Introduction

Any building shall best meet its functional purpose. This means that the composition, dimensions, quantity and mutual arrangement of the rooms, the state of their air environment, the strength and stability of the building structures, their ability to protect the room from external climatic impacts and noise should be most consistent with the processes for which the building is built.

It is impossible to provide these processes only with construction tools. Therefore, the modern building is equipped with a large number of engineering and sanitary equipment systems: transport systems (elevators, escalators, lifts, etc.), cold and hot water supply, fire fighting, sewage, heating, ventilation and air conditioning, heat and gas supply, power supply, lighting, information (telephone, radio, television, alarm).

Any building as an artificially created environment has an ethical and aesthetic effect on a person. The organization of internal space must meet the ethical requirements of society. The appearance of the building, its interiors should be formed according to the laws of architectural composition.

The necessary building qualities are achieved by technical means, the application of which is regulated by the national "Construction Codes and Regulations" (SNiP). Various types of building classification are used in this regulation.

Source data.

The designed building is a 2-section, 9-story, 72-apartment, panel residential building.

The designed building has rectangular shape with overall dimensions in axes 14 = 48000, in axes AE = 15000.

Residential 9 storey building 31.05 m high and has two sections.

The construction area is the city of Krasnodar;

Structural diagram of the building - block-panel;

Number of sections - two-section residential building;

Foundations - piles;

Roof - large-sized reinforced concrete elements;

Stairs - prefabricated reinforced concrete platforms and marches;

Floors - solid, prefabricated reinforced concrete floor panels;

Average temperature of the coldest five-day tn5 = -190C

Outside air temperature of coldest days tn = -220C;

Average ambient temperature for the heating period tot. Per. = -190C

Heating period duration Z = 149 days.

GSOP = 26820C.W.

On each floor 4 apartments are designed: three-room 2, two-room-1, one-room-1.

Each apartment is equipped with central heating, cold and hot water supply, ventilation. The waste line is designed with the device of receiving valves in accordance with the instructions for garbage separation, the garbage chamber is located at ground level with the ramp device. The entrance to the residential building is provided on one side. Atmospheric water is drained by means of internal drain, with discharge to storm sewage system.

structural solutions of the building

The volumetric planning solution is justified by the functional and structural scheme of the building. The block section is a symmetrical regular structural system of vertical pillars made of load-bearing ceramic concrete volume blocks of the "lying glass" type with a size of 3.6x6x2.8 m, and panel inserts with wall panels attached to the volume blocks and floor slabs resting on them, embedded in a single spatial system with vertical and horizontal connections with a uniform distribution of structural stiffness, their masses, as well as.

The project is characterized by the main load-bearing structures - volumetric blocks of the "lying glass" type, which are a ceramic concrete monolithic spatial five-plane structure with ribbed longitudinal walls and a floor plate. Panel inserts and corridor part are formed by additional internal wall panels and solid slabs of floors resting on them on 2-3 sides.

Volumetric blocks are equipped at the factory with external wall panels, ventilation blocks and prefabricated partitions. External wall panels are made of 3 layered ceramic concrete panels with effective insulation (polystyrene foam) with discrete bonds. Partitions in volumetric blocks and in interblock space - non-bearing prefabricated ceramic concrete with a thickness of 60 mm.

Additional internal wall panels - prefabricated reinforced concrete with a thickness of 120 mm; inter-apartment - 140 and 160 mm. Slabs of the panel part are solid reinforced concrete with a thickness of 160 mm with support along the contour and 3 sides.

Bases

The foundations are accepted as piles, made of piles with a section of 350x350, with a length of 9 m according to the series 1.011.110 ex.1

After diving, the pile field is leveled by cutting the upper piles. The upper ends - pile heads are united by a monolithic pile cap. Pile caps are embedded in the pile pile for 300 m. Precast reinforced concrete pile from concrete M150 .

A pavement with a slope from the building of 0.03, consisting of asphalt concrete 50 mm, a gravel base 300 mm on compacted soil, is provided to protect the soil near the walls of the underground from seepage of atmospheric waters.

Technical underground

External walls are made of 250mm thick basement panels. Horizontal insulation is made of two layers of hydroisol on bitumen mastic. Vertical waterproofing is performed by coating with hot bitumen in 2 times. The height of the technical floor is 2.3 m. Pipelines (water supply, hot water supply, heat supply) are located in the technical floor. Entrance to the technical floor is carried out from the staircase of the building.

Walls

External walls are made of reinforced concrete panels p = 2500kg/m3, thickness 300 mm. Three-layer walls are manufactured with protective and finishing outer and inner layers 20 mm thick. Horizontal joints between panels of external walls are filled with elastic gaskets.

The finishing material for the outer panel layer is decorative mortar. The thickness of the decorative protective layer is 20 mm.

Internal walls of reinforced concrete panels with a thickness of 160mm. Partitions made of gypsum concrete slabs with thickness of 80mm, panels of partitions are installed on reinforced concrete slab of floor.

Loggias

Made of solid reinforced concrete slabs. Floors are made of mosaic concrete. The railings are lowered to the lower edge of the slab.
