Structural and space-planning solutions

The level of responsibility of the structure is II (normal). Structural schemes of the enclosure and car wash buildings are an incomplete frame. Buildings are designed without basements. The internal columns of the frame are designed with a section of 380x510 mm from a solid brick of the M250 grade on a cement-sand mortar of the M150 grade. The spacing of the columns is 6,0 m. The internal load-bearing walls of the frame are made of brick, 380 mm thick, made of bricks of the M150 grade on a cement-sand mortar of the M150 grade. The supporting structures of the frame are reinforced with masonry mesh through 4 rows of masonry. Crossbars of the frame of the open-air cage are made of prefabricated reinforced concrete 6,1 m with a section of 40x40 cm according to the 1.125KL-3 series from concrete of class B25. The crossbars of the sink frame are made of metal I-beams according to GOST 26020-83 from steel C235. External enclosing walls - load-bearing brick 380 mm thick, made of M150 brick on cement-sand mortar M150 with pilasters to support frame crossbars with a section of 380x510 mm. The ceiling of the enclosure building and the covering are designed from prefabricated reinforced concrete slabs according to series 1.141.1 KL-3 from B25 class concrete. Prefabricated reinforced concrete slabs rest on crossbars and load-bearing brick walls. The rigidity of the floor and cover disks is provided by anchors that are welded to the embedded slabs and by sealing the joints between the slabs. The coating of the washing building is designed as monolithic reinforced concrete, 120 mm thick, class B25 concrete. The spatial immutability and stability of buildings is ensured by the joint work of the frame columns, transverse load-bearing walls and disks of floors and roofs. The staircase in the building of the enclosure is designed from prefabricated reinforced concrete steps on metal stringers from rolled channels in accordance with GOST 8240-97. The spatial calculation of the enclosure building was performed using the SCAD software package version 11.5.1. The maximum horizontal movement of the top of the building is 1,03 mm, the maximum settlement of the pile foundation is 6,5 mm, which does not exceed the maximum allowable values. The required fire resistance of reinforced concrete load-bearing structures is provided by increased protective layers of concrete for the working reinforcement of the structures. The foundations are designed with piles. Bored piles with a diameter of 300 mm and a length of 17,6 m were designed. The material of the piles is concrete B20, W10, F300. The design load on the pile is assumed to be 27,7 tons, which is confirmed by the data of static sounding of soils. The connection of piles with grillage is rigid. The grillage is a monolithic reinforced concrete tape with a height of 500 mm from concrete of class B20, W10, F300. The grillage is arranged on gravel preparation with a thickness of 100 mm with bitumen pouring over a sand cushion. The project provides for control testing of piles before the mass construction of the pile field. The relative mark of 0.000 corresponds to the absolute mark of 7.20. In accordance with the report on engineering and geological surveys, the basis of the pile foundation is the EGE-8 soil - gray silty sandy loam with gravel and pebbles, which has the following characteristics: Il=0,34; e=0,561; cn=0,15 kg/cm2; n=15о; E=120 kg/cm2.
