Multi-module structure and its connection method for 3D box-type assembled light steel structure

Abstract

The invention discloses a multi-module structure for a three-dimensional box-type fabricated lightweight steel structure and a connecting mode thereof and relates to the technical field of construction. Upper guide rails, corner columns and lower guide rails form frame modules, and the frame modules are connected through corner parts, vertical bolts, horizontal bolts, longitudinal bolts and connecting plates. The corner parts are welded at the upper ends and the lower ends of the corner columns, and the connecting plates are arranged between the corner parts of upper and lower layers of frame modules. The longitudinal bolts sequentially penetrate through pad plate limiting holes located on the same layer pad plates, front and rear holes of the corner parts at the lower ends of the corner columns in the front, front and rear holes of the corner parts at the lower ends of the corner columns in the back and pad plate limiting holes formed in the pad plates and then are connected and fixed through nuts. Interior decoration work can be completed in a factory, the structure steel amount is obviously reduced, and meanwhile members are light and convenient, so that the multi-module structure is quicker to install. A lightweight steel wall can be changed according to the change of room opening requirements and building size, convenience is brought to installation of heat insulation layers and line pipelines, and the factorization degree and construction speed are high.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a multi-module structure for a 3-dimensional box-type assembled light steel structure and a connection method thereof. Background technique [0002] The traditional modular structure system mainly includes container, section steel frame and light steel keel. Each of these systems has some limitations: [0003] 1) The existing container module system adopts new or waste containers to form the main structure, the structure size is single, and the wall based on the corrugated board is not ideal in terms of lighting, ventilation and heat preservation; [0004] 2) The hot-rolled section steel system uses welding to form various components into a frame structure with a container shape. This structural system uses a large number of welding constructions, and the welding quality cannot be guaranteed. In addition, inert gases will be generated during the welding process, which will a...

Problems solved by technology

[0003] 1) The existing container module system adopts new or waste containers to form the main structure, the structure size is single, and the wall based on the corrugated board is not ideal in terms of lighting, ventilation and heat preservation;

[0004] 2) The hot-rolled section steel system uses welding to form various components into a frame structure with a container shape. This structural system uses a large number of welding constructions, and the welding quality cannot be guaranteed. In addition, inert gases will be generated during the welding process, which will affect health and pollute surroundings;

[0005] 3) Both the container and the hot-rolled section steel system have self-heavy problems, which will cause inconvenience in transportation and hoisting;

[0006] 4) The existing light steel keel system can only be transported and installed in units of components or walls, and a large amount of assembly work needs to be completed on site, and there are problems such as installation errors and construction conditions
