ある。In order to achieve this object, the present invention provides an A with a curved outer surface.
In the method for manufacturing an LC corner plate, a rectangular mold having a recess with a semicircular cross section in the mold and vertically divided into two parts at the center in the longitudinal direction is prepared by creating at least a slight gap between the divided surfaces. ALC raw material slurry is then injected into the entire surface of the mold, and when it becomes semi-hardened, it is cut at the upper surface of the mold or at the upper surface of the mold and the dividing surface,
Each block is formed into a block with a semicircular or quarter-circular cross section, and then cured in an autoclave to be cured.

とが出来る。FIG. 1 is a cross-sectional view showing an example of manufacturing an ALC corner plate by placing a mold in a mold and incorporating reinforcing reinforcing bars according to the method of the present invention. As shown in FIG. 1, a rectangular mold having a recess 2 with a semicircular cross section is placed in a mold 1 which is normally used for manufacturing ALC, and the perspective view thereof is shown in FIG. Mold 4 divided into two vertically at the center part 3 of the direction
．． Two sets of reinforcing bars 6 and 6' are placed in the mold 1 so that the part of the dividing surface 3 slightly opens the gap 5, and reinforcing reinforcing bars 6 and 6' are placed in the mold 4.
, 4', supported by a support rod 8 inserted through a bridge 7 that crosses over the formwork 1, and then spreads the ALc raw material slurry over the entire surface of the formwork 1. After a certain period of time has elapsed after the injection and foaming, when the raw material is in a semi-hardened state, the support rod 8 is rotated 90' as necessary to remove it together with the bridge 7, and the formwork 1 is removed, following the chain line A-- shown in FIG.
After cutting horizontally along the upper surface of the mold 4.4' at A, and then vertically cutting along the dashed line B-B, the mold was cured by autoclave curing to harden the flat surface on the mold 4,4'. A
After removing the LC, by taking out the hardened AI, 0 from the mold recess, it is possible to obtain an ALC corner plate with a semicircular cross section as shown in Figure 3a and a quarter circular cross section as shown in Figure 3S. I can do it.
鋳型４，４′が２分割されて、型枠内に僅かに間隙を開
けて配置するのは、垂直切断用の例えばピアノ線が円滑
に通過出来るようにするためであって、断面半円形のコ
ーナー版のみを製造するのであれば鋳型を２分割する必
要もなく、間隙をあけて配置することも不要である。The reason why the molds 4 and 4' are divided into two parts and placed with a slight gap in the mold is to allow vertical cutting, for example, piano wire, to pass through smoothly. If only corner plates are to be manufactured, there is no need to divide the mold into two parts, and there is no need to arrange them with a gap between them.
鋳型４，４′の凹部２の断面形状も必ずしも半円形でな
くてもよく、必要に応じて内面に例えば凹凸を持たせる
こともできる。The cross-sectional shape of the recesses 2 of the molds 4, 4' does not necessarily have to be semicircular, and the inner surface can be made uneven, for example, if necessary.
型枠内へ鋳型を配置する組数は製品の寸法によって自ず
から定まる。The number of molds to be placed in the mold is naturally determined by the dimensions of the product.
以上詳細に説明したように本発明によれは比較的簡単な
設備で外面が曲面をなし、断面形状が半円形又は四分一
円形のＡＬＣコーナー版が容易に製造できるので、硬化
後のＡＬＣを切断加工することによるＡＬＣスクラップ
の発生や切削刃の磨耗の問題もなく、また曲面上に模様
がついたコーナー版も簡易に製造することが出来るので
、その実用的効果は大なるものがある。As explained in detail above, according to the present invention, an ALC corner plate with a curved outer surface and a semicircular or quarter-circular cross section can be easily manufactured using relatively simple equipment. There is no problem of generation of ALC scrap or wear of the cutting blade due to this, and corner plates with patterns on curved surfaces can be easily manufactured, so the practical effects are great.
