Adjustable Compensating Beam for Irregular Formwork Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formwork systems struggle to efficiently and reliably position and fix formwork elements in edge or corner areas with irregular dimensions, often requiring time-consuming custom supports that may not meet static requirements, risking formwork collapse.
Innovation Solution
A compensating support system comprising an outer support with a recess for an inner support, allowing adjustable length and secure fixation through a fixing element, with multiple support interfaces for load distribution and connection to other supports, enabling flexible adaptation to various dimensions and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom-made beams are fabricated for edge or corner areas, then the formwork can be positioned and secured, but the process is time-consuming and may not meet structural requirements
Solution Approach 1:
The beam system allows dynamic adjustment of length by moving the inner beam along the outer beam's longitudinal recess and using adjustable fixing elements, enabling the same standardized beam to adapt to various irregular dimensions without requiring custom fabrication for each application
Solution Approach 2:
The standardized beam system with adjustable inner and outer beams can serve multiple functions and adapt to various edge and corner configurations, replacing the need for multiple custom-made beams for different dimensional requirements
2Productivity
If custom-made beams are fabricated under time pressure, then the formwork can be positioned, but the beams may not meet structural requirements, creating collapse risk
Solution Approach 1:
The system allows changing the effective length parameter of the beam by adjusting the inner beam position relative to the outer beam, enabling the beam to be optimized for specific load requirements while maintaining structural integrity through standardized, quality-controlled components
3Ease of manufacture
If standard components are used for edge areas, then fabrication is simplified, but the beam length cannot be adjusted to match different dimensions
Solution Approach 1:
The beam system transforms static standard components into a dynamic adjustable structure where the inner beam can be positioned at different locations along the outer beam, allowing the effective length to be changed while using the same standardized parts

AI summary
The invention relates to a compensating beam for receiving formwork elements, in particular formwork panels, comprising an outer beam having an upward-facing support surface and a downward-facing base surface, and at least one inner beam having an additional upward-facing support surface and a downward-facing base surface. The compensating beam further comprises at least one fixing element. The outer beam has a longitudinally extending recess for receiving the inner beam, and the inner beam is slidably mounted in the recess of the outer beam. The fixing element is designed to fix the position of the inner beam relative to the outer beam.The invention further relates to a ceiling formwork system comprising at least one compensating beam and at least two supports which are arranged substantially perpendicular to the compensating beam.
