Formwork Anchor Sealing Structure for Easier Tie Rod Seal Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vertical formworks face challenges in preventing concrete leakage due to deterioration of sealing elements, which are often difficult to replace and require complex sealing arrangements within the formwork panels.
Innovation Solution
The design positions sealing elements at the end of the anchor, allowing for easier replacement and accessibility, with a single sealing element providing both the seal between the anchor and the formwork panel and the tie rod, utilizing a sealing ring and end ring configuration for effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing means is arranged inside the anchor, then sealing effectiveness is improved, but accessibility for replacement deteriorates
Solution Approach 1:
The sealing means is divided into a first sealing element arranged in the outer part of the anchor for sealing with the formwork panel, and a second sealing element arranged inside the anchor for sealing with the tie rod. This segmentation allows the first sealing element to be easily accessible for replacement while maintaining effective sealing at both critical locations.
2Reliability
If multiple sealing elements are used inside the anchor, then sealing coverage is improved, but device complexity increases
Solution Approach 1:
The first and second sealing elements work together in a coordinated manner, where the first sealing element seals the outer interface between the anchor and formwork panel, while the second sealing element seals the inner interface between the anchor and tie rod. This merging of sealing functions at different locations provides comprehensive sealing coverage without requiring multiple complex sealing mechanisms within the same location.
3Stability of the object's composition
If sealing means is arranged in the formwork panel, then sealing stability is improved, but ease of replacement deteriorates
Solution Approach 1:
The sealing means is extracted from the formwork panel and integrated into the anchor structure. The first sealing element is arranged in the outer part of the anchor, allowing it to be easily accessed and replaced by simply removing the anchor from the formwork panel. This extraction maintains sealing stability through proper sealing geometry while dramatically improving replaceability.

AI summary
An anchor for a vertical formwork having two formwork panels facing one another. The anchor is suitable for being fixed to one of the formwork panels. The anchor includes a housing for receiving a part of a tie rod fixing the two formwork panels and a single sealing element configured for sealing the anchor with respect to the formwork panel in which it is fixed and with respect to the tie rod housed in the housing of the anchor.
