THROUGH-WALL CONSTRUCTION OF THROUGH-WALL PIPING, AND THROUGH-WALL PENETRATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a through-wall penetration device of through-wall piping capable of penetrating the wall of a housing with a sheath pipe, arranging along the wall without forcefully bending, and also capable of arranging piping passed through the sheath pipe without forcefully bending.;SOLUTION: The through-wall penetration device 51 is provided with a cylindrical sheath pipe guide 54, a wall presser 55, and a lock nut (fixing means) 56. The sheath pipe guide 54 is inserted into a setting hole 53 penetrating a face panel (external wall) 52 of the housing diagonally, having a flange 61 hung over one surface of the external wall 52. The sheath pipe 5 passes through the guide 54 to penetrate the external wall 52 successively. The wall presser 55 is slidably fitted into the outer periphery of a sheath pipe guide 54 part projected diagonally from the other surface of the external wall 52 to sandwich the outer wall 52 between the flange 61. The nut 56 is screwed onto the projection part of the sheath pipe guide 54, and the wall presser 55 is pressed against the outer wall 52 by the clamping force.;COPYRIGHT: (C)2006,JPO&NCIPI
