[Detailed description of the device]

[Industrial applications]

 The present invention relates to a snow melting structure for roads, parking lots, etc., and more particularly to an improvement of a snow melting structure in which a heater is embedded under the concrete paving layer for concrete paved roads, parking lots, etc. ..

[0002]

[Prior art and its problems]

 Conventionally, as the snow melting structure of this type, the structures shown in FIGS. 3 and 4 and the structures shown in FIGS. 5 and 6 are known. However, since the former snow melting structure shown in FIGS. 3 and 4 has a structure in which the heat insulating material 10 is laid on the roadbed 4 so that the outer peripheral edges thereof are brought into contact with each other and adjacent to each other, There is no support structure for supporting the heat insulating material 10 between the heater pipe 9 in which the reinforcing bars 8 are arranged above and below the concrete pavement layer 7 in the thickness direction (height direction). Therefore, the heat-insulating layer causes a bending deformation as shown in the figure due to the load of the vehicle 11 traveling on the surface of the pavement layer 7, the so-called road surface 7a, which causes cracks on the road surface 7a, which is troublesome to repair. In addition to the cost, the repair cost is enormous and there is a danger that the embedded heater tube will burst. On the other hand, in the case of the latter snow melting structure shown in FIGS. 5 and 6, when the heat insulating material 10 is arranged on the roadbed 4, the heat insulating material 10 is spread over the outer peripheral edges of the heat insulating material 10 so that the heat insulating material 10 can be spread over the heat insulating material 10. A concrete pouring gap 12 is secured between them, and fresh concrete is poured into the gap 12 to support the concrete pavement layer 7 on the roadbed 4 on the outer periphery of the heat insulating material 10. Although such problems can be solved a little, the work of laying the heat insulating material 10 should be carried out because it is a construction method in which the heat insulating material 10 is spread on the roadbed 4 as a guide and the concrete pouring gap 12 is formed between the heat insulating materials 10. There was a problem in terms of workability, such as the amount of fresh concrete used could not be calculated because it was troublesome and there were variations in the intervals of the concrete pouring gap 12.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of such conventional circumstances, and the technical problem to be solved is that the laying of a heat insulating material is easy, the amount of fresh concrete used can be calculated, and the bending of the heat insulating material can be calculated. It is an object of the present invention to provide a snow melting structure capable of reliably preventing deformation and the like.

[0004]

[Means for achieving the object]

 To achieve the above-mentioned object, the technical means taken by the present invention is to form a square shape having an appropriate thickness, and to form and arrange a concrete pouring hole of an appropriate shape that penetrates from the upper surface to the back surface and to form the outer peripheral edge thereof. In addition, a heat insulating material having the hole forming concave portion is spread between the roadbed and the heater.

[0005]

[Action]

 Thus, according to the above-mentioned technical means of the present invention, the outer peripheral edges are placed adjacent to each other and the heat insulating material is laid on the roadbed so as to be adjacent to each other. Concrete pavement is carried out by pouring concrete onto the heat insulating material. As a result, in the concrete pouring hole that escapes from the upper surface of the heat insulating material toward the back surface, that is, the upper surface of the roadbed, as well as in the concrete pouring hole that is formed by matching the hole forming recesses between the outer peripheral edges of the adjacent heat insulating materials. The solidified portion of the ready-mixed concrete that flows into the building acts as a pillar that supports the concrete pavement layer on the roadbed, and prevents the heat insulating material from bending and deforming.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The heat insulating material 1 is made of a material such as a foam urethane and has a rectangular shape having an appropriate thickness and size according to the application, and in the drawing is a substantially rectangular shape. In addition, a concrete casting hole 2 having an appropriate shape penetrating from the upper surface to the rear surface is formed and arranged, and the hole forming recessed portion 3 is formed on the outer peripheral edge thereof. From the upper surface to the rear surface, that is, the upper surface of the roadbed 4. The concrete concrete that flows into the concrete pouring hole 5 that is formed by the mutual matching (matching match) between the hole forming recesses 3 between the outer peripheral edges of the adjacent heat insulating materials 1 and the concrete 2 The solidification part 6 of the above acts as a pillar that supports the concrete pavement layer 7 on the roadbed 4, and prevents the heat insulating material 1 from bending and deforming due to the load of the vehicle 11 traveling on the surface of the pavement layer 7, the so-called road surface 7a. Use a heat material protection structure.

As shown in the figure, the concrete pouring holes 2 are formed in an appropriate shape such as a corner or a round shape, and a plurality of holes are formed so as to line up in a longitudinal direction of the heat insulating material 1 that penetrates from the upper surface to the back surface of the heat insulating material. The constitutional recessed portion 3 constitutes half or a part of the opening shape of the hole 2 and has a recessed shape and fits with each outer peripheral edge of the heat insulating material 1 adjacent in four directions. In each peripheral edge drawing including the four corners of No. 1 as shown in FIG. 1, the short edge is provided with a recess, and as shown in FIG. 1, the hole forming recesses 3 are fitted between the short edges of the adjacent heat insulating materials 1. The concrete pouring hole 5 is constituted by the above.

Then, the heat insulating material 1 is laid on the roadbed 4 so that the outer peripheral edges thereof are brought into contact with each other so as to be adjacent to each other, and thereafter, the heater pipe 9 having the reinforcing bars 8 arranged above and below is piped. Concrete pavement is performed by pouring green concrete onto the heat insulating material 1. Then, in the pre-designed cross-sectional area, that is, the inflow volume of the fresh concrete, from the upper surface of the heat insulating material 1 to the back surface thereof, that is, the upper surface of the roadbed 4, the inside of the concrete pouring hole 2 and adjacent heat insulating materials 1 The solidified portion 6 of the ready-mixed concrete that has flown into the concrete pouring hole 5 formed by the mutual fitting of the hole forming concave portions 3 between the short side edges acts as a pillar that supports the concrete pavement layer 7 on the roadbed 4. By the support of each solidifying portion 6, it is possible to reliably prevent the heat insulating material 1 from bending and deforming due to the load of the vehicle 11 or the like (see FIG. 2).

[Effect of the device]

 The snow melting structure of the present invention, such as a road and a parking lot, has a hole construction between the outer peripheral edges of the adjacent heat insulating materials inside the concrete pouring holes provided from the upper surface to the rear surface, that is, the upper surface of the roadbed as described above. Fresh concrete is poured into the concrete pouring hole that is configured by the mutual fitting of the recesses, and the concrete pavement layer is supported by the solidified portion of the poured fresh concrete. It is possible to reliably prevent bending deformation of the heat material. Moreover, since the concrete pavement layer is supported by pouring fresh concrete into the concrete pouring hole with a pre-designed cross-sectional area, the amount of fresh concrete used during concrete pavement can be calculated, and the conventional method is used. There is no problem in workability when laying the heat insulating material on the roadbed and workability due to the amount of fresh concrete used. Therefore, according to the snow melting structure for roads, parking lots, etc. of the present invention, it is easy to lay a heat insulating material, the amount of green concrete used can be calculated, and the bending deformation of the heat insulating material can be reliably prevented. .
