Description

  The present invention relates to a structure of a connecting portion of an exterior material that completes a joint between left and right exterior materials when an exterior material is arranged on a base of an outer wall.

  Conventionally, when constructing the exterior material 2 on the outer surface side of the outer wall body 1 of a building, for example, as shown in FIG. A barrel edge 4 is attached to the outer surface side of the outer wall main body 1 via a heat insulating board 3, and a plurality of exterior members 2 are attached to the outer surface side of the barrel edge 4 side by side and vertically. The exterior material 2 is a so-called metal siding material in which a synthetic resin foam is lined on the back surface of a metal plate having a concavo-convex pattern on the surface. The exterior material 2 is provided with a male fruit 5 at the upper end and a female fruit at the lower end, and the exterior material 2 adjacent in the vertical direction is connected by fitting the male fruit 5 and the female fruit.

  The exterior materials 2 adjacent to the left and right are connected via a joiner A composed of a base material 6 and a cover material 7. A base material 6 is arranged in the vertical direction along the trunk edge 4 on the back side of the exterior material 2 between the left and right exterior materials 2, and the base material 6 is attached to the trunk edge 4. The cover material 7 is arranged in the vertical direction on the front side from the exterior material 2, and the fitting portion 8 provided on the back portion of the cover material 7 is fitted to the receiving portion 9 provided on the base material 6 so that the cover material 7 is The outer surface side of the edge of the exterior material 2 is pressed on both sides of the cover material 7.

  The connection using the joiner A composed of the base material 6 and the cover material 7 as described above has an advantage that the mounting position of the base material 6 and the cover material 7 is not restricted because the cross-sectional shape in the longitudinal direction does not change. However, since there is no portion that is caught in the longitudinal direction, the holding of the cover material 7 against the longitudinal force depends on the frictional force of the cover material 7 and the base material 6 or the cover material 7 and the exterior material 2. For this reason, there is a possibility that the cover material 7 that is applied with a force due to thermal expansion and contraction or the like easily moves in the longitudinal direction, and the cover material 7 is displaced or detached.

  In particular, the cover material 7 does not extend over the entire length in the vertical direction, but has a predetermined length that is the same length as the vertical direction of the exterior material 2 so as to have an uneven pattern having the same appearance as the exterior material 2. When the construction is made such that a plurality of cover materials 7 having a length are arranged in the vertical direction, there is a possibility that the cover material 7 moves further and comes off.

In order to prevent this, there is also provided a device in which a fixing tool such as a nail is driven into the exterior material 2 from the surface of the cover material 7 to secure the cover material 7 to the exterior material 2 (for example, see Patent Document 1).
