CUT-OFF MARK HOLDER

摘要

PROBLEM TO BE SOLVED: To provide a cut-off mark holder in which screws of fastening mechanisms are provided at two positions on the center lines of all four side faces of a mark pole holding part having a square cross section, namely, totally at eight positions so as to firmly hold a base part of a cut-off mark pole in four directions on a horizontal plane and further at upper and lower sides, respectively, and a loading plate for supporting and fixing a lower part of the cut-off mark pole is disposed in distal ends of diagonal parts of a guide stationary plate for a long shaft part and a guide stationary plate for a short shaft part so as to stably load the cut-off mark pole thereon.SOLUTION: A cut-off mark holder X is raised by press-installing and engaging a guide stationary plate 2 for a long shaft part and a guide stationary plate 3 for a short shaft part which are orthogonal, into a root a1 of a cut-off mark pole (a) buried underground. In the cut-off mark holder X, fastening mechanisms 9 are provided at two upper and lower positions on the center lines of four peripheral faces of a mark pole holding part 7 having a square cross section of a rectangle of the cut-off mark holder X, namely, totally at eight positions. The fastening mechanism 9 includes: a nut part; and a screw which is threaded to the nut part, and a base part of the cut-off mark pole (a) to be inserted into the mark pole holding part 7 can be pushed in and fixed at upper and lower sides in four peripheral directions.
