Point-Fixed Curtain Wall Hanging System for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current installation methods for super-high glass panels in curtain walls lack stability and safety, particularly when the glass panels exceed 5 meters in height, leading to inadequate support and potential instability.
Innovation Solution
A point-fixed curtain wall hanging system comprising pole members, support members, and hanging members that connect to rib-boards and panel-boards, distributing the load to ensure stability and safety, with support members fixed to the ceiling or floor and hanging members fastened to rib-boards and panel-boards using screws and claws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the glass panel height is increased to more than 5 meters for aesthetic purposes, then the curtain wall achieves better transparency and modern appearance, but the stability and safety of the glass panel deteriorates
Solution Approach 1:
The support structure is segmented into multiple components: hanging poles vertically positioned along the glass panel, support members connecting to the building structure, and hanging members forming a network between poles. This segmentation distributes the load of tall glass panels across multiple discrete support points rather than relying on a single continuous support, thereby maintaining stability while accommodating increased panel height
Solution Approach 2:
The support system transitions from traditional single-plane support to a three-dimensional spatial configuration. Hanging poles are positioned at multiple vertical locations, support members extend horizontally to building structures, and hanging members create diagonal bracing between poles. This multi-dimensional arrangement provides redundant load paths and enhances stability for super-high glass panels
2Ease of manufacture
If traditional installation methods using bottom slots and single-point claw fastening are used, then the installation process is simple, but the load bearing capacity and stability deteriorate for high glass panels
Solution Approach 1:
Multiple support functions are merged into an integrated system. The hanging poles serve as vertical supports, support members provide horizontal anchoring to the building structure, and hanging members create diagonal bracing. This combination of multiple support elements working together significantly increases load bearing capacity compared to single-point fastening, while maintaining relative installation simplicity through standardized components
Solution Approach 2:
The hanging poles and support members are pre-positioned and secured to the building structure before the glass panels are installed. This preliminary action creates a stable framework that is ready to receive and support the glass panels, ensuring proper alignment and immediate load distribution upon panel installation

AI summary
A point-fixed curtain wall hanging system comprises: a plurality of pole members, being long straight poles and connected to each other to form a plurality of hanging poles fixed vertically on the portions of a building close to a rib-board or a panel-board of a curtain wall; a plurality of support members fixed on the top portions of said hanging poles and fastened on a curtain wall support structure; and a plurality of hanging members fixed between two said pole members and connecting said pole members to each other to form said hanging poles. Due to adopting the above structure, and adopting the hanging system described in the present invention to install the glass curtain wall, the panel-board and the rib-board are both hanged to form the curtain wall and bear the pull force, more satisfying the theory of the optimization of the mechanics and meeting the requirements for the safety and the stability.
