Title (EN) FLEXIBLE PIPE PROTECTION STRUCTURE
(FR) STRUCTURE DE PROTECTION DE TUYAU FLEXIBLE
(JA) フレキシブル配管の保護構造
Abstract:
(EN) Provided is a flexible pipe protection structure that can easily protect even a general-purpose flexible pipe and can easily protect even a part of a pipe. The protection structure (1) according to the present invention is a structure for protecting a flexible pipe 3 in sprinkler piping (2), and comprises: a blade (4) made of metallic fibers; metal caulking covers (5) mounted inside the blade (4); and a cylindrical metal blade collar (6). The caulking covers (5) have a shape formed with halved pieces of a cylindrical member, and when fitted together, a pair of halved caulking covers (5) form a cylindrical shape. Each of the caulking covers (5) is provided with engagement protrusions (11) that protrude radially inward from the surface. Each of the caulking covers (5) is mounted to the outer circumferential surface of the flexible pipe (3), and thus the engagement protrusions (11) provided at two locations come into engagement with grooves (9) of the flexible pipe (3).
(FR) L'invention concerne une structure de protection de tuyau flexible qui peut facilement protéger même un tuyau flexible d'usage général et peut facilement protéger même une partie d'un tuyau. La structure de protection (1) selon la présente invention est une structure de protection d'un tuyau flexible (3) dans une tuyauterie d'arroseur (2) et comprend : une lame (4) constituée de fibres métalliques ; des couvercles de matage métalliques (5) montés à l'intérieur de la lame (4) ; et un collier de lame métallique cylindrique (6). Les couvercles de matage (5) ont une forme formée avec des morceaux divisés en deux d'un élément cylindrique et, lorsqu'ils sont emboîtés l'un dans l'autre, une paire de couvercles de matage (5) divisés forment une forme cylindrique. Chacun des couvercles de matage (5) est pourvu de saillies de mise en prise (11) qui font saillie radialement vers l'intérieur à partir de la surface. Chacun des couvercles de matage (5) est monté sur la surface circonférentielle externe du tuyau flexible (3), et ainsi les saillies de mise en prise (11) disposées en deux emplacements viennent en prise avec des rainures (9) du tuyau flexible (3).
(JA) 汎用のフレキシブル配管であっても容易に保護でき、配管の一部であっても容易に保護することができるフレキシブル配管の保護構造を提供する。本実施形態の保護構造(1)は、スプリンクラー用配管(2)のフレキシブル配管3を保護する構造であり、金属繊維から形成されたブレード(4)と、ブレード(4)の内部に装着されている金属製のカシメカバー(5)と、金属製の円筒状のブレードカラー(6)から構成される。カシメカバー(5)は、円筒部材を二つ割りにした形状であり、一対のカシメカバー(5)を組み合わせると筒状となる。カシメカバー(5)には、表面から径方向内側に向かって突出する係合凸部(11)が設けられる。カシメカバー(5)は、フレキシブル配管(3)の外周面に装着され、2箇所に設けられた係合凸部(11)がフレキシブル配管(3)の溝(9)と係合する。
