Ceiling Formwork Quick-Release Profiles for Early Dismantling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling formwork systems require grating elements and vertical supports to remain in place for up to fourteen days during concrete hardening, limiting their use for other purposes and posing safety risks during assembly, especially when using hollow blocks or cassettes.
Innovation Solution
The ceiling formwork system allows for the insertion of quick-release profiles between grating elements, enabling safe assembly and early dismantling of grating elements and vertical supports, with the quick-release profiles providing support during the initial hardening period and being easily introduced between grating elements from above, ensuring fall protection and efficient material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If grating elements and vertical supports are left in place for the entire hardening process (up to fourteen days), then the ceiling structure is adequately supported, but the grating elements cannot be reused and material costs increase
Solution Approach 1:
The support system is segmented into two functional parts: grating elements for initial support and fall protection, and quick-release profiles for continued support during later hardening. This segmentation allows the grating elements to be dismantled early (after 1-2 days) while the quick-release profiles remain to provide ongoing support, enabling reuse of grating elements and reducing downtime loss
Solution Approach 2:
The quick-release profiles act as an intermediary element that takes over the support function from the grating elements. After the grating elements are dismantled early, the quick-release profiles serve as the intermediate support structure that maintains ceiling stability during the remaining hardening period, allowing grating elements to be reused without compromising support reliability
2Stability of the object's composition
If grating elements are assembled from the level below, then safety during assembly is compromised as workers must work on incomplete levels, but complete grating elements provide better structural integrity
Solution Approach 1:
The assembly sequence is inverted: instead of building grating elements from below and risking falls on incomplete structures, the grating elements are assembled complete from the level below first, creating a stable platform. Then the quick-release profiles are inserted from above, allowing workers to safely enter the completed level without exposure to fall risks during grating assembly
3Object-affected harmful factors
If quick-release profiles are inserted from above between grating elements, then assembly safety is improved as workers can enter completed levels, but the system complexity increases
Solution Approach 1:
The quick-release profiles serve multiple functions: they provide continued support during the later hardening period after grating element removal, enable safe worker access to completed levels, and facilitate early dismantling of grating elements for reuse. This multi-functionality justifies the added component while delivering comprehensive safety and efficiency benefits

AI summary
The invention relates to a ceiling formwork system comprising several grid elements, each of which is composed of a plurality of parallel longitudinal beams and at least one transversal beam that can be mounted or placed on vertical supports and extends perpendicular to the longitudinal beams. At least two adjacent grid elements can be mounted at a distance from each other in such a way that a profiled rapid shuttering element can be introduced from above between grid elements mounted in said fashion.
