ABSTRACT:
A method of mounting an annular element on a tube which involves surrounding said tube by a tubular sleeve of aluminum or an alloy thereof, which is sufficiently thin to be plastically deformable and has a similar cross-section, with suitable clearance, with one of the sleeve ends having an outside bevel; surrounding said tube, on the side of the sleeve bevel, with an annular element to be fastened, wherein the annular element has at least one opening whose crosswise dimensions are greater than those of the tube, but whose radial clearance with said tube is less than the thickness of the sleeve, and which has, on the sleeve side, an inside bevel whose maximum crosswise dimensions are greater than the crosswise dimensions of the end of the element and the sleeve toward one another, by a suitable means, and introducing the sleeve, by force, between the annular element and the tube by plastically deforming the sleeve and tube, thereby mounting the annular element.
The present method is used advantageously, for example, for frameworks, bridges, scaffolding and offshore drilling platforms.
