Architectural solutions.

The building of a general education school for 33 classes (825 students) with two swimming pools 25x11m and 10x6m for year-round use was designed in accordance with the design assignment
The building is 4-storey, with a basement. The height of the main floors from floor to floor - 3,9m, basement - 3.0m, technical underground - 1.8m. The number of storeys of the building is due to the tightness of the site. The degree of fire resistance of the building is II. Building responsibility level – II. The constructive fire hazard class of the building is C0. Functional fire hazard class - F 4.1. Fire hazard class of building structures - K 0. The building has a complex configuration in plan, divided in the middle part into two fire compartments by a firewall. One compartment is a 4-storey extended volume of an educational group of premises: with classrooms, laboratories, classrooms, recreation, circle rooms and workshops, a library center. The second compartment is a conditionally square 2-3-4-storey volume with a school-wide group of premises: administrative premises, gyms, swimming pools, an assembly hall, a catering unit and related premises. Pool halls, gyms and an assembly hall are “double-height” premises. For a relative mark of 0,000, the floor level of the 1st floor was taken, corresponding to the absolute height mark of 10.12. The total height of the building from ground level is 20.910 m. The maximum dimensions in the plan are 117,8 x 96,1 m. Technical and economic indicators:

Volumetric-spatial solution

The volume-spatial solution of the school building was developed in accordance with the design assignment. The building is symmetrical about one axis. A clear internal structure - division into two groups of premises - educational and general school - dictates a clear three-dimensional solution: two large volumes of the building, connected, as it were, by a hall hinge with an elevator node located in it. The central position of the elevators is convenient, functionally accessible to all rooms. The main entrance to the school building is located along the axis of the extended volume of the educational building, which has a smooth concavity. The architectural design creates a rhythmic buildup towards the center. The interior of the educational building, despite its length (about 117 meters), due to the bend, does not give the impression of an endless corridor. The system of light recreations allows you to create comfort for the rest of each of the steps of students. The initial I level of education, which includes grades 1-4, has a separate entrance with its own vestibule and its own dressing room and is located on floors 1-2 to the left of the main entrance; Stage II (from 5 to 9 grades) and Stage III (grades 10-11) occupy the 3rd and 4th floors of the educational building. Classrooms of the II level are allocated in a separate compartment impassable for other levels. A group of training workshops is located on the first floor to the right of the main entrance. The complex of the library and club rooms is located in the central part of the educational building on the 4th floor. The volume of the general school part is formed by a dining hall, an auditorium, two sports halls - large and small, two halls of a large and small pools, compactly located along the axis of symmetry. Each of the elements of the school's infrastructure is provided with all the necessary set of auxiliary and production facilities.

Exterior finishing of facades

The color scheme of the facades used: face brick of 2 colors - “creamy smooth” and “brown smooth” for walls, manufacturer - Pobeda LSR group of companies, artificial stone for plinth cladding - "Viennese Clinker" of the "Ideal Stone" group of companies. The plasticity of the facades is created using decorative elements - wall planes of different colors, stained glass design of the entrance group, stairs, recreations. The main entrances to the school building are stained glass.

Interior finish

The interior finish was appointed in accordance with the recommendations of the technologist and the requirements of SNiP 2.08.02-89 * "Public buildings", SanPiN 2.4.2.1178-02 "Hygiene of children and adolescents. Institutions of general secondary education", SanPiN 2.2.1/2.1.1.1278-03 "Hygienic requirements for natural, artificial and combined lighting of residential and public buildings", SanPiN 2.4.5.2409-08 "Sanitary and epidemiological requirements for catering for students in educational institutions , institutions of primary and secondary vocational education”.

Structural and space-planning solutions.

The object being designed is a 4-storey brick building of an educational school for 825 students with a complex configuration. Estimated outdoor air temperature of the coldest day - minus 30ºС, the coldest five-day period - minus 26ºС; Humidity zone – humid; According to the snow load, the construction belongs to the III district. The calculated value of the weight of the snow cover is 180 kg / m². According to the wind load, the construction belongs to the II region. Speed ​​normative wind pressure - 30 kg/m². The structural basis of the building is a bonded monolithic frame without crossbars with vertical stiffening diaphragms. In the longitudinal and transverse directions, the spatial rigidity and stability of the building is ensured by the joint work of a monolithic reinforced concrete floor, monolithic reinforced concrete columns and monolithic reinforced concrete diaphragms. Additional cores of rigidity are stairwells and an elevator shaft made of monolithic reinforced concrete.

• Ceiling over the basement - 0,44t/m²;
• Ceiling over technical premises - 0,64t/m²;
• Typical overlap - 0,57t/m²;

The calculated value of the load on the stage is 1,32t/m²; on balconies - 0,62t/m²; The roof is made of a combined flat on a monolithic reinforced concrete slab of thicknesses. 250mm, in the area of ​​sports and assembly halls - on a prefabricated reinforced concrete multi-hollow prestressed slab of bench formless molding of thicknesses, 500mm (made of B40 W4 F100 concrete, reinforced with prestressed reinforcement - K7 ø12 ropes according to GOST 13840-68, manufactured according to TU 5842- 052-03984346-2003)
