Description

[Detailed description of the invention] [Field of industrial application] The present invention is a floor that is equipped with a heating function at the bottom of the floor of a building, and also has a function of controlling pests, mainly termites. It concerns heating structures.

[Conventional technology]

Conventional floor heating systems include electric heating and hot water circulation methods, but in the hot water circulation method, pipes such as steel pipes and vinyl pipes are laid under the floorboards, and hot water at 60 to 80 degrees Celsius is flowed through these pipes. It is designed to circulate.

Conventionally, the spaces between the pipes through which hot water circulates, that is, around the pipes, are filled with mortar, concrete, etc. Styrofoam and other insulation materials are also used for filling. .

[The problem that the idea attempts to solve]

In the hot water circulation system, where the spaces around the pipes are filled with mortar or concrete, these materials have relatively good thermal conductivity, so heat easily escapes to the underfloor, which is not at all efficient. Moreover, it has the disadvantage of poor heat retention and is easily cooled, and furthermore, this mortar, concrete, etc. are also soaked by termites, so there is a problem in terms of termite prevention.

On the other hand, pipes filled with Styrofoam or other insulation materials in the void surrounding the pipes have an insulating effect and do not cool easily and have good thermal efficiency, but they are highly susceptible to termites and can cause damage to buildings. Therefore, it is judged to be inappropriate for a floor heating structure that will be used for a long period of time.

This invention was developed with the aim of obtaining floor heating that does not have the above-mentioned problems.It has good thermal efficiency, does not cool easily, is effective in controlling termites, and has a short construction period and low equipment and fuel costs. The aim is to provide a floor heating structure that is

[Means to solve the problem]

While we were considering various filling materials to fill the voids around the pipes of underfloor heating, we discovered that sand, which can be heated relatively easily, is difficult to cool down after experiencing the heat of sand on a sandy beach in midsummer. They realized that termite prevention could also be achieved by mixing powdered insecticides into the product, and completed the present invention.

In other words, the present invention is based on a floor heating system in which pipes for circulating hot water are laid under the floorboards, and the spaces around the pipes are filled with a mixture of dry sand and termite powder. The gist is the characteristic underfloor heating structure.

The present invention will be explained in detail with reference to the drawings.

FIG. 1 is a partial vertical sectional view of a floor having the structure of the present invention.

FIG. 2 is a plan view with the floorboard removed from FIG. 1.

As shown in these figures, in the present invention, a pipe 2 is laid out under a floorboard 1, and the space around the pipe 2 is filled with a mixture of sand 3 and termite powder 4. That is what it is.

In the drawing, a floor stand 5 is supported by pillars 6, a support plate 7 is stretched over the floor stand 5, and a floor plate 1 is provided on top of the support plate 7 via a tarp wood 8.

Further, as shown in FIG. 1, preferable results can be obtained by layering glass wool 9 as a heat insulating material under the sand 3 and termite control agent powder 4 in the present invention. That is, the sand 3 and termite control agent powder 4 may be filled onto the glass wool 9 through the felt 10, and the sand 3, termite control agent powder 4, glass wool 9, etc. are held by the receiving plate 7. -ing

Only the upper surface of the pipe 2 is in contact with the floorboard 1, and most of the outer circumference of the pipe 2 is buried in sand 3 and termite control agent powder 4.

As the pipe 2 in the present invention, for example, a polyvinyl chloride pipe or a copper pipe with a diameter of 10 to 15 mm can be suitably used. It's the temperature.

Various water heaters can be used to supply water to this pipe 2, such as a heater with an oil water heater, a heater with a gas water heater, and other general hot water boilers, and if necessary, a dedicated remote control can be attached. be.

The greatest feature of this invention is that the gap between the pipes 2 is filled with a mixture of sand 3 and termite control powder 4. River sand, beach sand, etc. can be used as the sand 3, and the particle size is finer. Sand 3 is preferable because it provides a high packing density, but sand 3 having an average particle size of about 0.5 to 3 mm can be used, and sand 3 having an average particle size of about 1 mm is particularly desirable.

In addition, it is preferable that this sand 3 does not contain moisture, and it is necessary that the sand 3 is dry, although not completely dry, and must be dried to the extent that it does not introduce moisture to the floor or its surroundings before use. That's what I do.

The termite control agent powder 4 in the present invention may be a general commercially available product, such as a powder sold under the trade name "Secoa Killer" by Toyo Satsushi Co., Ltd., which can be suitably used.

The ratio of this termite control agent powder 4 to sand 3 should be about 3 to 15 kg per sand 31000, and it may be increased or decreased as appropriate depending on the humidity condition of the construction site. It is also possible to use 20 kg or more of the repellent powder 4 per 1000 parts of the sand.

[Effect]

The present invention has the above-mentioned configuration, and since the filling material filling the gaps between the pipes 2 is mainly sand 3, the heating efficiency is high, and although it is heated relatively quickly, it is difficult to cool down, and the heat retention effect is better than that of the conventional one. This makes it superior to mortar and concrete.

In addition, since the termite control agent powder 4 is mixed with the sand 3, it can control not only termites but also centipedes and other pests, and has an extremely excellent effect of protecting the entire floor and even the building from termite damage. It demonstrates this.

In addition, the termite control effect is at least 8 to 10
It can last for years, and if the floorboards 1 are turned over every 10 years and termite control powder 4 is additionally sprayed, termite control can be achieved semi-permanently.

Furthermore, if glass wool 9 is layered under the sand 3 etc. through felt 10, heat will not escape and the thermal effect can be greatly improved, and moreover, this will become a cushion material and prevent floor rattles. .

When constructing the structure of the present invention, various commercially available hot water boilers can be used, and the space around the pipe 2 is simply filled with a mixture of sand 3 and termite control agent powder 4, making the construction easy and short. Since the filling material is mainly sand 3, which is inexpensive, it is very cost-effective, and the fuel cost is also low because it has good thermal efficiency.

〔Example〕

The floor structure of a room with an area of 13.2 m ² (8 tatami mats) is a 12 mm thick control panel placed on a floor stand 5 made of a large wooden board as a receiving plate 7, and 14 tall wood 8 placed on top of it.
Glass wool 9 as a heat insulating material was laminated to a thickness of 10 cm on the upper surface of the receiving plate 7 between the barrel trees 8 at equal intervals.

A total of 17 kg of felt 10 was spread on top of the glass wool 9, and then 120 m of polyvinyl chloride pipe 2 with a diameter of 13 mm was spread over the entire surface evenly.

Next, a mixture of 3,600 g of sand made by drying river sand with an average particle size of about 1 mm and 45 kg of termite control agent powder was filled into the gap between the pipes 2.

As the termite control agent powder 4, Secor Killer (trademark) manufactured by Toyo Satsushi Co., Ltd. was used.
The pipe 2 is supported by using a barrel tree 8, and its height is made to be the same as the upper end of the barrel tree 8 where only the top surface of the pipe 2 is exposed.

A decorative floor with a thickness of 12 mm was then laid as floorboard 1.

In this floor heating structure, an oil heater (Noritz floor temperature boiler) was used to circulate hot water of about 70 to 75 degrees Celsius through pipe 2 at a rate of about 4 per minute.

This hot water supply was started at 9 a.m. with a floor temperature of 4℃ and room temperature (height
1m) Started at 6°C, the bed temperature was 9°C and the room temperature was 8°C at 11:00, the bed temperature was 14°C and the room temperature was 12°C at 1:00 pm, and these temperatures were maintained until 7:00 pm.

At 7pm, I turned off the boiler to stop the circulation of hot water, but even at 9pm, both the floor temperature and the room temperature remained at 12°C, and despite the outside temperature being as low as 5°C, the heat retention was quite good. At 11 p.m., the floor temperature and room temperature were both 10 degrees Celsius, and it wasn't until 11 p.m. that they both fell below 10 degrees Celsius.

The amount of kerosene required during the 10-hour operation from 9:00 to 19:00 was approximately 4.

In addition, the time and effort required to construct the floor heating structure is as follows:
The work was completed in a short period of two days with two workers.
