Structural system of steel structure modular building

Abstract

The invention provides a structural system of a steel structure modular building. The structural system comprises a plurality of unit modules of the modular building, wherein each unit module comprises a steel structure unit frame formed by assembling special-shaped stand columns and cross beams; each special-shaped stand column comprises a stand column body, a top face end plate and a bottom face end plate, wherein the top face end plate and the bottom face end plate are arranged at the top end and the bottom end of the stand column body; each stand column body comprises two webs perpendicularly connected at one side edge and flange plates perpendicularly connected with the two webs correspondingly, wherein the two flange plates are close to each other, and a gap is reserved between the two flange plates; the adjacent special-shaped stand columns are assembled through connecting plates; each connecting plate comprises three plane plates which are perpendicularly connected, wherein a right angle formed by two plane plates and the third plane plate form at least one right-angle quadrant; and the ends of the special-shaped stand columns are placed in the right-angle quadrants of the connecting plates in a matched mode and fixed through bolts. The structural system is simple in structure and good in joint stress performance, and 100% prefabrication of the building is achieved.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a structural system of a steel structure modular building. Background technique [0002] Modular building is a kind of prefabricated building developed on the basis of plate building. This kind of modular building has a high degree of factory prefabrication and quick on-site installation. Not only can the structural part of the frame box be completed in the factory, but also the indoor soft and hard decoration can be installed together. After being transported to the site, the modules can be hoisted and the pipelines can be connected before use. [0003] At present, the advantages of modular buildings are more obvious, but the processing of nodes is still relatively difficult. There are obvious characteristics of "eight columns and sixteen beams" at the junction of the connection nodes of the modular building. The space can be divided into eight quadrants, but th...

[0003] At present, the advantages of modular buildings are more obvious, but the difficulty of processing nodes is still relatively large

There are obvious characteristics of "eight columns and sixteen beams" at the junction of the connection nodes of the modular building. The space can be divided into eight quadrants, but the eight modules will occupy the entire space, and there is no space for construction; it will be difficult to operate outside the modules Complete the stable connection of the nodes; and if you operate inside the module, it will be affected by the interior wall; if you do not prefabricate the interior wall, complete the connection of the nodes on site before building the interior wall, it will not be possible to realize the modularization of the interior decoration of the building

[0004] Therefore, the current modular building with connection nodes cannot meet the requirements of "full decoration" modules, and is only suitable for low-rise buildings, not for multi-story and high-rise buildings.
