 In recent years, roads have become the arteries of industry and daily life due to the development of motorization, and even in cold regions, it has become impossible to delay snow removal on roads for a day.

In a garage such as a carport at a guesthouse or inn in a cold region or a private road, it is necessary to remove snow during snowfall in order to ensure entry and exit of cars, and in order to save such trouble of snow removal. The snow melting method by heating has been widely used.

Conventionally, as such a heating method, a hot water circulation type and an electric heater type are known, but the hot water circulation type is widely adopted because the running cost can be reduced.

In such a warm 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 subsequently, a crushed stone layer 22 is welded. After laying the wire mesh (4 mmφ) 23, a water pipe 24 made of vinyl chloride resin or the like is molded so as to have the arrangement shown in FIG. 7, for example, and is fixed to the welded wire mesh 23 with a binding wire (not shown). Next, a concrete layer 25 is formed by pouring concrete so as to cover each of the crushed stone layers 22, the welded wire net 23 and the water pipe 24 with a predetermined thickness.

In such a snow melting device, a car or the like can be placed on the concrete layer 25, and by passing hot water through the water pipe 24, the concrete layer 25 is heated and the concrete layer 25 is heated. The snow on the top can be melted and removed, and the entry and exit of the above-mentioned cars can be secured.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. In the snow melting device, as shown in FIG. 1, a crushed stone layer 2 is laid on the installation surface 1 with a thickness of, for example, about 100 mm, and the surface is leveled almost horizontally. On the crushed stone layer 2, a mortar layer 3 made of dry kneaded mortar is provided. It should be noted that the above-mentioned dry kneaded mortar is one in which water is not added to the mixture of Portland cement and sand, and the mixing ratio is, for example, Portland cement: sand = 1: 3.

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

On the mortar layer 3, a plurality of foam molding plates 4 are laid adjacently to each other and densely so that their upper surfaces are flush with each other. The material of the foamed molded plate 4 is not particularly limited as long as it is lightweight and has a compressive strength higher than a predetermined value. 10 to 60 times), expanded polyethylene (5 to 20 times expansion ratio), or styrene modified expanded polyethylene (trade name: PIOCELAN, company name: Sekisui Plastics Co., Ltd., expansion ratio 10 to 40 times). It can be used and, for example, the compression strength of a molded product of the above expanded polystyrene having a foaming ratio of 30 times is 16 tons / m ² .

On the upper surface side of the foam-molded plate 4, there is formed a pipe groove 6 for connecting a water pipe 5 described later in the foam-molded plate 4, and such a foam-molded plate is also formed. Two types are formed on the plate 4 in order to connect the pipe grooves 6 to each other.

That is, as shown in FIG. 2, the main foam-molded plate 4a, which is one of the foam-molded plates 4, is molded into each dimension of, for example, 600 × 600 mm and a thickness of 30 mm, and has four linear shapes. The main pipe grooves 6a are formed in parallel with each other.

Moreover, each of the main piping grooves 6a is parallel to one side of the main foam molding plate 4a, and is 75 mm from the side in the above dimension example, and the distance between the adjacent main piping grooves 6a. Is formed to be 150 mm. The shape of each main pipe groove 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 molding plate 4 has elasticity. Therefore, the main piping groove 6a is formed so that the width and the depth thereof are 16 mm.

Further, as shown in FIG. 3, the communication foam-molded plate 4b which is the other foam-molded plate 4 is molded into each dimension of, for example, 300 × 300 mm and a thickness of 30 mm, and is adjacent from one side. A pair of communication piping grooves 6b, which are curved to reach two sides, are formed on the back, and each communication piping groove 6b has an opening on the one side of 75 mm from each end of the one side. From the position of about 75 mm in parallel with the above-mentioned two sides, and further, they are formed by being bent from their tips to have a quarter circle shape of R75 mm.

Each of the main foam molded plates 4a and the communication foam molded plate 4b is, for example, as shown in FIG. 4, first, the two main foam molded plates 4a communicate with the respective pipe grooves 6a, and The main foamed molded plates 4a communicating with the respective pipe grooves 6a are laid in a plurality of predetermined groups, and the respective pipe grooves 6a are laid so as to be parallel to each other.

Next, each main foam molding plate 4a has its adjacent main piping groove 6a communicated with each other by the communication piping groove 6b of each communication foam molding plate 4b. 4b is laid. The laying order of the foam-molded plates 4 is not limited to the above, and may be reversed.

Subsequently, as shown in FIG. 1, in the pipe groove 6 including the above-mentioned pipe grooves 6a and 6b, for example, a flexible water pipe 5 (trade name: Eslopex, made of cross-linked polyethylene resin, Company name: Sekisui Chemical Co., Ltd.) Such a water pipe 5 is shaped to fit into the above-mentioned pipe groove 6, and in the example of the size of the above-mentioned pipe groove 6, for example, the outer diameter is formed to 17 mm.

After that, a concrete plate 7 having a size of, for example, 600 × 600 mm and a thickness of 40 mm is laid on each foam-molded plate 4 described above. By the way, the construction time of the above-mentioned snow melting equipment is, for example, when the construction is carried out on the installation surface 1 having the width of a carport having the width of one car, that is, the length of 4.8 m and the width of 2.4 m. The formation of the crushed stone layer 2 and the mortar layer 3 is a dry process, and the foamed molding plate 4 and the concrete plate 7 can be easily transported and laid by one worker, so that it was completed in about 2 hours.

The surface of each concrete board 7 has a predetermined pattern on the surface of the concrete board 7 as shown in FIG. 5 (a) in order to improve slip prevention, aesthetics, and drainage. A groove portion 7a is formed. Further, the pattern of the surface of the concrete board 7 is not limited to the above, and the groove portions 7a may be formed in the patterns shown in FIGS. 5 (b) to 5 (d), for example.

As described above, according to the configuration of the above-mentioned embodiment, after laying each of the lightweight foam molding plates 4 and then piping the water passage pipe 5, the foam molding plates 4 are molded to have a size and weight that can be carried by a person, for example. If a concrete board 7 is laid on the foam-molded board 4, the compressive strength of each foam-molded board 4 is 16 tons / m ² , so that, for example, a vehicle weight of 1 to 2 tons is placed on the concrete board 7. It is possible to mount a car, etc. with sufficient margin.

Further, in the above configuration, the concrete plate 7 can be heated by passing hot water obtained by heating the antifreezing liquid through the water pipe 5 facing the concrete plate 7. Due to the heat insulation effect of No. 4, the heat from the water pipe 5 is blocked from being transmitted downward, so that the above heat can be efficiently transmitted to the concrete plate 7, and the snow accumulated on the concrete plate 7 can be removed. It is possible to efficiently melt and remove snow.

Since the antifreeze liquid is used in the above, damage to the water passage pipe 5 due to freezing can be avoided without circulating the water passage pipe 5 and the heat insulation effect of the foam molding plate 4 prevents the installation surface 1 from freezing. Can also be prevented.

In addition, since the foam molding plate 4 and the concrete plate 7 can be mass-produced in a factory and pre-molded in the above-described configuration, the conventional concrete curing period or It is possible to omit the installation of the water pipe to the welded wire mesh.

In addition, the above-mentioned constitution makes it possible to form the mortar layer 3 by a dry method, speeding up and simplifying the step of forming the mortar layer 3, and further, forming the foam molding plate 4 and the concrete plate 7 by one person. The operator can easily carry and lay it, and the flexibility of the water pipe 5 saves the labor of previously forming the water pipe 5 into a predetermined shape as in the conventional case.

From the above, the above-mentioned configuration can significantly reduce the construction time compared with the conventional construction, and moreover, the construction operation can be simplified compared with the conventional construction, so that the labor cost can be reduced and the cost can be largely reduced. You can

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