Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel structure buildings, and particularly relates to a steel structure floor slab integrating a frame beam. Background Art
[0002] The traditional construction method of assembling steel structures in the form of components has a long history. By prefabricating beams and columns of various cross-sections and connecting them on-site, and then laying floor bearing plates and pouring concrete floors, the construction of the main structure can be completed quickly.
[0003] However, the floor slab is not only a structural component but also a working surface for subsequent work. Its construction process involves wet operations, which will limit the assembly speed of the building. In addition, the on-site installation of secondary beams, laying of floor slabs, and casting of post-cast concrete still have cumbersome procedures. Moreover, once the concrete is poured, the structure becomes a non-modular structure that cannot be disassembled and replaced.
[0004] However, in steel structure buildings that need to be disassembled, there is a contradiction between the in-situ casting operation of the floor slab and the detachable nature of the full bolt connection of beams and columns. In addition, the floor slab has the problems of complex on-site construction procedures and too long construction period. Content of the Utility Model
[0005] The purpose of the utility model is to provide a steel structure floor slab integrating a frame beam to solve the above problems, realizing no on-site wet operation, integrating the frame beam into the floor slab module, simplifying the on-site construction process, and having the advantages of modularization.
[0006] Technical Solution: The utility model provides a steel structure floor slab integrating a frame beam, including: a floor slab frame, keels, a structural surface layer, and a floor. The floor slab frame is composed of frame beams connected by welding; there are several keels, which are evenly arranged between the floor slab frames; the structural surface layer is arranged above the floor slab frame and the keels and is fixed by self-tapping and self-drilling screws; the floor is arranged above the structural surface layer and has the same shape and area as the structural surface layer.
[0007] Furthermore, for the above-mentioned steel structure floor slab integrating a frame beam, the frame beam and the column adopt a flange connection structure. Connection steel plates are welded at both ends of the frame beam. The length of the connection steel plate is greater than the height of the frame beam. Bolt holes are provided on the connection steel plate. Stiffening plates are arranged on both the upper and lower sides of the frame beam. The stiffening plates are triangular and are connected to the frame beam and the connection steel plate by welding. The adjacent connection steel plates are connected by welding, and the adjacent connection steel plates are connected at 90°, forming an installation end of the column, which is convenient for fixed connection with the column. This improves the structural strength of the floor slab and enhances the integrity.
[0008] Furthermore, for the above steel structure floor slab with an integrated frame beam, for the frame beam in the floor slab frame connected to the keel, angle steel is provided on the inner side of the web. The angle steel is welded to the frame beam, and the keel is fixed to the angle steel through self-tapping and self-drilling screws, which can reduce welding operations and control component deformation.
[0009] Furthermore, for the above steel structure floor slab with an integrated frame beam, the keel adopts cold-formed thin-walled steel with an open cross-section. It can reduce the self-weight and facilitate the operation of self-tapping and self-drilling screws.
[0010] Furthermore, for the above steel structure floor slab with an integrated frame beam, the keel is flush with the top surface of the frame beam
[0011] Furthermore, for the above steel structure floor slab with an integrated frame beam, the structural surface layer adopts magnesium oxychloride board or oriented strand board.
[0012] Furthermore, for the above steel structure floor slab with an integrated frame beam, the structural surface layer is provided with chamfers at the four corners of the floor slab frame. The length of the chamfer is the same as the length of the stiffening plate, reserving space for bolt connection to facilitate construction during installation.
[0013] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects: For the steel structure floor slab with an integrated frame beam of the present utility model, the frame beam is integrated into the floor slab, simplifying the on-site construction process. Through bolt connection, it is convenient for installation and disassembly, providing the function of repeated disassembly and assembly, improving the assembly speed of the building, and being beneficial to small temporary buildings that require repeated installation and disassembly.
