Overlapping Formwork Table Beams for Low-Height Slab Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formwork systems face challenges in limited space applications, such as balcony slabs, due to the need for complex and high structures with multiple layers of beams, which are cumbersome to set up and inefficiently utilize available space.
Innovation Solution
The formwork table element features overlapping longitudinal and cross beams, allowing formwork props to be mounted on either beam type, with connecting elements ensuring variability and precise static adjustment, reducing construction height and simplifying transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If longitudinal beams and cross beams are arranged in two separate layers (cross beams on top of longitudinal beams), then the supporting structure is stable and load-bearing, but the construction height increases and the structure becomes complex for limited space applications
Solution Approach 1:
The patent transitions from a vertical stacking arrangement (two separate layers) to a horizontal overlapping arrangement where longitudinal beams and cross beams share the same level. This dimensional change allows the beams to be positioned side-by-side rather than one above the other, reducing the overall height of the supporting structure while maintaining stability through the overlapping configuration.
Solution Approach 2:
The patent merges the longitudinal beam layer and cross beam layer into a single overlapping level. Instead of having cross beams sit on top of longitudinal beams in a separate layer, both beam types are combined at the same vertical position, creating a unified supporting structure that reduces construction height while preserving load-bearing capacity through the interconnected overlapping beams.
2Device complexity
If longitudinal beams are positioned close to the longitudinal edges of the formwork panel, then the structure is simplified, but formwork props cannot be mounted in limited spaces such as balcony slabs
Solution Approach 1:
The patent makes the supporting structure universal by providing multiple mounting locations (both longitudinal beams and cross beams have connecting elements) that can accommodate formwork props in various positions. This multi-functional design allows the same beam structure to serve both as a simplified support system and as a versatile mounting platform for formwork props in different applications, including limited spaces like balcony slabs.
Solution Approach 2:
The patent segments the beam structure into multiple components (longitudinal beams and cross beams) with distributed connecting elements. Instead of having a single row of mounting points, the connecting elements are segmented across multiple beam types positioned at different locations, providing distributed mounting options that enable formwork prop installation in limited spaces while maintaining overall structural simplicity.
3Adaptability or versatility
If intermediate beams are added under longitudinal beams to enable prop mounting in limited spaces, then prop mounting flexibility improves, but the supporting structure becomes complex with three layers and increases construction height
Solution Approach 1:
The patent eliminates the need for intermediate beams by making the existing longitudinal and cross beams universal mounting structures. Both beam types are equipped with connecting elements that can accommodate formwork props, providing multiple mounting locations without requiring additional intermediate beam layers. This multi-functional design achieves prop mounting flexibility while avoiding the complexity of three-layer structures.
4Device complexity
If cross beams are positioned close to the longitudinal edges of the formwork panel, then the structure is simplified, but formwork props cannot be mounted on cross beams in limited space applications
Solution Approach 1:
The patent makes both longitudinal beams and cross beams universal mounting structures by providing connecting elements on both beam types. This ensures that either beam can be used to mount formwork props, providing redundant mounting options and maximum versatility. The cross beams, positioned close to longitudinal edges, now also serve as functional mounting points, eliminating the limitation of being able to mount props only on longitudinal beams.
