FIG. 7 is a diagram illustrating a configuration of another embodiment.

In FIG. 1, a molded finishing material 1 is made of an artificial molded body containing an aluminum component, and has a function of being attached to a base wall constituting an outer wall surface or an inner wall surface of a building to decorate the wall surface. are doing. For the molded finish 1, a material corresponding to the target molded body is charged into a mold (not shown), and then subjected to a process (for example, heating or pressing) according to the material, molded, demolded, and It is manufactured by performing processing such as cutting and polishing as necessary.

A predetermined number of pilot holes are drilled at predetermined positions on the back surface of the finished surface of the molded material 1, for example, at one or more locations in the vicinity of the upper and lower sides. A female screw part is provided for the A bolt is screwed into the female screw portion via an adhesive so that the formed finish can be firmly supported.

An aluminum component is indispensable as a component of the formed finishing material 1 in which a prepared hole is made at a predetermined position on the back surface of the finished surface of the formed finished material 1 and then a screw is cut with a tap. And silica-based inorganic particles were kneaded and press-molded.
The use of an aluminum crushing tip provides the inherent stickiness and elasticity of the metal, enabling cutting and tapping. Conventionally, screw processing with a tap cannot be performed on a panel made of stone, glass, concrete, or the like. However, as described in the present embodiment, the screw processing can be performed for the first time by mixing a grinding chip of aluminum.

In the present embodiment, the adhesive may be of any type, such as epoxy-based, acrylic-based, urethane-based, etc., and may be selected according to the site of use.

An example of a method of manufacturing the formed finish 1 having the above-described structure will be briefly described. First, a pulverized chip of aluminum and silica-based inorganic particles, which are raw materials for a formed plate, were kneaded and put into a mold frame corresponding to the plane dimensions and thickness of the formed finish 1 and formed by high-pressure pressing. After that, it was released from the mold, cut into a predetermined size, and subjected to processing such as polishing to produce a molded finish 1. Thereafter, a pilot hole was provided at a place where the mounting bolt was provided, and thread cutting (screw cutting) was performed with a tap. The use of an aluminum crushed tip provides the inherent stickiness and elasticity of the metal, enabling cutting and tap cutting.

In the present embodiment, the finishing material can be attached to the wall material by using the bolt by the rear hole and the tap cutting as described above, and the formation of the hole in the fore-face (the width of the fore-face) (The smaller the size of the hole, the more difficult this hole forming operation) becomes. Therefore, it is possible to keep the thickness of the finished material 1 in the range of 8 to 25 mm. The plane size of the formed finish 1 is about 300 to 1200 mm.

Further, in this example, four mounting bolts are provided near the upper and lower sides of the molded finish 1 and on both sides in the left-right direction. However, the number of mounting bolts provided on the formed finishing material 1 should be set according to conditions such as dimensions and weight of the finishing material 1.
