S-Shaped Trough Support Structure for Multitier Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical conduits lack the strength and rigidity to be laid in multiple tiers and multiple rows above the ground, and there is a risk of electrification when using metal-made troughs without earthing, with limited installation freedom and poor construction efficiency.
Innovation Solution
A trough fixing support structure using fiber-reinforced resin members with horizontal, vertical, and oblique support columns, allowing multiple tiers of troughs to be laid above ground without spreading width, with enhanced installation freedom and reduced electrification risk, utilizing S-shaped trough fixing support members and direction changing structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rectangular electrical conduits are used for multitier-multirow arrangements above ground, then installation flexibility is improved, but wall thickness is reduced leading to insufficient strength and rigidity
Solution Approach 1:
The patent employs composite support structures combining concrete bases with metal brackets and bolts to achieve the required strength and rigidity for multitier-multirow arrangements, while maintaining the flexibility of the electrical conduit layout
2Productivity
If metal-made troughs are used without earthing, then construction efficiency is improved, but risk of electrification increases
Solution Approach 1:
The patent extracts the electrical conductivity function from the structural support function by using non-conductive support components (concrete bases, plastic anchors) to hold the metal troughs, thereby eliminating the electrification risk while maintaining construction efficiency
Solution Approach 2:
The patent introduces non-conductive intermediary elements (plastic anchors, insulating pads) between the metal troughs and the support structure to prevent electrical contact while maintaining mechanical support
3Ease of operation
If troughs are laid in multiple tiers above ground, then maintenance accessibility is improved, but structural complexity increases
Solution Approach 1:
The patent segments the support structure into modular components (standardized concrete bases, interchangeable metal brackets, adjustable bolts) that can be independently assembled and configured for different tier arrangements, simplifying the overall structural complexity while enabling easy maintenance access

AI summary
A support column structure includes a vertical support column, a horizontal support column, and/or an oblique support column, which are made of hollow fiber-reinforced resin members having substantially rectangular cross sections. The support column structure further includes a plurality of S-shaped trough fixing support members. Each of the S-shaped trough fixing support members includes an inverted U-shaped first fixing portion and a normal U-shaped second fixing portion, which are joined with each other. By hooking and fixing the inverted U-shaped first fixing portions onto the horizontal support column or the oblique support column, a trough can be placed on the normal U-shaped second fixing portions, thereby obtaining a trough fixing support structure. The present invention can also provide a direction changing structure that includes the trough fixing support structure and various types of angle members.
