The curable material filled in the molded body in an uncured state is cured with the two fibrous rod-shaped structural materials inserted through the openings of the molded body brought into abutment with their opposing end surfaces. When the two structural materials are pulled apart from each other, the applied tensile force is initially supported by the binding force of the curable material to the side structural materials, and further As the applied tensile force increases, a crack occurs in the center of the curable material, and the curable material separates into approximately two halves, creating a wedge action on the compact tapering from the center toward the end openings. acts, and the curable material tightens the side structural material by the outer periphery, and the greater the tensile force acts, the greater the tightening force of the curable material against the structural material; This also acts on the reinforcing fibers that make up each structural material, resulting in extremely strong bonding of these structural materials.

This figure shows a state in which two fibrous rod-shaped structural materials (2), (2) are joined using a joint (1) for coarse rod-shaped structural materials, and (3) in the figure shows the center part (4). shows a cylindrical fiber-reinforced synthetic resin molded body (3) that bulges out and tapers toward openings (5) at both ends, and the molded body (3) is made of cylindrically knitted aromatic polyamide fibers coated with epoxide resin. It is formed by impregnation and curing. In the central part (4) of the molded body (3), two fibrous rod-shaped structural materials (2) are butted together at their opposing end surfaces, and the molded body (3) The interior is filled with a hardening material (6) such as high-strength mortar or epoxy resin and hardened.
