Post Fastening Device for Double Wall Guardrails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guardrail fixing devices for double walls clutter the upper surface and restrict the support surface, making it difficult to maintain a uniform surface continuity and optimize the support area, especially during construction where safety barriers are necessary around elevated platforms.
Innovation Solution
A device comprising a sleeve with a positioning mechanism along a vertical axis and an anchoring assembly that fixes the sleeve within the double wall's thickness, allowing the guardrail posts to be mounted vertically without protruding from the surface, ensuring the upper surface remains unobstructed and allowing for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If receiving holes are arranged vertically in support elements to receive railing posts, then guardrails can be installed on the support elements, but the holes clutter the upper surface and restrict the support surface for platform installation
Solution Approach 1:
The invention extracts the post-receiving function from the upper surface of the support element by moving it to the vertical facade. The anchoring device receives the guardrail post in a recess formed in the vertical facade of the support element, not in holes on the upper surface. This separates the guardrail installation function from the platform support function, allowing both to coexist without interfering with each other's required surface areas.
2Area of stationary object
If anchoring devices are used to fix guardrail posts on vertical facades of double walls, then the support surface is optimized, but parts project from the walls and create complexity in removal while maintaining surface continuity
Solution Approach 1:
The anchoring device is segmented into distinct functional components: a support plate that contacts the inner face of the panel, an anchoring element that engages with the panel structure, and a recess that receives the post. This segmentation allows each component to be optimized independently and simplifies removal, as the entire device can be detached as a modular assembly without compromising surface continuity.
3Reliability
If guardrail posts are mounted on double walls, then safety barriers are provided around elevated platforms, but the mounting devices alter the vertical surfaces of the panels
Solution Approach 1:
The invention applies local quality by concentrating the mounting function in a localized recess on the vertical facade, rather than altering the entire panel surface. The support plate is positioned to contact only the inner face of the panel at a specific location, allowing the majority of the vertical surface to maintain its original smooth, continuous appearance while still providing secure guardrail attachment.

AI summary
The object of the invention relates to a device for fixing a post (8) on a precast wall arranged in a substantially vertical plane, characterized in that the fixing device comprises, on the one hand, a sleeve (2) configured to receive at least a portion of a post, this sleeve (2) being associated with a positioning mechanism (4) of the sleeve (2) along a substantially vertical axis and on the outer face of a panel (3) of the precast wall and, on the other hand, an anchoring assembly (5) configured to fix the positioning mechanism (4) and the sleeve (2) with a part of the precast wall located within its thickness, the anchoring assembly (5) being arranged to be positioned above a part of the upper edge of a panel (3) of the precast wall.
