Segmented Steel Support Beam for Slab Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of supporting beams for slab systems is complex and costly due to their composite design, which often involves continuous steel sections filled with concrete, requiring intricate construction and high material usage.
Innovation Solution
A supporting beam with a divided steel support, comprising multiple pieces that extend in the longitudinal direction, allowing for a pre-fabricated composite design with a gap between the support parts, enabling easier assembly and material efficiency, and can be used for various widths and heights by adjusting the spacing between the parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a continuous steel support is used in composite design, then load-bearing capacity is improved, but production complexity and cost increase
Solution Approach 1:
The steel support is divided into multiple discrete segments instead of using a continuous support. These segments are positioned at regular intervals along the longitudinal direction and connected through concrete, creating a modular structure that reduces production complexity while maintaining load-bearing capacity through the composite action of steel segments and concrete
2Stability of the object's composition
If a continuous steel support is used, then structural stability is improved, but material usage and cost increase
Solution Approach 1:
The support structure is segmented into discrete steel segments rather than using a continuous steel support. This segmentation reduces the total quantity of steel material required while the concrete connections between segments provide the necessary structural stability and continuity for load transfer
Solution Approach 2:
The invention uses a composite design combining steel segments with concrete. The concrete serves both as connection material between steel segments and as structural element, creating a composite support system that optimizes material usage by leveraging the complementary properties of steel (tensile strength) and concrete (compressive strength and continuity)
