Prefabricated thermal insulation wall corner connection reinforcing structure and construction method thereof

Abstract

The invention belongs to the technical field of prefabricated house building engineering, and particularly discloses a prefabricated thermal insulation wall corner connection reinforcing structure and a construction method thereof. The structure comprises two prefabricated thermal insulation walls which are vertically connected, an outer reinforcing back ridge, an inner formwork and an inner reinforcing back ridge, wherein the outer reinforcing back ridge, the inner formwork and the inner reinforcing back ridge are all in an L shape; the inner sides of the two sides of the outer reinforcing back ridge are connected with outer concrete layers of the two prefabricated thermal insulation walls correspondingly; the outer sides of the two sides of the inner formwork are connected with inner concrete layers of the two prefabricated thermal insulation walls correspondingly; the inner sides of the two sides of the inner formwork are connected with the outer sides of the two sides of the inner reinforcing back ridge correspondingly; the outer reinforcing back ridge is connected with the inner reinforcing back ridge in a fastened mode; a cast-in-place concrete inner wall is arranged between the extending parts of the two prefabricated thermal insulation walls and the inner formwork; and the two ends of the cast-in-place concrete inner wall are connected with the inner concrete layers of the two prefabricated thermal insulation walls correspondingly. According to the prefabricated thermal insulation wall corner connection reinforcing structure and the construction method thereof, the problem that formwork expansion is prone to occurring in the cast-in-place concrete inner wall pouring process is solved, corner connection of the two prefabricated thermal insulation walls is firmer, and construction is convenient.

Description

technical field [0001] The invention belongs to the technical field of prefabricated house construction engineering, and more specifically relates to a prefabricated thermal insulation wall corner connection reinforcement structure and a construction method thereof. Background technique [0002] Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and transported to the construction site. The buildings assembled and installed on site by reliable connection methods have the advantages of greatly reducing the on-site assembly operations compared with the original cast-in-place operations, integrated design and construction of buildings and decoration, standardized design, information management, energy saving and environmental protection, et...
