を施して製造している。b. Conventional technology Generally, when manufacturing ALC plates, multiple rebar cages are hung vertically at regular intervals using a set frame and a set rod in the form, and the siliceous and calcareous raw materials are placed in the form. A raw material prepared by adding metallic aluminum powder to a main slurry is injected. Then, after a certain period of time, after the raw material reaches a semi-cured state, it is demolded, and this is vertically cut with a piano wire or the like into a plurality of plate bodies, and finally subjected to autoclave curing to be manufactured. There is.

にある。d. Means for Solving the Problems The present invention is directed to a plurality of sets of paired set rod support members provided with set rod support portions at regular intervals in the vertical direction and arranged to face each other at predetermined intervals, and to form a set rod. A set bar is inserted between the support tools to hold a plurality of rebar cages horizontally and at regular intervals in the vertical direction, then these rebar cages are placed in a mold to inject the raw materials and semi-cure. After molding into the state, demolding,
After removing the set rod support and the set rod, the molded product is cut at regular intervals, divided into plates with embedded reinforced baskets, and these plates are steam-cured to form ALC plates. is there.

ート７を一定間隔で溶接等により装着してある。In both of the above figures, 1 is a formwork, 2 is a rebar cage, and 3 is a set rod supporter arranged at regular intervals along the inner surface of the formwork 1. This is the vertical direction as shown in FIG. The holes 4 are provided as set rod supporting portions at regular intervals.
5 are corresponding holes 4 between the set rod supports 3 facing each other.
Is a set rod inserted through the side wall of the rebar cage 2 and supported in a horizontal state by inserting the side face of the rebar cage 2 at regular intervals. As shown in FIG. 5, the rebar cage 2 is formed in a thin box shape by welding the vertical bars and the horizontal bars in a grid pattern, and a hole 6 for inserting the set bar 5 is formed on the side surface thereof. The plates 7 are attached at regular intervals by welding or the like.
次に、ALC 版の製造方法を説明する。Next, a method for manufacturing the ALC plate will be described.
