Architectural and space-planning solutions

 The project documentation provides for the construction of a stationary filling station with an operator building and a canopy over fuel dispensers. The building of the control room and the canopy over the fuel dispensers are the components of the filling station designed for refueling cars and trucks, as well as servicing drivers and passengers. The control room building is a one-story frame building without a basement or an attic, rectangular in plan, with dimensions in the extreme axes of 19,06 x 9,86 m. The greatest height of the vertical plane of the facade from the planning ground level (-0,310 m) to the top of the parapet is 4,61 m. The height of the premises to the bottom of the suspended ceilings is 3,0 m, 2,50 m. The mark of the clean floor of the building is taken as a relative mark of 0,000. The building houses: a trading floor with an operator's area, a station manager's room, a collection room, a staff room with a dressing room, a shower room, a dining room, a water meter unit, a storage room for cleaning equipment, a technician's room, a pantry for food products, a pantry for non-food products, an electrical panel room, a vestibule, corridors , sanitary facilities. The main entrance to the building is designed from the side of the main facade. The main facade of the building is oriented towards the territory of the station. The stained-glass window occupies the main area of ​​the main facade. The frame is metal. Walls - sandwich panels 150 mm thick with mineral wool filling. Partitions - from plasterboard sheets (GKL, GKLV, GKLO) on a metal frame with mineral wool filling, 98 mm and 125 mm thick. Stained-glass window, stained glass doors and windows - made of anodized aluminum profiles with double-glazed windows with A2 protective film. Window blocks - made of anodized aluminum profiles with double-glazed windows with A2 protective film. Doors - metal, metal-plastic and wooden, in accordance with GOST and individual production, in the usual and fire-resistant design. The roof is flat, combined, insulated, with a roof made of rolled materials (the top layer is with gravel protection) on a profiled steel sheet along girders and beams. Drainage - external organized. Door blocks, bindings, frames, plums and fittings are white. The interior decoration of the premises and the floors were designed in accordance with the purpose of the premises and the recommendations of the Corporate Style Book of the consumer brand of the gas station chain: floors - with floor tiles; internal lining of external wall panels - from GKL, GKLV, GKLO, followed by painting with water-based paint, facing with ceramic tiles or wallpapering; suspended ceilings made of acoustic tiles and sheets of GKL and GKLV and slatted. Premises with permanent residence of people are designed with natural light. A canopy is designed above the fuel dispensers and above the space between the control room building and the fuel dispensers. The canopy over the fuel dispensers is a modular-frame structure, the rectangular projection of which has a plan size of 27,00 x 13,45 m. The highest height from the planning ground level (-0,310 m) to the top of the roof is 6,110 m. The connecting canopy between the control room building and the fuel dispensing islands is a frame-type structure, the rectangular projection of which has a plan size of 14,14x10,00 m. The frame is metal. The roof is flat, with corrugated steel sheet roofing over girders and beams. The drain is internal. Covering the area under the canopy - concrete sparkling and oil and petrol resistant tiles. The finishing material is a smooth metal sheet with a polymer coating. Measures are envisaged to ensure the accessibility of the building and facilities for people with limited mobility. The main entrance-exit to the building is equipped with a ramp. The ramp has a width of 1,20 m, the slope is within 8%, the surface is hard, non-slip. Doorways do not have thresholds. The width of the door panels is assumed to be at least 0,9 m.

Structural and space-planning solutions

 The control room and shed buildings are designed in a steel frame. Level of responsibility – II. The constructive scheme of the control room building is a complete frame. The node supporting the roof beams on the columns is hinged. The spatial immutability of the frame of the control room is ensured by the joint work of the columns, rigidly fixed in the foundation, and the hard disk of the cover. The rigidity of the coating disc is ensured by fastening the corrugated board to the girders in each wave on the extreme spans and through the wave on the middle spans. The sections of the main load-bearing structures of the frame were adopted: columns - square pipes according to GOST 30245-2003 from steel C255; roof beams - I-beam according to STO ASCHM 20-93 from steel C245, roof decking - H75-750-0.8 according to GOST 24045-94. As external enclosing walls, hinged wall panels of the “sandwich” type 150 mm thick are used; A fachwerk system has been developed for fixing wall panels. The foundation for the control room building is a non-buried monolithic reinforced concrete slab 180 mm thick, with monolithic beams along the contour and under columns 500 mm high, made of B20, W4, F50 class concrete. To prevent freezing of the base of the foundation slab, insulation is provided with plates of extruded polystyrene foam. A cushion of coarse-grained sand is arranged under the foundation slab. In accordance with the report on engineering and geological surveys, the base is the EGE-2 layer (light silty loam, with gravel and pebbles), which has the following characteristics: ρн=2,15 t/m3; e=0,492; n =23о; Сn=0,35 kg/cm2; E=120 kg/cm2. The average pressure under the sole of the foundation slab is 1,94 kg/cm2. The design soil resistance of the base is 2,53 kg/cm2. The expected settlement of the foundation slab is 0,3 cm. The spatial invariability of the canopy frame is ensured by the joint work of the columns, rigidly fixed in the foundation, and the hard disk of the profiled flooring, which is fastened with self-tapping screws in each wave. The node for supporting the main beams of the roof on the columns is hinged. Columns - I-beams according to STO ASChM 20-93 from steel C245, canopy beams are designed from I-beams according to STO ASChM 20-93 from steel C245, corrugated board - H75-750-0.8 according to GOST 24045-94. The foundations for the canopy columns are monolithic reinforced concrete columnar foundations made of concrete of class B20, W4, F150. In accordance with the report on engineering and geological surveys, the base is the EGE-2 layer (light silty loam, with gravel and pebbles). The average pressure under the base of the foundation is 1,05 kg/cm2, the design soil resistance of the base is 2,45 kg/cm2. Expected draft - 1,7 cm, horizontal movement - 4,35 mm. The foundations of underground reservoirs are taken on a natural basis in the form of a monolithic reinforced concrete slab 400 mm thick, concrete class B20, W4, F50. The basis for the foundations for the tanks is the EGE-2 layer (light silty loam, with gravel and pebbles). The design of the foundations provides stability against ascent. The project provides for coating waterproofing of the outer faces of the foundations in contact with the ground. The calculation of the main load-bearing structures was performed using the SCAD software package version R11.3. The displacements and deflections obtained as a result of the spatial calculation of the building frame do not exceed the maximum allowable values. The relative mark of 0,000 corresponds to the absolute mark of 56.41. During the period of the survey, groundwater was not encountered at the site. The maximum level of groundwater is expected during periods of snowmelt and heavy rainfall is expected on the surface of the earth, at absolute levels of 55.35-58.70.
