Innovation Solution
A reinforcement cage design featuring a plurality of reinforcement units with interconnected stirrups and main bars, along with a jig system that includes movable positioning and holding elements, allows for precise adjustment and assembly of the stirrups to form a robust and efficient reinforcement cage structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional manual assembly methods are used for reinforcement cages with numerous interwoven stirrups, then the structure can be assembled, but the construction process requires skilled workers and becomes complex and time-consuming
Solution Approach 1:
The reinforcement cage is divided into multiple modular units, each containing a standardized configuration of stirrups and main bars. These modular units can be independently assembled and then connected to form the complete reinforcement cage structure, significantly simplifying the manufacturing process
Solution Approach 2:
A positioning device is introduced as an intermediary tool to facilitate the assembly of stirrups and main bars. The positioning device includes positioning members that guide and align the reinforcement elements during assembly, making the process easier and more systematic without requiring highly skilled workers
2Productivity
If traditional manual assembly methods are used for reinforcement cages, then the structure can be assembled, but the process requires skilled workers and reduces efficiency
Solution Approach 1:
The positioning device is designed to guide the assembly process automatically through its positioning members, which self-align the stirrups and main bars during assembly. This self-guiding mechanism eliminates the need for skilled workers to manually position and align elements, thereby improving productivity while reducing skill requirements
Solution Approach 2:
The positioning members are pre-configured in the positioning device to establish the correct positions and orientations of stirrups and main bars before assembly begins. This preliminary setup ensures that workers only need to follow the pre-established guides, significantly improving assembly efficiency and reducing the need for skilled judgment during the process

AI summary
The subject disclosure relates to a reinforcement cage, a jig and a method for making the reinforcement cage. The reinforcement cage includes a plurality of reinforcement units, which are arranged along a first direction, and a plurality of main bars. Each reinforcement unit includes a first stirrup, which is substantially rectangular, at least one second stirrup and at least one third stirrup. The first stirrup includes a first side, a second side, a third side and a fourth side. The first side and the third side are opposite to each other, and the second side and the fourth side are opposite to each other. The at least one second stirrup is connected to the first side and the third side of the first stirrup. The at least one third stirrup is connected to the second side and the fourth side of the first stirrup and substantially perpendicular to and fixed to the at least one second stirrup. The plurality of main bars extend along the first direction and through the reinforcement units, are adjacent to the first side, the second side, the third side and the fourth side of the first stirrup and are fixed to the reinforcement units.
