Construction method of PCF plate provided with thermal insulation connection pieces

Abstract

The invention discloses a building construction method. A construction method of a PCF plate provided with thermal insulation connection pieces comprises the following steps: installing an external wall steel reinforcement mesh in a prefabricated die; installing the thermal insulation connection pieces, concretely, the multiple thermal insulation connection pieces are arranged on the external wall steel reinforcement mesh, the thermal insulation connection pieces are arranged to be perpendicular to the steel reinforcement mesh plane, and multiple steel reinforcements penetrate through steel reinforcement connection holes in the thermal insulation connection pieces and fixed to the external wall steel reinforcement mesh; casting external wall concrete; paving a thermal insulation layer; and performing demoulding on the external wall, and installing the external wall provided with the thermal insulation layer and an inner wall in a combining way. According to the method, the novel thermal insulation connection piece structure is adopted, and the steel reinforcements which penetrate through the steel reinforcement connection holes in the thermal insulation connection pieces are connected with the steel reinforcement mesh, thus the whole-plane connection way is formed, the traditional point connection way is changed, the load on the plane of the prefabricated external wall board can be borne, the structure is stable and reliable, the forming quality of the PCF plate is improved, and the use safety is guaranteed.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method of a PCF board with thermal insulation connecting pieces. Background technique [0002] With the advancement of building construction technology and the improvement of people's requirements for living and living environments, the requirements for wall insulation are becoming more and more stringent. Composed of sandwich insulation layer and exterior finish layer, the exterior wall insulation of this structure has the following advantages: effective protection for the inner wall and insulation materials, good insulation effect, which is much better than interior wall insulation, and the selection of insulation materials The requirements are not high, and the cost is saved; the requirements for the construction season and construction conditions are not very high, and the winter construction will not be affected. However, this sandwich insulation wall structu...

AI Technical Summary

Problems solved by technology

[0004] And the prefabricated exterior wall panels (PCF panels) developed by modern building construction technology, the connection quality between them and the inner concrete layer of the wall is related to the quality, safety, appearance and living comfort of the entire wall. When an insulation layer is set between the inner and outer walls to form a sandwich insulation wall structure, it is easy to cause inconsistent deformation of the inner and outer walls, especially the deformation of the outer wall due to temperature, humidity and concrete shrinkage is difficult to control
