Description

  The present invention relates to a wall material fastener used when constructing a heat insulating wall composed of a heat insulating material and an exterior material.

  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).

  FIG. 9A shows an example of the wall material fastener A described in Patent Document 1. 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. 9 (b), the substrate 10 is fixed to a wall base 2 such as a pillar or girder by driving a fastening tool 7 such as a nail. 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 fixed to the wall base 2 such as a nail. The wearing tool 7 is driven and fixed. 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.

However, in the above-described conventional example, the heat insulating material 3 is moved forward (wall base) until the upper part of the heat insulating material 3 placed on the wall material fastener A is fixed to the wall base 2 with another wall material fastener A. It is difficult to perform the construction because the worker must support it by hand or temporarily fix the heat insulating material 3 to the wall base 2 with an adhesive or an adhesive tape so that it does not fall down (in the direction away from 2). There was a problem.

Therefore, when the heat insulating material 3 is supported by the wall material fastener A, the heat insulating material 3 is naturally inclined toward the wall base 2 and is put on the surface of the wall base 2. Thereby, the new heat insulating material 3 is attached to the upper side of the heat insulating material 3 and the heat insulating material 3 does not fall forward until the upper portion of the heat insulating material 3 is fixed to the wall base 2 with the wall material fixing device A. Thus, it is not necessary for the operator to support it by hand or to temporarily fix the heat insulating material 3 to the wall base 2 with an adhesive or an adhesive tape.

  Next, the airtight tape 66 is stuck so as to close a gap formed between the heat insulating materials 3 and 3 adjacent to each other with the heat insulating material support piece 21 interposed therebetween. This airtight tape 66 is a tape material formed by providing an adhesive layer on a non-breathable base material, and by adhering the airtight tape 66 over the heat insulating materials 3 and 3 adjacent to each other, a gap is formed. It is blocked to prevent a decrease in heat insulation.

  Next, another exterior material 4 is supported on the wall material fastener A. That is, by inserting the groove 61 at the lower end of the new exterior material 4 into the upward holding piece 45 of the exterior material holding part 22 of the wall material fastener A attached to the wall base 2, the exterior material 4 is attached to the wall material fastener. A is held and supported. Here, the lower exterior material 4 and the exterior material holding part 22 of the wall material fastener A are covered with the lower end of the upper exterior material 4.
