Abstract

PURPOSE:To make it possible to easily cut in certain dimensions and separately eliminate the need to remove the overflowing of material by a method wherein inorganic board material is fixed to tiles by pressure with a press and, at the same time, overflown material is removed with cutters and, in addition, deaerating holes are bored on the bottom face of a tile form and joint parts are made of elastic material. CONSTITUTION:Cement-based board material 6 is extruded with an extruder of cement- based kneaded material, for example, so as to be placed on a tile form 1, which is conveyed, and cut properly in the predetermined lengths. By pressing the board material 6 under its soft state at the predetermined position, the board material is fixed to tiles 3 by pressure and, at the same time, overflown material is removed with cutters C. Next, the resultant board material is subjected to the predetermined curing and hardened and stripped so as to allow to obtain a tiled cement-based building material, in which the tiles 3 and the cement-based board material 6 are made into an integral body. By the way, since deaerating holes 1B are bored on the bottom face of the tile form 1, deaeration can be possible at pressing. In addition, joint parts 7 are made of elastic body so as to absorb the fluctuation in the dimensions of tile and, at the same time, to prevent cement from going round to the front surface side of the tile 3 at pressing.

A tile support plate 25 is installed on the roller 24, and on the lower surface of the running start side S of the endless belt 23.
A tile supply device 26 is disposed on the upper surface 23A of the endless belt 23 corresponding to the tile support plate 25, and is directed diagonally upward toward the endless belt 23 at the edge of the tile support plate 25 along the belt running direction (arrow p). An extruder 28 for extruding the inorganic kneaded material 27 is provided, and a discharge opening 2 of the extruder 28 is provided.
A tile 21 is placed on the upper surface of the endless belt 23 corresponding to 8A.
A pressure plate 29 is provided to press the belt 23 together with a pressure plate 29, and a conveyor belt 30 that supports the extruded kneaded material 27 is provided on the side of the belt running direction from the presser machine 28, and on this conveyor belt 30, The endless belt 23 is bent upward (arrow q) so as to return the tiles 21, leaving behind them. 31 is a cutter,
This is for cutting the shaped building material G with tiles into predetermined lengths.

Next, the operation of the conventional device described above will be explained.

First, the endless belt 23 and the conveyor belts 1 and 30 are driven at a constant synchronous speed, and the endless belt 2
The tiles 21 are supplied to each of the 3 tile fitting holes 22 . At this time, the tiles 2 fitted to the endless belt 23
1... are prevented from falling off by the tile support plate 25, and are transported together with the endless belt 23. Next, the inorganic kneaded material 27 is extruded and supplied from the bottom surface of the endless belt 23. Further, since the endless belt 23 and the tiles 21 are supported by the pressure-resisting plate 29, they can withstand extrusion pressure, and a dense extrusion eyebrow of the inorganic kneaded material is formed on the lower surface of the endless belt 23. At this time, tile 21
As a result of the upper surface and the upper surface of the endless belt 23 being flush with each other, only the tiles 21 are embedded in the inorganic kneaded material by the difference in thickness with respect to the endless belt 23. Finally, only the endless belt 23 is guided by the rollers 24 and the molded product G
It moves away from. At this time, tiles 21 . . . are embedded in the surface of the molded product G, and joints H having a depth corresponding to the thickness b of the endless belt 23 are neatly formed.

(Problems to be Solved by the Invention) In the conventional manufacturing of inorganic building materials with L-shaped tiles, it is difficult to cut them into uniform dimensions because of continuous production, and the dimensions of the tiles vary, so There were problems such as cement material protruding from products with specified dimensions.

Accordingly, an object of the present invention is to provide a method for manufacturing an inorganic building material with tiles that can be easily cut to a certain size and does not require separate removal of protruding material.

(Means for Solving the Problems) The method for producing tile inorganic building materials according to the present invention is characterized in that a large number of tile fitting recesses are arranged at predetermined intervals vertically and horizontally at fixed positions of the take-up barre 1, and the bottom surface thereof A tile frame with a large number of deaeration holes drilled therein and a joint-formed part made of an elastic body is placed on the tile frame, and the tiles are fitted into the recesses with the back side facing upward, and then these are pushed out by a conveying means. The inorganic plate that has been extruded and shaped from the extruder is taken over the tile frame and cut into a predetermined length, and is pressed at a fixed position by a pressing means to integrate the tile and the inorganic plate. The protruding material is removed and, finally, the prescribed curing is performed.

(Example) Examples of the present invention will be described below with reference to the drawings.

FIG. 1 is a process diagram showing a method for producing an inorganic building material with tiles, in which 1 shows a tile frame and 2 a pick-up pallet on which the tile frame 1 is placed. In the tile frame 1, a second

・ are inserted into each. The bow-cut barresoto 2 on which the tile frame 1 is placed is continuously or intermittently supplied to the extrusion line I5 by a conveying means, for example, a roller conveyor or a belt conveyor 4. 5 is an extruder for inorganic kneaded material, for example, cement-based kneaded material, and the tile frame 1 is transported.
A cement-based plate 6 is extruded and placed on top, and cut into a predetermined length as appropriate. Then, while the plate body 6 is still soft, it is pressed in a fixed position to press it to the tile 3, and the protruding material is removed by a canter C (FIGS. 4(A) to 4(C)). Next, a predetermined curing is performed, and after hardening, the mold is demolded to obtain a cement-based building material with tiles in which the tiles 3 and the cement-based board 6 are integrated.

Incidentally, a deaeration hole IB is provided in the bottom surface of the tile frame l (FIG. 3(A)), so that air can be removed during pressing (FIG. 3(B)).

In addition, the vertically and horizontally spaced parts around the tile fitting part IA, that is, the joint parts 7, are made of an elastic material to absorb variations in the tile dimensions, and also to prevent the cement from sticking to the tiles during pressing.
prevent it from going around to the surface side (Fig. 3 (C)'). Furthermore, if methyl cellulose is used in the extrusion mold, the extruded cement-based plate 6 will have the plasticity to easily flow into the joints 7 of the tile 3, and in addition, dewatering due to pressing can be prevented, so the plate 6 and Tile 3 are easy to integrate. In this way, after the prescribed curing, the cement-based board 6 and the tile 3
are completely integrated.

Incidentally, silica flour is mixed into the cement-based kneaded material to accelerate the reaction of cement, and reinforcing fibers such as bulp and alkali-resistant glass fiber are mixed in to reinforce the cement-based plate 6. Furthermore, by adding a coloring agent to the cement-based kneaded material, the joint areas can be colored.
