Description

Technical Field

[0001] The utility model relates to the field of steel structure buildings, and particularly relates to a steel structure floor module with convenient construction. 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 not only serves as a structural member but also as 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, floor laying, and 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] In steel structure buildings that need to be disassembled, there is a contradiction between the cast-in-place operation of the floor and the detachable nature of the full bolt connection of beams and columns. To achieve the detachable nature of the floor and further simplify the on-site construction procedures of the floor and shorten the construction period, this application proposes a steel structure floor module with convenient construction. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a steel structure floor module with convenient construction to solve the above problems, without on-site wet operations, integrating various processes from secondary beams to the floor surface, and adopting an optimized connection form for the main and secondary beams of traditional steel structures, having the advantages of modularization and convenient assembly.

[0006] Technical Solution: The utility model provides a steel structure floor module with convenient construction, including: a floor unit, the floor unit includes: secondary beams, main keels, and secondary keels. The secondary beams and the main keels are welded to form a floor frame. There are several secondary keels, which are evenly arranged in the floor frame, and the secondary keels are parallel to the secondary beams;

[0007] Main beams and floor steel columns, the main beams and the floor steel columns are welded to form a rectangular outer frame of the floor module;

[0008] Several floor units are combined and connected together, and the connecting part shares a secondary beam and is arranged in the outer frame of the floor module. The secondary beams and the main beams are both H-shaped steels. A rib plate corresponding to the position of the secondary beam in the floor unit is provided on the inner web of the main beam, and the rib plate is fixedly connected to the web of the secondary beam by bolts. This avoids on-site wet operations, simplifies the construction procedures, improves the assembly speed, and the floor is detachable and convenient for transportation.

[0009] Further, in the above-mentioned steel structure floor module with convenient construction, a structural surface layer is provided above the outer frame of the floor module.

[0010] Furthermore, for the above-mentioned steel structure floor slab module with convenient construction, the structural surface layer adopts magnesium oxychloride board or oriented strand board (OSB).

[0011] Furthermore, for the above-mentioned steel structure floor slab module with convenient construction, a floor is arranged above the structural surface layer.

[0012] Furthermore, for the above-mentioned steel structure floor slab module with convenient construction, the secondary beams are cross-connected with the rib plates. The webs of adjacent secondary beams 1 are connected to the corresponding rib plates, and the webs are respectively connected to different sides of the rib plates. During the subsequent installation of the wall panels, they can be firmly fixed in place by hoisting, which is convenient for the subsequent bolt fixing work.

[0013] Furthermore, for the above-mentioned steel structure floor slab module with convenient construction, several outer frames of the floor slab module are connected together by welding. The connecting parts share a main beam to form a suitable floor slab size to meet the requirements of different floor slab dimensions.

[0014] Furthermore, for the above-mentioned steel structure floor slab module with convenient construction, the structural surface layer overlaps at the 1 / 2 width of the main beam. After the structural surface layer is installed, there is a gap between the top surfaces of the outer frames of the floor slab module, and a T-shaped sealing strip is inserted into the gap for sealing. This prevents the liquid on the floor slab from flowing into the gap and leaking downstairs.

[0015] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects: The steel structure floor slab module with convenient construction of the present utility model avoids on-site wet operations, simplifies the construction process, integrates various processes from secondary beams to the floor surface, and adopts an optimized connection form of traditional steel structure main and secondary beams.
