  By the way, when the base material and the heat insulating plate are sequentially attached to configure the outer heat insulation, there is an advantage that the bearing wall can be configured by using the structural plywood as the base material, but the base material and the heat insulating plate are attached separately separately, There are problems such as inking, positioning, screw preparation, and screw pitch adjustment. On the other hand, when a conventional composite insulation panel for external insulation is used, the size is adapted to the module of the building, and a small hole indicating the screwing position of the screw is also formed. Time and effort such as pitch adjustment is reduced. However, since the heat insulating plate is attached between the shaft assembly and the face material, the bearing wall cannot be configured only by attaching the composite heat insulating panel for outer heat insulation. Moreover, the point which requires the effort which prepares a screw separately is the same.

  The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a composite heat insulation panel for external heat insulation that can be configured with a load-bearing wall and a method for attaching the composite heat insulation panel. .

In the first aspect of the present invention, in the composite heat insulation panel for outer heat insulation in which a face material is joined to one side of a heat insulating plate made of a synthetic resin foam having a size adapted to a module of a building ,
Bis required to secure the framing of the building, along a position corresponding to the shaft assembly for mounting to the shaft set of the building, from the other surface side of the insulation board, without penetrating the surface material, after The present invention provides a composite heat insulation panel for heat insulation, wherein the end is inserted into the heat insulation plate to a depth where it enters the heat insulation plate, and a predetermined number of pieces are temporarily fixed at a predetermined pitch .

The first of the present invention are bis is screwed to the face plate or implanted Tei Rukoto,
The insulation plate and the face material are joined so as to be peelable by a tucker or an adhesive.
The periphery of the face material is inside from the periphery of the heat insulating plate,
The other side of the heat insulating plate is covered with a moisture permeable waterproof sheet that is attached so that the insertion part of the screw into the heat insulating plate can be exposed,
Is included as a preferred embodiment thereof.

  The second aspect of the present invention is the composite heat insulation panel for external heat insulation according to any one of the first aspect of the present invention, wherein the face material is directed toward the shaft assembly side of the building and directed to the outside of the shaft assembly, The present invention provides a method for mounting a composite heat insulation panel for external heat insulation, which is characterized by passing through a face material and screwing it into a shaft assembly.

  The second aspect of the present invention includes filling a foaming resin into a screw through hole left in the heat insulating plate after screwing the screw into the shaft assembly as a preferable mode.

  According to the composite heat insulation panel for external heat insulation of the present invention, since the screw is inserted into the heat insulating plate and temporarily fixed, the screw can be screwed into the shaft assembly without preparing a separate screw. Can be attached. If the screws are temporarily fixed at the necessary positions at the required pitch, the installation as designed can be easily performed and the inspection work can be facilitated. Since the rear end of the screw enters the heat insulating plate, it is possible to prevent the rear end of the screw from being caught by something and coming off. In addition, because it is sized according to the module of the building, the trouble of marking out and aligning is reduced, and the face material is attached with the frame assembly side, so the face material is composed of structural plywood Thus, the bearing wall can be configured by attaching the composite heat insulation panel for extraneous heat insulation.

  If the screw is screwed or driven into the face material to a depth that does not penetrate the face material, the temporary fixing force of the screw can be strengthened, and even if an impact or the like is applied during transportation, the screw can be reliably prevented from falling off. Further, since the tip of the screw is not exposed through the face material, it is possible to prevent injuries caused by touching the tip of the screw.

  When the heat insulating plate and the face material are bonded to each other by a tacker or an adhesive, the heat insulating plate and the face material can be easily separated and discarded at the time of disposal.

  If the peripheral edge of the face material is inside from the peripheral edge of the heat insulating plate, even if the side surfaces of the heat insulating plate of the external heat insulating composite heat insulating panel attached adjacent to each other are closely attached, there is a gap between the face materials It is possible to prevent deformation due to thermal expansion and pressing of the face material.

  If the other side of the heat insulating plate is covered with a moisture-permeable waterproof sheet that is attached so that the screw insertion part can be exposed, the screw insulation operation of the external heat insulating composite panel will not occur without hindering the screw screwing operation. Installation of the moisture permeable waterproof sheet can be completed simultaneously with the installation.

  Moreover, according to the attachment method of this invention, the above simple attachments are attained.

  And if a foamable synthetic resin is filled in the hole left in the heat insulating plate after screwing the screw into the shaft assembly, it is possible to prevent a decrease in heat insulating property due to the hole.

It is a perspective view by the side of the face material side of the composite heat insulation panel for outer heat insulation shown by FIG. It is explanatory drawing of the temporary fix | stop state of a screw. It is plane sectional drawing of the state which attached the composite heat insulation panel for external heat insulation which concerns on this invention to the frame of a building. It is plane sectional drawing which shows an example of the outer wall structure comprised using the composite heat insulation panel for outer heat insulation which concerns on this invention. It is a perspective view which shows the other example of the composite heat insulation panel for external heat insulation which concerns on this invention.

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

  As shown in FIG. 1 and FIG. 2, a composite heat insulation panel 1 for external heat insulation according to the present invention has a face material 3 attached to one side of a heat insulation plate 2 made of synthetic resin foam.

  As a synthetic resin foam which comprises the heat insulation board 2, a polystyrene resin foam, a polyethylene resin foam, a polypropylene resin foam, a polyurethane resin foam, a phenol resin foam etc. can be used, for example. . Among these, polystyrene foam is preferred because of its low water absorption and excellent heat insulation. Moreover, although a bead foam molded body or an extrusion foam molded body may be sufficient, since it is excellent in pressure resistance, an extrusion foam molded body is preferable.

  As the face material 3, a plywood is usually used. In particular, a structural plywood is preferably used because a bearing wall can be formed by mounting the composite heat insulation panel 1 for external heat insulation.

  The heat insulating plate 2 has a size that matches the module of the building to which the composite heat insulating panel 1 for external heat insulation is attached. The face material 3 is slightly smaller than the heat insulating plate 2, and the periphery of the face material 3 is the heat insulating plate 2. Inside from the periphery. By adjusting the size of the heat insulating plate 2 to the module of the building, it is possible to attach the composite heat insulating panel 1 for external heat insulation without adjusting the dimensions except for a special portion. Moreover, even if the side surface of the heat insulation board 2 of the composite heat insulation panel 1 for the outer heat insulation attached adjacently because the periphery of the face material 3 is located inward from the periphery of the heat insulation board 2, the face material A gap (usually 1 to 6 mm) can be secured between the three side surfaces, and lifting due to thermal expansion and pressing of the face material 3 can be prevented. For example, in the case of the conventional procedure of attaching a heat insulating plate after attaching a structural plywood as a base material, the attachment is performed so that a gap is formed between the base materials. By retreating inward from the peripheral edge of 2, it is possible to omit the labor of inking.

  Although the attachment of the face material 3 to the heat insulating plate 2 may be performed by adhesion with an adhesive, it is preferably performed so as to be peelable with a tacker or an adhesive (for example, double-sided tape). If the heat insulating plate 2 and the face material 3 can be peeled, the heat insulating plate 2 made of synthetic resin and the face material 3 made of wood can be easily separated and discarded at the time of disposal.

  Screws 4 are inserted from the other surface of the heat insulating plate 2 (the side opposite to the face material 3) until the rear end enters the heat insulating plate 2. The screw 4 inserted into the heat insulating plate 2 is temporarily fixed in a state where it cannot be easily pulled out by frictional resistance with the heat insulating plate 2 which is a synthetic resin foam. Further, since the rear end of the screw 4 enters the heat insulating plate 2, it is possible to prevent the screw 4 from dropping due to something caught on the rear end of the screw 4.

  This screw 4 is not only inserted into the heat insulating plate 2 until its rear end enters the heat insulating plate 2, but also screwed into the surface material 3 to a depth not penetrating the face material 3, as shown in FIG. It is preferable that it is driven in. By tightening the tip of the screw 4 into the face material 3, it can be firmly fixed, and the screw 4 is surely prevented from dropping even when an impact is applied during transportation of the composite heat insulation panel 1 for outer heat insulation. can do. Moreover, since the screw 4 does not penetrate the face material 3, the tip of the screw 4 is exposed from the face material 3, and it is possible to prevent injuries caused by touching this.

  As shown in FIG. 3 (a), a screw through hole 5 may be formed in the heat insulating plate 2 as an insertion trace of the screw 4 into the heat insulating plate 2, but as shown in FIG. 3 (b), A screw through hole 5 having a diameter slightly smaller than the maximum diameter of the screw 4 is formed in the heat insulating plate 2 in advance, and the screw 4 is inserted into the screw through hole 5 and temporarily fixed, or the front end is attached to the face material 3. It may be one that has been tightened by screwing or driving to enhance the temporary fixing force.

  The screw 4 is temporarily fixed at a position corresponding to the position of the building framework 6 (see FIG. 4). That is, when the outer heat insulating composite heat insulation panel 1 is attached to the shaft assembly 6, a predetermined number is temporarily fixed at a predetermined pitch along a position on the shaft assembly 6. By doing in this way, the composite heat insulation panel 1 for external heat insulation can be attached to the frame assembly 6 with the position, pitch, and number of screws 4 as designed, and in particular, a bearing wall is constructed using a structural plywood as the face material 3 When doing so, the construction according to the standard can be performed reliably. Further, by checking whether the temporarily fixed screw 4 is sufficiently screwed into the shaft assembly 6, it is possible to easily inspect the construction state.

  As shown in FIG. 4, the composite heat insulation panel 1 for heat insulation according to the present invention is directed to the outside of the shaft assembly 6 with the face material 3 facing the shaft assembly 6 side of the building, and the screw 4 temporarily fixed It is attached by passing through the face material 3 and screwing it into the shaft assembly 6. By screwing the screws 4 until the face material 3 is firmly fixed to the shaft assembly 6, the face material 3 and the shaft assembly 6 can be integrated. If a structural plywood is used as the face material 3, A bearing wall can be constructed. Further, since the screw 4 temporarily fixed is surrounded by the heat insulating plate 2 and is erected, there is an advantage that it is difficult to fall down when screwed into the shaft assembly 6 and the screwing operation is easily performed. In FIG. 4, 6a is a pillar, and 6b is a spacer.

  After the outer heat insulating composite heat insulating panel 1 is attached to the shaft assembly 6 as described above, normally, a moisture permeable waterproof sheet 7 is temporarily fixed on the heat insulating plate 2 as shown in FIG. The outer wall is formed by attaching the ventilation trunk edge 8 on the wet waterproof sheet 7 and attaching the outer wall material 9 on the ventilation trunk edge 8. The attachment of the ventilator rim 8 is usually performed by nailing the shaft assembly 6 from the ventilator rim 8 through the outer heat insulating composite heat insulation panel 1. Since the moisture-permeable waterproof sheet 7 is pressed by the ventilation trunk edge 8, it is sufficient that the temporary fixing does not shift during construction.

  As described above, the outer surface of the heat insulating plate 2 is covered with the moisture permeable waterproof sheet, and the air on the heat insulating plate 2 side becomes static air, so that the screw penetration left on the heat insulating plate 2 after the screw 4 is screwed into the shaft assembly 6. Even if the hole 5 is left as it is, it does not become a large insulation defect. However, if the foam through-hole 5 is filled with a foamable synthetic resin, it is possible to reliably prevent a decrease in heat insulation performance. As the foamable synthetic resin, for example, a foamable urethane resin can be used.

  As the composite heat insulation panel 1 for external heat insulation according to the present invention, as shown in FIG. 6, a moisture permeable waterproof sheet 7 is attached to the other surface of the heat insulating plate 2 (the side opposite to the face material 3). be able to. The moisture-permeable waterproof sheet 7 can be attached with a double-sided tape or an adhesive. The moisture permeable waterproof sheet 7 is stuck so as to expose the insertion portion of the screw 4 into the heat insulating plate 2 so as not to hinder the screwing operation of the screw 4 (see FIG. 6). In FIG. 6, the hatched portion is a sticking portion 10 made of double-sided tape or the like, and in the example of (a), only one side edge portion of one moisture-permeable waterproof sheet 7 covering the heat insulating plate 2 is the sticking portion 10. 2 is attached. In the example of (b), the heat insulating plate 2 is covered with two moisture permeable waterproof sheets 9 in which adjacent edges overlap each other vertically, and each moisture permeable waterproof sheet 7 is attached to only one side edge. The part 10 is attached to the heat insulating plate 2. In any case, the moisture permeable waterproof sheet 7 can be rolled up from the side where it is not adhered, and the screw 4 can be screwed in by exposing the portion where the screw 4 is inserted into the heat insulating plate 2 by rolling up. It has become. If such a moisture permeable waterproof sheet 7 is stuck, the temporary fixing of the moisture permeable waterproof sheet 7 is completed simultaneously with the attachment of the composite heat insulating panel 1 for outer heat insulation to the shaft assembly 6 (see FIG. 5). Can do.
