Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a road base material that can prevent the generation of dust and noise caused by the running of vehicles.

<Prior Art> As is well known, paved roads are made by laying a mixture of limestone powder, crushed stone, sand, and asphalt to an appropriate thickness, and then flattening the mixture with rollers or the like.

In snowy and cold regions, the surfaces of the paved roads mentioned above often become frozen during the winter, so chains are wrapped around vehicle tires to prevent slip accidents. Or regular tires are replaced with spiked tires to prevent slipping.

<Problems to be Solved by the Invention> However, when such chain respif tires are driven on roads without snow, they scrape the road surface due to friction etc., creating unevenness on the road surface.

There is a high risk of accidents such as the steering wheel being stolen, and powder from scraped asphalt, etc., or iron powder from chains and spiked tires becomes dust, causing new pollution and causing a major social problem. It became.

<Means for solving the problem> The present invention aims to solve the above-mentioned conventional problems. , each wooden block is arranged side by side in the front-rear direction and left-right direction so that the through holes of the blocks communicate with each other, and the binding material is inserted in a series through the through holes of each of the communicating wooden blocks, and the ends of the binding material are made of wood. It consists of an upper roadbed fixed to the side surfaces of the blocks, and a lower concrete roadbed provided with holes into which the lower portions of the wood blocks are individually fitted.

<Example> Embodiments of the present invention will be described below based on the drawings.

The road bed material 1 of the present invention is composed of an upper road bed 2 formed by bundling a large number of wooden blocks 3 into a panel shape, and a lower road bed 10 that supports the lower part of the upper road bed 2. The wooden block 3 is made by cutting a log into rounds at a predetermined length, or cutting a square lumber crosswise.

A cross-shaped through hole 4 is formed at a slightly upper part of the height of this wooden block 3, but these two through holes 4 are at the same height and do not communicate at the center; 4, the other through hole 4 is located below by the diameter of the through hole. and,
A U-shaped groove 5 is provided around the circumferential surface of the wooden block 3, and the opening ends of the above-mentioned two-way holes 4 are located within this U-shaped groove 5.

In addition, a fitting part 7 is provided hanging down at the lower part of the wooden block 3, but this fitting part 7 has a diameter smaller than the diameter of the upper part when the wooden block 3 is a log; In this case, the length of one side is set to a smaller value than the length of one side of the upper part, and the wooden block 3 made of square lumber is
In this case, a notch 6 is provided in the upper corner along the length direction.

Since the wooden block 3 is made of wood, it must be protected against corrosion and abrasion, and if necessary, it may be coated with or impregnated with a corrosion inhibitor or hardening agent that is harmless to humans and animals.

Each wooden block 3 having such a configuration is
The through holes 4 of the wooden blocks 3 are arranged in parallel in the front-rear direction and the left-right direction so that they communicate with each other, and the binding material 8 made of steel or the like is inserted in series into the through hole 4 of each wooden block 3 that communicates with each other. are fixed to the side surfaces of the wooden blocks 3 to form the upper roadbed 2.

This fastening means is, for example, by melting the fastener 9 on the right end of the binding material 8 and attaching the other end of the binding material 8 to each of the wooden blocks 3 arranged in parallel.
The wood blocks 3 are sequentially inserted through the through holes 4 and a predetermined tensile force is applied to press each wooden block 3 to each other, and a similar clasp 9 is welded to the other end while maintaining this state. .

Therefore, the clasp 9 at the face end of the binding material 8 is located at the open end of the through hole 4 of the wooden block 3 and is accommodated in the U-shaped groove 5, and as described above, each wooden block 3 is attached to the binding material 8. The clasps 9 do not protrude from the end surface of the upper roadbed 2 configured by being fixed through the upper roadbed, and the latches 9 do not get in the way when a plurality of upper roadbeds 2 are arranged side by side.

As mentioned above, since the U-shaped groove 5 only accommodates the end portions of the clasp 9 and the binding material 8, it is not necessary to provide the U-shaped groove 5 all around the wooden block 3, and the clasp 9 It may be a simple concave shape as long as it can be positioned so as not to protrude outward from the side surface. Further, the U-shaped groove 5 only needs to be formed in the wooden block 3 located at the end of the upper roadbed 2. However, in reality, when manufacturing the wooden block 3, it is more efficient to mold the same object in the same process during manufacturing and assembly.

Further, since the binding material 8 is inserted in a cross shape in the length and breadth of the wooden block 3, the two through holes 4 are prevented from communicating with each other.

Next, the lower roadbed 10 that supports the lower part of the upper roadbed 2 is made of concrete, and is provided with insertion holes 11 into which the insertion portions 7, which are the lower parts of the wooden blocks 3 described above, are individually inserted. The hole 11 has a shape corresponding to a log or square lumber that is the shape of the wooden block 3, and a partition wall 12 is formed between adjacent fitting holes 11, and reinforcing bars 13 are arranged vertically and horizontally throughout the entire structure including the partition wall 12. .

In addition, a drainage hole 14 is provided in the vertical direction at the bottom of each insertion hole 11, and a drainage groove 15 is carved toward the drainage hole 14, and hooks 16 made of, for example, a steel layer are provided at the corners of the lower roadbed 10. To protrude.

Therefore, by individually fitting the insertion portions 7 of the wooden blocks 3 of the upper roadbed 2 into the insertion holes 11 of the lower roadbed 10, the upper roadbed 2 and the lower roadbed 10 are integrated and constitute the roadbed material 1.

In the upper roadbed 2, the binding material 8 is inserted vertically and horizontally into each wooden block 3, and is securely fixed by the clasp 9, and the fitting part 7 is fitted into the fitting hole 11, so that each wooden block 3
They do not shift relative to each other and can be handled as a single piece of roadbed material, which is extremely convenient when transporting or laying.

The road base material 1 of the present invention is constructed by leveling the road base on an existing asphalt road surface and laying it on top of it, and this construction may cause inconveniences if the road surface becomes substantially higher, or if there are other circumstances. In some cases, only the asphalt may be peeled off, crushed stone and sand may be leveled, and the asphalt may be laid on top of it.

In this case, only the lower roadbed 10 is laid on the road surface in advance, but at this time, the lower roadbeds 10 are connected to each other via the above-mentioned hooks 16, and after the connection, concrete is poured into the gap. become.

In addition, since the upper roadbed 2 is made of wood, powders such as asphalt and crushed stone are not generated when the vehicle runs.
Even if chains and spiked tires are used, the amount of wear on the chains and spiked tires is extremely small, so there is no risk of iron powder turning into dust.

Since it is made of wood, it is inevitable that it will reach the end of its lifespan after being used for a certain amount of time, but in this case as well, all that is required is to remove the upper roadbed 2 from the lower roadbed 10 and replace it, which is an extremely simple process. Therefore, the upper roadbed 2
Since it is supported by the lower roadbed 10, it is hard to be damaged and can ensure sufficient strength. In particular, reinforcing bars 13 are also placed in the partition wall 12 portion of the lower roadbed 10, which is considered to be directly affected by the weight of the vehicle applied to the upper roadbed 2, so that the strength of the lower roadbed 10 itself is ensured.

Furthermore, when each wooden block 3 is assembled as the upper roadbed 2, the log-shaped wooden blocks 3 can form a gap 6a in the vertical direction between the adjacent wooden blocks 3, which prevents rain and snow from falling. Since the water can be quickly drained from the gap 6a, no puddles are formed, and passers-by are not splashed with muddy water. This gap 6a can be formed by the above-mentioned notch 6 when the wooden block 3 is a square lumber.

The water drained from this gap 6a is then drained from the lower roadbed 1.
Since the water flows from the insertion hole 11 of No. 0 through the drainage ditch 15 to the drainage hole 14 and is disposed of underground, there is no possibility that it will stagnate and cause problems such as corrosion of the wooden blocks 3 and the lower roadbed 10. do not have.

The road base material 1 of the present invention is preferably installed in urban areas where the influence of dust or noise is particularly large, but it is not only used for roadways, but can also be used for sidewalks. Since it is necessary to take measures to prevent the heel of the shoe from entering the gap 6a, specifically, this gap 6a must be made extremely small.

8 and 9 show another embodiment of the present invention, and the road base material 1 in this embodiment has wooden blocks 3 arranged side by side in the front-rear and left-right directions and secured with binding materials 8. A thick plate-shaped lower roadbed 10 made of reinforced concrete is superimposed on the lower surface of the upper roadbed 2. In order to form a road surface using the road base material 1 constructed in this way, a vertical through hole 10a that coincides with the gap 6a of the upper road base 2 is opened in the lower base base 10, When the road base material 1 is placed in a laid manner, the continuous gap 6a and the through hole 1 are formed.
Pass the fastening material 17 such as a nail from above through the fastening material 17.
Drive the lower part of the into the foundation ground.

Therefore, the upper roadbed 2 and the lower roadbed 10 are integrated with each other by the fastening material 17, and can form an effective road surface.

Note that in the embodiments shown in FIGS. 8 and 9, unexplained symbols have the same configuration as the same symbols in the previous embodiments, so the explanation will be omitted.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and can be implemented in any manner as long as the configuration described in the claims is not changed.

<Effects of the Invention> In summary, according to the present invention, since the upper roadbed is made of wood, no dust is generated even when vehicles frequently run, and it has a sound absorption effect, so it is possible to prevent noise. Not only is it easy to process and manufacture, it is also easy to transport and install, and the material costs are low.Also, since the upper roadbed is supported by the lower concrete roadbed, it is difficult to damage and has sufficient strength. It has many excellent effects, such as the ability to
