Structural and space-planning solutions

The filling station project provides for the construction of a filling station building, a canopy over the filling stations and a transition to the filling station building, as well as 2 underground fuel tanks located under the filling islands. The filling station building is designed as one-story, rectangular in plan, with dimensions in the axes of 15,70 x 10,70 m. The height of the building is assumed to be 3,65 m from the planning level to the top of the cover. The canopy over the filling stations and the passage to the gas station building is assumed to be T-shaped in terms of size (18,50 x 8,00) + (9,33 x 8,00) m and a height of 5,70 m from the planning level to the top of the parapet. Tanks for fuel are taken underground steel double-walled with a capacity of 50 m3 each. The frame of the gas station building is designed according to a two-span structural scheme. Frame pitch in axes - (5,15 + 5,40 + 5,15) m. Frame spans in axes - (6,90 + 3,80) m. The frame columns are made of steel from square pipes with a size of 160x6mm in accordance with GOST 30245-2003. The columns on which the canopy rests over the passage to the gas station building are made of steel from square pipes measuring 200x8mm in accordance with GOST 30245-2003. The fastening of all columns to the foundations is provided rigid. The roof beams are designed from rolled steel I-beams according to STO ASChM 20-93 and channels according to GOST 8240-97. Coating purlins are taken from rolled steel channels according to GOST 8240-97. The roof beams are fastened to the columns and the girders to the beams are hinged. The coating of the gas station building is made of steel galvanized profiled sheets H75-750-0,8 in accordance with GOST 24045-94 for metal girders. The fastening of the corrugated sheets of the coating to the girders is provided by self-tapping screws on all supports in each wave. Between themselves, the sheets are fastened with combined rivets with a pitch of 300 mm. Spatial rigidity and stability of the gas station building are ensured by the rigidity of the columns fixed in the foundations, vertical ties and the rigidity of the coating disk. The outer walls of the gas station building are made of hinged insulated panels of the "Sandwich" type, fastened to the frame columns with self-tapping screws. The load-bearing structures of the gas station building were calculated using the SCAD 11.3 design and computer complex without taking into account the joint action of the “building-foundation-foundation” system. The foundation for the gas station building is designed in the form of a monolithic reinforced concrete slab on a natural base made of concrete of class B20 for strength, grades W4 for water resistance and F150 for frost resistance, 200 mm thick with longitudinal and transverse ribs 600 mm high to support the frame columns. Under the foundation slab of the gas station building, the project provides for the preparation of class B10 concrete with a thickness of 100 mm. For a relative mark of 0,000, the mark of the finished floor of the gas station building is taken, corresponding to the absolute mark of +12,700m in the Baltic system of heights. The canopy over the fuel dispensers and the transition to the gas station building is designed according to the frame structural scheme and is supported by the bases of the columns on metal portals, between which there are tanks with fuel. The basis of the canopy frame are two single-span frames with a span of 7,5 m with a distance between frames of 2,5 m with cantilever outlets of crossbars 3,5 m long. The canopy frame columns above the fuel dispensers are made of steel from square pipes of size 250x8 according to GOST 30245-2003, on which the coating of I-beams according to STO ASChM 20-93 and runs from steel rolled channels according to GOST 8240-97, combined with galvanized steel profiled sheets H75-750-0,8 according to GOST 24045-94. Fastening sheets of corrugated board to the purlins is provided by self-tapping screws in each wave. Between themselves, the sheets are fastened with combined rivets with a pitch of 300 mm. The spatial rigidity and stability of the canopy are provided by the rigidity of the columns fixed in the foundations, the hard disk of the roof, as well as the fastening of the roof beams to the columns of the gas station building. The calculation of the load-bearing structures of the canopy was performed using the SCAD 11.3 design and computer complex without taking into account the joint action of the “structure-foundation-foundation” system. Combined foundations for fuel tanks and portals for canopy columns are designed in the form of monolithic reinforced concrete slabs 400 mm thick made of concrete of class B20 for strength, grades W4 for water resistance and F100 for frost resistance. Under the foundation slabs of the tanks, the project provides for concrete preparation with a thickness of 100 mm. In accordance with the “Technical report on engineering and geological surveys for the construction project of gas stations ...”, the base of the sand cushion under the foundation slab of the gas station building is belt loam, heavy, silty, semi-solid, brown with rare gravel, with the following characteristics (EGE-2 ): ρII=2,01g/cm3, e=0,691, IL=0,24, φII=22°, cII=0,028MPa, E=12,0MPa. The bulk soils lying under the foundation slab of the gas station building and the canopy foundations are planned to be replaced by the project with a pillow with a thickness of at least 0,5 m of medium-sized sand, laid with layer-by-layer compaction. The maximum pressure under the sole of the foundation slab of the filling station building is p=8,2tf/m2. Estimated soil resistance of the base under the sand cushion of the foundation slab of the gas station building R = 10,0 tf / m2. The expected average design settlement of the foundation slab of the gas station building is S= 0,84cm. In accordance with the “Technical report on engineering and geological surveys for the construction project of gas stations ...”, the base of the foundation slabs of the fuel tanks and the canopy are layered, heavy, silty, hard-plastic, brownish-gray loams with rare gravel, with the following characteristics (EGE- 3): ρII=1,99g/cm3, e=0,700, IL=0,46, φII=21°, cII=0,023MPa, E=10,0MPa. Estimated soil resistance of the base under the foundation slabs of fuel tanks R=42,51tf/m2. The maximum pressure under the sole of the foundation slabs of the fuel tanks and the canopy is p=18,71tf/m2. The minimum pressure under the bottom of the foundation slabs of the fuel tanks and the canopy is p=10,27tf/m2. The expected average design settlement of the foundation slabs of the fuel tanks and the canopy is S= 0,73cm. The normative depth of seasonal freezing of the foundation soils is 1,49 m. For the period of field work, groundwater was opened at a depth of 0,7 m. In unfavorable periods of the year, the maximum level of groundwater is expected at the surface of the earth. Ground water is non-aggressive to all brands of concrete in terms of water resistance.
