Metal Wire Arch Fixing Device for Concrete Floor Posts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing safety barriers on concrete floors require on-site tool usage, which can be inconvenient and inefficient.
Innovation Solution
A device comprising a metal wire arch with hooked legs and a flexible branch that can be elastically braced between reinforcing wires, allowing for tool-free installation by hooking onto pre-existing wires during concrete prefabrication or pouring, with a looped end to secure the branch between wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fixing devices with bases and fixing members are used, then secure anchoring to concrete floor is achieved, but on-site tool usage and complex installation process are required
Solution Approach 1:
The fixing device is segmented into three functional parts: an arch component for engagement with reinforcing wires, a branch component for elastic bracing between wires, and a loop component for securing the branch. This segmentation allows each part to perform its specific function independently, simplifying the overall installation process while maintaining secure anchoring capability
Solution Approach 2:
The arch and branch components are pre-configured with specific geometries (arch shape, perpendicular branch extension, loop at branch end) that enable automatic engagement with the reinforcing wires during concrete prefabrication or pouring, eliminating the need for on-site tool usage and complex assembly operations
2Reliability
If safety barriers are installed on concrete floors with edges, then worker safety is improved, but installation requires tools and time-consuming procedures
Solution Approach 1:
The device is designed to self-anchor to the reinforcing wires through the arch hooking onto one wire and the branch elastically bracing between two wires with the loop securing the branch. This self-service mechanism eliminates the need for external tools or complex installation procedures, significantly improving installation efficiency while maintaining reliable safety barrier functionality
Solution Approach 2:
The device utilizes elastic deformation of the branch component as a key parameter change mechanism. The branch is extended perpendicular to the arch plane with a length greater than the wire spacing, allowing it to elastically brace between reinforcing wires. This parameter change enables automatic securing without tools, improving both productivity and reliability

Function Achieved in This Case
Enables efficient and tool-free installation of safety barriers on concrete floors, ensuring secure anchoring and simplifying the process both during prefabrication and on-site concrete pouring.
Implementation Method 1
one of the legs being extended after its conformation into a branch extending substantially perpendicular to the plane of the arch and whose length is greater than the distance separating the two reinforcement son so that this branch can be elastically braced between these son

AI summary
The device has a metallic wire folded into an arch in a plane, where the arch comprises jambs (2a, 2b) folded for being hooked underneath a reinforcing wire (10). The jamb (2b) is extended after its folding into a branch (5) that extends perpendicular to the plane. The branch has a length that is greater than a distance (D) separating reinforcing wires (10, 11) such that the branch is elastically pressed between the wires (10, 11). An independent claim is also included for a method of fabricating a concrete floor.
