Engineering Specification

It is necessary to design a single-section multi-storey residential building. The construction site of Saransk. We select the panel arceless structural scheme of the building. Number of floors 9. Design shall be carried out in compliance with accepted norms and regulations (SNiP 2.01.0182, SNiP 230199 *, SNiP II379 *.)

Space-planning solution of the building

The designed building is located in the city of Saransk.

Designed a 9-storey residential building for 36 apartments. Including: two-room apartments - 18, three-room apartments - 18.

The building has: one stairwell; and an elevator with a lifting capacity of 400 kg, entering the stairwell; trash duct (400 mm diameter)

On each typical designed floor there are 4 apartments: 2 - two-room and 2 - three-room. Apartments are designed in accordance with SNiP requirements.

Residential/The total area of apartments is:

- two-room - 30.36 m2/55.43 m2 and 2.94 m2 loggium;

- three-room - 47.04 m2/86.61 m2 and 5.83 m2 loggium.

In two-room and three-room apartments, the bathroom is separate. Inter-apartment walls are designed in such a way as to increase comfort in terms of sound insulation. In the basement of the building there are a boiler room, exhaust and ventilation chambers, hot and cold water and heating pipelines, elevator and water metering units.

In the attic there is an exit to the roof, a pipeline system, a shaft of ventilation channels, an engine room.

The residential building is equipped with one main entrance, through which residents get to the first floor to the elevators.

The height of the floor in the basement is 2.63 m, in the attic - variable (minimum - 1.8 m), on typical floors - 3.0 m 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.

Exhaust from apartments is represented by ventilation channels. Through the mines, air from all apartments enters the insulated attic room, and then it is discharged through the opening provided in the roof into the atmosphere.

The watershed is located throughout the height of the building. The drain pipe passes next to the elevator shafts. A water intake funnel is equipped on the roof, entering which rainwater is removed through pipes to the city sewage system.

Structural solution of the building

In the designed nine-story residential building, a panel arceless structural system is adopted. The floor height from floor to floor is accepted as 300 cm. The bearing walls are external and internal walls.

Structure Description:

- base - soil, permissible load on soil - 20 t/sq.m.;

- foundations - assembled reinforced concrete strip.;

Ground freezing depth for Cheboksary is 150 cm.

Wall wall panels of the basement are installed on the foundation, which are connected to each other in the same way as panels of overlying floors. The basement outer panels have a thickness of 350 mm and the inner panels have a thickness of 180 mm.

To protect the basement walls from capillary moisture, horizontal waterproofing is laid along the surface aligned with cement mortar, located at the level of the basement top and lined with facing tiles. Around the building along the external walls there is a pavement with a slope from the wall

Exhaust from the building and its ventilation is carried out through special ventilation channels into a warm attic, which is equipped with a ventilation shaft

- floor slabs are made of reinforced concrete slabs of continuous section with thickness of 160 mm from concrete of grade 200.

- The walls of the building are designed from three-layer reinforced concrete panels (ceramic concrete) with a thickness of 350 mm. In three-layer panels, the load from the mass of the outer concrete layer and insulation is transmitted through flexible connections to the inner concrete layer. Outer layer of ceramic concrete 70 mm thick and reinforced with steel mesh. The outer layer is plastered and stained. The bearing inner layer is accepted with a thickness of 100 mm according to the conditions of anchoring steel connecting elements in it (embedded parts, reinforcement outlets, etc.). Foam polystyrene is used as insulation layer.

Internal bearing walls are made of reinforced concrete panels 180 mm thick.

Thermal insulation of vertical and horizontal joints is provided by thermal plates made of polystyrene foam. Vertical thermal plates from outside are protected by adhesive air insulation from weatherproof tapes. The mouths of the joints of the basement panels are carved with cement mortar of grade 100 in the warm season. Mouths of joints outside are primed and then filled with elastic sealing gaskets and sealing mastic with protective coating.

- The ladder lift group includes a non-smokable staircase of type 1 and an elevator with a carrying capacity of 400 kg. The ladder marches have a U-shaped section. The size of the step tread is 300 mm, and the riser is 150 mm. Stair platforms are supported by transverse reinforced concrete wall panels.

- Attic roof with internal drain; "warm" attic. The attic floor is three-layer from 240mm thick mills and 240 mm thick mineral wool plates with a slope of 0.05.

- Floors in residential premises are made of laminate with use of soundproofing and laying substrate Arbiton with thickness of 10 mm, in bathrooms - from ceramic tiles, in inter-apartment corridors, in the basement and attic - concrete.

- In the roof there are 2 rainwater funnels, which direct atmospheric water to the network of drains with closed water outlets to the system of underground drains.

- Entrance group consisting of porch, vestibule.

- The technical underground is intended for internal utilities.

- sanitary units - from fully finished and equipped at the factory unified volumetric gypsum concrete cabins with reinforced concrete pallet;

- ventilation units - gypsum concrete not bearing, height per floor;

- loggia - reinforced concrete slabs resting on external walls.

- inter-room partitions made of gypsum concrete.

Light Engineering Calculation

We choose the area of ​ ​ the window based on the condition: Sok = Spol/8 soundSpol/5.

As an example, consider the choice of filling light openings in a three-room apartment.

Living room 1: Sok = 20.98/8 = 2.63 m2 20.98/5 = 4.20 m2

From the available standard windows, we accept the window with dimensions 2100 * 1500. The area of ​ ​ such a window is 3.15 m2, which meets the requirement for the illumination of the room with natural light.

Living room 2: Sok = 16.96/8 = 2.12 m2 16.96/5 = 3.39 m2

From the available standard windows, we accept the window with dimensions 2100 * 1500. The area of ​ ​ such a window is 3.15 m2, which meets the requirement for the illumination of the room with natural light.

Kuzhnya1: Sok = 11.73/8 = 1.47 m2 sound11.73/5 = 2.35 m2

From the available standard windows, we accept the window with dimensions 1500 * 1500. The area of ​ ​ such a window is 2.25 m2, which meets the requirement for the illumination of the room with natural light.

Kuzhnya2: Sok = 11.38/8 = 1.42 m2 sound11.38/5 = 2.28 m2

From the available standard windows, we accept the window with dimensions 1800 * 1500. The area of ​ ​ such a window is 2.7 m2, which approximately corresponds to the requirement for the illumination of the room with natural light

Bedroom 1: Sok = 13.03/8 = 1.63 m2 A/R = 2.61 m2

From the available standard windows, we accept the window with dimensions 1900 * 1500. The area of ​ ​ such a window is 2.3m2, which approximately corresponds to the requirement for the illumination of the room with natural light.

Bedroom 2: Sok = 13.03/8 = 1.63 m2 A/R = 2.61 m2

From the available standard windows, we accept the window with dimensions 1500 * 1500. The area of ​ ​ such a window is 2.25m2, which meets the requirement for the illumination of the room with natural light.
