Reinforced Scaffold Running Board for Long-Span Bending Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scaffolds with long step board portions are prone to bending under the weight of workers due to lack of adequate support, particularly when intermediate sections are unsupported.
Innovation Solution
Incorporating a reinforcement member with vertically spaced extensions and coupling portions at the ends of the step board portion, supported by multiple support members and an auxiliary support member, which are integrally formed and joined for enhanced strength and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the step board portion is made long to increase working area, then the usability is improved, but the step board portion may bend under worker weight when intermediate parts are not supported
Solution Approach 1:
The reinforcement member extends in the width-wise direction (transverse to the longitudinal direction of the step board), adding structural support in a different dimension. This perpendicular reinforcement prevents bending while allowing the step board to span longer distances in the longitudinal direction, thus resolving the contradiction between increased working area and maintained stability.
2Loss of time
If the step board portion is made long to reduce the number of support structures, then the construction time is reduced, but the bending resistance decreases
Solution Approach 1:
The reinforcement member is divided into multiple segments connected by coupling portions, with extensions spaced apart in the vertical direction. This segmented structure provides bending resistance throughout the length of the step board without requiring continuous intermediate support structures, allowing longer step board spans that reduce construction time while maintaining strength.
3Ease of manufacture
If the reinforcement member uses separate components for extensions and coupling portions, then the ease of assembly is improved, but the overall strength is reduced
Solution Approach 1:
The extensions and coupling portions are integrally formed as a single piece, merging what could be separate components into one unified reinforcement member. This integral construction eliminates weak points at connection joints and provides continuous structural support, maximizing the bending resistance and overall strength of the reinforcement member.

AI summary
A scaffold provided with a running board part and a reinforcing member which is attached to at least one end of the running board part in the width direction of the running board part. The reinforcing member has a pair of extension parts which extend in the longitudinal direction of the running board and which are disposed apart from each other in the vertical direction, and a plurality of connecting parts which are disposed at intervals in the longitudinal direction and which connect the pair of extension parts.
