A method for joining together of pieces (1, 2), advantageously of board-shaped structural elements, so that plastic to be cast, extruded or injected is used as the joint material, which said plastic becomes later gelled. According to the invention, moulds (3, 4) are fitted around the pieces (1, 2) to be joined together, which moulds, together with the gap allowed to remain between the pieces (1, 2), form a unified cavity structure. When this cavity structure is filled with the plastic, e.g. with a polymer mix, a through bead structure (8) that has a rivet effect is produced at the joint between the pieces (1, 2), which said bead structure, upon hardening, interconnects the pieces (1, 2) firmly. |
