  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,

An outer wall portion that is bent at the end in the longitudinal direction and extends so as to approach the wall surface;
The metal body edge body is formed by bending a metal second plate material,
The metal trunk rim body is integrated with the contact portion that can contact the wall surface and the contact portion, and is bent from the contact portion in the width direction orthogonal to the longitudinal direction to be separated from the wall surface. A side wall portion extending in the above manner, and a fixing portion that is integrated with the side wall portion, is bent from the side wall portion so as to be parallel to the contact portion, extends in the longitudinal direction, and the exterior material is fixed. And
The height in the said fixing | fixed part in the said metal trunk edge main body is more than the height from the said wall surface in the said attachment to the said support part, It is characterized by the above-mentioned.

  In the base material for exterior material construction according to the present invention, since the support portion of the attachment can be stored in the longitudinal direction in the fixing portion of the metal trunk body, when the attachment is fixed to the wall surface of the housing, the longitudinal length in the fixing portion of the metal trunk body The position where the anchor bolt is fixed can be relatively freely changed by avoiding the reinforcing bars in the direction. And the position of metal trunk edge main body itself can be made not to change. For this reason, the freedom degree of the position which fixes an attachment increases, and fixation of the base material for exterior material construction according to a construction condition is attained.

  Moreover, in this base material for exterior material construction, since there is no attachment between the abutting portion of the metal body edge main body and the wall surface, the carry-out distance between the wall surface and the exterior material does not become excessively large. . For this reason, the ventilation space ensured between a wall surface and an exterior material does not become thick.

  The first fixing portion stores the attachment substrate portion, the first and second inner wall portions, the first and second support portions, and the first and second outer wall portions in the longitudinal direction and the width direction, and the attachment fixing substrate in the second fixing portion. It is also possible to make the first fixing part wider than the second fixing part so that the first fixing part, the first and second inner wall parts, the first and second support parts, and the first and second outer wall parts are accommodated only in the longitudinal direction. .

The construction method of the exterior material of the present invention includes a first step of fixing the attachment to the wall surface of the housing with an anchor bolt,
