  However, since the base material for exterior material construction in Patent Document 1 is directly fixed to the wall surface mainly by the anchor bolt, the position to be fixed to the wall surface is limited. For example, if there is a reinforcing bar that interferes with the anchor bolt in the wall surface to fix the exterior material construction base material, the exterior material construction base material cannot be fixed at that position. The base material for the exterior material construction must be fixed at a position shifted from the position. Such a defect is conspicuous in the case of a reform in which it is not always clear where the reinforcing bar or the like is present in the housing. In addition, even in the case of a newly built frame, this problem becomes prominent even when an exterior material is applied to a corner where a reinforcing bar or the like is likely to exist. That is, in these cases, the construction of the exterior material becomes difficult.

  On the other hand, the base material for exterior material construction as in Patent Documents 2 and 3 employs an attachment together with a metal body. For this reason, if these base materials for exterior material construction are adopted, if there is a reinforcing bar or the like at a position where the attachment is to be fixed, the attachment is fixed at another position, and the position of the metal trunk body itself is not changed. It is also possible to do so. In this case, the above-mentioned problem of Patent Document 1 can be solved.

  However, in the base material for exterior material construction as in Patent Documents 2 and 3, the attachment overlaps the contact portion of the metal trunk edge main body or protrudes from the contact portion. For this reason, when exterior materials are constructed using these exterior material construction base materials, the carry-out distance between the wall surface and the exterior material increases, and the ventilation space secured between the wall surface and the exterior material increases. End up. For this reason, the construction is difficult in a narrow area, or the size of a screw or the like for fixing the exterior material is limited. In this case, it cannot be said that the workability of the exterior material is still sufficient.

  The present invention has been made in view of the above-described conventional situation, and provides an exterior material construction base material capable of making the exterior material workability more excellent, and an exterior material construction method. It is a problem to be solved.

The base material for exterior material construction of the present invention is an attachment fixed to the wall surface of the housing,
