Description
Basic data for the proektirovaniyanominalny sizes of a plate in the plan − ln x bn = 4000 h1500 mm. Skins made of FSSF grade V/V plywood according to GOST 3916.1. Longitudinal ribs made of spruce boards of 2nd grade; transverse - 3rd grade according to GOST 8486-86. Glue based on resorcinol and melamine with preliminary mixing of components. Insulation - mineral wool slabs on synthetic binder grade 75 with a thickness of 160 mm with sound= 75 kg/m3 according to GOST 9573-96 (thickness is determined by heat engineering calculation). Insulation - coating bitumen. To prevent atmospheric humidification of panels during transportation and storage, 1 layer of perhamine must be pasted on the top skin of the panel. Roll roof type K-1 as per SP 17.13330.2017 from bitumen-polymer roofing material. Structural solution: 1st layer - "Technoelast KhPP" 3.0 mm thick. It is carried out by free laying of the roll material, with its mechanical attachment, since the fire method of sticking with a burnt base under the water insulation carpet is unacceptable 2-th layer - "Technoelast KhPP" with a thickness of 3.0 mm. Glued by the smelting method of the bitumen-polymer layer.3-th layer - protective, "Technoelast TKP shale" with a thickness of 4.2 mm. It is glued by the smelting method of the bitumen-polymer layer.

Calculation of glued insulated coating slab with plywood cladding
Design Input
Nominal plan dimensions of the plate - ln x bn = 4000 x 1500 mm.
FSSF grade V/V plywood cladding as per GOST 3916.1.
Longitudinal ribs of spruce boards of the 2nd grade; transverse - 3rd grade according to GOST 848686.
Resorcinol and melamine based adhesive with preliminary mixing of components.
Insulation - mineral wool slabs on synthetic binder of grade 75 160 mm thick with sound= 75 kg/m3 according to GOST 957396 (thickness is determined by heat engineering calculation).
Vapour insulation - stain bitumen.
To prevent atmospheric humidification of panels during transportation and storage, 1 layer of perhamine must be pasted on the top skin of the panel.
Roll roof type K-1 as per SP 17.13330.2017 from bituminous polymer roofing material. Constructive solution:
The 1st layer − "Tehnoelast HPP" 3.0 mm thick. It is carried out by free laying of roll material, with its mechanical attachment, since the fire method of sticking when the base is burned under the water insulation carpet is unacceptable.
The 2nd layer is "Technoelast KhPP" 3.0 mm thick. It is glued by the smelting method of the bituminopolymer layer.
3rd layer - protective, "Technoelast TAP shale" 4.2 mm thick. It is glued by the smelting method of the bituminopolymer layer.
