Keel connecting device based on suspended curtain wall

Abstract

The invention discloses a keel connecting device based on a suspended curtain wall, which comprises a connecting piece body, wherein the connecting piece body is provided with a vertical keel containing part, and a horizontal keel bearing table is arranged at the front end of the vertical keel containing part. The keel connecting device based on the suspended curtain wall has the advantage of simple and reliable structure, can effectively improve the keel installation efficiency, and can eliminate the potential safety hazards caused by keel installation.

Description

technical field [0001] The invention relates to a building curtain wall system, in particular to a keel connecting device based on a hanging curtain wall. Background technique [0002] Curtain wall is the outer wall of the building, it is not load-bearing, it is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. [0003] In the existing curtain wall, the keel is generally installed on the building wall first, and then the curtain wall board is installed on the keel. At present, in order to facilitate the installation of the curtain wall board, the main keel and the outside of the auxiliary keel are usually required to be on the same plane. Therefore, when installing the keel Generally, a corner code is used to connect the main keel (vertical keel) and the fasteners embedded on the building wall, and then connect the auxiliary keel (horizontal keel) between the adjacent two main keels. The keel and the main keel are connected by ...

AI Technical Summary

Problems solved by technology

There are the following problems in the connection form of the curtain wall keel: 1. To make the main keel and the auxiliary keel on the same plane, the auxiliary keel must be cut into multiple sections before it can be connected to the adjacent two main keels, which causes the keel installation. The process is cumbersome; 2. The main keel and the wall, as well as the main keel and the auxiliary keel, need to be connected with different corner codes, and there are many types of accessories, which is not easy to install and manage; The code can only be connected by self-tapping screws, and the self-tapping screws need to bear the shear force, so the self-tapping screws are prone to failure, causing the curtain wall panels to fall, forming a safety hazard; 4. If the main keel is welded to the auxiliary keel, it will When washed by rainwater, the welding points are prone to rust, forming a safety hazard. When the rust water stays on the surface of the curtain wall, it will affect the overall appearance of the curtain wall and it is not easy to clean

[0004] At present, there is a frame-groove curtain wall, which does not require the sub-keel and the outside of the main keel to be on the same plane, and the sub-keel does not need to be cut into multiple sections, but the connection form of the sub-keel and the main keel still adopts the existing corner code The connection structure, or directly fixing the auxiliary keel on the vertical keel by self-tapping screws, this connection method will also leave potential safety hazards. The development bottleneck of material curtain wall technology
