JOINT STRUCTURE AND ITS CONSTRUCTION METHOD

PROBLEM TO BE SOLVED: To provide a joint structure and its construction method, capable of dispensing with secondary water cut-off by a moisture permeable waterproof sheet, while sufficiently coping with a request for reducing weight of an outer wall face material. SOLUTION: This joint structure K in clearance between a lower side outer wall face material 1 and an upper side outer wall face material 2, has a primary water cut-off member 10 and a secondary water cut-off member 20. The primary water cut-off member 10 has an installation part 11 installed on the upper side outer wall face material lower end 2a and a water cut-off body 12 having a water cut-off piece 14 for cutting off water by abutting on the lower side outer wall face material upper end 1a. The secondary water cut-off member 20 has an installation part 21 installed between the lower side outer wall face material 1 and a lower side panel frame 4, a support piece 22 placed on the lower side outer wall face material upper end 1a, and a water cut-off body 24 having a water cut-off piece 26 for cutting off water by abutting on an upper side outer wall face material back face 2b.
