Architectural solutions.

Basic space-planning solutions. On the ground floor of the shopping complex there is a closed parking lot for 16 cars. Loading of goods is carried out from the first floor of the built-in parking. On the second floor there are commercial premises. The third floor houses utility and technical rooms. Auxiliary and engineering premises are located on the first third and fourth floors. The main entrance to the building is from the Bolshoy Ave. PS. The second exit is provided to the courtyard. The building provides for two staircases and two passenger-and-freight elevators with a carrying capacity of 650 kg. External finishing of facades. When designing, much attention was paid to the architectural design of the facades; several options for a three-dimensional solution were made. The selected option is distinguished by a bright color scheme of the facades, a variety of architectural elements and details. High-quality plaster is used for finishing the facade - smooth and with rusticated seams. The plinth is faced with ceramic - granite tiles, which highlights the base of the building in relief. Window openings are filled with single-chamber double-glazed windows in a plastic cover with filling between the glass space with argon, with an outer coating of a double-glazed window with a mirror film that reflects light. Interior decoration. Modern high-quality materials are used in interior decoration. The floors of corridors, office premises are made of ceramic granite slabs 300x300mm in size. In technical and auxiliary rooms, the floors are made on the basis of a cement-sand mortar, as well as from linoleum. The walls of commercial and office premises are covered with decorative water-based paint. In bathrooms and technical rooms, the walls are covered with ceramic tiles of various colors. The ceilings of the 2nd and 3rd floors are painted with decorative water-based paint, in offices it is possible to use suspended acoustic ceilings of the Akusto, Armstrong, Ecophon type with a painted aluminum supporting structure complete with fasteners and accessories. - All materials used on evacuation routes must have fire hazard indicators not exceeding the following requirements: - for finishing walls, ceilings in lobbies, stairwells, elevator lobbies - G1, V1, D2, T2. - for finishing walls, ceilings and filling suspended ceilings in common corridors, halls - G2, V2, D3, T3 or G2, V3, D2, T2. - for floor coverings in lobbies, stairwells, elevator lobbies - G2, RP2, D2, T2. - for floor coverings in common corridors, halls - B2, RP2, D3, T2. The roof is operated with an internal drain (with electric heating) and a slope of 1.5%. The enclosing structures of the roof are made of ceramic tiles on a sand-cement screed, two layers of isoplast, welded onto rigid mineral slabs RUF BATTS B, 40-360 mm thick (to create the necessary slope). The lower layer of insulation consists of a mineral plate RUF BATTS H 100mm. Lighting solutions. All premises with a permanent stay of people have natural lighting. Calculation of KEO for normalized premises is carried out. The level of natural and artificial lighting of the premises complies with the requirements of SanPiN 2.2.1/2.2.1.1278-03. The calculations were made in accordance with SP-23-102-2003 Natural lighting of residential and public buildings. According to Table 2 SanPiN 2.2.1/2.1.1.1278-03 KEO of trading floors is not standardized. According to Table 2 SanPiN 2.2.1/2.1.1.1278-03 KEO is standardized for offices. Normalized KEO in natural light - with side lighting for offices with a room depth of less than 5 m: en = 1,0%, (according to Table 4 of SP 23-102-2003) with side lighting for offices with a room depth of more than 5 m: en = 0,7, 6%, (according to Table 23 of SP 102-2003-200) The calculations showed that the calculated KEO complies with the standard. Artificial lighting is designed with luminaires with fluorescent lamps providing artificial lighting levels in sales areas - 150lx, in utility rooms 75lx. knots XNUMX lux. Basic solutions for protection against noise and vibration. The ventilation systems are the main source of noise in the building. To combat the spread of aerodynamic and mechanical noise in the premises, which occurs during the operation of ventilation units, the following measures are provided: ventilation units are located in isolated rooms; connection of air ducts with fans is carried out using flexible connectors; the accepted speeds of air movement in ventilation systems are not higher than the permissible ones; fan operation is selected in the maximum efficiency mode; ventilation systems have silencers.

Constructive decisions

Basic design solutions. The constructive scheme of the TC building is framed, and consists of columns, beams, floor slabs and stiffening diaphragms (staircase walls), all frame elements are made of monolithic reinforced concrete. The foundations are provided for piles of bored piles according to the Fundex technology with a diameter of 450 mm, a length of 18 m, a total of 119 pcs. The bearing capacity of one pile according to the results of static sounding carried out during geological surveys is N = 80 tons. Piles are made from the surface of the earth. Before the start of construction, two bushes are provided for static testing of two piles. Bushes of piles of 2-6 pieces are provided under the frame. in each, the bushes are located in the places where the columns are arranged. Piles are reinforced to the full length with welded frames, with working reinforcement Ø18 A400, 6 pcs. After the installation of the pile heads, they are cut down to -0,750 mark and grillages are arranged. The pile heads are driven into the grillage by 50 mm. The grillages are united by a system of cross beams, the height of the beams and grillages is 600 mm, the width of the beams is 600-800 mm, the beams are reinforced with knitted frames. Concreting of grillages and beams is carried out in two stages: 1st stage - up to el. -0,450, further dismantling of the formwork, installation of sleeves and outlets eng. networks, backfilling of crushed stone and the device of concrete preparation, then knitting the reinforcement of the slab and concreting to the mark. . At the top of the section, all beams and grillages are united by a reinforced concrete slab 250 mm, the upper edge of which coincides with the top of the grillages and beams (elevation -0,200). Under the grillages and the slab, concrete preparation is provided from B10 concrete, 100 mm thick. Under the slab, crushed stone preparation is arranged with tamping from crushed stone fr.20 ... 40 mm, at least 350 mm thick. The ends of the grillages are to be coated with a waterproofing compound based on bituminous mastic and insulated with Penopex 35 slabs, 50 mm thick. Before designing in 2010...2011, specialists carried out a technical survey of the structures of the surrounding buildings, which are included in the risk zone of new construction. Based on the survey data, a project was developed to strengthen the main load-bearing structures of these buildings. The strengthening project provides for partial transplantation and strengthening of the foundations with inclined piles using the TITAN technology, the length of the pile is 17 m, dia. 150 mm. The piles are located along the ends of the walls adjacent to the new building with a step of 1 m. The bearing capacity of the piles is at least 16 tons, so after transplanting, about 30% of the load from the walls will be transferred to the piles, which will avoid settlements of more than 2 cm. To increase the rigidity of the existing rubble foundations, before the installation of the TITAN piles, the body of the foundations is strengthened with pressure testing of the “foundation-base” contact zone. Strengthening is carried out through inclined boreholes dia. 42 mm, by injection of cement mortar under pressure. It also provides for the restoration of the destroyed sections of the foundations in the basement, the replacement of emergency jumpers with new ones. Reinforcement of brick walls by re-laying masonry sections along the main cracks along the end walls, tying the end sections with steel strands from channels 16P and smooth reinforcement 30 mm in diameter. The strands are installed at the levels of the two upper floors.
