Mounting Plates for Window Frame Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for producing airtight and waterproof connections between window or door frames and external walls are time-consuming and prone to errors, especially when applying a bituminous layer at the lower corners, which can lead to cracks and reduced durability of the waterproofing system.
Innovation Solution
The use of mounting plates in the connection area facilitates the application of the bituminous layer by ensuring a uniform plane and easy access, reducing the risk of faulty connections and enhancing the sealing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bituminous layer is applied directly to the frame and sealing tape, then the waterproofing function is achieved, but the process becomes time-consuming and error-prone with cracks and faulty connections
Solution Approach 1:
A mounting plate is introduced as an intermediary element between the frame and the bituminous layer. The mounting plate provides a stable, pre-prepared surface that facilitates reliable application of the bituminous layer while simplifying the installation process. The plate serves as a mediator that ensures both waterproofing reliability and ease of manufacture.
2Manufacturing precision
If the bituminous layer is applied carefully to ensure tightness, then the sealing quality improves, but the process becomes excessively time-consuming
Solution Approach 1:
The mounting plate is prepared in advance with the necessary surface characteristics (flatness, adhesion properties) before the bituminous layer is applied. This preliminary preparation eliminates the need for time-consuming on-site surface preparation and ensures high sealing precision from the start, thereby increasing installation speed without compromising quality.
3Duration of action of stationary object
If the bituminous layer is applied at the lower corners without mounting plates, then the structure remains simple, but cracks occur and durability is reduced
Solution Approach 1:
The connection structure is segmented into distinct functional elements: the frame, the mounting plate, and the bituminous layer. This segmentation allows each element to perform its specific function optimally - the mounting plate provides structural support and a stable base, while the bituminous layer focuses on waterproofing, thereby enhancing durability without excessive complexity.
4Ease of manufacture
If the outer seal surface is made uneven to accommodate direct application, then the application process is simpler, but the seal quality deteriorates with cracks and faults
Solution Approach 1:
The mounting plate serves as an intermediary that provides a uniformly prepared surface for the bituminous layer. This intermediate surface ensures both ease of application and high seal uniformity, as the plate can be factory-prepared with the necessary surface characteristics before installation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method simplifies the application of the bituminous layer, reduces the risk of cracks, and ensures a high-quality seal that meets the highest sealing requirements, particularly by shifting the scarfing area to the mounting plate, thus improving the durability and effectiveness of the waterproofing system.
Implementation Method 1
joint sealing tapes, ie tape-shaped flexible window connection foils provided with adhesive layers... A double-sided adhesive tape based on acrylate is usually used for this purpose... the window connecting foils usually have an adhesive strip provided with a butyl-based adhesive
Implementation Method 2
The building connection joints between the window frame and the structure are filled with assembly foam - which fulfills the insulating function
Implementation Method 3
this seal is supplemented on the outside by a bituminous layer, which can be produced as a coat of paint, using webs or equivalent materials

AI summary
The method involves rotatably gluing joint sealing tapes (3) on frame profiles before installing a frame (4). A window frame is inserted into a window opening and connected with a masonry part. Parts of the joint between window or door frames and building structure are sealed by bituminous layer made of painting, trajectories or homogeneous materials. Mountable metal sheets (1) are attached to the frame to which end regions of the bituminous layer adheres. The ends of the bituminous layer are connected with the metal sheets. An independent claim is also included for a mountable metal sheet.
