Description

Technical Field

[0001] The utility model relates to the technical field of steel structure buildings, in particular to an assembled column-plate structure. 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, laying floor decking and pouring concrete floors, the main structure can be quickly completed, and then the maintenance structure can be constructed on site.

[0003] On the one hand, floor slabs serve not only as structural components but also as work surfaces for subsequent construction. However, their construction involves wet work, which limits the speed of building assembly. On the other hand, maintenance structures are typically large, requiring significant on-site work and prolonging the construction period. Overall, the prefabrication rate of traditional steel structures could be further increased, thereby shortening the construction period. Utility Model Content

[0004] The purpose of the utility model is to provide an assembled column-plate structure to solve the above-mentioned problems, simplify the on-site construction process, eliminate on-site wet work, and shorten the construction period.

[0005] Technical solution: The utility model provides an assembled column-slab structure, including: a prefabricated foundation, a connecting piece, a column, a prefabricated floor slab, and a prefabricated wall panel. The bottom of the prefabricated foundation is a quadrangular pyramid structure, and the upper part is a connecting part. The prefabricated foundation is made of foundation steel bars and then cast as a whole; the connecting piece is fixedly connected to the steel bars in the connecting part by welding before the prefabricated foundation is cast. The connecting piece includes: a mounting plate, a stiffening rib plate, and a connecting plate. The stiffening rib plates and the connecting plate are symmetrically arranged on the upper and lower sides of the mounting plate. The stiffening rib plates are cross-shaped and arranged on the upper and lower sides of the mounting plate. In the middle of the side, the connecting plate is arranged around the stiffening ribs and connected to the mounting plate. The columns are connected to the prefabricated foundation by being mounted on the connecting pieces. Screw holes are provided at both ends of the columns. The columns are also connected by connecting pieces when stacked upwards. The columns are made of square steel pipes. The prefabricated floor slabs are arranged horizontally between the columns, and the four corners are fixedly connected to the screw holes in the columns by bolts. The prefabricated wall panels are arranged between the columns and connected to the columns on both sides. The upper part of the prefabricated wall panels is connected to the prefabricated floor slabs by wall panel connectors, and the lower part of the prefabricated wall panels is connected to the prefabricated floor slabs by self-drilling screws. The modular building structure uses bolts to connect the modules, simplifying the on-site construction process, shortening the construction period, and reducing costs.

[0006] Furthermore, in the above-mentioned assembled column-plate structure, the connecting plate is provided with fixing screw holes corresponding to the screw holes at both ends of the column.

[0007] Furthermore, in the above-mentioned assembled column-slab structure, the prefabricated foundation is made by pouring reinforced concrete.

[0008] Furthermore, in the above-mentioned assembled column-slab structure, the prefabricated floor slab includes: a floor slab frame, a floor slab surface layer, and a connecting steel plate. The floor slab surface layer is arranged on the upper side of the floor slab frame, and the four corners of the floor slab frame are designed with right-angled concave structures to reserve column connection positions, and connecting steel plates are arranged at the concave parts.

[0009] Furthermore, in the above-mentioned assembled column-plate structure, the connecting steel plate is provided with fixing screw holes corresponding to the screw holes at both ends of the column, and the prefabricated floor slab and the column are fixedly connected by bolts.

This improves the sealing performance and structural strength of the prefabricated wall panel.

[0012] Furthermore, in the above-mentioned prefabricated column-plate structure, the wall panel connector is L-shaped, with one side connected to the floor frame by welding and the other side aligned with the T-shaped steel connector. This facilitates the installation of prefabricated wall panels and improves the connection strength.
