Field of the Invention

The present invention relates to the field of fluid pipeline connections within poured concrete walls, ceilings and floors. More specifically, the invention pertains to a novel pipe designed with a dual internal sealing ring configuration, offering significant advancements in the installation of pipelines within poured concrete structures.

Background

In the construction industry, multiple-unit structures, buildings, offices and housing structures are commonly constructed using concrete floors and slabs to ensure structural stability and load-bearing capacity. To enable the installation and supply of plumbing, efficient positioning of fluid-flowing pipelines from the bases of the structures to their top floors is crucial. The conventional method for achieving this task involves several stages as follows:

1. Casting: In this initial stage, the concrete floor or slab of a housing structure is cast following generally accepted construction standards. Based on the constructor's specifications, a location for a pipe to pass through is identified, and a soft material, such as polystyrene, is used to temporarily seal the opening, facilitating easier foramen formation.

2. Preparation: During this stage, a hole-forming device is securely aligned and secured to create the foramen with the desired diameter for the fluid-flowing pipeline. It should be emphasized that the foramen formation process can distort the shape of the opening.

3. Layout: In this stage, the desired pipeline is laid through the created foramen in the ceiling and further sealed to prevent movement during usage. Due to the shape distortion of the opening, sealing the opening typically requires additional effort, leading to unnecessary expenses. Overall, the layout procedure of fluid-flowing pipelines in this manner is characterized by ergonomic challenges, time-consuming processes, and inefficiencies. Additionally, a significant drawback is the potential formation of cracks in pipes, which can be caused by pressure changes and ground settling over time. Ground settling, in particular, may lead to pipe damage if the stress applied to the pipes is sufficient, resulting in eventual cracking or breakage.

To address these issues, the present invention aims to provide a more efficient and reliable solution for pipeline installation. It introduces a specially designed pipe for forming holes and openings through concrete or other poured construction materials.

The present invention is related to a pipeline connector designed for forming holes and openings that continuously extend through poured concrete structures, such as floors and slabs. The pipe is intended to be installed within a wall or shell, resulting in a duct in the finished state.

The core aspect of the invention revolves around a pipeline connector that comprises a dual sealing ring configuration within a pipe in the form of a cylindrical sleeve. According to an embodiment of the invention, at least one end of the pipeline connector (e.g., an upper section of the pipeline connector) features two separate internally assembled rubber layers that form the dual sealing ring configuration. According to an embodiment of the invention, the pipeline connector with dual internal sealing rings is designed for seamless pipeline connections within poured concrete structures. At each end of the pipeline connector, there are dedicated corresponding grooves in the inner wall, and the two internal sealing rings are precisely matched to these grooves. The outer ring, positioned closer to the pipeline connector's exterior, acts as a protective barrier during the concrete pouring process, ensuring the integrity of the second inner sealing ring. Thus, the first sealing ring serves as a blockage, preventing wet concrete from contacting the second inner sealing ring, and the actual sealing is performed by the second inner sealing ring, ensuring a reliable and secure seal between connected pipes. This unique dual-ring configuration enhances sealing performance, providing redundancy and reliability, even in the event of damage to the outer ring.

The pipeline connector of the present invention streamlines the pipeline installation process, eliminating the need for additional sealing materials or complex jointing methods. As a result, fluid flows smoothly from one pipe to another, facilitating efficient transfer within the constructed ducts. The dedicated design of the pipeline connector's sealing rings prevents wet concrete from compromising the integrity of the inner ring, ensuring long-lasting and effective sealing performance.

According to an embodiment of the invention, the dual sealing ring configuration further ensures an optimal internal grip of a corresponding first fluid-flowing pipeline received at one end of the pipeline connector (e.g., the upper end with respect to a ceiling installation of the pipeline connector, i.e., in a vertical flow direction). Similarly, the other end of the pipeline connector (e.g., the lower end) is equipped with two separate internally assembled rubber layers (i.e., that form the dual sealing ring configuration) to achieve the same optimal internal grip of a corresponding second fluid-flowing pipeline received at the other end the pipeline connector (e.g., the lower end).

According to an embodiment of the invention, the internal sections of both ends of the pipeline connector are separated by an inclined rubber layer, either integrated or added to the sleeve, which serves to prevent fluid leakage from the side walls of the pipe.

According to an embodiment of the invention, both ends of the pipeline connector have graded external frameworks to enable optimum adjustments during the concrete casting process.

In some embodiments, one end of the pipeline connector (e.g., the end that may serve as a lower end with respect to a vertical flow installation) comprises a flange that forms a base-like structure at that end of the pipe. The base-like structure exceeds the diameter of the cylindrical sleeve allowing secure attachment of the pipeline connector to a concrete-forming baseplate using nailing, screwing, or other suitable securing means.

Referring to the provided drawings, Fig. 1 schematically illustrates a pipeline connector 10 in the form of a cylindrical sleeve 8, according to an embodiment of the invention. Pipeline connector 10 comprises two internal sealing rings, a first sealing ring 2 and a second sealing ring 3, each fitted into dedicated corresponding grooves 12 and 13 in an inner wall 6 of pipeline connector 10 that forms the dual sealing ring configuration. In this embodiment, the dual sealing ring configuration applies at about both end sections of pipeline connector 10, symmetrically. Each of the two internal sealing rings 2 and 3 is a sealing rubber tightly placed against the side walls of pipeline connector 10 within the corresponding grooves 12 and 13, effectively preventing fluid leakage and providing optimal internal grip for each connected pipeline at each end of pipeline connector 10 (see Fig. 2). Wherein the first sealing ring 2 is positioned closer to the exterior of pipeline connector 10, acting as a protective barrier against wet concrete during the pouring process, and wherein the second sealing ring 3 is positioned closer to the interior of the pipe, serving as the primary sealing element. The inner space of pipeline connector 10 is indicated by the numeral 7.

According to an embodiment of the invention, pipeline connector 10 comprises a flange 9 that forms a broader and flat base-like structure at each end of the pipe. As shown in the figure, the base-like structure exceeds the diameter of pipeline connector 10, allowing secure attachment of pipeline connector 10 to a concreteforming baseplate using nailing, screwing, or other suitable securing means. Flange 9 has several holes 1 around its perimeter, allowing bolts or screws to securely fasten them to the concrete-forming baseplate (not shown). Flange 9 can be fixed in place during the construction of a concrete ceiling by assembling screws via holes 1, and the specific external structure allows for optimal adjustments during the casting stage.

Fig. 2 demonstrates a pipeline connector 10 with two separate assembled pipes 4 and 5, inserted through its ends, according to an embodiment of the invention. This configuration allows connecting two separate pipes 4 and 5, enabling fluid communication between them, while the inner space 7 of pipeline connector 10 serves as a fluid transfer medium between the two pipes 4 and 5. Moreover, the flexible connection provided by the dual ring configuration prevents the formation of cracks in the pipes, which may be caused by pressure changes or ground settling in the sleeve surroundings.

According to an embodiment of the invention, the flexible connection provided by the dual ring configuration prevents the formation of cracks in the pipes due to the following key reasons:

Absorption of Movement: The presence of two internal sealing rings in the pipeline connector 10 allows for some degree of movement or flexing between the connected pipes. When pressure changes occur within the pipeline or when the ground settles, these dual sealing rings absorb and distribute the stress or movement along the length of the pipeline. This flexibility prevents concentrated forces from being exerted at specific points, which significantly reduces the risk of cracks forming in the pipes; and

Stress Redistribution: As pressure changes or ground settling affect the surrounding environment of the pipeline, there may be slight shifts or displacements in the pipeline. The dual sealing rings act as a buffer, redistributing the stress caused by these movements across their surface area. This redistribution of stress helps to maintain the structural integrity of the pipeline, ensuring that no single point is subjected to excessive stress or strain, thereby mitigating the formation of cracks.

Fig. 3 schematically illustrates an extender 20 designed to partially receive the pipeline connector 10, forming a cylindrical telescopic/adjustable sleeve, according to an embodiment of the invention. This combination enables fitting pipeline connector 10 to different structure widths of a ceiling, wall, or any other suitable structure. Extender 20 comprises a dual sealing ring configuration similar to the dual sealing ring configuration of pipeline connector 10, where the two internal sealing rubber rings 22 and 23 are placed against its side walls 26 within corresponding grooves 32 and 33, similar to the internal structure of pipeline connector 10. Extender 20 can be fixed in place during the construction of a concrete ceiling by assembling screws via holes 27 and/or 28 of a flange 29 located at the end of extender 20.

In Figs. 4A and 4B, pipeline connector 10 is partially inserted into extender 20, allowing height adjustment by setting the desired length of the combined sleeve to fit the width of a wall or ceiling. In this embodiment, the two internal sealing rubbers rings 22 and 23 of extender 20 adapted to sealingly grip one end of pipeline connector 10 inserted into it. In order to insert pipeline connector 10 into extender 20, one end of pipeline connector 10 needs to be cut (e.g., by any suitable cutting or sawing tool). Fig. 4C schematically illustrates pipeline connector 10 after cutting one end to enable its insertion into extender 20. One end of pipeline connector 10 is designed to fit snugly and securely into a corresponding end of extender 20. Notably, at that end, extender 20 possesses a larger diameter than pipeline connector 10. In contrast, the other end of extender 20 maintains the same diameter as pipeline connector 10. As a result of this strategic design, the combination of pipeline connector 10 and extender 20 yields an adjustable version of the original connector 10.

The adjusted version of pipeline connector 10 created by this combination is achieved by inserting one end of the connector 10 into the wider diameter of the extender 20, creating a telescopic and adaptable structure. This telescopic design facilitates the accommodation of various structure widths, such as walls or ceilings, through which the pipeline needs to pass. The adjustment is achieved by determining the insertion depth of the pipeline connector 10 into the extender 20. Through this adjustment, the combined assembly of the pipeline connector 10 and the extender 20 can be precisely customized to match the specific construction thickness required for the concrete building.

This innovative mechanism of adjusting pipeline connector 10 through the use of the extender 20 enhances the versatility and practicality of the pipeline installation process. It enables a seamless fit within different structure widths, contributing to the efficiency and effectiveness of the pipeline connections within poured concrete walls and ceilings.

The un-inserted end of pipeline connector 10 is purposefully designed to seamlessly receive and connect with a first pipe (e.g., such as pipe 5 of Fig. 2). On the other hand, the opposite end of extender 20 is also meticulously configured to accommodate and securely connect with a second pipe (e.g., such as pipe 4 of Fig. 2). When the two pipes (e.g., pipes 4 and 5) are effectively inserted into the respective ends of pipeline connector 10 and extender 20, a continuous pipeline is established.

This interconnected system results in a pipeline arrangement wherein the first and second pipes are in fluid communication, facilitated by the seamless combination of pipeline connector 10 and extender 20. The innovative design of pipeline connector 10 and extender 20 with dual sealing ring configuration ensures that fluid can flow seamlessly from the first pipe (e.g., pipe 4), through pipeline connector 10, along extender 20, and into the second pipe (e.g., pipe 5). The dual-component assembly (i.e., pipeline connector 10 and extender 20) forms a reliable conduit that enables efficient fluid transfer between the two separate pipes while maintaining a sealed environment, thus enhancing the overall functionality and reliability of the pipeline system.

In the combined assembly of pipeline connector 10 and extender 20, it's important to note that extender 20 incorporates the dual ring configuration (i.e., by the two internal sealing rubbers rings 22 and 23 and the corresponding grooves 32 and 33) specifically on the inserted cut end of pipeline connector 10.

This strategic implementation ensures that the benefits of the dual-ring design are extended to the adjustable version of the pipeline connector. The dual ring configuration of extender 20 on the inserted end pipeline connector 10 maintains the enhanced sealing performance, reliability, and stress-absorbing attributes, just like in the original pipeline connector 10. As a result, the entire assembly maintains the integrity of the fluid conduit, preventing leakage and providing flexibility to accommodate variations in structure width. This innovative integration of the dual ring configuration within extender 20 further enhances the overall effectiveness and adaptability of the pipeline connection system.

With this regard, it is important to highlight that the dual ring configuration is not only implemented within the connection of pipeline connector 10 and extender 20 but also extends to the connection points with the first and second pipes, such as with pipes 4 and 5.

Specifically, the end of pipeline connector 10 that receives the first pipe features the same dual-ring configuration. This ensures that the first pipe is effectively sealed and securely connected, benefiting from the enhanced sealing performance provided by the dual ring design. Likewise, the end of the extender 20 that accommodates the second pipe is also equipped with a dual-ring configuration. This guarantees that the second pipe is properly sealed and connected, thereby maintaining the reliability and efficiency of the fluid transfer through the entire assembly.

The dual ring configuration spans across pipeline connector 10, extender 20, and the respective connection points with the first and second pipes. This comprehensive integration ensures consistent and effective sealing performance at every crucial juncture, establishing a robust and reliable pipeline connection system within poured concrete structures.

In a further embodiment of the present invention, both ends of the pipeline connector are designed with graded external frameworks. These frameworks consist of a series of structural modifications on the outer surface of the connector, such as ridges, grooves, protrusions, or other variations (e.g., as indicated by numeral 30 in Figs. 4A and 4B, as well as the protrusion outer surface of grooves 12 and 13, etc.). This graded design serves multiple purposes:

Enhanced Grip: When the pipeline connector is placed within wet concrete, the graded structures offer improved anchoring. As the concrete sets and hardens, these graded modifications ensure that the connector remains firmly embedded, resisting any potential dislodgment or movement.

Facilitated Adjustments: The graded external frameworks provide flexibility during the concrete casting process. If there's a need to make minor positional adjustments to the connector after its placement in the wet concrete, these structural features allow for such modifications, ensuring the connector's optimal alignment and positioning.

Improved Sealing: As the concrete solidifies around the graded external frameworks, it forms a more intimate bond with the connector. This results in a tighter seal, minimizing potential leaks or seepage around the connector and ensuring the integrity of the connection. This design of graded external frameworks, therefore, not only enhances the structural stability of the pipeline connector within concrete structures but also ensures its functional efficiency, making it a valuable feature in various construction scenarios.

Fig. 5 schematically illustrates a cross-sectional view of pipeline connector 10, featuring an inner ring 16 designed to prevent leakages by directing fluid toward the center of pipeline connector 10, away from the inner walls 6. The inner ring 16 may have a triangular-like profile to achieve this effect.

As the skilled person will appreciate, the arrangement described in the figures results in a pipeline connector with dual internal sealing rings offering significant advantages over traditional pipeline installation methods within poured concrete structures. These advantages include:

Enhanced sealing performance: The dual ring configuration provides a reliable and secure seal between connected pipes, reducing the risk of leakage.

Redundancy and reliability: The second inner sealing ring offers redundancy, ensuring continued sealing performance even in the event of damage to the outer ring.

Protection against concrete impairment: The first sealing ring acts as a barrier, safeguarding the second inner sealing ring from the detrimental effects of wet concrete during the pouring process.

Efficient pipeline installation: The innovative pipe streamlines the pipeline installation process, eliminating the need for additional sealing materials and reducing installation time.

Long-Term Durability: The dedicated design of the pipeline connector's sealing rings ensures long-lasting sealing performance, providing a reliable solution for pipeline connections.
