Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat source which is most suitable for laying in various premises such as roads (crosswalks), parking lots, promenades, park squares, factory premises, etc. in cold regions, for example, areas with a lot of snowfall. The present invention relates to a pavement device for a cold region provided with a device.

[0002]

2. Description of the Related Art Conventionally, in regions where the amount of snowfall is large, ice melting snow facilities are provided on roads and the like. When installing this melting ice and snow equipment, excavate the entire area where the equipment is laid in a plane, spread the gravel, tamping and leveling it, and then place the hot water pipes and heating wires for melting ice and snow on the gravel. A heating element such as the above is placed, and asphalt pavement is performed thereon, or bricks, tiles, slabs, etc. are laid one by one to perform paving.

[0003]

However, in the above prior art, the laying work of bricks and tiles requires skill,
There is a problem that the construction period is long and the construction cost is high. On the roads where buried objects, water and sewer pipes, gas pipes, etc. are buried underground, it is often necessary to repair and replace these buried objects, so that they can be rebuilt and restored again. Because of the large number, it is not possible to lay snow melting equipment.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to minimize the work on a construction site, shorten the construction period, and reduce the construction cost.
Moreover, it is an object of the present invention to provide a pavement device for a cold region in which ice melting snow equipment can be laid above an underground buried object.

[0005]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, the feature of the present invention lies in that it comprises a frame, a laying material laid on the frame, and a heat generating device buried on the lower surface side of the laying material. According to the present invention, pavement equipment is manufactured in a factory or the like to have an appropriate size and work on the construction site as much as possible, prepared in advance without being affected by the weather, It is transported and lined up on the ground using a hoist such as a crane truck or a truck with a lift.

In addition, when repairing, inspecting and replacing underground buried objects and various pipes after completion of pavement, the paving equipment is lifted up and temporarily removed, and after completion of the required construction, the paving equipment is restored to its original state. By laying at a position, it can be easily and efficiently restored in a short time. Further, when the present invention is used for a sidewalk in a cold region, since the heating device is provided on the lower surface side of the laying material, the snow accumulated on the laying material can be melted, and the sidewalk can be easily walked. . When used as a floor material in a building hall or the like, floor heating can be performed.

It is composed of The heating device includes a hot water pipe 5 and the like that pass through the heat insulating material 3 and penetrate both ends in the longitudinal direction of the frame 2. The configuration of the level adjustment device A will be described later.

As shown in FIGS. 2 and 3, the frame 2 has a rectangular shape with a suitable size, for example, a width of about 1 m and a length of about 2 m, and a reinforcing rib 6 at the center in the longitudinal direction. A plurality of insertion holes 7 for the hot water pipes 5 are provided in the longitudinal side walls 2A, 2A and the rib 6, respectively, so as to penetrate therethrough.
A plurality of drain holes 8 are provided in each of the width direction side walls 2B, 2B (or the bottom plate 2C).

The hot water pipe 5 is inserted and fixed in the insertion hole 7, and the pipe 5 also plays a role of reinforcing the frame 2.
Note that a heating element such as a heating wire can be inserted into the insertion hole 7 instead of the hot water pipe 5, and the heating element insertion hole can be separately provided. The hot water pipe 5 is provided as close as possible to the lower surface of a pavement finishing material (laying material) such as the tile 4 so that heat from the pipe 5 can be easily transmitted to the tile 4.

FIG. 4 shows an example of the laying state of the paving equipment 1, and the paving equipment 1 is laid in two rows on a sidewalk 11 provided next to the road 9 and via a curb 10. Of these two rows of paving equipment 1, one row is directly laid on the ground with gravel 12 or the like laid down and solidified, while the other row is buried adjacent to the building 13 such as ductile cast iron or It is laid on a common groove frame 14 made of a steel plate (sometimes made of concrete), and serves as a lid for an upper opening 14A of the common groove frame 14.

Various pipes 16 such as water and sewer pipes and gas pipes are provided in the common groove frame 14. In the above embodiment, the width of the sidewalk 11, that is, the curb 10
By setting the distance from the building 13 to about 2 m, the pavement equipment 1 can be vertically arranged in two rows using a lifting machine such as a crane truck or a truck with a lift. Then, the level of each pavement device 1 is determined by the level adjustment device A, and a step between adjacent pavement devices 1 is eliminated.

Although not shown, both ends of each hot water pipe 5 of the paving equipment 1 are connected in a watertight manner automatically or manually by placing the paving equipment 1 adjacently at the time of laying. Conversely, at the time of removal, a pipe joint that can be separated automatically or manually is provided. Therefore,
When inspecting, repairing, replacing, etc. the various pipes 16 in the common groove frame 14 as well as the hot water pipes 5 and their pipe joints, the pavement equipment 1 is lifted and temporarily removed, and after completion of the repair work, etc. The pavement device 1 may be returned to its original position and laid, and work can be performed easily and efficiently in a short time, and the cost of incidental works such as repairs can be greatly reduced.
