Structural and space-planning solutions

Building responsibility level – II. The 1-2-3-story preschool building was designed in a bracing frame of the 1.022 KL-2 series from standard prefabricated prefabricated reinforced concrete elements. Columns - prefabricated reinforced concrete with a section of 4040cm. Crossbars - prefabricated reinforced concrete, tee section, 45 cm high, 6,0 m span and 60 cm high, 7,2 m and 9,0 m span. Stiffness diaphragms - prefabricated reinforced concrete 140 mm thick. Ceilings and roofing - from prefabricated reinforced concrete bonded solid slabs and ordinary hollow flooring 220 mm thick. Overlap above the pool area - flat slabs-spacers 220 mm thick. The outer walls of the basement are designed from monolithic reinforced concrete (concrete B20, W6, F100) 260 mm thick with an outer layer of insulation. External walls - self-supporting single-layer wall panels 120 mm thick with an outer layer of insulation 150 mm thick and finished according to the Bolix M system. Rigidity, stability and geometric immutability of the building are provided by rigid pinching of columns in the foundation, joint work of frames and stiffening diaphragms, hard disks of floors and roofing. The rigidity of the disk of floors and roofing is ensured by the installation of spacer plates along the axes of the columns, which have a welded connection with crossbars. Pools - a monolithic reinforced concrete bowl made of B25, W8 concrete (bottom thickness - 200 - 400 mm along beams with a section of 300500 (h) mm, wall thickness - 200 mm) on racks with a section of 300 × 300 mm. The project documentation provides for internal waterproofing of the pool bowl. Stairs - prefabricated reinforced concrete marches and platforms. Ventilation blocks - prefabricated reinforced concrete bulk molding. Partitions in the area of ​​stairwells walls of elevator shafts - brick, 250 mm thick. The relative mark of 0,000 corresponds to the absolute mark of +15,500. The load-bearing structures were calculated using the Lira 9.6 software package. The foundations are taken on a natural basis in the form of a monolithic reinforced concrete slab 500 mm thick made of concrete B20, W6, F100. Under the foundations, concrete preparation is provided with a thickness of 100 mm. The foundations are based on light silty, weathered, hard EGE-2 loams (e = 0.634, IL = -0.10, E = 170 kg/cm2). The expected draft of the building is 5,0 cm. In July 2011, specialists of the State Institution "Center for Expert and Technical Support" carried out a survey of the surrounding buildings: residential building No. 35, bldg. 3 on the street. Oleko Dundich and the buildings of the TP. Impact on the surrounding development is not expected, as the distance to the nearest building (16.85 m) exceeds the depth of the compressible layer (6,9 m).
