Flexible Surface Sealing Element for Building Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface sealing solutions for buildings are inflexible, fail to form a uniform bond with curved surfaces, and are not effective in preventing moisture and gas ingress, leading to structural damage over time.
Innovation Solution
A surface sealing element comprising a flat plastic film carrier with a textile layer impregnated adhesive and a grid layer of crossing, rod-shaped elements, which forms both mechanical and adhesive bonds with fresh concrete, ensuring a reliable seal against water and gas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a rigid plastic plate with lattice structure is used as surface seal, then manufacturing precision is improved, but adaptability deteriorates because it cannot seal corners or conform to curved surfaces
Solution Approach 1:
The patent replaces rigid plastic plates with flexible plastic films as the carrier for the surface sealing element. This flexible film can conform to curved surfaces and corners while maintaining the sealing function, directly resolving the contradiction between manufacturing precision and adaptability to curved surfaces.
2Reliability
If surface sealing elements are applied discontinuously with grid cells, then reliability is improved by preventing water propagation, but strength deteriorates due to poor adhesion to fresh concrete
Solution Approach 1:
The patent applies the adhesive layer continuously over the entire surface of the textile layer rather than discontinuously in grid cells. This continuous application ensures uniform contact and strong adhesion to fresh concrete across the entire sealing element, while the fleece structure still provides leak prevention by allowing concrete penetration and bonding.
Solution Approach 2:
The patent uses a composite structure consisting of a plastic film carrier, a textile layer (fleece), and an adhesive layer. This composite material combines the impermeability of the plastic film with the concrete-bonding capability of the adhesive-impregnated textile, achieving both leak prevention and strong adhesion simultaneously.
3Ease of operation
If a fleece layer is used to allow concrete penetration, then ease of operation is improved, but reliability deteriorates because water can accumulate and spread between the fleece and concrete
Solution Approach 1:
The continuous adhesive layer applied over the entire textile surface ensures that there are no gaps or discontinuities where water could accumulate and spread. This continuous bonding creates reliable protection from the rear while maintaining the ease of concrete penetration and bonding provided by the fleece structure.
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
The solution provides a flexible, easy-to-handle surface sealing element that effectively prevents moisture and gas ingress, forming a strong and permanent bond with concrete, thus preventing structural damage and ensuring long-term integrity.
Implementation Method 1
a textile layer (3) which is stuck onto the flat carrier (2) and is impregnated with adhesive (5), and a lattice layer (4) which is arranged on the surface of the textile layer (3) which faces away from the flat carrier (2)
Implementation Method 2
The plastic film prevents gas and/or water from penetrating, so it is essentially a gas-tight and/or water-tight flat carrier (2)
Implementation Method 3
A surface sealing element has a flat carrier (2), a textile layer (3) which is stuck onto the flat carrier (2) and is impregnated with adhesive (5), and a lattice layer (4) which is arranged on the surface of the textile layer (3)
