Pivotable Anchor Sealing Disc for Concrete
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor sealing systems require additional components, such as nuts, to ensure the sealing compound does not escape, which complicates the installation process and requires additional steps after the compound has hardened.
Innovation Solution
An anchor with a pivotable sealing element featuring an internal thread that engages with the external thread of the anchor, allowing axial movement and pivoting relative to the anchor's longitudinal axis, eliminating the need for additional components and enabling the sealing element to be pressed against the anchor base before the sealing compound hardens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a nut is used to press the sealing element against the anchor base, then the sealing compound is prevented from escaping, but the installation process becomes more complex and requires additional steps after the compound hardens
Solution Approach 1:
The patent combines the sealing element with the anchor by integrating the sealing element directly onto the anchor shaft, eliminating the need for a separate nut component. This merging of functions allows the sealing element to be pressed against the anchor base through the anchor's own structure, maintaining sealing effectiveness while simplifying the installation process and removing the need for additional fastening steps after compound hardening
2Reliability
If a nut is used to secure the sealing element, then sealing is achieved, but the fastening object cannot be attached until the nut is loosened after compound hardening
Solution Approach 1:
The patent enables the fastening object to be attached to the anchor in advance, before the sealing compound hardens, by designing the sealing element to be securely held on the anchor without requiring a nut. This preliminary action allows the fastening object to be installed immediately, saving time that would otherwise be lost waiting for the compound to harden before removing the nut
3Manufacturing precision
If the sealing element is fixed rigidly on the anchor, then alignment is precise, but the anchor cannot compensate for non-perpendicular anchoring
Solution Approach 1:
The patent makes the sealing element pivotable relative to the anchor shaft, allowing it to dynamically adjust its angular position to compensate for non-perpendicular anchoring. This dynamic capability enables the sealing element to maintain proper alignment and contact with the anchor base even when the anchor is installed at angles other than 90 degrees, combining adaptability with effective sealing
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
This design simplifies and accelerates the installation process by allowing the object to be fastened and the sealing compound to be applied in a single step, ensuring a secure seal without additional components and improving alignment with the anchor surface.
Implementation Method 1
the through hole of the sealing element has an internal thread that fits with play to the external thread of the armature. If the external thread of the armature and the internal thread of the sealing element are in engagement, the sealing element is fixed axially on the armature, with the sealing element being able to be moved axially on the armature by means of screws
Implementation Method 2
the sealing element can be pressed against the anchor base before the sealing compound hardens

AI summary
The invention relates to an anchor (1) for anchoring in an anchor base (20) made of, for example, concrete. The invention proposes to provide the anchor (1) with a perforated disc (3) as a sealing element (4), which is pivotably connected to the anchor (1, 2) by threads (6, 7) having play, so that it compensates for any inclination of the anchor (1, 2).
