  Note that the corners on the interior side of the gypsum board 3a of the face material 3 are chamfered in order to prevent twisting and collision when the panels A1 and A2 are built. Therefore, a gap E is formed between the panels A1 and A2 in the corner corner portion e on the room i side of the first and second outer wall panels A1 and A2 that intersect at right angles.

  The corner member B includes a frame member 7a having a substantially U-shaped cross section attached to the frame 2 of the first outer wall panel A1, and a frame member 7b attached to the frame 2 of the second outer wall panel A2. And a corner exterior material 9 supported by the frame members 7a and 7b via the wood substrate 5 and the mounting bracket 8 respectively.

  A heat insulating material 6 such as rock wool is also disposed between the frame members 7a and 7b. Thereby, in the corner part C1, the heat insulating material 6 is continuously distribute | arranged over 1st outer wall panel A1, the corner member B, and 2nd outer wall panel A2. The other corner portions C2 to C6 have substantially the same configuration.

  Further, a corner material 10 is disposed in the corner corner portion e on the indoor side. The corner material 10 includes a flat plate portion 10a attached to the indoor side surface material 3 of the first outer wall panel A1 and a flat plate portion 10b attached to the indoor side surface material 3 of the second outer wall panel A2. Are formed of an angle-shaped member that bends at approximately 90 degrees.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of a corner material 11 of the present embodiment, and FIG. 2 is a perspective view thereof. 3 is a partial cross-sectional view of the corner material 11 of the present embodiment mounted on the corner portion C1 of the house 1 shown in FIG. 6, and FIG. Note that the first outer wall panel A1, the second outer wall panel A2, and the corner member B have the same configuration as that of the prior art, and thus description thereof is omitted here.

  In the figure, the corner material 11 of the present embodiment is disposed in a gap E between the panels formed in the corner corner portion e on the interior i side of the first and second outer wall panels A1 and A2 that intersect at right angles. It is formed as a scale and extends continuously in the longitudinal direction in the cross section of FIG.

Specifically, the corner material 11 includes a base portion 12, a flange portion 13, and a heat insulating material 14.

  The base portion 12 includes a first flat plate portion 12a attached to the indoor-side face material 3 of the first outer wall panel A1 (in this example, the plasterboard 3a disposed closest to the indoor side), and a second outer wall. The interior angle α formed by the second flat plate portion 12b attached to the indoor surface member 3 of the panel A2 (in this example, the plasterboard 3a disposed most indoors) is bent at an angle of approximately 90 degrees. It is formed.

  Further, it is preferable that, for example, an adhesive portion 15 whose outer surface is covered with a release paper is fixed in advance to the outdoor side surface of each flat plate portion 12a, 12b.

  Further, in the present embodiment, a plurality of holes 16 are formed in each of the flat plate portions 12a and 12b as shown in FIG. The hole 16 effectively functions as an adhesive reservoir for accumulating an adhesive when a cloth or the like is attached so as to cover the base 12 with the adhesive.

  As shown in FIG. 1, the flange portion 13 is formed with a thickness t that allows the outer angle β of the base portion 12 to bisect and can be inserted into the gap E from the indoor side. That is, the thickness t of the collar portion is formed smaller than the dimension T of the gap E. In addition, although the collar part 13 is formed with fixed thickness t in this embodiment, it is not limited to such an aspect.

  The flange portion 13 and the base portion 12 are, for example, a resin, preferably a molded article such as an ABS resin that is excellent in the balance of mechanical properties such as rigidity, workability, impact resistance, and bending fatigue resistance. In particular, the base portion 12 and the collar portion 13 are preferably formed integrally in advance. This helps to produce the corner material 11 at low cost.

  The heat insulating material 14 is fixed to both sides of the flange 13 and, as shown in FIG. 1, is fixed to the flange 13 so as to cover the free end 13e without exposing the free end 13e of the flange 13. Has been.

  As the heat insulating material 14, for example, a heat insulating material having a heat insulating performance of less than 0.050 (W / mk) is desirable. Moreover, the heat insulating material 14 is preferably a foamed resin material capable of relatively large compression deformation, such as polystyrene foam, urethane foam, polyethylene foam, or the like.

  Further, as shown in FIG. 1, the heat insulating material 14 of the present embodiment has a width FW (this width is the cross section of FIG. 1) from the base 12 side toward the free end 13 e side of the flange 13. (Measured in a direction perpendicular to the longitudinal direction of the flange 13) is formed in a substantially fan shape. Further, the maximum dimension of the width FW of the heat insulating material 14 is larger than the dimension K of the gap E.

  As shown in FIG. 3 and FIG. 4 which is a partially enlarged view of the corner material 11 configured as described above, the first and second outer wall panels A1 previously built at a right angle through the gap E are used. , A2 is inserted into the gap E from the room i side. The corner material 11 is inserted into the gap E from the heat insulating material 14 side. At this time, since the heat insulating material 14 has a width larger than the dimension (width) T of the gap E, it is inserted into the gap E while being elastically compressed and deformed.

  Further, the corner material 11 is inserted in such a manner that the first flat plate portion 12a is on the indoor side surface material 3 of the first outer wall panel A1, and the second flat plate portion 12b is on the indoor side surface of the second outer wall panel A2. This is performed up to the position where the adhesive 3 is attached to the material 3. And in the state of this insertion completion, the heat insulating material 14 of the corner material 11 can be in close contact with the end surface of the indoor side face material 3 of each outer wall panel A1, A2. Specifically, the heat insulating material 14 closely contacts not only the chamfered portion 3e and the non-chamfered portion 3n of the end face of the gypsum board 3a but also the end face of the polystyrene board 3b.

  The corner material 11 as described above closes the gap E between the panels A1 and A2, and forms a sharp edge at the corner corner portion e. To help.

  Further, the gap E is blocked by the heat insulating material 14 in the corner corner portion e on the indoor side. In particular, in this embodiment, the polystyrene boards 3b and 3b and the heat insulating material 14 can be continuously insulated without being interrupted at the corner. Therefore, it is possible to improve the heat insulation of the gap portion between the panels A1 and A2 and effectively prevent dew condensation from occurring at the corners of the corner corners e on the indoor side.

  Furthermore, in this embodiment, the free end 13e of the collar part 13 is covered with the heat insulating material 14 and is not exposed at the corner part. Therefore, it is possible to effectively prevent the ridge portion 13 from becoming a so-called thermal bridge and the cold heat from being transmitted to the corner corner portion e.

  Furthermore, in the present embodiment, the corner corner portion e can be more reliably insulated by the extremely simple operation of inserting the corner material 11 into the gap E between the panels from the room i side. Therefore, the productivity of industrialized houses can be greatly improved.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention can be deform | transformed and implemented in various aspects, without being limited to said embodiment.
