Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stirrup structures in reinforced concrete construction are inconvenient to modify and time-consuming, making it difficult to add additional main bars and prolonging the construction process.
Innovation Solution
A rebar cage module comprising a first and second opening rebar net, where the first net partially covers the second net, forming overlapping accommodating portions, allowing for easier assembly and integration of main bars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If stirrups are disposed on the surface across the main bars to distribute hooping force evenly, then the structural performance is improved, but it becomes inconvenient to add more main bars and the construction time increases
Solution Approach 1:
The rebar cage is divided into modular units with standardized opening rebar nets. Each module can be independently assembled and then combined, allowing flexible addition of main bars by simply connecting additional modules without disrupting the existing stirrup arrangement.
Solution Approach 2:
The opening rebar nets are pre-assembled with stirrups before main bars are installed. This preliminary preparation of the cage structure with predetermined openings allows main bars to be added efficiently without requiring post-assembly modifications to the stirrup configuration.
2Reliability
If stirrups are disposed on the surface across the main bars to form reinforcement structure, then the reinforcement function is achieved, but the manufacturing time is prolonged
Solution Approach 1:
Multiple rebar components including opening rebar nets, stirrups, and main bars are merged into integrated modular assemblies. This consolidation allows parallel assembly operations and reduces the sequential steps required, thereby decreasing manufacturing time while maintaining reinforcement integrity.
Solution Approach 2:
The opening rebar nets and stirrups are pre-assembled into complete cage modules before main bars are installed. This preliminary preparation enables faster on-site assembly and reduces the overall manufacturing timeline while ensuring the reinforcement structure meets structural requirements.
3Stability of the object's composition
If traditional rebar cage assembly method is used, then the structural integrity is ensured, but the construction process is time-consuming
Solution Approach 1:
The rebar cage is segmented into standardized modules with opening rebar nets that can be pre-fabricated and quality-checked separately. This segmentation maintains structural integrity through standardized connection details while enabling parallel fabrication processes that reduce overall construction time.
Solution Approach 2:
Complete rebar cage modules are pre-assembled and quality-inspected before delivery to the construction site. This preliminary action ensures structural integrity is verified during manufacturing rather than during installation, preventing rework and reducing on-site construction time.

AI summary
The present invention provides a rebar cage module comprising a first opening rebar net and a second opening rebar net. The first opening rebar net extends from a central direction, and partially forms an elongated groove shape enclosing a first accommodating portion, and has a first opening. The second opening rebar net extends from the central direction, and partially surrounds the central direction to form an elongated groove shape, and has a second opening oriented to the opposite direction with the first opening. Wherein, the first opening rebar net at least partially covers the second opening rebar net, the first opening rebar net is at least partially distributed in the second opening, and the first opening rebar net extends at least partially through the second opening into the second accommodating portion, and making the first accommodating portion and the second accommodating portion at least partially overlap.
