Brief description of the design object

The project provides for a major overhaul of the dormitory building. The number of floors is 9 plus a basement and a technical floor. The hostel building is composed of 4 residential blocks with a displacement of the longitudinal axes. Residential blocks are united by inserts in which stairwells and elevators are placed. The building was built in 1972. The building has a complex configuration in plan. The dimensions of the building along the extreme axes are 24,21x65,48m. According to the constructive scheme - a building with load-bearing external and internal longitudinal and transverse walls. The foundations under the load-bearing external and internal walls are strip of prefabricated concrete blocks and pillows. External and internal load-bearing walls are brick. Above basement floor, interfloor floors are made of prefabricated hollow-core slabs 220 mm thick. The stairs are two-flight, formed by reinforced concrete marches and prefabricated platforms. The covering is made of reinforced concrete ribbed slabs. The roof is combined, rolled, with an internal organized drain. Isoplast roofing on bituminous mastic. The building has central heating, water supply, sewerage. The building belongs to the II degree of fire resistance. According to functional fire hazard - class F 1.2. The premises located on the 1st floor have 2 (two) entrances from the front facade and 1 (one) exit to the end of the building. The total area of ​​the premises before the overhaul - 7335,70 m2; The total area of ​​premises after overhaul is 7903,48 m2. 

Architectural and construction solutions

The project provides for a major overhaul of the dormitory building. The design solution is determined by the main overall dimensions, the position of the supporting structures, the requirements of SNiP, as well as the Customer's instructions on the composition and functional interconnection of the premises. The design task was approved by the Customer, the planning structure with the name of the premises is given on the floor plans (see sheets from АР-14 to АР-18). For a relative mark of 0.000, the mark of the finished floor of the first floor was taken. Main building indicators: Useful (total) area, m2: 7903,48; Building volume, m29518,4: XNUMX. Walls. Brickwork of external and internal load-bearing walls, in general, complies with the requirements of regulatory documents. Defects and damage identified during the visual inspection (oblique hairline cracks with an opening width of 1 mm to 2,5 mm, spreading along the mortar joints and the body of bricks of the outer verst of the brickwork to a depth of ½ brick, mainly in the overwindow and window sill belts at marks 1- 4 floors, in some areas, the destruction of the outer verst of brickwork) are not critical, they do not lead to a decrease in the bearing capacity, strength and stability of structures. The overall integrity of the wall structures is preserved. Partitions. - non-reinforced ceramic hollow brick M125, half-brick thickness (120mm). Attach all partitions to load-bearing walls along "Node A", see AR-14-17, KM-KZh; - glass blocks, 190x190x80mm, length of each partition - 3,9 sq.m; - system of office partitions "Windows Panorama", plastic double-glazed windows: h=2.5 m, L=12 m, 4 doors (900x1200 mm), blind filling up to h=0.85, above - glazing. The type of partitions is selected in accordance with the purpose of the premises and meet the requirements of fire safety. window blocks. - existing windows filled with double-glazed windows remain, and in the embroidered openings it is planned to install windows: PVC block with energy-saving double-glazed window PVC profile "Gealan" or equivalent according to GOST 30674-77 double-glazed window according to "Pilkington". - repair and replacement in place of existing glass blocks; - to prevent the ingress of birds - the installation of gratings met. with a cell of 50x50 mm in the ventilation of the technical floor; Doors. - internal and external doors are partially replaced according to the purpose of the premises (plastic, fireproof metal doors are installed), see AR-1. - new doors are arranged according to the purpose of the premises (plastic, fireproof metal ones are installed), see AR-1. Floors. Wooden floor structures are replaced with concrete ones. The external floor covering is accepted depending on the purpose of the room. The floors are designed from a water- and chemical-resistant self-leveling floor made of low-flammable polymeric materials that are resistant to abrasion and stress, ceramic tiles. The composition of the floor is given in the finishing sheet (Sheet АР-1). Floor structures are shown on sheet АР-2. Constructive decisions. The structural design of the building remains unchanged. The project provides: • Punching new and expanding existing openings in the walls with a metal device. clips; • Installation of a metal ramp at the main entrance in the axes "6-7" / "A-G". The main parameters of the ramp design are designed taking into account the requirements of SNiP 35-01-2001 "ACCESSIBILITY OF BUILDINGS AND STRUCTURES FOR LOW-MOBILE POPULATION GROUPS" p.p. 3.27-33. The design of the ramp is designed for loads of 350 kg / m2 in accordance with SP 59.13330.2012 p.p. 5.2.13; • Reconstruction of elevators with reinforcement of shafts with metal structures and replacement of existing elevator equipment. P.p. 8 of the "General Regulations for the Equipment of Buildings with OTIS NEVA Models Elevators" warns of the need to install equipment in shafts whose walls are less than 130 mm thick (since expansion dowels cannot be used on them), using embedded parts. Attachment part - equivalent of embedded part. Attention! See sheet 13, 05-3.2012-14 - KR. Along the axis of the guides, on the side with a size of 700 mm from the axis of the cabin (on the inside of the shaft), do not install the two upper nuts on the fastener, welding the rods to the plates, with a minimum extension of the rod. Interior decoration. • Floor covering device: - wear-resistant homogeneous linoleum; - Self-leveling floors; - porcelain stoneware; - concrete evacuated floors "Tremeks" with hardening of the top layer with cement. quartz. mixes "Mastertop-300"; - linoleum with antistatic coating ...
