 61 . The first channel element electrodes 60 and the second channel element electrodes 61 form pairs which are in sliding contact with each other if the frame element 10 is extended in the longitudinal direction 14. The electrodes maintain electrical contact irrespective of the length of the frame element due to the sliding electrical contact. The electronic channel in the image is configured for transporting three phase current. Different numbers of electrode pairs may be used to transport data and/or electronic signals or other types of electrical power.

Figure 9 shows a section of a frame 114 comprising multiple vertical frame elements 116, multiple horizontal frame elements 118 and multiple wall elements 120, of which only one is drawn. The frame encloses a working environment 122. Figures 10 and 11 show detail views of this frame. Figures 12A and 12B show how a wall element 120 is connected to a frame element 10. Slit fasteners 126 are used to secure the wall element 120 to a longitudinal construction slit 76. The magnetic members 70 help to attach the wall element, in which a magnetically attractable element 127 is incorporated.

Figure 13 shows an embodiment of a wall element 120 comprising cover plates 128. The cover plates ensure that an environment 122 can be sealed off under all extension conditions of the frame element by connecting a wall element 120 to each of the first end part 22, the central part 24 and the second end part 26. The wall element connected to the central part 24 is a central wall element 138. It is overlapped by the other two wall elements (the upper and lower wall elements 134, 136) to a degree that varies with the extension state of the frame element 10. Figure 14 shows this schematically. The solid lines 1341 indicate the edges of the upper wall element 134, the solid lines 1361 indicate the edges of the lower wall element 136 while the dashed lines indicate the edges 1381 of the central wall element 138. The cover plates 128 have accommodation passages 130 to accommodate the frame socket 62, the venting means 48, and the block faces 100.

Figure 15A shows a perspective image of an embodiment of a channel routing block 92 comprising coaxial block channels 98, comprising an inner channel 981 and an outer channel 982. The inner channel 981 is supported in the outer channel 982 by channel supports 983. The channel supports 983 may be perforated or truncated in order to allow fluid passage through the outer channel 982 from one block channel entrance 102 to another block channel entrance 102. The inner channel 981 and the outer channel 982 are separated from each other by an intermediate channel wall 984.

Figure 15B shows a top view image of the channel routing block 92 of figure 15A. Figure 15C shows a cross-section of the channel routing block of figure 15A along the line A - A in Figure B. Figure 15D shows a cross-section of the channel routing block of figure 15A along the line B - B in figure B. Figure 15E shows a cross-section of the channel routing block 92 of figure 15A along the line C - C in figure B. In figures 15D and 15E, the intermediate channel wall 984 of the block channel 98 coming out of the page is also shown, even though this would strictly not be visible on a cross-section. This intermediate channel wall 984 is shown nevertheless for clarity purposes, to indicate that it is a 6-way junction.

The frame elements 10 may also comprise coaxial internal longitudinal channels 12, such that said frame elements 10 may be connected to a channel routing block 92 comprising corresponding coaxial block channels 98. Coaxial channels allow for a compact construction. Using only one set of coaxial channels, arranged in the centre of the block face 100 and in the centre of the frame element 10 ensures full rotational symmetry of the layout 101 or the block channel entrances 102 on the block faces 100. This allows use of a single connector that may furthermore be connected at any orientation around a block channel axis 106.

Figure 16A shows a cross-section of a part of an assembled frame 114 comprising three frame elements 10 and a connecting device 90. The frame elements 10 comprise frame valves 140 comprising a valve spring 142 and a valve core 144. Frame valves 140 are arranged at the first end 18 of the frame element 10 and/or the second end 20 of the frame element 10. Figure 16B shows a cross-section of a part of a partially disassembled frame 114 comprising frame valves 140. In a disassembled state, the frame valves 140 seal the internal longitudinal channels 12 as the valve core 144 is pushed into the core stop 148 by the valve spring 142. The O-ring 146 ensures a fluid tight seal. In assembled state, fluid flow through the frame valve 140 is allowed as the valve spring 142 is compressed. Compression of the valve spring 142 is achieved by a valve actuator 150. Alternatively, the frame 114 may comprise block valves, which function similarly to the frame valves but which are integrated in the connecting device 90. As a further alternative, the valves 140 may be separate from both the frame element 10 and the connecting device 90.

Connecting members 202 connected to the connecting device 90 engage with connecting member receivers 204 arranged in the frame elements 10 in order to align the connecting devices 90 and the frame elements 10 and to connect them in a rigid manner. The connecting members 202 and connecting member receivers 204 may comprise locking means, as shown in figures 19E and 19F.

Use of valves 140 prevents leakage from or into any end of an internal longitudinal channel 12 or of a block channel 98 that is not connected.

Figure 17 shows a portion of a frame 114 comprising multiple frame elements 10 and a connecting device 90. The frame elements 10 each comprise four venting slits 152, one of which is covered by a venting slit cover plate 154. The venting slits may also be construction slits 76. The venting slit cover plate 154 comprises venting means 48, the venting means being valves or holes. The venting slit 152 is in fluid communication with the central internal longitudinal channel 12 of the vertical frame element 10 (not shown) via the channel routing block 92 of the connecting device 90. The venting slit cover plate 154 seals the venting slit 152 such that fluid communication with the environment can only occur via the venting means 48. Fluid such as air with suspended impurities may thus be removed from an environment via the venting means 48, through the venting slit 152 and into the central internal longitudinal channel 12. In a similar fashion, clean air may be supplied to an environment.

Figure 18A shows a schematic image of a frame 114 comprising multiple vertical frame elements 116, multiple horizontal frame elements 118 and multiple wall elements (not shown), the frame 114 enclosing a living environment 1221 such as a house. The frame 114 may be constructed to be load-bearing. The frame comprises multiple internal longitudinal channels 12 and multiple devices 124 are connected to the frame to provide household functions, such as a shower head 1241 , a vacuum cleaner head 1242, and a lighting device 1244. The shower head 1241 is provided with water via one or more of the internal longitudinal channels 12. The vacuum cleaner head 1242 is connected to one of the internal longitudinal channels 12 which is pressurized to a pressure below atmospheric pressure, such that vacuum cleaning action is achieved. A filter may be present in the vacuum cleaner head such that vacuumed dirt is caught before entering the internal longitudinal channel 12. Alternatively, the vacuumed dirt may be removed by the internal longitudinal channel 12 and disposed or stored elsewhere. The lighting device 1244 is provided with electric power via an internal longitudinal channel 12 which is an electric power channel. Alternatively, the lighting device 1244 may be powered by a small turbine integrated in the lighting device 1244 which is powered by an airflow through one of the internal longitudinal channels 12 which is pressurized to a pressure that is different from the ambient pressure, which pressure may be either higher or lower than atmospheric pressure. An advantage of this alternative, is that no or less electric power needs to be routed through the frame 114, decreasing risk of fire and reducing the number of internal longitudinal channels 12 that is required. Furthermore, a dual functionality of both lighting and either providing fresh air to the living environment 1221 or removing air from the living environment 1221 can be achieved in a single device 124.

At least one of the frame elements 10 used in the frame 114 for surrounding a living environment 1221 further comprises venting means 48 which are in fluid communication with one of the internal longitudinal channels 12 which is pressurized to a pressure which is different from atmospheric pressure. If this pressure is higher than atmospheric pressure, the venting means supply air to the living environment 1221. If this pressure is lower than atmospheric pressure, the venting means remove air and any impurities suspended or dissolved in said air from the living environment 1221 .

The internal longitudinal channels 12 may also be used for other functions, for example to transfer data as part of an internet, phone, or other type of electronic data connection. Seeing that many media such as water (hot and/or cold, clean and/or dirty), air (hot and or cold, clean and/or dirty), waste, data and electricity are usually transported in a house, large advantages can be achieved by integrating transportation ability of at least some of these into a frame 114 enclosing the living environment 1221. These advantages include, among other things, ease of construction, flexibility of construction, increases speed of construction and lower cost.

Some or all of the features described above regarding the frame 114 enclosing a living environment 1221 may also be applied in a frame 114 used for different purposes. Such purposes include a frame 114 comprising multiple vertical frame elements 116, multiple horizontal frame elements 118 and multiple wall elements, the frame enclosing a laboratory environment, cleanroom environment or operating room environment 1222. Such a frame is shown in figure 18B. The frame 114 also comprises a fume hood 1246, wherein fumes may be evacuated form the fume hood environment through the internal longitudinal channels 12 using venting means 48 or a dedicated device 124 such as a suction head. Figure 18C shows a frame 114 comprising multiple vertical frame elements 116 and multiple horizontal frame elements 118, the frame forming a stall, booth or stand such as a market stall or an exhibition stand 1223 comprising a counter 1248.

Figure 18D shows a frame 114 enclosing a living environment 1221. The frame 114 comprises non-extendable frame elements 10, however in an alternative embodiment, the frame 114 may comprise extendable frame elements 10. Various devices 124 are connected to the frame 114, being a sink 184, a stove 182, a washing machine 188, a drain 186, a shower head 1241 and a toilet 178. Each device 124 is connected to the appropriate internal longitudinal channels 12 extending through the frame elements 10 via appropriate connectors. An external source of electric power 190 such as a power grid provides electric power to the electronic channels 59 within the frame elements 10. A first external source of fluid 192 provides a fluid such as clean water to a fluid channel 13 within the frame elements 10. A second external source of fluid 193 provides a fluid such as natural gas to a fluid channel 13 within the frame elements 10. An external fluid disposal system 194 such as a sewer allows disposal of fluid waste from the living environment 1221 .

Corresponding fluid channels 13 of different frame elements 10 may be in fluid communication with each other via the block channels 98 in the connecting devices 90. Flowever, a blocking plug may be used between adjacent frame elements 10 to ensure that corresponding fluid channels 13 of adjacent frame elements 10 are not in fluid communication with each other, such that the corresponding fluid channels 13 may be used for different purposes in the adjacent frame elements 10, for example for transporting gas in one frame element 10 and for transporting water in another frame element 10. Figure 18E shows an electronic device connected to a frame, in particular a washing machine 188. The washing machine is supplied with electric power from the electronic channel 59 via an electric power connector 1881. An electric power adapter 1884 is used to allow use of standardized electronic power connectors such as wall plugs. The washing machine 188 is further provided with fresh water from the fluid channel 13 via a fluid inlet connector 1882.

The washing machine 188 is connected via a fluid outlet connector 1883 to another fluid channel 12 to dispose of washing water after a washing cycle. In a practical application, these three connectors 1881 , 1882, 1883 may be combined in a single connector. Using the appropriate connectors, any device 124 may be supplied with the required medium for operation from the internal longitudinal channels 12 provided within the frame elements 10, including, but not limited to, electric power, cold water, hot water, cold air, hot air, pressurized air, natural gas, electric signals, data.

Figure 18F shows a section of a frame 114. The frame 114 is rigidly connected to a floor and a ceiling by fixating elements 164 comprising fixating rails 166 which are anchored to the floor and the ceiling. The imaged section of the frame 114 is thereby fixated in place, enhancing the structural rigidity of the frame 114. The frame 114 comprises a wall element 120, a window 174 and a door 176. The wall element 120 and the window 120 are connected to and supported by at least one frame element 10. The door 176 is hingedly connected to an supported by a vertical frame element 10. Using wall elements, 120, windows 174 and doors 176, a frame 114 can be used to construct houses, offices or other living or working spaces or sections thereof.

Figure 18G shows a cross section of a frame element 10 connected to a fixating element 164. The fixating element 164 engages with the frame element 10 to provide a rigid connection.

Figure 19A shows a perspective view of a connecting device 90. The connecting device comprises a channel routing block 92 and multiple connecting plugs 108 for connecting block channels to internal longitudinal channels 12 of connecting frame elements 10. Entrances to fluid block channels are arranged at a central position 156 and at a peripheral position 158, while entrances to electronic block channels are blocklet entrances 198 which are only arranged at a peripheral position 158 in an electronic channel routing blocklet 196.

Figure 19B shows a perspective view of a section of a frame element 10 comprising fluid channels 13 and an electronic channel 59. The electronic channel 59 comprises three electronic subchannels 160. The frame element 10 comprises an electronic end plug 162 for connecting the electronic channel 59 to an electronic channel routing blocklet 196. The electronic end plug 162 is rotatable over an electronic end plug rotation range in order to allow engagement of the electronic channel contact members 200 to engage with the blocklet entrances 198 of any connected connecting device, regardless of the orientation of the blocklet 196. The electronic end plug rotation range is preferably at least 90 degrees, more preferably at least 180 degrees.

Figure 19C shows an exploded view of the connecting device 90 of figure 19A and the frame element 10 of figure 19B. the connecting device 90 comprises a channel routing block 92 and multiple blocklets 196 connected by electronic block channels 985. The electronic channel 59 comprises three electronic subchannels 160. The fluid channels 13 are connected to block channels 98 via connecting plugs 108.
