Nested Concrete Reinforcement Mesh for Lateral Load Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete strengthening structures are inadequate in effectively absorbing both lateral and longitudinal forces, particularly under extreme conditions like storms, earthquakes, or tsunamis, and lack the complexity and ease of handling in manufacturing.
Innovation Solution
A structure comprising a bended mesh inserted into an outer cage, both formed from pre-formed meshes with lateral and assembly bars, where the bended mesh is enclosed by the outer cage's lateral bars, enhancing reinforcement capabilities by absorbing forces from both directions and allowing for complex final structures with improved manageability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single pre-formed mesh is bent and used for strengthening concrete, then the structure can be manufactured with relatively simple processes, but the reinforcement capability under lateral loads is insufficient
Solution Approach 1:
The patent applies nesting by placing one pre-formed mesh inside another pre-formed mesh, creating a multi-layered reinforcement structure. The inner mesh is positioned within the outer mesh, and both are embedded in concrete together. This nested configuration allows the structure to achieve superior reinforcement capability under lateral loads while maintaining manufacturing simplicity, as each mesh can be prepared independently before assembly.
Solution Approach 2:
The patent creates a composite reinforcement structure by combining multiple pre-formed meshes with different orientations and configurations. The outer mesh and inner mesh work together as a composite system, where each mesh contributes to the overall reinforcement capability. This composite approach enables the structure to resist lateral loads more effectively than a single mesh could achieve alone.
2Reliability
If multiple pre-formed meshes are combined to improve reinforcement properties, then the structure can absorb both lateral and longitudinal forces effectively, but the handling and assembly difficulty increases
Solution Approach 1:
The patent applies preliminary action by pre-forming the meshes into their final three-dimensional configurations before assembly. The pre-formed meshes are manufactured with the desired shapes and dimensions, including any necessary bends and contours, so that they can be directly assembled into the nested structure without requiring complex on-site forming operations. This preliminary preparation significantly eases handling and assembly while ensuring reliable reinforcement performance.
3Strength
If complex final structures are achieved through multiple bended meshes, then the reinforcement properties are enhanced, but the manufacturing cost increases
Solution Approach 1:
The patent applies segmentation by dividing the reinforcement structure into multiple separate pre-formed mesh components that can be manufactured independently using standardized processes. Each mesh can be produced in a factory setting using efficient bending and forming operations, then assembled on-site by simply nesting one mesh inside another. This segmentation allows for economies of scale in manufacturing while achieving complex final structures with enhanced reinforcement properties.

AI summary
A structure for strengthening concrete comprises at least one bended mesh formed of a pre-formed mesh consisting of lateral bars arranged in parallel and assembly bars arranged in parallel, the assembly bars being arranged perpendicular to the lateral bars and connecting the lateral bars, and an outer cage formed of a pre-formed mesh consisting of lateral bars arranged in parallel and assembly bars arranged in parallel, the assembly bars being arranged perpendicular to the lateral bars and connecting the lateral bars. The at least one bended mesh is placed inside the outer cage such that all assembly bars of the at least one bended mesh are enclosed by lateral bars of the outer cage.
