General information.

The total area of ​​the shelter, according to the results of measurement work, is 888,8 square meters. m. The dimensions of the building in the axes are 90,0x36,0 m, the height of the premises is 3,53 m. 3. The level of the finished floor of the 0,000st floor of the building is taken as the 1 mark. 4. Shelter class (shelter group) - A-II. The shelter is built into a building that meets fire resistance class II, confirmed by inspection results. The main design solutions for the overhaul facility: external walls of the shelter made of prefabricated reinforced concrete. panels 400 mm thick; frame made of monolithic reinforced concrete. columns, crossbars, stiffening diaphragms; monolithic reinforced concrete ceiling; reinforced brick partitions with a thickness of 250 and 120 mm. Anti-corrosion protection of metal floor beams, fecal tanks, metal elements is carried out with the Barrier-zinc composition according to TU 2312-001-16406613-2013. Restoration of the protective layer of reinforcement with the composition "Skrepa 500 Repair". Treatment of enclosing surfaces and floors with penetrating waterproofing
"Penetron". Sound insulation of the partitions of the ventilation chamber and diesel power plant rooms bordering the room for those being sheltered is carried out with Acoustic-Butts material in Knauf frame cladding and covered with chipboard (with flammability class G 1) 12 mm thick. Insulation of external walls with sprayed urethane foam (G 1) after treatment with penetrating waterproofing Penetron. A layer of urethane foam with a density of 50 kg/m3 should be 50 mm thick, according to thermal engineering calculations. For insulation, perform cladding C 623 according to series 1.073.9-2.08, issue. 1 with chipboard lining (flammability class G 1) 12 mm thick (at the Customer’s request).
