Formwork Support System with Transverse Beam Catch Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formwork support systems face challenges in safety and stability during installation and stripping, particularly due to tilting issues with longitudinal beams, which can lead to accidents and complications during concrete pouring and hardening processes.
Innovation Solution
The introduction of a transverse beam design that connects easily to longitudinal beams with recesses and catch elements, preventing tilting and allowing for secure attachment and removal, along with a method for installing the system that includes interim mounting positions for stable assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If longitudinal beams are connected to head members without recesses, then the structure is simpler, but tilting occurs during assembly and stripping leading to safety issues
Solution Approach 1:
The recess in the head member receives and nests the longitudinal beam, creating a nested configuration where the beam is partially inserted into the head member structure. This nesting prevents tilting by providing a recessed seating area that mechanically constrains the beam during assembly and stripping operations.
2Reliability
If beams are securely attached to prevent tilting, then safety improves, but ease of operation during installation and removal decreases
Solution Approach 1:
The connection system transitions from a static rigid connection to a dynamic sequence of operations. The recess allows the beam to be temporarily positioned and secured, then easily removed by reversing the insertion motion. This dynamic approach enables both secure attachment during use and easy removal when needed.
Solution Approach 2:
The recess is pre-formed in the head member to guide and receive the longitudinal beam during assembly. This preliminary structural preparation ensures that when the beam is inserted, it automatically assumes the correct position and orientation, facilitating both secure attachment and easy removal without requiring complex fastening mechanisms.
3Productivity
If longitudinal beams are arranged on top of head members without recesses, then assembly is faster, but tilting prevents safe concrete pouring
Solution Approach 1:
The longitudinal beam is nested into the recess of the head member, creating a mechanically interlocked configuration. This nesting prevents tilting during concrete pouring by providing a recessed seating area that constrains the beam, while the overall assembly process remains efficient through the simple insert-secure-remove operation sequence.

AI summary
A formwork support system comprising: - four support props, each having a leg and a head member mounted on an upper end of the leg, each head member having a support plate with an upper side for supporting a formwork thereon, - two longitudinal beams with ends attached to the head members of the support props, respectively,and - a transverse beam extending transversely to the longitudinal beams, wherein the transverse beam has two catch elements at opposite end regions of the transverse beam, the catch elements engaging slots of the longitudinal beams, the catch elements being spaced apart in a horizontal direction perpendicular to a longitudinal direction of the transverse beam.
