Climbing Bracket Hook with Pivoting Safety Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing climbing bracket anchoring systems require manual intervention and separate safety elements, such as wedges, which are not visually recognizable and can be insecure, especially during construction processes involving concrete pouring, leading to risks of detachment and incomplete securing.
Innovation Solution
A climbing bracket system with a two-armed safety element that pivots upwards upon hook insertion, allowing a bolt to be inserted for secure attachment and visible confirmation, preventing the bracket from being pulled out, and a sliding bolt mechanism that automatically locks the safety element in place without manual effort, ensuring secure attachment and easy release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual wedge is used to secure the climbing bracket, then the bracket can be held securely, but the construction worker must manually insert and remove the wedge, increasing the risk of incomplete securing and detachment
Solution Approach 1:
The climbing bracket system automatically secures itself by utilizing the weight of the bracket and the geometry of the hook-anchoring device connection. When the bracket is lowered into position, gravity causes the hook to engage with the anchoring device, and the bracket's own weight prevents detachment, eliminating the need for manual wedge insertion or removal operations.
Solution Approach 2:
The invention removes the separate manual wedge securing element from the system. Instead of using a wedge that must be manually inserted and removed, the design integrates the securing function directly into the hook-anchoring device connection, where the bracket's weight and the geometric configuration provide automatic retention without additional components.
2Reliability
If a separate safety element like a wedge is used, then the bracket can be prevented from detaching, but the safety element is not visually recognizable and can be forgotten or incompletely installed
Solution Approach 1:
The invention merges the safety securing function with the primary hanging function of the hook. The same hook that suspends the bracket also provides the securing action through its engagement with the anchoring device. This integration ensures that the safety mechanism is always visible and apparent, as it is part of the primary structural connection rather than a separate component.
3Reliability
If the hook is manually cranked to grip the reinforcing iron, then the bracket can be secured, but the process becomes difficult and time-consuming
Solution Approach 1:
The bracket system automatically engages with the anchoring device through its own weight and the geometric configuration of the hook. When lowered into position, the hook naturally engages with the anchoring device without requiring manual cranking or additional securing operations, significantly reducing installation time while maintaining reliable securing.
4Productivity
If concrete is poured above the horizontal traverse, then the formwork can be set, but concrete can get through the opening into the formwork part and harden there, causing incomplete securing
Solution Approach 1:
The invention provides preliminary protection against concrete ingress by designing the hook and anchoring device connection to close off the opening before concrete pouring begins. The hook's engagement with the anchoring device creates a sealed connection that prevents concrete from entering the formwork part, allowing concrete pouring to proceed without risk of contamination or incomplete securing.
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
The system provides a visually recognizable and secure attachment mechanism that prevents accidental detachment, ensures correct attachment, and allows for easy release without manual effort, reducing the risk of incomplete securing and detachment during concrete pouring.
Implementation Method 1
the climbing bracket is only held by gravity
Implementation Method 2
a lever which is guided in a slot is articulated on the hook. When the hook is inserted, this lever inclines so far that the hook can be inserted into the opening of the formwork part
Implementation Method 3
the lever should tilt into a vertical position due to a frictional force

AI summary
The system for attaching a climbing bracket (1) to an anchoring device (23) embedded in a substructure comprises the climbing bracket (1) on which a hook (11) is slidably guided in the upper leg (3) and in which a safety element (19) attached to the hook (11) extends upwards or laterally from the cross-sectional area of the hook (11) after the hook (11) has been inserted through the insertion channel (26) and thereby prevents the hook (11) from being withdrawn through the insertion channel (26).
