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

Abstract

The invention discloses a modular assembly type L-shaped cold-formed thin-walled steel combined wall and a connecting mode of the modular assembly type L-shaped cold-formed thin-walled steel combined wall. The modular assembly type L-shaped cold-formed thin-walled steel combined wall is characterized in that the middle part of an L-shaped cold-formed thin-walled steel framework is filled with a heat preservation layer; a wall panel and the L-shaped cold-formed thin-walled steel framework are connected through self-tapping screws; the modular assembly type L-shaped cold-formed thin-walled steel combined wall is formed by the L-shaped cold-formed thin-walled steel framework, the heat preservation layer and the wall panel. Horizontal-direction connection between an L-shaped cold-formed thin-walled steel combined wall module and a common wall module is realized through a horizontal connecting mode between wall modules; vertical-direction connection between two adjacent L-shaped cold-formed thin-walled steel combined wall modules which are adjacent in the vertical direction is realized through a vertical connecting mode between the wall modules. The modular assembly type L-shaped cold-formed thin-walled steel combined wall disclosed by the invention integrates structural bearing and heat preservation, and has the advantages of high integration and assembly degrees, applicability in industrial production and the like, and the problems of weak connection between a longitudinal wall and a horizontal wall, high difficulty and difficulty in handling installation seams, and the like can be solved. The connecting mode of the modular assembly type L-shaped cold-formed thin-walled steel combined wall is simple in structure and is quick and efficient, and a large amount of labor cost can be reduced.

Description

technical field [0001] The invention relates to a new type of industrially produced assembled L-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 to a combination of thermal insulation and structural An integrated L-shaped composite wall and a manufacturing method thereof, as well as a connection method between modules of the L-shaped composite wall and an installation procedure thereof. Background technique [0002] The traditional cold-formed thin-walled steel housing system is relatively mature in research at home and abroad, and there are related norms and regulations. Although the prefabricated cold-formed thin-walled steel residential system has become the development trend of my country's housing industry, but because its assembly level is still at the level of component assembly, the low level of assembly make...

Problems solved by technology

Although the prefabricated cold-formed thin-walled steel residential system has become the development trend of my country's housing industry, but because its assembly level is still at the level of component assembly, the low level of assembly makes the overall cost high, and it is difficult to promotion in our country

In order to improve the degree of assembly of the current cold-formed thin-walled steel residential system, the biggest structural problem is that the horizontal and vertical connections between the vertical and horizontal walls at the corners are difficult to realize, and the biggest problem in performance It is difficult to realize the combination wall integrating heat preservation and structure on the industrialized assembly line
