Wall penetrating member, the wall through the structure of the piping, and through pipe method of fixing to the wall

摘要

PROBLEM TO BE SOLVED: To provide a wall part penetrating member, a wall part penetration structure of piping, and a method for fixing penetrating piping to a wall part exerting a sure water stopping function, easy in installation, and with a high degree of freedom of installation even with a simple structure.;SOLUTION: In attaching the wall part penetrating member 2 to the wall part 3, when a screw 7 is rotated from an outdoor plate 15 side, a restricting part 17 can rotate with the screw 7 until contacting a rotation restricting member 5, and when the restricting part 17 contacts the rotation restricting member 5, the restricting part 17 can move in the axial direction of the screw 7 accompanying rotation of the screw 7. Accordingly, by tightening the screw 7 from the surface on the outdoor plate 15 side of the wall part penetrating member 2, the restricting part 17 arranged on the backside of the surface of the outdoor plate 15 from which the screw 7 was rotated and the outdoor plate 15 can embrace the wall part 3.;COPYRIGHT: (C)2012,JPO&INPIT
