Space-planning solutions

The reconstructed school building was built in 1961 according to the standard design of the architect S. AND. Evdokimov of the Khrushchev period. The existing building is 3 - 4-storey U-shaped in plan with a basement and a technical underground. Structural scheme - load-bearing longitudinal and transverse brick walls and, in part, monolithic reinforced concrete columns. In general, the existing building has the I degree of fire resistance and the class of constructive fire hazard C0. The project provides for the reconstruction of the existing school building with a built-in preschool educational institution (on the first and second floors of the east wing) with the addition of new gym buildings and a two-bowl swimming pool (for younger students and for middle and older students). For preschool educational institutions, two new staircases of the 1st type are organized in the volume of the building and two external evacuation stairs of the 3rd type on the facade. The project provides for the preservation of the historical corridor layout of the school building with one-sided placement of classrooms and classrooms. In the basement and part of the technical underground, it is planned to lower the existing floor to accommodate dressing rooms of grades 5-11, pantries of the catering unit and technical rooms (ventilation chambers, water metering and heating units, cable room). In the school part of the building on the ground floor there are primary classes with a wardrobe, a dining room with a kitchen, a medical unit, staff offices and technical rooms. On the second floor there are also primary classes, an assembly hall, a hall for outdoor games and staff offices. On the 3rd-4th floors there are classrooms for grades 5-11, a library, an Indian dance class and an Indian living room. On the ground floor of the preschool educational institution there are two group cells, a catering unit, a laundry room and a medical unit with a separate exit to the street. On the second floor there are also two group cells, halls for music and physical education, and staff quarters. The main entrance to the preschool educational institution is supposed to be from the yard. The attached buildings of the gym and swimming pool for schoolchildren are designed in structures that also provide the I degree of fire resistance and the class of constructive fire hazard C0. The structural scheme is a monolithic reinforced concrete frame with monolithic ceilings and a coating. The new buildings are connected to the main walkway at the 3rd floor level. Technical rooms are located in the basement floors. On the ground floor there are changing rooms with showers and toilets for schoolchildren and a coach, and inventory rooms. On the second floor of the gym building there is a locker room block for outdoor games. In the interior decoration, it is supposed to use standard materials that have the appropriate fire and hygiene certificates. Floors in lobbies, corridors, recreation areas - ceramic granite, in wet and technical rooms - ceramic tiles, in classrooms, staff offices, bedrooms and playrooms - homogeneous linoleum, in the gym - special sports flooring. Walls in classrooms, offices, corridors, recreations, bedrooms and playrooms - plaster with subsequent painting, in wet rooms - ceramic tiles, in technical rooms - finishing for painting and painting with PVA.  Exterior decoration of the walls of the building. The cladding of the plinth, the walls of the porches and, in part, the pilasters is gray-brown porcelain stoneware. Walls from the first to the fourth floor - polymer plaster (main field - RAL, pilasters - white). Filling of window openings - two-chamber double-glazed windows in metal-plastic bindings of white color. Canopies over the entrances to the building are supposed to be made of cellular polycarbonate on a metal frame. Improvement of the territory. The project provides for a fire paved passage around the building with exits to Mechnikov Ave. In the northern part of the territory there is a sports zone with a football field, a running track, a jumping sector, a combined basketball and volleyball court and a playground for outdoor activities. In the western part of the territory, two parking lots for 7 cars each are planned. In the eastern part of the territory there is a container platform and, isolated from the school zone, walking areas for preschool educational institutions.

 Constructive decisions

 Due to the fact that this building is in terms of a building with dimensions of 60,0x21,0 m, consisting of different-storey (1 ... 3 floors) parts, while being in different temperature and humidity conditions, the project provides for its division into - shrink blocks. At the same time, this division is made based on the symmetry of the building in the plan, as well as the functional and space-planning features of the building and includes three blocks separated by expansion joints between the axes "6.1"/"6.2" and "13.1"/"13.2". The maximum length of the temperature-shrinkable block is 30,0 m in axes. To ensure junction with the foundation of an existing building, settlement joints are provided between the axes "T" / "T.2" and "U" / "U.1", separating the building structures from the transition structures and the existing building. The structural scheme of the building is adopted in the form of an incomplete monolithic reinforced concrete frame with frames and additional stiffening diaphragms in the places of stairwells. At the same time, in order to unify and simplify the production of formwork, the frame columns are taken to be of the same section (40x40 cm), the width of the crossbars is taken to be constant and equal to the width of the columns. The rigidity of building blocks is ensured: in the vertical plane by the presence of frames and walls fixed in the foundation; in the horizontal plane by the presence of monolithic floor disks, rigidly connected to the frames and walls and transferring vertical and horizontal loads to them. As part of the project, two options for covering the building section above the bath room with a span of 9,6 m were considered: installation of a monolithic beam ceiling with a beam span of 9,6 m; pavement of prefabricated reinforced concrete multi-hollow prestressed slabs 400 mm high manufactured by OAO Barrikada. At the same time, despite the simplifications that arise during the installation of prefabricated reinforced concrete roof slabs, the option with the installation of a monolithic beam roof was adopted as a design option as it ensures the reliability of the structures used, incl. in case of improper use of the building.

 Foundations

 The foundations are designed on a natural basis. Due to the fact that this building is adjacent to the existing foundation of the school, sedimentary joints are arranged at the transition points, which make it possible to even out the deformations of adjacent parts of buildings with different pressure on the ground and to connect to the existing foundation at the level of its bottom mark. In order to ensure uniform settlement of the building and its parts, made of different number of storeys and with different spacing of adjoining elements, the foundations for the building are designed in the form of a monolithic reinforced concrete slab. The basis of the foundations is EGE-2. To ensure the rigidity of the foundation and in order to reduce the volume of work on backfilling the basement floor, the project adopted a monolithic reinforced concrete slab of concrete class B25F50W4 400 mm thick directly under the building (Fm1 foundation) and combined pairwise freestanding foundations for the transition structures (Fm2 foundations). Due to the high level of groundwater, the side surfaces are subject to mandatory waterproofing. Drainage is adopted as a waterproofing, in combination with surface treatment with hot bitumen of the preparation top and side surfaces to the level of the planning relief, which provides high protection against groundwater in sandy and sandy loamy soils. Reinforcing outlets under the basement walls and columns of the same diameter, which are used to reinforce these structures, are provided from the foundation slabs. To ensure the anchoring of the reinforcement, it is bent into the foundation slab. Reinforcing outlets are provided for the amount of the required overlap with a mandatory separation of the rods along the length. The working reinforcement of wall and column protrusions is adopted from class AIII reinforcement. Foundation concrete class B25F50W4. To prevent the leakage of cement laitance from the foundation during concreting and to improve the quality of concrete work under the foundation, preparation is carried out from concrete of class B7,5 with a height of 100 mm. The layout of the foundations and the main sections and details on them are presented on sheet KZh-2.

 basement walls

 The basement walls are made up to the level of floors with a thickness of 200 mm from monolithic reinforced concrete of class B25F50W4. The working reinforcement of the basement walls is installed vertically and is designed for two loading cases: as a statically indeterminate beam with pinching at the level of the top of the foundation and hinged at the level of the junction of the ceiling under pressure from the ground (for the case of backfilling before the installation of overlying stone walls); a beam of a similar design, taking into account the longitudinal load from the overlying stone walls. Concreting of the basement walls is carried out simultaneously with the concreting of the frame columns to ensure joint work when transferring horizontal loads. The layout of the basement walls and details on them are presented on sheet KZh-3.

 Pool bowls and overflow tank

 Pool bowls and overflow capacity are made of monolithic reinforced concrete. The thickness of the walls and the bottom of the baths is assumed to be 200 mm (with a maximum size of the bottom plate of 3,1x3,0 m and a hydrostatic maximum water level of 1,25 m). Slopes are provided along the bottom of the pools in accordance with the technological and architectural requirements. Reinforcement of the walls and bottom of the pool bowls is carried out with separate rods of class AIII reinforcement. Concrete of pool bowls and overflow tank class B25F50W10. Based on the fact that the dimensions of the pool bowls are 12,0 x 6,0 m in plan, the project does not provide for the separation of the structures of the pool bowls from the frame structures. In this case, the lateral pressure from the hydrostatic water pressure is perceived by the frame structures. To ensure trouble-free operation of the overflow tank, the latter is separated from the foundation plate structure by means of an independent bottom device. The load-bearing structures of the pool bowls are a system of load-bearing beams and columns. In this case, the columns are taken with a section of 30x30 cm, beams with a width of 30 cm and a variable height along the slope (the minimum height of the crossbar is 40 cm). Concrete of beams of class B15F50W10, concrete of columns of class B15F50W4. The layouts of the bowls of the pools and the overflow tank, as well as the sections for them, are presented on sheets KZh-6 and KZh-2, respectively.

 The walls of the stairwells

On the outer sides of the staircases, monolithic reinforced concrete walls with a thickness of 200 mm are made of heavy concrete of class B25F50W4. Reinforcement of the walls is carried out with separate rods of class AIII reinforcement. Concreting of walls is carried out one floor high.

 Frame columns

As mentioned above, the frame columns are assumed to be of the same section with dimensions in the plan of 40x40 cm. The reinforcement of the columns is carried out in accordance with the calculation as eccentrically compressed elements with 4 reinforcing bars with class AIII reinforcement with a section according to the calculation. The transverse reinforcement is adopted by Ф6AI with a pitch of 400 mm, and in the support zones and in the places of bypassing of the rods - 200 mm. The protective layer is taken at least 30 mm, which provides the necessary degree of fire resistance of building structures. Reinforcement of columns is carried out with separate rods with reinforcement bypass at the level of interfloor ceilings. In this case, the reinforcing bars are set apart. Concrete of columns grade B25F75W4.

 Frame crossbars

 Frame crossbars are of 2 types: with spans of 6,9 m or less - 40x40 cm high (including the thickness of the adjacent slab); with spans of 9,6 m, height 70x40 cm (including the thickness of the adjoining slab). Reinforcement of crossbars is performed in the upper and lower zones as continuous beams, taking into account the necessary anchoring of the reinforcement. Working fittings of class AIII crossbars. Transverse reinforcement of crossbars of class AI, installed with a variable step along the length of the span. The protective layer of crossbars is adopted at least 30 mm, which provides the necessary fire resistance of building structures. Beam concrete class B25F50W4 (concrete class B25F100W4 is used for transition columns).

 Overlap

 The ceilings are made of monolithic reinforced concrete with a thickness of 200 mm. The increased thickness of the slabs is associated with the device of an incomplete frame frame, in which the slabs work as bare-bones in places where there are no crossbars. Reinforcement of floors is carried out in the upper and lower zones as continuous structures, taking into account the necessary anchoring of the reinforcement. Working fittings of class AIII crossbars. The protective layer of reinforcement is adopted along the bottom of the plates at least 20 mm, which provides the necessary fire resistance of building structures. Ceiling concrete class B25F50W4.
