Back-bolt type connector for curtain walls

Abstract

The invention provides a back-bolt type connector for curtain walls. The back-bolt type connector is characterized by comprising a back bolt and a bolt lock; the back bolt comprises a clamping portion, the bolt lock comprises a protective frame and a clamping matching mechanism capable of being opened, the clamping matching mechanism is positioned in the protective frame and comprises an upper lip, a lower lip and two rotary shafts, the upper lip is rotationally connected with the protective frame by one rotary shaft and comprises a plurality of strips which are overlapped on one another, a hook which is fittingly connected with the clamping portion is arranged at the front end of each strip of the upper lip, the lower lip is rotationally connected with the protective frame by the other rotary shaft and comprises a plurality of strips which are overlapped on one another, and a hook which is fittingly connected with the clamping portion is arranged at the front end of each strip of the lower lip. The back-bolt type connector has the advantages that the back bolt of the connector is embedded in the back surface of a dry hang plate and is connected with the bolt lock in an insertion manner, and accordingly single-plate replacing and repairing procedures can be greatly simplified; the back bolt can be firmly connected with a keel or an anchor bolt as compared with the traditional back-bolt type connector.

Description

technical field [0001] The invention relates to the field of building components, in particular to a back-bolt connector for a curtain wall. Background technique [0002] Stone dry hanging method, also known as empty hanging method, is a new construction technology in contemporary stone decoration. In this method, metal pendants are used to directly hang the facing stone on the wall or on the steel frame without grouting and pasting. The principle is to set the main stress points on the main structure, and fix the stone on the building through metal pendants to form a stone curtain wall. [0003] There are mainly two types of dry-hanging curtain wall connectors (metal pendants) at present: groove connectors and back bolt connectors. Groove connectors are evolved from the earliest steel pin connectors and can be divided into short groove connectors and through groove connectors. Due to the high requirements on the thickness of the plate, the earliest steel pin connectors h...
