Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating structure for burying a pipe in a floor to supply hot water to heat a floor and a room, and to a method of constructing the same.

[0002]

2. Description of the Related Art Conventionally, indoor heating devices include petroleum and oil.
Gas and electric stoves, fan heaters, etc. are used, but these methods not only increase the utility cost, but also cause the heat to be concentrated on the upper part of the room, so the whole room is poorly kept warm and there is no effect of head and foot heat .

[0003] Above all, oil stoves and fan heaters generate a large amount of moisture during combustion. For example, 1 liter of kerosene generates 1.13 liters of water (steam) equal to or greater than the amount of oil. Moisture generated by this combustion is a factor for shortening the life of RC condominiums and wooden houses.

[0004] A large amount of water vapor generated by combustion is RC
It adheres to the surface of the structure, penetrates into the skeleton, acts on the aggregate sea salt, and promotes the corrosion of the reinforcing steel, causing fatal cracks in the skeleton in an early age. On the other hand, when wooden is wet, it is rotted and attacked by termites, shortening its life. Thus, various bad phenomena due to combustion also impair health, and the damage is enormous and a social problem.

Therefore, floor heating has been developed for the purpose of burying pipes in the floor to supply hot water to heat the floor and the room. For example, in Japanese Patent Publication No. 58-52129, styrene foam is laid on concrete on a suitable foundation, a wire mesh is interposed in the mortar, and a hot water pipe is arbitrarily formed in the mortar. A floor heating method is disclosed for a building in which a joint of a breathable elastic member is provided between a floor, a base and a sill.

[0006]

However, in the invention described in Japanese Patent Publication No. 58-52129, a hot water pipe is buried in a mortar, a wire mesh is laid on the mortar, and the mortar is filled on the upper surface. Therefore, it is necessary to apply the mortar twice, and the mortar becomes thick and the rise time of heating becomes long.

Further, when the hot water pipe is simply buried in the mortar, the hot water pipe may be displaced when the hot water pipe is laid and filled with the mortar, so that attention is required for the construction and it takes time and effort. Furthermore, in order to prevent the hot water pipe from shifting, it is necessary to wait until the mortar in which the hot water pipe is buried to a certain degree before applying the mortar twice, so that the application time becomes long.

Therefore, the present invention relates to a floor heating structure,
It is an object of the present invention to make it possible to easily perform a hot water pipe without shifting a hot water pipe during mortar filling, and to shorten a rising time of heating.

[0009]

The floor heating structure according to the present invention comprises:
A heat insulating material, a wire mesh, a hot water pipe fixed to the wire mesh, and a mortar are sequentially laid on a concrete foundation. In a state where the hot water pipe is fixed to the wire mesh laid on the heat insulating material in this manner, heat is uniformly transmitted from the hot water pipe to the wire mesh. In addition, the wire mesh protects the hot water pipe against a disaster such as twisting, displacement, or earthquake of the house, so that cracks and cracks in the hot water pipe are prevented. In addition, since the hot water pipe is fixed to the wire mesh, the hot water pipe does not shift when filling the mortar, and the construction can be performed easily and in a short time. Therefore, the mortar can be filled only once, and the mortar thickness can be made thinner than before, and the heating start-up time can be further reduced.

Furthermore, it is desirable to provide a heat insulating material on the side surface of the concrete foundation. Conventionally, insulation was provided only on the concrete foundation.However, by providing insulation on the side of the concrete foundation and covering the periphery of the concrete foundation, the heat inside the room can conduct heat on the side of the concrete foundation. Thus, escape to the outside can be prevented and the temperature inside the room can be kept constant. In addition, since the heat on the indoor side does not escape to the outside, it is possible to further reduce the rise time of heating.

The mortar has a thickness of 50 to 70 m.
m, more preferably 50 to 60 mm. Since the hot water pipe is fixed to the wire mesh and the mortar can be filled at one time, the place where the mortar was previously filled up to about 100 mm on the hot water pipe can be reduced in thickness to 50 to 70 mm. Become like By reducing the thickness of the mortar in this manner, the surface temperature of the hot water pipe, which had conventionally been required to be 60 to 65 ° C., can be set to 45 to 50 ° C., and a sufficiently low room temperature can be secured.

If the thickness of the mortar is less than 50 mm, the strength of the mortar is insufficient, so that cracks and cracks may easily occur. On the other hand, when the mortar thickness is larger than 100 mm, it becomes necessary to increase the surface temperature of the hot water pipe as described above. In consideration of the strength of the mortar and the surface temperature of the hot water pipe, the mortar thickness is more preferably set to 50 to 60 mm.

In the floor heating method of the present invention, a heat insulating material is laid on concrete having a suitable foundation, a wire mesh is laid on the heat insulating material, and a hot water pipe is laid on the wire mesh and fixed to the wire mesh. The mortar is filled from above.

As described above, by laying a wire net on the heat insulating material, fixing the hot water pipe on the wire net and then filling the mortar, the hot water pipe is not displaced at the time of filling the mortar, and the construction is easy and short. It is possible to do with. Therefore,
The mortar can be filled only once, and the mortar thickness can be made thinner than before, and the heating start-up time can be further reduced.

FIG. 1 is a partially cutaway perspective view showing a floor heating structure according to an embodiment of the present invention, FIG. 2 is a longitudinal sectional view showing details of the floor heating structure of FIG. 1, and FIG. It is a perspective view which shows the fixed state of the hot water pipe in detail of the A section of FIG.

As shown in FIGS. 1 and 2, the floor heating structure in the present embodiment mainly includes a masa earth 1 and a crusher orchid 2 (stone is crushed to an appropriate size) in a space surrounded by a cloth foundation 9. ) And a vinyl sheet 3 are laid in this order, and concrete is filled so as to be flush with the upper end surface of the cloth foundation 9, and the concrete foundation 4 is applied. The mortar 11 and the felt 12 are placed on the upper end surface of the cloth foundation 9. The base 13 is fixed through the slab, and a styrofoam 5, a wire mesh 6, a hot water pipe 7, and a mortar 8 as a heat insulating material are laid in order on a concrete foundation 4.

Here, the styrofoam 5 is the same polystyrene foam as styrofoam which is also used as a heat insulating material. The styrofoam 5 is different in production method from styrofoam. Styrofoam is called a beaded polystyrene foam, while styrofoam is called an extruded polystyrene foam. Since the styrofoam 5 has a lower thermal conductivity than styrofoam and a higher heat insulating property, when used as a heat insulating material, an excellent heat insulating effect can be obtained.

The wire net 6 is formed by reinforcing steel bars having a diameter of 3 mm in a grid pattern at intervals of 100 mm. The hot water pipe 7 is a pipe made of a polymer resin plastic and having a diameter of about 16 mmφ. The high-temperature plastic pipe 7 made of a polymer resin plastic is flexible and has high resistance to acid and alkali, so there is no fear of corrosion, and since it is protected by the mortar 8, there is no fear of water leakage. In addition, it is sanitary because there is no water pollution due to generation of red rust and blue rust and elution of harmful substances as in metal tubes. In addition, since the frictional resistance is small and the scale and the like are not easily attached, the flow rate does not decrease due to aging as compared with the metal pipe. Therefore, such a floor heating structure in which the hot water pipe 7 made of polymer resin plastic is solidified by the mortar 8 is as follows.
It can withstand many years of use and requires no maintenance.

Such a hot water pipe 7 is spirally arranged on the wire mesh 6, and is fixed to the wire mesh 6 using a binding wire (wire) 14 as shown in FIG. At this time, if the hot water pipe 7 is fixed to the overlapping portion (overlapping portion) 6a of the reinforcing bar of the wire mesh 6 by cross-linking, the movement of the hot water pipe 7 is restricted by the overlapping portion 6a, and the mortar 8 is filled. At times, the hot water pipe 7 is harder to shift.

The mortar 8 is filled at a stretch from the state where the hot water pipe 7 is fixed to the wire mesh 6 in this way. Here, since the mortar 8 is filled at a stretch, the mortar thickness is 50 to 70 mm, more preferably 50 to 70 mm, which is thinner than the conventional structure.
It is possible to construct so as to be 60 mm, and in the present embodiment, it is constructed so as to be 50 mm.
Flooring, tatami and carpet 1 on this mortar 8
Lay 5 and finish.

As described above, since the mortar 8 is filled after the hot water pipe 7 is fixed on the wire mesh 6, the hot water pipe 7 does not shift when the mortar 8 is filled, so that the construction can be performed easily and in a short time. . In addition, since the mortar thickness is reduced by completing the mortar filling only once, the distance for transmitting heat to the room via the mortar 8 is shortened, and the rising time of heating can be further reduced.

In such a floor heating structure, the hot water pipe 7
Is heated by circulating hot water of about 50 to 55 ° C. heated by a boiler (not shown) provided outside the house to maintain the surface temperature of the hot water pipe 7 at 45 to 50 ° C.
Since the styroform 5 is in contact with the wire mesh 6 below the wire mesh 6 to which the hot water pipe 7 is fixed, the heat of the hot water pipe 7 is blocked by the styroform 5 and is efficiently transmitted to the wire mesh 6 uniformly. Then, the heat transmitted over the entire wire mesh 6 is transmitted to the room through the mortar 8.

As described above, the styrofoam (insulation material) 5 is laid on the concrete foundation 4, the wire mesh 6 is laid on the styroform 5, the hot water pipe 7 is laid on the wire mesh 6 and fixed to the wire mesh 6. Apply mortar 8 thinly from above to 50-7
If the floor heating structure is filled with 0 mm, the hot water pipe 7 to be heated
Even if the surface temperature of the conventional device is required to be 60 to 65 ° C., but is set to a lower temperature of 45 to 50 ° C., a room temperature similar to the conventional one can be sufficiently secured.

Further, by making the mortar 8 filled on the hot water pipe 7 thinner, the rise time of the bed temperature can be further shortened. Conversely, when the temperature of the floor rises due to solar radiation or the like, the temperature can be lowered faster than before by stopping the heating of the hot water pipe 7. That is, the time required for raising and lowering the temperature of the floor is shortened, and the temperature can be adjusted more smoothly than before.

Therefore, the energy (fuel cost) of the boiler required to heat the hot water circulating in the hot water pipe 7
And running costs can be reduced. In addition, since the temperature of the hot water circulating in the hot water pipe 7 is lower than before, the influence of the flooring and tatami laid on the mortar 8 or the expansion and contraction of the base portion due to heat is reduced, and the service life of these is reduced. And the durability of the whole building such as a house is improved.

Further, in the present embodiment, by fixing the hot water pipe 7 on the wire mesh 6, the twist of the house,
Wire mesh 6 is connected to hot water pipe 7 for disasters such as slippage or earthquake.
Therefore, cracks and cracks in the hot water pipe 7 can be prevented. Therefore, it is possible to prevent water leaks due to cracks or cracks in the hot water pipes 7 and deterioration of houses, especially wooden buildings, etc. due to the water leaks.

In this embodiment, a styrofoam 10 as a heat insulating material is further provided on the side surface of the foundation. The side surface portion of the foundation referred to here is the inner side surface portion of the cloth foundation 9 and is the space between the masa soil 1, the crusher orchid 2, the vinyl sheet 3, and the concrete foundation 4 and the cloth foundation 9. In this space, a styroform 10 is provided so as to be in contact with the styroform 5 laid on the concrete foundation 4, thereby preventing the indoor heat including the geothermal heat from escaping to the outside via the cloth foundation 9.

As described above, by providing the styrofoam (insulation material) 5 also on the side surface of the rising portion of the foundation, it is possible to prevent the heat of the indoor side including the geothermal heat from being conducted through the foundation and escaping to the outside. Can be kept constant. In addition, since the heat on the indoor side does not escape to the outside, it is possible to further reduce the rise time of heating.

Reference numeral 3 denotes a pair glass (double glass) for enhancing the heat insulating effect, and the roof 24 is also covered with a heat insulating material having a thickness of 80 mm similarly to the wall 22. As described above, by making the entire house 20 have a high heat insulation and high airtight structure, the floor heating structure in the embodiment of the present invention works more effectively.

As shown in FIG. 4A, in winter (when the outside air temperature is 0)
In the case of (° C.), the styrofoam (insulation material) 10 is provided on the side surface of the concrete foundation 4 of the foundation portion 21, so that in addition to the heating effect by the floor heating, the heating effect by the geothermal heated by sunlight can be obtained. Become. Therefore, when warm water of about 50 to 55 ° C. is circulated so that the surface temperature of the hot water pipe 7 becomes 45 to 50 ° C., the room temperature becomes 20 to 50 ° C.
It is maintained at a comfortable temperature of 23 ° C., and the energy required for the boiler for heating the water can be saved by lowering the temperature of the hot water than before.

On the other hand, as shown in FIG. 4B, in the summer season (outside temperature 36 ° C.), in addition to the cooling effect by the cooler 25 provided inside the house 20, the geothermal ( The heat inside the room is taken away by the cold heat, and the room is cooled. Therefore, the room is kept at 25 ° C. in all rooms from the first floor to the third floor, and the energy required for the cooler 25 can be saved.
