Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat insulating material to be installed under the ceiling or under the floor of a building.

[0002]

[Prior art]

 As a conventional method for constructing a heat insulating material, there is generally a method in which a heat insulating material such as glass wool formed into a mat or a plate is cut into an appropriate size and used. However, since there are field edges, fishing trees, joists, etc. installed under the ceiling and under the floor, if a mat-shaped or plate-shaped heat insulating material is laid, the heat insulating material will not be flexible at all. There was a problem that a gap was created around fishing rods and joists and the heat insulation effect was reduced. Therefore, conventionally, the following methods have been devised. First, as a first conventional example, as disclosed in, for example, Japanese Patent Publication No. 60-27335, there is a method in which a fibrous heat insulating material crushed into small pieces is spread over the ceiling. In the conventional example, a small heat insulating material is blown or compressed air is supplied to the back of the ceiling using a conduit and is blown into a required place without a gap to form a heat insulating material layer having a constant thickness. Next, as a second conventional example, there is a method of filling a small heat insulating material between two sheets, as disclosed in, for example, JP-A-57-180735. In the conventional example, first, a flexible underlayment sheet is arranged along an uneven surface such as joists, and a small heat insulating material is dispersed and filled over the entire area of the flexible underlayment sheet. The top sheet is covered with a flat sheet of overlay sheet. Next, as a third conventional example, there is a method of filling a small heat insulating material in a bag made of a flexible material, as disclosed in, for example, Japanese Patent Laid-Open No. 54-117114. In this conventional example, first, a bag is arranged on the ceiling, and a conduit is used to supply the heat insulating material in the form of small pieces. Next, as a fourth conventional example, as shown in, for example, Japanese Utility Model Laid-Open No. 1-154705, a heat insulating material having a predetermined shape is previously sealed between two long sheets. In the conventional example, a plate-shaped heat insulating material is formed into a shape corresponding to a standardized interval of joists, and this is sealed between long sheets at an interval corresponding to the width of joists to form the heat insulating material. At the time of construction, it is laid so that the plate-shaped heat insulating material is located between the joists.

[0003]

[Problems to be solved by the device]

 According to the above-mentioned first to third conventional examples, the heat insulating effect is high without forming a gap around the edge of the field, fishing trees, joists, etc. Since it is a method of pumping together with the above, there is a problem that fibers constituting the heat insulating material are scattered during the construction work. Further, according to the fourth conventional example, since the plate-shaped heat insulating material is sealed in the sheet in advance, there is no problem that the fibers constituting the heat insulating material scatter, but the intervals between joists are standardized. There is a problem that it can only be used in the open places, and it cannot be used in buildings such as Western-style rooms and Japanese-style rooms where the intervals between the joists vary. Moreover, since the heat insulating material is not sealed in the space corresponding to the width of the joists, there is a problem that there is no heat insulating effect at the joist locations. Therefore, an object of the present invention is to provide a heat insulating material that can be applied without scattering fibers constituting the heat insulating material during work and without forming a gap around a field edge, fishing tree, joist, or the like. .

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the heat insulating material of the present invention encloses a small heat insulating material with a covering material, leaving a moving space inside, and at least the covering material on the side of the space to be insulated is made of a flexible material. And a partition for partitioning the internal space formed by the coating material into predetermined spaces.

In the heat insulating material, the covering material is composed of two long sheets, the long sheet on the side of the heat-insulated space is a moisture-proof sheet, and the other long sheet is provided with a large number of vent holes. It is preferable to use a breathable sheet.

[0006]

[Action]

 According to the present invention, since the heat insulating material is sealed in the covering material, fibers constituting the heat insulating material do not scatter in the ceiling or under the floor during work. Further, in the present invention, since a small lump-shaped material is used as the heat insulating material to leave a moving space inside and the covering material on the side of the heat insulating space is made of a flexible material, it is possible to surround the field edge, fishing tree, joist, etc. It can be laid without creating a gap and has a high heat insulation effect. Further, according to the present invention, by partitioning the inside of the covering material into predetermined spaces by partitions, it is possible to prevent the enclosed small heat insulating material from moving too much and causing uneven density due to unevenness, and to make it uniform. A good heat insulating effect can be obtained. Further, in the present invention, the covering material on the side opposite to the insulated space side is made of a breathable long sheet having a large number of ventilation holes, so that the heat insulating material can be packed in a compressed manner, which makes After that, the ventilation holes allow the moisture remaining in the heat insulating material to be discharged, and the heat insulating performance can be prevented from deteriorating due to the use of a moisture-proof sheet on the insulated space side.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view of a heat insulating material according to this embodiment, FIG. 2 is a sectional view taken along the line II-II of FIG. 1, and FIG. 3 is an explanatory view showing a state where the heat insulating material according to this embodiment is applied to a ceiling. In the figure, reference numeral 1 denotes a heat insulating material. This heat insulating material 1 is a small heat insulating material made of a fibrous material between a first covering material 2 and a second covering material 3 which are fused and are formed into a bag shape. The material 4 is sealed.

Here, the first coating material 2 is a long length made of a flexible material having flexibility and moisture resistance, such as a thermoplastic synthetic resin sheet of polyethylene or the like, an aluminum vapor deposition synthetic resin sheet, or a synthetic resin film-coated aluminum foil. It is preferable to use a sheet. Further, the second covering material 3 may be the same material as the first covering material 2 or may be a material having no flexibility, but in this embodiment, the handling at the time of construction is facilitated. Therefore, a breathable long sheet made of the same material as the first covering material 2 and provided with a large number of breathable holes 5 on the surface thereof was used.

As the heat insulating material 4, inorganic fibers such as glass wool and rock wool that have been previously crushed into small pieces of 20 to 30 mm by a crusher are used.

In the figure, reference numeral 6 denotes a partition, which is formed by folding the first coating material 2 toward the second coating material 3 side and fusion-bonding it to the second coating material 3. There is. And as shown in the figure, a plurality of partitions 6 are provided at predetermined intervals in the longitudinal direction of the heat insulating material 1. In the figure, 7 indicates the ceiling and 8 indicates the field.

The method of manufacturing the heat insulating material according to the present embodiment will be described. After the heat insulating material 4 in the form of small lumps is sandwiched between the first coating 2 and the second coating 3 by a crusher in advance, the heat insulating material is heat-insulated. The method of fusion-bonding the side portion of the material 1 and the partition 6 is simple and suitable for continuous production.

Next, a case where the heat insulating material 1 according to the present embodiment is applied to the ceiling will be described. In this case, as shown in FIG. 3, the heat insulating material 1 is applied so that the first covering material 2 is on the indoor side which is the space to be thermally insulated. At this time, the first covering material 2 on the field edge 8 is pushed up, and the heat insulating material 4 inside forms a concave portion along the field edge 8 so that between the heat insulating material 1 and the stud 8. There is no gap in. Therefore, the construction can be performed without considering the position of the stud 8. In addition, you may fix the heat insulating material 1 and the field edge 8 with a tacker etc. as needed.

As described above, since the installed heat insulating material 1 uses the first covering material 2 as a moisture-proof sheet, it prevents moisture and humidity from the inside of the room from entering the heat insulating material 4. Further, it is possible to prevent the permeation of water from the outdoor side. Further, since the second covering material 3 is air permeable, the moisture in the heat insulating material 1 can be released, and the retention of the moisture in the heat insulating material 1 can be prevented.

It should be noted that, although the case where the construction is applied to the ceiling is explained in the present embodiment, it goes without saying that the heat insulating material according to the present invention can also be used for construction under the floor and the like. Further, in the present embodiment, the description has been given by using the two long sheets as the covering material, but it may be configured by bending one sheet. It is not limited to long ones.

[0015]

[Effect of device]

 As is clear from the above description, according to the heat insulating material of the present invention, even if there is unevenness on the heat insulating material construction surface due to wild edges, fishing trees, joists, etc., it can be laid without creating a gap The fiber is not scattered during the work. In addition, the present invention is capable of obtaining a uniform heat insulating effect because the enclosed heat insulating material is less likely to be biased, and can also prevent deterioration of heat insulating performance due to moisture.
