Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one-way long sleeper-like road surface sign for temporarily fixing to a road surface in order to divide a driving lane of an automobile road or to restrict a running area. It is a thing.

[0002]

2. Description of the Related Art A road surface sign formed in one direction so as to be arranged along a lane of a paved road, has a diameter of 15 cm and a length of 0.5 to 1.0 made of polyethylene synthetic resin.
m, a metal patch plate is applied to both inner and outer surfaces along the generatrix of a pipe having a wall thickness of 2 to 3 mm, bolts are inserted into the bolt holes opened at both ends of the pipe, and the above bolts are attached to the nuts embedded in the road surface in advance. It is known that the pipe is screwed in to fix the pipe, and urethane foam is filled inside the pipe (see Japanese Patent Laid-Open No. 3-51405). Besides, there are concrete road markings that are the same as the road surface,
The disadvantages are 1) It is heavy and not easy to carry. 2) It is chipped when the vehicle is shocked while driving and dropped during transportation.
When it becomes powder, it causes dust pollution. 3) If there is a gap between the road surface and the road surface sign, the vehicle will be cracked when the vehicle is running up.

[0003]

It is lighter than concrete and has a load resistance equivalent to that of concrete, is less likely to be damaged, is easy to install and is easy to remove, and has impact resistance, water resistance, Road signs with excellent weather resistance are required.

[0004]

Means for Solving the Problems The present invention has been achieved as a result of intensive studies for solving the above problems, and has a plate shape with a trapezoidal cross section that is long in one direction and can be arranged along the lane of a paved road. Formed of synthetic resin, open the end holes near the both ends of the lower surface in the length direction, penetrating to the upper part,
A mooring fixture made of synthetic resin is laid in the corresponding hole on the road, and it is detachably laid and fixed on the road with anchor bolts.To improve impact resistance, synthetic resin is used. The outer skin of the molded plate-shaped object with a trapezoidal cross section is molded with a hard synthetic resin, the core is molded with a soft synthetic resin, and the trapezoidal cross section of a synthetic resin is formed to further improve pressure resistance. A plate-shaped object with a trapezoidal cross section made of synthetic resin, which is made of synthetic resin and has the same rigid resin as the outer skin of the plate-shaped object and is positioned perpendicular to the road surface and is in contact with the road surface. The outer cover is made of hard synthetic resin, and the core is made of a divided object of soft synthetic resin in order to improve the efficiency of manufacturing the core, making it easy to attach and remove road markings and road surfaces. In order to open at both ends of the road markings made of synthetic resin. A road surface labeled and mounting method anchor bolt is characterized in that it consists of synthetic resin end corresponding to the hole and the end portion hole for fixing the anchoring fixture on laying roads. The production of the core body includes the production of waste of thermoplastic synthetic resin by crushing, mixing, melt-extruding, casting, cooling press and demolding.

The present invention will be described with reference to the drawings. FIG. 1 is a plan view of a road marking 1 made of synthetic resin, which is mainly installed in a median strip. It is also possible to use the trapezoidal cross section of FIG. 1 on the shoulder in a form such that it is divided into two in the length direction.
It can also be used in a parking lot by laying it in a U shape. With the main body anchoring holes 2 located at both ends, the main body anchoring holes 2 are anchored and fixed to the corresponding holes on the road through the main body bolt holes connected to the anchoring holes.

FIG. 2 is a sectional view taken along the line AA of the road marking of FIG. 1. The outer cover 3 is made of a hard synthetic resin, and the hard synthetic resin preferably has a Rockwell hardness of 100 to 120 degrees. It is desirable that the synthetic load resistance of the core made of the outer cover and the soft synthetic resin is 3 tons or more.

FIG. 3 is a partial cross-sectional view for explaining the anchoring and fixing of the road marking 1 and the road surface. The anchoring protector 6 is often made of epoxy resin in the embedding holes B on the road surface corresponding to the anchoring holes 2 at both ends of the road marking 1, but the invention is not limited to this. A stabilizing disk 9 is provided to maintain the stability of the road markings on the main body. The diameter of the disk should be slightly smaller than the diameter of the anchorage protection. The thickness of the stabilizing disk is preferably 50% to 90% of the depth of the tethering / fixing protector. The method of anchoring the road surface sign and the road surface is a bolt nut method, and either a metallic one or a synthetic resin one can be used, but from the viewpoint of removal, the synthetic resin one is preferable.

FIG. 4 is a cross-sectional view of a road marking which is reinforced by ribs to improve load bearing capacity. A plurality of strength bones 10 are provided. Made of the same hard synthetic resin as the outer skin 3. For the core body, a divided core body is made in advance and is inserted and bonded between the ribs. However, the present invention is not limited to this, and the core body may be cast integrally. By embedding a reflection plate (cat's eye, cat's eye) on the surface of the nut 8 of the main body anchoring hole 2, the nighttime distinguishability is improved.

FIG. 5 is a partial cross-sectional view of the bolt 7 for anchoring and fixing the road marking body and the road. When making with synthetic resin,
Trapezoidal screw holes have less wear and damage than triangular ones, and have excellent durability.

In the drawings, the description has been given only as a road marking,
It can be used both on the shoulder and in the parking lot by changing the shape slightly. An arbitrary color can be obtained by applying a pigment to the road marking. Further, by applying the fluorescent paint, it becomes possible to clearly distinguish the oncoming lane as a road sign even at night.

[0011]

[Function] By anchoring two anchor bolts on the road surface at predetermined intervals with the anchoring holes of the road marking main body, there is an effect of shock absorption on the stepping of the wheel of the automobile, and there is a risk of split damage. Instead, it acts as a road marking.

[0012]

[Effect] Since the road marking is made of synthetic resin, the marking will not be damaged even when the wheel is stepped on, and abnormal deformation of the wheel will not occur. Also, since it is easy to put on and take off, it is possible to respond quickly.
