Abstract:

A method of forming an adhesive joint, a structural subassembly, and a joint construction. The method comprises telescopically assembling male and female tubular members having slightly different diameters to cooperatively define a narrow continuous open-end adhesive chamber between contiguous surfaces of the assembled members. Four (4) or more centering pins equally circumaxially spaced about the members are forcefully entered in the adhesive chambers to equalize spacing between the members throughout the chamber. A distributing device communicates with the adhesive chamber for the introduction of adhesive under pressure to the chamber, thus forming a secure joint.In a fabrication method for a structural subassembly at least three (3) tubular structural members are loosely assembled with three (3) joint members each having at least two cups. Centering pins are forcefully introduced between contiguous surfaces of the members and cups and a distribution device encloses the open end of the adhesive chamber. Adhesive is then introduced between the contiguous surfaces of the members to form secure joints throughout.A joint construction is produced in the practice of the method of the invention.
