However, the composite building material disclosed in Patent Document 1 is provided with dovetails on the extrusion-molded cement board and hooks the finishing material, so the workability is good, but what can be attached is the back of the finishing material such as tiles and stones. It will be restricted to what was provided with the rib (convex part 13) for hooking to the side. Further, since the exterior finishing material such as a tile is fixed with a rib, strength is required, and this structure cannot be used for a large tile or the like. In addition, once installed, it has been difficult to replace if it is damaged.
On the other hand, the attachment structure of the thick exterior material disclosed in Patent Document 2 uses a hollow portion of the extrusion-molded cement board to attach a finishing material. Since it was installed and tightened, the water that entered the space between the exterior finish and the extruded cement board entered the hollow part from the hole, and also entered the indoor side by making a hole in the surface. There was a fear. Further, this hole may cause a decrease in performance as an outer wall, for example, causing a decrease in heat and sound insulation. Once installed, it is difficult to replace it when it is damaged. In addition, cost increases due to drilling were inevitable.

In the mounting structure according to the present embodiment, the extrusion-molded cement board 41 is attached to the building frame so that the extrusion direction of the extrusion-molded cement board 41 is in the horizontal direction (also referred to as so-called “horizontal tension”). As shown in FIG. 4, the extruded cement board 41 is formed with a convex portion 55 on the upper side and a concave portion 57 on the lower side, and the extruded cement plates 41 and 41 adjacent to each other on the upper and lower sides are formed with the convex portion 55 and the concave portion. 57 and are connected. A gasket G and a sealing S are provided at the joint formed between the extruded cement plates 41 and 41.

  On the upper portion of the surface 59 of the extrusion-molded cement board 41, there is provided an upper ridge 63 formed by a hooking surface 61 that extends in the extrusion direction and is integrally formed, and whose upper end surface is inclined downward toward the surface 59. ing. Further, a lower ridge 67 is formed at the lower portion of the surface 59 of the extrusion-molded cement board 41 and is integrally formed by extending in the extruding direction, and the lower end surface is formed by an inclined surface 65 that is inclined upward toward the surface 59. Is provided. The hook surface 61 and the inclined surface 65 are formed so that the angle α formed with the surface 59 is about 50 degrees.

  An exterior finishing material 69 is attached to the surface 59 of the extrusion-molded cement board 41 using the upper ridge 63 and the lower ridge 67. The exterior finishing material 69 is attached via an attachment 71 that is a relay attachment plate. The attachment 71 is formed with a hooking piece 73 bent at an acute angle that engages with the hooking surface 61 of the upper ridge 63 along the upper side, and the lower part is screwed to the inclined surface 65 of the lower ridge 67.

  In the present embodiment, the attachment 71 is formed in a strip shape that is long in the vertical direction. The attachment 71 is fixed to at least two lateral positions on the back surface of the exterior finishing material 69. In the present embodiment, as shown in FIG. 2, five attachments 71 are fixed to the back surface of the exterior finishing material 69. The size of the attachment 71 is created in accordance with the size of the extruded cement board 41. The bolts 75 are fastened according to the width of the extruded cement board 41 at intervals of approximately 300 to 600 mm. Further, the attachment 71 and the exterior finishing material 69 are directly fastened with bolts or anchors.

  As the exterior finishing material (surface decoration material) 69, stones, tiles, solar battery panels, greening panels, and the like can be attached, but the exterior finishing material 69 that can be attached by the attachment 71 is not limited thereto.
