Adjustable Anchor Bracket for Prefabricated Wall Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connections between prefabricated house walls and concrete slabs are insufficient in ensuring horizontal alignment and are labor-intensive, with protruding tie rods risking damage during transport and unable to compensate for height differences between the slab and wall edges.
Innovation Solution
A separate adjustment bracket with a finely adjustable horizontal leg connected to the tie rod allows optimal adaptation to the concrete slab, ensuring precise alignment and secure fastening without protruding parts, using a slot and fixing pins for adjustment and a pressure plate for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the horizontal leg of the tie rod is connected directly to the concrete slab, then the hold of the sleepers on the concrete slab is improved, but the unevenness of the top of the concrete slab is transferred to the threshold of the wall
Solution Approach 1:
An adjustment bracket is introduced as an intermediary component between the tie rod's horizontal leg and the concrete slab. This bracket includes a vertical leg connecting to the tie rod and a horizontal leg with a fastening surface for attachment to the concrete slab, enabling independent adjustment of the connection point to compensate for slab unevenness while maintaining secure fastening
Solution Approach 2:
The adjustment bracket is designed with adjustable features that allow the connection point to be dynamically positioned. The bracket can be adjusted in the direction of the concrete slab to accommodate varying heights and unevenness, transforming a static rigid connection into a dynamically adaptable connection that maintains both strength and precision
2Strength
If protruding parts of the tie rod are used for connection, then the connection to the concrete slab is secured, but damage to other wall elements during transport and loading/unloading may occur
Solution Approach 1:
The function of securing the connection to the concrete slab is extracted from the tie rod itself and transferred to the adjustment bracket. The tie rod is shortened or modified to remove protruding parts, while the adjustment bracket provides the necessary connection interface with its horizontal leg that can be flush-mounted or recessed, eliminating the harmful protruding elements
Solution Approach 2:
The adjustment bracket serves as a mediator that separates the structural connection function from the tie rod. It provides the secure attachment to the concrete slab through its horizontal leg while allowing the tie rod to remain compact and non-protruding, thus protecting wall elements during handling
3Device complexity
If the tie rod connection is used without adjustment mechanisms, then the structure is simple, but the height difference between the upper edge of the concrete slab and the lower edge of the wall cannot be compensated
Solution Approach 1:
The adjustment bracket incorporates adjustable features that enable dynamic positioning to compensate for height differences. The bracket can be adjusted in the direction of the concrete slab through mechanisms such as slots with adjustment projections or threaded connections, allowing the connection point to be precisely positioned to match varying slab heights while maintaining a relatively simple overall structure

AI summary
The tension rod has a wall-mounted anchor plate (10) which is flush with the bottom of the wall and has a horizontal mounting plate (20) connectable to the concrete slab. The height of horizontal mounting plate at the anchor plate is vertically adjustable and connectable using laterally displaceable control panel (12).
