Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating construction method for buildings.

[0002]

2. Description of the Related Art In a building such as a unit building, for example, a heat insulating material is loaded in a gap between a wall structure of one building unit and a wall structure of the other building unit installed adjacent to each other to enhance heat insulating performance of the entire building. Sometimes.

In JP-A-61-60418, in order to reduce the transport volume of the heat insulating material as described above, the air in the plastic bag containing the heat insulating material is evacuated, thereby reducing the thickness of the heat insulating material during transportation. I am proposing a packing method to do.

By the way, it is necessary to uniformly fill the gaps in the building with the heat insulating material. If a gap still remains after the heat insulating material is loaded, dew will form on the remaining portion of the gap, causing inconveniences such as generation of mold and deterioration of heat insulating performance.

However, the conventional methods for loading the heat insulating material into the gaps between buildings are: (1) inserting the cotton-like heat insulating material, (2) inserting the cotton-like heat insulating material, and (3) spraying the foam heat insulating material. There are things to put in.

[0006]

However, the prior art has the following problems (1) to (6) when the gap to be filled with the heat insulating material becomes narrow. Cotton-like insulation is difficult to cut to fit a narrow gap, and as a result the gap cannot be evenly and completely filled. Further, when the wood of the wooden structure forming the gap becomes thin, it is impossible to fill the new gap caused by this.

With a cotton-like heat insulating material, the tip of a screwdriver or the like pushes it into a narrow gap, but it is difficult to insert it evenly, and it is not possible to confirm whether or not it has reached the back.

In the foamed heat insulating material, bubbles must be prevented from protruding from the gap, and if they are protruded, an extra portion must be cut and removed. Further, on a wall surface or the like, the foaming force may cause the wall to swell.

The method of packing the heat insulating material described in Japanese Patent Laid-Open No. 61-60418 is merely for packing a plurality of heat insulating materials in a compact size at the transportation stage, and at the use stage. Since the heat insulating material is taken out of the bag and used, it does not have a function of uniformly, reliably and easily loading into a narrow gap.

An object of the present invention is to make it possible to easily and uniformly load a heat insulating material into a narrow gap of a building.

[0011]

According to a first aspect of the present invention, in a heat insulating construction method for a building in which a gap in the building is filled with the heat insulating material, the heat insulating material is put in a plastic bag, With the bag thinned by removing air,
After sealing the bag and inserting the thin insulating bag into the gap in the building, open the bag to allow air to be sucked into the bag, and use the heat insulating material to fill the gap with the deformation restoring force. It is designed to be thickened.

The present invention according to claim 2 is the same as the invention according to claim 1, wherein the gap in the building is a gap generated at a joint portion between adjacent building units.

[0013]

According to the present invention described in claim 1,
Has the effect of The evacuated bag with heat insulating material becomes as thin as about 1/10. For this reason, it is possible to easily and securely insert even a narrow gap to the back.

By opening the bag containing the heat insulating material into the gap and then opening the bag, the thickness of the heat insulating material is immediately increased by its deformation restoring force, and the gap is uniformly filled. Therefore,
No gap remains after the heat insulating material is loaded, and there is no dew condensation due to the gap remaining, and thus no mold, and no decrease in heat insulating performance. Particularly in the roof unit, since warm air in the living room easily hits the rear surface of the roof to cause dew condensation, it is significant to uniformly fill the inter-unit gap that causes dew condensation with a heat insulating material.

The heat insulating material whose thickness is restored to fill the gap does not protrude from the gap, and the deformation restoring force of the heat insulating material is considerably smaller than the strength of the wall forming the gap. It does not cause a bulge.

[0016] When the wood of the wooden structure forming the gap becomes thin, the new gap generated by the tree structure is immediately filled by increasing the thickness of the heat insulating material by the remaining capacity of the deformation restoring force.

According to the present invention described in claim 2, the following effects are obtained. In a unit building, a narrow and long gap is created in the entire building at a joint portion between adjacent building units between opposing wall structures, opposing floor structures, or opposing roof structures. The narrow and long gaps that occur throughout the building can be evenly and reliably provided by the heat insulating material.
It can be easily filled and the thermal insulation performance of the entire unit building can be improved.

1 is a schematic view showing an embodiment of the present invention, FIG.
[Fig. 3] is a schematic diagram showing a unit building.

The unit building 10 transports building units such as a living room unit 11 and a roof unit 12 produced in a factory in advance to the site, and installs the living room unit 11 on the foundation 13 (FIG. 2 (A)). It is constructed by installing the roof unit 12 on the above (FIG. 2 (B)). The living room unit 11 includes a floor structure 11A and a wall structure 11B.
It consists of and.

At this time, in the unit building 10, at the joints between the adjacent living room units 11 and 11, between the floor structures 11A and 11A facing each other, and the wall structures 11B and 11 facing each other.
A narrow and long gap is created between B. Further, a narrow and long gap is also formed in the joint portion between the adjacent roof units 12, 12.

In the present embodiment, the above-mentioned gaps are defined by the following (1) to (3)
Insulate by. In addition, the adjacent living room units 11,
A case where heat insulation is applied to the gap 14 between the opposing wall structures 11B and 11B at the joint portion 11 will be described as an example (FIG. 1).

(1) The heat insulating device 21 is put in a plastic bag 22, and the air inside the bag 22 is evacuated by a vacuum suction device 31 or the like to reduce the thickness of the bag 22. The opening of the bag 22 is sealed (FIGS. 1A and 1B).

As the heat insulating material 21, glass wool, rock wool or the like, which is resistant to moisture, is suitable. As the heat insulating material 21, it is possible to use cellulose fiber which is weak against moisture. As the bag 22, a vinyl chloride film or a vinyl chloride sheet can be used.

(2) In the unit building 10, the thin heat-insulating material bag 22 prepared in the above (1) is used to connect the adjacent room units 11 and 11 to each other.
It is inserted into the gap 14 between B and 11B (FIG. 1 (C)).

(3) After the above (2), the bag 22 is opened by tearing or the like to allow air to be sucked into the bag 22, and the heat insulating material 2
1 is thickened so as to fill the gap 14 with this deformation restoring force (FIG. 1 (D)).

The operation of this embodiment will be described below. The thickness of the evacuated insulating bag 22 is reduced to about 1/10. Therefore, even in the narrow gap 14,
Can be inserted securely to the back.

When the bag 22 containing the heat insulating material is loaded into the gap and then opened, the thickness of the heat insulating material 21 is immediately increased by its deformation restoring force, and the gap 14 is uniformly filled. Therefore, the gap 14 does not remain after the heat insulating material 21 is loaded, and the dew condensation, the generation of mold, and the deterioration of the heat insulating performance due to the remaining gap 14 do not occur. In particular, in the roof unit 12, warm air in the living room easily hits the rear surface of the roof to cause dew condensation, so that it is significant to uniformly fill the inter-unit gap 14 that causes dew condensation with the heat insulating material 21.

The heat insulating material 21 whose thickness is restored to fill the gap 14 does not protrude from the gap 14, and the deformation restoring force of the heat insulating material 21 depends on the strength of the wall forming the gap 14. It is quite small and does not cause wall blistering.

When the wood of the wooden structure forming the gap 14 becomes thin, a new gap created by this is to be immediately filled by thickening the heat insulating material 21 with the remaining capacity of the deformation restoring force. .

In the unit building 10, at the joints of the adjacent building units 11 and 11, between the opposing wall structures 11B and 11B, the opposing floor structures 11A and 11A.
Roof structure (or roof unit 1)
2, 12), a narrow, long gap 14 is created throughout the building. The narrow and long gaps 14 generated in the entire building can be uniformly, surely, and easily filled with the heat insulating material 21 by the above items, and the heat insulating performance of the entire unit building can be improved.

The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration of the present invention is not limited to this embodiment, and changes in design within the scope not departing from the gist of the present invention can be made. Even if it exists, it is included in the present invention. For example, the present invention is not limited to buildings by the unit construction method, but can be widely applied to general buildings. Further, the present invention is not limited to a building made of a wooden structure but can be applied to a building made of a steel frame structure.
