Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulation method for a ceiling portion of a wooden house used in a building of a general house.
The present invention intends to provide a heat insulating method for a ceiling portion of a wooden house that can obtain a ceiling having excellent heat insulating properties.

[0002]

2. Description of the Related Art As a conventional method for insulating a ceiling of a wooden house used in a building of a general house, in order to improve the heat insulating property of the ceiling, as shown in FIG. In general, the fiber type heat insulating mat 13 is laid to improve the heat insulating property. 14 is a lumber, 15 is a eaves girder, 16 is a beam, and 17 is a lighting device (downlight) built in the ceiling.

Further, as shown in FIG. 6, there is one in which a fibrous granular heat insulating material 23 is blown into the ceiling 22 side of the ceiling 21 to improve the heat insulating property. 24 is a lumber, 25 is an eaves girder, 26 is a beam, and 27 is a lighting fixture built in the ceiling.

Further, as shown in FIG. 7, there is one in which a heat insulating panel 33 is attached to the inner surface side of the roof 31 via a receiving member 32 in an inclined manner to improve the heat insulating property.

Similarly, in the example of FIG. 8, the heat insulating material 4 is directly applied to the lower ends of the roof 41 and the rafter 42 or after the base material 43 is applied.
4 is to be sprayed.

In the example of FIG. 9, a heat insulating panel 54 is mounted and fixed on the eaves girder 52 above the ceiling 51 and the upper ends of the beams 53.

[0007]

However, each of the conventional heat insulation methods for the ceiling of the heat-insulated wooden house has the following problems.

In the example of FIG. 5, it is difficult to maintain the airtightness of the connection portion of the heat insulating mat 13, and the treatment of the lighting fixture 17 portion built in the ceiling is particularly troublesome.

In the example of FIG. 6, since the portion of the luminaire 27 built in the ceiling 21 generates heat, it is necessary to provide a space in the portion, which impairs the heat insulating property. It takes a lot of time and labor for the preliminary work to install the. In addition, it is necessary to form a moisture-proof layer 28 between the ceiling 21 and the ceiling 21 by a moisture-proof sheet or the like when the heat insulating material 23 is sprayed.

In the example of FIG. 7, since the heat insulating panel 33 is attached to the inner surface side of the roof 31 through the receiving member 32 in a sloped manner, it takes too much time and labor for construction. And it is difficult to get ventilation in the attic. Further, since the volume up to the attic becomes the heating and cooling volume, the cooling and heating load increases.
Furthermore, since the heating panel 33 is used, it is still difficult to maintain the airtightness of the connection portion.

In the example shown in FIG. 8, the heat insulating material 44 is sprayed directly on the lower ends of the roof 41 and the rafter 42 or after the base material 43 is applied, and it is difficult to obtain ventilation in the attic. Further, since the volume up to the attic becomes the heating and cooling volume, the cooling and heating load increases.

In the example of FIG. 9, the girder 5 above the ceiling 51 is used.
The heat insulating panel 54 is mounted and fixed on the upper end of the beam 2 and the beam 53, and it is also difficult to maintain the airtightness of the connecting portion of the heat insulating panel 54.

The present invention is intended to solve the above-mentioned drawbacks of the conventional heat insulation method for the ceiling of the wooden house, and provides a heat-insulating ceiling which does not impair the moisture-proof property, airtightness, and heat-insulating property even when used for a long period of time. In addition, it is possible to provide a heat insulating construction method for the ceiling portion of the wooden house, which can be done with a simple structure, is easy to construct, and can obtain a cheap and high-quality ceiling.

[0014]

That is, according to the heat insulating construction method for a ceiling portion of a wooden house of the present invention, a base plate is provided on the upper part of the girder and the beam on the ceiling, and a heat insulating layer is provided on the surface thereof, and on the lower surface of the base plate. It is characterized by being formed by spraying and by spraying, blowing, and pouring on the upper surface of the base plate.

In the heat insulating construction method for the ceiling of the wooden house of the present invention, the base plate is selected from a plywood plate, a plastic plate or sheet, a corrugated plate, a wood-based material, a fiber-based or pulp-based board, and a mesh plate of a predetermined mesh. It is also characterized by that.

Further, in the heat insulation method for the ceiling portion of the wooden house of the present invention, the heat insulation layer is formed by spraying / injecting urethane foam, spraying / injecting cellulose fiber, spraying / injecting rock wool / glass wool, polystyrene beads, and styrene foam. This is also one of the features.

[0017]

As described above, the heat insulation method for the ceiling portion of the wooden house of the present invention is such that the foundation plate is provided on the girders on the ceiling and the upper ends of the beams.
Since a heat insulating layer is formed on the surface by spraying on the lower surface of the base plate and by spraying, blowing, and pouring on the upper surface of the base plate, a seamless heat insulating layer can be obtained without complicated shapes. It is possible to provide a heat insulating structure for the ceiling part of the wooden house with good airtightness.

Further, it is possible to provide a heat insulating structure for the ceiling portion of the wooden house, which does not require heat insulating treatment or safety measures for a heat generating portion such as a lighting fixture, has good workability, and is good in terms of safety.

Further, any ventilation structure such as eaves ventilation, attic ventilation, and ridge ventilation can be adopted, and it is possible to provide a heat insulating structure for the ceiling of a wooden house with a wide range of application.

In summary, the heat insulation construction method for the ceiling portion of the wooden house of the present invention is such that the eaves girders and beams are wrapped with a heat insulation material,
Since the heat insulation layer is formed on the outside of the eaves girders and beams, a further heat insulation effect can be obtained, and in particular, the heat accumulation of wood that causes "hot flashes" in summer can be avoided. In addition, it has a three-layer structure consisting of a ceiling layer, a heat insulating layer, and a roof layer, so it is particularly effective for the summer heat protection method. Of course, even in winter heating, since the volume is small, thermal efficiency is good and energy can be saved.
