[0039]

In the structure for fastening a building board according to the present invention, a ventilation layer can be sufficiently secured between the building side and the building board without using a furring strip (that is, even if it is directly attached). Therefore, the work for attaching the furring strip can be omitted, and the fastening work can be largely labor-saving. In addition, when a surface load is applied to the back side of the fastened building board, the load is not mainly due to the upper and lower horizontal side edges of the building board, but is mainly fixed to the back side of the building board. Since they are carried by the engaging portions of the attaching members, they do not act on the joining portions (lower solid portion and upper solid portion) formed on the upper and lower horizontal side edges of the building board. Therefore, it is possible to avoid damage to the joint part of the building board. Further, the fixing of the building board fastening member to the back surface of the building board is performed in the factory, so that the construction board fastening work at the construction site is surely labor-saving.
