Architectural solutions

Architectural and planning solution

In accordance with the functional purpose of the designed multi-storey garage-parking lot for placing cars (cars) of extra small, small and medium classes, a five-story building with 2 stairwells on the southwestern facade and one staircase of the 3rd type on the southeastern facade. The building includes: basement (elev.-1.650); 1st floor (elev. 0.000, +1.500) - 36 parking spaces (30 of which are for people with limited mobility), two boxes: a box for one car and a box for two cars; four typical floors with 61 parking spaces on each floor, respectively, 4 parking spaces on 244 floors. The parking garage has two entrances and two exits. Car passages on the floors are designed taking into account the possibility to correct the direction of car movement at any time without the need to leave the floor. To move cars in the parking garage building, the project provides for two double-track ramps. Heated premises are also located on the 1st floor: a rest room, a security room, rooms for washing equipment and primary fire extinguishing equipment, an electrical panel room, a water meter unit, a pump room, bathrooms for staff and visitors, a corridor. To provide access to the building at elevation 0.000 and elevation +1.500 for people with limited mobility, ramps with a slope of 1:12 are provided. Volumetric-spatial solutions. The volumetric solution of the building of a multi-storey garage-parking lot is dictated by the shape of the plot leased for construction. In general, the parking building has a rectangular shape. The main facade of the parking lot is designed asymmetrically. As a finishing of the main plane of the facade of the parking lot - colored plaster, the color of the facades - warm light colors.

Structural and space-planning solutions

The section of the project was developed on the basis of the following documents: Architectural and planning task; Conclusions on the IGI of the design and construction site; Agreed specifications for building design. building category. The level of responsibility of the car park building is II (according to STO36554501-014-2008). The degree of fire resistance is the second (according to SNiP 31-01-2003). Loads and impacts. Permanent and long-term loads - according to the geometric dimensions of structural elements and volumetric weights of materials. Temporary normative: for floors - 500 kg / m²; stairs - 300 kg / m². Soil pressure on the basement wall - 1300 kg / m²; Normative wind load - II region - 30 kg / m²; Estimated snow load - III district - 180 kg / m²; Structural scheme of the building and materials used. The building is a frame system with a longitudinal column spacing of 7,5 m and a transverse spacing of 5,5 m and 7,5 m. Floor slabs rest on beams. The rigidity of the building is ensured by the setting of transverse and longitudinal load-bearing walls. Structural system - column according to SP52-103-2007. The plan size of the parking garage is 60,83 x 37 m. The building has two staircases with monolithic walls. An evacuation metal staircase is provided at the end of the building. From horizontal movements, the stairs are attached to the ceilings of the building. Communication between floors is carried out by ramps. There are also ramps for the disabled. Ramps for the disabled, stairs with elevation -1,700 and foundations of metal stairs are carried out separately from the main structure of the building. The expansion joint divides the parking garage into two sections. Columns - monolithic reinforced concrete (dimensions 400x800 mm, concrete B25, W6, F150). External walls of the basement of the parking lot - monolithic reinforced concrete (thickness 400 mm, concrete B25, W6, F150). The inner walls of the parking lot are monolithic reinforced concrete (thickness 200 mm, concrete B25, W6, F150). Ramps, ceilings and covering of the car park are monolithic reinforced concrete (220 mm thick, concrete B25, W6, F150). Beams - monolithic reinforced concrete (dimensions 400x400 mm, concrete B25, W6, F150). Stairs - walls and monolithic reinforced concrete platforms (thickness 200 mm, concrete B25, W6, F150), marches - prefabricated reinforced concrete according to the catalog of marches of JSC "Metrobeton" 04-LM, based on platforms. The spatial rigidity and stability of the parking garage is ensured by the joint work of the transverse and longitudinal load-bearing walls of the parking lot and the hard disks of the floors. Calculations of the load-bearing structures of the designed parking lot were carried out using the StructureCAD 11.3 software package. Foundations. The foundations of the building are piled according to the series 1.011.1-10 v.1 of piles 350x350, 15 m and 16 m long. Concrete class grillages B900, W25, F6. Under the grillages, the project provides for the implementation of concrete preparation with a thickness of 150 mm, made of concrete of class B 100. The basement floor is designed on the ground. The relative elevation of 7.5 for the parking building corresponds to an absolute elevation of +0.000. According to the IGI report, at the base of the foundations there are silty sandy loams, with gravel and pebbles, with lenses and nests of sand, gray, hard, chosen as the base layer of the pile tips. The piles are sunk into the support layer by at least 5,250 m. The design load on the pile is assumed to be 2 tons based on the results of the calculation according to SP150-50-102 and the results of the static test. Under the foundations, a sand cushion is provided (medium-grained sand with layer-by-layer compaction), compaction coefficient kcom = 2003. On the leveled surface of the sand cushion, concrete preparation was made, 0,96 mm thick, from concrete of class B100. In case of performance of work at negative temperatures, do not allow freezing of the base soil. Given the weak soils lying near the surface, it is necessary to lay geotextiles before backfilling with medium-grained sand. The maximum value of the groundwater level is expected during the period of snowmelt, intense precipitation at a depth of 7,5-0,5 m, the average annual position of the level is at a depth of about 1,0 m. According to its composition, groundwater has a weak degree of aggression in relation to normal concrete waterproof W2,0. Protection of underground structures from the impact of groundwater. To protect the underground structures of the car park from the aggressive effects of groundwater, this project provides for the use of concrete with increased water resistance of class B6, W25, F6. To protect underground rooms and foundations from capillary moisture, waterproofing is provided - 150 layers of isoplast on hot bituminous mastic over the underlying concrete layer with an overlap of 2 m on the walls. Fire protection. In accordance with the requirements of STO 36554501-006-2006, the degree of fire resistance of structures is provided for: Walls and piers - REI 90; Overlappings of the building - REI 45; Flights of stairs - R 60. The main results of the calculation. Deflection of the top of the building under construction (section 1) 2,99 mm. Deflection of the top of the building under construction (section 1) 0,67 mm. Geotechnical monitoring. The project provides for instrumental monitoring of settlements and deformations of the structures of the building under construction for the period of construction and operation of the designed parking lot until the stabilization of the settlement. Technical solutions and drawings 08-10-1/1 KR are presented in full in volume 4 (Album No. 1).
