The outer walls of the gas station buildings are designed from three-layer metal "sandwich panels" on a metal frame. Roofing - rolled, with a base of three-layer metal roofing "sandwich panels" on metal structures, with internal drainage. The entrance to the building for visitors is designed along a ramp. Glazed doors - with anti-shock film class A3. The canopy is a “T”-shaped structure in plan with overall dimensions of 16,280 x 7,500 m and 27,000 x 9,000 m, height to the top of building structures h = 5,8 m. The structure is designed in a metal frame with building structures sheathed with aluminum composite panels . Roofing - from steel profiled flooring on metal structures. Drainage from the roof of the canopy is organized through downpipes passing through the lining of the columns. The project provides for unimpeded access for people with disabilities and people with limited mobility to the gas station building.

Structural and space-planning solutions

The gas station project provides for the construction of a gas station building, a canopy over the gas station islands with a transition to the gas station building, as well as 3 underground fuel tanks located under the gas station islands. The gas station building is designed as one-story, rectangular in plan, with dimensions in the axes of 14,56 x 9,56 m. The height of the building is assumed to be 4,38 m from the planning level to the top of the parapet. The canopy over the fuel dispensers with the transition to the gas station building is assumed to be T-shaped in terms of size (27,00 x 9,00) + (16,28 x 7,50) m and a height of 6,02 m from the planning level to the top of the parapet. Tanks for fuel are adopted underground steel double-walled capacity of 50 m3, each located under the fuel islands. The frame of the gas station building is designed according to a two-span structural scheme. Frame spacing in axes – (2,645 + 6,180 + 2,835 + 2,900) m. Frame spans in axes – (6,325 + 3,235) m. The columns on which the canopy rests over the passage to the gas station building are made of steel from square pipes measuring 140x6mm in accordance with GOST 30245-2003. The fastening of all columns to the foundation slab is provided rigid. The roof beams are designed from rolled steel I-beams according to STO ASChM 200-8 and channels according to GOST 30245-2003. Coating runs are made of rolled steel channels according to GOST 20-93. The roof beams are fastened to the columns and the girders to the beams are hinged. The covering of the gas station building is designed from three-layer sandwich panels over metal over steel girders. The fastening of the covering panels to the girders is provided by self-tapping screws. The spatial rigidity and stability of the gas station building are provided by the rigidity of the columns fixed in the foundations, as well as by vertical and horizontal connections. 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 11.1 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 W6 for water resistance and F150 for frost resistance, 150 mm thick with longitudinal and transverse ribs 650 mm high to support the frame racks. For a relative mark of 0,000, the mark of the clean floor of the building of the operator gas station was taken, corresponding to the absolute mark of +14,900 m in the Baltic system of heights. The canopy over the fuel dispensers with 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 the steel portals of the fuel tanks, welded to the embedded parts of the foundation slabs. The basis of the canopy frame are two double-span frames with spans of 9,0 m each with cantilever outlets of crossbars 4,44 m long and a distance between frames of 2,5 m. The canopy frame columns above the fuel dispensers are made of steel from square pipes measuring 250 x 8 mm in accordance with GOST 30245-2003, on which the coating of I-beams is pivotally supported according to STO ASChM 20-93, and runs from steel rolled channels in accordance with GOST 8240-97 , united by galvanized steel profiled sheets H75-750-0,8 in accordance with 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 control room building. The calculation of the load-bearing structures of the canopy was performed using the SCAD 11.1 design and computer complex without taking into account the joint action of the “structure-foundation-foundation” system. The foundations for the portals of the fuel tanks are designed in the form of monolithic reinforced concrete slabs made of concrete of class B20 in terms of strength, grades W6 in terms of water resistance and F50 in terms of frost resistance. Under the foundation slabs, preparation of medium-sized sand is provided. The base of the sand cushion under the foundation slab of the gas station operator building is light silty, soft plastic, layered, brown loam with the following characteristics (EGE1): ρII=1,96g/cm3, e=0,742, IL=0,61, φII=18°, sII =21kPa, E=9,5MPa. The average pressure under the sole of the foundation slab of the control room building is p=0,95 kgf/cm2. Estimated soil resistance of the base under the sand cushion of the foundation slab of the control room building R=3,47kgf/cm2. Expected average design settlement of the foundation slab of the gas station building S=2,0 cm.

The basis of the foundation slabs of the portals of fuel tanks is dusty, plastic, with gravel and pebbles, gray sandy loam with the following characteristics (IGE2): ρII=2,18g/cm3, e=0,409, IL=0,10, φII=30°, cII= 22kPa, E=14,0MPa. Estimated soil resistance of the base under the foundations of the canopy R = 4,63 kgf / cm2. The average pressure under the base of the canopy foundations is p=1,83 kgf/cm2. The expected average design settlement of the canopy foundations is S = 2,8 cm. To protect underground structures from the aggressive effects of groundwater, the project provides for the use of concrete grade W6 for water resistance.
