[Effect of device]

In the present invention, since the side portion of the connecting piece of the connecting metal fitting is inserted into the connecting groove of the side end surface of the wall material, the connecting metal fitting is not exposed to the outside, and the cutout portion of the wall material is not exposed. Since the side end surface is brought into contact with the lateral portion of the fixing piece of the connecting metal fitting and the side end surface is brought into contact with the vertical portion of the fixing piece, the back surface of the wall material can be attached in close contact with the base of the wall, and furthermore, the connecting metal fitting of the connecting metal fitting can be attached. The connection piece and the fixed piece can be installed simply by inserting them into the connection groove of the wall material and fixing them to the wall foundation, and although the workability is excellent, the wall material is relatively simple in structure and easy to manufacture. Moreover, the rounded corner portion on the surface side of the side end portion of the wall material makes it possible to obtain a thick appearance in which the joint portion is a curved groove, and the side end surface of the wall material is Since the part on the back side of the connecting groove abuts on the vertical part of the fixing piece of the connecting fitting, the part of the side end surface on the surface side of the connecting groove does not abut on the adjacent wall material. Therefore, the corner portion, which is thin and weak due to the rounded shape, is not cracked or chipped due to contact with another member. In addition, since the connecting groove along the longitudinal direction is formed on the side end surface of the wall material which is wholly integrally formed of the extruded cement product by aligning it to the front side in the thickness direction of the wall material, there is a notch on the back surface. Although the part is formed, the connecting groove is offset to the front surface side, the back side can be made thicker than the connecting groove, and it can be firmly held by the connecting metal fitting inserted in the connecting groove. However, there is an advantage that a crack does not occur from the connecting structure and is not destroyed. That is, the present invention is a wall material that is integrally formed of an extruded cement product as a whole, and the corner portion on the surface side has a rounded shape, and the joint portion has a rounded shape to give a thick appearance, Moreover, the notch is formed on the back surface of the wall material, the horizontal part of the connecting metal fitting is inserted, and the wall material is attached by pressing it firmly without floating on the base,
Then, in order to insert and connect the connecting piece to the connecting groove formed in the inner part of the rounded portion, by offsetting the connecting groove to the front surface side, the unexpected thickness of the back side of the connecting groove is compensated, The feature is to avoid crack fracture.
