１５か配筋１４に取り付けられている。As shown in FIG. 1, after setting the reinforcing bars 4 assembled with the main reinforcing bars 12 and mesh bars 13 in the molding frame 11 using a support device (not shown), insert the through holes for the wiring or piping to be formed. A rod-shaped foamed resin member 15 made of foamed polystyrene is fixed to the reinforcement 14 along the pattern with a wire or the like. In this embodiment, two rod-shaped foamed resin members 15 are attached to the reinforcement 14 so as to be bent in a right angle direction from the - side of the reinforcement 14 to the adjacent - side.

１７が形成される。Next, after removing the molded panel from the formwork 11, the panel is placed in an autoclave (not shown), for example.
The lightweight aerated concrete panel 16 of this example shown in FIG. The rod-shaped foamed resin members 15 are melted at the high temperature of the autoclave, and after these rod-shaped foamed resin members 15 are melted, wiring or piping insertion holes 17 are formed in a pattern that follows the shape of the rod-shaped foamed resin members 15 that have been placed. It is formed.

容易である。According to the manufacturing method of the lightweight aerated concrete panel 16 of the above embodiment, by performing normal autoclave curing, the insertion holes 17 are formed in a pattern that follows the shape of the rod-shaped foamed resin member 15 fixed to the reinforcement 14 after autoclaving. Since the foamed concrete panel 16 is formed in a lightweight aerated concrete panel
The work for forming the wiring or piping insertion hole 17 therein is easy.

Because it has excellent flexibility and can be bent into any shape, the wiring or piping insertion hole 17 has a complicated curved pattern.
However, it can be easily formed.

気泡コンクリートパネル１６を安価に提供できる。Furthermore, in this embodiment, since expanded polystyrene having an expansion rate several tens of times higher is used as the rod-shaped foamed resin member 15, the amount of molten slag of the rod-shaped foamed resin member 15 after melting in an autoclave is extremely small. After melting, an insertion hole 17 with a large cross-sectional area can be formed. Moreover, since expanded polystyrene is relatively inexpensive, the lightweight cellular concrete panel 16 can be provided at low cost.
