Description

Road marker {road stud}

The present invention relates to a road sign bottle, and in more detail, the upper surface is narrow and the lower surface is inclined so as to be inclined so as to be integrally injection-molded into the form of the reinforcing steel plate embedded into the inside of the rectangular body portion, vertical entry into the lower portion The reinforcing steel pipe for reinforcing the vertical column is also embedded inside the vertical column, and the bottom of the vertical column is coupled to the anchor to be firmly fixed on the ground, thereby preventing frequent breakage of the main body and the vertical column to be buried. The present invention relates to a road sign bottle that can prevent safety accidents due to increased durability and departure from impact.

In general, road markers are installed at the center line of a road or on a segmented lane of a divided road to induce safe driving by allowing the driver to clearly identify the partition line of the road by reflecting light from the reflector of the road marker at daytime and at night. It provides a function.

Such road marker bottles are manufactured in various shapes and materials and are used based on a method of fixing them at regular intervals along the divided lanes of paved roads, and representative examples thereof are shown in FIGS. 1A and 1B. It has an approximate configuration consisting of bolts 3 for fixing the trapezoidal body 1 with the reflector 2 on the side to the road surface.

Such a conventional road marker bottle is fixed by driving a bolt (3) in the hole in a state in which holes are formed at regular intervals along the partition lane on the paved road surface, and bonds an adhesive such as a bond for more perfect fixing. ) It is applied to the bottom surface and is fixed to be integral with the road surface.

In addition, a cover bottle in which the body 1 and the lower buried body 4 are integrally formed is also presented, which is also installed in a forced type in a perforated hole on the road.

However, the conventional road sign bottle installed as described above is formed by simply injection molding the body with a synthetic resin, etc., when the driving car crosses the wrong lane and gets stuck on the wheel, the body is damaged by the load of the car and continuously Of course, there is a problem in that the waste of resources and excessive expenses of the repair costs are caused.

In addition, the strength is significantly reduced as time passes, and if the body is damaged by the driving shock of the car passing over it, only the bolt remains, and in the latter case, the buried body protrudes when the cover bottle is turned over. As a result, subsequent vehicles passing over them often resulted in car tire punctures, which often led to large accidents.

Accordingly, the present invention has been invented in view of the above problems, and is molded into a double injection structure in which a reinforcing iron plate and a reinforcing steel pipe are embedded into the main body portion, thereby improving durability and ensuring stability while allowing the long-term use of a label bottle. The purpose is to save resources and to reduce maintenance costs.

In addition, by strengthening the strength of the body portion, by reducing the vehicle impact load applied to the cover bottle in the event of a collision of the vehicle to prevent damage to the cover bottle, to reduce the impact and vibration transmitted to the vehicle, and to the projection to the lower center of the body portion It is another object to form a vertical column formed, by further engaging the anchor portion to the lower end to increase the buried depth to be firmly fixed on the ground, and not to be detached by the impact of the vehicle.
