Pivotable Plastering Strip Reinforcement Fabric
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The attachment of plaster strips in thermal insulation composite systems is often difficult, leading to damage and moisture penetration, which can cause damage to the plaster, thermal insulation, and building components like window or door frames.
Innovation Solution
A plug-in end strip with a pivotable reinforcement fabric section made of plastic or glass fiber, coated with an alkali-resistant material, allows for easier application and ensures better adhesion and crack resistance by pivoting between application and plastering positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the reinforcement fabric section is rigidly attached to the plaster strip, then the adhesion of plaster to substrate is improved, but the application process becomes difficult and the plaster strip is damaged
Solution Approach 1:
The reinforcement fabric section is pivotally mounted to allow it to be moved between a first position (for application of reinforcing material) and a second position (for plastering). This dynamic positioning resolves the contradiction by enabling easy application while maintaining adhesion strength.
Solution Approach 2:
The plaster strip is divided into functional sections: a fixed base portion and a movable reinforcement fabric section. This segmentation allows the reinforcement fabric to be independently positioned, facilitating easy application of reinforcing material while preserving the adhesion function when in the plastering position.
2Reliability
If the reinforcement fabric section is rigidly attached to the plaster strip, then the plaster is permanently free of cracks, but the application process causes damage to the plaster strip
Solution Approach 1:
The pivotal mounting allows the reinforcement fabric section to be dynamically positioned away from the plaster strip during application, preventing damage. When pivoted to the second position, it provides the same crack resistance as a rigidly attached fabric, thus maintaining reliability without compromising ease of operation.
Solution Approach 2:
The reinforcement fabric section is preliminarily positioned away from the plaster strip to avoid interference during the application of reinforcing material. This preliminary positioning prevents damage during installation while the fabric remains ready to provide crack resistance when needed.
3Object-affected harmful factors
If the plaster strip is used at transition positions, then moisture penetration is prevented, but the attachment process is difficult and results in suboptimal reinforcement
Solution Approach 1:
The movable reinforcement fabric section enables easy attachment at transition positions by allowing the fabric to be positioned away during the attachment process. This dynamic positioning ensures optimal reinforcement is achieved without the difficulties associated with rigidly attached fabrics at complex installation locations.
4Ease of operation
If the reinforcement fabric section is moved away during application, then the application of reinforcing material is simplified, but the attachment mechanism becomes more complex
Solution Approach 1:
A simple pivotal mounting mechanism is used to enable the reinforcement fabric section to be moved away during application. This minimal mechanical complexity achieves the goal of simplified reinforcing material application while avoiding overly complex attachment mechanisms.
Solution Approach 2:
The reinforcement fabric section itself acts as a flexible element that can be easily pivoted and repositioned. This flexibility simplifies the attachment mechanism compared to rigid systems, as the fabric's own properties enable the movement needed for easy application.

AI summary
A plastering strip (2) according to the invention, made of plastic or plastic composite material, comprises a mesh-like reinforcing fabric section (20) attached to it, in particular made of plastic and/or glass fiber or fiberglass fabric, for embedding in or under a plaster layer, in particular a plaster layer on thermal insulation (28) of a building wall. The reinforcing fabric section (20) is pivotably attached to the plastering strip such that it can pivot between an embedded plaster position and a pivoted position.
