Description

  The present invention is, for example, for securing a sidewalk, installed at the boundary between a roadway and a sidewalk, installed in a park or the like for prohibiting entry of a vehicle, or installed as a protective fence for a vehicle, a centerline of a roadway, Used for signposts (hereinafter simply referred to as “car stops” etc.) installed on the road surface to indicate separation zones, etc., and has moderate strength and flexibility, making it difficult to be damaged even when hit by a vehicle. It relates to a resin pole.

  Conventionally, poles used for car stops etc. have been made of metal, stone pillars, etc. such as iron, stainless steel, aluminum, etc., but the manufacturing cost is bulky and considerable damage to the pole or the vehicle itself due to the car that touched it There was a difficulty to give.

In order to cope with this problem, Patent Document 1 discloses a vehicle stopper that forms a plastic layer on the outer periphery of a metal tube, and Patent Document 2 discloses a polyurethane body inside a tubular body made of a rigid resin such as polyethylene. A marker column provided with a tubular restoring member made of an elastic body is disclosed. Of these, the former car stopper is fixed to the ground by placing concrete around the exposed metal pipe on the lower side, and the latter marker pillar has the main body and the resilience imparting member at the lower end and the upper base member And a lower base member are fixed, and the base is inserted into an anchor bolt projecting from the road surface, and fastened with a nut to be fixed. Then, by removing the upper base from the lower base, the main body can be removed, or the resilience imparting member can be removed to allow partial replacement of parts.

  The former car stopper has a sufficient strength as a car stopper by embedding a metal tube as a reinforcing material inside, and has a suitable shock absorption property by a plastic coating layer, but on the outer periphery of the metal pipe Covering the plastic layer has a complicated structure, increases the manufacturing process, increases costs, and is fixed to the ground with concrete, so it is not easy to replace the plastic layer.

  The latter sign post also consists of a main body and a resilience imparting member. At the time of installation, the lower end of the main body and the resilience imparting member is sandwiched between the upper base and the lower base and fixed with a set screw or a rivet. In addition, the sign post and its mounting structure are complicated, and there is a problem that it takes a considerable amount of time to install and remove it.

  An object of the present invention is to provide a resin pole that is used as a car stopper or the like, has a simple structure, and can be easily attached and detached.

  The invention according to claim 1 has a moderate strength and flexibility and is used for a car stop or the like, and at least a lower end portion is formed in a hollow tubular shape and is a resin pole such as polyethylene, A lower end is removably inserted into a resin, preferably a metal mounting part, which is fixed to the ground or fixed to a portable concrete block, and is fixed to the mounting part by a fastening means such as a screw. It is characterized by being.

  According to the present invention, the entire pole is made of resin, and is fixed by being inserted into the mounting portion and fixed, and is fixed to the mounting portion, so that it has a special structure, for example, a flange is fixed or integrated Therefore, the structure is simple, and the fixing is performed by a fixing means such as a screw, so that attachment and removal can be easily performed.

  The resin pole of the present invention has a decorative property, a sign function, or a pattern, characters, figures, symbols, etc. for easy identification even at night. May be applied or mixed, or a symbol or the like, or a film or sheet to which a fluorescent paint is applied may be attached to the whole or a part of the pole. Further, carbon black or the like may be mixed in order to give an ultraviolet resistant effect.

The invention according to claim 2 is characterized in that, in the invention according to claim 1, the mounting portion is fixed to the ground with concrete, or is inserted and fixed to an anchor bolt protruding from the concrete block,
The invention according to claim 3 is characterized in that, in the invention according to claim 1, the mounting portion is fixed to the metal pipe embedded in the ground or the concrete block so as to be fixed or removable.

  According to a fourth aspect of the present invention, in the first aspect of the invention, the lower mounting portion is fixed to the ground or the concrete block, and the upper mounting portion is connected to the lower mounting portion with a bolt. It is characterized by being.

  According to the first aspect of the present invention, since it is light and does not corrode, and it is not necessary to provide a special structure such as providing a flange for mounting on the mounting portion, the structure is simple, easy to manufacture, and low cost. It has sufficient strength as a vehicle stopper, etc., and even if it comes into contact with the vehicle, it is difficult to be damaged by bending, and it can be attached or removed by fastening means, and can be easily attached or replaced. Recycling is also possible.

  In the invention which concerns on Claim 2 or 3, in the thing which made it possible to remove an attaching part, the pole from which a diameter differs can be attached by replacing with the attaching part corresponding to the diameter of a pole.

  Similarly, in the invention according to claim 4, poles having different diameters can be mounted by replacing the upper mounting portion.

  The pole 4 shown in FIG. 1 is made of a polyethylene pipe, and the same polyethylene cap 5 is fixed to the upper part by butt fusion.

FIG. 2 shows the mounting portion 1 for fixing the pole 4 shown in FIG. 1, which is made of steel, has a concave cross section, has a flange 1a protruding laterally at the lower end, and has concrete 7 on the ground. It is inserted into the anchor bolt 2 fixed by the above and is fixed by tightening the nut 3.
The pole 4 is fixed to the mounting portion 1 by inserting the pole 4 into the mounting portion 1 from above and screwing in a screw 6 as a fastening means.

  According to the pole of the present embodiment, the whole is made of polyethylene, is light weight, does not corrode, does not need to have a special structure to be attached to the attachment portion, and can remain a tubular shape, so the structure is simple and easy to manufacture. It can be obtained at a low cost, has moderate strength and flexibility, has sufficient strength as a vehicle stop, etc., and even if it comes into contact with the vehicle, it can be damaged by bending. It is difficult to attach, and can be easily attached and removed by tightening or loosening the screw 6 by inserting it into the attachment part. It is easy to install and replace, and can be recycled. Since it can be removed by loosening, when mounting a pole with a different diameter, it is possible to attach a pole with a different diameter by replacing the mounting part corresponding to the diameter of the pole. It can be found an effect equal.

  The attachment portion 11 shown in FIG. 3 has the same structure as that of the attachment portion 1 shown in FIG. 2. The attachment plate 13 is fixed to the steel pipe 12 embedded and fixed in the ground by welding. In the same manner as the attachment portion 1 shown in FIG. 1, the anchor bolt 14 is inserted into the anchor bolt 14 and fixed by welding, and is fixed by the nut 15. The pole 4 is fixed in the same manner as described above.

  The mounting portion 21 shown in FIG. 4 is composed of an upper mounting portion 21a and a lower mounting portion 21b having the same structure as the mounting portion 1 or 11 shown in FIG. 2 or 3, and the lower mounting portion 21b is formed in the outer tube 22a. The steel tube 22 is inserted into the inner tube 22 b of the inner tube 22 b to be inserted, and is fastened by screws 23. The upper mounting portion 21a is overlapped on the lower mounting portion so that the flanges are joined to each other, and is detachably connected to the lower mounting portion 21b by bolts 23 and nuts 24. Also in this case, the pole 4 is fixed to the upper mounting portion 21a in the same manner as described above. In the figure, 25 is a collar for fixing the lower mounting portion 21b fitted to the outer tube 22a, and 26 is an eyebolt to which a chain connecting the poles is connected.
