Solution Overview
Problem
Existing construction methods lack efficient use of thin gauge vertical metallic elements for both interior and exterior framing, particularly in rapid on-site assembly techniques, where there is a need for versatile metallic structural elements that can function as both load-bearing and exterior surfaces.
Innovation Solution
A construction system utilizing a three-walled elongate member with securement brackets that transfer shear force into concrete, allowing for vertical or horizontal use in walls, floors, and roofs, with components that can be cut to desired lengths and complementarily engaged to secure to structural supports, featuring a hollow web and securement brackets in various geometric shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If thin gauge vertical metallic elements are used for rapid on-site assembly, then assembly speed and productivity are improved, but structural strength and load-bearing capacity deteriorate
Solution Approach 1:
The patent combines thin gauge metallic elements with concrete to create a composite structural system. The metal formwork provides rapid assembly capability while the concrete infill provides structural strength, resolving the contradiction between assembly speed and structural integrity.
Solution Approach 2:
The structure is divided into modular components: thin gauge metal formwork sections that can be rapidly assembled, and concrete infill sections that provide structural strength. This segmentation allows each component to optimize its specific function.
2Adaptability or versatility
If thin gauge metallic elements are used for both interior and exterior framing, then material versatility and adaptability are improved, but structural reliability deteriorates
Solution Approach 1:
The thin gauge metallic elements are designed to serve multiple functions: acting as formwork during construction, providing exterior framing, and serving as interior framing members. This multi-functionality improves versatility while the concrete infill ensures structural reliability.
Solution Approach 2:
Concrete acts as an intermediary material that enhances the structural reliability of thin gauge metallic elements. The concrete infill works together with the metal formwork to create a reliable composite structure that maintains both versatility and structural integrity.
3Strength
If traditional steel bars are used for bearing structures, then structural strength is improved, but weight and material complexity increase
Solution Approach 1:
The patent replaces traditional heavy steel bars with a composite system using thin gauge metal formwork and concrete infill. This composite approach achieves comparable bearing capacity while significantly reducing the weight of metallic components required.
Solution Approach 2:
The invention changes the parameters of the structural system by transitioning from solid steel bars to thin gauge metal formwork combined with concrete infill. This parameter change reduces metal weight while maintaining or improving structural strength through the composite action.
