Composite Floor Structure with Protruding Bar Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor structures with crossed reinforcement rods face difficulties in manufacturing due to the need for full shoring, which increases labor, cost, and complexity, while also being unable to correctly house or support reticular reinforcement metal structures.
Innovation Solution
A floor structure comprising composite construction elements with an elongated body of expanded plastic material and a substantially reticular reinforcement metal structure, where the reinforcement metal structure is supported by a protruding reinforcing section bar at a predetermined distance from the upper face of the expanded plastic material, allowing for self-supporting characteristics and reduced use of temporary supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If full shoring is used to contain concrete casting, then manufacturing capability is improved, but labor and cost increase
Solution Approach 1:
The composite construction element is designed to be self-supporting during concrete casting, eliminating the need for external full shoring. The element's structural design allows it to withstand the weight and pressure of the concrete without requiring additional temporary supporting formwork, thereby reducing labor and complexity while maintaining manufacturing capability.
Solution Approach 2:
The composite construction element serves multiple functions simultaneously: it acts as both the structural floor element and the supporting formwork during concrete casting. This multi-functionality eliminates the need for separate full shoring systems, reducing device complexity and labor requirements while maintaining ease of manufacture.
2Weight of stationary object
If composite construction elements are used, then weight is reduced, but ability to support reticular reinforcement metal structure deteriorates
Solution Approach 1:
The construction element combines expanded plastic material with integrated reinforcing section bars to create a composite structure. This composite design provides both the weight reduction benefits of expanded plastic and the strength necessary to support reticular reinforcement metal structures, resolving the contradiction between lightness and support capability.
Solution Approach 2:
The reinforcing section bars are strategically positioned within the composite construction element at locations where maximum support strength is needed. This local reinforcement approach ensures adequate support capability for the reticular reinforcement metal structure while maintaining overall element lightness and avoiding unnecessary weight throughout the entire structure.
3Strength
If protruding bar upper portion is added, then support capability is improved, but element complexity increases
Solution Approach 1:
The reinforcing section bar with its protruding upper portion is integrated directly into the composite construction element during manufacturing. This merging of the support structure with the floor element itself provides enhanced support capability while avoiding the need for separate, complex assembly operations, thereby limiting the increase in overall element complexity.
