Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is applicable to facilities or structures that have flat locations in cold regions, such as roads, bridges, airport runways, grounds, parking lots, and even buildings. This invention relates to a planar block used on roofs, etc., to prevent or melt ice or snow on the surface.

(Prior art and its problems) In order to prevent and melt ice and snow on flat facilities or structures such as roads in cold regions, there are methods to install sprinklers and sprinkle water on the road surface. , a method of spraying calcium chloride, or a method of constructing hot spring piping under the road surface in hot spring areas to utilize hot spring heat.

However, installing sprinklers is costly, and the nozzles are easily clogged with dirt and debris, which increases the water pressure and causes water to spout from unclogged nozzles, causing a nuisance to pedestrians. be. In addition, spraying calcium chloride is a complicated process, tends to cause the death of surrounding plants, and requires a large amount of money.Furthermore, although hot spring piping can solve the above-mentioned problems to some extent, it cannot be used outside of hot spring areas. There are circumstances that make it impossible.

Therefore, the present inventor developed a snow and ice melting piping device as shown in Japanese Patent Application No. 166504/1982. This involves arranging a large number of pipes through which a heat medium flows in parallel at predetermined locations, arranging an artificial header and an outlet header in a direction perpendicular to the pipes, and connecting one end of the pipes to the other. The pipe is connected to an inlet header and the other end is connected to an outlet header, and the inlet header is connected to a heat medium supply source to circulate the heat medium through the pipe to heat a predetermined location. be.

However, when installing the above-mentioned snow melting/water melting piping device on a road, for example, many pipes are arranged in parallel under the road surface, one end of which is connected to the artificial header, and the other end is installed in parallel. After connecting the road to the exit header, it is necessary to pour concrete or asphalt to form the road surface and pave it. therefore,
All work is done on-site, requiring a lot of time and labor, and requires traffic to be stopped for long periods of time, making construction difficult on roads with heavy traffic. In addition, if the pipes that circulate the heat medium are not installed at a certain depth relative to the road surface, even if the road surface is heated by the heat medium, it will not be possible to heat the road surface uniformly. Burying the pipe in the ground is very complicated work, and even if a part of the pipe becomes damaged or has a pinhole, it is difficult to find the part, and furthermore, when repairing, it is necessary to clean the road surface each time. There is a problem in that repair work requires a lot of effort and money, such as digging and resurfacing.

(Object of the Invention) This invention has been made by focusing on the above-mentioned circumstances, and its purpose is to spread the heat medium over a wide area by laying blocks at the site and connecting the heat medium flow passages in the blocks. To provide a planar block that can form a distribution route, is easy to construct, and can reduce costs.

(Means and effects for solving the problem) This invention has the following features:
A block body whose surface is formed into a rectangular shape made of a pressure-resistant material has heating medium flow passages arranged in parallel on the surface thereof, and a plurality of block bodies are laid and communicated with each other. By circulating a heat medium through the block, the surface of the block body can be heated.
