PROBLEM TO BE SOLVED: To reduce field-work manhours and make remarkable improvement in execution workability. SOLUTION: A frame 32 on the upper side of a wall panel 30 is composed of a square cylindrical hollow frame and a slit is provided on the top of the hollow frame as an opening. By inserting the leg piece 40d of a joint 40 into the slit, the joint 40 is locked so that it can not make a vertical movement with respect to the frame 32. A ceiling panel 26 is placed on the upper end surface of the wall panel 30 and an erecting piece 26a thereof is caused to be parallel to a rising piece 40a. The erecting piece 26a is inserted between the rising piece 40a and a hook piece 40b by pressing a joint material 28 in between the wall panel 30 and the ceiling panel 26 and pushing the ceiling panel 26 up. Thus the ceiling panel 26 and the wall panel 30 are solidly connected together. |
