Toothed Groove Building Element for Rapid Structural Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction of larger buildings, such as parking houses, is time-consuming and costly due to the difficulty in welding steel elements in restricted spaces, followed by the labor-intensive installation of reinforcement and casting of layers over load bearing and floor elements.
Innovation Solution
A double T-shaped building element with a toothed groove design and rapid coupling devices allows for efficient connection of building elements to load bearing elements, eliminating the need for welding and enabling telescoping elements to be cast into load bearing elements, along with the use of reinforcement iron and threaded struts for enhanced structural integrity and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to connect steel elements in restricted spaces, then structural connection is achieved, but construction time and complexity increase significantly
Solution Approach 1:
The reinforcement iron is pre-installed on the building elements before assembly, and the sleeves are pre-cast into the building elements. This preliminary preparation eliminates the need for on-site welding and complex reinforcement installation, significantly reducing construction time while maintaining structural strength.
Solution Approach 2:
The invention introduces sleeves as intermediary elements that are cast into the building elements and receive telescoping elements. This intermediary mechanism provides a simplified connection system that replaces welding, allowing for rapid assembly while ensuring structural integrity through the reinforcement iron that extends into the load bearing elements.
2Strength
If reinforcement is installed across the complete surface and casting is performed over load bearing elements, then structural integrity is ensured, but construction complexity and cost increase
Solution Approach 1:
Instead of installing reinforcement across the complete surface, the invention places reinforcement iron locally at critical connection points - specifically on the building elements where it will be cast into the load bearing elements. This localized reinforcement approach maintains structural integrity while significantly reducing construction complexity and material usage.
Solution Approach 2:
The reinforcement iron is pre-positioned on the building elements before assembly, and the sleeves are pre-cast into the building elements. This preliminary action eliminates the need for complex on-site reinforcement installation and casting operations, simplifying the construction process while ensuring structural integrity.
3Productivity
If telescoping elements are cast into load bearing elements, then rapid connection is enabled, but precision casting is required
Solution Approach 1:
The sleeves are pre-cast into the building elements with the telescoping elements already in place during the building element manufacturing process. This preliminary action transfers the precision casting requirement to the controlled factory environment rather than requiring precise field casting, enabling rapid on-site assembly while maintaining high precision through controlled manufacturing conditions.
