Title
(EN) MEMBER AND METHOD FOR REINFORCING BONDED SECTION OF FLUOROCARBON RESIN PIPE
(FR) ÉLÉMENT ET PROCÉDÉ PERMETTANT DE RENFORCER UNE SECTION COLLÉE DE TUYAU EN RÉSINE FLUOROCARBONÉE
(JA) フロロカーボン系樹脂製配管の接合部の補強部材及び補強方法
Abstract
(EN)
A reinforcing member is obtained by combining a pair of identically shaped cover members (1A) and (1B) made of a fluorocarbon resin. The inside diameter of a circle formed by combining the cover members (1A) and (1B) is set so as to be equal to the outside diameter of a pipe that is to be reinforced. In the widthwise centers of the cover members (1A) and (1B), grooves are formed along the inner peripheral surface. Water-draining holes (3) are formed through the thickness direction in the peaks of the arcs of the cover members (1A, 1B), and screw grooves (3A) are formed in the water-draining holes (3) from the outside inward. This reinforcing member makes it possible to reinforce, in a simple manner, a bonded section in which a fluorocarbon resin pipe for circulating fluid and another pipe-shaped member are bonded by welding.
(FR)
Selon l'invention, on obtient un élément de renforcement en combinant une paire d'éléments de couverture de forme identique (1A) et (1B) constitués d'une résine fluorocarbonée. Le diamètre intérieur d'un cercle formé en combinant les éléments de couverture (1A) et (1B) est ajusté pour être égal au diamètre extérieur d'un tuyau à renforcer. Au centre dans le sens de la largeur des éléments de couverture (1A) et (1B), des rainures sont formées le long de la surface périphérique intérieure. Des trous de drainage d'eau (3) sont formés dans la direction de l'épaisseur dans les crêtes des arcs des éléments de couverture (1A, 1B), et des sillons de vis (3A) sont formés dans les trous de drainage d'eau (3) de l'extérieur vers l'intérieur. Cet élément de renforcement permet de renforcer, simplement, une section collée dans laquelle un tuyau en résine fluorocarbonée permettant la circulation de fluide et un autre élément en forme de tuyau sont collés par soudage.

補強部材は同一形状のフロロカーボン系樹脂製の一対のカバー部材(1A)及び(1B)を組み合わせてなる。そして、カバー部材(1A)及び(1B)を組み合わせて形成される円の内径は、補強対象となる配管の外径と同じ内径に設定されている。このカバー部材(1A)及び(1B)の幅方向中央部には溝部が内周面に沿って形成されている。また、カバー部材(1A,1B)の円弧の頂部には、厚さ方向に貫通して排水孔(3)が形成されており、この排水孔3には外側から内側に向けてネジ溝(3A)が形成されている。かかる補強部材によれば、液体流通用のフロロカーボン系樹脂製配管と他の管状部材とを溶着により接合した接合部を簡単に補強可能である。
