Description

[Technical field]

[0001] The present invention relates to a method for manufacturing a set of insulation material and a building filled with insulation material. [Background technology]

[0002] Increasing the thermal insulation of buildings is important for realizing a comfortable indoor environment and reducing energy consumption for heating and cooling. For this reason, thermal insulation materials are often provided in the walls, foundations, ceilings, etc. of buildings.

[0003] In general, the insulation material is processed into a plate shape of a predetermined size in advance so that it can be filled between the structural members of a building. On the other hand, the size of the space into which the insulation material is filled varies. For example, in a wooden house with a shaku module, the space between the pillars and the studs is about 395 mm, and the space between the studs is about 430 mm. Here, it is not desirable to compress and fill insulation material having a size for filling between the studs and between the pillars and the studs that differ in size by 35 mm, because this reduces the insulation performance. For this reason, insulation materials having dimensions according to each filling location have been manufactured and supplied to the construction site in the past. Alternatively, insulation materials having large dimensions have been cut at the construction site, and the cut insulation materials have been filled into smaller spaces. For example, Patent Document 1 discloses that the insulation material is easily cut by forming multiple grooves in the insulation material. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 11-029998 Summary of the Invention [Problem to be solved by the invention]

[0005] On the other hand, when using insulation materials with various dimensions, the number of types of insulation materials used at construction sites increases. This requires securing a larger storage space for the insulation materials. In addition, when cutting the insulation materials, the cumbersome task of cutting the insulation materials is required. Furthermore, the cut pieces must be disposed of as industrial waste, which creates an economic burden.

[0006] The present invention aims to facilitate the application of insulation to various filled spaces in buildings. [Means for solving the problem]

[0007] The set of insulating materials according to one embodiment includes: A set of insulation materials to be filled into a building, a first insulation having a first width; a second insulation having a second width that is less than or equal to one-third of the first width; Includes. Effect of the Invention

[0008] It is possible to easily install insulation materials in various filled spaces of buildings. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are essential to the invention. Two or more features among the multiple features described in the embodiments may be arbitrarily combined. In addition, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0011] The set of insulating materials according to one embodiment includes a first insulating material and a second insulating material. FIG. 1 shows a schematic diagram of a first insulating material 100 and a second insulating material 150. As shown in FIG. 1, the type of the first insulating material 100 is not particularly limited. For example, the first insulating material 100 may be a fiber-based insulating material, a foamed plastic-based insulating material, or the like. In one embodiment, the first insulating material 100 is a fiber-based insulating material.

[0012] The fibers contained in the fiber-based insulation material are inorganic fibers containing, for example, metal oxides and composite metal oxides. As an example, the inorganic fibers contain oxides containing at least one of silicon, aluminum, boron, alkali metals, alkaline earth metals, and other metals. Examples of fiber-based insulation materials include glass wool and rock wool. In one embodiment, the glass wool can be manufactured by a centrifugal method. For example, glass fiber raw material is put into a spinner having many small holes on the side and is thermally melted. Then, the spinner is rotated at high speed, and the glass is blown out in a fibrous state. The blown glass is air-cooled to manufacture glass wool in which glass fibers are entangled.

[0013] The average fiber diameter of the inorganic fibers can be 1 μm or more in one embodiment, 2 μm or more in another embodiment, and 3 μm or more in yet another embodiment, and can be 30 μm or less in one embodiment, 20 μm or less in another embodiment, 10 μm or less in yet another embodiment, and 5 μm or less in yet another embodiment.

[0014] The fiber-based insulation material may have a structure in which fibers are bound together by a binder resin. The binder resin may be a phenolic resin, an acrylic resin, an epoxy resin, a melamine resin, or a polyvinyl alcohol resin. A binder containing a naturally occurring material as a main component and substantially not releasing formaldehyde may be used.

[0015] The binder resin content relative to the total weight of the fiber-based insulation can be 1 weight% or more in one embodiment, 3 weight% or more in another embodiment, 5 weight% or more in a further embodiment, and 7 weight% or more in a further embodiment, and can be 20 weight% or less in one embodiment, 15 weight% or less in another embodiment, and 12 weight% or less in a further embodiment.

[0016] The density of the fibrous insulation material is 8 kg / m in one embodiment. 3 In another embodiment, 10 kg / m 3 or more, in a further embodiment, 16 kg / m 3 or more, and in one embodiment, 100 kg / m 3 In the following, in another embodiment, 80 kg / m 3 In the following, in further embodiments, 60 kg / m 3 In the following, in further embodiments, 32 kg / m 3 It can be as follows:

[0017] The first insulating material 100 is processed into a plate shape of a predetermined dimension in advance. The dimensions of the first insulating material 100 are not particularly limited, but can be selected according to the size of the filling location in the building. For example, in a wooden house with a 100-meter module, the distance between the pillar and the stud is about 395 mm. Therefore, the width W of the first insulating material 100 filled in the wall of the building, i.e., filled between the pillar and the stud, may be, for example, 390 mm or more and less than 400 mm. The width W of the first insulating material 100 may be 390 mm, 395 mm, or 400 mm.

[0018] 2 is a schematic diagram showing a method of applying the set of thermal insulation materials according to this embodiment to the wall of a building. The first thermal insulation material 100 as described above can be filled between a pillar 210 and a stud 220 as shown in FIG.

[0019] In this embodiment, such a first insulating material 100 can also be filled between the studs 220 and 230. As described above, in a wooden house with a 100-millimeter module, the distance between the studs is about 430 mm. Therefore, the size of the first insulating material 100 is insufficient to fill between the studs 220 and 230. On the other hand, in this embodiment, as shown in FIG. 2, a combination of the first insulating material 100 and the second insulating material 150 is filled between the studs 220 and 230.

[0020] In this way, the first insulating material 100 can be filled in various spaces having different dimensions. From this viewpoint, the first insulating material 100 may have a shape that fits the space having the smallest dimension among the multiple types of spaces. For example, the width of the first insulating material 100 may be approximately equal to the smallest width (e.g., the distance between a pillar and a stud) among the widths of the multiple types of spaces. That is, the width of the first insulating material 100 can be selected so that one first insulating material 100 can fill the first insulating material filling space (e.g., between a pillar and a stud). For example, the width of the first insulating material 100 may be approximately equal to the width of the first insulating material filling space. In this specification, two values ​​approximately equal means that the difference between the values ​​is within 10 mm. Two values ​​approximately equal may also mean that the difference between the values ​​is within 5 mm.

[0021] The material constituting the second insulating material 150 may be the same as the material constituting the first insulating material 100. Moreover, the second insulating material 150 is also pre-processed to have a shape with predetermined dimensions.

[0022] The shape of the second insulating material 150 is different from the shape of the first insulating material 100. In one embodiment, the first insulating material 100 has a first width W. The second insulating material 150 has a second width W, where the second width W is equal to or less than one-third of the first width W. The second width W may be equal to or less than one-quarter, one-fifth, one-sixth, one-seventh, one-eighth, one-ninth, or one-tenth of the first width W.

[0023] As described above, the second insulating material 150 is combined with the first insulating material 100 to fill a space. From this perspective, the first insulating material 100 and the second insulating material 150 may have a shape that fits the space into which the insulating materials are to be filled when they are arranged side by side. For example, the sum of the first width W of the first insulating material 100 and the second width W of the second insulating material 150 may approximately match the width of the space into which the insulating materials are to be filled (e.g., between studs).

[0024] On the other hand, the height H of the first insulating material 100 may be the same as the height H of the second insulating material 150. Also, the thickness D of the first insulating material 100 may be the same as the thickness D of the second insulating material 150. In this way, in order to facilitate filling into a desired space, the dimensions of the first insulating material 100 and the second insulating material 150 may differ only in the width W.

[0025] The specific dimensions of the second insulating material 150 are not particularly limited, but can be selected according to the size of the filling location in the building. For example, in order to fill the combination of the first insulating material 100 and the second insulating material 150 between the pillars and the partitions, the width W of the second insulating material 150 may be, for example, 30 mm or more and less than 40 mm. The width W of the second insulating material 150 may be 30 mm, 35 mm, or 40 mm.

[0026] The height H of the first insulating material 100 and the second insulating material 150 is not particularly limited and can be selected according to the size of the filling portion in the building. For example, the height H of the first insulating material 100 and the second insulating material 150 may be 500 mm or more and 4000 mm or less. The height H of the first insulating material 100 and the second insulating material 150 may be 2700 mm or more and 3000 mm or less. Specific examples of the height H of the first insulating material 100 and the second insulating material 150 include 1370 mm, 2350 mm, 2740 mm, and 2880 mm.

[0027] The thickness D of the first insulating material 100 and the second insulating material 150 is not particularly limited and can be selected according to the size of the filling portion in the building. For example, the thickness D of the first insulating material 100 and the second insulating material 150 may be 50 mm or more and 200 mm or less. Specific examples of the thickness D of the first insulating material 100 and the second insulating material 150 include 75 mm, 89 mm, 90 mm, 105 mm, and 155 mm.

[0028] So far, the dimensions of the first insulating material 100 and the second insulating material 150 have been described mainly in the case where the insulating material is filled into the walls of a wooden house constructed using a 100 cm module frame construction method. However, the dimensions of the first insulating material 100 and the second insulating material 150 can be selected according to the module (e.g., 100 cm module or meter module) and the construction method (e.g., frame construction method or framework construction method). In addition, the dimensions of the first insulating material 100 and the second insulating material 150 can be selected according to the filling space. Examples of filling spaces into which the first insulating material 100 and the second insulating material 150 are filled include spaces between pillars (walls), between foundations (floors), and between beams (ceilings).

[0029] As an example, a case where the insulation material is filled in the floor will be described. The distance between the base and the joists is often shorter than the distance between the joists. Therefore, the width W of the first insulation material 100 may be approximately equal to the distance between the base and the joists. Also, the sum of the first width W of the first insulation material 100 and the second width W of the second insulation material 150 may be approximately equal to the distance between the joists.

[0030] As shown in Fig. 1, a film 120 may be attached to the first insulating material 100. The first insulating material 100 can be filled in a desired space (e.g., a wall, etc.) of a building so that the film 120 faces the indoor side. Such a film 120 can prevent the flow of air and the movement of moisture between the indoor side and the first insulating material 100.

[0031] In one embodiment, as shown in FIG. 1, the film 120 is attached to the main surface (one end surface in the thickness D direction) of the first insulating material 100. The film 120 has an extension 121 that extends beyond a first end in the width direction of the first insulating material 100, and an extension 122 that extends beyond a second end in the width direction of the first insulating material 100. The film 120 can be fixed to a structure such as a pillar via such an extension. Here, the first end of the first insulating material 100 is an end opposite to the second end of the first insulating material 100. The extension 121 has a length E1 in the width direction of the first insulating material 100, and the extension 122 has a length E2 in the width direction of the first insulating material 100. 1, the film 120 may have an extension extending beyond a first end in the height direction of the first insulating material 100 and an extension extending beyond a second end in the height direction of the first insulating material 100. In this manner, the film 120 may be provided so as to cover the main surface of the first insulating material 100.

[0032] The material of the film 120 is not particularly limited, but may be, for example, a thermoplastic resin. Examples of the thermoplastic resin include polyolefin resins such as polyethylene and polypropylene. The thickness of the film 120 is not particularly limited, but may be, for example, 10 μm or more or 15 μm or more, and may be 60 μm or less or 50 μm or less.

[0033] Here, the widthwise length E2 of the extension 122 may be longer than the widthwise length E1 of the extension 121. The widthwise length E2 of the extension 122 may be longer than the width W of the second insulating material 150. Furthermore, the widthwise length E2 of the extension 122 may be equal to or greater than the sum of the widthwise length E1 of the extension 121 and the width W of the second insulating material 150, or may be approximately equal to the sum of the widthwise length E1 of the extension 121 and the width W of the second insulating material 150. With this configuration, the second insulating material 150 arranged to be aligned with the first insulating material 100 can be covered by the film 120 attached to the first insulating material 100, more specifically, by the extension 122. For this reason, the second insulating material 150 does not need to have a film attached. Furthermore, with this configuration, it becomes easy to fill the insulating material filling space with a combination of the first insulating material 100 and the second insulating material 150 and further cover it with a film. However, a film similar to that of the first insulating material 100 may be attached to the second insulating material 150 .

[0034] Each of the first insulation 100 and the second insulation 150 may have a passageway extending in the longitudinal direction. Providing a passageway is advantageous in that wiring or piping of the building may pass through the interior of such a passageway. Such a passageway may be, for example, a groove provided in the surface of the first insulation 100 and the second insulation 150.

[0035] FIG. 3 is a schematic diagram of the first insulating material 100 and the second insulating material 150 in which such a groove portion 300 is provided. The positions of the groove portion 300 in the first insulating material 100 and the second insulating material 150 are shown. In the example of FIG. 3, the groove portion 300 is provided on the main surface (one end surface in the thickness D direction) of the first insulating material 100 and the second insulating material 150. When the film 120 is attached to the first insulating material 100, such a groove portion 300 may be provided on the surface of the first insulating material 100 to which the film 120 is attached. However, the groove portion 300 may be provided on another surface of the first insulating material 100 and the second insulating material 150.

[0036] The shape of the groove portion 300 is not particularly limited. For example, the groove portion may have a cylindrical shape, a V-shape, or a tapered shape. The position of the groove portion 300 is also not particularly limited. As shown in FIG. 3, the groove portion 300 may extend in the width direction of the first insulating material 100 and the second insulating material 150. The groove portion 300 may also extend in the height direction of the first insulating material 100 and the second insulating material 150. Furthermore, the groove portion 300 may be provided in a lattice shape.

[0037] In one embodiment, the passages are provided so that the passages of the first insulating material 100 and the passages of the second insulating material 150 are continuous when the first insulating material 100 and the second insulating material 150 are arranged in the width direction. The height position (e.g., distance from the lower end) of the passages of the first insulating material 100 at the first end in the width direction of the first insulating material 100 and the height position (e.g., distance from the lower end) of the passages of the second insulating material 150 at the first end in the width direction of the second insulating material 150 are approximately the same. According to this configuration, when the first insulating material 100 and the second insulating material 150 are filled so that the first end of the first insulating material 100 and the first end of the second insulating material 150 are in contact with each other, wiring, piping, etc. can pass through the first insulating material 100 and the second insulating material 150 without coming out of the passages. For example, in the example of FIG. 3, grooves 300 are provided so that grooves 300 in the first insulating material 100 and grooves 300 in the second insulating material 150 are continuous with each other when filled.

[0038] Furthermore, the height position of the passage of the first insulating material 100 at a second end opposite to the first end in the width direction of the first insulating material 100 may be approximately the same as the height position of the passage of the second insulating material 150 at a second end opposite to the first end in the width direction of the second insulating material 150. With this configuration, wiring, piping, etc. can pass through the first insulating material 100 and the second insulating material 150 without coming out of the passage, regardless of the arrangement of the first insulating material 100 and the second insulating material 150.

[0039] By using a set of the first insulation material 100 and the second insulation material 150 as described above, insulation can be applied to a building as follows. First, the first insulation material 100 can be filled alone into the first insulation material filling space of the building. The first insulation material filling space is, for example, between a pillar and a partition wall. Next, the first insulation material 100 and the second insulation material 150 can be filled side by side in the width direction into the second insulation material filling space of the building. The second insulation material filling space is, for example, between partition walls. Note that the filling of the first insulation material 100 into the first insulation material filling space and the filling of the combination of the first insulation material 100 and the second insulation material 150 into the second insulation material filling space may be performed in the opposite order. In this way, a building filled with insulation can be manufactured.

[0040] Up to this point, the description has been mainly given of the case where the second insulation filling space of the building is filled with a combination of one first insulation material 100 and one second insulation material 150. However, the filling space may be filled with a combination of one first insulation material 100 and two or more second insulation materials 150. Also, when there are many different sizes of the filling space, a set of insulation materials having three or more different sizes may be used.

[0041] According to the configuration of the above embodiment, a combination of a first insulating material 100 and a second insulating material 150 that is significantly smaller than the first insulating material 100 is used. This makes it easier to store the insulating material compared to using insulating materials having dimensions that fit the first insulating material filling space (e.g., between a pillar and a stud) and the second insulating material filling space (e.g., between studs). Furthermore, according to the configuration of the above embodiment, there is less need to cut the insulating material, which simplifies the construction work.

[0042] The invention is not limited to the above-described embodiment, and various modifications and variations are possible within the scope of the gist of the invention. [Explanation of symbols]
