Wood Construction Bracket with Suspension Hook and Notch Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for joining wood-based construction elements, such as those described in Swedish patent SE 515784 and US2002/0100235, face limitations in motion and load-bearing capacity due to grooves and weight constraints, and lack simultaneous locking in both vertical and horizontal directions.
Innovation Solution
The proposed solution involves using I-beam construction elements with wood-fibre sheet webs, pressure, and tensile flanges, along with a lamellar board plate and suspension brackets, forming a tongue-and-groove joint with sound-insulating notches to ensure precise fitting and locking in both directions, utilizing materials like solid wood, LVL, or glulam for enhanced structural integrity.

Engineering Contradiction Analysis
1Strength
If grooves and projections are used to lock construction elements, then the elements can be joined together, but the motions of the modules are limited and the load-bearing capacity is restricted
Solution Approach 1:
The connection system is divided into separate functional components: suspension brackets for vertical support, notches for horizontal positioning, and separate locking mechanisms. This segmentation allows each component to optimize its specific function without compromising the others, enabling both high load-bearing capacity and motion flexibility during assembly.
Solution Approach 2:
Sound-insulating material is introduced as an intermediary element within the notches and between connection components. This mediator serves multiple functions: it enables precise horizontal fitting through the notch geometry, provides vibration absorption to enhance load-bearing capacity, and allows for adjusted motion control during the assembly process.
2Reliability
If traditional joining methods are used, then assembly is possible, but simultaneous locking in both vertical and horizontal directions is not achieved
Solution Approach 1:
Multiple locking functions are merged into an integrated connection system where suspension brackets provide vertical locking while notches provide horizontal locking simultaneously. The sound-insulating material within the notches enhances both directions of locking stability, achieving reliable multi-directional fixation without requiring separate complex mechanisms for each direction.
Solution Approach 2:
The notches serve multiple functions: they provide horizontal positioning, contain sound-insulating material for vibration absorption, and work together with suspension brackets to achieve simultaneous vertical and horizontal locking. This multi-functionality reduces the need for additional specialized components, maintaining device simplicity while enhancing reliability.
3Manufacturing precision
If precise fitting of construction elements is required, then assembly accuracy is improved, but assembly time and complexity increase
Solution Approach 1:
The notches are pre-formed with precise geometry during manufacturing, and sound-insulating material is pre-installed within them. This preliminary preparation ensures that when modules are assembled, the precise fitting is achieved immediately through the pre-configured notches, without requiring additional on-site adjustment or complex alignment procedures, thus reducing assembly time.

AI summary
The invention concerns an arrangement for joining two construction elements (1A,1B) of wood-based material constructed from supporting battens (2) and at least one plate (9), of which one construction element (1A) is a component of a load-carrying wall formed by at least two such wall elements (1A,1A.1), stacked on each other, one on top of the other, while the second construction element (1B) is a component of an essentially horizontal floor construction that is supported by the said wall. In order to facilitate the fitting of the elements, the arrangement comprises a bracket (14) that is arranged at an end wall (13) of the floor construction element (1B), and which bracket has at one of its ends a hook-shaped part (16b,19) from which the floor construction element is suspended resting on a first edge at an end part (20) of one (1A.1) of the wall elements.
