Collar Assembly for Securing Tube to Brickwork Corner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing a profile to a brickwork corner require welded plates or a variety of fixing rods, which are cumbersome and increase the range of components a bricklayer needs to carry.
Innovation Solution
A method and apparatus that utilize a tube of uniform cross section secured to a brickwork corner using collars with reference surfaces and adjustable abutments, along with a tensioning arrangement to apply force and ensure proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a Blake's profile with welded plates is used to secure the profile to the brickwork corner, then the profile can be securely positioned and aligned, but the device complexity increases due to the need for welded plates and multiple fixing rods
Solution Approach 1:
The profile is divided into two separate functional components: a simple tubular profile body and a detachable collar assembly. The collar contains the reference surfaces and adjustable abutments, allowing the profile to be secured to the brickwork corner without welding plates to the tube itself. This segmentation reduces the complexity of the profile structure while maintaining secure positioning.
Solution Approach 2:
The collar acts as an intermediary component between the simple tubular profile and the brickwork corner. It provides the reference surfaces and adjustable abutments needed for secure positioning and alignment, eliminating the need for welded plates on the profile tube while achieving the same functional outcome.
2Reliability
If a variety of fixing rods with different lengths are used to accommodate varying distances from the profile to different perpends, then the profile can be securely anchored, but the quantity of components increases
Solution Approach 1:
The collar incorporates adjustable abutments that can be positioned at different locations to accommodate varying distances from the profile to the brickwork perpends. This adjustability eliminates the need for multiple fixed-length fixing rods, as a single collar design can adapt to different installation scenarios through dynamic adjustment of the abutment positions.
Solution Approach 2:
The collar is designed as a universal component that can accommodate a range of perpend distances through its adjustable abutments. Instead of requiring different fixing rods for different distances, the same collar design can be used in various configurations to secure the profile at different positions, reducing the total number of component variants needed.
3Reliability
If welded plates with fixing rods are used to secure the profile, then the profile can be firmly attached to the brickwork, but the weight of the profile increases
Solution Approach 1:
The heavy welded plate structure is segmented and replaced by a separate collar assembly that can be removed and reused. The profile tube itself remains lightweight and simple, while the collar provides the necessary attachment functionality without permanently increasing the profile's base weight.
Solution Approach 2:
The collar serves as a reusable component that can be removed from one profile and transferred to another, rather than being permanently welded to each profile tube. This allows the lightweight profile to be used repeatedly, with the collar being recovered and reused across multiple installations, effectively reducing the overall material consumption and weight.

AI summary
An apparatus is disclosed for securing a tube of uniform cross section to a brickwork corner to serve as a profile. The apparatus comprises at least one collar for sliding onto the tube to define fixed reference surfaces to contact the two faces of the corner and to define adjustable abutments for contacting the two faces of the corner at a distance from the reference surfaces to permit adjustment of the attitude of the tube in two orthogonal planes, and a tensioning arrangement for applying a force directly or indirectly to the tube to urge the reference surfaces and the adjustable abutments into contact with the two faces of the corner.
