Floor Table Mold Holder Access Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional floor tables for concrete formworks require technicians to walk on inclined, potentially slippery formwork surfaces to fasten crane harness ligaments, necessitating significant manual effort and safety concerns during the displacement process.
Innovation Solution
Designing holders on the floor table to be accessible from beneath the freshly hardened concrete floor, allowing ligaments to be fastened before horizontal displacement, enabling crane-assisted movement and reducing manual labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If technicians manually displace the floor table by pushing it out from under the hardened concrete floor, then the floor table can be positioned for crane harness attachment, but technicians must walk on inclined, potentially slippery formwork surfaces requiring special safety measures and significant manual effort
Solution Approach 1:
Instead of having technicians access the upper side of the floor table to fasten ligaments, the patent inverts the approach by providing access from the lower side. The formwork surface includes openings that allow technicians to reach holders on the lower side of the floor table from beneath the hardened concrete floor, eliminating the need to walk on inclined, slippery surfaces.
Solution Approach 2:
The patent transitions from vertical access (technicians walking on the upper surface) to horizontal access through openings in the formwork. By creating openings in the formwork surface, technicians can access holders from a different spatial dimension - from beneath the concrete floor rather than from above, thereby avoiding the hazardous inclined surface.
2Ease of operation
If technicians manually push the floor table out to expose holders, then ligaments can be fastened, but considerable manual labor is required
Solution Approach 1:
The patent applies preliminary action by providing openings in the formwork surface before the displacement process begins. These openings are pre-configured to allow access to the holders from the lower side, so that when the floor table needs to be positioned, technicians can immediately access the holders without needing to push the table far enough to expose upper-side holders.
Solution Approach 2:
The openings in the formwork serve as intermediaries, allowing technicians to reach the holders on the lower side of the floor table without needing to physically push the entire floor table structure. The openings provide a direct access path through the formwork, mediating between the technician's position and the holders.
3Adaptability or versatility
If the floor table is designed with holders on the upper side, then crane harness can be attached, but technicians must access the upper side requiring them to walk on the formwork surface
Solution Approach 1:
The patent inverts the conventional arrangement by placing holders on the lower side of the floor table instead of the upper side. This inversion allows crane harness ligaments to be attached from beneath the hardened concrete floor through openings in the formwork, eliminating the safety hazards associated with technicians walking on the formwork surface.
Solution Approach 2:
The patent changes the spatial dimension of holder placement from the upper vertical surface to the lower horizontal surface. By positioning holders on the lower side accessible through formwork openings, the design moves the attachment point to a different spatial plane, allowing safe access from beneath the concrete floor rather than from above.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates safer and more efficient displacement of floor tables by eliminating the need for technicians to access the upper side of the formwork, minimizing manual effort, and utilizing crane power for horizontal displacement.
Implementation Method 1
The floor table is disposed on roller means. The floor table without formwork is then manually displaced in a horizontal direction

AI summary
A floor table (1) of a concrete mould for producing a concrete floor (2), comprising at least one front (18, 19) and one rear holder (23) for fixing at least one front (11) and at least one rear ligament (12) of a crane harness (9), characterized in that when the floor table (1) is in a disengaged and retracted state underneath a recently hardened concrete floor (2), it is possible to have access to the holders (18, 18 23) which are used to fix the ligaments (11, 12). The inventive floor table can be drawn out from the floor and displaced with less danger to the workers and requiring less effort in comparison with conventional floor tables.
