Formwork Bracket for Metal Waterstop Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formwork elements fail to provide a simple and secure method for holding metal waterstops, as they either damage the surface or require cumbersome welding, especially when using joint barriers made of coated sheet metal.
Innovation Solution
A formwork element with a non-positive clamping fixation device, featuring omega-shaped brackets and a connecting strut that allows for elastic deflection to securely hold metal waterstops without damaging them, and includes a depth stop for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic edge regions clamp the joint barrier linearly, then the joint barrier is held in position, but the sharp edges damage the surface of metal water stops
Solution Approach 1:
The edge regions are designed with a curved clamping surface instead of sharp linear edges. This curved surface gradually compresses the joint barrier, avoiding concentration of stress at sharp edges and preventing damage to the metal water stop surface while maintaining secure positioning
2Reliability
If welding is used to attach metal water stops, then secure attachment is achieved, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces the welding process (thermal/chemical joining) with a mechanical clamping system. The elastic edge regions are compressed to clamp the joint barrier between them, providing secure attachment through mechanical force alone, which is much faster and simpler to install than welding
3Reliability
If tie wire clamping is used for elastic joint tapes, then the joint tape is secured, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent combines the formwork wall structure with the clamping function by integrating elastic edge regions directly into the formwork walls. This eliminates the need for separate tie wire clamping operations, as the formwork walls themselves provide the clamping force when compressed, streamlining the installation process
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
Enables easy and secure insertion of metal waterstops, preventing tipping and surface damage, while allowing for precise positioning and stable clamping, facilitating efficient construction site operations.
Implementation Method 1
the joint barrier is resiliently clamped by the mutually facing, elastic edge regions of the formwork walls
Implementation Method 2
the formwork material itself, which is preferably designed to be elastic in the edge areas, is deflected when the joint barrier is pushed in and rests against the joint barrier with an echo due to spring properties

AI summary
The shuttering component (10) is made up of two parallel panels (2) with a gap between them, into which a joint sealing sheet (7) can be fitted. A resilient clamp (5c) holding the panels together also fixes the sheet in position.
