Securing Device Hooks for Pre-slab Guardrail Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pre-slabs used in construction often have inadequately secured hollow sections for guardrail posts, leading to instability and potential overturning under significant force, compromising safety and stability.
Innovation Solution
A securing device with multiple hooks and anchoring studs is integrated into the pre-slab, ensuring secure fixation by pinching between frames, preventing unhooking and tipping, and allowing easy installation of construction accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hollow sections are installed in pre-slabs for guardrail posts, then guardrails can be positioned on the pre-slab surface, but the hollow sections are not sufficiently well installed and become illuminated under significant force, causing the guardrail to overturn
Solution Approach 1:
The hollow section is divided into multiple segments: a base portion embedded in the pre-slab, vertical sides, and a top portion forming the guardrail receiver. This segmentation allows each part to be optimized for its specific function - the base for anchoring, the sides for structural integrity, and the top for receiving the guardrail.
Solution Approach 2:
The hollow section is nested within the pre-slab structure, with the base portion embedded in the concrete and the vertical sides extending upward. The guardrail post is then inserted into the hollow section, creating a nested configuration that provides both structural integration and functional accessibility.
2Reliability
If a securing device with multiple hooks is used to fix the accessory to reinforcements, then the accessory is securely pinned between reinforcements preventing detachment, but the device complexity increases
Solution Approach 1:
Multiple hooks are combined into a single integrated securing device that engages with multiple reinforcements simultaneously. The hooks are positioned at different locations and orientations to capture the accessory between the reinforcement bars, creating a multi-point anchoring system from a unified structure.
Solution Approach 2:
The securing device utilizes three-dimensional spatial arrangement of hooks positioned at different heights and angles around the reinforcement bars. This multi-dimensional configuration allows the accessory to be pinned from multiple directions, preventing detachment in any orientation while maintaining structural efficiency.
