Structural solutions (residential building).

The structural scheme of a residential building is designed from prefabricated reinforced concrete load-bearing panels of longitudinal and transverse walls and floor panels "per room" with hinged 3-layer panels of external walls. The building has two expansion joints for the entire height of the building, designed in the design of the "corner" insert. Spatial rigidity is ensured by the joint work of the transverse and longitudinal internal walls, floor disks and the reliability of the platform joint. Enclosing structures (external walls) - prefabricated reinforced concrete panels of class B15 concrete, 350 mm thick with reinforcement of classes A-III, VR-I, with insulation with polystyrene foam PSB-S grade 15A, 150 mm thick. Internal walls - single-layer reinforced concrete panels with a thickness of 260,220,180 and 140mm, with fittings of classes A-I, A-III, VR-I. The class of concrete of the internal wall panels is accepted from the technical underground up to the 4th floor inclusive - B30, above the indicated floors - the class of concrete B22,5. Rigidity diaphragms - prefabricated reinforced concrete wall panels, 260,220,180mm thick. Ceilings - precast concrete panels "per room" thickness 140mm; Covering - prefabricated reinforced concrete panels of class B15 concrete, 260-340 mm thick with a slope, with reinforcement of classes A-III, VR-I, with insulation with polystyrene foam PSB-S grade 25A, 100 mm thick, pasted over with PVC film 150 microns thick. Landings - prefabricated reinforced concrete; Flights of stairs - prefabricated reinforced concrete; Bay windows - the device of bay windows is formed by a floor-by-floor increase in the length of the bearing internal transverse walls. Balconies, loggias - prefabricated reinforced concrete; The attic is warm; Gutter - internal; Elevator shafts - prefabricated reinforced concrete bulk; Roof - 3-layer waterproof rolled carpet; Partitions - prefabricated reinforced concrete, 80mm thick. The foundations of the building are a monolithic reinforced concrete slab 800 mm thick made of B22,5 class concrete; W6, normalized composition for concrete preparation with a thickness of 100mm. from concrete B7.5 on a natural basis, reinforced by the method "Geocomposite" according to the project. External walls - prefabricated reinforced concrete panels of class B22,5 concrete, 250 mm thick, with reinforcement of classes A-I, A-III, VR-I. with insulation with polystyrene foam PSB-S grade 15A, thickness 100-150mm. The inner walls of the underground part of the building are prefabricated reinforced concrete panels of class B30 concrete, 220 mm thick, with reinforcement of classes A-I, A-III, VR-I.. The panels have openings for the passage of service personnel and for laying communications. All structures in contact with the ground are coated with hot bituminous mastic for 2 times. To maintain the technical underground in a dry state, a wall ring drainage device is provided. Waterproofing of underground structures - from a cement-sand mortar 1: 2, painting.

Structural and technical solutions of the above-ground part of the building (Extension KP2). 

Enclosing structures: (outer walls of the above-ground part of the building) - enclosing three-layer: the outer layer is a hinged facade system with an air gap, fixed to the supporting structures of the building according to the RONSON NVF system with stainless steel fasteners. middle layer - rigid mineral wool slabs VENTI BATTS Dtm with a dense top layer that acts as a windproof film 150 mm thick - inner layer - brickwork of solid brick 250 mm thick (outer walls of the above-ground part of the building within the sports hall) - enclosing: outer layer - hinged facade a system with an air gap, fixed to the supporting structures of the building according to the NVF "RONSON" system with stainless steel fasteners. the middle layer is hinged sandwich panels for the entire height of the walls, fixed to the supporting metal structures. Sandwich panels are insulated with 150 mm thick KAVITI BATTM rigid mineral wool boards - the inner layer is solid brick masonry to a height of ~ 3300 mm from the top of the ceiling. Frame: columns with a section of 400x400mm, pylons with a thickness of 300mm - monolithic reinforced concrete made of B25 concrete, reinforced with A500C class reinforcement. In the sports hall in the outer walls, metal I-beam columns are used, untied in height and at the top level with metal I-beams and girders. The internal walls are monolithic reinforced concrete, 200 mm thick, made of B25 concrete, reinforced with A500C class reinforcement. Stiffness diaphragms are monolithic reinforced concrete walls of all stairwells and metal ties in the construction of the sports hall Ceilings are beamless monolithic reinforced concrete 220 mm thick made of B25 concrete, reinforced with A500C class reinforcement. The coating is a monolithic reinforced concrete slab 220 mm thick made of B25 concrete, reinforced with reinforcement class A500C. Above the sports hall, the covering is made of profiled flooring on metal beams, insulated with rigid mineral wool RUFF BATTS slabs and a monolithic reinforced concrete base made of B25 concrete; Jumpers monolithic reinforced concrete; Landings and marches are monolithic reinforced concrete made of B25 concrete, reinforced with A500C class fittings; Prefabricated and monolithic reinforced concrete steps made of B25 concrete, reinforced with A500C class fittings; Drain internal organized; The walls of the elevator shafts are monolithic reinforced concrete made of B25 concrete, reinforced with A500C class fittings; Roof: - vapor barrier-roofing material; demolition-expanded clay; insulation rigid mineral wool boards RUFF BATS, thickness - 200mm; polyethylene film, screed - cement-sand solution; coating -filizol - 3 layers. Partitions brick and plasterboard. Structural and technical solutions for the underground part of the building. The foundations of the building are monolithic reinforced concrete made of B25, W8 class concrete on a natural base reinforced by the Geocomposite method: for walls - tape, 1200 mm wide, 400 mm thick; -for columns - free-standing with banquettes, size 3000x3000mm, thickness 700mm; Reinforcement of foundations with class A500C reinforcement; Under the foundations, a concrete preparation 100 mm thick made of B10 concrete is arranged. Strip foundations for the supporting structures of the attached premises are moved 1500 mm from the foundation slab of the 25th floor. a residential building to exclude the influence of reinforced soils made under it; The outer walls of the underground part of the building are monolithic reinforced concrete 300 mm thick made of concrete of class B25, W8; reinforced with class A500C fittings. The walls are insulated with extruded Penoplex 35, 100 mm thick and protected by a pressure wall made of solid bricks. Backfill the sinuses with sand; The inner walls of the underground part of the building are monolithic reinforced concrete with a thickness of 200, 300 mm from concrete of class B25, W8; reinforcement with class A500C fittings; The foundations for the floors of the underground part of the building are monolithic reinforced concrete, 200 mm thick, made of B25 class concrete, reinforced with A500C class reinforcement, supported by walls and columns.
