Structural and space-planning solutions

The control room, washing and shed buildings are designed in a steel frame. Level of responsibility – II. The spatial immutability of the frame of the control room is ensured by the joint operation of the columns, which have a rigid junction with the foundation slab, and a pavement disk with ties in the longitudinal and transverse directions. The spatial immutability of the sink frame is ensured by the joint operation of the columns, which have a rigid junction with the foundation slab, and the cover disk. The node for supporting the roof beams on the columns is designed as a hinged one. The sections of the main load-bearing structures of the frame were adopted: columns - round pipes according to GOST 8732-78 from steel C20, bent closed square sections according to GOST 30245-2003 from steel C255; covering beams - I-beam according to STO ASChM 20-93 from steel C245. Hinged wall panels of the “Sandwich” type with a thickness of 150 mm are used as external enclosing walls. A fachwerk system has been developed for fixing wall panels. The roof of the building is made of sandwich type roofing panels 200 mm thick. The foundations for the control room and washing buildings are non-buried monolithic reinforced concrete slabs 250 mm and 200 mm thick, respectively, with monolithic beams along the contour and under columns 500 mm and 660 mm thick. Under the foundations, bulk soil is sampled, followed by the installation of an artificial foundation. Foundation material - concrete B20 and B25, W6, F150. To prevent freezing of the foundation slabs, insulation with foam slabs is provided. The spatial invariability of the canopy frame is ensured by the joint operation of the columns, which have a rigid support unit on the foundation, and a hard disk of the profiled flooring, which is fastened with self-tapping screws in each wave. The roof beams are hinged on the columns. The sections of the main load-bearing structures of the canopy frame were adopted: columns - round seamless pipes according to GOST 8732-78 from steel C20; the main roof beams are wide-shelf I-beams according to STO ASCHM 20-93 from steel C255; corrugated board - H57-750-0.7. The foundation for the canopy columns is monolithic reinforced concrete columnar concrete B20, W6, F75. In accordance with the report on engineering and geological surveys, the base of the canopy foundation is the EGE-2 layer - heavy loams, with the following characteristics: ρn=1,94 t/m3, Cn=0,21 kg/cm2, E=100 kg/cm2. The design soil resistance of the EGE-2 base is R = 17,6 t/m3. The foundations of underground reservoirs are taken on a natural basis in the form of a monolithic reinforced concrete slab 300 mm thick, concrete B20, W6, F150. The basis for the foundations for the reservoirs is the IGE-3 layer - light silty loam with the characteristics ρн=2.02t/m3, Сн=0.18kg/cm2, Е=90kg/cm2. The design of the foundations ensures the stability of the foundations against ascent. All foundations are arranged according to concrete preparation from B7.5 concrete. 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 of the frames was carried out using the SCAD software package. The displacements and deflections obtained as a result of the spatial calculation of the building frame do not exceed the allowable values. The expected settlements of buildings and structures do not exceed the allowable ones.
