Back-bolt self-locking dry-hanging connector for stone curtain wall

Abstract

The invention provides a back-bolt type self-locking dry-hang connector for stone curtain walls. The back-bolt type self-locking dry-hang connector comprises a back bolt and a bolt lock. The back bolt comprises a clamping portion, the bolt lock comprises a protective frame and an openable clamping fitting mechanism, the clamping fitting mechanism is positioned in the protective frame and comprises an upper lip, a lower lip and two rotary shafts, the U-shaped upper lip is rotationally connected with the protective frame by one rotary shaft, hooks which are fittingly connected with the clamping portion are respectively arranged at two ends of the upper lip, the U-shaped lower lip is rotationally connected with the protective frame by the other rotary shaft, and hooks which are fittingly connected with the clamping portion are respectively arranged at two ends of the lower lip. The back-bolt type self-locking dry-hang connector has the advantages that the back bolt of the connector is embedded in the back of a dry-hang plate and is connected with the bolt lock in an insertion manner, so that workers can directly operate the back-bolt type self-locking dry-hang connector from exterior facades of the curtain walls when mounting the plate, the back-bolt type self-locking dry-hang connector is quite convenient when mounted, and single-plate replacing and repairing procedures can be greatly simplified; the back bolt can be connected with keels or anchor bolts in a fastened manner 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 type self-locking dry-hanging connector for a stone 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,...
