Fiberglass Loop Tie Rod for Concrete Forming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metal tie rods for concrete forming systems are difficult to position, prone to rusting, and can mar the concrete wall when removed, while non-metallic ties lack strength and have poor water sealing capabilities.
Innovation Solution
A loop tie rod made from non-metal fibers like fiberglass, wound around opposed thimble elements, providing strength comparable to metal ties while creating a thermal break and improving water sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal tie rods are used, then strength is improved, but rusting and concrete wall damage occur
Solution Approach 1:
The patent employs a composite tie rod structure consisting of a fiberglass rod surrounded by a metal mesh cage. The fiberglass provides corrosion resistance while the metal cage provides tensile strength. This composite approach allows the tie rod to achieve the necessary strength to hold concrete forms together during pouring while eliminating the rusting problems of solid metal ties and preventing damage to the concrete wall surface upon removal.
2Object-affected harmful factors
If non-metallic ties are used, then rusting and concrete wall damage are reduced, but strength and water sealing capabilities deteriorate
Solution Approach 1:
The patent employs a composite tie rod structure consisting of a fiberglass rod surrounded by a metal mesh cage. The fiberglass provides corrosion resistance while the metal cage provides tensile strength. This composite approach allows the tie rod to achieve the necessary strength to hold concrete forms together during pouring while eliminating the rusting problems of solid metal ties and preventing damage to the concrete wall surface upon removal.
3Strength
If conventional metal tie rods are used, then strength is improved, but positioning difficulty and removal damage increase
Solution Approach 1:
The patent employs a composite tie rod structure consisting of a fiberglass rod surrounded by a metal mesh cage. The fiberglass provides corrosion resistance while the metal cage provides tensile strength. This composite approach allows the tie rod to achieve the necessary strength to hold concrete forms together during pouring while eliminating the rusting problems of solid metal ties and preventing damage to the concrete wall surface upon removal.
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
The fiberglass tie rod offers strength comparable to metal ties, reduces water pathways, and improves bonding with concrete, while being easier to position and remove without damaging the concrete wall.
Implementation Method 1
a continuous fiber wound between the first and second thimble elements to form the tie rod, wherein each of the thimble elements has a main body having a channel formed in an outer surface of the main body, and wherein the fiberglass fiber is disposed within the channel when wound thereabout
Data Source
AI summary
A tie rod suitable for use with known concrete forming systems is constructed from a non-metal fiber, such as fiberglass, that is wound about a pair of opposed thimble elements. The resultant tie rod is as strong as a metal tie rod without the drawbacks of conventional metal tie rods. Each of the thimble elements has a main body having a channel formed in an outer surface of the main body, and the fiberglass fiber is disposed within the channel when wound thereabout.
