MULTILAYER CONSTRUCTION PANEL AND METHOD OF ITS MANUFACTURING Russian patent published in 2012 - IPC E04C2/26 

FIELD: construction.

SUBSTANCE: multilayer construction panel comprises a heat insulation material and a reinforcing element of a steel sheet perforated according to a type of thermal profile. The heat insulation material is formed from natural raw materials or raw materials returned into a cycle in the form of cellulose fibres and/or agglomerated vegetable wastes. The reinforcing element is arranged inside the heat insulation material layer along the width and the length of the panel and is arranged as corrugate with arrangement of corrugations along and across or at the angle to the length of the panel. The method for manufacturing of the panel includes preparation of natural raw materials or raw materials returned in the cycle in the form of cellulose fibres and/or agglomerated vegetable wastes, preparation and homogenisation of the mass, preliminary moulding of the homogenised mass, arriving from a batcher, by means of its supply for preliminary moulding on a continuous moulding tape for paper making, serially serving to retain and dehydrate the mass during preliminary moulding, introduction of the pre-moulded panel for drying into a tunnel furnace. Preliminary moulding of the homogenised mass is carried out in two stages. At the first stage onto the pre-moulded homogenised mass a reinforcing element is laid from a steel sheet perforated according to a type of heat profile, on which then the second stage of pre-moulding of the homogenised mass is carried out.

EFFECT: invention makes it possible to increase strength and rigidly of a construction panel.
