In order to improve the construction efficiency, some construction units use composite insulation batten to replace various blocks. However, whether the block or the insulation batten can not meet the needs of the frame building owner when used as an outer wall because of its low structural strength.

The light steel skeleton can be conveniently connected with the steel structure main body component and connected with the artificial stone plate and the double-layer gypsum plate to form a stable space structure, which can bear the wind load pressure and impact load outside the wall plane and provide firm support for the outer wall system. In the patent technical solution, the outer plate of the outer wall board adopts a dry hanging mode of a curtain wall, and the flexible caulking material is filled between the outer plate blocks and between the outer plate blocks and the connecting pieces, which can absorb the deformation between the outer plate blocks and between the outer plate blocks and the light steel skeleton, and reduce the generation of cracks. However, like the existing fabricated wall board, it often uses a single-layer structure of the skeleton, and in order to increase the thickness of the insulation layer, the width of the U-shaped skeleton needs to be increased, which inevitably increases the weight of the wall board, and the continuous skeleton also forms a heat conduction bridge, affecting the heat preservation performance of the wall board.

[0004] Therefore, it is necessary to develop a new type of fabricated steel skeleton composite heat preservation wall board to solve the above problems. UTILITY MODEL CONTENT
