Description

  The present invention relates to an outer wall accessory attached to a joint between adjacent exterior materials or a corner, and a joint or corner between adjacent metal siding and ceramic siding using the outer wall accessory. This relates to the outer wall structure of the part.

  Conventionally, in the construction of ceramic siding or metal siding as an exterior material provided on the wall base material of a building such as a house, the outer wall prevents rainwater from entering the joints or corners between adjacent exterior materials. Services are provided and consideration is given to watertightness. For example, in the construction of ceramic siding, a hat-type joiner as shown in FIG. 5 of Patent Document 1 is known as an outer wall accessory. The hat-type joiner includes a base portion fixed to the wall base material and a convex portion that bulges from the base portion. This hat-type joiner is mounted with the base fixed to the wall base material, the end of the ceramic siding is overlapped with the base, and the end face of the ceramic siding faces each other and abuts against the convex part. Attached to. A sealing material on the front side of the convex portion is filled in the joint portion.

  However, there are cases where the sealing material is bonded to two opposite end surfaces of the ceramic siding on both sides and the front surface of the convex part of the hat-type joiner, so-called three-side bonding. When three-sided adhesion occurs, stress due to expansion and contraction of the exterior material concentrates on the sealing material, and the sealing material is likely to be cut off, which may cause rainwater intrusion and an uncomfortable appearance. Furthermore, in the construction of the sealing material, masking and primer treatment are necessary, and a long construction time is required.

  On the other hand, different sidings such as metal siding and ceramic siding may be applied separately (for example, FIG. 4 of Patent Document 2). In the construction of metal siding, it is usual to provide a parting edge as an outer wall accessory at the end of the metal siding. For this reason, when installing metal siding and ceramic siding separately, use the hat-type joiner as the ceramic siding accessory and the parting edge for metal siding at the joint area. To do.
