A modular cold-formed thin-walled steel composite wall and its connection method

Abstract

Provided are a modular cold-bent thin-wall type steel combined wall and a connection method thereof. The space between a cold-bent thin-wall type steel framework and an opened cold-bent thin-wall type steel framework is filled with a heat preservation layer. A wall panel and a cold-bent thin-wall type steel keel are connected through self-tapping screws. The cold-bent thin-wall type steel framework, the opened cold-bent thin-wall type steel framework, the heat preservation layer and the wall panel form the modular cold-bent thin-wall type steel combined wall. The horizontal-direction connection of every two cold-bent thin-wall type steel combined wall modules adjacent left and right is achieved by horizontally connecting the wall modules. The vertical-direction connection of every two cold-bent thin-wall type steel combined wall modules adjacent up and down is achieved by vertically connecting the wall modules. The modular cold-bent thin-wall type steel combined wall integrates the functions of structure load bearing, heat preservation and window integration, the integration degree is high, assembly is rapid and efficient, the material cost is low, the labor cost is greatly reduced, the structure is simple, and the modular cold-bent thin-wall type steel combined wall is suitable for industrial production.

Description

technical field [0001] The invention relates to an industrially produced cold-formed thin-walled steel composite wall module, a hole-shaped cold-formed thin-walled steel composite wall module and the horizontal and vertical connection methods between the wall modules, belonging to the technical field of structural engineering, in particular It refers to a composite wall integrating heat preservation, structure and windows and its production and manufacturing method, as well as the connection mode and installation process between the modules of the composite wall. Background technique [0002] In the field of steel structures at home and abroad, the walls suitable for low and multi-storey prefabricated buildings are mainly divided into wood panel walls, prefabricated reinforced concrete shear walls, steel plate shear walls, and cold-formed thin-walled steel concrete shear walls. At home and abroad, there are many examples of successfully using the above walls to form building...

AI Technical Summary

Problems solved by technology

However, at present, the degree of assembly of most prefabricated walls at home and abroad is still at the component level, and there is still a certain gap in the modular design, modular production, modular transportation, and modular installation of the overall wall, especially There is still a lot of room for development in the prefabricated wall with thermal insulation and structural integration

Due to the low degree of modular assembly of the current prefabricated wall, a large amount of labor costs are required for processing and installation, resulting in high cost of the wall, which in turn increases the cost of the overall building
