Self-Furring Welded Wire Mesh with Staggered V-Shaped Furrs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing welded wire mesh for concrete and stucco structures requires separate furring elements for proper positioning, increasing material and labor costs, and the process of bending wires to form U-shaped troughs weakens the mesh's structural integrity.
Innovation Solution
A self-furring welded wire mesh with V-shaped spacing furrs formed in selected longitudinal wires, where the furrs are staggered and misaligned to avoid adjacent placement, and additional wire is fed into the furrs to maintain wire strength, using a forming station with adjustable pusher assemblies and welding heads to create the mesh without deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate furring elements are added to position the mesh in concrete panels, then the mesh positioning accuracy is improved, but the material cost and construction labor increase
Solution Approach 1:
The patent combines the mesh structure with integrated furring elements formed directly from the wire material itself. The transverse wires are bent to create U-shaped troughs that serve as both structural components and positioning elements, eliminating the need for separate furring elements and reducing construction complexity while maintaining positioning accuracy
Solution Approach 2:
The mesh structure provides its own positioning function through the integrated furring elements. The U-shaped troughs formed by bending transverse wires create self-supporting feet that automatically position the mesh at the correct elevation in concrete panels without requiring external furring elements or additional construction steps
2Device complexity
If transverse wires are bent to form U-shaped spacing furrs, then separate furring elements are eliminated, but the wire structural integrity is weakened
Solution Approach 1:
The patent applies different properties to different parts of the wire structure. The transverse wires are bent into U-shaped troughs at specific locations to provide positioning function, while the longitudinal wires remain straight and undeformed to maintain structural integrity. This localized deformation approach ensures that only the necessary portions of the wire are modified, preserving the overall strength of the mesh
Solution Approach 2:
The patent creates a composite structure where the bent transverse wires forming U-shaped troughs work together with the straight longitudinal wires. The combination of deformed and undeformed wire portions creates a system where the undeformed longitudinal wires provide structural strength while the deformed transverse wires provide positioning function, effectively combining multiple functions within the same mesh structure

AI summary
A self-furring welded wire mesh for reinforcing generally planar concrete and stucco structures is formed of a matrix of longitudinally and transversely extending wires disposed about a first common plane and welded together at their intersections. A selected plurality of the longitudinally extending wires each define a plurality of generally V-shaped spacing furrs therein extending generally perpendicular to the first plane with the bottoms of the furrs being disposed in a second plane spaced from the first plane a distance substantially equal to one-half of the predetermined thickness of the concrete panel. The spacing furrs in the selected longitudinally extending wires are located so as to be longitudinally and transversely staggered along the mesh. The spacing furrs are formed by pushing portions of the selected longitudinal wire perpendicular to the axis of the wires while holding an upstream portion thereof in a fixed disposition so as to form these without damaging or thinning the wires along the spacing furrs.
