Method and device for the production of a lightweight building board and lightweight building board

摘要

A fresh concrete core layer is generated by applying fresh concrete to a continually moving first sub-layer. Outer layers (3a,3b) are generated on a continually moving second sub-layer. The prefabricated outer layers are applied to the core layer. A skein of layers is cut into single boards, which can then be joined to timber-work. The boards are dried as required. An independent claim is also included for a device for producing a multilayer light building board on a cement base with a core layer and outer layers on the main surface of the core layer.
