Floating Floor Holder With Protective Cover For Wire Fabric
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for creating floating slabs with integrated holders face challenges such as limited rigidity, hazardous working conditions, and inefficiencies in positioning and bonding of welded wire fabric due to protruding rods, leading to potential displacement and fracture during the concrete setting process.
Innovation Solution
A holder design featuring horizontal tubes at various levels to support and connect welded wire fabric layers, with rods inserted into these tubes to secure and align the mesh structures, preventing displacement and ensuring proper bonding, and a lid and base for concrete insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If rods are welded to the holder structure to facilitate bundling of welded wire fabric, then the positioning and bonding of wire fabric is improved, but the working conditions become hazardous and labor intensity increases
Solution Approach 1:
The patent extracts the hazardous protruding rod ends from the work zone by providing a protective cover that encloses the holder structure. This removes the sharp points and welding locations from the operator's environment, eliminating the safety hazards while preserving the rod bundling function for wire fabric positioning.
Solution Approach 2:
The protective cover is divided into multiple segments or panels that can be assembled around the holder structure. This segmentation allows the cover to accommodate different holder configurations and rod arrangements while providing comprehensive protection, reducing labor intensity in installation and maintenance.
2Ease of manufacture
If rods are arranged to overlie the grid for facilitating bundling, then wire fabric positioning is improved, but the structure becomes less rigid and holders may move during concrete pouring
Solution Approach 1:
The protective cover is installed on the holder structure before the concrete pouring operation. This preliminary action secures the holder in its predetermined position and protects it from displacement during the concrete pouring and setting process, preventing the formation of weak zones that could lead to slab fracture.
Solution Approach 2:
The protective cover provides localized reinforcement and stabilization to the holder structure at critical positions. By covering specific areas where holders are most vulnerable to displacement, the system maintains overall structural rigidity while still allowing the rod bundling configuration to facilitate wire fabric positioning.
3Measurement precision
If the holder structure is exposed during concrete pouring, then positioning accuracy can be monitored, but displacement and fracture risks increase due to operator movements and concrete pressure
Solution Approach 1:
The protective cover is positioned on the holder structure before concrete pouring begins. This allows for preliminary verification of holder positioning accuracy through transparent or accessible portions of the cover, and then protects the holder from displacement during the concrete pouring and setting process, ensuring structural integrity.
Solution Approach 2:
The protective cover acts as an intermediary barrier between the holder structure and the concrete mixture. It prevents direct contact between the concrete and the holder, eliminating the harmful effect of concrete pressure and operator movements on holder position stability, while still allowing for monitoring of positioning accuracy through the cover material.
