の設備投資額の低減も可能になる。Next, a method for forming lightweight aerated concrete panels using this forming formwork 1io will be explained. As shown in FIG. 2, the fixed bin 21 is connected to the side frame member 12 and the guide member l.
4 through the holes 20A and 20B, and the side frame member l2
A lightweight aerated concrete slurry 22A is poured into the formwork W10 in which it is fixed. Thereafter, the slurry 22A is solidified after a predetermined period of time. During this coagulation process, an expansion force is generated in the slurry 22A due to heat generation, so a force is exerted to press the side frame member I2 in the left and right direction.
After fixing the fixing pin 2l, insert it into the holes 2OA and 20B.
Pull it out and release the fixed state. Immediately after releasing this fixed state, the both side frame members 12 are loaded with the slurry 2 mentioned above.
Due to the pressing force due to thermal expansion of 2A, the cylindrical convex portion 16 rotates left and right while being guided by the guide groove l9 and opens.
The formwork device 10 for the round shape is dismantled. After this, the panel 22B is pressurized in an autoclave and steam-cured, thereby making the panel 22B a complete product.
obtain. As described above, according to this embodiment, after the panel 22B is formed, the frame members 12 on both sides are opened to the left and right by the pressing force caused by the thermal expansion of the slurry 22A, and the formwork device 10 for forming the formwork is naturally dismantled. Therefore, the panel 22B can be demolded without requiring any special equipment or driving force for disassembling the formwork device. Therefore, the formwork W10 for Kaigata
It will also be possible to reduce the amount of capital investment.
