Problems solved by technology
However, this system has the following disadvantages: the thermal insulation performance is poor, and it is necessary to set up a separate thermal insulation structure layer in cold regions; since the horizontal tie steel belt is arranged on the outside of the wall, the buckling resistance is insufficient, and additional plastering is required for the steel belt. The protection of the wall leads to the decline of the anti-seismic performance of the wall and the complicated process. It is urgent to develop a low-cost light steel skeleton foamed cement wall that integrates load-bearing, heat preservation and heat insulation.

Embodiment Construction
[0025] The present invention will be further described below in combination with the accompanying drawings and specific embodiments.
[0026] Such as Figure 1-6 As shown, a cold-formed thin-walled skeleton foam cement wall reinforced by embedded steel mesh, including upper composite keel 1, side composite keel 2, middle composite keel 3, steel wire mesh sheet 4, insulation board 5, template 6, Square thin-walled steel pipe 8, L-shaped steel 9, U-shaped steel Ⅰ10, steel sheet 11, lower composite keel 12, U-shaped steel Ⅱ13, U-shaped steel Ⅲ14, and foamed cement 15.
[0027] The upper keel 1 is composed of two U-shaped steel Ⅲ14 with the same size and three grouting holes connected by steel sheet 11. The steel sheet 11 and U-shaped steel Ⅲ14 are connected by self-tapping screws, and the connection parts are respectively located on the upper keel 1. The connection with the middle composite keel 3, the connection between the upper composite keel 1 and the side composite keel 2. ...

The invention relates to a reinforced cold-formed thin-wall skeleton foam cement wall embedded with steel mesh sheets, which belongs to the technical field of construction engineering. The present invention includes upper combined keel, side combined keel, middle combined keel, steel wire mesh sheet, heat preservation board, template, square thin-walled steel pipe, L-shaped steel, U-shaped steel I, steel sheet, lower combined keel, U-shaped steel II, and U-shaped steel III , Foamed cement. In the present invention, by combining the construction method of pre-cold-bent thin-walled steel frame and cast-in-place wall, the thermal insulation board and lateral force-resistant steel wire mesh are embedded in the wall, which can improve the thermal insulation performance of the foamed cement wall with light steel frame, Improve construction speed and reduce material consumption. The light steel skeleton, foamed cement wall and lateral force-resistant steel wire mesh work together to optimize the mechanical properties of the wall.
Description
technical field [0001] The invention relates to a reinforced cold-formed thin-wall skeleton foam cement wall embedded with steel mesh sheets, which is suitable for low-rise prefabricated buildings and belongs to the technical field of construction engineering. Background technique [0002] The light steel and light concrete structure is a new structural system made of light steel keel as the skeleton and light concrete cast-in-place. It has the construction characteristics of semi-fabricated and semi-cast-in-place, as well as the advantages of light weight, high strength, high degree of industrialization, and short construction period. . Compared with the light steel structure system, the integrity is better, and the wallboard has no sense of cavity. However, this system has the following disadvantages: the thermal insulation performance is poor, and it is necessary to set up a separate thermal insulation structure layer in cold regions; since the horizontal tie steel belt ...
