Description

  The present invention relates to a connection structure of a heat insulating material that can be suitably used for new construction and renovation of a wooden building, a steel building, a reinforced concrete (RC) building, and the like.

  Conventionally, a heat insulating wall made of a heat insulating material and an exterior material is formed on the outside (outdoor side) of a wall base, and is used as a renovation using the wall base as an existing wall. In forming such a heat insulating wall, a wall material fastener for attaching and holding a heat insulating material and an exterior material to a wall base is used (for example, refer to Patent Document 1).

  An example of the wall material fastener A described in Patent Document 1 is shown in FIG. In this wall material fastener A, a support plate 11 for supporting the heat insulating material 3 and the exterior material 4 is extended from the surface of the substrate 10 fixed to the surface of the wall base 2, and on the front and back surfaces of the support plate 11 A locking piece 12 for positioning the heat insulating material 3 applied to the surface of the substrate 10 is erected, and the exterior is separated from the positioning locking piece 12 by a necessary space width S on the tip side of the support plate 11. A pair of positioning locking pieces 13, 14 that are engaged with the ends of the material 4 are erected on the support plate 11.

  And when constructing | assembling a heat insulation wall using the said wall material fastener A, it carries out as follows. First, as shown in FIG. 16B, a fastener 7 such as a nail or a screw is driven into and fixed to the substrate 10 disposed on the surface of the wall base 2 such as a column or a girder. Then, a heat insulating material 3 made of foamed resin or the like is installed between the substrate 10 and the locking piece 12, and then an exterior material 4 such as a fiber reinforced cement board is installed on the locking pieces 13 and 14. The exterior material 4 is formed with joint steps that are fitted to each other at the upper and lower edges, the locking piece 13 is in contact with the back surface of the exterior material 4, and the locking piece 14 is a fitting groove formed in the exterior material 4. Is engaged. After installing and positioning the lower ends of the heat insulating material 3 and the exterior material 4 in this way, a wall material fastener A different from the above is applied to these upper end portions, and the substrate 10 is attached to the wall base 2 with nails, screws, or the like. Fix with the fasteners 7. Then, the heat insulating material 3 and the exterior material 4 different from the above are placed on the wall material fastener A disposed at the upper end portions of the heat insulating material 3 and the exterior material 4 in the same manner as described above. In this way, by sequentially attaching the wall material fastener A, the heat insulating material 3 and the exterior material 4 to the wall base 2, the heat insulating wall can be formed outside the wall base 2.

In said heat insulation wall, since the clearance gap 65 for the thickness of the support plate 11 is formed between the heat insulating materials 3 and 3 adjacent to the upper and lower sides, there exists a possibility that heat insulation may be impaired. Therefore, as shown in FIG. 17, the gap is made substantially full length by sticking an airtight tape 66 in the width direction (horizontal direction) of the heat insulating material 3 on the outer surface (outdoor side surface) of the heat insulating materials 3 and 3. However, when the airtight tape 66 is pasted, the upper end of the exterior material 4 is positioned at the same height as the gap 65. Therefore, there is a problem that it is difficult to perform the operation of attaching the airtight tape 66.
