J-Shaped Bracket With Slot For Deck Floatation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deck-to-structure coupling systems fail to effectively address frost heave and deck uplift, particularly in coupling a deck to a structure while allowing for board floatation and preventing uplift.
Innovation Solution
A J-shaped bracket comprising multiple plates with a scalene right triangular plate and slots, coupled with connectors and couplers to secure the deck, allowing for horizontal alignment and floatation due to frost heave while preventing uplift.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid deck-to-structure coupling system is used, then the deck is securely fastened to the structure, but the deck cannot accommodate frost heave and board floatation
Solution Approach 1:
The bracket incorporates a slot in the fourth plate that allows vertical movement of the board relative to the structure. This dynamic feature enables the deck to accommodate frost heave and board floatation while maintaining secure attachment through the connector passing through the slot, thus resolving the contradiction between rigid security and adaptive movement.
2Strength
If multiple connectors are used to secure the bracket to the structure, then the attachment strength is improved, but the complexity of the coupling system increases
Solution Approach 1:
The bracket integrates multiple plates (first, second, third, and fourth plates) with multiple holes for connectors into a single unified component. This merging of multiple elements into one integrated bracket reduces the number of separate parts and assembly steps, thereby reducing system complexity while maintaining strong attachment through multiple connector holes.
3Adaptability or versatility
If the bracket design includes multiple plates and slots for board floatation, then the adaptability to frost heave is improved, but the manufacturing complexity increases
Solution Approach 1:
The bracket is divided into four distinct plates (first, second, third, and fourth plates) with specific geometric shapes and orientations. This segmentation allows each plate to be manufactured separately using standard metal forming processes, then joined together through welding or bolting. The slot in the fourth plate is a simple cutout that can be easily manufactured, thus maintaining ease of manufacture while achieving board floatation capability.

AI summary
A header board bracket for coupling a deck to a structure includes a brace that comprises first, second, third, and fourth plates. The second plate is coupled to and extends perpendicularly between bottoms of the first and third plates. The first plate is dimensionally longer than the third plate. The fourth plate is scalene right triangularly shaped. The fourth plate is coupled to and extends perpendicularly from the first and second plates. The third and fourth plates define a slot. Each of a plurality of holes that is positioned through the first plate is configured to insert a connector to couple the brace to a structure. A plurality of the braces is configured to couple to the structure with the braces horizontally aligned. The slots of the braces are configured to insert a board to retain the board as a deck that comprises the board floats relative to the structure.
