Construction of MWC

1. General plan.

For the construction of the MZHK, a site was selected on the territory of the projected microdistrict of the city of Belozersky .

The construction site is located in the northern part of the projected microdistrict. The northeastern part of the site overlooks the main street of the village. The north-western faces the projected territory of the village-wide park. The southeastern part faces the main square and the pedestrian boulevard, the southwestern to the inner-district transport passage.

The complex is designed for 879 apartments and 2932 residents and consists of 7 residential buildings (6 nine-story and 1 16-story), a school building with 1298 seats, a kindergarten-nursery with 330 seats and a 2-story public center.

The complex is considered in the inextricable unity of all its material and spatial components:

- apartments - primary cells,

- groups of apartments combined with one floor in a section,

- residential building,

- community center,

- schools,

- kindergarten,

- the territory of the site.

Each of these elements carries a certain household, social and socio-organizational burden.

Space-spatial and planning solutions of the complex are determined by taking into account the following factors:

- the location of the complex in the structure of the village and, in particular, in the vicinity of the socio-shopping center.

- Necessity of architectural formation of the main street of the village on its most responsible section.

- Size of investments, which determine the volume of construction and the order of commissioning of facilities.

- Structural features of the social organization of the complex.

- Architectural and artistic tasks of space organization, minimum radii of public service, creation of conditions for public contacts, recreation and sports.

As a result of the variant design, the optimal option was chosen, in which the volume of apartments in the amount of 100150 units per 300450 inhabitants was accepted. This option corresponds to economic and structural social considerations, as well as the size of investments for construction within the regulatory time frame.

Thus, the formation of the master plan of the construction area will be as follows:

1. Along the main street on the northeast side of the site are three repeating buildings No. 1,2 and 3, in the alignment.

2. Along the northwest side, opposite the future park are buildings No. 4 and No. 5.

3. The southeast side is formed by buildings No. 6 and No. 7. Building No. 6 forms the space of the pedestrian boulevard, and building No. 7 is the vertical dominant in the composition of the main square of the village.

4. The kindergarten-nursery is designed only for the needs of the district and is located at an equal distance from all residential buildings of the construction district.

5. The school is designed to serve two blocks and is located on the southern border of the construction site.

6. Transportation service is provided in the form of dead ends along the outer circumference of the section. (Guest parking lots, waste disposal areas, etc.)

7. Each building has its own house space adjacent to the boulevard and fenced off from it by shrubs. There are playgrounds and recreation grounds for the elderly.

8. Utility sites are located on the outside of the development near the sites for garbage collectors

5. Architectural - planning solution.

Designed a 16-storey 1-section residential building according to

The section has an unnamed staircase with ventilation shafts and two elevators with a lifting capacity of 630 and 400 kg - one passenger, the other passenger, leaving the elevator hall, separated from the corridors by partitions with doors.

In the house, a garbage duct is designed, placed in near the elevators with intake valves on each floor and a garbage chamber in the basement room, which has access to the courtyard .

Apartments designed in accordance with SNiP requirements

Access to the balcony or loggia is provided in each apartment. The apartments provide for the location of separate bathrooms. Kitchens and bathrooms with larger sizes are designed.

Bearing walls are arranged so that they separate apartments from corridors and from each other, increasing comfort in terms of sound insulation.

On the technical floor there are elevator rooms. Elevator rooms do not have adjacent walls with living spaces.

The house is equipped with two separate entrances, overlooking the courtyard through which residents get to the first floor. The height of the floor is 2.8m from floor to floor.

Water enters the building through the central water supply of the microdistrict, sewerage is connected to the central sewerage network of the city, as well as all other engineering networks of the building.

Building characteristics:

Durability - II

Degree of fire resistance - I

Building class - II

Orientation is meridional.

The ratio of the working (residential) area of ​ ​ apartments to the total (useful) will be :

K1 = 5120/9024 = 0.57

K1 values correspond to standard: K1 (0.50.75)

The construction volume of the above-ground part of the building is 35453m3. Then the coefficient characterizing the economic efficiency of the building, equal to the ratio of the building volume to its living area, will be equal to:

K2 = 35453/5120 = 6.92 m3/sq.m

The compactness factor of the plan, equal to the ratio of the perimeter of the outer walls to the total area, is:

K3 = 136.2 m/730.8 m2 = 0.186 m/m2 (norm. K3 = 0,160,25).

Coefficient characterizing the degree of saturation of the building plan with vertical structures, equal to the ratio of the structural area of ​ ​ the vertical structure to the building development area:

K4 = 74.2/730.8 = 0.11 (norm. K4 = 0,10,2).

6. Architectural - structural solution of the building.

The designed building has 16 floors. It is made of prefabricated reinforced concrete and brick and has a arceless scheme with transverse and longitudinal bearing walls. The main pitch of the transverse bearing walls is 3.0-3.6 m. Enclosing structures - brick with insulation.

The accepted structural diagram of the building provides strength, rigidity and stability at the erection stage and during operation under the action of all design loads and impacts.

Vertical loads from floors are perceived and transmitted to the foundation of the base by transverse and longitudinal walls at the same time.

A prefabricated reinforced concrete foundation is designed under the building. Foundation base at elevation 155.20 (- 3.30). The base, according to Geotrest, is composed of refractory loams with sands of sand and sands that are dusty, medium-density, wet, as well as large-shell sands. The groundwater level is located at a depth of 7.9 m. Design soil resistance of the base is accepted as 2.50 kN/mq. on the weakest soil - the sands are dusty.

Basement walls located on the soil side shall be protected by continuous dressing waterproofing, roll waterproofing is arranged under the basement floor. First of all, an external pond is arranged to divert atmospheric water from the territory of the construction site. After the construction of the underground part, arrange a waterproof pavement with a width of at least 1.0 m.

Under all foundation slabs we arrange concrete preparation with thickness of 100mm from concrete of class B7.5.

Floors are covered by slabs resting on three and two sides. The floor consists of multi-pillar plates with a thickness of 220 mm, factory made. Loggium slabs have a non-rectangular shape, also factory-made from frost-resistant concrete.
