Formwork Guide Device with Movable Bearing Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing formwork systems face difficulties in efficiently removing spacer rods after concrete hardening due to mechanical tension, requiring excessive force and often necessitating the use of extension tools or cutting the clamping nut, which increases withdrawal time and operator fatigue.
Innovation Solution
Incorporating a guide device with displacement means, such as a pivot rod and tilting mechanism, that allows the bearing support to move away from the clamping nut, reducing mechanical tension and facilitating easy loosening and removal of the spacer rod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bearing support is fixed parallel to the front formwork face, then the spacer rod maintains shuttering faces parallel, but the clamping nut is firmly locked and difficult to loosen after concrete hardening
Solution Approach 1:
The bearing support is made movable relative to the front formwork face through displacement means (pivot rod, tilting mechanism). During concrete pouring, the bearing support remains in a fixed parallel position to maintain shuttering face parallelism. After hardening, the bearing support can be displaced to move away from the clamping nut, reducing mechanical tension and enabling easy loosening of the clamping nut without requiring extension tools or cutting.
2Device complexity
If the bearing support remains in fixed position, then the guide device structure is simple, but excessive force is required to remove the spacer rod
Solution Approach 1:
The bearing support is made movable relative to the front formwork face through displacement means (pivot rod, tilting mechanism). During concrete pouring, the bearing support remains in a fixed parallel position to maintain shuttering face parallelism. After hardening, the bearing support can be displaced to move away from the clamping nut, reducing mechanical tension and enabling easy loosening of the clamping nut without requiring extension tools or cutting.
3Stability of the object's composition
If the bearing support is fixed, then the mechanical tension remains constant, but the withdrawal time of spacer rod is increased
Solution Approach 1:
The bearing support is made movable relative to the front formwork face through displacement means (pivot rod, tilting mechanism). During concrete pouring, the bearing support remains in a fixed parallel position to maintain shuttering face parallelism. After hardening, the bearing support can be displaced to move away from the clamping nut, reducing mechanical tension and enabling easy loosening of the clamping nut without requiring extension tools or cutting.

AI summary
The panel has a flat shuttering front face (AV) in which a spacer opening (2) is formed, and a back face (AR) on which a guiding device (5) is mounted, where the device guides a spacer rod (1) through the spacer opening. The device comprises a bearing support i.e. support plate (51), adapted to be in contact with a clamping nut (3) locking a position of the rod in the spacer opening. The device comprises a displacement unit for displacing the support plate with respect to the front face of the panel. The displacement unit moves the support plate between locking and release positions. An independent claim is also included for a method for withdrawing a spacer rod mounted between two opposite form panels.
