本発明はタイル張付模様を有する建築板の製造
方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a building board having a tiled pattern.
タイル張付模様を有する無機質建築板を製造す

ーメントが作用すると溝の部分で曲げモーメント
の大部分が負担されることとなり、溝部分での曲
げモーメントの集中が避けられない。 In order to produce an inorganic building board with a tiled pattern, it is necessary to compression mold the surface of an uncured inorganic board into a tiled pattern, and then cure and harden the molded product. In the building board manufactured in this way, the grooves between the tiles are as shown in Figure 1.
The part corresponding to tile piece 2' is compressed more deeply than the part corresponding to tile piece 2', has a higher density, and has a larger Young's modulus. Therefore, when a bending moment acts on this building board, most of the bending moment is borne by the grooves, and concentration of the bending moment in the grooves is unavoidable.

トの集中は不利である。 However, it is ideal for a building board to bear the external force acting on it as uniformly as possible over the entire building board, and concentration of bending moments in the grooves is disadvantageous.

縮成形することを特徴とする方法である。 The method for producing a building board according to the present invention is a method capable of alleviating the above-mentioned disadvantages, in which a pattern having grooves between a large number of rectangular convex portions is compression-molded on the surface of an uncured inorganic base plate, and the molded body is In manufacturing an inorganic board that undergoes curing and hardening, this method is characterized in that the surface of the rectangular convex portion is also compressed into an uneven shape.
以下、図面により本発明を説明する。 The present invention will be explained below with reference to the drawings.

建築板を得る。 In FIG. 2, reference numeral 1 indicates an uncured inorganic original plate, and for example, an asbestos cement raw plate obtained by a papermaking method can be used. Reference numeral 2 denotes a press for patterning, and the above-mentioned asbestos cement raw plate 1 is carried into this press 2, and as shown in FIG.
A pattern having grooves b, b... between a... and irregularities, for example, scattered concave portions c, c... is formed on the surface of the rectangular convex portions a, a.... Reference numeral 3 denotes a curing device, such as an autoclave, into which the compressed board material is transported and then cured to obtain a building board.
上記において、模様付けには模様付けロールを

アから取出し、養生すればよい。 The invention can also be applied to the dry production of asbestos-cement boards, in which case the asbestos-cement powder raw material is deposited on a belt conveyor, this deposited raw material is stratified by leveling rolls, and by dripping water. An uncured asbestos cement strip obtained through various steps such as wetting the layered raw material is patterned using a patterning roll in the same manner as described above, cut into regular lengths, taken out from a belt conveyor, and cured.

い。 As shown in FIG. 4, the pattern of the above-mentioned pattern according to the present invention has a square convex surface portion a1 and a rectangular convex surface portion a2 having an area twice that of the square convex surface portion as one unit A of the pattern. It is preferable that the units are shifted by the length of one side of the square convex portion between the upper and lower rows, and a pattern is provided with continuous vertical grooves B, . . . .

When the patterned building boards shown in FIG. 3 are joined together, it is possible to avoid design inconsistency between the building boards as shown within the dotted line frame in FIG. 5B.
本発明に係る建築板の製造方法においては、上
述した通り、未養生原板の表面に多数の方形凸面
部間に溝を有する模様を圧縮成形する場合、方形
凸面部も凹凸状に圧縮しているから、凸面部の材
料密度を溝部の材料密度によく近ずけることがで
き、凸面部と溝部とのヤング率の相違を効果的に
小さくできる。 In the method for manufacturing a building board according to the present invention, as described above, when compression molding a pattern having grooves between a large number of rectangular convex portions on the surface of an uncured original board, the rectangular convex portions are also compressed into an uneven shape. Therefore, the material density of the convex surface portion can be closely approximated to the material density of the groove portion, and the difference in Young's modulus between the convex surface portion and the groove portion can be effectively reduced.
特に、材料が繊維混合セメントであれば、凸面
部での脱水不足を防止でき、材料分離による凸面
部の強度低下、ヤング率低下を排除できる。 In particular, if the material is fiber-mixed cement, insufficient dehydration in the convex portion can be prevented, and reductions in strength and Young's modulus of the convex portion due to material separation can be avoided.
従つて、本発明によれば、方形凸面部と溝部と
によく均衡して曲げモーメントを負担させ得るタ
イル張付模様の無機質建築板を得ることができ
る。 Therefore, according to the present invention, it is possible to obtain an inorganic building board with a tiled pattern that allows the rectangular convex surface portion and the groove portion to bear a bending moment in a well-balanced manner.
