Angled Ceiling Formwork Frame for Safe Panel Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling of lost shuttering panels in existing ceiling formwork systems poses safety risks and inefficiencies due to the need for workers to navigate horizontal formwork beams to place panels, which can lead to occupational hazards and damage.
Innovation Solution
A method involving a ceiling formwork frame that is initially positioned at an angle, allowing safe attachment of lost ceiling panels from the floor, then pivoted upwards for secure support, reducing the need for workers to access the panels from above and minimizing protrusions, thus enhancing safety and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lost shuttering panels are placed on horizontal formwork beams from above, then the ceiling element can be produced, but workers face occupational hazards and the panels may protrude beyond edges creating safety risks
Solution Approach 1:
The patent inverts the conventional approach by having workers place lost shuttering panels on the formwork frame from the floor level rather than from above. The formwork frame is positioned at an angle where the second end region is accessible from the floor, allowing safe panel placement without workers needing to navigate horizontal beams or access protruding panel edges from above.
Solution Approach 2:
The patent changes the spatial dimension of panel placement by utilizing the inclined position of the formwork frame. Instead of placing panels horizontally from above, the inclined configuration allows vertical access from the floor, transforming a two-dimensional horizontal placement problem into a three-dimensional solution that eliminates safety hazards.
2Ease of manufacture
If workers access horizontal formwork beams to place panels, then panels can be installed, but the complexity and risk of worker navigation increases
Solution Approach 1:
The patent employs a dynamic formwork frame that can be positioned at an angle during construction and then pivoted to a horizontal use position. This dynamic configuration allows the frame to be accessible from the floor during panel installation, simplifying the manufacturing process, while later transforming into a stable horizontal structure for its intended use.
Solution Approach 2:
The patent applies preliminary action by positioning the formwork frame at an inclined angle before panel installation. This preliminary inclined position enables workers to safely access and place panels from the floor level, avoiding the need to navigate complex horizontal beam structures during the installation phase.
3Manufacturing precision
If panels are placed on protruding formwork structures, then ceiling elements can be formed, but panel damage and safety hazards increase
Solution Approach 1:
The patent inverts the placement approach by accessing the formwork frame from below at an angle rather than from above. This eliminates the creation of protruding panel edges that would otherwise pose safety hazards and potential damage risks, while still achieving the required manufacturing precision for ceiling element quality.
