Engineering Specification

It is necessary to design a multi-storey residential building according to the program: "Social housing" with a storey from 9 to 17. (frame type, series type, construction area at the student's discretion).

We choose:

- panel arceless structural diagram of the building.

- an ordinary section of a 17-story residential building with an unnamed stairwell.

- climatic construction district of Belgorod.

Design shall be carried out in compliance with accepted norms and rules (SNiP 2.010182)

Space-planning solution of the building

The designed building of the ordinary section has 17 floors.

On each designed floor of one section there are 4 apartments: 2 - one-room and 2 - two-room.

Each apartment has a separate kitchen, separate bathroom and bathroom.

On each floor, from public areas there are: an elevator hall, a tambour, a tambour with a trash hatch, a loggia with access to an unnamed stairwell.

One-bedroom apartments have a living area of ​ ​ 31.51 m2, and a total area of ​ ​ 38 , 69m2,

Two-room on the end side has a living area of ​ ​ 38.8 m2, total - 52.43 m2

In total, the designed house (ordinary section) has:

35 one-room apartments;

33 two-room apartments.

The residential area of ​ ​ the apartments of the designed house is 2367 m2.

The total area of ​ ​ apartments is 3085 m2.

The section provides room for Wheelchair 15.5m2, room for garbage chamber -7.63m2

Structural solution of the building

In the designed seventeen-story residential building, a panel arceless structural system with a cross pitch of 360 cm is adopted, the height of the floor from floor to floor is 280 cm. The bearing walls are external and internal walls.

Foundations tape prefabricated on soil.

Depth of laying is equal to 3.0m. The foundation is made of reinforced concrete slabs - pillows of type F16 (F16/2) and F12 (F12/2), as well as concrete basement slabs that are basement walls.

Basement walls located on the soil side shall be protected by continuous coating waterproofing (coating with hot bitumen in two times).

Floor slabs are made of reinforced concrete slabs of continuous cross section with thickness of 180 mm from concrete of grade 200.

The walls of the building are designed from three-layer reinforced concrete panels (ceramic concrete) 320 mm thick. 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.

The outer layer is designed with a thickness of at least 80 mm and reinforced with a steel mesh on demand of durability.

In addition to the main concrete layers, the panel contains an external protective-finishing layer and an internal finishing layer.

Facade protective-finishing layer of light-concrete panels is made of steam-permeable decorative concrete and mortars, or from conventional solutions with the following factory color .

The bearing inner layer is accepted with a thickness of at least 120 mm according to the conditions of anchoring steel connecting elements in it (embedded parts, reinforcement outlets, etc.). Materials with thermal conductivity coefficient within the range of 0.04 0.10 W/m ° C - in the form of blocks, plates or mats - mineral-cotton mats and polystyrene foam plates are used as insulation layer .

Internal bearing walls are made of reinforced concrete panels with thickness of 160 and 180 mm. Drained joints are used on panel grid faces.

Slab and inner wall panel are inserted into slots at top and side faces of panels, respectively.

The resulting vertical well is frozen with structural concrete of grade 200.

Thermal insulation of vertical and horizontal joints is provided by thermal plates made of non-combustible rigid mineral wool panels.

Vertical thermal plates from outside are protected by glued 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 staircase group includes an unnamed staircase, two elevators with a carrying capacity of 400 kg and one carrying capacity of 900 kg.

The unpopulated staircase provides access to all residential floors, the elevator room and the roof.

The stairs are two-march .

This designed house uses stairways and ribbed platforms. The stairways have a frieze stage and 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. Stairs - prefabricated reinforced concrete from marches 1.0 m wide.

Attic roof with internal drain; "cold" attic. The roof is hydro-insulated with asphalt-based roll materials in several layers. The insulation of the attic floor is hard mineral wool plates 200 mm thick.

Floors in residential premises are made of parquet, in bathrooms, in inter-apartment corridors and public areas - from ceramic tiles, in the basement and attic - concrete.

In the roof there are 2 rainwater funnels that direct atmospheric water to a network of drains with closed water outlets to the storm sewage system.

Entrance group, consisting of a porch, vestibule, lobby and elevator hall.

A staircase is provided from the lobby (elevation 0.600) to the ground floor level (elevation -0.020).

The technical underground is intended for internal utilities.
