DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a walking guide marker A according to a first embodiment of the present invention is a convex disc having a through hole 2a which is arranged on a road surface 1 and penetrates a central portion. The body 2, a hollow rivet 3 having a head 3 a formed by enlarging the periphery of one end of a cylindrical body and a shaft 3 b at the other end, and one end 4 b of a pull rod 4 a that can be inserted through the hollow rivet 3. It has a wedge 4 with a draw rod having an enlarged diameter, and a head plug 5 for closing the through hole 2a of the convex body 2 from the surface side.

The road surface 1 includes entrances and corridors of buildings,
Examples include indoor and outdoor sidewalks, walkways in stores, and floors in waiting rooms of hospitals. These are generally based on concrete, but may be made of wood, stone, asphalt, or the like. The convex disk body 2 is a disk having a concave portion 6 which can be used as a glue reservoir inside the peripheral edge of the back surface by raising the front surface and having a step or tapered surface 2b for reducing the inner circumference of the through hole 2a to the rear surface side. It was done.

The hollow rivet 3 is preferably made of a metal that can be easily plastically deformed, such as aluminum, but the diameter and overall length are arbitrary. Wedge 4 with drawbar
Is the outer diameter of one end 4b of a pull rod 4a made of a metal wire relatively harder than the hollow rivet 3.
The diameter is expanded so as to be larger than the inner diameter of. The head plug 5 is a small disk whose outer diameter is slightly smaller than the through-hole 2a of the convex body 2 and has a surface so that an integrated appearance with the convex body 2 can be obtained with the through-hole 2a closed. Preferably project upward with substantially the same curvature as the convex body 2.

To fix the convex body 2 to the road surface 1, first, a pilot hole 7 deeper than the entire length of the hollow rivet 3 is dug down at an appropriate position on the road surface 1 using an electric drill or the like. Then, the pull bar 4a of the pull wedge 4 is inserted into the shaft portion 3b of the hollow rivet 3 from the back side, and the hollow rivet 3 is inserted into the convex body 2.
The head 3a of the hollow rivet 3 is locked to the tapered surface 2b and the shaft portion 3b is projected toward the back side of the convex body 2 by inserting the head portion 3a of the hollow rivet 3 from the front surface side of the through hole 2a. Further, the convex disc body 2 is placed on the road surface 1 such that the through hole 2 a is located directly above the pilot hole 7, and together with the shaft portion 3 b of the hollow rivet 3, one end of a pull rod 4 a of a wedge 4 with a pull rod. When the portion 4b is immersed in the pilot hole 7 through the through hole 2a, the other end 4c of the pull rod 4a is
Is projected to the surface side of.

Subsequently, as schematically shown in FIG. 2, a guide sleeve 8 for inserting the pull rod 4a of the wedge 4 with a pull rod, and the other end 4 of the pull rod 4a projecting from the rear end of the guide sleeve 8 are provided.
c, and when the head 3a of the hollow rivet 3 is pressed by the distal end surface 8a of the guide sleeve 8, the holding pair 9 retreats in the direction of arrow a away from the head 3a. Using the special tool 10 configured as described above, the pulling rod 4a of the wedge 4 with the pulling rod is forcibly pulled out to the front side of the convex body 2 while pressing the head 3a of the hollow rivet 3 against the back side.

As a result, the one end 4b of the pull rod 4a is pressed into the shaft 3b of the hollow rivet 3 so that the shaft 3b of the hollow rivet 3 is pushed and expanded. Since such expansion of the shaft portion 3b is a plastic deformation, the stress generated in the hollow rivet 3 becomes a resistance of the operation of pulling out the pull bar 4a to the surface side, and the wedge 4 with the pull bar is formed by the one end 4b of the pull bar 4a. In the process of press-fitting into the portion 3b, a tensile load is continuously applied.

Further, when the pull rod 4a of the wedge 4 with the pull rod is pulled out to the surface side, as shown in FIG. 3, the shaft portion 3b of the hollow rivet 3 is pressed against the inner peripheral surface of the pilot hole 7, and the hollow rivet 3 is pressed. Is firmly fixed to the road surface 1 together with the convex body 2. Also, when the shaft 3b is pressed against the inner peripheral surface of the pilot hole 7, the shaft 3
Since the expansion of b is restricted, the tensile load applied to the wedge 4 with the pull rod rapidly increases, and the pull rod 4a of the wedge 4 with the pull rod and one end 4b thereof have different outer diameters. As a result, a concentrated load is applied to the vicinity of these boundaries, and the two break.
From the one end 4b.

Finally, the pull rod 4 divided from one end 4b
a is removed to the outside of the through hole 2a, and the head plug 5 is driven into the through hole 2a from the surface side of the convex body 2 so that the surface thereof is substantially flush with the surface of the convex body 2. 2a is closed, the head 3a of the hollow rivet 3 is concealed, and the through hole 2a is closed.
a and the penetration of rainwater or the like into the hollow rivet 3 can be prevented.

In the above description, the convex body 2 is fixed to the road surface 1 only by pressing the shaft portion 3b of the hollow rivet 3 against the inner peripheral surface of the pilot hole 7, but the adhesive 11 is also used. By doing so, the reliability of construction may be improved. Specifically, if the adhesive 11 is applied between the shaft portion 3b of the hollow rivet 3 and the inner peripheral surface of the pilot hole 7, the hollow rivet 3 and the pilot hole 7, which are generated when rainwater or the like enters the pilot hole 7, are formed. In addition to the above, it is possible to prevent the swinging in the pilot hole 7 of the hollow rivet 3 caused by, for example, kicking of the convex body 2 by a passerby. Furthermore,
Applying the adhesive 11 between the road surface 1 and the convex body 2 has an advantage that the convex body 2 can be directly fixed to the road surface 1. In this case, since the adhesive 11 can be filled in the recess 6, the adhesive 11 does not leak out from the periphery of the convex body 2.
