There is a problem that the work efficiency becomes poor and the work time is long.

Further, in the conventional example shown in FIG. 7, since the tapping screw is fastened to the insert nut h, when the above-described method using the adhesive g is used together, the marker body a Although it does not take time to press the surface, it is necessary to turn the tapping screw by hand or rotate it with a motor while pressing it on the insert nut h using a screwdriver or the like, and it is necessary to perform the same number of times as the number of shafts d. There is a problem that efficiency is poor.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for constructing a walking guidance marker which can improve the efficiency of the construction work and shorten the work time by devising the shape of the shaft.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention digs down a pilot hole in a work surface such as a road surface or a floor surface and injects an adhesive into the pilot hole while the small-diameter portion is formed. Anchor part with a tapered surface that is slightly smaller than the diameter of the pilot hole and whose diameter is slightly larger than the diameter of the pilot hole and that slopes toward the distal end and bulges toward the distal end side, and its center A marker body provided with a shaft body provided with a vertical slit along the axis on the back side is arranged on the work surface, and the shaft body is pressed against the prepared hole and the surface of the marker body is pressed to press the surface of the marker body. The marker body is attached to the work surface by reducing the diameter and press-fitting into the prepared hole.

According to the present invention, the marker body disposed on the work surface such as a road surface or a floor surface is dug down on the work surface and is inserted into the prepared hole into which the adhesive has been injected, and the back surface thereof is provided. It is attached to the work surface by fitting the provided shaft body. In more detail, the shaft body has a tapered surface that is slightly smaller than the diameter of the prepared hole and has a tapered surface that is slightly larger than the prepared hole and has a tapered surface that is inclined toward the distal end. Since the anchor portion is provided on the periphery, the anchor portion smoothly fits into the pilot hole along the slope of the tapered surface applied to the peripheral edge of the pilot hole. Along with the downward movement, the large diameter portion of the tapered surface of the anchor portion is pushed from the periphery by the inner wall of the cylindrical pilot hole, and the diameter of the longitudinal slit provided along the central axis approaches, thereby reducing the diameter. And when the back surface of the anchor body is in close contact with the work surface, and the entire anchor portion is fitted into the pilot hole,
The large-diameter portion of the tapered surface is pressed against the inner wall of the prepared hole by the force for restoring outward, so that the shaft body does not come off from the prepared hole.
The marker body is temporarily fixed in the prepared hole until the adhesive injected into the prepared hole is hardened by the action of preventing the shaft from being removed by the vertical slit and the tapered surface, so that the marker body can be prevented from floating.

Therefore, unlike the conventional example, it is not necessary to hold down the surface of the marker body to prevent the marker body from rising, and it is not necessary to perform a complicated screwing operation such as a tapping screw. As a result, the amount of work is reduced accordingly. Work efficiency can be increased and work time can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

The walking guide marker used in the first embodiment of the present invention shown in FIGS. 1 to 3 is a work surface 4 such as a road surface made of concrete or stone material or a floor surface made of flooring material or the like.
It is composed of a convex marker body 1 that is exposed and displayed to guide a visually impaired person, and a shaft body 2 provided on the back side thereof.

The marker body 1 and the shaft body 2 are formed of a rigid material such as brass, aluminum, stainless steel, die cast or the like. The marker main body 1 is a long, convex disk-shaped plate member as shown in FIG. 3, and has a predetermined pattern of irregularities on its surface to prevent slippage. The protruding portions are quadrangular pyramid-shaped projections, which continuously form a knurled pattern. Various irregularities such as stripes at regular intervals can be employed as long as they have an anti-slip function.
Although the marker body 1 of the first embodiment has a long shape used for guidance, it has a circular shape such as a dome shape used for warning and a disc shape having a trapezoidal shape in cross section. Can also be adopted.

A mounting hole 1a is formed on the back surface of the marker main body 1 to receive the mounting base 2a of the shaft body 2, and a female screw engaged with a male screw 2b provided on the outer circumference of the mounting base 2a is formed on the inner periphery thereof. A screw 1b is provided. On the back surface of the marker body 1, a shallow concave portion 1 c is provided at an appropriate position around the shaft 2, and is used as a glue reservoir for the adhesive 7, which will be described later.
This prevents the adhesive 7 from leaking out from the peripheral edge of the marker body 1 when it is pressed from above. The shaft 2 is attached to the marker body 1 at two or three places on the back side of the marker body 1 if it is a long plate as shown in FIG. Is performed only in one place. In that case, the concave portion 1c is provided around the center point.

The shaft body 2 is attached to the marker body 1 with a mounting base 2a.
And an anchor portion 3 embedded in a pilot hole 6 dug down into the work surface 4. Attachment of the shaft body 2 to the marker body 1 is performed in advance separately from the construction of the walking guidance marker,
A product in which both are integrated is commercialized, but the mounting method is not limited to screwing, and various types may be adopted, or both may be integrally formed. If the shaft body 2 is separated as in the present embodiment, the marker body 1 is attached to a tile carpet, a P tile, a rubber plate, or the like to form a unit by replacing the shaft body 2 with another member such as a caulking metal fitting. It has the advantage that it can be used universally. For example, a disk-shaped marker body is commercialized as one unit in which the length and width are 6 × 6, and a long marker body is four units at equal intervals attached to a rubber plate or the like. It should be fixed in a tile shape.

The anchor portion 3 is provided with a plurality of tapered portions 5. The tapered portion 5 has a small-diameter portion A having a pilot hole 6.
The tapered surface 5a, which is slightly smaller than the diameter C and has a large diameter B slightly larger than the diameter C and has a smaller diameter toward the tip, is formed by bulging the tapered surface 5a to the side circumference. The large-diameter portion of the tapered portion 5 is inserted into a prepared hole 6 dug down in the work surface 4.
When it is press-fitted by utilizing the inclination of a and the later-described vertical slit 3b, it has a function of preventing it from coming off. Note that the taper portion 5 is provided at one end, and is provided in a plurality of stages as in the present embodiment, so that the retaining function is strongly exhibited.

The anchor portion 3 is provided with a vertical slit 3b along the center axis thereof. This vertical slit 3b
Is punched out so that the body tip of the shaft body 2 is opened as shown in FIGS. A minus type or a plus type can be adopted, and the screwing work is performed with a screwdriver according to each type. The length of the vertical slit 3b is set so as to slightly leave the base side of the anchor portion 3, and its width is set to about 1 to 2 mm when the maximum diameter of the tapered surface is 5 to 6 mm.

The construction method of the walking guide marker according to the present embodiment configured as described above will be described with reference to FIGS.

First, at an appropriate position on the work surface 4, the diameter C is larger than the entire length of the anchor portion 3 of the shaft body 2 and the diameter C is a tapered portion 5 and a large diameter portion B.
The lower hole 6 which is slightly smaller than the hole is dug down using an electric drill or the like. Prior to the excavation work, a construction gauge or the like in which the drilling positions of the pilot holes 6 are allocated to the installation location of the walking guidance marker may be fixed.

Next, an adhesive 7 is injected into the prepared hole 6 using a dedicated bonding tool. In order to ensure that the bonding is performed, it is necessary to remove excavation dust in the prepared hole 6 by a vacuum cleaner or the like after the excavation operation before the bonding operation.

Thereafter, the marker body 1 is placed on the work surface 4, and the tip of the anchor 3 is applied to the pilot hole 6 and the surface of the marker body 1 is hammered 12 as shown in FIG.
Press with the like. Then, the tapered surface 5a of the tapered portion 5 that comes into contact with the peripheral edge of the pilot hole 6 is smoothly fitted into the pilot hole 6 along its inclination. The anchor portion 3 has a tapered surface 5a in which the small-diameter portion A is slightly smaller than the diameter C of the pilot hole 6, the large-diameter portion B is slightly larger than the diameter C, and the inclined tapered portion 5 swells. Since the vertical slit 3b is also provided, the large diameter portion of the tapered surface 5a is pushed from the periphery by the inner wall of the cylindrical pilot hole 6 as the anchor 3 descends, and the tip of the vertical slit 3b comes into contact with the vertical slit 3b to reduce the diameter. I do. Then, as shown in FIG. 2, when the back surface of the anchor main body 1 is in close contact with the work surface 4 and the entire anchor portion 3 is fitted into the pilot hole 6, the taper surface 5a is enlarged by the force to restore outward. As a result of the diameter portion being pressed against the inner wall of the prepared hole 6, the shaft body 2 is prevented from falling out of the prepared hole 6. The vertical slit 3b and the taper portion 5 prevent the slipping action,
The marker body 1 is temporarily fixed until the adhesive 7 injected into the pilot hole 6 is hardened, so that the marker body 1 can be prevented from floating.

The adhesive 7 is applied to the longitudinal slit 3 of the anchor 3.
In the b and around the tapered part 5
The overflowed portion also accumulates in the recess 1c on the back side of the marker body 1 and hardens, and the walking guide marker is moved to the work surface 4
Firmly.

FIG. 4 shows a main part of a walking guidance marker used in the second embodiment of the present invention. In the marker main body 1 of this embodiment, a rigid core material 8 such as stainless steel is embedded in a hard synthetic rubber material 9. In this embodiment, the shaft body 2 is attached to the marker body 1 by a male screw 2b provided on the outer circumference of the lower half of the mounting base 2a and a female screw 8b provided on the inner circumference of the mounting hole 8a of the core material 8. Not only when the anchor part 3
The synthetic rubber material 9 is sandwiched between the core member 8 and the flange 3c formed on the rear surface on the base side of the above.

In the second embodiment, for this clamping, the diameter of the anchor portion 3 is made slightly larger than the diameter of the mounting base 2a, so that the flange 3c is formed on the base side. .

The diameter of the pilot hole 6 is dug down according to the diameter of the anchor portion 3. The synthetic rubber material 9 on the back side of the marker body 1 is provided with a hole 9a for penetrating the screw-free side periphery of the mounting base 2a.

FIG. 5 shows a walking guidance marker used in the third embodiment of the present invention. In this embodiment, a marker body 1 having a rigid convex body 10 such as brass or stainless steel is used.
And the resin plate 11 loaded in the concave portion 10a provided on the surface side thereof, and the shaft body 3 is formed integrally with the convex disk body 10. The configuration and shape of the anchor portion 3 and the tapered portion 5 thereof are the same as in the first embodiment. The shape of the convex body 10 is a disk shape used for warning or a long shape used for guidance as described in the first embodiment, and the shape of the resin plate 11 loaded therein is also adopted accordingly. Since various colors and shapes of convex portions on the surface of the resin plate 11 can be selected, designability is enhanced, and variations can be widened in combination with the convex disk body 10.

Also in the second and third embodiments, the construction of the walking guide marker is performed by the same method as shown in the first embodiment, and the surface of the walking guide marker is pressed by the same action to prevent the walking guide marker from being lifted. No longer need to be
As a result, the amount of work is reduced, so that work efficiency can be increased and work time can be shortened.

The present invention can be configured in various modes in addition to the embodiments described above. For example, when constructing a walking guide marker where a sheet such as a carpet or carpet is laid on concrete or a floor, etc., extend the base side of the anchor part and penetrate the hole punched in the sheet. Then, the anchor portion of the shaft body is press-fitted into the prepared hole dug down on the work surface such as the floor surface below the seat in the same manner as in the above embodiment. According to this construction method, it is possible to construct the walking guidance marker even in a wide place already laid such as a hotel or a theater where work from the back side of the seat is impossible.

[0028]

According to the method of constructing a walking guidance marker of the present invention, the construction of the anchor portion of the shaft body provided on the marker body is dug down on the work surface by the configuration of the tapered surface and the vertical slit. The marker body is temporarily fixed until the adhesive hardens in the pilot hole.Therefore, there is no need to hold down the surface to prevent lifting, and there is no need for complicated screwing work such as tapping screws. And work efficiency can be increased and work time can be shortened.
