the thickness of the base concrete wall body is not less than 100mm, the thickness of the foaming cement plate is not less than 30mm, and the thickness of the cement mortar protective layer is not more than 20mm. Compared with sandwich heat-insulating wallboards commonly adopted in assembled buildings, the sandwich heat-insulating wallboard can be reduced in thickness and weight, and construction difficulty is reduced.
The heat-insulating board adopts the foaming cement board, has low heat conductivity coefficient and A-grade combustion grade, and can meet the heat-insulating requirements of summer hot and winter cold areas and improve fire resistance.
Furthermore, the connecting piece adopts an integrated anchor bolt, the shearing resistance and the pulling resistance are superior to those of a knocking anchor bolt and a screwing anchor bolt, and the requirement on the anchoring length is lower than that of a common FRP and stainless steel connecting piece.
The utility model adopts a production mode of integrating structure and heat preservation, and can improve the construction efficiency compared with a prefabricated single wallboard with heat preservation. Comprising the following steps.
Step one, supporting a mould, binding reinforcing steel bars and pouring base layer concrete.
And step two, paving an insulation board and plastering cement mortar before initial setting after the base layer concrete is poured and vibrated.
