Is opened to expose the upper surface of the nut 6.
In this case, a cylindrical biting body 16 is cut and raised at the tip side of the cross-shaped mounting piece 4 of the mounting member 7 to protrude therefrom.
This biting body 16 bites into the wall material main body 2 and is integrated. In this case, the tip of the bite body 16 is expanded to increase the integrity. The left and right mounting members 7, 7 on the lower side are located inside the left and right mounting members 7, 7 on the upper side, and do not interfere with the mounting members for the upper and lower wall members. Like that.

The nut 6 has a screwing piece 1 of a fixing piece 9 having a structure in which a long metal fitting is deformed on the crank by retrofitting.
1 is fixed using screws 10. The screwing piece 11 extends in the opposite direction to the fixing piece 9 via the bent piece 14, is fitted into the hole 8 and contacts the nut 6, and has a hole 12 through which the screw 10 penetrates. . At the free end side of the fixing piece 9, there is a fastening hole 15 through which a wall fastening screw 13 penetrates.

As shown in FIG. 7, a building wall material 1 having such a configuration is obtained by adding a natural zeolite sand to a concave portion 21 of a lower mold 20 with an inorganic adhesive, cement and water and mixing them.
