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

Abstract

The invention provides a modularized assembling-type cross-shaped cold-bending thin-wall profile steel combined wall and a connection method thereof. A cross-shaped cold bending thin-wall steel framework is filled with a thermal insulation layer. A wall face board and a cross-shaped cold bending thin-wall steel keel are connected together through tapping screws. The cross-shaped cold bending thin-wall steel framework, the thermal insulation layer and the wall face board form the modularized assembling-type cross-shaped cold-bending thin-wall profile steel combined wall. The cross-shaped cold-bending thin-wall profile steel combined wall and a common wall module are in horizontal connection realized through an inter-wall-module horizontal connection method. An upper cross-shaped cold-bending thin-wall profile steel combined wall and a lower cross-shaped cold-bending thin-wall profile steel combined wall are in vertical connection realized through an inter-wall-module vertical connection method. The modularized assembling-type cross-shaped cold-bending thin-wall profile steel combined wall integrates functions of structural load bearing and thermal insulation and has advantages of being high in integration and assembly degree and being suitable for industrial production and the like. Problems that field assembly and connection of joints of walls whose four faces are perpendicular to each other is poor in strength, high in difficulty and the mounting joints are difficult to process.

Description

technical field [0001] The invention relates to a new type of industrially produced assembled cross-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 cross-shaped composite wall and a manufacturing method thereof, as well as a connection method between modules of the cross-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 a...

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 problem in terms of structure is that the horizontal connection and vertical connection at the junction of the three perpendicular walls are difficult to realize. The biggest problem in terms of performance is the integration of heat preservation, structure An integrated composite wall is difficult to realize on an industrialized assembly line
