Wall Formwork Sealing System with Detachable Anchor Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall formwork systems lack a flexible and efficient sealing solution for anchor systems, leading to concrete bleed and increased maintenance due to the need for multiple sealing assemblies and destructive dismantling methods.
Innovation Solution
A wall formwork system with a sealing system that includes detachable anchor seals and closure caps connected via an adapter strip, utilizing latching connections and bayonet locks for easy assembly and reusability, reducing interfaces with concrete to minimize leakage and uneven surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple different sealing assemblies are used for different anchor systems, then sealing reliability is improved, but device complexity and storage requirements increase
Solution Approach 1:
The adapter is designed with a universal interface that can accommodate different anchor systems (e.g., wedge anchors, expansion anchors, chemical anchors) while maintaining the same sealing mechanism. The adapter strip provides multiple anchor holes that can accept various anchor types, and the closure cap with its conical sealing surface works with all of them, eliminating the need for multiple specialized sealing assemblies.
2Ease of operation
If destructive dismantling methods are used for sealing sleeves, then ease of removal is improved, but loss of the sealing component occurs
Solution Approach 1:
The sealing system is divided into separate functional components: the adapter (which remains in the formwork), the anchor seal (which provides the sealing function), and the closure cap (which closes the anchor hole). This segmentation allows the anchor seal and closure cap to be removed and reused while the adapter stays embedded in the formwork facing, eliminating the need for destructive dismantling of an integrated sealing sleeve.
3Reliability
If anchor seals and closure caps are permanently fixed in the formwork, then sealing reliability is improved, but adaptability for different anchor systems decreases
Solution Approach 1:
The connection between the anchor seal/closure cap and the adapter is designed to be dynamically adjustable rather than permanently fixed. The adapter features a detachable connection mechanism that allows the sealing components to be removed and reinstalled with different anchor systems, providing both reliability during use and adaptability for conversions between anchor types.
4Adaptability or versatility
If multiple interfaces are provided between sealing components and formwork, then adaptability is improved, but leakage risk increases
Solution Approach 1:
The adapter serves as an intermediary component between the formwork facing and the anchor seal/closure cap assembly. It provides a standardized interface that reduces the number of direct contact points between different components, thereby minimizing potential leakage paths while maintaining adaptability through its detachable connection design.

AI summary
A wall formwork with a sealing system, in particular for closing an anchor hole of the wall formwork or for sealing an anchor rod in an anchor hole of the wall formwork, which comprises an anchor seal and a closure cap, and which is made in such a way that the anchor seal and the closure cap can be detachably connected to the anchor hole or an adapter providing the anchor hole. By means of the invention, it can be made possible that one or more anchor seals and closure caps of the sealing system can be particularly easily removed from the wall formwork and re-used, and that a particularly small maintenance expenditure for the wall formwork can be achieved.
