Prefabricated external wall template structure system with heat insulation function, and construction method thereof

Abstract

The invention discloses a prefabricated external wall template structure system with a heat insulation function, and a construction method thereof. The prefabricated external wall template structure system with the heat insulation function comprises a prefabricated concrete external wall template. A heat insulation layer is fixed at inside of the prefabricated concrete external wall template. A cast-in-situ shear wall is poured at inside of the heat insulation layer. The cast-in-situ shear wall is obtained through field pouring in a manner that the prefabricated concrete external wall template and an inner template which is vertically arranged at inside of the prefabricated concrete external wall template are used as supports; and wall body reinforcing bars are bond in the cast-in-situ shear wall. Compared with the prior art, the prefabricated external wall template structure system and the construction method are advantageous in that the heat insulation layer is combined with the prefabricated concrete external wall template, thereby saving secondary construction of the heat insulation layer; the heat insulation layer is arranged at inside part of the prefabricated concrete external wall template, so that the service life of the heat insulation layer is same with that of the body structure, thereby improving durability of the heat insulation layer, improving heat insulation performance of a building wall and improving construction quality. According to the prefabricated external wall template structure system, a construction external template and an external scaffold can be saved, thereby improving construction efficiency.

Description
