BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow melting apparatus used for carports and roads in cold regions.

[0002]

2. Description of the Related Art In recent years, roads have become an artery of industry and daily life due to the development of motorization, and even in cold regions, it is no longer possible to delay the removal of snow from roads during snowfall by one day. .

Further, in a garage such as a carport at a guest house or an inn in a cold region, or in a private road, it is necessary to remove snow at the time of snowfall in order to secure entry and exit of cars. Snow melting methods are increasingly used.

Conventionally, as such a heating method, a hot water circulation type and an electric heater type are known.
Since the running cost can be reduced, a hot water circulation system is often used.

As such a hot-water circulation type snow melting apparatus, for example, as shown in FIG. 6, a crushed stone layer 22 for leveling is formed on an installation surface 21, and then a welding wire mesh is formed on the crushed stone layer 22. After laying (4 mmφ) 23, a water pipe 24 made of a vinyl chloride resin or the like is formed, for example, so as to have the arrangement shown in FIG. Next, a concrete layer is formed by casting concrete so as to cover each of the crushed stone layers 22, the welding wire mesh 23 and the water pipe 24 with a predetermined thickness.

In such a snow melting apparatus, a car or the like can be put on the concrete layer 25, and the concrete layer 25 is heated by passing hot water through the water pipe 24 so that the concrete layer 25 is heated. It is possible to melt and remove snow that has accumulated on the vehicle, and to secure entry and exit of the vehicle and the like.

[0007]

However, in the above-mentioned conventional snow melting apparatus, it takes time to form the water pipe 24 so as to have a predetermined arrangement, and it takes time to cure the concrete. There is a problem that the length is increased and the cost is increased.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a snow melting apparatus in which a plurality of foam molded plates having pipe grooves are connected to the pipe grooves on an installation surface. A flexible water flow pipe is laid in each of the communicating pipe grooves, and a concrete plate is laid on each of the foam molded plates.

[0009]

According to the above construction, a lightweight foam molded plate is laid, and then a water pipe is piped in a piping groove of the foam molded plate. By laying the prepared concrete plate on the foam molded plate, for example, a car or the like can be placed on the concrete plate.

[0010] Further, in the above configuration, the concrete plate can be heated by flowing hot water or the like through the water pipe, so that snow accumulated on the concrete plate can be melted and removed. It is.

[0011] In addition, the above-mentioned configuration is such that, for example, if the pipe groove is formed on the upper surface of the foam molded plate, the water flow pipe faces the concrete plate, and is located in the direction from the water pipe due to the heat insulating effect of the foam molded plate. By reducing the transmission of heat downward, heat from the water pipe can be efficiently transmitted to the concrete plate, and snow on the concrete plate can be efficiently melted.

[0012] Further, the above-mentioned structure can mass-produce the above-mentioned foam-molded plate and concrete plate in a factory, for example, and can pre-mold them, so that the conventional concrete curing period can be omitted. It is also possible to provide a foam molded plate, a water pipe, and a concrete plate in this order, and it is possible to shorten the construction time as compared with the related art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In the snow melting apparatus, as shown in FIG. 1, a crushed stone layer 2 is laid on an installation surface 1 with a thickness of, for example, about 100 mm, and the surface is leveled substantially horizontally. A mortar layer 3 made of kneaded mortar is provided on the crushed stone layer 2. The above-mentioned kneaded mortar is obtained by adding no water to a mixture of portland cement and sand, and the mixing ratio is, for example, portland cement: sand = 1: 3.

The upper surface of the mortar layer 3 is substantially horizontal, but is formed so that the height gradually decreases toward a drain port (not shown).
Since the Portland cement absorbs moisture and the like in the air over time and hardens, the water that has entered the mortar layer 3 can be drained toward the above-mentioned drain port, and the mortar layer of the entered water can be discharged. 3 can be prevented from staying.

On the mortar layer 3, a foam molded plate 4
However, a plurality of them are laid closely adjacent to each other and densely, and their upper surfaces are flush with each other. The material of the foam molded plate 4 is not particularly limited as long as it is lightweight and has a compressive strength not less than a predetermined value. For example, foamed polystyrene (trade name: Eslenfoam, company name: Sekisui Plastics Co., Ltd., (10-60 times magnification), expanded polyethylene (5-20 times expansion ratio), or styrene-modified expanded polyethylene (trade name: PIOCELAN, company name: Sekisui Chemical Co., Ltd., expansion ratio 10-40 times) Can also be
For example, the compression strength of the above-mentioned molded article of expanded polystyrene having an expansion ratio of 30 is 16 tons / m ² .

On the upper surface side of the foam molding plate 4, a piping groove 6 for piping a water pipe 5 described later into the foam molding plate 4 is formed. Two types are formed on the plate 4 in order to communicate the respective piping grooves 6.

That is, as shown in FIG. 2, the main foam molded plate 4a, which is one foam molded plate 4, is, for example, 600 × 600.
Each of the main pipe grooves 6a is formed in parallel with each other and is formed into a shape having a thickness of 30 mm and a thickness of 30 mm.

In addition, each of the main pipe grooves 6a is parallel to one side of the main foam molded plate 4a, and is 75 mm from the above side in the above-described example of dimension, and is a distance between adjacent main pipe grooves 6a. Is formed to be 150 mm. The shape of each of the main pipe grooves 6a is such that a water pipe 5 described later can be fitted therein. For example, when the diameter of the water pipe 5 is 17 mm, the foam molded plate 4 has elasticity. From the above, the width and depth of the main pipe groove 6a are 16
mm.

As shown in FIG. 3, for example, a 300.times.300
A pair of communicating pipe grooves 6 formed in each dimension of 30 mm in thickness and 30 mm in thickness and curved from one side to two adjacent sides.
b is formed facing backward, and each of the communication pipe grooves 6b
The opening on one side extends about 75 mm in parallel with the two sides from a position of 75 mm from both ends of the one side, and further, is curved from its tip to form a quarter circle of R75 mm. Each is formed.

As shown in FIG. 4, for example, each of the main foam molded plates 4a and the communicating foam molded plates 4b are first so that the two main foam molded plates 4a communicate with the respective pipe grooves 6a. A plurality of predetermined sets of the main foam molded plates 4a communicating with the respective pipe grooves 6a are laid so that the respective pipe grooves 6a are parallel to each other.

Next, each of the communicating foam molded plates 4a is connected so that the adjacent main piping groove 6a of each of the main foam molded plates 4a is communicated with each of the communicating piping grooves 6b of each communicating foam molded plate 4b. 4b is laid. The order of laying the foam molded plates 4 is not limited to the above, and may be reversed.

Subsequently, as shown in FIG. 1, a flexible water pipe 5 made of, for example, a crosslinked polyethylene resin and having a flexible water pipe 5 (trade name:
Eslopex, company name: Sekisui Chemical Co., Ltd.). Such a water pipe 5 is formed so as to fit into the pipe groove 6. In the example of the dimensions of the pipe groove 6, for example, the outer diameter is formed to be 17 mm.

Thereafter, a concrete plate 7 having a size of, for example, 600 × 600 mm and a thickness of 40 mm is laid on each of the foam molded plates 4. By the way, the construction time of the snow melting apparatus as described above is, for example, the size of a carport having the size of one car, that is, when constructed on the installation surface 1 having a length of 4.8 m and a width of 2.4 m, Since the formation of the crushed stone layer 2 and the mortar layer 3 is of a dry type, and the foam molded plate 4 and the concrete plate 7 can be easily transported and laid by a single worker, about 2
Completed in time.

As shown in FIG. 5 (a), the surface of each concrete plate 7 has a predetermined pattern as shown in FIG. A groove 7a is formed. The pattern on the surface of the concrete plate 7 is not limited to the above, and the groove-shaped portion 7a may be formed in a pattern shown in FIGS. 5B to 5D, for example.

As described above, according to the configuration of the above-described embodiment, each of the lightweight foam-molded plates 4 is laid, and then the water pipe 5 is piped, and then, for example, formed into a size and weight that can be carried by a person. if laid concrete plate 7 on the foam molding plate 4, because the compressive strength of the foam molding plates 4 above is 16 t / m ^2, on the concrete slab 7, for example, the vehicle weight 1-2
A ton car or the like can be mounted with sufficient margin.

In addition, the above configuration allows the concrete plate 7 to be heated by passing warm water heated with antifreeze through the water pipe 5 facing the concrete plate 7. Due to the heat insulation effect of the above, the downward transmission of heat from the water pipe 5 is blocked, so that the above-mentioned heat can be efficiently transmitted to the concrete plate 7 and the snow accumulated on the concrete plate 7 can be efficiently removed. It can be removed by melting snow.

Since the above uses antifreeze,
Even without circulating in the water pipe 5, breakage of the water pipe 5 due to freezing is avoided, and frost heaving of the installation surface 1 can be prevented by the heat insulating effect of the foam molded plate 4.

In addition, the above-mentioned construction is the same as that of the above-mentioned foam molded plate 4.
For example, since the concrete plate 7 can be mass-produced in a factory and can be formed in advance, it is possible to omit the conventional curing period of the concrete and the attachment of the water pipe to the welding wire mesh.

Further, the above-mentioned structure allows the mortar layer 3 to be formed in a dry manner, thereby speeding up and simplifying the process of forming the mortar layer 3. Further, the foam molding plate 4 and the concrete plate 7 can be formed by one person. Workers can easily carry and lay the pipe, and the flexibility of the water pipe 5 saves the labor of pre-forming the water pipe 5 into a predetermined shape as in the related art.

[0030] From the above, the above-described configuration can greatly reduce the construction time compared to the conventional one, and further, can simplify the construction operation more than before, so that labor costs and the like can be reduced and the cost can be significantly reduced. Can be.

In the structure of the above embodiment, an example in which a synthetic resin is used as the material of the foam molded plate 4 has been described. However, if it is lightweight and has a predetermined compressive strength, it is formed by foaming an inorganic material, for example. Foamed concrete boards and the like can also be used.

[0032]

As described above, in the snow melting apparatus of the present invention, a plurality of foam molded plates having pipe grooves formed thereon are laid on the installation surface so as to communicate with the pipe grooves, respectively. A water pipe is provided in each pipe groove, and a concrete plate is laid on each foam molded plate.
