Segmented Plaster Sealing Strip for Thick Render Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plaster sealing strips are not designed to support the application of thick base plaster layers and additional plaster layers, particularly in thick-layer render systems.
Innovation Solution
A plaster sealing strip comprising a base profile and an additional profile, where the base profile has a plaster leg for embedding in a base plaster layer and an additional profile with a plaster leg for embedding in an additional plaster layer, allowing for stable attachment and support of thick plaster layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional plaster sealing strips are used, then the sealing function is provided, but they cannot support thick base plaster layers and additional plaster layers
Solution Approach 1:
The plaster sealing strip is divided into a base profile and an additional profile that are designed separately and can be manufactured independently. The base profile provides support for the base plaster layer, while the additional profile provides support for the additional plaster layer, allowing each segment to be optimized for its specific function and collectively support thick multi-layer plaster systems
Solution Approach 2:
The invention transitions from a single-profile design to a multi-profile design by adding the additional profile. This dimensional expansion in the product structure enables the system to support multiple plaster layers with different requirements, resolving the contradiction between plaster layer thickness and support capability
2Quantity of substance
If a thick base plaster layer is applied, then the sealing and insulation performance is improved, but conventional sealing strips cannot provide stable embedding
Solution Approach 1:
The base profile is designed as a separate component with a plaster leg specifically optimized for embedding in the thick base plaster layer. This segmentation allows the base profile to provide stable anchoring in the base layer while the additional profile handles the additional layer, ensuring embedding stability throughout the thick plaster system
Solution Approach 2:
The base profile and additional profile have different local structures optimized for their respective functions. The base profile's plaster leg is designed with specific characteristics for embedding in the base plaster layer, while the additional profile's plaster leg is designed for the additional layer, providing locally optimized embedding stability for each plaster layer
3Reliability
If separate base profile and additional profile are used, then support for thick plaster layers is enabled, but device complexity increases
Solution Approach 1:
While the plaster sealing strip is segmented into base profile and additional profile, these segments are designed to be relatively simple in structure, manufactured separately but assembled together. The segmentation enables specialized functionality for thick-layer systems without requiring overly complex individual components, balancing reliability improvement with manageable device complexity

AI summary
A plaster sealing strip for the structural connection of a building element, in particular a window or a door, to a building wall comprises a base profile and an additional profile. The base profile has a profile body extending in a first longitudinal direction, which comprises a base leg oriented along a base direction for fastening to the building element and/or to the building wall and a plaster leg for plastering into a base plaster layer on the building wall, wherein the plaster leg protrudes from the base leg in a normal direction oriented at least substantially perpendicular to the base direction. The additional profile has a profile body extending in a second longitudinal direction, which comprises a plaster leg for plastering into an additional plaster layer on the base plaster layer.It is provided that the base profile has a coupling extension and the additional profile has a coupling receptacle or, conversely, the base profile has a coupling receptacle and the additional profile has a coupling extension, wherein the base profile and the additional profile are designed to be coupled to one another by inserting the coupling extension into the coupling receptacle in such a way that the cleaning leg of the base profile and the cleaning leg of the additional profile are arranged at a distance from one another and are aligned at least substantially parallel to one another.
