Description

  The present invention relates to a support structure for supporting external accessories such as a fence or a balcony provided so as to protrude from a building outer wall surface.

  In general, an external accessory such as a fence provided so as to protrude from the outer wall surface of a building is supported by arms that extend from the building frame. This type of arm often projects in a direction perpendicular to the outer wall surface of the building. However, as shown in FIG. 7, as the external accessory 100, there is one having a corner portion 101 along the building corner 200, and such a corner portion 101 is not directly supported by the arm 300. For this reason, the rigidity tends to be lower than that of other parts, and when a load is applied due to wind, rain, snow, or the like, the corner portion tip 101a is likely to bend or deform.

  In view of this, a support structure has been proposed in which a corner portion of an external accessory is directly supported by an oblique arm projecting obliquely from a projecting corner (see, for example, Patent Document 1). According to this support structure, the rigidity of the corner portion of the external accessory can be maintained satisfactorily, and bending and deformation at the tip of the corner portion can be suppressed.
