DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road surface heating panel used when a heating tube is buried in a road surface to prevent snow and freezing on the road surface, and a pipe to which a heating tube is attached using the road surface heating panel. Road construction method.

[0002]

2. Description of the Related Art Conventionally, a heating pipe is buried below a road surface such as a road, a parking lot, an entrance passage, etc., and a heated heat medium such as hot water flows through the heating pipe to release the heat medium. There is known a method of heating a road surface with heat to prevent snow, freezing, and the like on the road surface. For example, as described in Japanese Patent Publication No. 53-4740, a wire mesh is laid on a road surface, a heating tube is fixed on the wire mesh with a fixture such as a wire, and piping is performed. Asphalt is placed on the heating tube. There is known a method of paving with mortar or the like.

[0003]

However, in the above-mentioned method, the operation of fixing the heating tube using the fixing tool is difficult because the operation is performed in the middle posture, and the workability is poor and the operation time is long. Also, a large number of workers were required. In addition, since the conditions at the piping site are all different, it is necessary to appropriately adapt the pattern of the piping according to the construction site. Therefore, a skilled worker is required for the piping work.

Further, since a heating pipe is directly provided on a roadbed, heat of a heat medium such as hot water flowing through the heating pipe escapes to the ground. Therefore, there is a problem that heat more than necessary is required, and thermal efficiency is poor. Therefore, an object of the present invention is to provide a road surface heating panel with good workability and high thermal efficiency that can be piped by a piping method that does not require a skilled person, and a pipeline construction method using the road surface heating panel.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and a road surface heating panel is a road surface heating panel comprising a heat insulating plate and a heating tube holding block. Holes are provided in the upper surface of the passage for mounting the heating tube, and the heating tube holding block is higher than the depth of the hole, the lower portion has a shape that can be inserted into the hole of the heat insulating plate, and the heating tube is fitted on the upper portion. It is provided with a matching groove.

[0006] In addition, in the method of constructing a pipe, a heat insulating plate of the road surface heating panel is laid, and a heating pipe holding block is inserted into a hole provided in a passage for mounting a heating pipe through which the heating pipe passes. A heating pipe is fitted into a groove provided in the upper part of the block, piping is performed, and pavement material is provided from above. As the heat insulating plate used for the road surface heating panel of the present invention, any plate may be used as long as it has good heat insulating properties, but a synthetic resin foam such as a polyethylene resin foam, a polystyrene resin foam, and a polyurethane resin foam. Is preferred. As the heating tube, a synthetic resin tube which is easy to construct is preferable, and specifically, a nylon resin, a cross-linked polyethylene resin, a polybutene resin, and a cross-linked polyethylene resin are reinforced with a metal such as aluminum within the thickness. A metal-reinforced composite pipe is used as appropriate.

In the present invention, the shape of the hole provided in the heat insulating plate and the shape of the lower portion of the heating tube holding block may be arbitrary. For example, the section may be arbitrarily set in a place where the heating tube holding block is used only in a state where the heating tube holding block is oriented in one direction. When changing the direction in various directions, the shape may be circular. Further, this hole may be a hole that penetrates below the heat insulating plate, or may be a halfway hole.

In the present invention, the heat insulating plates may be used independently one by one. However, it is usually preferable to lay a plurality of the heat insulating plates and attach a heating tube thereon to easily heat a wide area. . At this time, it is preferable to connect a heating tube attached to a plurality of heat insulating plates to a heating tube attached to an adjacent heat insulating plate or to bridge a heating tube. As described above, in order to connect or bridge the heating tube to the heating tube of the adjacent heat insulating plate, it is necessary to make the entrance and exit of the heating tube attachment passage almost at the same position.
Further, the heat insulating plate may have an appropriate shape, but may be formed in a rectangular shape so as to be easily laid.

[0009] Various structures are possible to lay out and arrange a large number of heat insulating plates and mount a heating tube thereon. The best structure among them is as follows. The heating pipe mounting passage of the heat insulating plate passes from one side to the opposite side, a straight part that enters from one side, turns at this side, and the heating pipe that goes and returns. By combining various types of heat insulating plates with the tip portion connecting the two, various heat insulating plates can be laid and arranged, and a wide area can be heated simply by attaching a heating tube to the heat insulating plates.

As the pavement material used in the pipeline construction method of the present invention, all conventionally used pavement materials can be used.
For example, it may be asphalt, concrete or mortar. Also, it may be gravel such as ballas, crushed stone, or a mixture of cement and gravel.

[0011]

On the upper surface of the road surface heating panel according to the present invention, there is provided a heat insulating plate provided with holes at locations where heating pipes are to be mounted, and a heat holding block whose lower portion is formed into the hole. A passage for the heating tube can be provided in the hole of the plate. Moreover, since a groove for fitting the heat insulating tube is provided at the upper portion of the heating tube holding block, the heating tube can be easily fitted by fitting the heating tube into this groove. When the heating tube is mounted on the heat insulating plate in this way, since the heat insulating plate is provided below, it is difficult for the heat of the heating tube to escape downward, and therefore, heat loss is small.

In order to attach various shapes of heating tubes to the heat insulating plate, holes are provided at various locations in the heating tube mounting passages corresponding to the various shapes of heating tubes. If the heating tube holding block is inserted only into the hole where the heating tube is to be actually passed, the number of heating tube holding blocks will decrease, and at the same time, since the heating tube holding block is not attached to an extra place, it will be a hindrance when attaching the heating tube. do not become.
