Stabilizer Posts for Scaffold Hoist Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffold hoist systems lack stability when used on walls without exposed studs, posing safety risks for construction workers.
Innovation Solution
A stabilizer post system comprising L-shaped angle inserts and spacers with adjustable locking mechanisms, allowing attachment to walls without studs, providing stability for scaffold hoists through adjustable upper and lower slide posts and locking means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If horizontal bars are attached to wall studs for stability, then scaffold hoist stability is improved, but the system becomes inapplicable to walls without exposed studs
Solution Approach 1:
The patent introduces angle iron inserts as intermediary elements that are first attached to the wall surface (using anchors or adhesive when studs are not exposed), and then the horizontal stabilizer bars are attached to these inserts. This intermediary layer enables the stabilizer system to work on walls without exposed studs, resolving the contradiction between stability and adaptability to different wall types.
2Ease of manufacture
If fixed stabilizer bars are used, then installation is simple, but the system cannot be adjusted for different heights and applications
Solution Approach 1:
The patent employs telescopic or adjustable-length stabilizer bars that can be extended or repositioned along the angle iron inserts to different heights and positions. This dynamic adjustment capability allows the same stabilizer post system to be adapted for various scaffold heights and applications while maintaining relatively simple installation through the standardized angle iron attachment system.
3Stability of the object's composition
If additional wall attachment points are created for stabilizers, then stability is improved, but wall integrity may be compromised
Solution Approach 1:
The angle iron inserts are pre-attached to the wall surface using minimal penetration points (anchors or surface adhesive), creating a stable base layer before the stabilizer bars are attached. This preliminary action distributes the load across the angle iron rather than requiring multiple direct wall attachments, thereby maintaining wall integrity while achieving stable stabilizer attachment.

AI summary
This invention relates to a stabilizer post for a scaffold hoist comprising a post extending from an upper end to a lower end, an L-shaped upper angle insert comprising an upper contact plate extending down to a substantially perpendicular upper insert plate, an L-shaped lower angle insert comprising a lower contact plate extending up to a substantially perpendicular lower insert plate, and wherein the upper angle insert is attached adjacent to the upper end of the post so that the upper insert plate is below the upper insert plate and substantially perpendicular to the post and the lower angle insert is attached at the lower end of the post so that the lower insert plate above the lower contact plate and substantially perpendicular to the post, and the lower contact plate and the upper insert plate are substantially parallel to one another. The stabilizer post is attached to a wall by inserting the lower insert plate into a lower wall cut, inserting the upper insert plate into an upper wall cut, and attaching the lower insert plate to the bottom plate and the upper insert plate to the top plate.
