Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention provides a house with high heat insulation and high airtightness, effectively utilizing natural heat and exhaust heat from the house to save energy, high sound insulation and high durability. Regarding the construction method of building the house.

[0002]

2. Description of the Related Art Conventionally, there have been proposed various technologies relating to a house which is highly airtight, highly heat insulating, has a ventilation space, can be ventilated, and has improved cooling and heating efficiency.

However, the performance of all conventional houses is not sufficient. That is, even if an air conditioner is installed in each living room, for example, even if the room is warm, the corridor, toilet, dressing room are cold, etc. , The humidity is uneven. Further, in winter, dew condensation occurs on the window glass, a large amount of mold and mites are generated on the walls and ceiling, which may cause asthma and atopic dermatitis, and stain the house. In addition, since ventilation under the floor is not taken into consideration, odors under the floor are generated and damp, which shortens the life of the house. Further, there is a drawback that living odors such as toilet and kitchen odors are not exhausted sufficiently, the concentration of carbon monoxide and carbon dioxide in the room rises, and that outside noise invades and indoor noise is emitted. there were.

[0004]

Therefore, the present invention effectively utilizes natural energy and waste heat to save energy and to prevent dew condensation without causing temperature unevenness.
It is an object of the present invention to provide a house that has high sound insulation and does not diffuse a living odor, and a method for constructing the house.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a concrete foundation part in which a heat insulating material is buried to form an underfloor that is closed to the outside air, and an aluminum-coated heat insulating material which is affixed to the outside of an inner wall material. An outer wall structure that forms an outer wall ventilation layer that communicates from the ground to the roof between the board and the outer wall material,
A roof ventilation layer that communicates with the outer wall ventilation layer is formed between the outer roof material and the aluminum-coated heat insulation board, and a roof structure in which a ridge ventilation section is formed at the top of the roof ventilation layer and circulates in all rooms in the house A high airtight and highly heat insulating house is constructed by an air circulation type air conditioner. Also, a concrete foundation is formed on the whole surface under the floor while burying a heat insulating material, and the concrete foundation is closed to the outside air. Forming the underfloor, affixing an aluminum-coated heat insulation board on the outside of the inner wall material, forming an outer wall ventilation layer that communicates from the ground to the roof part between the heat insulation board and the outer wall material, and aluminize the heat insulation board and the outside By forming a roof ventilation layer that communicates with the outer wall ventilation layer with the roof material, forming a ridge ventilation section at the top of the roof ventilation layer, by providing an air circulation type air conditioner that circulates all the indoor rooms, High airtightness It is obtained by the construction methods of heat a house.

[0006]

Since the present invention is constructed as described above, it receives heat from the underfloor with little temperature change throughout the year, and prevents the indoor heat from being rapidly dissipated to the underfloor. The heat that is about to be transferred from the roof and the outer wall to the indoor side by the ventilation path that goes through the layers to the building ventilation port is dissipated to the outside from the building ventilation port by the ventilation flow, and the heat conduction resistance of the heat insulation board causes the heat of the outer wall Prevents the propagation of radiant heat from the inner surface to the indoor side. The heat in the room is prevented from being dissipated to the outside by the heat insulating board, and a temperature difference with the outer wall side is prevented from being generated to prevent dew condensation. In addition, since the inside of the room is highly airtight with the outside, there is little heat leakage and high sound insulation, and the solar heat from the invasion of solar radiation in winter is not taken into the room and escaped. The difference is reduced, dew condensation is prevented, and the living odor is not diffused to other rooms by finally inhaling the air from the toilet, kitchen, etc. directly into the air conditioner.

[0007]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the entire structure of a house according to the present invention. In constructing this house, foundation work as shown in detail in FIG. 2 is performed. That is, the ground 1 is excavated to a predetermined depth and shape, and the split stone 2 is laid. The excavated ground at that time forms a slope 3 in a portion from the planned outer periphery of the concrete foundation to the underfloor.
A crushed stone 4 is compacted by rolling on the crushed stone 2, and a moisture-proof polyethylene film 5 is attached to the entire surface while taking an appropriate overlap margin and adhering by taping. On the polyethylene film 5, there is a heat insulation made of hard urethane foam with a thickness of about 25 mm whose outer periphery is covered with polyethylene film moisture-proof paper in the range of approximately 1 m extending from the slope 3 and the upper end of the slope 3 to the floor. Board 6
And place it. Reinforcing bars 7 are arranged together with the formation of the formwork, concrete is poured into the formwork, and the upper surface of the underfloor foundation part 8 is properly arranged to cure the concrete. A hard urethane foam insulation board 10 for concrete driving having a thickness of about 30 mm is attached to the outer periphery of the foundation rising portion 9, and lath is applied to the upper surface thereof to hold the mortar 11 with a metal iron. The pressing concrete 12 is arranged on the upper surface of the polyethylene film 5 on the crushed stone 4 which is compacted at the outer periphery of the lower end of the heat insulating board 10, and the soil excavated around the outer circumference of the foundation rising portion 9 is backfilled to complete the foundation formation.

On the upper end surface 13 of the foundation rising portion 9, a base 15 made of wood such as hiba, cypress, chestnut, etc. having high moisture resistance is provided by interposing a base isolation packing 14 which also uses a base isolation washer.
Place the various pillars on it. At that time, the underfloor 14 of the floor 13 on the first floor is airtightly shielded from the outside air,
Internally open. An interior material 16 is attached to the interior side of the pillar 15 assembled on the base, and a rigid urethane foam having a thickness of about 40 mm as the heat insulation board 17 is attached to the outside. As the hard urethane foam, for the outer wall surface and the roof surface, kraft paper coated with vinyl on the outer surface and aluminum foil coated with vinyl on the inner surface are used. At this time, the aluminum foil on the indoor side acts as an airtight layer, and the kraft paper side on the outdoor side acts as a layer for preventing the gas inside the urethane from escaping. Then, a sponge-like double-sided airtight tape is previously attached to the joint portion in order to make the airtight layer on the aluminum foil side of the heat insulating board 17 continuous. Note that, hereinafter, the material will be generically referred to as a heat insulating board having an aluminum foil coated with vinyl.

On a portion of the constructed house facing the outer wall, except for windows and the like, a heat insulating board made of the above vinyl coated aluminum foil is stuck. In addition, at the portion where this heat insulating board comes into contact with various structural members 18 such as hanging members of the vertical furring strip, air is prevented from leaking through the gap between the two members and the airtight layer is formed by following a slight step. A sponge-like double-sided airtight tape is attached to the aluminum foil side of the heat insulating board to enable continuity, and a waterproof tape 20 is attached from the outside to protect the heat insulating board. Furthermore, in order to close the space formed in the upper end portion of the heat insulating board 10 attached to the outer periphery of the rising portion 9 of the foundation in a portion in contact with the structural material 18, and to prevent a gap from occurring due to an earthquake or other behavior, Silicon 21 is continuously filled in this space with a sponge-like double-sided airtight tape and sealing is performed.
Before attaching the heat insulation board, a sponge-like double-sided airtight tape is attached to the joint part in advance to ensure airtightness, and the waterproof tape or silicone may cause voids such as the outer joint part of the heat insulating material. For any part, one of them is appropriately selected and applied to prevent the gas from flowing out inside the heat insulating board and extend the life of the heat insulating board itself.

A space having a thickness of about 30 mm is formed on the outer side of the heat insulating board 17 by a vertical furring strip 22 to fix an outer wall member 23. This void forms an outer wall ventilation layer 24, the lower end of which opens at a portion close to the ground 1, the upper end of which opens in a roof ventilation layer 19 described below, and the roof surface and outer wall are heated by sunlight, Conducting heat to the back surface of the outer wall ventilation layer 24
When the inside air is warmed, the air rises due to the chimney phenomenon due to the pressure difference between the inlet and the outlet, passes through the roof ventilation layer, and the air in the vicinity of the ground is sucked through the opening 25 for continuous ventilation.

Since air conditioned like the room is circulated in the surrounding walls, floor, and ceiling by the airtight construction method, the surface temperature of these is always kept in equilibrium with the room air. As in the conventional construction method, convection occurs because heat is applied only to a part of the indoor air, and heat is transferred toward the external openings on the relatively low temperature side, the surrounding walls and ceiling, and the floor. There is no phenomenon that heat from reverse radiation is taken away. Further, the heat conduction to the outdoor side is prevented by the heat insulating board 17 having high airtightness and very low heat conductivity. Not shown in the figure is a composite type in which the outside air side is made of aluminum, the inside side is made of plastic, and the inside and outside are made of plastic, etc. Airtightness is 2 grade or higher and heat insulation is 2.6 Kcal / m ² · h
The sealing means is applied to the inside and outside of the heat insulating board at the contact portion between the outer periphery of the window forming sash frame having a performance of not more than 0 ° C. and the heat insulating board 17 to improve the air tightness inside and outside and the durability of the heat insulating board. In addition, it is preferable that a sponge-like double-sided airtight tape is additionally treated with a silicone sealant at a portion where deformation and behavior of the skeleton are expected due to aging, and heat insulation and airtightness are expected to be deteriorated.

As for the roof portion, as shown in FIGS. 1 and 3, the basic structure of the roof is constructed by assembling a talc 27 having a predetermined inclination above the girder material 16 provided at the upper end of the pillar 15 by appropriate support. Then, a heat insulating board 28, which is the same as the heat insulating board 17 of the outer wall portion and has a vinyl coated aluminum foil stuck thereon, is stuck on the entire surface while applying sealing means on both sides as described above. A sponge-like double-sided airtight tape 30 is also filled in with silicon 31 while the airtight layer is continuous to a connecting portion between the upper end of the heat insulating board 17 on the outer wall portion and the heat insulating board 28 on the roof portion to perform sealing. Above the heat insulation board 28, a talc 32 is used to hold a gap, and the ground board 3 made of cedar wood or the like.
3 is stretched, and asphalt roofing 34, for example, is provided thereon as a roofing material to form a roof 35. Roof 35
The end surface 36 is closed by the outer wall member 23 similar to the outer wall portion.
The air gap formed by the talc 32 is hermetically communicated with the outer wall ventilation layer 24 at the lower end portion as the roof ventilation layer 19 to form a series of ventilation layers.

As shown in FIG. 4, a ridge ventilation 37 is provided at the abutting portion of the left and right roof members, that is, at the highest position of the roof. That is, an opening 38 is provided in the abutting portion of the roof materials of the left and right roofs 35, and a building base 4 having a sheet metal 40 such as a stainless plate coated on the outside so as to cover the opening 38.
1 is fixed by hitting the roof 35 with a round needle 44 while interposing a lid benz 43 made of polypropylene having a honeycomb-shaped passage 42 between the roof 35 and the outer surface of the roof 35. The end surface of the lid benz 43 on the side of the opening 38 is formed so as to open downward so that the airflow rising from the opening 38 can be smoothly guided into the honeycomb-shaped passage 42 in the lid benz 43, and the lower end side opening 44 Are formed to be inclined in a substantially horizontal direction. In addition, in order to prevent rainwater that blows up on the roof 35 from flowing into the opening 38 at the time of storm, the water return 45 made of sheet metal is provided at the opening end of the roof 35.
To provide. Further, a contract heat insulating board 46 is embedded in the abutting portion of the heat insulating board 28 of the roof portion, and a waterproof airtight tape 47 is attached to the upper surface thereof to perform sealing. In addition, when the area of the roof 35 is large and the permeable air cannot sufficiently dissipate the outer wall ventilation layer 24 in the ridge ventilation section 37, as shown in FIG. 5, the honeycomb-shaped passages 4 in the lid benz 43 attached by screws are provided.
2 may be increased.

In a house constructed as described above, an air duct 50 is arranged as shown in FIGS. 1, 6 and 7 before the flooring material and the inner wall material are stretched. An air conditioner 51 with a heat exchanger is provided in a part of the house, and air having a predetermined temperature is supplied to the first duct 52.
To the living room on the first floor, and the second duct 53 to the living room on the second floor. Moreover, the kitchen 5 is provided by the third duct 54.
5 Then, as shown in FIGS. 6 and 7, the first floor,
The living room on the 2nd floor is provided with an air supply port (+) and an exhaust port (-) on the diagonal line to form an air flow in the direction shown by the arrow to air-condition the entire room, and the air on the 1st floor is the corridor 60. Through the suction port 58 of the air conditioner 51 with a heat exchanger. Further, the air on the second floor passes through the corridor 60, the stairs 61, and is sucked into the suction port 58 of the air conditioner 51 with a heat exchanger as in the living room on the first floor. Further, the air supplied to the kitchen 55 is directly collected through the duct to the air conditioner 51 with a heat exchanger. Further, the fourth duct 62 of the air conditioner 51 with a heat exchanger is opened to the outside to discharge the air, and the fifth duct 63 sucks the air from the outside to recover the waste heat of the temperature and humidity of the exhaust air during ventilation. . The air in the bath 56, the toilet 57, and the drying room 59 is constantly exhausted through the heat exchange device 65 even when the air conditioner 51 with a heat exchanger is stopped around May or October when the outside air is comfortable. Further, as shown in FIGS. 1 and 2, the sixth duct 66 branched from the first duct 52 is connected to the foundation concrete portion 8 under the floor.
Air conditioner 5 with heat exchanger installed on the one side
The seventh duct 67 is provided up to 1. The aluminum duct 66 arranged on the foundation concrete portion 8 under the floor is provided with an appropriate air discharge hole 68 so that the conditioned air is discharged under the floor. In addition, it is convenient to install the heat exchange device 65 at a place communicating with the room between the first floor and the second floor for easy inspection.

Further, the entire basic concrete is used as a heat storage tank to serve as a stable seasonal main heat source with little influence of outside air. In summer, about 16 ° C geothermal heat is used as part of cooling, and in winter about 13 ° C geothermal heat is taken as part of heating. In a normal use method, when the air conditioned under the floor is continuously sent by the sixth duct 66, the air passes through the inside of an unspecified inner wall with the dry condition of the wood and reaches the attic space. . Therefore, the air is drawn into the seventh duct 67 again, returned to the air conditioner 51 with a heat exchanger, and then heat is recovered and then polluted air (air contacting concrete contains radon gas and is sent indoors as it is. The risk of lung cancer is increased if it is released.) It is exhausted as it is and its action is performed without knowing. And, due to this steady continuation, in the summer when the temperature is high, the cooling effect is obtained by the relatively low geothermal heat, and in the winter when the temperature is low, the daily exhaust heat such as solar radiation, lighting, human heat generation, etc. During the daytime, the heat source for heating is continuously supplied to the heat storage tank under the floor. Then, at night, this adverse effect works together with the gradual decrease in room temperature, and the heat storage tank slowly begins to radiate heat.
Thus, even if the outside air temperature fluctuates rapidly, the cycle of heat storage and heat dissipation using the properties of concrete with a very large heat capacity can be conveniently used to finish the indoor space with very little fluctuation.

If the recovery of geothermal heat is attempted to be directly drawn from the underfloor into the room for the purpose of increasing the efficiency of such action, dangerous radon gas will also be drawn into the room. Therefore, a steel duct (not shown) may be placed in the concrete as long as possible to set a route completely isolated from the underfloor air. Then, by sending fresh clean air into it, concrete is transferred from the steel duct to cause a heat exchange phenomenon with the geothermal heat.

Thus, in the summer, the geothermal heat relatively low with respect to the room temperature is taken out almost directly, and in the winter, the geothermal heat relatively high with respect to the outside temperature is taken out by a phenomenon opposite to that in the summer. And the heat storage effect in winter will be dramatically enhanced by this method. The heat taken out according to this principle is contained in the air, which can be introduced into the living space as it is without any problems, so there is no loss and heating and cooling can be realized at a lower running cost.

In the above air conditioning system, in order to perform the above functions, a three-way switching valve or the like is appropriately arranged and switching is automatically performed by the control device, but since these are well known, description thereof will be omitted. As the air duct used in the air conditioning system, various well-known heat-insulating air ducts such as a cylindrical glass wool body reinforced with a spiral wire whose inner and outer circumferences are coated with vinyl can be used.

In the house constructed as described above, the outer wall and the roof are heated to a high temperature by the solar heat during the daytime in summer, and the heat is transferred to the indoor side through the outer wall material and the roof material. Since the outer wall ventilation layer and the roof ventilation layer are present on the indoor side, the air is heated. All of these heated air rises unpowered by the chimney phenomenon or the outside air wind force, and passes through the outer wall ventilation layer and the roof ventilation layer together with the air near the ground drawn from the opening provided at the bottom of the outer wall ventilation layer, and the roof ventilation. It is discharged to the outside through a ridge-ventilated honeycomb-shaped air passage provided at the top of the layer. Most of the heat reaching the room through the outer wall material and the roof material is discharged by this air flow.

The cold heat from the air conditioner in the room is
Although it tries to transfer heat to the outside through the floor, the ceiling, etc., the heat is blocked by a heat insulating board provided all around the circumference of the house, and the heat is prevented from being dissipated. Further, since this heat insulating board is coated with aluminum, it has high airtightness and extremely low thermal conductivity, so that heat transmitted from the outside to the indoor side is minimized. Furthermore, various double seals are applied to the joints of the heat insulation board, air leakage from these parts is prevented, and the end of the heat insulation board is also sealed, so air bubbles inside the heat insulation board are prevented. The outflow of gas trapped inside is also prevented. In addition, since the underfloor on the 1st floor forms a space that is closed to the outside air by the concrete in which the heat insulating material is buried, it not only prevents the heat radiation to the underfloor like the conventional one, but also keeps a constant level throughout the year. Geothermal heat can be taken out, and by installing a heat insulating board on the outer periphery of the rising part of the foundation, the heat insulating effect can be further enhanced, and by combining these, it is possible to air-condition all indoor rooms with a small air conditioner, The operating cost of the air conditioner can be reduced.

On the other hand, in winter, the room temperature rises due to solar heat from windows and the like, and each room has high heat insulation and airtightness as described above, so that the heat circulates in all the rooms, resulting in uneven temperature. In addition to being eliminated, highly efficient air conditioning can be performed. Further, since the cold heat does not transfer from the outer wall to the indoor wall and the temperature unevenness does not occur in the room as described above, there is no dew condensation as in the conventional case, and thus the generation of mold and mites. It is possible to prevent the occurrence of allergic diseases such as asthma and atopic dermatitis in the resident.

Further, since the airtightness of the entire house is increased, the sound from the piano or the acoustic product is hardly transmitted to the next house, and the noise of the outside car or the noise of the next house can be prevented. it can.

Further, the air circulated in the kitchen, bath, toilet, etc. in the house such as the living room is taken in by the air circulated in each room, and the air is sucked directly into the air conditioner together with the odor to be treated. , The bath, toilet, etc. are always in a negative pressure room, and even if the door is opened, only the outside air enters and no strange odor in the room leaks to the outside.

As a result of actually constructing a house having the above structure and measuring the ventilation frequency, the following data were obtained. Airtight floor area 142.13m ³ … Air volume in the attic 83.55m ³ … Air volume under the floor 30.4m ³ …… Total air volume in the attic and under floor (+) 113.95m ³ … Conversion to floor area ∴ 113.95m ³ /2.6m ≒ 43.83m ² … The total clearance equivalent area αA = 65cm ² according to the airtight measurement result ………… The effective total area of the building envelope (+) S = 142.13 + 43 .83 = 185.96 m ² ... Area equivalent to clearance per 1 m ² floor area (/) C = 65 / 185.96≈0.3495 (cm ² / m ² ) Air volume of the entire building 525.05 m ³ According to the measurement results, the fixed flow rate at 50 pa was 229 m ³ / h ∴ Ventilation rate = 229 / 525.05 ≒ 0.436 times / h / 50 pa, which is a representative of the world's energy-saving housing. 1.5 times / h for 2000 houses
It was possible to realize extremely high airtightness even when compared with / 50pa.

Due to the airtightness and the effect of the heat insulating material, the air conditioning of the building of about 60 tsubos is about 4000 kcal / h.
One air conditioner is enough, and according to the measurement result of the house, the room temperature in winter is around 18 ° C, the humidity is 50% inside and outside, the room temperature in summer is around 28 ° C, the humidity is 50-60%, and the temperature and humidity of the outside air change greatly. Nevertheless, it was confirmed that a small air conditioner could maintain stable temperature and humidity almost as set.

[0026]

EFFECTS OF THE INVENTION Since the present invention is constructed and operates as described above, it has extremely good heat insulation and airtightness, and can maintain a uniform temperature throughout the room, including under the floor and inside the indoor wall, and can prevent solar heat, geothermal heat, etc. It is possible to effectively use natural energy and domestic exhaust heat from the interior of the house, it is possible to make an energy-saving house, no condensation occurs due to uneven temperature, and as a result, mold does not occur and mites do not occur. Allergic diseases caused by these can be prevented. In addition, the sound insulation is high and it is possible to prevent sound leakage from the inside and intrusion of sound from the outside, and the living odor inside is finally discharged by the air circulating inside the house, and does not diffuse into the house. In addition, since dust floating in the air in the room is always collected, it can be visually confirmed that the dust is very clean.

Furthermore, since air is supplied from the air conditioner to each room by a low-speed circulating flow, the air conditioning eliminates the discomfort of air conditioning.
Since the house can completely prevent moisture, it can be used for 70 years or 100 years for a long time even in a wooden house, and there is no need to use harmful chemicals such as anti-termite treatment.
In addition, even in a house with poor sunlight conditions, a comfortable living space can be obtained due to the stable geothermal effect throughout the year.
