Climbing Bracket Hook Locking in Formwork Recesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing climbing brackets for high walls are prone to unintentional dislodgment due to inadequate securing against upward displacement, and existing solutions either compromise stability or require additional supports, interfering with formwork placement.
Innovation Solution
A combination of a climbing bracket and formwork part where the hook is secured within the formwork part using various mechanisms, including projections, locking levers, and sliding rails, to prevent upward disengagement, ensuring stability without interfering with formwork placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hook is inserted into the wall recess to secure the climbing bracket, then the bracket can be attached to the wall, but the bracket remains vulnerable to upward dislodgment due to gaps in the recess
Solution Approach 1:
The hook is nested within the formwork part, with the formwork part's recess receiving and containing the hook. This nesting arrangement ensures that the hook is securely held in place by the formwork part, preventing upward dislodgment while maintaining a compact integration of components.
Solution Approach 2:
The formwork part acts as an intermediary element between the wall recess and the climbing bracket hook. It provides a structured receiving space that mediates the connection, ensuring stable attachment while allowing the bracket to be securely fastened without direct exposure to wall recess gaps.
2Stability of the object's composition
If a wedge is inserted into the free space above the hook to prevent dislodgment, then upward displacement is restrained, but the wedge interferes with formwork placement and requires additional supports
Solution Approach 1:
The securing function is merged into the formwork part itself through the integrated recess design. The formwork part's recess directly receives and secures the hook, eliminating the need for separate wedges or additional support elements. This consolidation reduces device complexity while maintaining stability.
Solution Approach 2:
The formwork part serves multiple functions: it provides the formwork structure for concrete pouring, creates the receiving recess for the hook, and acts as the securing mechanism itself. This multi-functionality eliminates the need for additional dedicated components like wedges or supports, simplifying the overall system.
3Ease of operation
If the hook is made L-shaped for insertion into the wall recess, then the bracket can be positioned in the recess, but a gap remains above the hook allowing unintentional dislodgment
Solution Approach 1:
The L-shaped hook is nested within the formwork part's recess, with the recess contours matching the hook geometry. This nested arrangement ensures that the hook is fully contained within the recess, eliminating gaps and preventing dislodgment while maintaining ease of insertion.
Solution Approach 2:
The recess is designed with asymmetric contours that match the L-shaped hook geometry, creating a precise fit. The asymmetric design ensures that the hook cannot be dislodged upward while maintaining straightforward insertion, as the recess contours guide the hook into its secure position.

AI summary
The invention relates to a climbing bracket (1) with a frame (14) and a hook (2) slidably mounted in the frame (14), wherein the hook (2) can be suspended in a formwork part (3) that can be inserted into a wall recess and can be secured within the formwork part (3) against detachment from the formwork part (3). For securing, the formwork part (3) and the hook (2) each comprise at least one passive securing element, wherein a securing element of the formwork part (3) engages with a securing element of the hook (2) during a force acting on the hook (2) in a vertical or oblique upward direction such that detachment of the hook (2) from the formwork part (3) is prevented. The invention further relates to a formwork part (3) for suspending the climbing bracket (1).The formwork part (3) can be used to form a wall recess in a formwork and has an entry opening (31) to the outside, a closed back (5) and a recess in the lower part to accommodate part of the hook (2).
