Guide Bracket for Direct Tensile Force Application to H-Beam Piles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional earth-retaining methods face difficulties in effectively applying tensile force to piles, often requiring complex structures and high construction costs to prevent pile collapse due to earth pressure.
Innovation Solution
A temporary earth-retaining structure using a guide bracket that includes a pile with H-beam shape, a ground anchor, and a guide bracket to distribute tensile force evenly across the pile's flange, preventing separation of the tensile member and maintaining a consistent distance between its components to stabilize the pile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional earth-retaining methods are used to apply tensile force to the pile, then the pile can be prevented from collapsing, but the structure becomes complex and construction cost increases
Solution Approach 1:
The guide bracket acts as an intermediary device that redirects the tensile force from the ground anchor to the pile flange. It includes a guide hole that guides the tensile member and a contact surface that distributes the force to the flange, simplifying the force transmission path while maintaining reliability
Solution Approach 2:
The guide bracket is divided into functional segments: a base plate for mounting, a guide hole for tensile member routing, and a contact surface for force distribution. This segmentation allows each component to perform its specific function efficiently, reducing overall structural complexity
2Reliability
If tensile force is applied to the pile without proper distribution, then the pile may collapse, but distributing the force requires complex structures
Solution Approach 1:
The contact surface of the guide bracket is designed with specific local properties - a curved or flat surface that contacts the tensile member at a precise location. This local quality ensures uniform force distribution across the flange width without requiring complex distribution mechanisms
Solution Approach 2:
The guide bracket changes the directional parameter of the tensile force from a vertical orientation to a horizontal orientation along the flange. By altering the force vector direction through the guide hole and contact surface geometry, the system achieves effective force distribution without additional complex structures
3Reliability
If the tensile member is not properly guided, then it may separate outward from the guide bracket, but preventing separation requires additional constraints
Solution Approach 1:
The guide bracket is pre-installed on the pile flange before the tensile member is fully tensioned. The guide hole is positioned and oriented in advance to receive the tensile member, ensuring proper alignment and preventing outward separation without requiring additional constraint mechanisms during operation

AI summary
A temporary earth-retaining structure uses a guide bracket. Tensile force can be directly applied to a pile by using a guide bracket having a simple structure. Mudslide and collapse caused by the earth pressure of backfill soil can be more effectively prevented by means of the tensile force directly applied to the pile. In addition, the guide bracket according to embodiments of the present invention has a simpler structure and is more easily constructed than a conventional bracket, and thus can be constructed at very low cost.
