Plaster Sealing Strip With Pivoting Leg For Joint Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plaster sealing strips face challenges in providing a stable, reliable, and inconspicuous seal for joints between building components and walls, especially with movement compensation and ease of installation and plastering, while maintaining a visually appealing finish.
Innovation Solution
A plaster sealing strip with a profile body featuring a base leg for attachment and a plastering leg for embedding in the plaster, along with a pivot leg for secure positioning and easy detachment, ensuring stable attachment and movement compensation, and a design that minimizes visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the plaster sealing strip is embedded in the building wall for stable fastening, then the reliability of the connection is improved, but the complexity of installation increases
Solution Approach 1:
The plaster sealing strip is divided into multiple legs (base leg, plaster leg, and pivot leg) that can be independently positioned and function. This segmentation allows each leg to be optimized for its specific function while simplifying the overall installation process through modular positioning.
Solution Approach 2:
The pivot leg is provided as a preliminary positioning element that can be easily attached and detached during installation. This preliminary action allows the sealing strip to be securely positioned before final plastering, ensuring proper alignment without complex embedding procedures.
2Stability of the object's composition
If the plaster sealing strip is supported on both sides over a large area, then the positioning stability is improved, but the visibility from the outside increases
Solution Approach 1:
Different legs of the plaster sealing strip have different functional qualities: the base leg provides support on the building element side, the plaster leg provides embedding in the wall, and the pivot leg provides positioning support. This local differentiation allows stable positioning without excessive visible protrusion.
Solution Approach 2:
Instead of having the entire sealing strip visible and supported externally, the invention inverts the approach by providing support through the pivot leg that can be positioned and then detached, leaving only the necessary minimal visible portion while maintaining stability during installation.
3Ease of operation
If the pivot leg is designed for easy detachment, then the ease of operation is improved, but the reliability of the seal may be compromised
Solution Approach 1:
The pivot leg is designed with dynamic characteristics - it can be easily attached and detached during installation, but once the sealing strip is plastered in place, the system becomes fixed and stable. This dynamic design allows easy operation during installation while maintaining reliability in the final installed state.
Solution Approach 2:
The easy detachment feature of the pivot leg serves as a preliminary action during installation only. After the sealing strip is properly positioned and plastered, the pivot leg remains as part of the fixed structure, ensuring that the seal reliability is not compromised in the final state.

AI summary
A plaster sealing strip has a profile body with a base leg aligned along an insertion direction for fastening and a plaster leg for plastering in, the plaster leg projecting from the base leg in a normal direction perpendicular to the insertion direction. On a side of the base leg facing away from the plaster leg, a recess for a sealing tape is formed, which is bounded in the normal direction by a base section, in the insertion direction by a rear wall section, and against the insertion direction by a front wall section of the base leg.The profile body further comprises a pivoting leg with a retaining section and a cover section, which is pivotally attached to the base leg and can be pivoted from a deflected position, in which a sealing tape can be inserted into the aforementioned receptacle, to a mounting position in which the retaining section limits the receptacle in the opposite direction to the normal direction and the cover section projects beyond the base leg in the opposite direction to the insertion direction. In the mounting position, the retaining section and/or the cover section of the pivoting leg are/are inclined relative to the insertion direction.
