Description

  The present invention relates to an exterior structure used for an outer wall of a building such as a building.

  As one form of the outer wall of a building, there is one in which an exterior panel formed in a shallow box shape that is opened from a thin metal plate such as aluminum is arranged side by side in the vertical and horizontal directions. The exterior panel is provided with protruding mounting pieces on the edge of the housing, and the exterior panels are arranged side by side with the mounting pieces overlapped, and screwed to a long base material fixed to the housing. In order to conceal the screw and to ensure water-stopping, a sealing material is filled between the exterior panels, and joints between the upper and lower exterior panels and between the left and right exterior panels are vertically and horizontally. It is formed.

As mentioned above, it takes time to fill the joint with the sealing material, and since the sealing performance is deteriorated due to aging of the sealing material, the structure is not filled with the sealing material in recent years. It has been demanded. As a conventional construction method for this purpose, Patent Document 1 discloses that a fireproof molded plate is attached to the outside of the casing, a base material is attached on the fireproof molded plate so as to be adjustable, and the side of the exterior plate (exterior panel) adjacent to the left and right The flange-shaped presser portions formed in the part are fixed to the base material by joint presser materials. The joint retainer is composed of two members, a long main body having a U-shaped cross section and a lid body engaged and attached to the main body. In this construction method, the flange-shaped presser portions of adjacent exterior plates are pressed and fixed together with joint retainers, so that when installing the exterior plates, the exterior plates arranged in the vertical direction and the left-right direction are attached to the top of each exterior plate. Since it is necessary to temporarily fix the rising portion formed on the base material with screws, it is troublesome to attach the exterior plate. The joint retainer is composed of two members, a main body and a lid. Since the lid must be further attached after only the main body is screwed to the base material first, it takes time to install. Moreover, the water stoppage by the joint presser material is not perfect, and there is a high possibility that rainwater will infiltrate from the intersection of the vertical joint and the horizontal joint.
