Designed metal fire escapes for climbing to the roof and fire escapes on the height differences of the roof. Independent evacuation exits are designed from the basement floor. The building provides for the installation of a passenger elevator with a carrying capacity of 400 kg, two small cargo lifts with a carrying capacity of 100 kg and one platform lift. External walls - from the planning mark of the ground to the mark of 0,000 - monolithic reinforced concrete with foam insulation and subsequent finishing with porcelain stoneware on an adhesive solution. External walls from the mark of 0,000 to the mark of plus 3,970 m - brick with mineral wool insulation and subsequent finishing with porcelain stoneware according to the "ventilated facade" system. The outer walls above the mark plus 3,970 m are stained-glass windows and a system of hinged self-supporting "sandwich" panels finished with facade cassettes. Partitions - brick, from aerated concrete blocks, plasterboard (simple and moisture resistant) on a metal frame with mineral wool filling, tongue-and-groove. Windows and stained-glass windows - aluminum profiles filled with double-glazed windows. Doors - metal-plastic, metal and wooden, glazed and deaf, in fire-resistant and conventional design, custom-made and in accordance with GOSTs. Roof (covering) - combined insulated: above the multi-storey block - flat, above the block of pools - gable. Roofing - from rolled materials, separate operated areas - with a protective coating of paving slabs. The drain is internal. Exterior finish of the building - ceramic granite slabs, aluminum composite facing panels. Finishing of premises and floors - in accordance with the purpose of the premises: floors - granite, porcelain stoneware, concrete, ceramic tiles, TZI linoleum, lint-free carpet. The design of the floors in the halls of the pools is provided according to the "warm floors" system; walls - ceramic, polymer or glass tiles, plaster, water-based paint; ceilings - water-based paint; suspended and false ceilings - slatted, aluminum and "Armstrong" type. Measures are provided to ensure the accessibility of the building for the disabled and people with limited mobility: the dimensions of the entrance vestibule are taken to be at least 1,50 m deep and at least 2,20 m wide; width of corridors - not less than 1,60 m; floor covering - from materials that do not allow slipping; elevators are designed in the vestibule area and on the bypass path of the health-improving pool; width of door and open openings - not less than 0,9 m.

Structural and space-planning solutions

Building responsibility level – II (normal). The building was designed according to the frame structural scheme, divided by an expansion joint into 2 blocks. The columns are monolithic reinforced concrete. Variable column spacing (maximum spacing 6,0 x 9,6 m, spacing in the pool area 30,0 x 3,3 ÷ 6,0 m), column cross section 400 x 400 and 300 x 300 mm (at basement level), concrete B25. The outer walls of the basement are designed from monolithic reinforced concrete 250 mm thick with effective external insulation. Concrete B25, W8, F100. The outer walls of the building at the level of the first floor and in the pool area are self-supporting, consisting of solid bricks M150, F25 250 mm thick on a mortar M75 and the AluWALL ventilated facade system. The overlying outer walls are hinged sandwich panels 150 mm thick finished with facade cassettes. Connection of layers in the outer walls and fastening to the load-bearing structures of the building are provided by flexible connections with anti-corrosion coating. The ceiling above the basement is a monolithic reinforced concrete beamless 210 mm thick and partially along beams with a section of 1000 x 500 (H) mm. Concrete B25, W8, F100. Ceilings and roofing - monolithic reinforced concrete 180 mm thick along beams with a section of 400 x 450 (H) mm and from precast reinforced concrete slabs with a maximum span of 9,6 m, 400 mm thick, in the area of ​​\uXNUMXb\uXNUMXbrooms with wet and wet conditions - from prefabricated ribbed reinforced concrete slabs. Concrete B25. Covering over the pool - steel trusses with a span of 30 m with a step of 3,3÷6,0 m, designed from closed bent-welded profiles, on which runs from closed bent-welded profiles and bent channels (1,5 and 3 m step) and profiled flooring H75 are laid . Horizontal stiffness ties at the level of the upper chord of trusses and vertical stiffness ties from the truss plane - from closed bent-welded profiles. Steel C345 and C255. Vertical braces of frame rigidity are made of closed bent-welded profiles. Stairs - prefabricated reinforced concrete steps on metal stringers. Partitions - from aerated concrete blocks, in rooms with a damp and wet regime - from tongue-and-groove hydrophobized slabs. The bowls of the pools are made of monolithic reinforced concrete. Walls of the big pool - variable thickness from 350 to 200 mm. Walls of small pools - 200 mm thick. Bottom plates of small pools - 210 mm thick supported by columns. The bottom slab of the large pool is made of monolithic reinforced concrete with a thickness of 300 mm. Concrete B25, W8, F100, working reinforcement A-500s. The spatial rigidity and stability of the building is ensured by the joint work of pinched columns, vertical braces and floor hard disks. The calculation of load-bearing structures was carried out on a computer using the SCAD Office program and in an analytical way using the main regulatory documents. The relative mark of 0,000 corresponds to the absolute mark of 7.40. The foundations of the building are piled. Piles - prefabricated reinforced concrete, driven, section 35 x 35 cm, length 9,0 - 11,0 m. Concrete B25, W8, F75. The allowable design load on the pile is 60 tf, based on the results of static sounding. Prior to mass pile driving, the bearing capacity of the piles will be checked by static tests. Design solutions provide for control tests of four piles. Columnar grillages made of monolithic reinforced concrete 400 - 600 mm high, united by a slab 250 mm thick, concrete class B25, W8, F100.
