And a long decorative plate in which an outward folding end is formed above a fixing portion having an appropriate width capable of contacting a vertical surface of a support material, and a rising surface is formed outward downward. A length formed by forming an insert piece with a short width folded back upward at the inner end of the upper fixing portion and the rising surface which is located opposite to the rising surface and has a rising width slightly smaller than this rising width. A fixed length fixed part formed by forming a groove-shaped insertion part for elastically sandwiching the insertion piece under the fixing part of the scale-like decorative plate and the fixing seat part that is fixed by overlapping with the fixing part And a plurality of fixing members are abutted in a row at an appropriate interval on the outer surface of the upper portion of the fixing portion. Both of them are fixed to a support member, insert pieces are inserted into the inserting portions of these fixing members, and a slight gap is maintained between the inserting pieces and the fixing portion to form the structure of the fixing portion of the exterior wall. It is characterized by.

It is configured as a pair of separate members separated from 90. In this case, the fixing surface 54 of the plate upper fixing portion 50 and the plate lower fixing portion 90 are fixed to the bolt 25 which is integrally formed beforehand by embedding or welding in the upper and lower portions of the back surface of the exterior material 24 of a ceramic plate or other appropriate material. The surfaces 93 are fixed to each other, and then the exterior material 24 may be attached to the support material 3 by the fixing member 13 as described above.

(Effects of the Invention) As described above, according to the present invention, the fixing member 13 is used to insert and hold the lower end portion of the exterior material, and at the same time, the upper end portion is bolted to form the exterior wall. be able to. In this way, a simple and efficient construction can be realized by the combination of the simple insertion work and the reliable bolt fixing work, while the exterior material is not rattled and is stably and reliably fixed without fear of coming off. According to this configuration, even a wide-width exterior material or a heavy exterior material can be applied without any trouble. In addition, the fixing member maintains the air permeability inside and outside the exterior material and functions as an exterior structure having an open structure.

In this case, if the upper plate fixing portion and the lower plate fixing portion are configured as in the above-described embodiment, the air (wind) entering from the outside of the exterior material into the inside will be the insertion piece at the lower end and the fixing portion at the upper end. From the gap that was extremely narrowed by the contact surface part of the plate, it spreads all at once to a wide space inside the plate lower fixing part inside and the pressure is reduced at the same time, and at the same time the outer end of the upper end prevents upward blowing up. Since it has an open structure, it is possible to effectively prevent rain from blowing into it.
