A double-layer glass curtain wall

By introducing interlocking mechanisms and auxiliary support fastening mechanisms into the double-glazed curtain wall, the problem of increased bending moment and shear force at the fixed points is solved, thereby improving the stability and wind pressure resistance of the structure and reducing the risk of fatigue damage to the glass panels.

AI Technical Summary

Technical Problem

The existing double-glazed curtain wall fixing and support structure lacks external auxiliary support, which leads to a significant increase in bending moment and shear force at the fixing points of large-sized or irregularly shaped curtain wall units, threatening the overall structural safety.

Method used

It adopts an interlocking mechanism and an auxiliary support fastening mechanism, which is rigidly connected to the building body through a fixed base. Combined with the threaded connection of the interlocking plate and the locking rod, it forms a multi-level coordinated fixation, providing bidirectional rigid constraint and elastic buffer, and improving wind pressure resistance and shear resistance.

Benefits of technology

It significantly improves the wind pressure and shear resistance of double-glazed curtain walls, reduces the risk of fatigue damage to glass panels, and ensures structural stability and airtightness.

Abstract

This utility model relates to the field of building curtain wall technology and discloses a double-layer glass curtain wall, including a first glass curtain wall and a second glass curtain wall. The bottom ends of both the first and second glass curtain walls are fixedly installed with mounting bases, and the top ends of both are connected to interlocking mechanisms. An auxiliary support and fastening mechanism is installed above the interlocking mechanisms. The interlocking mechanism includes an outer locking plate and an inner locking plate, with locking pieces fixedly connected to the inner sides of both plates. The locking pieces overlap the outer surfaces of the first and second glass curtain walls. The V-shaped groove of the fixing seat of the auxiliary support and fastening mechanism contacts the threaded layer of the locking rod. Limiting bolts pass through and lock the two sets of fixing seats, converting the axial tension of the locking rod into a radial compressive force on the curtain wall, significantly improving wind pressure resistance and shear resistance.
