Architectural and space-planning solutions

The polyclinic building for 600 visits per shift with the emergency department is rectangular in plan, with protruding staircase volumes, with a total size in the axes of 57,0 x 39,0 (m), has a basement floor, 3 above-ground floors, an upper technical floor. The maximum height of the building from the planning ground level to the top of the parapet is 16,15 m. The basement floor, 2,57 m high, provides for the placement of wardrobes for the staff of the polyclinic with sanitary facilities, technical rooms designed to accommodate engineering equipment. On the ground floor, the following are designed: a vestibule group of premises, clinical diagnostic laboratories, a group of premises for infectious disease doctors, an emergency department with an isolated entrance, and auxiliary premises. The second floor provides for the placement of therapeutic, surgical and X-ray departments, a sterilization department, a conference room, a complex of premises for a therapeutic pool. The pool hall is a two-height space with natural light through skylights in the roof above the hall. The third floor provides for the placement of the department of functional diagnostics, the department of physiotherapy and exercise therapy, service and administrative premises. Above the third floor, in axes 1-7 and 12-18, the project provides for a technical floor 2,90 m high, designed to accommodate ventilation equipment. The height of the above-ground floors is 3,60 m. For vertical connection between the floors, there are four stairwells with access to the street, one internal staircase from the 1st to the 3rd floor, a cargo-passenger elevator designed to transport fire departments and evacuate MGN and a hospital elevator. For access to the premises of the basement, there are isolated entrances from the street and a technological staircase leading to the level of the first floor, which has a vestibule-lock with air overpressure in the basement. The roof is flat, with an internal organized drain. Filling of window openings - metal-plastic window and stained-glass blocks from a temperature-controlled profile with filling with double-glazed windows. Facade finishing: a basement, walls of above-ground floors - porcelain stoneware facade tiles on a metal frame attached to the monolithic frame of the building, and a layer of insulation from facade mineral wool boards; volumes of staircases and, in part, facades - facade mineral wool slabs attached to the outer walls, plastered and painted with facade paints. Partitions - from aerated concrete blocks, in rooms with a wet regime and technical rooms - brick. Interior decoration is carried out in accordance with the functional purpose of the premises from materials that have hygienic and fire certificates. The project provides for measures to ensure conditions for the life of people with limited mobility: an external open ramp for lifting to the level of the first floor, elevators for lifting visitors on stretchers and in wheelchairs, fire-safe zones on the floors, bathrooms for the disabled.

Structural and space-planning solutions

Building responsibility level – II (normal). The building was designed according to the combined structural scheme. The basement floor was designed according to an incomplete frame scheme, with external load-bearing walls. The upper floors - according to the frame-wall design scheme, with a frameless frame. The outer walls of the basement are monolithic 400 mm thick with foam insulation and with a pressure brick wall 120 mm thick. The internal walls of the basement are monolithic, 200 mm thick. The material of load-bearing underground structures is monolithic reinforced concrete, concrete class B25, F75, W6, reinforcement class A400, A240. The frame columns are designed according to the grid 6,0 x 6,0 (m) and 4,5 x 6,0 (m). Frame columns - with a section of 400 x 400 (mm), columns under the pool bowl - with a section of 300 x 300 (mm), entrance group columns - with a diameter of 350 mm. The outer walls of the stairwells are monolithic, 400 mm thick, the inner walls are monolithic, 200 mm thick. Interfloor floors and roofing - monolithic reinforced concrete beamless continuous slabs 200 mm thick. The coating provides for the installation of monolithic reinforced concrete beams for fastening structures of lanterns above the pool, developed by a specialized organization. The structures of the stairs are monolithic reinforced concrete. The material of load-bearing ground structures is monolithic reinforced concrete, concrete class B25, F75, reinforcement class A400, A240. The structures of the pool bowl are designed from monolithic reinforced concrete of class B25, W6, the thickness of the walls and bottom is 300 mm. The load from the pool is transferred through the columns to the foundation slab. External walls - non-bearing, with floor-by-floor support on ceilings, multilayer, made of aerated concrete blocks of class B1,5, F35 400 mm thick, mineral wool insulation 80 mm thick and a ventilated facade system with porcelain stoneware cladding. The connection of the layers and the fastening of the walls to the supporting frame is carried out by flexible connections with an anti-corrosion coating. Structural solutions for fastening the ventilated facade system to the supporting structures of the building are developed in the working documentation in accordance with the current technical certificate of the Ministry of Regional Development of the Russian Federation. The spatial rigidity and stability of the building is ensured by the joint work of columns and stiffening diaphragms, united by hard disks of floors. The calculation of load-bearing structures was performed using the Stark ES 2010 program, taking into account the joint work of the building with the foundation. A relative elevation of 0,000 corresponds to an absolute elevation 17.57 m. The foundations of the building are a monolithic reinforced concrete slab made of concrete of class B25, F75, W6, 600 mm thick, on a cushion of medium-grained sand with layer-by-layer compaction 2,0 m thick. grain size, dense, saturated with water with φ=4º, e=39kg/cm0,03, E=2 kg/cm450 and IGE2a - sands of medium size, medium density, saturated with water with φ=4º, e=36kg/cm0,02, E=2 kg/cm350. The expected draft does not exceed 2 cm. The normative depth of soil freezing is 1,46 m. ​​To prevent freezing, the basement walls are insulated. The designed building is located in the existing building, at a distance of 12,5÷25 m from the transformer substation, residential buildings and the building of the children's clinic.
