DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a heat-insulating structure capable of improving the heat-insulating effect of the outer wall or roofing material of the building.

[0002]

2. Description of the Related Art In recent years, airtightness of a building has been promoted by cooling and heating of the building, and dew condensation has occurred on the outer wall and the like during the cooling and heating operation due to a difference in temperature between the inside and outside of the outside wall. , Wood decay tends to accelerate. On the other hand, in order to suppress energy consumption during cooling and heating, there is a demand for an improved heat insulating structure for outer walls and roofing materials.

For this reason, it has been proposed to provide an air convection layer between the outer wall of the building and the heat insulating material to prevent dew condensation on the outer wall and to suppress the energy consumption of the cooling and heating device (for example, Japanese Utility Model Application Laid-Open No. 61-61). 37307 publication). The building of this structure has an outer wall made of a finishing material attached at intervals so as to form an air layer in the heat insulating material, and the air in the air layer flows in from an air inlet provided below the outer wall to form the outer wall. Natural ventilation means or forced ventilation means flowing out of an air outlet provided above or in the attic.

[0004] However, this prior art heat insulating structure building is
Since there is only one layer of air in the outer wall, the air in the air layer is warmed through the outer wall, and thus the air in this air layer sufficiently blocks the temperature difference between the outer wall and the insulation between the inside and outside. In this case, the heat-insulating effect could not be improved. In addition, in this conventional heat-insulating structure, the convection air is only guided to the attic and discharged from the attic to the outside, so that the roof itself is easily affected by the outside air, which affects the indoor temperature. Was likely to be provided.

[0005] For this reason, a heat-insulating structure building which is assembled so as to form two air layers between an outer wall and a heat insulating material inside the outer wall has recently been proposed (Japanese Patent Laid-Open No. 4-16969).
No. 37). Since this structural building can effectively shut off the heat from the outside air to the room due to the temperature gradient of the air in the inner and outer air layers, a large heat insulating effect is expected as compared to an insulated structure building having only a single air layer. be able to.

[0006] However, the heat insulating structure having a double air layer according to the prior art is used when assembling the inner and outer walls so that the double air layer is formed between the heat insulating material and the intermediate wall and between the intermediate wall and the outer wall. Since it is constructed and assembled on site, there is a drawback that the assembly of the building is complicated and the construction cost is high.

In this prior art, the air in the double air layer is mixed in the attic and flows out of the roof or returns to the air duct in the partition wall in the building. The air in the outer air layer, which is easily heated or cooled by the radiant heat or cold air, mixes with the air in the inner air layer, which is not easily affected by the outside air temperature, in the attic, and the heat is easily trapped in the roof, and the room close to the roof If the heat-insulating action of the air-conditioning device is reduced, and such air is returned to the indoor air duct, the outside air temperature is undesirably introduced into the room.

Further, in the building having this double air layer, the air in the outer wall is merely guided to the roof, and therefore, similarly to the prior art, the roof material reduces the outside air temperature by the air passing through the outer wall. It is susceptible to the influence, which may adversely affect the indoor temperature.

A tile or the like (not shown) may be provided directly on the roof plate 32, but in order to effectively prevent water leakage, a thin waterproof layer is provided on the roof plate 32 and a tile or the like is provided thereon. Is preferred.

As shown in FIG. 1, the building 10 further includes floor panels 18 surrounding the living rooms 16, 24 on the first and second floors.
And an inner wall 38 and an outer wall 40 provided between the floor panel 26 and the ceiling panel 30, and a heat insulating panel 42 is provided between the inner wall 38 and the outer wall 40.

As shown in FIG. 4, the inner wall 38 is composed of a lath base material 52 and an internal finishing material 54. In the illustrated embodiment, the inner wall 38 is fixed to the column 20 with the lath base material 52 facing the heat insulating panel 42 so as to wrap the column 20 so that the column 20 is not exposed to the room. Accordingly, the illustrated building 10 is shown to have a large wall structure (Western structure). The internal finishing material 54 can be made of a suitable material such as a cloth, a gypsum board, or a flexible board.

On the other hand, as shown in FIGS. 1 to 4, the outer wall 40 is an integrated paneled wall material 4 fixed to the column 20 so as to be attached to the heat insulating panel 42.
The outer surface of the wall material 41 is provided with a makeup (not shown). The wall material 41 is made of a suitable heat-insulating material such as wood, compressed wood, non-asbestos, calcium silicate mortar, sawdust mortar, cement and the like.

As shown in FIGS. 1 to 5, a building 10 according to the present invention has a multiple air convection layer provided independently of each other in a panel-shaped wall member 41. The heavy air convection layers 56 and 58, the air stagnation layer 60 provided between the double air convection layers 56 and 58 in the panel-shaped wall member 41, and the air in the double air convection layers 56 and 58. And an outer wall ventilation means 62 for ventilating the air.

Details of the outer wall 40 are shown in FIGS.
Outer air convection layer 56 of double air convection layers 56 and 58
Are a number of vertical through-hole air-flow ducts 64 provided vertically through the outer wall 40 outside the wall material 41 in the thickness direction.
And the inner air convection layer 58 is
2 are closed by asphalt felt (roofing) 50 constituting the outer surface of
Is formed on the inner surface in the thickness direction of the wall material 41 of the outer wall 40 so as to form the vertical groove 68. Adjacent flutes 6
8 between the outer wall 40 and the heat insulating panel 4
It has the function of rafters between the two, so that there is no need to attach rafters during assembly, making assembly easier.

Further, as shown in FIG. 2, the air stagnation layer 60 in the outer wall 40 has a large number of air trapping holes provided between the inner and outer air convection layers 56 and 58 in the wall material 41 of the outer wall 40. Consists of 70. The air stagnation layer 60 is made up of air trapped and retained in the air confinement holes 70, and therefore does not cause convection.

As shown in FIGS. 1 and 5, the outer wall ventilation means 62 opens the lower ends of the air flow-through ducts 64 and 66 to the ground so that air flows into the double air convection layers 56 and 58. The air inlets 72, 74 formed so as to allow air to flow in from the lower end of the wall material 41 of the outer wall 40, and the outside that allows air in the outer air convection layer 56 to flow directly to the outside from the upper end of the wall material 41 of the outer wall 40. It comprises an air outlet 76 (see FIG. 1) and internal air outlets 78A, 78B through which air in the inner air convection layer 58 flows out through the attic space 80. Therefore, it should be noted that the outer air in these outer air convection layers 56 that is most affected by the outside air temperature is not guided into the attic space 80, and thus this outer air is There is no mixing with the internal air in the internal air convection layer 58 in the attic space 80.

As shown in FIG. 16, the external air outlet 76 is preferably closed by a grid-like rain-blocking member 77 through which rain does not flow in from the outside but air can flow out from the inside to the outside. However, if the blindfold 34 has a function of sufficiently removing rain, the lattice-shaped rain shield 77 can be omitted.

The ventilating means 62 for the outer wall further includes fans 82, 84 with closing plates for forcibly discharging air from the internal air outlets 78A, 78B. In the embodiment shown, one fan 82 is attached to the internal air outlet 78A of the eaves underplate 36, and the other fan 84 is attached to the internal air outlet 78B of the ridge ventilation hood 33 of the shingle 32. I have. In FIG. 1, reference numeral 86 denotes an eave attached to an outer wall portion between the first floor and the second floor.

As shown in FIG. 17, the fan 82A with a closing plate is mounted on the inner surface of the eaves lower plate 36 in alignment with its opening and mounted on the outer surface of the eaves lower plate 36 in alignment with this opening. The opening 82B can be freely opened and closed, and the fan 82A and the opening 82B are controlled independently as described later. In addition, the fan 84 with a closing plate is similarly comprised from the fan 84A and the stick 84B.

The fans 82 and 84 are controlled, for example, by an optical sensor (not shown) that receives external light and generates a fan drive command so that the fans 82 and 84 are operated during the daytime in summer, stopped at night, and constantly stopped in winter. However, of course, in addition to or instead of the drive by the light control, the drive may be performed by manual control. In addition, the closing plates of the scrapers 82B and 84B are controlled so as to open in summer and close in winter, but the closing plates may be manually opened and closed.

As described above, the outer wall 40 of the heat-insulating structure building 10
With the double air convection layers 56 and 58 inside, even if the outer air flowing in the outer air convection layer 56 is heated by the radiant heat received by the outer wall 40, it further has the air convection layer 58 inside, The inside air, which is not affected by the outside air temperature by flowing in the inside air convection layer 58, has an action of shielding the outside temperature. In particular, in summer, the outside air in the outside air convection layer 58 has the function of absorbing this radiant heat on the outer surface of the outer wall 40 and discharging it to the outside by natural convection, so that the outer air having the function of cooling the outer wall 40 is provided. In addition, the heat shielding effect of the inner air convection layer 58 is promoted, and the heat insulating effect of the outer wall 40 is significantly improved. In winter, the air convection layer 58
The outside air in the inside is cooled by cold air absorbed through the outer surface of the outer wall 40, and the outside air having absorbed the cool air descends backward in the air convection layer 58 and is discharged from the air inlet 72. Therefore, the heat insulating effect of the inner air convection layer 58 can be promoted.

The air stagnation layer 60 in which the air is trapped and stays between the inner and outer air convection layers 56 and 58 has a thermal insulation function by thermally shutting off the space between the inner and outer air convection layers 56 and 58. At the same time, the outside air which flows through the outer air convection layer 56 and is affected by the outside air temperature is prevented from adversely affecting the convection air flowing through the inside air convection layer 58, and the outer wall 4
0 can be further improved.

As described above, the outer wall ventilation means 62 is provided with the air convection layer 56 outside the multiple air convection layers 56 and 58.
The inside air does not flow directly to the outside from the outside air outlet 76 at the upper end of the outer wall 40 and is introduced into the attic space 80, and only the air in the inside air convection layer 58 is inside the attic space 80. As a result, the air in the external air convection layer 56 that is affected by the outside air temperature does not mix with the air in the internal air convection layer 58, and thus the attic space 80 can be affected by the outside air temperature. Absent. Therefore, the room near the attic is less affected by the outside air temperature, and a comfortable living space can be obtained.

Further, as described above, the fans 82A and 84A are operated as necessary in summer to force the air in the inner air convection layer 58 to circulate, and in winter, the fans 82A and 84A By stopping the operation of 84A and, if necessary, closing the closing plates of the rags 82B and 84B, the air outlet 78 can be closed to stop the ventilation action.
Therefore, in winter, the inside air convection layer 58 keeps the air inside, and can shut off the warm air and the cool air inside and outside of each other, thereby maintaining the indoor warming action. Of course, in winter, the closing plate may be kept open, and only the driving of the fans 82A and 84A may be stopped. Incidentally, the ventilation means may be constituted only by a bobble that can be opened and closed by a motor without these fans 82A and 84A.

In particular, the daytime temperature of the attic in the summer rises to a temperature of 40 ° C. or higher, which is considerably higher than the outside air temperature due to the rising air current and the direct radiant heat to the roof. Fans 82A, 84A of internal air outlets 78A, 78B of ventilation means 62
Is operated to allow the outside air to flow in, and relatively cool air passing through the inner air convection layer 58 which is not particularly subjected to radiant heat is forcibly discharged through the internal air outlet 78B of the roof ridge ventilation hood 33. At the time, since the heat in the attic is dissipated, it has a function of preventing radiant heat from being trapped indoors.

Even if the fans 82A and 84A of the ventilation means 62 are not operating during the summer night, cool night air flows into the air convection layers 56 and 58 due to natural convection, and cools and cools. Is performed, the cool air is discharged into the room with the rise in the daytime temperature, thereby preventing the room temperature from rising.

Further, the moisture that tends to condense on the outer surface of the inner wall 38 due to the operation of the cooler or the like is removed from the moisture-permeable heat insulating panel 4.
2 and is carried out by the air rising in the inner air convection layer 58 and discharged to the outside. Therefore, it is possible to effectively prevent the building material from decay due to moisture.

As already described, the fans 82A and 84A
Stops driving in winter and closes plates 82B, 84B
Is also closed, so that the outer and inner air convection layers 5
6, 58 have a function of buffering the temperature difference between the inside and outside by keeping the air trapped, so that the indoor temperature is not released to the outside, so that the heating cost can be reduced and dew condensation occurs. Since there is no such phenomenon, deterioration of the inner and outer wall materials can be prevented beforehand.

A modification of the present invention is shown in FIGS.
In this modification, a part of the air in the internal air convection layer 58 is guided into the attic space 80 through the space 94 between the first floor and the second floor and the partition wall 88 in the second floor living room 24 and the like. It is substantially the same as the embodiment of FIGS. 1 to 4 except that it has an air guiding means 90 and that the pillar 20 is a true wall structure exposed in the living rooms 16 and 24. The air guiding means 90 is composed of a plurality of air flow-through ducts 92 penetrating through a partition wall 88 provided in the second-floor room 24, the lower end opening of which communicates with the space 94 behind the ceiling of the first-floor room 16, and The opening communicates with the attic space 80.

In the building according to this modification, a part of the air in the inner air convection layer 58 enters the space 94 above the ceiling, passes through the air flow duct 92 in the partition wall 88 of the second-floor living room 24, and passes through the attic. After entering the space 80, the air convection layer 58 inside
Rises as it is and merges with other air entering the attic space 80.
