Wire Blank Tie for Sandwich Building Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ties for connecting internal and external layers of sandwich building elements are inefficient in production, requiring separate parts and welding, which increases production costs and time.
Innovation Solution
A tie formed from a single wire blank by bending, comprising an internal bar, external bar, bracing, and a loop-like further bond, where the bracing and bars are parallel and angled to form triangles, allowing for direct bending and cutting of the wire to create the entire tie without separate parts or welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ties are produced using separate parts connected by welding, then structural reliability is improved, but production time and cost increase
Solution Approach 1:
The patent merges multiple separate tie components (internal bar, external bar, bracing, and further bond) into a single integrated tie formed from one continuous wire blank. This eliminates the need for welding separate parts together, thereby reducing production time and cost while maintaining structural integrity through the continuous material structure.
2Manufacturing precision
If ties are produced using separate parts connected by welding, then assembly precision is improved, but manufacturing complexity increases
Solution Approach 1:
The patent combines multiple tie components into a single monolithic structure formed from one wire blank through bending and shaping operations. This integration eliminates the complexity of assembling multiple separate parts with precise welding requirements, while the resulting unified structure inherently ensures proper alignment and positioning of all functional elements.
3Reliability
If a looplike further bond is added to the tie, then fastening capability is improved, but wire blank complexity increases
Solution Approach 1:
The patent incorporates the looplike further bond as an integrated feature of the wire blank during the forming process, rather than adding it as a separate component afterward. This preliminary integration of the fastening feature into the base material structure enables enhanced fastening capability while avoiding the complexity of separately manufacturing and attaching additional bonding elements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method significantly speeds up production and reduces costs by eliminating the need for separate parts and welding, while improving fastening capabilities through a unified wire blank structure.
Implementation Method 1
the whole tie, i.e. bracing, internal bar and external bar and further bond are preferably formed from the one and the same wire blank by bending

AI summary
A tie 1 for connecting internal layer 12 and external layer 13 of a sandwich building element 11 to each other, which tie 1 comprises an internal bar 2 fittable into the internal layer 12 of the building element and an external bar 3 which is fittable into the external layer of the building element, and a bracing 4 connecting the internal bar 2 and external bar 3. The tie 1 comprises a further bond 15 for fastening the tie 1 to the building element 11, and at least a part of the bracing 4, at least a part of the inner bar and outer bar 2, 3 and the further bond 15 are formed form the same wire blank by bending, and which further bond 15 is formed in wire blank between the bracing 4 and the said bar 2, 3. A sandwich building element 11 comprises an internal layer 12 and an external layer 13, which are bound to each other with a tie 1, the internal bar 2 of which tie 1 is placed into concrete of the internal layer 12 and the external bar 3 into concrete of the external layer 13 and further bond 15 into concrete of internal layer 12 or external layer 13.
