Hinged Support Plate for Curtain Wall Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for glass curtain walls are inefficient in assembly, cause stress concentration leading to potential damage, and compromise security due to the need for drilling holes, which reduces glass strength and increases the risk of breakage.
Innovation Solution
A fastening device comprising a first and second clamping plate, a support plate, and a hinged second support plate that allows for three-dimensional adjustment and full surface contact, reducing stress concentration and enhancing stability and security by accommodating movement caused by wind, snow, temperature changes, or earthquakes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If holes are defined on the glass curtain wall units for assembly, then the curtain wall units can be connected and assembled, but the glass strength is reduced and security problems arise due to stress concentration at the holes
Solution Approach 1:
The support function is segmented between the first support plate (providing primary support) and the second support plate (providing additional support and adjustment), allowing the system to achieve both assembly capability and stress distribution without holes in the glass
Solution Approach 2:
The fastening device acts as an intermediary component between the curtain wall units and the supporting structure, transferring loads through the clamping plates and support plates rather than through holes in the glass, thereby maintaining glass integrity while enabling assembly
2Device complexity
If a fixed support plate is used between clamping plates, then the structure is simple, but stress concentration occurs when the curtain wall moves or rotates due to wind load or shock
Solution Approach 1:
The second support plate is designed to be movable relative to the first support plate, allowing the support structure to dynamically adapt to movements and rotations of the curtain wall under wind load or shock, thereby preventing stress concentration and improving reliability
Solution Approach 2:
The relative position and orientation of the second support plate can change in response to external forces, allowing the support system to adjust its geometric parameters to maintain optimal stress distribution under varying load conditions
3Adaptability or versatility
If the contact surface between glass curtain wall and support plate becomes a line due to movement, then the fastening device accommodates movement, but stress concentration causes the glass to crack or be damaged
Solution Approach 1:
The hinged connection between the first and second support plates introduces an additional degree of freedom, allowing the support system to accommodate movement in multiple dimensions while maintaining a stable contact surface that distributes stress across an area rather than concentrating it at a line or point

AI summary
A fastening device for curtain wall units includes a first clamping plate, a second clamping plate fixed to the first clamping plate and spaced apart from the first clamping plate, a first support plate positioned between the first clamping plate and the second clamping plate, and a second support plate hinged to the first support plate and configured to support the curtain wall units.
