Solution Overview

Problem

Existing vertical formworks face challenges in preventing concrete leakage due to inadequate sealing between formwork panels, anchors, and tie rods, with sealing elements often deteriorating and being difficult to replace.

Innovation Solution

The vertical formwork design incorporates a single rubber gasket sealing element arranged at the end of the tubular extension of the anchor, which seals both the anchor to the formwork panel and the tie rod housed in the anchor, making it easier to replace and accessible for maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sealing means are arranged inside the anchor or in the formwork panel, then sealing effectiveness is improved, but maintenance difficulty increases and replacement becomes complex

Engineering Contradiction:
Improvesealing effectivenessVSAvoidsealing element replacement
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The sealing element is segmented into a modular design where it can be independently removed from the anchor assembly. The clamp mechanism allows the sealing element to be separated from the tie rod and formwork panel connection, enabling easy replacement without disassembling the entire anchor system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sealing element is extracted as a separate, removable component from the anchor assembly. The clamp is designed to hold the sealing element in place during operation but allows for straightforward removal and replacement, converting a permanently integrated sealing solution into a maintainable one.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If multiple sealing elements are used to seal both anchor to formwork panel and tie rod to anchor, then sealing completeness is improved, but device complexity increases

Engineering Contradiction:
Improvesealing completenessVSAvoidnumber of sealing elements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sealing function is merged into a single integrated sealing element that simultaneously addresses both sealing requirements: sealing between the anchor and formwork panel, and sealing between the tie rod and anchor housing. This single element replaces what would traditionally require multiple separate sealing components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single sealing element is designed with multi-functionality to perform multiple sealing tasks. It seals the interface between the anchor body and formwork panel while also sealing the interface between the tie rod and anchor housing, making one component serve multiple sealing purposes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

This design effectively prevents concrete leakage by establishing both seals with a single accessible sealing element, reducing maintenance complexity and ensuring quick replacement, thus enhancing the durability and efficiency of the sealing process.

Implementation Method 1

The sealing element is a rubber gasket arranged at the end of the tubular extension of the anchor

AI summary

Anchor for a vertical formwork having two formwork panels facing one another. The anchor (3) is suitable for being fixed to one of the formwork panels, the anchor (3) comprising a housing (34) for receiving a part of a tie rod fixing the two formwork panels, and sealing means configured for sealing the anchor (3) with respect to the formwork panel in which it is fixed and with respect to the tie rod housed in the housing (34) of the anchor (3). The sealing means comprise a sealing element (33) which is arranged at one end of the anchor (3) and configured for sealing, when the anchor (3) is fixed to the respective formwork panel, both the anchor (3) with respect to the formwork panel in which it is fixed and the anchor (3) with respect to the tie rod housed in the housing (34) of the anchor (3).
