Hereinafter, the marking pile of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing the entire marking pile according to one embodiment of the present invention. This marking pile A has a sharp tip 11 on the tip side of a slender, for example, cross-shaped pile main body 1, and a square pole-shaped head 10 exposed on the ground surface when embedded in the ground G, on the other side. The head 10 has a cap 12 made of metal or resin. The cross-sectional shapes of the pile main body 1 and the cap 12 can be various shapes such as a triangle, a polygon having four or more squares, and a circle.
[0014]
On the top surface 12a of the cap 12, characters and symbols 12b such as the type of the marking pile A, the name of the affiliation or the name of the land being driven are engraved. Is engraved.
[0015]
The pile main body 1 is made of resin or concrete, and usually, the one made of resin is suitably used. As a material of the resin-made pile main body 1, for example, a recycled resin obtained from waste of a resin product molded of a thermoplastic resin such as polyethylene, polypropylene, polyester, styrene, polyamide, and polysulfonic acid is used. As a material for the cap 12, a thermoplastic resin such as polyethylene, polypropylene, fluorine, polycarbonate, polysulfone, or polyester, or a thermosetting resin such as phenol or polyimide is used.
[0016]
A rectangular recess 2 which is long in the vertical direction is formed on a side surface of the head 10 and a concrete display board 3 is fitted therein. The display plate 3 is provided with an identification mark 31 such as an identification number of the marking pile A or a symbol. In this embodiment, a numeral “125” indicating the identification number of the marking pile A is engraved.
[0017]
FIG. 2 is a cross-sectional view taken along line XX of FIG. 1 and shows a state in which the display plate 3 is removed. In order to prevent the display plate 3 fitted into the recess 2 from coming out of the recess 2, recesses 2 are formed on both left and right sides of the peripheral edge of the recess 2, on the outer side S of the recess 2. An engaging groove 21 having a U-shaped cross section to be inserted is formed. One side surface 21 a of the locking groove 21 is continuous with the bottom surface 20 of the recess 2. The locking groove 21 may be formed on the upper and lower portions of the peripheral edge of the recess 2 or may be formed on the entire periphery of the peripheral edge.
[0018]
FIG. 3 is a cross-sectional view showing another example of the recess 2. As shown in the figure, the locking groove 21 may be formed in a dovetail cross-sectional shape inclined obliquely outward of the recess 2 from the outer surface of the head 10 toward the bottom surface 20 of the recess 2. .
[0019]
FIG. 4 is an enlarged front view showing a bottom surface portion of the recess 2. FIG. 5 is a side sectional view taken along line YY of FIG. As shown in these figures, the bottom surface 20 of the recess 2 is improved in biting of the bottom surface 20 of the recess 2 of the display panel 3 (anchor effect) and slips off from the recess 2 of the display panel 3. In order to prevent this, a plurality of horizontal ribs 22 extending in a direction substantially perpendicular to the axis C of the head 10 and a vertical rib 23 extending in a direction substantially along the axis C are formed. In particular, the horizontal ribs 22 provide a large resistance to the downward movement of the display panel 3. Instead of the horizontal and vertical ribs 22 and 23, a horizontal groove or a vertical groove may be formed on the bottom surface 20 of the recess 2.
[0020]
Next, a method for manufacturing the above-described marking pile A will be described.
In the side sectional view shown in FIG. 6, first, a gel-like display plate material, for example, a concrete material 4 such as mortar, which is to be the display plate 3, is formed on the head 10 of the pile main body 1 at the burial site or factory. The entire recess 2 is painted and embedded so as to be substantially flush with the outer surface of the head 10. Next, before the concrete material 4 is solidified, a stamp 5 having a convex portion 51 serving as the identification mark 31 of the display panel 3 is used, and the stamp 5 is pressed against the concrete material 4 and the convex portion 51 is pressed. Is stamped on the concrete material 4 by. The stamp 5 is created, for example, by preparing ten types of stamp pieces 50 having convex portions 51 representing numbers 0 to 9 and selecting a plurality of stamp pieces 50 and fitting them into the stamp base 52. Thereafter, by solidifying the concrete material 4, the display plate 3 provided with the identification mark 31 is attached to the recess 2 of the head 10 in an embedded manner.
[0021]
As described above, the concrete board 4 is applied to the recess 2 of the pile main body 1 and the convex portion 51 of the stamp 5 is pressed before the concrete material 4 is solidified, so that the display board 3 is embedded in the recess 2 even at the burial site. The marked marking pile A can be easily obtained. A locking groove 21 is formed at the periphery of the recess 2 so as to be recessed toward the outer side S shown in FIG. 2, and the concrete material 4 applied to the recess 2 in the locking groove 21 is formed. Since a part is filled, the concrete display plate 3 fitted in the recess 2 is partially engaged with the locking groove 21. Thereby, the display plate 3 is securely and firmly attached to the recess 2. Further, since a plurality of horizontal ribs 22 and vertical ribs 23 are formed on the bottom surface 20 of the recess 2, the display plate 3 is prevented from sliding down by the anchor effect of the ribs 22 and 23, and the display plate 3 The mounting strength to the marking pile A is increased.
[0022]
The material of the display panel 3 is not limited to concrete. For example, a gel or chewing gum resin such as a chemical reaction adhesive can be used as the display panel material. As such a material, there is "Mitsutaro (trade name)" manufactured by Sanko Techno Co., Ltd. This material is composed of two kinds of resins, epoxy and polyamide. When these resins are mixed and left in a gel state, they dry and solidify.
