JOINT MEMBER AND STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a structure having voids therein in a short period of time. SOLUTION: The structure 6 is constituted of a plurality of main bodies 7 each having a board-like substrate 9 and projections 21 projecting from one side 10 of the substrate. The structure 5 is constructed by interposing a second joint member 48 between both connecting portions 15 of the respective main bodies 7 to connect the same together, placing the main bodies 7 so as to face both front ends 27 of the projections to each other, and interposing a first joint member 33 between both the front ends 27 of the projections. The first joint member 33 has a peripheral edge 39 having almost the same size as that of a peripheral edge 13 of the substrate formed like a board.
