Composite structure

摘要

An object of the present invention is to obtain economically a corrosion-resistant, abrasion-resistant or heat-resistant composite structure having a high strength by joining together two members so that the two members may not separate from each other. A composite structure is formed by combining and joining together first and second members. The first member has a protruding part expanding toward its extremity and the second member has a concave part defining a space of a shape corresponding to that of the protruding part of the first member and capable of forming a predetermined clearance between the protruding part of the first member and a surface of the concave part of the second member when the first and the second member are combined. Separation of the first and the second member from each other is prevented by inserting wedges in the clearance. Vacant portions of the clearance remaining after the wedges have been inserted in the clearance may be filled up with a filler.
