Foundation Pile With Double-Layered Web and Single-Layered Flanges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foundation piles constructed using metal rolling techniques are limited in flange configurations, often resulting in double-layered flanges that are expensive and inefficient, and are susceptible to bending or bending moments under lateral or overturning loads, making them difficult to reinforce without increasing cost and weight.
Innovation Solution
A foundation pile design featuring a double-layered web with single-layered flanges, where the flanges extend from the web segments in various orientations and configurations, including non-perpendicular angles, and may incorporate flange stiffeners, mechanical fasteners, or chemical bonding agents for enhanced strength and stability, formed from a single sheet of material without the need for additional coupling agents.

Engineering Contradiction Analysis
1Productivity
If conventional metal rolling techniques are used to construct foundation piles, then production efficiency is improved, but flange configuration flexibility deteriorates and double-layered flanges result in increased cost and weight
Solution Approach 1:
The foundation pile is divided into multiple segments including a first pile segment and a second pile segment that can be coupled together. Each segment can have optimized flange configurations (single-layered or double-layered) depending on the specific structural requirements, allowing flexibility in design while maintaining production efficiency through standardized segment fabrication
Solution Approach 2:
Different portions of the foundation pile can have different flange configurations - single-layered flanges in some segments and double-layered flanges in others - based on the local structural demands. This allows optimization of material usage and cost while maintaining the necessary adaptability for various application scenarios
2Strength
If foundation piles are reinforced to withstand bending moments under lateral loads, then structural strength is improved, but cost and weight increase
Solution Approach 1:
The foundation pile incorporates asymmetric flange configurations where front flanges and rear flanges can have different dimensions, orientations, or layer configurations. This asymmetry allows optimized resistance to bending moments in specific directions while minimizing unnecessary material and weight
Solution Approach 2:
The pile segments can be configured with varying flange orientations and dimensions along the length of the pile, allowing the structural properties to dynamically adapt to different loading conditions at different locations, thereby providing enhanced bending resistance where needed without uniformly increasing weight throughout the entire structure
