WATERPROOF STRUCTURE IN EXTERIOR WALL JOINT, AND CONSTRUCTION METHOD OF WATERPROOF MEMBER
To provide a waterproof structure in an exterior wall joint and a construction method of a waterproof member capable of improving water cut-off property of a waterproof member for secondary water cut-off of an exterior wall joint, under consideration of the above facts.SOLUTION: A sheet-shaped waterproof sheet 66 is disposed between an exterior wall panel 38 and a frame 50 supporting the exterior wall panel 38 at an outdoor side of an exterior wall joint 44 for secondary water cut-off of the exterior wall joint 44. Also, a plate-shaped waterproof member 68 for a screw head is disposed inside the exterior wall joint 44 and at an outdoor side of a screw head 62A of a tapping screw 62 penetrating the waterproof sheet 66. Here, in a state after the waterproof member 68 for a screw head is installed, a recessed portion 76 is formed in a center. The screw head 62A is covered with an elastic member 72 disposed inside the recessed portion 76.SELECTED DRAWING: Figure 1
【課題】本発明は上記事実を考慮し、外壁目地を二次止水する防水部材の止水性能を向上させることができる外壁目地の防水構造と、防水部材の施工方法を得る。【解決手段】外壁目地４４屋外側では、外壁パネル３８と外壁パネル３８を支持するフレーム５０との間にシート状の防水シート６６が配置され、外壁目地４４を二次止水している。また、外壁目地４４の内側で防水シート６６を貫通するタッピングビス６２のビス頭６２Ａの屋外側には板状のビス頭防水部材６８が配置されている。ここで、ビス頭防水部材６８を組み付けた後の状態では、中央に凹部７６が形成され、この凹部７６の内側に配置された弾性部材７２によってビス頭６２Ａが被覆されている。【選択図】図１
