2. Description of the Related Art In recent years, the heat insulation method in wooden construction has come to provide outer heat insulation in addition to inner heat insulation in order to obtain a further heat insulation effect. Generally, when a heat insulating material is attached to a wall, a moisture-proof sheet is attached around the heat insulating material to ensure airtightness as an essential step for maintaining the heat insulating effect.

In the conventional inner insulation method, a moisture-proof sheet is attached between a heat insulating material and a wall, pillar or the like to which the heat insulating material is attached, but when an outer heat insulating material is attached in addition to the inner heat insulating material, it is separately provided. It was also considered to attach a moisture-proof sheet. However, in this case, there is no particular change in the effect of maintaining the airtightness even though the extra material cost is increased, so that it is not carried out.

[0004]

Therefore, it is being studied in the direction of performing construction with one moisture-proof sheet. However, there are various building materials such as beams and receiving trees between the inner heat insulating material and the outer heat insulating material.

In this state, as shown in FIG. 3C, the plaster board 11 is applied to the beam 1 from the indoor side of the beam 1 via the indoor portion 22 of the moisture-proof sheet 2 to fix the nail 1
Fix with 2 and 13.

Then, the indoor portion 22 of the moisture-proof sheet hanging to the outdoor side is rolled up and returned to the indoor side again.
Make sure it hangs as shown in D. In this state, as shown in FIG. 4A, the wooden fixing member 15 is fixed to the plaster board 11 at a position below the auxiliary heat insulating material 8 from the indoor side through the moisture-proof sheet.

Further, as shown in FIG. 4B, the indoor side of the moisture-proof sheet 2 is pulled horizontally with the fixing member 15 as a fulcrum, and in that state, it is positioned below the moisture-proof sheet 2 as shown in FIG. 5A. The ceiling plate 16 is attached to the above , is attached to other appropriate structural material (not shown) of the house, and is fixed to the fixing member 15 by the nail 18 to maintain the ceiling plate horizontally.

In this state, as shown in FIG. 5B , glass wool is sprayed onto the moisture-proof sheet 2 in the direction of the beam 1, the receiving tree 3, the auxiliary heat insulating material 8 and the like from the indoor side and attached as the inner heat insulating material 14. After that, the outer heat insulating material 17 is attached to the plywood 5 from the outdoor side through the outdoor portion 21 of the moisture-proof sheet 2 by a known method.

By the above steps, the airtight construction structure in the hybrid insulation method for wooden construction is completed. In addition,
In the method according to the above-described embodiment, the outdoor portion 21 that hangs on the outdoor side of the moisture-proof sheet 2 is rolled up in FIG. The indoor portion 22 that hangs down on the indoor side may be rolled up so as to hang down from the top of the beam 1 to the outdoor side.

In this case, the plaster board 11
After being nailed to the beam 1 from the indoor side, the indoor portion 22 of the moisture-proof sheet, which hangs on the outdoor side, is rolled up again so that the plywood hangs from the indoor side to the indoor side. Then, the auxiliary heat insulating material 8 is fixed to the receiving tree 3 from below via the central portion of the moisture-proof sheet 2 with nails. Beam 1 in this state
The plywood or the like is applied to the beam 1 from the outdoor side through the outdoor portion 21 of the moisture-proof sheet 2 and fixed with nails. Then, the outdoor portion 21 of the moisture-proof sheet that has hung down to the indoor side is rolled up again so as to hang down to the outdoor side of the plywood. The following steps are the same as those in the above embodiment.

The airtight structure in the hybrid insulation method constructed by the above method is summarized as follows.
That is, the central portion of the moisture-proof sheet 2 is fixed to the lower side of the beam 1 of the wooden construction. An auxiliary heat insulating material 8 is fixed to the lower portion of the beam 1 via the central portion of the moisture-proof sheet.

A plaster board 11 is fixed to the inside of the beam 1 through the inside of the auxiliary heat insulating material. Further, an inner heat insulating material 14 is fixed to the beam through an indoor portion of a moisture-proof sheet hanging from the plaster board 11 toward the indoor side.

Further, a plywood 5 is fixed to the outdoor side of the beam through the outdoor portion of the auxiliary heat insulating material.
An outer heat insulating material 17 is attached to the plywood through an outdoor portion of a moisture-proof sheet that hangs from above to the outdoor side, and a ceiling board 16 is fixed below the inner heat insulating material 14.

[0025]

As described above, in carrying out the airtight construction on the inner heat insulating material of the wall portion of the wooden construction and the heat insulating material in the present invention, first, the central portion of the moisture-proof sheet is fixed to the lower part of the beam, and then both sides thereof are fixed. After the indoor and outdoor parts are hung, after each step of outdoor plywood installation, indoor plaster boat installation, indoor inner insulation material installation, outdoor outer insulation material installation Since the interior and outdoor parts are rolled up so that they do not interfere with the work of fixing the newly installed member, it is possible to perform airtight construction in the hybrid insulation method with a single moisture-proof sheet.

Further, after mounting the plywood on the outdoor side, the indoor portion of the moisture-proof sheet is rolled up and the auxiliary heat insulating material is attached under the beam, and then the plaster board is attached on the indoor side and the indoor side of the moisture-proof sheet is again attached. Since it is rolled up indoors so that it hangs down, it is possible to install auxiliary insulation.

Since the ceiling board is attached below the inner heat insulating material after the outer heat insulating material is attached, the inner heat insulating material and the outer heat insulating material are attached by the method of the present invention from the upper side to the lower side of the ceiling board. It became possible to carry out hybrid insulation over a wide area.

Further, in the hybrid heat insulating structure of the wall portion of the wooden construction according to the present invention, the beam, the plaster board on the indoor side, the inner heat insulating material, the plywood on the outdoor side, and the outer heat insulating material are sequentially arranged. Since a moisture-proof sheet is provided so that it can be sewn, installation work has become possible.

Further, since the auxiliary heat insulating material is attached to the lower part of the beam, the heat insulating effect is increased. Moreover, since the ceiling board is attached under the inner heat insulating material, the airtightness between the upper and lower floors, which is usually difficult, is significantly improved.
