Acrow Prop Reinforcement Sleeve for Buckling Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Acrow props face reduced resistance to buckling at maximum length and under high loads, necessitating increased numbers to ensure structural integrity, leading to higher costs and installation times.
Innovation Solution
A reinforcement device comprising a tubular sleeve that slides over the inner tube of the acrow prop, providing attachment means and enhancing resistance to buckling through increased load-bearing capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the length of the prop is increased to cover a wider range, then the versatility and adaptability of the prop is improved, but the resistance to buckling deteriorates
Solution Approach 1:
The prop is divided into two telescopic tubes (inner tube and outer tube) that can move relative to each other, allowing the prop to achieve different lengths by extending or retracting the inner tube within the outer tube. This segmentation enables versatility in length adjustment while maintaining structural integrity through the reinforced tubular sleeve that strengthens the joint between segments.
2Reliability
If the number of props is increased to ensure structural integrity under high loads, then the reliability and load-bearing capacity is improved, but the cost and installation time increase
Solution Approach 1:
The prop combines two different materials: a metallic tubular structure for the telescopic tubes and a fibrous reinforcement material (such as carbon fiber or glass fiber) for the tubular sleeve. This composite construction increases the load-bearing capacity and buckling resistance of each individual prop, allowing fewer props to be used while maintaining structural integrity and reducing installation time.

AI summary
The invention relates to a construction post comprising an outer tube, an inner tube and a piece for securing the tubes together. The outer tube comprises a tightening nut at the upper end, the inner tube being able to move inside the outer tube and comprising a plurality of pairs of holes distributed along the length thereof. The holes are arranged in diametrically opposite positions of the inner tube, the securing piece passing through one of the pairs of holes of the inner tube so as to prevent relative movement between the inner and outer tubes. The post is characterised in that it has a reinforcement device comprising a tubular sleeve able to slide along the outside of the inner tube of the construction post, the tubular sleeve comprising means for securing to the construction post.
