Space planning solutions

Space-planning solutions are developed on the basis of the town-planning concept of the quarter. The volume-spatial composition of the building is dictated by the configuration and orientation of the site to the cardinal points. The location and elevation of the building exclude the zone of continuous shading in the yard. The residential building has one fire compartment with an area of ​​not more than 2500 m2. The residential part of the house consists of six sections, on the 1st floor there are residential and technical premises. Residential premises are located at 2 - 21. The maximum height of the building from ground level to the parapet on the roof is 62.750m. All sections are 22-storey (22nd floor is technical). A total of 671 apartments have been designed in the residential building. The set of apartments in terms of the number of rooms is made in accordance with the customer's assignment, the current building codes, taking into account modern requirements for commercial housing. In the basement floor of the sections, the premises for the maintenance of the building are designed: ITP, cable entry rooms, a water metering pumping station, a fire extinguishing pumping station, a water metering unit, storage facilities for cleaning equipment. The entrance to the basement is through separate entrances from the yard. On the ground floor there are built-in and attached technical rooms: (electrical) and a control room. Entrances for these premises are isolated from the entrances to the residential sections. Also on the 1st floor are the entrance nodes to the residential part of the building. In each residential section, vestibules are designed to enter the residential part. In the lobby there are boxes for postal correspondence, as well as stands for information. Residents get into the house from the street, from the mark +1.200 through the entrance group. To ensure the convenience of people with limited mobility and the elderly, BK 450 lifts were installed. All residential floors have a height of 2.800 m. Also, technical rooms are located on the 22nd technical floor of the building: ventilation chambers and machine rooms of the elevator. All sections of the residential building have a staircase and elevator assembly, which is equipped with a smoke-free H1 staircase and two elevators: One elevator with a load capacity of 400 kg and the second with a load capacity of 1000 (for lifting fire departments). OTIS elevators with a machine room located on the technical floor. The elevators have their first stop at el. +1.200 - at the level of the first floor. The orientation of the windows of most apartments is mainly solved to the south, east and west, which provides maximum insolation and natural light. For illumination and insolation calculations, see relevant sections. All apartments are provided with glazed loggias and balconies. The premises of the apartments are zoned with the allocation of a daytime zone and a sleeping zone. The project provides for measures aimed at preventing criminal manifestations and their consequences in accordance with clause 8.8. SNiP 31-01-2003. The front doors are equipped with electronic locks with a tablet key, the doors of the technical rooms are provided with metal ones. To ensure monitoring of possible criminal manifestations in the local area, including at the garbage disposal sites, the project provides for a CCTV system (SOT). Television cameras are installed along the perimeter of all sections on the facades of the building, at the main entrances to the buildings. The central device of the SOT is a digital video recorder located in the control room with round-the-clock duty. Round-the-clock recording of video information from all television cameras and the creation of an archive of video data are provided for the possibility of using information in the analysis of incidents. Residential sections are provided with garbage chutes close to the stair-lift units. Removal of garbage occurs through garbage collection chambers with exits directly to the outside. For laying technical communications, it is planned to install communication shafts and channels fenced off with enclosing structures with a fire resistance rating of at least EI45. A residential building, starting from the 1st floor, is a building with load-bearing longitudinal and transverse walls made of prefabricated reinforced concrete 180 mm thick. External walls are prefabricated reinforced concrete with a thickness of 350 and 450 mm. The basement is designed in monolithic reinforced concrete walls with a thickness of 200 mm. The outer walls of the basement are 300 and 450 mm thick. On the ground floor - external walls are self-supporting brick 250mm thick and prefabricated reinforced concrete 350 and 450mm thick. The external insulation of the brick walls of the first floor was solved using the Rockwool insulation system Facade Butts with thin-layer decorative plaster. Internal partitions - from silicate blocks with a thickness of 80 mm of JSC "Pavlovsky Plant", inter-apartment - from silicate blocks with a thickness of 130 mm of JSC "Pavlovsky Plant" and monolithic reinforced concrete. Brick partitions 250 and 120 mm thick are also used. The basement ceilings are reinforced concrete monolithic, then prefabricated reinforced concrete 160 mm thick, stairs, ventilation blocks from standard prefabricated reinforced concrete products. Elevator shafts - reinforced concrete prefabricated. The main building structures of the building of the facility are provided with fire resistance limits and a fire hazard class that meet the requirements of the Technical Regulation on fire safety requirements No. 123-F3. For the residential part of the facility - load-bearing structures and walls of staircases are provided with a fire resistance limit of at least R120 and REI120, respectively; partitions separating common corridors from other rooms with a fire resistance rating of at least EI45; inter-apartment partitions with a fire resistance limit of at least EI30; interfloor ceilings with a fire resistance limit of at least REI45. The remaining building structures of the facility are provided in accordance with the requirements of the Technical Regulations on fire safety requirements No. 123-F3. The built-in technical rooms are separated from the residential part of the complex by a fire ceiling and walls of the 2nd type and from each other by fire barriers with fire resistance limits of at least REI45 and EI45. Enclosing structures of fire-hazardous premises (ventilation chambers, machine rooms of elevators, switchboards, technical rooms of the fire hazard category “B1÷B3”, etc.), storage rooms are made in the form of fire partitions of the 1st type (EI45) and fire ceilings 2 th type (REI60). Openings in these partitions are protected by fire doors of the 2nd type, i.e. with a fire resistance limit of at least EI30. Garbage collection chambers are distinguished by ceilings and partitions with a fire resistance limit of REI60. Filling openings in fire barriers (walls, ceilings and partitions) is accepted with a fire resistance limit corresponding to the type of fire barriers in accordance with the requirements. Technical regulation on fire safety requirements No. 123-F3. At the intersection of the enclosing structures of the premises with various engineering communications (air ducts, electrical cables, etc.), the holes and gaps formed are protected with non-combustible material until the fire resistance limit is equal to the fire resistance limit of the crossed structure. At the intersection of fire walls and partitions with air ducts of ventilation systems, fire-retardant dampers are provided with a fire resistance limit corresponding to the fire resistance limit of the structure being crossed. The roof is rolled flat, RockWool insulation RUF BATTS. Access to the roof is via stairwells. Internal drains are designed to drain water from the roof. Doors at the exit from the stairwells to the roof are provided with fire doors of the 2nd type and dimensions of at least 0.75 × 1.5 m. As a filling of window openings, window blocks made of PVC profiles with double-glazed windows with a reduced heat transfer resistance coefficient of 0.51m2Co/W were designed. Air exchange of residential and built-in premises is carried out through ventilation noise protection devices with sound insulation of at least 33 dB.

Structural scheme of the building

The structural system of the basement of the building is a wall system with load-bearing transverse and longitudinal walls. The spatial immutability of the basement is ensured by a set of monolithic reinforced concrete walls, floor slabs and rigid junctions of elements with each other. The junctions of the load-bearing walls with the grillage are rigid. The foundation of the building is a pile foundation, consisting of rows of driven piles and monolithic reinforced concrete slab grillages. The grillage is divided by temperature-shrinkage seams into 3 parts. Calculations of the structures of a residential building have been completed. As a result of the calculation of the spatial scheme of the building, the following parameters were determined: maximum and average settlements and heels of the building from the most unfavorable combinations of loads; maximum horizontal movement of the top of the building from the worst load combinations; maximum acceleration of floor vibrations from the pulsating component of the wind load (for high-rise blocks); stability factor of high-rise blocks; forces in monolithic walls, piers and floor slabs. In accordance with the efforts received, the working reinforcement was selected, the strength and deformability of monolithic reinforced concrete elements of the basement and the first floor of the building were checked. Calculations have shown that stresses, deformations, displacements, crack openings do not exceed the corresponding limit values ​​of building codes for designing structures or foundations.
