Stop Anchor Inspection Opening for Post-Concrete Type Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring systems for climbing formwork in concrete structures cannot reliably identify the type of blocking mechanism after it has been concreted, leading to uncertainty in load-bearing capacity and compatibility.
Innovation Solution
A generic anchoring element comprising a barrier and a coupling element, where the coupling element has a visual opening to reveal the marking on the threaded rod, allowing identification of the barrier type from the outside, and includes a coaxial anchor and coupling bore for easy assembly and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the anchoring element is cast into concrete, then the locking anchor remains permanently in the hardened concrete, but the stop anchor type can no longer be clearly determined
Solution Approach 1:
A viewing opening is introduced as an intermediary element that allows the marking on the threaded rod to be visible from the outside through the coupling element, enabling identification of the anchor type without compromising the permanent anchoring function
Solution Approach 2:
Markings (such as color codes, engravings, or labels) are applied to the end face of the threaded rod to indicate the anchor type, allowing visual identification through the viewing opening while the anchor remains embedded in concrete
2Strength
If the coupling element is made entirely of metal, then the anchoring element has sufficient strength, but the coupling element cannot be easily removed from hardened concrete
Solution Approach 1:
The coupling element is designed with a conical shape that allows it to be easily inserted into the concrete but resist removal, providing dynamic behavior that facilitates installation while maintaining permanent anchoring
Solution Approach 2:
The anchoring system is divided into two separate components: the locking anchor (which remains in concrete) and the coupling element (which can be removed and reused), allowing the coupling element to be retrieved after the locking anchor has fulfilled its anchoring function
3Adaptability or versatility
If different types of stop anchors are used, then the load-bearing capacity can be adapted to different climbing formwork systems, but the stop anchor type cannot be identified after concreting
Solution Approach 1:
Different markings (colors, engravings, or labels) are applied to the end face of the threaded rod to indicate different anchor types and their corresponding load-bearing capacities, enabling visual identification through the viewing opening
Solution Approach 2:
The viewing opening serves as an intermediary that transmits information about the anchor type from the embedded threaded rod to the outside, allowing identification without compromising the permanent anchoring function

AI summary
The invention relates to an anchoring element for attaching a climbing formwork to a concrete body, comprising a locking anchor and a coupling element, wherein the locking anchor has a head and a threaded rod with an external thread, wherein the coupling element is an elongated cylindrical body with a base, a sleeve, and a front, and wherein the coupling element has an anchor bore extending axially inward from the base, which has an internal thread that meshes with the external thread of the threaded rod. According to the invention, the end face of the threaded rod has a marking, and an inspection opening is provided at the inner end of the anchor bore so that the end face of the threaded rod received in the anchor bore is visible from the outside.
