Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roadbed body which is laid on a road surface to prevent freezing slip.

[0002]

2. Description of the Related Art Conventionally, as a measure for preventing roads from freezing in order to prevent slippage, a heater is buried under the road surface to perform road heating.

[0003]

However, in addition to the laying cost and maintenance cost of road heating, when the surface forming layer of the road is asphalt, it is weakened by the high temperature at which road heating occurs and the asphalt is damaged. It is easy to do so, and there is a risk that the embedded road heating equipment will also be damaged, and in the case of a concrete board that is resistant to temperature changes, on the other hand, the thermal efficiency is very poor, and it was expected that a huge amount of energy was required. There is a problem that it cannot be effective. There is also a problem that maintenance of these facilities is difficult due to lack of manpower.

[0004]

According to the present invention, a concrete board formed for road construction is provided with fitting grooves at intervals, and a rubber body is fitted into the fitting groove so as to form the same plane. In addition, a paragraph groove is provided in the groove opening portion of the fitting groove, and the upper peripheral surface of the rubber body is exposed by the paragraph groove, and the problem is solved.

[0005]

The roadbed body for preventing freezing and slipping of the present invention is mainly laid on a road in a cold region and crushes ice on a frozen road surface to prevent slipping.

Since the rubber bodies to be fitted on the concrete board at intervals are arranged so that the upper surface is aligned with the upper surface of the concrete board to form the same plane, when the concrete board is laid to construct a road, And the icing on the rubber body are the same, and this icing is that the upper part of the rubber body that appears in the paragraph groove is elastically floated and deformed by the treading pressure of the traveling vehicle to sequentially crush the frost and prevent slipping. Become.

[0007]

An embodiment will be described below with reference to the drawings.

FIGS. 1 and 2 show a first embodiment of the present invention. A fitting groove having a convex shape in a side view with a space provided between parallel ends of a concrete board 1 formed in a square shape in a plan view. 2 is provided, and a rubber body 3 having substantially the same shape is fitted in each fitting groove 2, and the upper surface of the rubber body 3 is aligned with the upper surface of the concrete board 1 to form the same plane.

Reference numerals 4a and 4b are paragraph grooves formed by notches in groove openings on both sides in the longitudinal direction of the fitting groove 2, and the upper peripheral surface of the rubber body 3 is exposed from the paragraph grooves 4a and 4b. 5 is a groove provided in the middle of the upper surface of the rubber body 3, 6 is a hollow hole provided in the middle of the rubber body 3 in the longitudinal direction, 7 is a metal plate embedded in the widened bottom portion, 8
Reference numerals a and 8b are reinforcing bars arranged in the concrete board 1.

Concrete board 1 thus formed
When it is laid for road construction in cold regions, ice forms continuously on the upper surfaces of the concrete board 1 and the rubber body 3 that form the same plane due to cold, and this ice is the upper part of the rubber body 3 when the traveling vehicle steps on the rubber body 3. Is a groove 4 as shown in FIG.
a and 4b are swelled and deformed while being elastically sunk and levitated to the original position by the passage of a vehicle, and in the duplication thereof, the ice on the rubber body 3 is crushed into pieces, and the ice on the concrete board 1 is also rubber. As the ice on the body 3 is crushed, it is crushed. Incidentally, FIG. 3 (b) shows a case where the paragraph grooves 4a and 4b are not formed on both sides of the rubber body 3, and the rubber body 3 is surrounded by the concrete board 1 and hardened by the concrete board 1 and the fitting groove 2 is formed. Since the frontage of the groove is narrow, even if the traveling vehicle passes through it, the concrete board 1 receives the stepping pressure and the rubber body 3
The ice does not float, so the ice is not shattered.

FIGS. 4 to 5 show a second embodiment of the present invention, which is a circular groove 2 having a convex cross section on a concrete board 1.
Multiple a's are provided at intervals, and a circular rubber body 3a having substantially the same shape is fitted in each circular groove 2a, and the upper surface is aligned with the upper surface of the concrete board 1.

Reference numeral 4c is a paragraph circular groove formed by notching the groove opening of the circular groove 2a, and the upper portion of the rubber body 3a is exposed from the concrete board 1 from this portion. Other configurations and operations are the same as those in the first embodiment.

[0013]

As described above, according to the present invention, a rubber body is fitted to a concrete board formed for road construction in cold regions so as to form the same plane, and the upper portion of the rubber body is placed on the concrete board. Since it was exposed from the paragraph groove provided,
The upper part of the rubber body elastically floats and sinks due to the treading pressure of the traveling vehicle to crush the ice on the upper surface, and as a result, the ice on the concrete board is also crushed. The effect is that friction can be maintained and slip can be prevented.
