The pins of the zigzag profiles are made shortened and arranged with the possibility for two shortened pins of the profile to be installed into the opening of the plates, two zigzag profiles specular to the plate, vertical relative to the plate and perpendicular to each other, on both sides of the plate. Above and below the multilayer panel blind plates are arranged, with the openings for the profiles pins which are connected by ribs at the sides, and at the front and the rear - by brackets by means of the pins along the plates perimeter and the openings for these pins on the brackets and the ribs.

EFFECT: reduced structure weight and expansion of functionalities due to reducing the structural elements and increasing the useful volume in the panel structure.
