Arc Bracket Connection for Steel Pipe Struts Without H-Beams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strut connection structures for retaining walls in underground excavation require separate manufacturing of connectors, are costly, and reduce axial supporting force when H-beams are interposed, leading to increased strut numbers and deformation issues.
Innovation Solution
A strut connection bracket and device using circular steel pipe struts with arc-shaped bodies and flanges, coupled by first and second coupling members, which connect steel pipe struts and inclined struts, enhancing axial support and preventing slippage through contact support protrusions and slip prevention parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If H-beam is interposed between steel pipe strut and wale, then connection is enabled, but axial supporting force is reduced
Solution Approach 1:
The invention extracts and removes the H-beam component from the connection structure, using only circular steel pipe struts to connect to the wale. This eliminates the weakness introduced by the H-beam while maintaining connection capability through the arc-shaped bracket design that directly engages with the wale.
Solution Approach 2:
The invention uses a composite connection structure combining the arc-shaped bracket with coupling members to create a unified connection system that maintains the high axial supporting force of circular steel pipe struts while enabling secure connection to the wale.
2Ease of operation
If connector is separately manufactured for strut connection, then connection structure is formed, but manufacturing cost and complexity increase
Solution Approach 1:
The invention merges the bracket and coupling members into a single integrated strut connection bracket that can be manufactured as one piece. This eliminates the need for separate connector manufacturing and assembly, reducing both cost and complexity while maintaining connection functionality.
Solution Approach 2:
The strut connection bracket is designed as a universal component that can connect steel pipe struts to wales in various configurations. The arc-shaped body and coupling members provide multi-functional capability for different connection scenarios, eliminating the need for multiple specialized connectors.
3Device complexity
If strut supporting force is concentrated on narrow wale portion, then direct connection is achieved, but wale deformation occurs
Solution Approach 1:
The invention uses an arc-shaped bracket body that conforms to the curvature of the circular steel pipe strut. This curved design distributes the supporting force along the arc contact surface rather than concentrating it at a single point, preventing wale deformation while maintaining connection simplicity.
