A connection structure for opening windows in glass curtain walls

Abstract

The invention discloses a connecting structure of a glass curtain wall opening window. The connecting structure comprises a beam and a sash frame connected with the beam through a hook connecting mechanism. The beam comprises a hook matching part. The sash frame comprises a hook. The hook matching part is circumferentially provided with a slide groove. The hook is provided with a through hole. The connecting structure further comprises an anti-disengagement block. The anti-disengagement block penetrates through the through hole, the lower portion of the anti-disengagement block is arranged in the slide groove in a sliding mode, and the upper portion of the anti-disengagement block is connected with the through hole in a clamping mode. The hook is movably connected with the hook matching part through the anti-disengagement block, the rotation of the hook around the hook matching part is not influenced, and the hook is prevented from being disengaged from the hook matching part. In addition, during negative wind pressure of the sash window, the influences on the anti-disengagement structure are small; even when the use time is long, the abrasion to the anti-disengagement structure is quite small, and therefore the anti-disengagement structure is quite firm; furthermore, the anti-disengagement structure is not limited by wall thicknesses of profiles.

Description

technical field [0001] The invention relates to the technical field of glass curtain wall engineering, in particular to a connection structure for opening windows of a glass curtain wall. Background technique [0002] In the design of open windows in glass curtain walls, the hook-type connection has the characteristics of large bearing capacity because the sash and window frame are hinged through the long axis, and can meet the use requirements of large-sized open windows. However, because the hook-type opening window adopts the installation method of direct hooking, it is easy to fall off when encountering strong wind during use, causing the opening window to fall, which has certain safety hazards. A reliable anti-falling device must be installed to ensure normal use. [0003] The usual practice is to install an anti-falling baffle above the hook connection structure, and the baffle is fixed on the aluminum alloy beam of the curtain wall with self-tapping screws. However, ...

AI Technical Summary

Problems solved by technology

However, this technical solution still has the following defects: when the negative wind pressure of the window sash is too large, the requirements for the material and structural stability of the pressing part and the pressing fitting part are very high, and as the use time increases, the pressing part and the pressing part The mating part is very easy to wear and cause damage, resulting in failure of the anti-falling function
