Scaffold Pole Height Adjustment via Threaded Rod and Nut
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffolding support devices cannot be adjusted in height after installation, posing safety risks and inefficiencies during construction, as they require on-site assembly or welding, which is both unsafe and costly.
Innovation Solution
A support device with a metal connecting pipe and threaded rod system that allows for height adjustment via a rotatable height-adjusting nut, enabling the connecting pipe to be adjusted in height relative to the threaded rod, even after initial installation, using a manually operable mechanism for easy height adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a support device is designed with a fixed connecting pipe and threaded rod assembly, then the structure is simple and easy to manufacture, but the height cannot be adjusted after installation
Solution Approach 1:
The support device transitions from a fixed structure to a dynamically adjustable one by incorporating a height-adjusting nut that can be rotated along the threaded rod. This allows the connecting pipe's height position to be changed relative to the threaded rod, enabling post-installation height adjustment while maintaining structural integrity through the threaded connection mechanism.
2Adaptability or versatility
If on-site assembly and welding is performed for scaffolding support structures, then custom height requirements can be met, but safety risks and costs increase significantly
Solution Approach 1:
The support device is divided into separable components: a connecting pipe, a threaded rod, and a height-adjusting nut. This segmentation allows the components to be assembled using simple screw connections rather than welding, eliminating the safety risks associated with on-site welding while still enabling custom height adjustments through the rotatable nut mechanism.
3Adaptability or versatility
If on-site welding and custom assembly is performed, then specific height requirements can be met, but construction time and costs increase
Solution Approach 1:
The support device components are designed with pre-configured threading and connection features that allow for rapid assembly without requiring on-site welding or custom fabrication. The standardized threaded rod and height-adjusting nut enable workers to quickly achieve the required height by simply rotating the nut, significantly reducing construction time and improving productivity compared to traditional welding methods.

AI summary
The invention relates to a supporting device (10) of metal for suspending a hanging scaffold (35) or another hanging structure. The supporting device (10) comprises a scaffold pole (11) having a welded-on sheet metal structure which forms a connection head (12) and which serves as a receptacle for a threaded bar part (53) of a threaded bar (13) having a height-adjustment nut (14) screwed thereon. The height of the scaffold pole (11) can be changed using the height-adjustment nut (14) even still with the hanging scaffold (35) suspended or with another hanging structure suspended, that is to say retroactively.
