Adjustable Connection Node Structure and Construction Method of Prefabricated External Wall Hanging Panel

Abstract

The invention relates to an adjustable connecting node structure of a prefabricated outer wall hanging plate and a construction method of the adjustable connecting node structure. The adjustable connecting node structure comprises a first threaded connecting piece fixedly connected with a building structure; a second threaded connecting piece in threaded connection with the first threaded connecting piece, wherein the second threaded connecting piece is provided with at least one threaded structure which is not screwed; a connecting plate fixedly connected with the second threaded connecting piece and provided with a strip-shaped groove which is vertically arranged; a first threaded fastener embedded in the prefabricated outer wall hanging plate; and a second threaded fastener configured to penetrate through the strip-shaped groove and in threaded connection with the first threaded fastener. In this way, the installation of the prefabricated outer wall hanging plate is completed. The connecting node structure provided by the invention has high installation error adaptability and also has the multi-direction adjusting function. The coordinative deformation of the prefabricated outerwall hanging plate and the building structure under the action of the earthquake is ensured. The influence on the building structure is reduced.

Description

technical field [0001] The invention relates to the field of building construction engineering, in particular to an adjustable connection node structure of a prefabricated exterior wall hanging board and a construction method thereof. Background technique [0002] Prefabricated external wall hanging panels (hereinafter referred to as external hanging panels) are an important form of prefabricated enclosure structure, mainly used in frame structures. Decorative integrated concrete composite external panels, etc. In the design of the external hanging board, connecting nodes is one of the most critical contents. The main connection nodes between the external hanging panels and the main structure are divided into point-supported and line-supported. At present, line-supported connection nodes are used in some areas of my country, while point-supported connection nodes are used in the United States, Japan and Taiwan. more. In contrast, line-supported joints generally require pos...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the defects of the prior art, provide an adjustable connection node structure and construction method of prefabricated external wall hanging panels, and solve the problem of insufficient coordinated deformation ability of the existing point-supported connection nodes during earthquakes. Problems such as easy damage to joints or concrete, failure to adapt to installation errors and difficulties in installation
