Integrated Load-Transferring Connecting Element for Stair Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing prefabricated stairs are time-consuming and costly due to the need for separate lifting brackets to lift the stair unit out of the mold and position it next to the stair landing, and require additional adjustments to ensure horizontal alignment without level differences.
Innovation Solution
A load-transferring connecting element with an elongated box-shaped main body, featuring an attachment area for lifting equipment and an adjusting device to regulate height differences, allowing for integrated lifting and alignment of stair units with stair landings, eliminating the need for separate lifting brackets and ensuring flush installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate lifting brackets are used to lift the stair unit out of the mold and position it next to the stair landing, then the stair unit can be installed, but the process becomes time-consuming and costly
Solution Approach 1:
The patent combines the lifting bracket and the connecting element into a single integrated component. The connecting element features a box-shaped structure with an opening that serves as both the lifting bracket (for attaching lifting cables) and the connecting element (for receiving the stair nose). This eliminates the need for separate lifting brackets, streamlining the installation process and reducing time consumption.
2Ease of operation
If separate lifting brackets are used for lifting and positioning, then the stair unit can be installed, but additional costs are incurred
Solution Approach 1:
The lifting bracket functionality is merged into the connecting element itself. The box-shaped connecting element includes an opening that receives the stair nose and also serves as the attachment point for lifting cables during manufacturing and installation. This reduction in component count simplifies the overall system and reduces costs.
Solution Approach 2:
The connecting element performs multiple functions: it serves as both the lifting bracket (for attaching lifting cables during manufacturing and installation) and the connecting element (for receiving and securing the stair nose). This multi-functionality eliminates the need for separate dedicated lifting brackets, reducing device complexity and cost.
3Manufacturing precision
If washers or adjustable screws are used to adjust horizontal positioning, then alignment with the stair landing is achieved, but the process becomes more complex and time-consuming
Solution Approach 1:
The connecting element incorporates an adjustable mechanism that allows dynamic regulation of the stair unit's horizontal position relative to the stair landing. This adjustable feature enables precise alignment to be achieved during installation without requiring complex external adjustment mechanisms, thereby maintaining manufacturing precision while controlling device complexity.

AI summary
A load-transferring connecting element establishes a connection between a first building element and a second building element. The load-transferring connecting element is adapted for transfer of force between the first and second building elements. The load-transferring connecting element includes an elongated box-shaped main body. A first end portion of the load-transferring connecting element is arranged for attachment into the first building element with a remaining second end portion of the load-transferring connecting element positioned so as to project from the first building element. The second end portion is adapted for being received in a cavity arranged in the second building element. The second end portion of the load-transferring connecting element is provided with an attachment area for attaching lifting equipment for handling of the first building element.
