Title:
HAMMERING ASSEMBLY TYPE FIXING DEVICE FOR SHIPYARD
Document Type and Number:
WIPO Patent Application WO/2017/138767
Kind Code:
A1
Abstract:
The present invention provides a hammering assembly type fixing device for a shipyard, in which the lower end of a fixture is inserted into a fixing groove formed in a fixing plate (made of a rigid bottom such as steel, concrete, rock, etc.) and the upper end of the fixture is screwed to be coupled to a separate fastening element, such that a grating, a work foothold, etc. are fixed. The hammering assembly type fixing device for a shipyard according to the present invention is configured such that a protruding flange inclined downward is integrally formed with a fixture to form a single body at a portion where an upper end and a lower end of a fixture are connected to each other, and a packing ring is provided to be inserted into the lower end of the fixture in close contact with the protruding flange. As such, as the fixture is fixed to the fixing plate by the pressing from the hammering, the hammering assembly type fixing device has the characteristics of being resistant to lateral forces and preventing breakage of the lower end due to a primary fixing by the lower end and a secondary fixing by the protruding flange. Further, the pressing force of the protruding flange of a downwardly inclined structure, and the improved sealing property by the packing ring, and the excellent foreign substance blocking effect are obtained. Moreover, the manufacturing process of the fixture is simplified, thereby reducing the manufacturing cost. Especially, the hammering assembly type fixing device for a shipyard is applied to fix a grating installed in a shipyard, so that even in high salt conditions due to the inflow of seawater through various routes in shipbuilding processes, the fixing force of the fixture with respect to the fixing plate is maximized and the airtightness by the packing ring is improved, thereby preventing the occurrence of fine gaps between the fixing plate and the fixture. Therefore, the penetration of salt is blocked, thereby preventing the corrosion of the fixture and improving durability of the fixture.
