Locking all sections

Joining framework sections to other sections can be a bit of a lottery when one considers how many different profiles and materials these sections can be made of

. Butt joins can be particularly problematic as the integrity of the joint can be compromised if it is not tight enough or if it allows too much play.
Keyways play an important role in many systems as they allow certain forms of anchors to be encased within the envelope of the profiles, securing one to the other. However, when it comes to joining smooth profiles there are no external features to rely on.
Solution: Cornwall-based Hydra Lock believes it has the answer with its Hydra Lock joining hardware. This system is extremely simple, relying on the concept of geometric locks to secure one piece to another.
The Hydra Lock comprises two locking pieces and a securing bolt: the locking pieces exhibit the same cross-sectional shape as the profile but the two faces, which butt up against each other, of the two locking pieces are inclined. When the bolt is tightened, it draws the two inclined faced towards each other and they slip slightly in opposite directions, taking them out of axial alignment and forcing them against opposite internal faces of the profile, thereby providing the locking force.
Applications: The beauty of this approach is that the locking device can be used for joining numerous profiles to other profiles which do not exhibit the same cross section – square to round, round to square, round to round, and so on. Components, which are made from aluminium or zinc die cast, are ideal for self-assembly furniture as they eliminate welded joints, fit a wide range of bore sizes to BS 6232 Pt5 (1982), are easily dismantled for repair and maintenance, and eliminate the need for a saddle for round or oval tubes.
Typical applications include tubular furniture, guard rails and barriers, tents, marquees, jigs and fixtures, racking and shelving, and numerous other frame-based constructions. MF
