Cross-Plate Formwork Head for Multi-Beam and Panel Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supporting heads for floor slabs are limited in their ability to support multiple beams, require beam interposition for panel support, and cannot facilitate frame structures with crossed beam junctions or direct panel support near walls.
Innovation Solution
A supporting head with a horizontal lower plate, parallel upper plate, and cross-arranged first and second plates with vertical protrusions that allow beam and panel support at ends and intermediate zones, enabling multiple directions and easy installation/dismantling, and includes reversible locking means for enhanced stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed supporting head supports a single beam, then the beam positioning is simple, but it cannot support multiple beams or create frame structures with crossed beam junctions
Solution Approach 1:
The supporting head is divided into multiple functional plates (first plate, second plate, third plate) that can independently support different beams. Each plate has protrusions that define resting regions for beams, allowing the head to support multiple beams in different directions simultaneously, enabling frame structures with crossed beam junctions
Solution Approach 2:
The supporting head is designed with multiple plates and protrusions that enable it to perform multiple functions: supporting single beams, supporting multiple contiguous beams, creating crossed beam junctions, and providing intermediate support regions. This multi-functional design increases adaptability without proportionally increasing complexity
2Adaptability or versatility
If fixed supporting heads are used to support panels directly without beams, then construction flexibility near walls is improved, but the head structure becomes more complex
Solution Approach 1:
The supporting head incorporates both beam-supporting features (protrusions defining resting regions) and panel-supporting features (flat surfaces and openings). The third plate with openings can directly support panels while the first and second plates support beams, allowing the same device to handle both beam and panel support functions
Solution Approach 2:
The supporting head acts as an intermediary between the prop and the formwork system. It can directly support panels in certain configurations (near walls) or support beams that in turn support panels, providing flexibility in the construction approach without requiring separate devices
3Ease of operation
If drop type supporting heads are used, then the heads can be removed after concrete casting, but they require an upright that creates gaps between contiguous panels
Solution Approach 1:
The invention extracts the upright component from the supporting head design. By eliminating the upright, the head can support beams in direct contact with each other, allowing contiguous panels to be positioned in mutual contact without gaps. The head achieves stability and functionality without the upright structure that caused the panel alignment issue
4Shape
If filling elements are used to fill spaces between panels, then panel gaps are prevented, but the construction process becomes more complex and time-consuming
Solution Approach 1:
The invention eliminates the need for filling elements by designing the supporting head to support beams in direct contact. This removes the entire filling element subsystem, including the upright, the filling elements themselves, and the associated installation and removal operations, thereby improving construction productivity
