Precast composite thermal-insulation wallboard

Abstract

The invention provides a precast composite thermal-insulation wallboard which comprises an inner wall and an outer wall, wherein a thermal-insulation layer is arranged between the inner wall and the outer wall; at least two transverse grooves and two longitudinal grooves are formed in the upper surface of the thermal-insulation layer; the transverse grooves and the longitudinal grooves are crossed; at least two transverse bulges and two longitudinal bulges are arranged on the inner surface of the inner wall; the transverse bulges and the longitudinal bulges are crossed; the transverse grooves are matched with the transverse bulges; the longitudinal grooves are matched with the longitudinal bulges; the lower surface of the thermal-insulation layer is a plane surface. The precast composite thermal-insulation wallboard provided by the invention can overcome defects in the prior art.

Description

technical field [0001] The invention relates to a building component, which is a prefabricated composite thermal insulation wallboard Background technique [0002] Due to the many advantages of thermal insulation wall panels, the construction industry is often used in construction projects. However, it is found during use that the thickness of the thermal insulation layer is generally difficult to reach more than 10 cm. When the thermal insulation layer is thickened, the safe thickness of the wall decreases, and then Reduce the safety performance of the overall wallboard; because this structure needs to be connected by metal parts, it is easy to cause cracks on the surface of the outer wall in the environment of thermal expansion and contraction, and the inner and outer wall skins will fall off after water seepage. It is necessary to penetrate the insulation layer in the manufacture of the insulation layer, leaving large pores for the insulation layer, so that the insulation...

However, it is found during use that the thickness of the thermal insulation layer is generally difficult to reach more than 10 cm. When the thermal insulation layer is thickened, the safe thickness of the wall decreases, and then Reduce the safety performance of the overall wallboard; because this structure needs to be connected by metal parts, it is easy to cause cracks on the surface of the outer wall in the environment of thermal expansion and contraction, and the inner and outer wall skins will fall off after water seepage. It is necessary to penetrate the insulation layer in the manufacture of the insulation layer, leaving large pores for the insulation layer, which greatly reduces the insulation effect
