Light steel assembly type composite wall board, light steel framework, manufacturing method and installing method thereof

Abstract

The invention provides a light steel assembly type composite wall board, a light steel framework, a manufacturing method and an installing method thereof. An outer side frame of the light steel framework uses M-shaped steel; the inside uses C-shaped steel; the outer side frame is connected by C-shaped connecting elements through tapping screws; the vertical and horizontal bearing force is obviously improved; the anti-shearing and load bearing effects are good; a sandwich heat simulation layer is filled into the light steel framework; the heat simulation and light steel framework deformation limitation effects are achieved; the outer maintenance plate is attached to the outer side of the light steel framework; a heat insulation layer is arranged between the outer maintenance plate and the light steel framework; the outer maintenance plate and the light steel framework are connected through tapping screws; the horizontal anti-shearing capability, anti-cracking and anti-impacting performance of the wall body are further improved; the factory wet operation is reduced; the cold and heat bridge influence is reduced; the wall board and the main board are fixed through turnbuckles and sleeves; the connection is simple and reliable. The forming components of the composite wall board have the advantages that the types are few; the dead weight is light; steel consumption is low; heat insulation and sound isolation effects are achieved; the assembled degree is high; the fast full prefabricated assembled construction can be realized; the cost is low; the light steel assembly type composite wall board is applicable to low and multi-storey building load bearing wall systems.

Description

technical field [0001] The invention belongs to the technical field of building structure engineering, and specifically relates to a light-steel assembled composite wallboard, in particular to a composite wallboard integrating heat preservation and structure and its manufacturing method and installation method. Background technique [0002] In the field of civil engineering at home and abroad, the wall panels suitable for prefabricated houses are mainly divided into wooden walls, prefabricated reinforced concrete shear walls, steel plate shear walls, cold-formed thin-walled steel composite walls, cold-formed thin-walled steel concrete shear walls wall. However, at present, the degree of assembly of most prefabricated wall panels 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 panels, especially There are still great deficiencie...

AI Technical Summary

Problems solved by technology

[0004] 1. The diagonal bracing in the light steel frame of the wall is a steel belt, but the steel belt is prone to instability when it is under pressure, and the lateral stiffness it can provide is small, resulting in weak vertical bearing capacity of the overall wall panel;

[0005] 2. There is no horizontal C-shaped steel in the light steel frame, which will cause the calculated length of the vertical C-shaped steel column to be too large. When the vertical load is applied, the C-shaped steel column is prone to local instability, which will lead to the horizontal shear resistance of the overall wall panel weak;

[0006] 3. The surface layer of the wall panel is made of self-compacting cement + steel wire mesh poured on site. The factory has relatively large wet operation, low construction efficiency, and is not environmentally friendly; the surface layer of the wall panel and the light steel keel use self-tapping screws There are thermal bridges and cold bridges between the two, which seriously affect the overall thermal insulation performance of the wall panels;

[0007] 4. The sandwich insulation layer of the wall panel is made of foamed lightweight aggregate concrete. There is wet work on site and the filling efficiency is low.

[0008] Patent 201510341160.7 discloses a light-steel composite wall panel for a prefabricated house. The disclosed connection method between the wall panel and the main board is to use the concave cross-sectional shape of the transverse M-shaped steel combined with the matching square steel pipe to form a connection through bolt fixing, but the connection The site construction method is more complicated, and the installation accuracy is extremely high, especially the connection between the wallboard and the main board can only be realized, and the rigid connection between the upper and lower two-layer wallboards cannot be guaranteed, and there is a large potential safety hazard
