Description

  The present invention relates to an architectural heat insulator for forming a heat insulating wall in a general house or the like.

  2. Description of the Related Art In buildings such as general houses, heat insulators are increasingly used in order to reduce indoor temperature fluctuations to make the living environment comfortable and to save on cooling and heating costs.

  Conventionally, as a heat insulator, a material using a fiber-based heat insulating material such as glass wool has been used.

  However, glass wool and the like have drawbacks such as low airtightness, large energy loss, and easy formation of dew inside the frame. Recently, heat insulators using plate-like foamed resin have been widely used. ing.

  FIG. 8 shows a conventional example of a heat insulator using a foamed resin.

  The heat insulator 50 is made of a wooden square frame 52, a surface member 51 attached to one surface of the frame 52, and a foamed resin housed in a section defined by the surface member 51 and the frame 52. The heat insulating material 53 is formed.

  The face material 51 is formed of plywood or the like, and has a size capable of covering the frame-shaped portion 3 of the frame 2 of the building from the outside (or the inside). Here, the frame-shaped portion 3 means a frame formed by several shaft members (a base, a column 5, a horizontal member (a beam, a girder, etc., not shown)) constituting the shaft set 2. The vertical and horizontal dimensions of the frame 52 are determined so that the frame 52 can be fitted into the frame 3 of the shaft assembly 2 without any gap. Further, the heat insulating material 53 is foamed in the framework 52 and is firmly adhered to the inner surfaces of the face material 51 and the framework 52.

  In the heat insulator 50, the frame 52 is fitted into the frame 3 of the frame 2 of the building, and the peripheral portion 51 s of the face material 51 is nailed to the outdoor (or indoor) surface of the frame 3. Be beaten.

  By the way, the above-mentioned heat insulator 50 is heavy because it has the wooden frame 52 and the like. Therefore, it is difficult for the operator to handle the work, and the work efficiency is likely to be deteriorated. Further, if the frame 52 of the heat insulator 50 is too large, it cannot be fitted into the frame 3 of the frame 2, and if it is too small, a gap G is generated between the frame 3 and the heat insulating performance. . Therefore, it is necessary to manufacture the frame 52 of the heat insulator 50 with high accuracy, which increases the manufacturing cost.

Therefore, a heat insulator in which a heat insulating material is bonded to a face plate without using a frame has been proposed (see Patent Documents 1, 2, 3, and 4).

  By the way, in each of the above-mentioned heat insulators, at the time of disposal, a combustible material (a wooden surface material (51), a frame (52), etc.) and an incombustible material (a foamed resin heat insulator (53)) are separated. Is difficult. Particularly, in order to separate the heat insulating material (53) from the face material (51) and the framework (52), the heat insulating material (53) is firmly adhered to the face material (51) and the like. As described above, the operator has to tear off each piece by hand, which is very troublesome, and complete separation is practically impossible.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an architectural heat insulator in which sorting and disposal can be easily performed while improving workability, reducing costs, and preventing a decrease in heat insulation performance.

  In order to achieve the above object, an invention according to claim 1 is a sheet material made of paper, which can be bent and deformed by human power and can be closed by covering a frame-shaped portion with one surface in contact with the surface material. And a heat-insulating material made of a foamed resin that is bonded to the other surface of the sheet-like member and has a vertical and horizontal dimension that is larger by a predetermined length than the inside vertical and horizontal dimensions of the frame-shaped part. When the sheet material is assembled to the frame portion together with the surface material, the seal layer formed on the peripheral portion of the sheet member comes into contact with the outer surface of each shaft member of the frame portion, and each end of the heat insulating material is elastic. It is configured to be capable of peeling off the heat insulating material while deforming and deforming the sheet-shaped member when the sheet-shaped member is deformed and brought into close contact with the inner end of each shaft member, and the sheet-shaped member is removed from the frame-shaped portion. is there.

  According to the first aspect of the present invention, sorting and disposal can be easily performed while improving the workability, reducing the cost, and preventing the insulation performance from lowering.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 3A and 3B, a heat insulator 10 for a building according to the present invention is bonded to a sheet-like member 11 that can be flexibly deformed by human power and is attached to the sheet-like member 11. A heat insulating material 21 made of a foamed resin, and the heat insulating material 21 is elastically deformed and brought into close contact with the inner end of the frame-shaped portion 3 of the frame 2, and deforms the sheet-shaped member 11 by bending. The heat insulating material 21 can be peeled off.

  Specifically, as shown in FIGS. 1 and 2, the sheet-like member 11 is formed so as to be able to bend and deform by human power and to close and close the frame-like portion 3 in a state where the one surface 11 a is in contact with the surface material 17. Have been. The sheet-like member 11 may have any configuration as long as it can be flexibly deformed by human power. In this embodiment, the sheet-like member 11 is made of paper so as to be easily available and to reduce costs. In addition, it may be formed of a thin plastic plate or the like having flexibility.

  As shown in FIGS. 3 and 4, the heat insulating material 21 made of a foamed resin is adhered to the other surface 11b of the sheet-like member 11 so that the vertical dimension (L3) and the horizontal dimension (L4) are inside the frame-shaped section 3. It is formed larger by a predetermined length than the vertical dimension (L1) and the inner horizontal dimension (L2). The foamed resin material can be appropriately selected from foamed styrene resin, foamed polypropylene, foamed polyurethane resin, foamed polyisocyanurate resin, foamed phenolic resin, and the like.

  In addition, the sheet-like member 11 with the heat insulating material 21 is fixed to the face member 17 using a locking member 41 as shown in FIG. The locking member 41 extends in a direction orthogonal to the paper surface in FIG. 1 and is screwed to the face material 17 so as to sandwich the sheet-like member 11 with the heat insulating material 21.

  Further, in this embodiment, the outer peripheral portion 12 of the above-mentioned sheet-like member 11 is provided outside the shaft members (for example, the base 4, the pillar 5, and the horizontal member 6) that form the frame-like portion 3 of the frame 2. A seal layer 15 is formed which is in elastic contact with the side surfaces (4a, 5a, 6a) and is in close contact therewith.

  More specifically, the sheet-like member 11 with the heat insulating material 21 is formed as follows. On the other surface 11b of the sheet-like member 11, the foamed resin is foamed at a predetermined magnification to form a heat insulating material forming portion 21A having substantially the same size as the other surface 11b and a predetermined thickness D1. Next, as shown in FIGS. 5 and 6, an unnecessary portion 22 </ b> A is cut off from each end of the heat insulating material forming portion 21 </ b> A using the cutter 9. At this time, the predetermined thickness D2 portion is left without completely removing the portion 22A.

  As a result, the portion cut by the cutter 9 becomes the peripheral portion 12, and the sealing layer 15 made of the same material as the heat insulating material 21 and having a thickness D <b> 2 is formed on the peripheral portion 12. Note that the heat insulating material forming portion 21A may be manufactured at a place other than on the sheet-shaped member 11, and may be bonded to the other surface 11b of the sheet-shaped member 11 using an adhesive or the like after the formation.

  Then, as shown in FIGS. 2 and 4, when the sheet-like member 11 is assembled to the frame-like portion 3 together with the face material 17, as shown in FIGS. The layer 15) abuts (closely contacts) the outer surfaces (4a, 5a, 6a) of the shaft members (4, 5, 6) forming the frame-shaped portion 3 (in other words, the peripheral portion 12 is a face material). 17 and each shaft member (4 or the like)), and each end 22 of the heat insulating material 21 is elastically deformed and the inner end (4b, 5b, 6b) of each shaft member (4, 5, 6). When the sheet-like member 11 is detached from the frame-like portion 3 and is in close contact with the sheet-like member 11, the heat-insulating material 21 can be peeled off while bending and deforming the sheet-like member 11 as shown in FIG. .

  In the case of the heat insulator 10 having the above-described configuration, since the heat insulating material 21 is provided on the other surface 11b of the sheet member 11 without using a frame, when the sheet member 11 is joined to the face member 17 for construction. However, the weight can be significantly reduced as compared with the conventional example (FIG. 8). Therefore, it is easy for the operator to handle and the workability can be improved. Further, unlike the conventional example, no frame is required, so that the cost can be reduced.

  Further, since each end 22 of the heat insulating material 21 is elastically deformed and is in close contact with the inner end (4b, 5b, 6b) of each shaft member (4, 5, 6), each shaft member (4, 5 Even if the inside and outside dimensions of the frame-shaped portion 3 are slightly increased due to, for example, thinning of the tree, the heat insulating material 21 can absorb the dimensional change. Therefore, the close contact state between each end 22 of the heat insulating material 21 and the inner end (4b, 5b, 6b) of each shaft member (4, 5, 6) is maintained, so that a decrease in heat insulating performance can be prevented.

  When the heat insulator 21 removed from the frame member 3 by removing the face member 17 from the frame member 2 is disposed of, for example, the worker holds the end of the sheet member 11 with one hand and Hold the end of the heat insulating material 21 with one hand and move both hands away. As a result, as shown in FIG. 7, the sheet-like member 11 bends and deforms, and the heat insulating material 21 peels off without breaking. Therefore, separation and disposal can be easily performed.

  Further, since the sheet-like member 11 is made of paper, material cost is low and processing is easy. Therefore, cost can be further reduced. Further, the sheet-like member 11 can be largely bent and deformed without applying much force to separate the heat insulating material. Therefore, the separation and disposal can be more easily performed.

  Further, since the seal layer 15 is formed on the peripheral edge portion 12 of the sheet-like member 11 so as to be in elastic contact with the outer side surfaces 4a, 5a, and 6a) of the shaft members (4, 5, 6). The peripheral portion 12 of the member 11 and the outer surfaces (4a, 5a, 6a) of the shaft members (4, 5, 6) come into close contact with each other. Therefore, a decrease in the heat insulation performance can be more reliably prevented.
