Fiber Reinforcement Strip Anchored by U-Bracket for Concrete Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Structural elements such as concrete, masonry, and timber walls are prone to cracking, tilting, and bowing due to inherent weaknesses, particularly under lateral loads and water pressure, necessitating a simple and cost-effective method for anchoring reinforcement materials to prevent deformation and potential collapse.
Innovation Solution
A reinforcement system involving a fiber reinforcement strip adhered to a structural member with U-shaped brackets having legs and a bridge portion, where the strip is wrapped around the bridge and adhered to both the bracket and the member, providing secure anchorage and reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If carbon fiber material is adhered to structural elements to treat deformation, then the structural strength is improved, but the complexity and cost of the system increases
Solution Approach 1:
The reinforcement system is divided into discrete modular components: U-shaped brackets with anchor legs for structural attachment, fiber reinforcement strips for tensile strength, and adhesive material for bonding. This segmentation allows for simplified installation and replacement of individual components without affecting the entire system.
Solution Approach 2:
Adhesive material serves as an intermediary substance that bonds the U-shaped brackets to the structural element and the fiber reinforcement strips to the brackets. This intermediary enables secure attachment while allowing for flexible installation and potential future removal or replacement of components.
2Stability of the object's composition
If traditional anchoring methods are used to reinforce structural elements, then the structural stability is improved, but the ease of installation and cost-effectiveness deteriorates
Solution Approach 1:
The U-shaped brackets are pre-formed with anchor legs designed to be inserted into pre-drilled holes in the structural element. The fiber reinforcement strips are also prepared in advance with adhesive applied, allowing for quick installation by simply wrapping them around the bridge portion and securing them in place.
Solution Approach 2:
The system allows for dynamic adjustment and potential reconfiguration. The adhesive bonds provide sufficient strength for structural reinforcement while permitting future removal or modification of the reinforcement system if needed, offering flexibility not available in permanent mechanical anchoring methods.

AI summary
A reinforcement system includes a structural member such as a concrete wall including a pair of holes formed therein. A fiber reinforcement strip is adhered to the structural member between the pair of holes. A U-shaped bracket includes a pair of legs being adhered in the pair of holes and a bridge portion that overlaps the fiber reinforcement strip, wherein the first end of the fiber reinforcement strip is wrapped around the bridge portion and adhered to an intermediate portion of the fiber reinforcement strip.
