Adjustable Adhesive Bolt Anchoring for Columns and Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting devices for anchoring columns or walls to substrates lack adjustability and comfort during assembly, often requiring manual skill and resulting in limited positioning options without compromising structural integrity.
Innovation Solution
A connecting device featuring an adhesive receiving body with a displaceable cover surface and an open gap, allowing for precise introduction and distribution of adhesive between the bolt and recess, enabling large adjustment ranges before adhesive hardening, and incorporating a support structure for adjustable anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is applied directly to the bore wall before inserting the bolt-like part, then the bond strength is improved, but it is difficult to apply the correct amount of adhesive and control adhesive oozing
Solution Approach 1:
The patent introduces an intermediary adhesive application device that delivers adhesive precisely to the bore wall. This device acts as a mediator between the adhesive source and the bonding surface, enabling controlled adhesive distribution without direct manual application, thus achieving both strong bonds and ease of manufacture.
Solution Approach 2:
The adhesive is applied to the bore wall before the bolt-like part is inserted, preparing the bonding surface in advance. This preliminary action ensures that when the bolt is inserted, immediate bonding occurs, maximizing bond strength while allowing controlled adhesive placement.
2Adaptability or versatility
If the recess diameter is made larger than the bolt diameter to allow adjustment, then the adjustment range is improved, but adhesive oozing increases and bond strength decreases
Solution Approach 1:
The intermediary adhesive application device precisely controls adhesive placement within the recess, ensuring adequate bonding even when the recess diameter is larger than the bolt diameter. This precision prevents adhesive oozing while maintaining bond strength, enabling both adjustment range and structural integrity.
3Strength
If the pin is drilled through the column to prevent upward movement, then the anti-pullout strength is improved, but the ease of assembly deteriorates due to skill requirements and visual disadvantages
Solution Approach 1:
The patent removes the pin drilling operation from the assembly process. Instead of requiring a pin to be drilled through the column, the design extracts this complex step and replaces it with a simpler adhesive-bonded connection that achieves equivalent or superior anti-pullout strength without the visual and assembly disadvantages.

AI summary
The invention relates to a connecting device (4, 13) for the rigid anchoring of a part (3) to be anchored, such as a column or a wall, on a substrate (1), wherein a bolt (5, 14) projects from below into a downwardly open recess (9) of the part (3) to be anchored and is bonded to the boundary surfaces of the recess (9). The connecting device (4, 13) has an adhesive receiving body (6, 15) which encloses a cavity (8, 26) suitable for receiving adhesive, which is bounded upwards by a cover surface (11, 21), wherein the cover surface (11, 21) is penetrated by the bolt (5, 14), wherein an open gap (12, 24) exists between the edge of the opening (10, 12) through which the bolt (5, 14) passes and the outer surface of the bolt (5, 14).
