この発明は、木片セメント板を製造する際に用いる木片
セメント板の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for manufacturing a wood cement board used in manufacturing a wood cement board.
従来、木片セメント板の製造は、セメントペーストに木
片を混入して木片入りのセメントペーストを形成し、こ
の木片入りのセメントペーストを型枠に流み込み、硬化
させることにより形成していた。Conventionally, wood chip cement boards have been manufactured by mixing wood chips into cement paste to form a cement paste containing wood chips, and pouring this cement paste containing wood chips into a formwork and hardening it.
しかし１、この方法では、型枠内にセメントペーストを
流し込んだ際に、木片が型枠の化粧目地を形成するため

の表面まで充分に行き渡らず、硬化したときに木片が表
面に露出して外観を損なったり、木片位置の目地部の角
部に窪みが生して仕上がりが悪くなったりするという問
題が生じていた。However, 1. With this method, when cement paste is poured into the formwork, if the wooden pieces come into contact with the protrusions provided to form the decorative joints of the formwork, the cement will reach the surface of the formwork. Problems have arisen in that the wood chips do not spread sufficiently, and when the wood chips harden, they are exposed on the surface, spoiling the appearance, and the corners of the joints where the wood chips are located are dented, resulting in a poor finish.
したがって、この発明の目的は、外観および仕上がりの
向上が図れる木片セメント板の製造方法を提供すること
である。Therefore, an object of the present invention is to provide a method for manufacturing a wood cement board that can improve the appearance and finish.

。The method for manufacturing a wood chip cement board of the present invention is a method for manufacturing a wood chip cement board with wood chips mixed therein, in which cement paste is poured into a mold, and the wood chips are scattered and laminated on the cement paste. It is formed by pressing the top surface of this piece of wood and then hardening it.

板の表面の目地の輪郭を明瞭に仕上げることができる。According to the method of this invention, after pouring cement paste into a mold, wood chips are scattered and laminated on the top surface of the cement paste, and the top surface of the wood chips is pressed to form a wood chip cement board. The cement paste penetrates and no wood chips are exposed on the surface of the hardened wood cement board. Therefore, the appearance is not impaired, and since the wood pieces are not exposed on the surface, the outline of the joints on the surface of the wood piece cement board can be clearly finished.
この発明の一実施例を第１図に基づいて説明する。 An embodiment of the present invention will be described based on FIG.
型枠ｌは、金属やプラスチック等からなり、セメントペ
ースト２が流し込まれる側には目地形成用の突起１ａが
一定の間隔で形成しである。The form l is made of metal, plastic, etc., and has protrusions 1a for forming joints formed at regular intervals on the side into which the cement paste 2 is poured.
セメントペースト２は、型枠１に流し込む際にはゲル状
となるように調合してあり、流し込んだときに型枠１の
形状に沿って固着される。The cement paste 2 is prepared to be gel-like when poured into the formwork 1, and is fixed along the shape of the formwork 1 when poured.
木片３は、化学薬品処理を施すことにより硬質化、鉱物

の順番で散布される。The wood piece 3 has been hardened and mineralized by chemical treatment to improve waterproofness and the like. This piece of wood 3 consists of one formed into coarse grains and one formed into fine grains,
The cement paste 2 is sprinkled on the upper surface in the order of fine particles, coarse particles, and fine particles.
この実施例による木片セメント板５の製造手順を説明す
る。型枠ｌを用意する。この型枠１にゲル状に調合した
セメントペースト２を流し込む。The manufacturing procedure of the wood chip cement board 5 according to this example will be explained. Prepare formwork l. Cement paste 2 prepared in gel form is poured into this mold 1.

押え板４側に回り、木片３の間に浸透する。押え板４を
取り除いてセメントペースト２を硬化させる。硬化後に
型枠１を取り外して木片セメント板５が形成される。First, on the top surface of this cement paste 2, fine-grained wood chips 3 are applied.
, then coarse-grained wood chips 3 are sprinkled, and fine-grained wood chips 3 are again sprinkled. A press plate 4 is set on the top surface of the wood piece 3 and pressed. At the same time as each piece of wood 3 sinks into the cement paste 2 by pressing, the cement paste 2 turns to the holding plate 4 side and penetrates between the pieces of wood 3. The press plate 4 is removed and the cement paste 2 is allowed to harden. After curing, the formwork 1 is removed and a wood cement board 5 is formed.
この実施例の構成によれば、型枠１内にセメントペース

ができる。According to the configuration of this embodiment, after cement paste 2 is poured into a formwork 1, fine-grained and coarse-grained wood chips 3 are alternately scattered and laminated on the top surface of the cement paste 2, and the top surface of the wood chips 3 is held down. Since the wood cement board 5 is formed by pressing with the board 4 and then hardening, the cement paste 2 penetrates between the wood chips 3, and when hardened, the wood chips 3 are exposed on the surface of the wood cement board 5. Therefore, the outline of the joints on the surface of the wood cement board 5 can be clearly finished. Furthermore, since the wood pieces 3 are not exposed on the surface of the wood piece cement board 5, rainwater etc. do not enter into the inside of the wood piece cement board 5 from the wood piece 3 portion, and waterproofness can be improved.
