A modular assembly type T-shaped cold-formed thin-walled steel composite wall connection method

Abstract

The invention discloses a modular assembly type T-shaped cold-formed thin-walled steel combined wall and a connecting mode of the modular assembly type T-shaped cold-formed thin-walled steel combined wall. The modular assembly type T-shaped cold-formed thin-walled steel combined wall is characterized in that the middle part of a T-shaped cold-formed thin-walled steel framework is filled with a heat preservation layer; a wall panel and the T-shaped cold-formed thin-walled steel framework are connected through self-tapping screws; the modular assembly type T-shaped cold-formed thin-walled steel combined wall is formed by the T-shaped cold-formed thin-walled steel framework, the heat preservation layer and the wall panel. Horizontal-direction connection between a T-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 T-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 T-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 field assembly and connection in a wall connecting position of three walls which are vertical to each other, high difficulty and difficulty in handling installation seams, and the like can be solved. The connecting mode of the modular assembly type T-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 T-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 T-shaped composite wall and a manufacturing method thereof, as well as a connection method between modules of the T-shaped composite wall and an installation process thereof. Background technique [0002] The traditional cold-formed thin-walled steel residential system is relatively mature in research at home and abroad, and there are related norms and regulations. However, there are not many quantitative studies on the joint parts of the wall in China at present, and a unified joint design standard cannot be formed. Its safety performance needs further study.

[0002] The traditional cold-formed thin-walled steel residential system is relatively mature in research at home and abroad, and there are related norms and regulations. However, there are not many quantitative studies on the joint parts of the wall in China at present, and a unified joint design standard cannot be formed. Its safety performance needs to be further studied

Although the prefabricated cold-formed thin-walled steel wall panel structure system has become the development trend of my country's housing industry today, but at present, its assembly level is still at the level of component assembly, and the assembly level is low, making the overall cost high. Difficult to promote in our country

In order to improve the degree of assembly of the current cold-formed thin-walled steel wall panel structural system, the biggest problem in terms of structure is that the horizontal connection and vertical connection at the junction of three mutually perpendicular walls are difficult to realize. The biggest problem in terms of performance is the integration of thermal insulation , structurally integrated composite walls are difficult to realize on industrialized assembly lines
