観を損なっていた。When it comes to large-sized products, such porous ceramic plates have a high strength and
It is necessary to reinforce with reinforcing bars such as flat laths, rebrass, and welded reinforcing bars, but if they are buried near the surface layer, the foam layer above the reinforcing bars and laths will be thinner than other parts, resulting in dents similar to the shape of the reinforcing bars and laths. This caused deterioration in the smoothness and aesthetic appearance of the product surface.

A method for manufacturing an integrated porous ceramic plate, in which reinforcing bars or lath nets are buried at a depth of at least 3 times the diameter of the reinforcing bars or the thickness of the lath net from the surface and at least 5 times the thickness of the reinforcing bars. It is characterized by

ラス網をつくる鉄板の厚さのことをいい、リブラスのば
あいリブの高さのことをいう。[Example] The manufacturing method of the present invention is characterized in that the reinforcing bars are buried deeper than a certain level. This constant depth varies depending on the type and shape of the reinforcing bars and the product thickness, but the present inventors found that
When embedding reinforcing bars at a depth of at least twice the thickness of the lath net and at least 5 layers, or at least 3 times the thickness of the lath mesh and at a depth of 5 layers or more, the surface of the ceramic plate after firing is It was discovered that the dents caused by reinforcing bars were eliminated, and the present invention was completed. Here, the thickness of the lath net refers to the thickness of the iron plate that makes the lath net in the case of flat laths, and the height of the ribs in the case of ribbed laths.

凹みが発生する慣れがある。If the embedding depth is less than 5111, it will be difficult to embed the reinforcing bars reliably with accuracy. Also, 3 of the reinforcing bar diameter
If the thickness is less than double or three times the thickness of the lath mesh, the foam layer above the reinforcing bars, etc. constituting the reinforcing bars is insufficient, and dents may occur due to the reinforcing bars.

It is possible to use a material welded to form a mesh of approximately ++ angle. Further, as the lath mesh, commercially available flat lath (diamond-shaped wire mesh), riblath (for example, angle lath LAS type manufactured by Nippon Fuelas Kogyo ■), etc. can be used.

とで行ってもよい。The reinforcing bars may be buried by charging the inorganic foam granules to a predetermined thickness, placing the reinforcing bars on top of the reinforcing bars, and then charging the inorganic foam granules on top of the reinforcing bars, or by burying the reinforcing bars in a hollow state. This may be carried out by supplying inorganic foamable granules onto reinforcing bars placed on the reinforcing bars.
