Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road mat.

[0002]

2. Description of the Related Art For example, when the scaffold becomes unstable on a soft ground or when the ground is flooded or covered with earth and sand due to wind and flood damage, a hard mat material is laid on the ground and temporarily installed. Road surface is provided. As the mat member, there is known a material in which an iron plate having an appropriate width is formed into a long length, a material in which the iron plates are connected by a reinforcing bar and combined, or a resin plate-shaped body.

However, when the mat member is made of an iron plate or a combination product of an iron plate and a reinforcing bar, there is a problem that it is difficult to walk on the uneven ground because it is poor in flexibility and difficult to walk. In addition, water or the like may accumulate on the upper and lower surfaces of the mat member and cause rust, or pedestrians may slip. In addition, since the weight of the mat itself is large, when it is laid on a slope or the like, it may be difficult to fix it on the road surface and it may slip off under its own weight. Further, since the shape is uniform, there is a problem that it is difficult to adapt to the shape of the road such as a corner or a curved road. On the other hand, many resin plate-like bodies are small, and a road surface mat that can cover a wide road surface has been desired.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve such a problem, and it is possible to reliably drain water even on soft ground, uneven roads or slopes. It is an object of the present invention to provide a road surface mat that is laid, can be safely passed by pedestrians and vehicles without slipping, and can be appropriately adapted to various road shapes such as corners and corners.

[0005]

That is, the present invention provides:
A plurality of soil insertion holes formed through almost the entire front and back surfaces, anti-slip projections formed on the peripheral surface of each soil insertion hole, fixing holes formed through the edges of the front and back surfaces, and side surfaces. The present invention relates to a resin plate-shaped road surface mat having formed connecting holes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. 1 is a front view showing an example of a road mat of the present invention, FIG. 2 is a rear view thereof, FIG. 3 is a sectional view taken along line 3-3 of FIG. 1, and FIG. 4 is a sectional view taken along line 4-4 of FIG. , Fig. 5
6 is a cross-sectional view showing a connected state of the road mat, FIG. 6 is a cross-sectional view showing a state in which the road mat is laid on a slope, FIG. 7 is a perspective view showing another example of the present invention, and FIG. FIG. 9 is a front view showing another example, and FIG. 9 is a plan view showing the connected state.

As shown in FIGS. 1 to 4, a road mat 10 according to the present invention includes a plate-shaped mat body 11 having a plurality of soil insertion holes 12, slip preventing projections 13 and fixing holes 1.
4 and a connecting hole 15.

The mat body 11 is made of a hard synthetic resin, and is formed in a plate shape of a substantially quadrangular shape having a width that allows vehicles and the like to pass through.

A plurality of soil insertion holes 12 are formed so as to penetrate almost the entire front and back surfaces of the mat main body 11, and when the road mat 10 is laid on the ground, soil enters inside thereof. There is. As a result, even when the road surface mat 10 is arranged on, for example, a bumpy road surface or soft ground, the road surface mat 10 can be stably installed. Further, when laid on a slope or a flooded road surface, it is possible to prevent the outflow of earth and sand and the slipping of the road mat 10. Furthermore, this soil insertion hole 12 also effectively acts to prevent drainage of the mat and prevent rainwater and the like from collecting on the front and back surfaces of the mat and causing pedestrians to slip and soften the ground. In this example, the soil insertion hole 12 is formed in a substantially hexagonal shape, but it can be formed in a desired shape depending on the condition of the road surface to be laid.

The non-slip protrusions 13 are formed on the mat body 1 as described above.
On the surface side of 1, a plurality of holes are provided around the soil insertion hole 12. The anti-slip projections 13 are provided to prevent slipping when a pedestrian, a bicycle, or the like passes by on the road mat 10, and has two or more types of pin shapes having different heights. In this example, as shown in FIG. 4, a high pin and a low pin are provided alternately. By forming the non-slip protrusions 13 in the shape of pins having different heights, it is possible to provide a road surface mat that easily bites into a shoe sole or the like and is hard to slip during walking.

The fixing holes 14 are provided at the edges of the mat main body 11 so as to penetrate the front and back surfaces thereof, and the piles or the like are driven to fix the road mat 10 on the ground. In this example, the fixing holes 14 are provided at the four corners of the mat body 11.

The connecting hole 15 is provided on the side surface of the mat body 11 so as to penetrate the inner surface and the outer surface. The connection hole 15 is suitable when a plurality of road surface mats 10 are connected and used according to the shape of the road. That is, as shown in FIG. 5, one road surface mat 10 and another road surface mat 10 are provided adjacent to each other with the connecting holes 15 and 15 aligned, and the fixing bolt B is connected to the connecting hole 15 and A desired number of sheets can be connected by penetrating 15 and fixing with a nut N.

Further, as can be understood from FIG. 6, if the hole diameter of the connecting hole 15 is formed larger than the screw diameter of the fixing bolt B, the freedom of connecting the road mats 10 and 10 is increased. Since it is provided, it can be installed according to the inclination of the slope. Further, as shown by a chain line in the drawing, a packing 18 made of rubber or the like is attached to the fixing bolt B, and the road surface mat 10 is connected through the packing 18, whereby the road surface mats 10 are directly connected to each other. It can prevent hitting and improve durability.

FIG. 7 shows another example of the present invention.
The mat body 31 of the road mat 30 is divided into three parts, a central part 32 and both side parts 33, 33,
The central portion 32 has a step shape having a step portion 36.
Reference numeral 34 is a soil insertion hole. According to the road surface mat 30 having this structure, the central portion 32 can be preferably used as a passage for pedestrians, and the both side portions 33, 33 can be preferably used as traveling paths for four-wheeled vehicles such as automobiles. When a pedestrian passes through the central portion 32, the stepped portion 36 rests on the foot, so that the pedestrian can walk safely without slipping. Further, since there is no step 36 on both side parts 33, 33, an automobile or the like can travel safely. It should be noted that it is convenient and easy to walk if the intervals at which the step portions 36 are provided are adjusted to the stride of an average person.

FIG. 8 shows another example of the present invention.
A road surface mat that is preferably laid on a curved portion of a road. Reference numeral 40 is a road mat, 42 is a soil insertion hole,
Reference numeral 43 is a non-slip projection, and 44 is a fixing hole. The road mat 40 has a substantially trapezoidal planar shape, and can be formed into an appropriate curved shape by connecting a plurality of upper sides 45 and lower sides 46 together as shown in FIG. it can. The upper side 45
If a road surface mat is prepared by appropriately changing the difference in length between the lower side 46 and the lower side 46, it can be freely applied even when the curve is steep. Further, by arranging the upper side 45 and the lower side 46 alternately, it is possible to form a straight road surface.

[0016]

As shown and described above, according to the road surface mat of the present invention, since the earth and sand enter the soil insertion hole, it can be surely laid on the soft ground or the road surface having a lot of unevenness. Further, since the surface is provided with the non-slip projections, pedestrians and vehicles can pass safely without slipping. Furthermore, if the road mat is formed in an appropriate trapezoid, it can flexibly cope with various road shapes such as curves and corners.
