Reinforced Pedestal Grid Structure for High Load False Floors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pedestals for supporting surfaces or false floors lack sufficient weight-bearing capacity and have limited height, resulting in small gaps between the fixed surface and the false surface, which restricts the installation of larger diameter pipes and only allows for the laying of cables or thin tubes.
Innovation Solution
A reinforced pedestal with a truncated conical tubular body and external ribs, combined with a grid structure composed of reinforced pedestals and guide crossheads, to support raised surfaces and accommodate service installations like pipes and cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional pedestals are used to support false floors, then the structure is simple and easy to install, but the weight-bearing capacity is insufficient and the height is limited
Solution Approach 1:
The pedestal is divided into multiple segments: a base portion, a column portion with external ribs, and an upper surface portion. This segmentation allows each part to contribute to the overall strength while maintaining manufacturability and ease of assembly
Solution Approach 2:
The pedestal utilizes composite structural design combining the base portion, reinforced column portion with external ribs, and upper surface portion. This composite structure significantly enhances weight-bearing capacity compared to conventional single-piece pedestals
2Length of stationary object
If conventional pedestals with limited height are used, then the pedestal structure remains simple, but the gap between fixed surface and false surface is too small to accommodate larger diameter pipes
Solution Approach 1:
By segmenting the pedestal into base, column, and upper surface portions, the design achieves greater overall height while maintaining structural integrity. The column portion can be extended vertically to provide adequate clearance for pipe installations
Solution Approach 2:
External ribs are added to the column portion, transitioning from a simple cylindrical form to a dimensionally enhanced structure. This increases height and structural capacity without proportionally increasing material usage
3Length of stationary object
If the pedestal height is increased to accommodate larger pipes, then pipe installation space is sufficient, but the weight-bearing capacity may be compromised
Solution Approach 1:
The composite structure combining base portion, reinforced column with external ribs, and upper surface portion provides both increased height and enhanced strength. The external ribs act as structural reinforcement that maintains load-bearing capacity despite increased height
Solution Approach 2:
The external ribs on the column portion provide structural reinforcement similar to corrugation, enhancing the moment of inertia and bending resistance of the column, thereby maintaining strength while allowing greater height
