Problems solved by technology
However, in this splicing method, the shear force is transmitted to the web through bolts, and the web is a flat steel plate, so the number of bolts required and the amount of steel used for the web are large, and the shear bearing capacity needs to be improved
At the same time, when applied to a large-span fabricated steel structure system, the traditional fabricated steel components need to greatly increase the height and area of the beam section, increasing the amount of steel used
[0003] It can be seen that the effect of using traditional steel components in the fabricated steel structure system is not very satisfactory, which not only affects the mechanical performance of the components, but also consumes a large amount of steel, resulting in unnecessary waste

Embodiment Construction
[0040] The present invention is described in detail below in conjunction with accompanying drawing:
[0041] as attached figure 1 As shown, the splicing position of the prefabricated floor slab of the present invention is set at a place where the shear force and bending moment are relatively small in the main beam. From the perspective of structural mechanics, the setting of the splicing position is very reasonable.
[0042] as attached Figure 2-23 As shown, the present invention proposes a multi-high-rise assembled steel structure occlusal steel beam prestressed central support system, which is characterized in that the A plate is composed of a short main beam I1, a secondary beam I4, a secondary beam II5, a stiffening plate 6, a floor slab 7, Column base 8, connecting plate II17 and connecting plate III25; all the components of the A plate are processed and manufactured in the factory, and then the components are assembled into the prefabricated floor A by welding and bolt...

The invention discloses a multi-high-rise assembled type steel structure gripping steel beam pre-stress center supporting system, and belongs to the technical field of structural engineering. The multi-high-rise assembled type steel structure gripping steel beam pre-stress center supporting system is formed by assembled type floors, assembled type center supports and assembled type flange columns in an assembled mode through bolts. The assembled type floors comprise A plates, B plates and C plates and are assembled through the bolts to form an overall floor of a building, and each corrugated web gripping steel beam is formed by two corrugated steel channel beams in an assembled mode through bolts and frame ropes. According to the multi-high-rise assembled type steel structure gripping steel beam pre-stress center supporting system, on-site assembling is carried out completely through the high-strength bolts, environment pollution caused by concrete pouring and steel welding is avoided, structural members can be efficiently recycled when being disassembled, construction waste is reduced, the environment-friendly idea is truly achieved, and the multi-high-rise assembled type steel structure gripping steel beam pre-stress center supporting system is an environment-friendly structural system.
Description
technical field [0001] The invention relates to a multi-high-rise assembled steel structure occlusal steel girder prestressed central support system, belonging to the technical field of structural engineering. Background technique [0002] Traditional steel structure residential buildings have not fully utilized the advantages of steel structure residential buildings. With the continuous development of steel structure building technology in my country, multi-high-rise steel structure systems should adopt design modularization and component standardization to promote industrialization with standardization and promote industrialization with industrialization. However, in the prefabricated steel structure system, the on-site assembly of beams and beams is a key issue. In the existing prefabricated steel structure system, two channel steels are usually used for assembly, and the webs of the two channel steels are butted and connected by bolts to form a prefabricated H-shaped stee...
