Dry-hang joint for external wall of fabricated building and prefabricated external wall with dry-hang joint

Abstract

The invention provides a dry-hang joint for an external wall of a fabricated building and a prefabricated external wall with the dry-hang joint. The dry-hang joint comprises a pre-buried box, a hook seat and a connecting bolt which are pre-buried in a prefabricated external wall board, wherein the side surface, facing the hook seat, of the pre-buried box is open; the hook seat is connected and fastened with a pre-buried sleeve in a building main body through the connecting bolt; the hook seat penetrates through the opening in the side surface of the pre-buried box, so as to support the whole prefabricated external wall board; the building main body comprises a prefabricated beam or a shear wall. The dry-hang joint and the prefabricated external wall have the advantages that the construction procedures are simplified; the construction progress is improved; lick bricks and decorations are prevented from flaking off from the external wall board, so that the safety performance is high; the external wall board and the decorations of the external wall board can be produced integrally in a factory, so that high-altitude decoration operation of a worker is avoided; the dry-hang bonding strength of the external wall is high; the water resistance is good; the building quality is excellent.

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.

[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
