From the second floor there are two emergency exits leading to the internal and external stairs. Doors of evacuation exits open in the direction of movement during evacuation. Stained-glass window in the stairwell is fireproof type 1. The exit to the roof is designed by an external steel ladder. Doors in the premises of an individual heating point, a heating chamber, office equipment, as well as from the tire fitting and car wash rooms to the corridor of the 1st floor in the axes "3-5" are fire-resistant manufactured by the PULSE company with a fire resistance limit of EI 30.

Constructive decisions

The building of the car wash is two-storey with dimensions in the axes 18,0x24, Ohm. The building is designed as a frame type. Bearing columns are made of rolled I-beams 25K1 (STO ASChM 20-93). The foundations for the columns are monolithic reinforced concrete columnar. Foundation materials: concrete class B25, grades W6, F75 (GOST 26633-91*), reinforcement class A-III and AI according to GOST 5781-82*. Along the perimeter of the building, monolithic reinforced concrete foundation beams are provided for the brick basement of the building. Floor slabs and coatings at el. +3,500 and +6,900 - monolithic reinforced concrete with corrugated sheet formwork on metal beams from I-beams 30Sh1, 25Sh1 and 25B1 (STO ASCHM 20-93). The total thickness of the slab is 150mm, concrete class B25. The material of metal structures is steel of class C255 according to GOST 27772-88*. The base of the foundations is brown-brick loam, hard-plastic, with interlayers of silty sand, incl. up to 10% pebbles, gravel. The design resistance of the soil is assumed to be R = 3,0 kg/cm2. The maximum pressure on the sole R= 1,13kg/cm2. The maximum settlement of a columnar foundation is 5,2 cm, with a maximum allowable of 12,0 cm. The external enclosing structures of the building are designed from sandwich panels manufactured by MetallProfil, 120 mm thick. Internal partitions are made of foam concrete blocks, 100 mm thick. The roof is without attic, with an external organized drain. The roof has parapets with a height of at least 600 mm. The roof structure was developed on a monolithic reinforced concrete slab with a thickness of 150 mm on a profiled sheet. The designed building is designed: III degree of fire resistance and constructive fire hazard class CO in accordance with SP 118.13330.2012. Fire resistance limit of building structures: columns - R45; ceilings, beams, girders, etc. - REI 45; external non-bearing walls - E15. The fire resistance limit in reinforced concrete building structures is provided by a protective layer (in ceilings - 25 mm); in steel structures coated with fire-retardant intumescent paint "TERMA LUX".
