Architectural and space-planning solutions

The project documentation provides for the construction of an IVECO car service station. The building is one-story, with a two-story insert, an attached spare parts warehouse, an attached compressor room and a built-in boiler room. The building is complex in plan, with dimensions in the extreme axes of 60,20x27,22 m. For a conditional mark of 0,000, the level of the finished floor of the first floor of the building is taken, which corresponds to an absolute mark of 29.25. The maximum height of the building from the planning level of the ground to the roof ridge is 7,93 m. In the building at the level of 0,000, the following are designed: a repair site, a warehouse for special tools, a warehouse for spare parts, a compressor room, a boiler room, a meeting room, and bathrooms. In the insert at the level +2,950, the following are designed: a rest room, an archive. The height of the repair area from the floor level to the bottom of the protruding structures - 5,70 m, the height of the warehouse - variable: 2,97 - 2,53 m, the height of the boiler room - 3,24 m, the height of the compressor room - variable: 3,00 - 2,50 m, the height of the premises of the first floor of the insert is 2,74 m, the height of the premises of the second floor of the insert is 2,24 m. For access to the second floor of the insert, an internal open metal staircase is designed. Access to the roof is provided by an external vertical metal ladder type P1. External walls - brick and sandwich panels. Coating - pitched combined, from galvanized steel profiled flooring with insulation. Roof - from the steel pro-thinned-out sheets. Drainage - external, organized. Glazing - tape, filling window openings - from a metal-plastic profile with double-glazed windows. Internal walls and partitions, depending on the purpose of the premises, are designed from hollow bricks, gypsum plasterboard and gypsum plasterboard on a metal frame, reinforced concrete. Interior decoration is carried out in accordance with the functional purpose of the premises. For MGN at this enterprise, accessibility to the administrative and amenity building is provided (there are no administrative premises in the designed service station). 

Structural and space-planning solutions

 The level of responsibility of the structure is II (normal). The structure consists of two parts separated by a deformation-sedimentary seam. Structural scheme - a complete braced frame made of steel structures. Repair area. The frame columns are designed with a step of 4,0x17,8 m from I-beams according to STO ASChM 20-93 from steel C245. The junction of the columns with the foundation is decided as rigid. The structure of the roof is made up of trapezoidal truss trusses. The truss pitch is 4,0, the span is 17,8. The spatial invariability of the pavement disc is ensured by fastening the profiled flooring to the trusses and the system of ties and braces along the lower and upper chords of the trusses. External enclosing walls - hinged, made of sandwich panels, 150 mm thick. The spatial rigidity and stability of the building frame is ensured by the joint work of the transverse frames, vertical connections between the columns and the hard disk of the coating. The spatial calculation of the building frame was carried out in the 8CAB 11.3 software package. The maximum horizontal movement of the top of the building is 7,8 mm, which does not exceed the maximum allowable values. The foundations for the frame columns are taken on a natural basis as free-standing columnar monolithic reinforced concrete from concrete of class B25, U16, P50. The foundations are arranged according to concrete preparation with a thickness of 100 mm from concrete of class B7.5. The maximum draft is 8.9 mm, the relative difference of the draft is 0,0022, which does not exceed the maximum allowable values. The design soil resistance of the base under the base of the foundation is 1,74 kg/cm2. In accordance with the report on engineering and geological surveys, the foundations are EGE-3 soils - silty sands, of medium density, with interlayers of sandy loam and EGE-XNUMX - plastic sandy loam. EGE-2 has the following characteristics: rp=2,0 t/m3; e=0.650; fp=30°; cn \u0,03d 2 kg / cm "; 3 80 E \uXNUMXd TXNUMX kg / cm. EGE-3 has the following characteristics: rp=2.1 t/m; e=0,534; fp=27°; cn=0,17 kg/cm2; E=100 kg/cm2. Attached warehouse of spare parts Frame columns are designed with a step of 4,0x4,4 m from closed square profiles in accordance with GOST 30245-2003 from steel C245. The junction of the columns with the foundation is decided as rigid. Beams - metal, pivotally supported on columns, from channels according to GOST 8240-89 from steel C245. The coating is designed from profiled flooring in accordance with GOST 24045-94, which is attached to the purlins in each corrugation and ensures the rigidity of the coating disk. External enclosing walls - hinged from a sandwich panels, 150 mm thick. The spatial rigidity and stability of the building frame is ensured by the joint work of columns, vertical ties and the covering disk. The spatial calculation of the building frame was carried out in the 8CAB 11.3 software package. The maximum horizontal movement of the top of the building is 8,2 mm, which does not exceed the maximum allowable values. The foundations are an unburied monolithic reinforced concrete slab 200 mm thick made of concrete of class B25, U^b, P50. The foundations are arranged according to concrete preparation with a thickness of 100 mm from concrete of class B7.5. Under the foundation slab, an artificial base is arranged instead of fully selected bulk soils. Estimated soil resistance of the base K = 2,32 kg / cm .
