Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to plastic piles, especially plastic piles that are used for multiple purposes such as marking the boundaries of fields, etc., and enclosing surrounding areas. .

(Prior art) Plastic piles with a plastic cap on the top end of a cylindrical or prismatic plastic pile body have been proposed for purposes such as land boundary marking and surveying (for example, in 1973). −29683
number, etc.).

(Problem that the invention aims to solve) However, when driving stakes for surveying or boundary marking in fields or mountainous areas, it is often necessary to transport a large number of stakes manually. However, cylindrical or prismatic plastic piles are bulky, so it is inconvenient to transport them manually. In addition, the surface of plastic stakes is slippery, so if you tie marking tape or rope to the stake, the tape or rope may slip off, and if you write letters or symbols on the surface of the stake, they will quickly disappear. There was a problem.

Therefore, the purpose of this invention is to solve the above-mentioned problems by creating a structure that is easy to transport, does not fall off even when tape or rope is tied to the stake, and also allows characters and symbols to be written on the surface of the stake. To provide a plastic stake that is possible and in which written characters and symbols do not disappear.

(Means for Solving the Problems) That is, the present invention is a plastic pile consisting of an elongated plate-like body having a tapered portion at its tip, the plastic pile having a through hole in the upper part,
A pair of latching recesses are provided on the upper side surface, and a plurality of grooves are provided along the length of the tapered portion, and at least a portion of the upper surface of the plate-like body is matted. It's a plastic stake.

(Function) According to this invention, instead of the conventional cylindrical or prismatic plastic piles, they are shaped like elongated plates, and because through holes are provided in the upper part of the plates, a large number of through-holes are provided. By stacking plastic stakes,
A large number of plastic stakes can be easily transported at once by passing a net through each through hole. Furthermore, since a pair of latching recesses are provided on the upper side of the plastic stake, if tape or rope is tied to the pair of latching recesses, the tape or rope will not come off. Furthermore, since at least a portion of the upper surface of the plastic stake is matte, it is possible to write letters and symbols on this portion, and the written letters and symbols will not disappear.

(Example) Next, an example of the plastic pile of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a plastic pile, in which a tapered portion 2 is formed at the tip of an elongated plate-like member 1. The plate-shaped body usually has a thickness of 3 to 15 mm, and a suitable length to width ratio of 5 to 15. Reference numerals 3 and 3' designate a pair of hooking recesses provided on the side surfaces of the plate-like body 1 in the upper part thereof, and in FIG. 1, one set is provided. This latching recess is usually 10 to 60 mm wide and 1 to 60 mm deep.
It is a 10mm recess, and its width and depth are determined by the purpose of use. Further, a plurality of sets of latching recesses may be provided at vertical intervals. 4 is a groove to reduce the resistance of the soil when driving plastic piles, and is usually 5 to 10 mm wide and 2 to 5 mm deep.
Eight pieces are provided in the tapered part 2 of the plate-like body along the length direction. The groove may extend close to the top of the plate as shown in FIG. 5 is a through hole with a diameter of 5 to 15 mm bored in the upper part of the plate-like body.
In addition, a part of the upper surface of the plate-like body, the area 7 surrounded by diagonal lines in Fig. 1, is matted (matte), and characters and symbols can be written on this area. The symbol never disappears.
The matte finish may be applied to a part of the upper surface of the plate-like body, as shown in FIG. 1, or to the entire surface. The portion to be matted is determined as appropriate depending on the size of the plate or the number of characters or symbols to be written. In addition, when using the plastic pile of this invention for surveying,
The center hole 6 of the measurement point confirmation table is located at the center of the upper end surface of the plate-shaped body 1.
It is necessary to provide Since the plastic pile of the present invention is easy to transport, it can be suitably used as a surveying or marking pile in fields or mountainous areas.

The plastic that forms the plate-shaped body is as follows:
Known plastics such as polyethylene, polypropylene, polyvinyl chloride, polyethylene and polycarbonate are used. Among them, polypropylene is preferably used because it is inexpensive, has high strength, and has excellent weather resistance.

(Effects of the invention) As described above, the plastic pile of the invention is (1) lightweight because it is a plate-shaped body; (2) Since a pair of hooking recesses or a plurality of pairs of hooking recesses are provided at the upper part of the plate-like body, if tape or rope is tied to the hooking recesses, the tape or rope can be tied to the hooking recesses. The rope never comes off. (3) Since through-holes are drilled in the upper part of the plate-like body, it is easy to transport a large number of plastic piles by passing a rope or the like through the through-holes. (4) Since a part of the upper surface of the plate-shaped body is matte, it is possible to easily write letters and symbols on this part. (5) Since it can be manufactured by compression molding, it is highly productive and can provide inexpensive piles. It has excellent effects such as, and is suitably used for surveying, marker stakes, boundary stakes, marker stakes, etc.
