Dry-hanging joints of exterior walls of prefabricated buildings and prefabricated exterior walls with such joints

Abstract

A prefabricated exterior wall dry-hanging node of a prefabricated building exterior wall, including a pre-embedded box embedded in a prefabricated exterior wall panel, a hook seat, and a connecting bolt, the embedded box is open to the side of the hook seat The hook seat is connected and fastened with the embedded sleeve in the main body of the building through connecting bolts, and the hook seat passes through the side opening of the embedded box to support the entire prefabricated exterior wall panel. The building body includes prefabricated beams or shear walls. The invention simplifies the construction process, improves the construction progress, has no external wall panel licking bricks and decorations fall off, has good safety performance, the external wall panel and its decoration can be integrated in the factory, no need for workers to perform high-altitude decoration operations, and the external wall dry-hanging connection strength High, waterproof performance, excellent build quality.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a dry-hanging joint of an assembled building exterior wall and a prefabricated exterior wall with the joint. Background technique [0002] In current engineering buildings, bricklaying is generally used for exterior walls. After bricklaying, thermal insulation and exterior finishing work are carried out. There are many and cumbersome processes. At the same time, after a long time, paint such as brick licking on the exterior surface will fall off. , Masonry cannot solve the common problem of rainwater infiltrating into the room, which brings great troubles to the daily life of the majority of residents. This situation originates from the construction technology, structure and building materials; secondly, the prefabricated shear wall currently being implemented Its main core technology is the use of sleeve connection technology. This technology has ver...

[0002] In current engineering buildings, bricklaying is generally used for exterior walls. After bricklaying, thermal insulation and exterior finishing work are carried out. There are many and cumbersome processes. At the same time, after a long time, paint such as brick licking on the exterior surface will fall off. , Masonry cannot solve the common problem of rainwater infiltrating into the room, which brings great troubles to the daily life of the majority of residents. This situation originates from the construction technology, structure and building materials; secondly, the prefabricated shear wall currently being implemented Its main core technology is the use of sleeve connection technology. This technology has very strict requirements on the error between the sleeve and the steel bar, and the error is controlled within 2mm. In actual construction, it is very difficult to meet this construction process requirement, such as the sleeve It is also difficult to ensure the effective position of the steel bars connected by the sleeve when connecting with pre-embedded steel bars, which affects the structural safety of the building
