本発明は、建築用の外壁に用いる軽量複合板の製造方法
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 lightweight composite boards used for architectural exterior walls.

製法が提案されている。(Prior art) Conventionally, the manufacturing method for composite plates is to set reinforcing reinforcing bars in a formwork, inject cement mortar for the solid layer into the bottom plate side of the formwork, and pour the cement mortar for the solid layer onto the surface of the unhardened cement mortar for the solid layer. A manufacturing method has been proposed in which a mortar slurry for a lightweight layer is successively cast toward the upper part.

出来なかった。(Problem to be solved by the present invention) This is because the injection port for the mortar slurry for the light layer is generally not fixed, so the cement mortar for the dense layer is poured into a part of the cement mortar. High pressure is applied locally to the part of the surface of the cement mortar layer that serves as the inlet for the mortar slurry for the lightweight layer, resulting in deep fraying or inversion of the two layers, making it impossible to obtain a homogeneous composite plate. There wasn't.

。That is, the present invention prevents the cement mortar for the dense layer from cracking by injecting the mortar slurry for the light layer while spreading it in a layer on the surface of the unhardened cement mortar for the dense layer that has been poured into the formwork. This is a method of manufacturing a multilayer panel that does not cause the two layers to be reversed. Note that the term "layered" as used herein means that the mortar slurry for the light layer flows slowly over the sheet and spreads over the surface of the dense layer, and the pouring speed is preferably 0.27 to 0.54 M'' per minute.

It is preferable to set it within a range of 0.7. Note that it is preferable to set the injection auxiliary jig 3 in advance in the formwork or place it on the reinforcing reinforcing bars 6 as described above. In addition, the injection auxiliary jig 3 contains mortar slurry for the light layer at 10 to 5
It can also be removed after it has been cast to a thickness of about 0%. The polyethylene sheet 4 preferably has a size approximately equal to the area of the bottom plate of the form.
