Architectural and planning solution.

The volume-spatial solution is determined by the town-planning situation, in which the design site is located, and the architectural environment that has developed at the present time. The projected building borders on ordinary buildings of the Soviet period. The U-shaped building is designed as a 2-section, 9-storey building. (code 10300 according to city plan) The absolute mark from the day surface to the cornice is -28 m, to the ridge - 33 m, which meets the requirements of the PZZ for this site. The last 9th floor is made in the form of an attic, in the constructions of an inclined semicircular roof. The main focus of the volumetric and spatial solution is the corner rounded part of the building with highlighted vertical glazed bay windows for living rooms and kitchens, combined at the level of the cornice and completed in the form of a glazed segment of the dome. The building is raised on a small stylobate, lined with granite, which is the operated roof of the parking lot. The ground floor also has rusticated natural stone cladding. As an exterior finish, decorative plaster with stone chips in 2 colors is offered. Inclined metal roofs, gables on three main facades, horizontal cornices, window framing made of vertical three-dimensional rods, the presence of light metal balcony railings - all these elements are characteristic of historical buildings. At the same time, glass and aluminum inserts in the corner bay windows of living rooms, partial glazing of balconies and loggias from the side of the courtyard, glazed dome design give lightness and a modern look to the projected building. According to the Customer's instructions, the building belongs to the "comfort" class. The apartment layout corresponds to the design assignment, the bulk of the apartments are 1 and 2-room apartments. All apartments have access to balconies or loggias, the planning solution of each apartment includes functional zoning and the possibility of combining living rooms with kitchens. Office premises are designed on the 1st floor (the code of the main types of use according to the urban plan is 12020). Each room has 2 emergency exits. On the instructions of the Customer, the offices are designed with an open layout with the allocation of bathroom zones. The building is of the II degree of fire resistance, the main supporting structures are a monolithic reinforced concrete frame and monolithic reinforced concrete. 200 mm thick walls (REI 45) and beamless slabs (REI 60). IN in the basement there is a parking lot for 66 cars (in the case of a 2-level arrangement of cars) or for 53 cars in the case of a traditional arrangement of cars. The parking lot is designed as an independent fire compartment, separated from the premises of the 1st floor by a monolithic reinforced concrete. overlay REI 60. It is possible to enter the parking lot from both sections through the main stair-lift halls through the vestibule locks with air overpressure at the parking level. Stairs are separated from the premises of the 1st floor by brick partitions 120 mm (REI 45). The decoration of the courtyard space is the parking lights, the designs of which are designed in the form of flower beds, and at night they are bright light elements. The stair-lift halls are equipped with a passenger-and-freight elevator with a carrying capacity of 630 kg with the possibility of transporting a stretcher and moving a disabled person in a wheelchair, and a garbage chute with the organization of garbage collection from the garbage collection chambers “from wheels”. The stair-lift halls are separated from the apartments by floor corridors. Entrances to residential sections and offices are equipped with ramps. Ffoundations: slab 500 mm on grillages on a pile foundation. Bearing walls: monolithic reinforced concrete. 200 mm thick walls from floors 2 to 9. On the 1st floor and in the basement: monolithic reinforced concrete frame and monolithic reinforced concrete walls 200 mm. Ceilings - beamless, monolithic reinforced concrete. 230 mm thick (between the basement and 1st floor) and 200 mm (on the overlying floors Exterior finish: 1st floor - facing with natural stone (or porcelain stoneware), above 1st floor - mesh plaster. External walls - partial filling with bricks 250mm with insulation "Rockwool FACADE.

The corner segment of the dome is designed as a glazed volume in metal structures Brick parapets are laid out from solid brick "Pobeda KNAUF". Windows - metal-plastic with double vacuum glass. Stained glass glazing - single-chamber double-glazed window and single glass. The lantern is made of metal structures with a special coating. Glazing - triplex with tempered glass EI 45. Entrance doors - aluminum stained glass and metal insulated. Partitions are made of aerated concrete and solid brick 120 mm thick, in "wet" rooms, followed by plastering. Lintels in brick walls reinforced concrete. bar GOST 948-84. The walls are monolithic reinforced concrete 200 mm thick. Partitions in wet rooms are made of solid brick 120 mm thick with subsequent plastering, partially glazed. Partitions, shown in dotted lines in the drawings, are made by the tenants themselves. GKL partitions were designed on both sides on a metal frame filled with mineral wool (TYPE OS 202 according to the album “GYPROC Complete Systems”, Issue 1) with a thickness of 125 mm EI 60. The walls are monolithic reinforced concrete with a thickness of 160 mm, 200 mm and 250 mm. Lintels in brick partitions - reinforced concrete. squared (GOST 948-84). Reinforced concrete are used for ventilation. ventilation units BV-33 400x800. In public premises, fine finishing of walls and ceilings is laid down (see "Register of finishing of premises"). The interior design of shops, lobbies and halls is carried out on a separate assignment. Cleaning is not provided for the rented premises. The project includes suspended ceilings "ARMSTRONG" and suspended ceilings made of gypsum plasterboard on metal rails.

Constructive decisions

The building is a single block measuring 64 x 35,5 m, consists of 9 floorspart and 1-storey underground parking. Building structures include pilefoundation, grillages slab on grillages, columns, external and internallongitudinal and transverse walls, walls of elevator shafts, ceilings and coverings, metalpersonal structures of the attic. At the moment, the construction site has been cleared, piling has been partially completed. drawing field. A cat dug up at the time of the examinationtrap is covered with construction debris. Parallel to the end wall of the house No. 2/20 lit. B at a distance of 1,65 m, a sheet pile was installedsteel sheet piling of the Larsen-4 profile, 12 m long. Majority tongue links do not have locks and are pressed in with a small gap. Pebefore performing excavation work on digging a pit, it is necessary to perform sealing the existing sheet piling by injection theredressing solutions or the organization of impervious curtains. According tobearing capacity sheet piling is not enough, the calculated deformations exceed the limit admissible. The project provides for the fastening of sheet piling duringinterchangeable supports at the time of work, and then structures underground parking during operation. In addition, to reduce the impact for house No. 2/20 lit. B, sheet piling along the axes is provided 21 and M from a steel sheet pile of the Larsen-4 profile, 12 m long. The project adopted a pile foundation. Used piles with a section of 350x350 mm cerii 1.011-1 issue 8 brand S220.35-Sv2,3, immersed to abs. elev. -22,200 by sta methodtic indentation. Part of the existing piles (124 pcs.) is used in the foundationstructures, the rest are cut down 400 mm below reinforced concrete structures and excludingget out of work. Light dusty loams were taken as the supporting layer of the pile foundation.wadded with gravel and pebbles (IGE-9, E = 120 kg/cm2, IL = 0,34, φ = 15 deg, c = 0,12 kg/cm2).  The value of the design load on the pile according to the test results is 125 tf. Piles have rigid pinching into the grillage plate, provided by the presence of reinforcement outletstours of piles embedded in the grillage slab by the amount of reinforcement anchoring. Pile bushes are combined into grillages 800 mm thick. Between grillages and under the walls of the 1-storey part are made of a grillage slab 500 mm thick. Foundationnye structures are made of concrete B30, W8, F150. The bearing system of a building of a communication type, i.e. take all horizontal loadstoil with diaphragms and stiffening cores. Spatial rigidity of the building obesIt is baked by the joint work of vertical load-bearing structures, united floor hard drives. Reinforced concrete columns of the building are taken with a section of 400x400 mm, 500x300 mm, 550x400 mm, 600x200 mm, 600x300 mm, 720x200 mm, 1000x200 mm, 1400x200 mm. InsideThe front and outer walls of the building are assumed to be 200 mm thick, the walls of the elevator shafts - 160 mm thick. Cover slab over a one-story underground parking at el. -1,400 in progress 300 mm thick, floor slab at elev. -0,070 - 230 mm thick, slabsroofing of a typical floor and covering of a 9-storey part - 200 mm thick.
