Keel connecting device for suspension type curtain wall

Abstract

The invention discloses a keel connecting device for a suspension type curtain wall, which comprises a connecting piece body; a horizontal keel carrying part arranged on the connecting piece body; and a baffle plate, which is used for preventing a horizontal keel from falling off from the front end of the horizontal keel carrying part, arranged on the connecting piece body. The keel connecting device provided by the invention has the advantages of being simple in structure, high in safety, high in installation efficiency and the like.

Description

technical field [0001] The invention relates to a building curtain wall system, in particular to a keel connection device for a suspended curtain wall. Background technique [0002] The curtain wall is the outer wall enclosure of the building and is not load-bearing. It is a light-weight wall with a decorative effect commonly used in modern large-scale and high-rise buildings. [0003] The existing curtain wall generally installs keels on the building wall first, and then installs curtain wall panels on the keels. At present, in order to facilitate the installation of curtain wall panels, it is usually required that the outside of the main keel and the auxiliary keel be on the same plane. Therefore, when installing the keel Generally, a corner code is used to connect the main keel (keel arranged vertically) and the fasteners embedded in the building wall, and then connect the auxiliary keel (keel arranged horizontally) between two adjacent main keels. The keel and the main ...

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 outside of the horizontal keel and the vertical keel to be on the same plane, and the horizontal keel does not need to be cut into multiple sections. Some practitioners have designed a connecting device, which connects the wall and the vertical A supporting part that can support the horizontal keel is added to the connecting piece of the keel, so that when installing the horizontal keel, the connecting pieces will be leveled first, and then the horizontal keel can be placed directly on the connecting piece on the same grid line However, the cross keel is easy to fall from the front end of the supporting part before it is fastened on the supporting part, and there is a safety risk
