Document Type and Number:
Japanese Patent JP3491318
Kind Code:
B2
Abstract:
PURPOSE: To obtain a sleeve which possesses the piping supporting function, by installing a plurality of piping supporting fittings which project towards piping from the inner wall surface of the sleeve and are fixedly supported on the inner wall surface of the sleeve, in the directions angularly different from each other.
CONSTITUTION: A piping sleeve 10 consists of a circular pipe 50 and a piping supporting fitting 30, and four piping supporting fittings 30 are welded in the radial direction on the inner surface of the circular pipe 50 and approach a piping 20 from directions angularly different from each other. The top end on the piping 20 side of each piping supporting fitting 30 surrounds the space through which the pipe 20 penetrates at the center of the circular pipe 50. Accordingly, the piping 20 passes through the center position of the circular pipe 50, and the displacement of the pipe is restrained, without giving an adverse influence to the pipe, and the position of the piping 20 can be set sure. Further, a hole finishing block is inserted in accordance with the cavity between the sleeve and the pipe supporting fitting, and the rest gap may be charged with motar.
