In such a mounting structure, the finishing panel is a stone, large tile, etc., and is a heavy object, so it is necessary to firmly support it. The method of construction is complicated if it is supported by a frame (a concrete wall that has been laid). In addition, as described in Patent Document 2 and Patent Document 3, when a finish panel is attached to a horizontal rail fastener on the surface of a wall panel, it is necessary to fix a hardware to the small edge surface of the finish panel. If it is not determined, the mounting height position of the rail fastener cannot be determined. Since the finish panel affects the appearance design, the specifications may be determined at the final stage. In such a case, the installation height position of the rail fastener is not determined until the end, making the construction complicated and prolonged. Cause inconvenience.
In addition, since the weight of the finish panel is supported by the wall panel, the load on the wall panel tends to be too large. This wall panel is originally a non-structural member. However, when the load is applied in this way, it is necessary to make a custom-made wall panel such as an excessively thick cross section in order to function as a structural member.

  The present invention has been made in view of such circumstances, and reduces the load on the wall panel, is economical without requiring an excessive cross section, and is easy to construct and can be constructed in a short period of time. An object is to provide a finishing panel mounting structure.

  According to the exterior finish panel mounting structure of the present invention, a plurality of wall panels arranged in the vertical plane direction are mounted on a building casing, and a plurality of arm members projecting on the outer surface of the wall panels include the casing. A vertical frame extending in the vertical direction on the outer surface of the wall panel is provided on each of the projecting ends of the arm members, and rail fasteners extending in the horizontal direction are provided on the vertical frames. A plurality of panels are provided at intervals in the length direction, and a plurality of finishing panels are attached to these rail fasteners in parallel with the wall panels.

  In this mounting structure, the finishing panel is not a wall panel, but is supported by a building frame via an arm member protruding from the outer surface of the wall panel. Therefore, the load burden on the wall panel is reduced. Moreover, since the rail fastener is disposed by the vertical frame provided on the arm member separately from the wall panel, the rail fastener can be disposed at an arbitrary height position after the wall panel is attached. Construction of wall panels can proceed without waiting for the final panel specifications to be determined.

In the exterior finish panel mounting structure of the present invention, it is preferable that the arm member is provided between adjacent wall panels.
The arm member can be projected without forming a through-hole or the like on the panel surface of the wall panel, and construction is easy.

In the exterior finish panel attachment structure of the present invention, the rail fastener may be attached to the vertical frame so as to be swingable about an axial center along the projecting direction of the arm member.
Even when the finished panel is displaced due to vibration during an earthquake or the like, the rail fastener can follow the displacement and maintain the soundness of the mounting structure.

  According to the exterior finish panel mounting structure of the present invention, since the weight of the finish panel is supported by the frame of the building by the arm member, the load load on the wall panel is reduced, so that the structural performance of the wall panel is more than necessary. There is no need to raise it, and the vertical frame provided on the arm member allows the rail fastener to be placed at an arbitrary height position, so that the construction of the wall panel can proceed without being affected by the specification of the finished panel. It is possible to make the entire construction easier and shorten the construction period.
