Description

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

  In a building such as a general house, a heat insulator is increasingly used in order to make the living environment comfortable by reducing the temperature fluctuation in the room and to save the heating and cooling costs.

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

  However, glass wool and the like have drawbacks such as low hermeticity, large energy loss, and easy formation of condensation in the housing. 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 insulating body 50 is made of a foamed resin housed in a section formed by a wooden square frame 52, a face material 51 attached to one side of the frame 52, and the face material 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 that covers the frame-like portion 3 of the building shaft 2 from the outdoor side (or indoor side). Here, the frame-like portion 3 means a frame formed by several shaft members (a base not shown, a pillar 5, a horizontal member (a beam, a girder, etc.) not shown) constituting the shaft assembly 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 2 without any gap. Further, the heat insulating material 53 is foamed or the like in the frame 52 and is firmly bonded to the face material 51 and the inner surface of the frame 52.

  The thermal insulator 50 has a frame 52 fitted into the frame-shaped portion 3 of the building frame 2 and a peripheral edge 51 s of the face material 51 nail on the outdoor side (or indoor side) surface of the frame-shaped portion 3. Be beaten.

  By the way, the above-described heat insulator 50 is heavy because it includes the wooden frame 52 and the like. Therefore, it is difficult for an operator to handle, and the work efficiency tends to deteriorate. In addition, if the frame 52 of the heat insulator 50 is too large, it cannot be fitted into the frame 3 of the shaft 2, and if it is too small, a gap G is generated between the frame 3 and the heat insulation performance is deteriorated. . Therefore, it is necessary to manufacture the frame 52 of the heat insulating body 50 with high accuracy, and the manufacturing cost increases.

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 said heat insulating body, when disposing, combustible [a wooden surface material (51), frame (52), etc.] and a nonflammable [a foamed resin heat insulating material (53)] are separated. Is difficult. In particular, in order to separate the heat insulating material (53) from the face material (51) and the frame (52), since the heat insulating material (53) is firmly bonded to the face material (51) and the like, it is shown in FIG. As described above, the operator has to scoop up one by one, which is very laborious and complete separation is practically impossible.

  An object of the present invention is to provide a building heat insulator that can be easily disposed of while being improved in workability, cost reduction, and prevention of deterioration in heat insulation performance.

In order to achieve the above object, the invention according to claim 1 is a sheet material member made of paper, which can be bent and deformed by human power, and can cover and close the frame-like portion with one surface in contact with the surface material. And a foamed resin heat insulating material that is bonded to the other surface of the sheet-like member and whose longitudinal and transverse dimensions are larger than the inner longitudinal and transverse dimensions of the frame-like portion by a predetermined length. Is assembled to the frame-shaped portion together with the face material, the seal layer formed on the peripheral portion of the sheet-shaped member abuts on the outer surface of each shaft member of the frame-shaped portion and each end of the heat insulating material is elastic. When the sheet-shaped member is deformed and closely adhered to the inner end portion of the shaft member and is removed from the frame-shaped portion, the heat-insulating material can be peeled while the sheet-shaped member is bent and deformed, and the seal The layer is formed continuously with the heat insulating material .

  According to the first aspect of the present invention, separation and disposal can be easily performed while improving workability, reducing costs, and preventing deterioration of heat insulation performance.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIGS. 1 to 3 (A) and (B), a thermal insulator 10 for a building according to the present invention is bonded to a sheet-like member 11 that can be bent and deformed by human power, and the sheet-like member 11. A heat-insulating material 21 made of foamed resin, the heat-insulating material 21 is elastically deformed and is in close contact with the inner end of the frame-like portion 3 of the shaft assembly 2, and the sheet-like member 11 is bent and deformed. 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 be bent and deformed by human power and to cover and close the frame-like portion 3 with one surface 11 a in contact with the face material 17. Has been. The sheet-like member 11 may be of any configuration as long as it can be bent and deformed by human power. In this embodiment, the sheet-like member 11 is made of paper so that it can be easily obtained and cost can be reduced. In addition, you may form by the plastic thin plate etc. which have flexibility.

  Further, as shown in FIGS. 3 and 4, the heat insulating material 21 made of foamed resin is bonded to the other surface 11 b of the sheet-like member 11, and the vertical dimension (L 3) and the horizontal dimension (L 4) are inside the frame-like part 3. It is formed larger than the vertical dimension (L1) and the inner horizontal dimension (L2) by a predetermined length. The foamed resin material can be appropriately selected from foamed styrene resin, foamed polypropylene, foamed polyurethane resin, foamed polyisocyanurate resin, foamed phenol resin, and the like.

  In addition, the sheet-like member 11 with the heat insulating material 21 is fixed to the face material 17 using a locking member 41 as shown in FIG. The locking member 41 extends in a direction perpendicular 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 peripheral edge portion 12 of the sheet-like member 11 described above is outside of each shaft member (for example, the base 4, the pillar 5, the horizontal member 6) that forms the frame-like portion 3 of the shaft assembly 2. A seal layer 15 is formed which is in elastic contact with and in close contact with the side surfaces (4a, 5a, 6a).

  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 the same size as the other surface 11b and having a predetermined thickness D1. Next, as shown in FIGS. 5 and 6, an extra portion 22 </ b> A is cut out 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 seal 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.

  2 and 4, when the sheet-like member 11 is assembled to the frame-like portion 3 together with the face member 17, the peripheral portion 12 (seal of the sheet-like member 11 is sealed. The layer 15) abuts (adheres) to the outer surface (4a, 5a, 6a) of each shaft member (4, 5, 6) forming the frame-like part 3 (in other words, the peripheral edge 12 is a face material). 17 and each shaft member (4, etc.)), and each end portion 22 of the heat insulating material 21 is elastically deformed to cause inner end portions (4b, 5b, 6b) of each shaft member (4, 5, 6). When the sheet-like member 11 is detached from the frame-like portion 3, as shown in FIG. 7, the heat-insulating material 21 can be peeled off while the sheet-like member 11 is bent and deformed. .

  In the case of the heat insulator 10 having the above configuration, since the heat insulating material 21 is provided on the other surface 11b of the sheet-like member 11 without using a frame, the sheet-like member 11 is bonded to the face material 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. In addition, unlike the conventional example, a framework is not necessary, so that cost can be reduced.

  In addition, 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). Even if the inner vertical and horizontal dimensions of the frame-shaped portion 3 are slightly increased due to thinning of the trees 5 and 6), the heat insulating material 21 can absorb the dimensional variation. Therefore, since 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, it is possible to prevent a decrease in heat insulating performance.

  Further, when disposing of the heat insulator 21 from which the face material 17 is removed from the frame assembly 2 and removed from the frame-shaped portion 3, for example, the operator holds the end portion of the sheet-like member 11 with one hand, Hold the end of the heat insulating material 21 with one hand and move both hands away. Thereby, as shown in FIG. 7, the sheet-like member 11 is bent and deformed, and the heat insulating material 21 is peeled off without being cut off. Therefore, separation and disposal can be performed easily.

  Moreover, since the sheet-like member 11 is made of paper, the material cost is low and it is easy to process. Therefore, the cost can be further reduced. Further, the heat insulating material can be separated by largely bending and deforming the sheet-like member 11 without applying too much force. Therefore, sorting and disposal can be performed more easily.

  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, 6a) of the respective shaft members (4, 5, 6). The peripheral edge 12 of the member 11 and the outer side surfaces (4a, 5a, 6a) of the shaft members (4, 5, 6) are brought into close contact with each other. Therefore, it is possible to more reliably prevent a decrease in heat insulation performance.

  The present invention is used when a general house is constructed.
