Rear concrete thermal curtain wall connecting piece and construction method

Abstract

The invention discloses a rear concrete thermal curtain wall connecting piece and a construction method. The connecting piece comprises a pre-buried supporting base and a connection rod, the pre-buried supporting base comprises a connector and connection steel ribs, and the connector is fixed to a surface layer steel rib of a main body concrete structure through the connection steel ribs; the tail end of the connector is pre-buried in the main body concrete structure, and the open end of the connector is attached to the inner surface of a formwork of the main body concrete structure; an internal thread is disposed on the inner wall of the connector, the outer wall of one end of the connection rod is provided with an external thread matched with the inner thread, and a through hole is formed in the other end of the connection rod. The pre-buried portion and the connection portion of the connecting piece are of a split structure, the pre-buried supporting base is buried in the main body concrete structure, the formwork for main body concrete construction is not damaged, and loss of the formwork is avoided; the connection rod and the pre-buried supporting base are fixedly installed together through the threads, and the connecting piece is higher in standardization degree, safer, more reliable and firmer in structure. The construction method is safer, quicker to implement and higher in efficiency.

Description

technical field [0001] The invention relates to the technical field of concrete thermal insulation curtain wall construction, in particular to a post-mounted concrete thermal insulation curtain wall connector and a construction method. Background technique [0002] Concrete thermal insulation curtain wall is composed of concrete surface layer and thermal insulation board, and does not bear the load and function of the main structure. It includes the cast-in-place concrete thermal insulation curtain wall and the rear concrete thermal insulation curtain wall. The post-installed concrete thermal insulation curtain wall refers to the concrete thermal insulation curtain wall that is constructed after the construction of the main structure or building enclosure wall is completed. The construction of the rear concrete thermal insulation curtain wall is carried out separately from the construction of the main structure, which reduces the possibility of construction interference and ...

AI Technical Summary

Problems solved by technology

There are following defects in this connection method: 1. When the main concrete structure is poured, some pre-embedded connectors need to penetrate the concrete formwork, which will accelerate the damage of the concrete formwork and increase the construction cost, such as Chinese utility model patent specification CN203977590U The connection method in the built-in insulation concrete structure disclosed in

2. In order to prevent the pre-embedded connectors from penetrating through the concrete formwork during the construction of the main concrete structure, the embedded parts whose length does not exceed the width of the main structure are reserved first during the construction of the main concrete structure. Welding connectors, in this construction method, leaving connectors does not need to penetrate the concrete formwork, but welding operations must be carried out during the construction of the insulation layer, but welding operations have great safety hazards, which violates the safety of building insulation engineering construction guideline
