Zusammenfassung:	PROBLEM TO BE SOLVED: To enhance the joining performance of an upper layer concrete with a lower layer concrete by using a splicing sheet having surface unevenness. SOLUTION: A splicing sheet is equipped with surface unevenness, and with the projections facing down, the sheet is laid on the bottom suffice of the camber of an exterior wall skeleton to be constructed, and steel bars for connection 12 are inserted perpendicularly to the flat surface of the sheet and secured, and upper layer concrete 20 is placed. The steel bars 12 protruding downward from the rcess in the splicing surface 14 of a capital are joined with vertical rods 15 for columanr skeleton of the lower layer by a gas pressure contact joint, etc., and a concrete form 18 is installed around the structural steel bars which were arranged, and lower layer concrete 19 for the exterior wall skeleton is placed.
