Detachable Fastening Plate for Eaves Flashing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nail fastening of eaves plates is difficult to replace without damaging the eaves board, as detachment can cause damage to both the eaves plate and board.
Innovation Solution
A detachable fastening plate with a projection and inclined surface that can be pressed into folds of the eaves plate, providing a stable and form-fitting connection, allowing for secure fixing and stabilization of the eaves flashing while enabling easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nail fastening is used to attach eaves plate to eaves board, then secure attachment is achieved, but replacement becomes difficult and may damage the eaves board
Solution Approach 1:
The fastening system is divided into separate components: a fastening plate with connecting means and the eaves plate itself. The connecting means (protrusions and recesses) can be separated and reattached, allowing the eaves plate to be removed and replaced without damaging the eaves board, while still providing secure attachment during use.
Solution Approach 2:
The fastening system transitions from a static permanent nail connection to a dynamic reversible connection. The connecting means with protrusions and recesses allow the eaves plate to be attached securely during normal operation, but can be detached and reattached when replacement is needed, providing both security and replaceability.
2Ease of manufacture
If regular rows of broadhead pins are used for fastening, then simple installation is achieved, but form-fitting stability is insufficient
Solution Approach 1:
The connecting means feature asymmetric protrusions and corresponding recesses that provide directional stability. The protrusions have specific shapes (such as L-shaped or T-shaped profiles) that fit into matching recesses, creating a form-fitting connection that prevents unwanted movement while maintaining simple installation through the offset section.
Solution Approach 2:
The offset section acts as an intermediary element that simplifies installation. This section extends beyond the main plate body and can be inserted into the eaves plate first, guiding the main body into proper position and making the overall assembly process simpler while the protrusions provide the form-fitting stability.

AI summary
The invention relates to a fastening means (100) for a drip edge (30) on a roof, preferably on a drip edge board, wherein the drip edge (30) is provided with at least one fold. In order to ensure the replacement of the drip edge (30) and at the same time to create a stable connection between the fastening means (100) and the drip edge (30), the invention proposes that the fastening means (100) be a plate (10) that can be detachably connected to the drip edge (30), wherein the plate (10) has connecting means (11, 12) that can project into the drip edge and can be pressed or slid into at least one fold (23, 26) of the drip edge (30). The invention relates to a fastening means (100) for a drip edge strip (30).To create a stable connection between fastening means (100) and an eaves strip (30), which also allows the replacement of the eaves strip, the invention proposes a plate (10) that can be detachably connected to the eaves strip (30), wherein the plate (10) has connecting means (11, 12) that can be pressed or inserted into at least one fold (23, 26) of the eaves strip (30).
