<p><P>PROBLEM TO BE SOLVED: To provide a sheath pipe for post attachment which has a simple structure and which is excellent in workability. <P>SOLUTION: The sheath pipe for post attachment is provided with a pipe body 2 which is buried in a concrete skeleton, and a mounting hole used for attaching the post to the concrete skeleton is formed in the sheath pipe for post attachment which is provided with the pipe body 2, an undersurface part 3, and a flange 3A. The pipe body 2 made of an aluminum extrusion molding material has a screw hole 4, and the undersurface part 3 covering the bottom of the pipe body 2 is fixed by a screw 10 which is screwed to the screw hole 4. Then the flange 3A is provided in the circumference of the undersurface part 3, and is positioned on the more outward side than the outer surface of the pipe body 2. The use of the aluminum extrusion molding material having the screw hole 4 eliminates the need for separately providing a screw receptacle or the like to the pipe body 2, and enables the undersurface part 3 to be fixed by the screw 10. Furthermore, since the circumference of the undersurface part 3 becomes the flange 3A, there is no need for separate processing of the brim part, and the pipe body 2 having the bottom which is provided with the flange 3A can be manufactured at low cost. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
