Arc-Shaped Bridging Element in Formwork Panel Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Formwork panels in construction require improved handling and stability to facilitate the production of high walls or wall elements, especially when dealing with the outward pressure of cast concrete, which current systems struggle to manage efficiently.
Innovation Solution
Incorporating an arc-shaped bridging element between transverse struts of the formwork panel frame, which serves as a handle, climbing aid, and enhances the panel's stiffness, allowing for easier transportation and positioning, and providing a larger contact region for fixing to the struts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If formwork panels are made stable and rigid to bear concrete loads, then structural strength is improved, but handling and positioning become more difficult
Solution Approach 1:
The formwork panel is divided into a frame structure with multiple longitudinal and transverse struts, creating a modular grid system. This segmentation allows the panel to maintain overall strength while enabling localized handling points and flexible assembly/disassembly operations.
Solution Approach 2:
Bridging elements are introduced as intermediary components connecting transverse struts. These bridging elements serve dual functions: they enhance the structural rigidity of the frame while simultaneously providing ergonomic handles that facilitate easier handling and positioning of the heavy formwork panel.
2Manufacturing precision
If formwork panels are made rigid to avoid deformation, then dimensional accuracy is improved, but handling becomes more difficult
Solution Approach 1:
The frame is segmented into multiple struts arranged in a grid pattern, with bridging elements connecting transverse struts. This segmentation creates a rigid triangulated structure that resists deformation while the distributed configuration provides multiple handling points for easier manipulation.
Solution Approach 2:
The bridging elements feature curved or arc-shaped designs that provide ergonomic handles for workers. These curved geometries improve grip and leverage during handling operations while the overall rigid frame structure maintains dimensional accuracy.
3Reliability
If formwork panels are designed for stability to absorb concrete pressure, then structural reliability is improved, but worker accessibility and handling are worsened
Solution Approach 1:
The formwork panel uses a segmented frame with multiple longitudinal and transverse struts connected by bridging elements. This segmentation creates a stable load-bearing structure that reliably absorbs concrete pressure while the distributed strut configuration provides multiple access points and handling locations for workers.
Solution Approach 2:
Bridging elements serve as intermediary components that connect transverse struts and provide ergonomic handles. These intermediaries improve worker accessibility and handling ease without compromising the structural reliability needed to absorb concrete pressure.
4Ease of manufacture
If formwork panels use simple strut structures, then manufacturing is easier, but handling and positioning become more difficult
Solution Approach 1:
The formwork panel employs a segmented frame structure with standardized longitudinal and transverse struts. This segmentation allows for efficient manufacturing of individual components that can be easily assembled, while the resulting grid configuration provides multiple handling points for improved operability.
Solution Approach 2:
Bridging elements are introduced as additional intermediary components that connect transverse struts. These elements are relatively simple to manufacture but significantly improve handling and positioning ease by providing ergonomic handles and structural reinforcement.

AI summary
A formwork panel, comprising a frame on the front side of which a formwork shell can be fixed. The frame has a plurality of longitudinal struts and a plurality of transverse struts running plane-parallel to one another. The longitudinal struts and the transverse struts are arranged substantially perpendicular to one another. Between at least two transverse struts running adjacent to one another, there is arranged at least one bridging element having an arc-shaped design. The bridging element has two end regions, one of the end regions being fixed in each case to one of the adjacent transverse struts.
