Description

  The present invention relates to a snow melting panel.

  The snow-melting panel is laid on the entrance of a house, a storefront, a garage entrance, a garden, a parking space, approach to these places, or a general road, and is used to efficiently melt snow that contacts the surface. For example, Patent Document 1 discloses one using a cement concrete flat plate in which a pipe for circulating hot water is embedded. However, since the hot water passes through the pipe, the heat is transferred to the surface through the pipe wall forming the pipe and further through the cement concrete in which the pipe is embedded. . Therefore, heat transfer efficiency is poor and there is a problem in terms of snow melting efficiency. In view of this point, in Patent Document 2, a bottom plate, a lower snow melting plate portion provided with front and rear walls and left and right walls rising from the periphery of the bottom plate, and an upper portion continuously provided on the upper surface of the lower snow melting plate portion The thing which consists of a snow-melting board part is disclosed. A partition wall having holes through which water passes is provided at the front and rear ends in the lower snow melting plate portion, and hot water flowing in from the inlet passes through the grooves between the partition walls and sequentially passes through adjacent holes through the holes at the front and rear ends. It is the structure guided to the outlet and the outlet.

  According to the technique disclosed in Patent Document 2, since warm water passes between a lower snow melting plate portion and an upper snow melting plate portion made of a casting, heat is easily transmitted to the outside through both. Therefore, compared with the technique disclosed in Patent Document 1, it is considered that heat transfer efficiency and snow melting efficiency are superior. However, this type of snow melting panel is used by being laid at each of the above-mentioned locations, and usually snow accumulates on the upper snow melting plate portion. Therefore, it is important that the heat conductivity of the upper snow melting plate is high, but if the heat conductivity of the lower snow melting plate is high, the hot water circulated through the lower snow melting plate is easy to cool, so that it is supplied from a heat source such as a boiler. There is a room for improvement in terms of energy efficiency. Moreover, since it is formed from a casting, the manufacturing cost tends to be high, and there is a predetermined weight, so that the installation work is troublesome and the work cost is high.

  The present invention has been made in view of the above points. Compared to the conventional art, a snow melting fluid such as warm water is less likely to be cooled, has excellent energy utilization efficiency, can be manufactured at low cost, and is light in weight. It is an object of the present invention to provide a snow melting panel that contributes to facilitation and reduction in work cost.

  In order to solve the above-mentioned problems, a snow melting panel of the present invention comprises a surface layer, a back surface layer, a base member having a cavity provided between the surface layer and the back surface layer, one end flowing into the inlet, and the other end flowing into the inlet. A fluid pipe that serves as an outlet and circulates a snow melting fluid piped to have a meandering shape in plan view on the surface layer of the base member; and the fluid pipe on the surface layer of the base member An intermediate layer member made of a heat insulating material disposed so as to surround the surface, and a surface which is laminated on the fluid pipe and the intermediate layer member, and which is a contact surface with snow through the fluid pipe for heat of the snow melting fluid And a supporting member that integrally supports the base member, the fluid piping, the intermediate layer member, and the covering member.

It is preferable that the base member is made of a synthetic resin having a high heat insulating property, and it is preferable that the base member is a plastic cardboard.
The support member has a substantially U-shaped cross section, each flange portion is laminated on the lower surface of the base member and the upper surface of the covering member, and a connecting portion connecting the flange portions is the base member, the intermediate layer member, and the covering An end wall member disposed so as to cover the peripheral surface of the member, and a connecting member that penetrates from the base member to the covering member in the stacking direction and connects the flange portions of the end wall member. It is preferable that
It is preferable that a connecting member that integrally connects the base member to the covering member is further provided at a position adjacent to the fluid pipe.

  According to the present invention, the fluid piping through which the snow melting fluid flows is supported on the surface layer of the base member having the cavity. Since this hollow portion functions to make it difficult to conduct cold heat from the ground, it is difficult to cool a snow melting fluid such as hot water. As such a base member, it is preferable that the base member is made of a synthetic resin having a high heat insulating property, and it is preferable to use a plastic cardboard. In addition to being available at a low cost, it is very lightweight and contributes to the transportation of the snow melting panel of the present invention, the ease of installation work, the production cost, and the reduction in work cost. In addition, since the fluid piping is surrounded by an intermediate layer member made of a heat insulating material, the snow melting fluid is difficult to cool at that point, and the covering member is made of metal, so that heat can be quickly transferred to the surface of the covering member, The snow melting efficiency with respect to the snow on the covering member is excellent. Further, by integrating the base member, the fluid piping, the intermediate layer member, and the covering member using the support member, the snow melting panel of the present invention can be handled as one unit, and is easy to transport and install. Further, it is preferable to further provide a connecting member for connecting the base member to the covering member in the stacking direction at a position adjacent to the fluid piping, thereby causing distortion of the covering member due to the weight of snow, the influence of heat, etc. In this case, the separation between the covering member and the fluid piping is suppressed, which helps to prevent the heat conduction function from being lowered.

FIG. 1 is a perspective view showing an appearance of a snow melting panel according to an embodiment of the present invention. FIG. 2 is a sectional view taken along the line AA in FIG. FIG. 3 is a diagram for explaining an example of the layout of the fluid piping. FIG. 4 is a diagram for explaining another example of the layout of the fluid piping.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1-4 is a figure for demonstrating the snow melting panel 1 which concerns on this embodiment, and as shown in these figures, the snow melting panel 1 of this embodiment is the base member 10, the fluid piping 20, The intermediate layer member 30, the covering member 40, the support member 50, and the like are configured.

  As shown in FIG. 2, the base member 10 includes a surface layer 11, a back surface layer 12, and a cavity portion 13 provided between the surface layer 11 and the back surface layer 12. Since the cavity portion 13 is provided, air can be retained in the inside thereof, thereby making it difficult to conduct cold heat from the ground. The base member 10 is preferably formed from a synthetic resin having a high heat insulating property in order to enhance the cold heat blocking function. Typically, it is preferable to use plastic corrugated cardboard formed from polypropylene or the like. The plastic corrugated cardboard is provided with a rib 14 between the front surface layer 11 and the back surface layer 12, and a cavity 13 is formed between the adjacent ribs 14 and 14, and is inexpensive as the base member 10 used in this embodiment. And can be easily processed into a predetermined size and shape. In addition, since the base member 10 is directly installed on the ground or the like, each end opening in the longitudinal direction of the cavity portion 13 is provided with a water stop treatment, for example, an end surface opening so that water does not enter the cavity portion 13. It is preferable to load the plug member or to melt and seal the vicinity of the end opening.

  The fluid pipe 20 is made of a metal pipe material such as aluminum, and is piped on the surface layer 11 of the base member 10. The fluid pipe 20 has a structure in which one end is an inflow port 21 and the other end is an outflow port 22, and the snow melting fluid flows from the inflow port 21 toward the outflow port 22. Although the cross-sectional shape is not limited, as shown in FIG. 2, a substantially square shape is preferable to a substantially circular shape because the contact area with the covering member 40 becomes larger. In addition, piping is provided on the surface layer 11 so as to meander in a plan view so that the contact area with the covering member 40 becomes larger. In the present embodiment, a plurality of straight line portions 23 are piped at a predetermined interval between the inflow port 21 and the outflow port 22, and one end portions or the other end portions of the adjacent straight line portions 23 are alternately arranged. It is made into the shape provided with the several folding | turning part 24 which consists of a substantially semi-circular rounded part to connect.

  Specifically, as shown in FIG. 3, a straight portion 23 is provided in the depth direction from the inlet 21, and then a folded portion 24 formed of a rounded portion is provided at the end on the back side, and reaches the near side as it is. In addition, a straight portion 23 is provided, and a folded portion 24 made of a rounded portion is provided at the end on the near side, and this is repeated several times, and the last straight portion 23 is laid so as to reach the near side. Then, it extends in the direction of the inflow port 21 along the edge 1a on the near side of the snow melting panel 1 and is bent outward at a position before contacting the inflow port 21 to provide the outflow port 22.

  However, the pipe shape in plan view of the fluid pipe 20 is not limited to the one shown in FIG. 3 as long as it is a meandering shape. For example, as shown in FIG. It can be set as the shape which connected the one end parts of the part 23, or the other end parts. Further, as shown in FIG. 4, if the inlet 21 is positioned near one side 1b of the edge 1a on the near side of the snow melting panel 1, the outlet 22 is positioned near the other side 1c. You may pipe as you do. Further, it may be a spiral shape or the like in plan view, and it is included in the meandering shape in the present invention as long as it is a combination of a straight line portion and a curved portion and has a predetermined spread in the plane direction. This is appropriately determined in consideration of the size of the snow melting panel 1, ease of processing, and the like.

  The intermediate layer member 30 is disposed so as to surround the fluid pipe 20. Specifically, as shown in FIGS. 2 and 3, the surface layer 11 of the base member 10 is spread over a portion where the fluid pipe 20 is not disposed, and the thickness is the height of the fluid pipe 20. It is set to be almost the same as (diameter). The intermediate layer member 30 is formed of a heat insulating material, and for example, a foamed resin such as polyurethane foam, polypropylene foam, polystyrene foam, or the like can be used.

  As shown in FIGS. 1 and 2, the covering member 40 is stacked on the fluid pipe 20 and the intermediate layer member 30. The covering member 40 is formed in a plate shape from a material having higher thermal conductivity than the base member 10, for example, a metal material such as aluminum. Since the back surface of the covering member 40 is in contact with the fluid pipe 20, the heat of the snow-melting fluid flowing through the fluid pipe 20 flows through the peripheral wall of the fluid pipe 20 and the covering member 40. It is quickly transmitted to the surface side, and the snow on the covering member 40 is quickly melted.

  The support member 50 is a member that integrates the fluid pipe 20 and the intermediate layer member 30 between the base member 10 and the covering member 40. As shown in FIG. 2, the support member 50 of the present embodiment includes an end wall member 51 and a flange connecting member 52. The end wall member 51 is made of a channel member made of metal such as aluminum having a substantially U-shaped cross section, and two flange portions 51a and 51a are laminated on the lower surface of the base member 10 and the upper surface of the covering member 40, respectively. A connecting portion 51 b that connects the portions 51 a and 51 a is disposed so as to cover the peripheral surfaces of the base member 10, the intermediate layer member 30, and the covering member 40. The flange connecting member 52 is composed of a rivet or the like, passes through the base member 10, the intermediate layer member 30, and the covering member 40 in the stacking direction, and includes two flange portions 51a of the end wall member 51 disposed as described above. 51a are connected. Thereby, the base member 10, the intermediate | middle layer member 30, and the coating | coated member 40 are integrated with the fluid piping 20 hold | maintained among them.

  By being integrated by the support member 50, the adhesion between the members can be improved and the thermal conductivity from the fluid pipe 20 to the covering member 40 can be ensured well, but the support member 50 has the base member 10 and the covering member 40. Therefore, when the covering member 40 is distorted due to the weight of snow or the influence of heat, for example, near the center of the snow melting panel 1 or the like, the covering member 40 and the fluid piping 20 are disposed. May be separated, and adhesion may be impaired. Therefore, a connecting member 60 such as a rivet that penetrates the base member 10 to the covering member 40 in the stacking direction and connects the base member 10, the intermediate layer member 30, and the covering member 40 is provided at a position adjacent to the fluid pipe 20. Is preferable (see FIGS. 2 and 3). Since the parts adjacent to the fluid pipe 20 are connected by the connecting member 60, even if the covering member 40 is deformed, the adhesion between the fluid pipe 20 and the covering member 40 is not impaired, and good thermal conductivity is achieved. It can be secured. As a position adjacent to the fluid pipe 20 where the connection member 60 is provided, for example, as shown in FIG. 3, the connection member 60 can be provided at an intermediate position between the two adjacent linear portions 23 and 23. However, the closer to the fluid pipe 20, the higher the integrity of the fluid pipe 20 when the covering member 40 is deformed. Therefore, the connecting member 60 is preferably provided as close to the fluid pipe 20 as possible.

  The snow melting panel 1 of the present embodiment is used by being laid on a site such as a front door of a house or a storefront, for example. A snow melting fluid such as hot water having a predetermined temperature flows into the fluid pipe 20 from the inlet 21. The snow melting fluid flows along the piping path of the fluid piping 20 and flows out from the outlet 22. The snow-melting fluid that has flowed out flows directly into a circulation pipe (not shown), where it is reheated as necessary, and is supplied again into the fluid pipe 20 at an appropriate timing.

  In the snow melting panel 1 of the present embodiment, the fluid piping 20 is disposed on the base member 10 having a high heat insulating property having the hollow portion 13, and the periphery thereof is surrounded by the intermediate layer member 30 made of a heat insulating material. The covering member 40 is stacked on the base member 10 and the base member 10 to the covering member 40 are integrated in the stacking direction by the support member 50 and the connecting member 60. Therefore, the heat insulation function of the base member 10 can efficiently transfer the heat to the surface side of the covering member 40 while suppressing a decrease in the temperature of the snow melting fluid flowing through the fluid piping 20, and a high snow melting effect is expected. it can.
