Architectural and space-planning solutions

A multi-apartment residential building was designed, consisting of block A - a residential part and block B - an attached part. The main facade of the building is oriented towards the projected street of the Shushary settlement. Entrances to the building are designed from the side of the yard area and intra-block passage. For the relative mark of 0,000, the level of the finished floor of the first floor, corresponding to the absolute mark of 18.50 m, was taken. The building is rectangular in plan, with dimensions in the extreme axes 111,34 x 17,3 m. The maximum height of the building from the planning ground level to the level of the parapet of the staircase and elevator units is 33,4 m. The residential part of the building, block A - 5-section, 10-storey, with a technical attic and a technical underground. Residential apartments are designed from the 1st to the 10th floors. There is also an electrical panel on the first floor. The height of residential floors is 2,70 m. At the level of +27,25 m, a technical attic is provided for laying engineering networks. The height of the technical attic rooms is 1,75 m. The technical underground was designed at the level of -2,580 m. The height of the technical underground premises is 2,42 m, The technical underground is intended for laying engineering networks, for arranging a cable entry room, a pumping station room, a water metering unit, and an ITP. Entrances to the technical underground are designed in each section through pits isolated from the residential part of the house. Five stair-lift blocks with entrance vestibules have been designed. Each section has an elevator with a capacity of 630 kg. The machine rooms of the elevators are designed at elevation +28,270 m. The outer walls of block A are made of AEROC aerated concrete blocks with mineral wool insulation and an outer decorative plaster layer along the grid, followed by painting. Internal walls and partitions - monolithic reinforced concrete. The cover is flat and insulated. The roof is rolled, the drain is internal. Windows and balcony doors are designed metal-plastic with double-glazed windows. The apartments have balconies without glazing. The design documentation does not provide for the finishing of residential apartments. The attached part of the building (block B) is designed as a 3-storey building with a basement. The attached block provides premises for the accommodation of local governments and non-profit organizations related to the residence of the population. Administrative premises, rooms for eating, rooms for storing documents, a room for storing cleaning equipment have been designed. There are sanitary facilities on each floor. Each floor has two emergency exits. The height of the above-ground floors of the attached block B is 3,60 m. The basement floor of block B provides for the laying of engineering networks, the design of the premises for the water metering unit and cable entry, ITP. The height of the ground floor premises is 2,76 m. The outer walls of block B are made of monolithic reinforced concrete with mineral wool insulation and an outer decorative plaster layer along the grid, followed by painting. Partitions - GKL sheets on a metal frame filled with mineral wool. Coating - flat, combined, insulated. The roof is rolled, the drain is internal. The windows are designed metal-plastic with double-glazed windows. The project documentation provides for measures to ensure the life of the disabled. accessibility for MGN of all premises of the attached block B and all residential apartments is provided. A ramp has been designed at the entrance to the attached premises. On the first floor of the attached premises, a sanitary unit with a universal cabin for MGN is provided.

Structural and space-planning solutions

Building responsibility level – II (normal). The building is divided by sedimentary seams into two blocks - A and B. Block A is also divided into two parts by a sedimentary seam. Block A is designed from monolithic reinforced concrete. The structural system of block A is a cross-wall system with a variable pitch of the transverse walls from 3,0 to 4,8 m. The outer walls of the basement are three-layer monolithic reinforced concrete, 160 mm and 120 mm thick with an inner layer of effective insulation 100 mm thick. The bearing walls of the basement are monolithic reinforced concrete, 180 mm thick. Ceilings - monolithic reinforced concrete, 160 mm thick. Internal walls - monolithic reinforced concrete, 160 mm thick. The material of the basement load-bearing structures is concrete of class B25, F75, W6, for other structures - concrete of class B25, F75, reinforcement of class A500C. The outer end walls are load-bearing, three-layer, made of monolithic reinforced concrete 160 mm thick, effective insulation and facade plaster. External non-bearing walls - three-layer, made of aerated concrete blocks of class B2,5, grade D600, F25 250 mm thick, effective insulation and front layer of facade plaster. Fastening to load-bearing structures and connection of layers is carried out by flexible connections with anti-corrosion coating. Stairs - prefabricated reinforced concrete marches. Elevator shafts and ventilation blocks are prefabricated reinforced concrete. Block B is designed from monolithic reinforced concrete according to the column-wall structural scheme. the maximum column spacing is 5,1 x 5,5 m. Bearing structures - walls 160 mm thick, columns with a section 400 x 400 mm, floors - beamless monolithic 160 mm thick. Stair flights - monolithic reinforced concrete. External walls - load-bearing multi-layer of monolithic reinforced concrete 160 mm thick, effective insulation and plaster on the grid. Fixing the insulation on the dowels. The material of the supporting structures of the zero cycle is concrete of class B25, F100, W6, for other structures - concrete of class B20, B25, F100, reinforcement of class A500C. The spatial rigidity and stability of the building is ensured by the joint work of vertical elements united by floor hard disks. The calculation of the load-bearing structures of the building was carried out using the Monomakh and SCAD software packages. The relative mark of 0,000 is taken as the absolute mark of 18.50. The foundations of the blocks are designed on a natural basis, in the form of monolithic reinforced concrete slabs 600 mm thick, concrete B25, W6, F150. Under the foundation, a concrete preparation 50 mm thick is provided along the leveling layer of sand. In accordance with the report on engineering and geological surveys, the foundation is the EGE-2 soil - brownish-gray plastic sandy loam with pebbles, with sand nests, with characteristics φ=25º, c=0,31 kgf/cm2, E=100 kgf /cm2. The calculated soil resistance of the base is 2,85 kgf / cm2, the average pressure under the sole is 1,30 kgf / cm2, the expected draft is 6,0 cm. The design documentation provides for measures to protect the basement from groundwater: coating insulation of walls, the use of low-permeability concrete.
