Adjustable Formwork Support Head for Early Striking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drop-head supports for floor formwork are costly and complex, leading to high material maintenance costs and the risk of undesired traces on concrete floors due to contact with multiple materials during early striking.
Innovation Solution
A support head with two adjustable support portions that allow efficient disassembly and reuse, ensuring no large support-free zones are created, reducing the need for complex drop-head supports and minimizing contact with different materials during concrete setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional drop-head supports are used for early striking, then the formwork can be removed early, but the support heads create high material maintenance costs and complex structures
Solution Approach 1:
The support head is divided into two separate support portions (first support portion and second support portion) that can be independently adjusted and positioned. This segmentation allows the formwork to be removed early while maintaining support functionality through the adjustable portions, reducing the need for complex integrated drop-head structures.
Solution Approach 2:
The support portions are designed to be movable relative to each other, with the first support portion being adjustable in position. This dynamic capability enables the support head to adapt during the construction process, allowing early removal of formwork while maintaining structural support, thereby reducing overall device complexity.
2Reliability
If drop-head supports remain standing after early striking, then the floor can be supported, but undesired traces may appear on the concrete floor surface due to contact with multiple materials
Solution Approach 1:
The invention extracts the support function from the formwork support structure itself and transfers it to separate adjustable support portions. This allows the concrete to be supported without direct contact with the formwork support materials, preventing undesired traces on the concrete surface while maintaining support stability.
Solution Approach 2:
The adjustable support portions act as intermediaries between the formwork support and the concrete floor. These portions provide the necessary support while minimizing direct material contact that would cause traces, thereby protecting the concrete surface quality while maintaining structural reliability.
3Device complexity
If support heads are reused after early striking, then material costs are reduced, but large support-free zones may be created that could damage the concrete
Solution Approach 1:
The movable first support portion can be dynamically repositioned to maintain continuous support along the floor structure. This dynamic adjustment prevents the creation of large support-free zones that would damage the concrete, while still enabling efficient reuse of the support head structure.
Solution Approach 2:
The adjustable support portions are pre-configured to be positioned at critical locations before formwork removal. This preliminary positioning ensures that support is maintained where needed to prevent concrete damage, while still allowing for the reuse and relocation of support heads to different positions.

AI summary
A support head for attachment to a formwork support for creating the formwork for a floor using a large number of floor formwork elements which each have a form surface. The support head has two support portions suitable for supporting at least one pair of adjacent floor formwork elements of the large number of floor formwork elements. The support head has an adjustment device for moving a first support portion into an arrangement in which the floor formwork element which can be mounted on the first support portion can be mounted thereon on at least one subjacent mounting point which is at a lower mounting height than a formwork mounting height. The mounting point of the second support portion remains at the formwork mounting height.
