Description

  The present invention relates to an interior corner member and an exterior wall interior corner structure capable of easily and inexpensively constructing an exterior wall interior corner of a building.

  When the planar shape of the building is an L shape, a concave shape, or the like and is not rectangular, an entrance corner (hereinafter referred to as an “outer wall entrance corner”) is generated on the outer wall. When the outer wall corner is formed by using an outer wall plate such as a siding board, the outer wall corner is formed by bending a long steel plate into a substantially L shape as shown in FIG. In addition, a part of the backup member 71 formed by bending a long steel plate into a cross-sectional ridge shape having a convex portion 71a at one end is used so as to cover the butt portion of the outer wall plate material 72 forming the outer wall. Generally, the sealing material 73 is filled and stored between the intervals. In addition, as shown in FIG. 6, a resin backup material 74 may be used instead of the backup member 71. In these cases, since the sealing material 73 is expensive, the convex portion 71a and an inexpensive resin backup member 74 are used for the joint base for the purpose of saving this. However, in these accommodations, the work of attaching the backup member 71 and the backup material 74 is necessary, and the work is troublesome. Further, in the case shown in FIG. 5, two metal members are required, which is expensive.

Therefore, there are a member for a corner where a cushioning material is attached to a corner of a metal plate formed in a substantially L shape, and an outer wall corner structure using the corner member (see, for example, Patent Document 1). According to this corner member and the outer wall corner structure using the corner member, the work of attaching the backup member or the resin backup material is unnecessary, and labor can be saved.
