Cast-in-place concrete built-in thermal insulation wall structure

Abstract

The invention relates to the field of building construction, and solves the problem of low thermal insulation performance of a concrete wall body caused by the fact that through holes for a connectingpiece and a split bolt to penetrate through are formed in a thermal insulation layer of the concrete wall body in the prior art. A cast-in-place concrete built-in thermal insulation wall structure comprises an inner wall layer, an outer wall layer, a thermal insulation layer located between the inner wall layer and the outer wall layer and a pipe body penetrating through the inner wall layer, thethermal insulation layer and the outer wall layer, an axial channel of the pipe body penetrates through the pipe body to form openings in the two ends of the pipe body, a first limiting piece and a second limiting piece are arranged on the outer side wall, and the thermal insulation layer is located between the first limiting piece and the second limiting piece. The split bolt penetrates throughthe pipe body to fasten an inner template and an outer template, and the tension of the split bolt and the supporting force of the connecting piece act synergistically to position the inner template and the outer template. Through holes cannot be formed in the cast-in-place concrete built-in thermal insulation wall structure due to the fact that split bolts are arranged, the number of the throughholes in the cast-in-place concrete built-in thermal insulation wall is reduced, heat loss is reduced, and the thermal insulation performance of the wall is improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a cast-in-situ concrete built-in thermal insulation wall structure and a construction method. Background technique [0002] The structure of the cast-in-place concrete built-in thermal insulation wall is inner wall layer-insulation layer-external wall layer, and multiple connectors are arranged on the insulation layer. The rod body of the connector of the existing cast-in-situ concrete built-in thermal insulation wall is a solid rod. In addition, the inner and outer wall layers of the cast-in-situ concrete built-in thermal insulation wall need to be fastened with tension bolts before the inner and outer formworks are poured, so that the tension of the tension bolts and the supporting force of the connectors work together to integrate the inner and outer forms. Outer template positioning. In order to allow the pull bolts to pass through, special through holes need to be prov...
