Suspended Scaffold Eaves Mounting Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for mounting scaffolds on high-rise buildings require extensive setup along the entire facade for roof repairs, which is time-consuming and costly, and do not efficiently utilize the eaves area for scaffold placement.
Innovation Solution
A suspended working scaffold is mounted along the eaves by attaching separate scaffolds with hinge joints and coupling catwalks between them, allowing for rapid and economical setup and disassembly, with adjustable stands and protective rail systems for stability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a scaffold is constructed along the entire facade from the ground for roof repairs, then safety is ensured, but the setup is time-consuming and costly
Solution Approach 1:
The scaffold system is divided into multiple separate suspended scaffold units that can be independently mounted on the roof eaves. Each unit consists of a support unit with stands, catwalk, and protective railing, fastened to the roof structure. These segmented units are then coupled together to form a continuous working platform, enabling rapid deployment without constructing a single large ground-based scaffold.
Solution Approach 2:
The invention transitions from ground-based scaffold construction to roof-mounted suspended scaffolds. By mounting the scaffolds from the roof eaves and swinging them down to the working position, the system eliminates the need for extensive ground-based assembly, significantly reducing setup time while maintaining safety through proper roof anchoring and protective railings.
2Area of stationary object
If a scaffold is constructed along the entire facade from the ground, then complete coverage is achieved, but the cost increases
Solution Approach 1:
The continuous scaffold coverage is achieved by coupling multiple identical, modular suspended scaffold units together. Each unit is a self-contained module with support unit, stands, catwalk, and protective railing that can be independently manufactured and then assembled on-site, reducing overall cost compared to a single custom-built ground scaffold.
Solution Approach 2:
The suspended scaffold units are designed as universal, multi-functional modules that can be used for various roof repair tasks. Each unit provides catwalk for worker access, protective railing for safety, and can be positioned at different locations along the eaves, making them adaptable to different building configurations and repair needs.
3Productivity
If separate scaffolds are mounted on the roof and swung past the eaves, then rapid deployment is achieved, but the complexity of mounting increases
Solution Approach 1:
The support units are pre-assembled on the roof with hinge joints and fastening mechanisms prepared in advance. The stands are pre-attached to the support units with coupling mechanisms ready, allowing the entire scaffold unit to be quickly swung down to the working position and locked into place without complex on-site assembly procedures.
4Area of stationary object
If catwalks are coupled between separate scaffolds to form a continuous catwalk, then a complete working platform is obtained, but the number of components increases
Solution Approach 1:
The continuous catwalk is formed by coupling multiple identical modular catwalk sections together. Each catwalk section is a standardized component that attaches to the stands of adjacent scaffold units, creating a continuous walking surface. This modular approach allows the catwalk to be assembled from discrete, manageable components rather than requiring a single large custom-built structure.

Implementation Method 1
A bar 20 is fastened by a hinge joint 21 in fastener 14 and it has a vertical part 22 which supports the stand 18

AI summary
A suspended working scaffold is mounted along the eaves (12) of a roof by mounting and fastening a number of separate scaffolds on the roof with hinge joints (21) and swinging them past the eaves. Then, catwalks (37) are coupled between the catwalks (13) of the scaffolds in such a manner that a continuous catwalk is obtained along the eaves.
