Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixing device technology, specifically a fixing device for prefabricated, non-removable floor decking. Background Technology
[0002] Prefabricated, non-removable floor decking is a new type of prefabricated building material. It is composed of a steel truss and a fine aggregate concrete base slab through an integrated process. It can be prefabricated in the factory and directly installed on the construction site without dismantling after construction. This type of floor decking not only simplifies the construction process and improves construction efficiency, but is also widely used in various construction projects such as factories, schools, and hospitals. During the construction process, prefabricated, non-removable floor decking needs to be fixed in place to ensure its stable installation in the predetermined position, preventing displacement or detachment, thereby ensuring the structural safety and stability of the building. When fixing existing floor slabs, steel plates are generally installed at the bottom of the joint between two floor slabs. This can effectively distribute and bear the load at the joint and connect the two floor slabs, thereby enhancing the overall load-bearing capacity of the floor slab. However, the surfaces of the floor slab and the steel plate are not smooth, and gaps will remain at their joints. This makes it impossible for the steel plate to bear the force evenly, and the steel plate will deform under the heavy pressure of the floor slab. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] To address the shortcomings of existing technologies, this invention provides a prefabricated, non-removable floor deck fixing device, which solves the problems of uneven stress and deformation of the steel plate.

[0014] (III) Beneficial Effects
[0015] Compared with the prior art, this utility model provides a prefabricated, non-removable floor decking fixing device, which has the following beneficial effects:
[0016] 1. This utility model involves inserting a wedge into the larger gap between the bearing plate and the receiving steel plate, welding the wedge to the receiving steel plate, and then injecting structural adhesive into the injection hole so that the receiving steel plate can bear the pressure of the bearing plate evenly as a whole. Then, concrete is poured into the round hole. This can effectively transfer and disperse stress and prevent damage caused by excessive local pressure.
[0017] 2. This utility model strengthens the rigidity of the supporting steel plate and prevents bending by installing a U-shaped hoop plate at the bottom of the supporting steel plate and then installing a strip block on the top of the supporting plate and welding a third rivet and nut. At the same time, the strip block connects the two supporting plates, which can improve the stability of the supporting plate.
[0018] 3. When connecting the first and second bearing plates, this utility model uses a second rivet to pass through the connecting block and fix it to the crossbeam. Then, the strip groove of the bearing steel plate is aligned with the mounting block and fixed with the first rivet. The strip groove facilitates fine-tuning of the position and improves installation efficiency. After installation, the edge of the mounting block is welded to the insert block to ensure that the bearing steel plate is firmly fixed to the bottom of the floor joint, effectively dispersing the load and enhancing the overall load-bearing capacity of the floor.

The tops of the two lugs 401 are respectively attached to the first deck 1 and the second deck 104, and a third rivet 402 is movably connected to the middle of the lugs 401. A strip block 403 is provided at the top of the third rivet 402. By adding the wedge 202 between the two decks and the supporting steel plate 2 and injecting glue into the injection hole 101, the supporting steel plate 2 is subjected to uniform force.
[0029] In a preferred embodiment, crossbeams 103 are fixedly connected to both ends of the bottom of the first support plate 1, and the first support plate 1 and the second support plate 104 are of the same size.
[0030] In a preferred embodiment, a crossbeam 103 is fixedly connected to both ends of the first support plate 1. A second rivet 305 is welded to the inner side of the crossbeam 103. A connecting block 304 is welded to the surface of the second rivet 305. An installation block 302 is installed inside the connecting block 304.
[0031] In a preferred embodiment, a circular hole 102 is provided at the top of the first support plate 1, a third rivet 402 is provided in the inner wall of the circular hole 102, and a U-shaped hoop plate 4 is installed at the bottom of the third rivet 402.
[0032] In a preferred embodiment, reinforcing ribs 201 are fixedly connected to both sides of the receiving steel plate 2.
[0033] In a preferred embodiment, an insert block 3 is installed inside the mounting block 302, and a strip groove 301 is formed on the surface of the insert block 3. A first rivet 303 is welded to the inside of the strip groove 301 and the surface of the mounting block 302.
[0034] In a preferred embodiment, the wedge 202 is made of steel.
[0035] In a preferred embodiment, the top of the strip block 403 is provided with a gasket 404, the interior of the gasket 404 is provided with a third rivet 402, and the top of the gasket 404 is welded with a nut 405.
[0036] The working principle of this utility model is as follows: When it is necessary to connect and fix the first bearing plate 1 and the second bearing plate 104, the second rivet 305 is passed through the connecting block 304 and inserted into the crossbeam 103. Then, the second rivet 305 is welded to the connecting block 304. Subsequently, the strip groove 301 on the bearing steel plate 2 is inserted into the mounting block 302, and the first rivet 303 is passed through the strip groove 301 to fix the bearing steel plate 2 to the mounting block 302. The strip groove 301 allows for fine adjustment of the position of the bearing steel plate 2 during installation, which facilitates the rapid installation and positioning of the bearing steel plate 2 and improves construction efficiency. After installation, the mounting block 302 is welded to the insert block 3 along its edge. By firmly fixing the bearing steel plate 2 to the bottom of the floor joint, the load at the floor joint is effectively distributed and borne, enhancing the overall load-bearing capacity of the floor. To make the connection between the first bearing plate 1 and the second bearing plate 104 tighter, a third rivet is used. Nail 402 passes through the pre-drilled round hole 102 on the bearing plate. Then, the lug 401 on the U-shaped hoop plate 4 is installed on the third rivet 402 and fixed with nut 405. Then, a strip block 403 is installed on the top of the bearing plate and passes through the third rivet 402, and is also fixed with nut 405. After fixing, the connection between the third rivet 402 and nut 405 is welded with a welding gun. This setting strengthens the rigidity of the bearing steel plate 2 and prevents the bearing steel plate 2 from bending due to excessive pressure. At the same time, the strip block 403 connects the two bearing plates and improves stability. After installation, check whether there are gaps between the bearing plate and the bearing steel plate 2. Insert wedge 202 into the gaps where they are larger and weld the wedge 202 to the bearing steel plate 2. Then, inject structural adhesive into the injection hole 101 so that the bearing steel plate 2 can bear the pressure of the bearing plate evenly as a whole. Then, pour concrete into the round hole 102. This can effectively transfer and disperse stress and prevent damage caused by excessive local pressure.
