L-shaped light-steel frame, L-shaped light-steel assembled composite wallboard and installation method of L-shaped light-steel assembled composite wallboard

Abstract

The invention provides an L-shaped light-steel frame, an L-shaped light-steel assembled composite wallboard and an installation method thereof. The L-shaped light-steel frame serves as a connecting part for corner turning and connection of wall bodies of an assembled house, so the problems of connection structures and wall body structures are well solved. The L-shaped light-steel frame comprises a first frame and a second frame perpendicular to each other, wherein an outer frame comprises M-shaped steel and corner square steel, horizontal C-shaped steel is arranged inside, and diagonal bracings adopt C-shaped steel to improve the stability and shear resistance; the wallboard fills the light-steel frame through a sandwich insulating layer to insulate heat and prevent the light-steel frame from being deformed; the light-steel frame is added with external maintenance boards to improve the horizontal shear resistance, crack resistance and impact resistance of the wall bodies; the vertical connection between the wall bodies and mainboards is realized through turnbuckles and sleeves on the outer frame of the light-steel frame, so as to connect the wall bodies of upper and lower layers to form an integral body and reinforce the reliability of connection between the wallboards and the mainboards. According to the L-shaped light-steel frame, the L-shaped light-steel assembled composite wallboard and the installation method, the assembly level is high, the industrial production is facilitated, the functions of heat insulation and structure connection are integrated, the safety and reliability are high, the construction is facilitated, and the cost is lower.

Description

technical field [0001] The invention belongs to the technical field of building structure engineering, in particular to the field of prefabricated building structures, and particularly relates to an L-shaped light steel frame integrating heat preservation and structure, a composite wall panel and an installation method thereof. Background technique [0002] In the field of existing building technology, 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, and cold-formed thin-walled steel concrete shear walls. wall. At present, the degree of assembly of most prefabricated wall panels at home and abroad is still at the component level. Modular design, modular production, modular transportation, modular installation, light steel prefabricated composite wall panels integrating heat preservation and structure and their installation...

AI Technical Summary

Problems solved by technology

During actual use, it is found that the overall stability and lateral stiffness of the wall need to be further improved; the connection between the upper and lower walls cannot form a whole, and the connection reliability between the wall and the main board needs to be enhanced; there are a lot of wet operations, self-compacting cement+ The surface layer formed by the steel wire mesh has a complex process; the insulation performance of the sandwich insulation layer and the efficiency of the insulation material filling are low; the insulation and insulation performance between the outer guard plate and the light steel frame is insufficient
