Technical Field

[0001] This utility model relates to the field of light steel frame houses, and in particular to a high-efficiency thermal insulation composite wall structure for light steel frame houses. Background Technology

[0002] Light steel frame houses have a multi-layered composite structure in their walls, which ensures the insulation of the walls. However, due to the built-in steel metal frame, heat is transferred quickly at the built-in frame, resulting in temperature differences in the walls. In addition, the internal foam interlayer is difficult to fill fully. Utility Model Content

[0003] The purpose of this utility model is to provide a high-efficiency thermal insulation composite wall structure for light steel houses to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A high-efficiency thermal insulation composite wall structure for light steel houses includes an inner wall panel, a C-shaped light steel frame, thermal insulation connecting strips, a polyurethane foam layer, a structural panel, filling holes, moisture-proof breathable paper, steel wire reinforcement mesh, and an outer decorative layer. Several C-shaped light steel frames are equidistantly installed on the outer side of the inner wall panel. Each C-shaped light steel frame has matching C-shaped light steel frames installed inside it via thermal insulation connecting strips. A structural panel is installed on the outer side of the outer C-shaped light steel frames, and filling holes are equidistantly opened on the structural panel. The polyurethane foam layer between the inner wall panel and the structural panel is filled through these filling holes. Moisture-proof breathable paper is adhered to the outer side of the structural panel. A steel wire reinforcement mesh is laid on the outer surface of the moisture-proof breathable paper, and an outer decorative layer is installed on the outer side of the steel wire reinforcement mesh.

[0006] Preferably, the high-efficiency thermal insulation composite wall structure of the light steel house also includes slots, blocks, and connecting bolts. Several slots are equally spaced on both sides of the C-shaped light steel frame. The front and rear ends of the thermal insulation connecting strip are integrally formed with blocks that match the slots. The thermal insulation connecting strip is connected and fixed to the slots on the front and rear ends of the C-shaped light steel frame through the blocks on both sides. The inner sides of the front and rear C-shaped light steel frames are connected to the front inner wall panel and the rear structural panel through connecting bolts.

[0007] The beneficial effects of this utility model are: the utility model is reasonably designed, the multi-layer composite structure can ensure the thermal insulation of the wall, and the internal light steel frame is connected by heat insulation strips to cut off the heat conduction through the internal steel metal frame, avoiding large temperature differences at the connection of the internal frame in the wall. In addition, the polyurethane foam layer is fully filled through the filling holes on the structural layer during the production process. Attached Figure Description

Several C-shaped light steel frames 2 are equidistantly installed on the outer side of the inner wall panel 1. Each C-shaped light steel frame 2 has matching C-shaped light steel frames 2 installed inside it via thermal insulation connecting strips 3. A structural panel 5 is installed on the outer side of the outer C-shaped light steel frames 2, and filling holes 6 are equidistantly opened on the structural panel 5.
