Architectural solutions.

The space-planning solution of the school building for 1100 places consists of two rectangular volumes 2 and 4 floors high, connected by a transition volume. The height of the building from ground level to the top of the parapet of the roof of the four-story wing of the building is 17,52 m. The height from ground level to the bottom of the window opening of the last floor of the four-story wing of the building is 13 m; three-story wing - 13,64; two-story wing - 1 m, the transition between them - 5,25 m. The number of storeys of the building: 2-4 floors. Number of floors: 3-5 floors. The height of the floors is assumed: 1st floor (from the floor to the false ceiling) - 3,3 m in the main rooms; 2,6 m in corridors, recreations; 3,0 - library, sanitary facilities, to the ceiling / to the bottom of the coating - 2,5 m (in engineering rooms). The height of the assembly hall to suspended ceilings is 5,3 m, the pool is 7,2 m, the sports halls are 7 m. The basement (from floor to ceiling) is 2,8 m. The height of the space for laying networks from floor to ceiling is 1,7, 1100 m. The architecture of the school is made in a modern style using the compositional and decorative techniques of the stylistics of the present. In accordance with the terms of reference, the building of primary and secondary education at XNUMX places are designed for the organizational and pedagogical structure - the class size is 25 students.

Constructive decisions.

The school being designed is a multi-storey (from two to four floors excluding basement) building, divided into seven blocks, including a transition, separated by a deformation and temperature-shrinkage joint for independent operation of building blocks. The blocks are designed on separate, independently operating foundations. The dimensions of the object in the axes are 103,95 x 226 m. The maximum size of the temperature-deformation block is 51,86 x 36,95 m. The relative ground floor elevation of 0.000 corresponds to the absolute +17,000. According to the constructive scheme, the building is a column-wall system. The connection between the columns and the foundation is rigid. Under the whole building there is a basement with a room height of 1,7 m and 2,85 m to the bottom of the ceiling. Steps of load-bearing structures are variable from 4,0 to 8,0 m. The height of the first floor is 4,06 m (between floors), the height of the remaining floors is 3,66 m, 3,76 m. The premises of the assembly, sports halls and the swimming pool hall are double-height. Coatings above them are steel trusses with a span of 22,01; 18,97; 16,6; 15,06; 13,1 m. The foundation is a monolithic reinforced concrete slab 500 mm thick with a base elevation of -2,640 and -3,790, concrete of class B25, W8, F150. Bearing monolithic reinforced concrete structures: - basement walls - monolithic, reinforced concrete outer walls 200 mm thick; internal walls 180 mm, concrete class B25, W6, F150, reinforcement class A500C and A240. - columns with a section of 500x500 mm; in the basement of concrete class B25, W6, F150, on the first floor and above B25, F75, reinforcement class A500C and A240. - floors - monolithic reinforced concrete slabs 240 mm thick with capitals over columns with a total thickness of 400 mm. A strapping beam is provided along the contour of the plates. Ceilings above the basement from concrete class B25, W6, F150. Ceilings above the 1st floor and above from concrete class B25, F75, reinforcement class A500C and A240. Coating boards B25, F75. The reinforcement of the slab is knitted, long rods are laid with an overlap of at least the required one. - landings - monolithic, reinforced concrete. - flights of stairs - prefabricated, reinforced concrete. - elevator shaft - monolithic, reinforced concrete, separated from the frame by an expansion joint. The building includes two swimming pools. A swimming pool with a water surface of 2x8 m is arranged in the axes Y-BB / 25-11. The pool bowl rests on the foundation slab through pylons 400 and 250 mm thick. The thickness of the walls of the pool is 400 mm, the bottom is 300 mm. A swimming pool with a water surface of 10x13 m is arranged in the axes Y-BB / 10-6. The pool bowl rests on the foundation slab through pylons 400 and 250 mm thick. The thickness of the walls of the pool is 400 mm, the bottom is 300 mm. Covering the building in the axes E-P / 3-7, Ya-VV / 2-7, 10-13 / AA-BB, 12-15 / U-Sh, Zh-M / 27-33 - a bar structure consisting of flat steel trusses supported by monolithic reinforced concrete columns. The spatial rigidity of the frame is provided by a system of vertical and horizontal ties connecting the truss belts. The trusses are supported at the level of the upper belt. Truss span 22,01; 18,97; 16,6; 15,06; 13,1 m. When calculating flat trusses, the joints in the nodes are assumed to be articulated, the application of loads is distributed and concentrated. Trusses are made without cuts, with belts and a lattice of bent-welded profiles of rectangular and square sections in accordance with GOST 30245-2003. The construction materials of the upper and lower truss chords, as well as the support braces - C345 according to GOST 27772-2015, the material of the braces - C255 according to GOST 27772-2015. The project provides for horizontal and vertical connections along the lower and upper chords of trusses, from bent-welded square sections in accordance with GOST 30245-2003. Construction materials - C255 according to GOST 27772-2015. The lower chord of the truss is assembled using a flange connection with prestressed high-strength bolts M30 40X "select" in accordance with GOST 32484.1-2013. High-strength nuts according to GOST 32484.3-2013, high-strength washers according to GOST 32484.5-2013. The assembly of the elements of the flange connection is carried out in conductors. Welding of the flange and the attached square pipe should be carried out mechanized, while the welding technology should ensure minimal welding deformations of the flanges. After welding, the outer surfaces of the flanges must be milled. The thickness of the flanges after milling must not be less than that specified in the KM or KMD drawings. All mounting fixtures and temporary fasteners after installation must be removed, and the places of their welding must be cleaned and primed. Nuts of permanent bolts after alignment of structures must be secured from self-unscrewing by setting locknuts. During installation, the final fixing of the main structures should be carried out after their careful alignment and straightening. For the period of work, all steel structures must be secured against buckling. Elements of a closed section must have sheet metal plugs 4 mm thick at the ends. Slots in these elements must be welded with continuous seams to prevent moisture from entering the element. All steel structures must be painted in accordance with the guidelines of SP 28.13330.2017. The quality of the paintwork must comply with class V according to GOST 9.032-74. The coating solution is a monolithic reinforced concrete slab 200 mm thick on profiled flooring grade H114-750-1,0. Factory connections - welded. Automatic or semi-automatic welding according to GOST 8713-79* or GOST 14771-76 with instrumental control methods. Mounting connections - on bolts. M16, M20 bolts of accuracy class B in accordance with GOST 7798-70*, strength class 5.8, 8.8 in accordance with GOST R ISO 898-1-2014 with factory brand and strength class marking. Holes for M16 ∅19mm bolts, for M20 ∅23mm bolts. Nuts for bolts M16, M20 accuracy class B according to GOST ISD 8673-2014 strength class 8. Flat washers are accepted according to GOST 11371-78*. The transverse and longitudinal stability and rigidity of the building are ensured by rigid pinching of the columns into the foundations, the presence of rigid monolithic disks of the floors, the presence of stiffening cores of the staircases. The rigidity of the joints is ensured by the required length of reinforcing bars. Horizontal loads are redistributed by floor disks between vertical columns clamped in the foundation in two directions. The load-bearing structural system of the building is designed in such a way that vertical load-bearing columns are located one above the other from the foundation along the entire height of the building. The calculation of the overall stability of the building and its movements, the determination of the existing loads on foundations, walls, ceilings and other structures was carried out using the Lira CAD 2021 program, which implements the calculation using the finite element method.
