AI Technical Summary

Technical Problem

Conventional curtain walls have limited angle adjustment capabilities due to the design of vertical connecting members that restrict the movement of adjacent curtain wall units, resulting in a small and restricted range of angle adjustment.

Method used

The curtain wall design incorporates an intermediate material with arc-shaped wall portions fixed to opposing vertical frames, allowing for greater angle adjustment by moving the curtain wall units along these arcs, and includes a double tight structure for airtightness and watertightness.

Benefits of technology

The design enables a larger range of angle adjustment between adjacent curtain wall units while maintaining airtightness and watertightness, simplifying the vertical frame structure and reducing costs by using identical materials for the frames.

Abstract

This provides a curtain wall with a greater range of angle adjustment between adjacent curtain wall units. [Solution] A curtain wall that can be installed by changing the angle between two adjacent curtain wall units, comprising two different curtain wall units arranged between opposing vertical frames in the installed state, with an intermediate member fixed to one of the opposing vertical frames, the intermediate member having an arc-shaped wall portion that bulges outward towards the outside with a virtual point located between the opposing vertical frames as the center, and each vertical frame having a tight member that abuts against the arc-shaped wall portion when the two curtain wall units are installed.
