STRUCTURE USING EXTRUDED LIGHT METALLIC SECTION AND COMPOSITE PANEL

摘要

PROBLEM TO BE SOLVED: To provide a structure composed of an extruded light metallic section and a composite panel light in weight to be combined with the aforesaid section. SOLUTION: A composite panel 37 has a plastic core 32 combined with outer sheets 33 and 34 made out of light metals at its end sides. The outer sheets 33 and 34 are partially overlapped with a light metal connecting section 36 integrally assembled with the composite panel 37, and are engaged with the section 36 so as to be relatively locked with each other. The connecting section 36 has connecting strips 38 and 40 rested over the matching connecting strips 42 and 44 of the section 35 while being in a paired shape. At least one out of the connecting strips 38 is fastened with the adjacent strip 42 by a rivet. Since the connecting strip 40 of the connecting section 36 is pressed over the adjacent connection strips 44 and 38, it is inclined by a specified angle in regard to its contact plane, and its free peripheral part is thereby welded by laser so as to be joined with the connecting strip 44.
