WATERPROOF STRUCTURE OF JOINT PART OF ROOF PANEL AND WATERPROOFING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a waterproof structure which reduces works at the construction site for the joint parts of roof panels and improves the working efficiency. ;SOLUTION: One waterproof sheet 23A is placed over the other sheathing roof board 22B in the joint part 30 of roof panels. And a heat-insulative cover 41 stuck on the underface of the extended part 23A' is laid so as to stride over the adjacent roof panels 20A, 208. And the other waterproof sheet 23B is laid over one roof panel 20A and overlapped on the waterproof sheet 23A and closely stuck thereon. Since respective waterproof sheets 23A, 23B are directly and tightly stuck, an additional waterproof tape is not required and hence, the works in the construction site can be reduced and the working efficiency can be increased.;COPYRIGHT: (C)1998,JPO
