METHOD TO DETERMINE STRUCTURAL PARAMETERS OF COMPOSITE WALL PANELS Russian patent published in 2015 - IPC E04C2/04 

FIELD: construction.

SUBSTANCE: invention relates to composite wall panels. The method to determine properties of paper lining of a wall board, including a stage, when they take the value of wall board core stiffness, a stage, when they determine the required value of resistance to pulling of nails, based on technical requirements to a wall board, and a stage, when they calculate the value of paper lining stiffness, based on the taken values of core stiffness and determined value of resistance to pulling of nails. The method includes a stage, when the calculated value of paper lining stiffness is displayed on a display device.

EFFECT: production of panels having required values of resistance to pulling of nails.
