Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for creating connection reinforcement between a floor slab and a wall made of reinforced concrete are time-consuming.
Innovation Solution
A connection cage composed of parallel longitudinal wires and transverse wires, forming hairpin-shaped brackets with end hooks for anchoring, which can be easily bent and assembled to reduce installation time and enhance reinforcement strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If connection cages are made from U-shaped brackets connected by transverse wires and assembled in situ, then the reinforcement structure can be created, but the installation time is excessive
Solution Approach 1:
The connection cage is pre-assembled in a factory setting before delivery to the construction site. The longitudinal wires are pre-positioned and the transverse wires are pre-installed, transforming a complex on-site assembly process into a simple placement operation. This preliminary assembly dramatically reduces installation time while maintaining structural integrity.
Solution Approach 2:
Multiple reinforcement elements (longitudinal wires, transverse wires, and anchoring components) are merged into a single integrated connection cage unit. This consolidation allows the entire reinforcement structure to be manufactured once and installed as one component, eliminating the need for time-consuming on-site assembly of separate elements.
2Strength
If multiple transverse wires are used to connect U-shaped brackets, then the connection strength is sufficient, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The connection cage is segmented into distinct functional components: longitudinal wires for primary reinforcement, transverse wires for lateral connection, and end hooks for anchoring. Each segment is optimized for its specific function and can be manufactured independently, then assembled into the complete structure before delivery, reducing on-site assembly complexity.
Solution Approach 2:
The transverse wires are designed to automatically position and secure the longitudinal wires through their inherent geometry and connection mechanisms. The structure is self-assembling to a large extent, requiring minimal manual intervention during installation, thus reducing assembly complexity while maintaining connection strength.

AI summary
The cage has longitudinal wires (10) made from concrete reinforcement steel and connecting a hairpin-shaped bracket with side pieces (16, 17), where the wires are arranged parallel. Transverse wires intersect orthogonal to the longitudinal wires, and a bottom rod stands right-angle to the bracket. A connecting plane parallel to a plane comprising the bottom rod limits a bottom section (8) of the cage, where the bottom section is arranged in an area of a bottom plate. A wall section (9) for arrangement in a wall area (2) is provided against middle sections of the bracket.
