Architectural and space-planning solutions

The gymnastic complex is a sports and training facility with rooms without stands for spectators with a year-round operation. The indoor sports facility (gymnastics complex) is located within the boundaries of the building site of the utility yard building to be demolished and is a brick one-two-story (without basement) building of a rectangular shape in plan with a flat combined exploited roof. The height of the one-story part is 5,85 m, the height of the 2-story part is 9,88 m, the dimensions in the plan are 48 m x 68 m in the axes. The building is designed with an asphalted utility yard (23.4 m x 32.4 m), connected from the west and east to the park by two gates with the possibility of fire trucks and garbage collection vehicles. Gates are made according to a separate project. The building is divided by the utility yard into two autonomously functioning parts, each of which has a separate entrance for visitors (one from the side of the South Road, the second from the opposite side). Both parts of the building have the same functional purpose, a similar set of premises and layout. In each of the two parts of the building on the ground floor, two gymnastic halls were designed for rhythmic and athletic gymnastics (the dimensions of the halls are in accordance with the design assignment) with locker rooms, showers, coaching and inventory rooms, a lobby group of premises, a water metering unit, an electrical panel room, an ITP , waste collection chamber. In the northern part of the building on the ground floor there are control rooms and a security room. On the second floor there are ventilation chambers, administrative premises and storerooms. The height of the gymnasiums is 4,80 m, the premises of the first floor are 4 m, the second floor is 40 m. In each part of the building, one staircase of the L4,20 type is designed. The project documentation provides for measures to ensure the accessibility of each of the two parts of the gymnastic complex for people with limited mobility at the level of the first floor in accordance with the Design Assignment (parking space in an open parking lot, ramp at the entrance, universal cabin for a public restroom). The dimensions of the openings, the width of the evacuation routes and the improvement of the adjacent territory are designed taking into account the requirements of SNiP 35-01-2001. To finish the facades, a hinged system with an air gap and cladding with porcelain stoneware slabs is used. Fillings of window and door openings are metal-plastic.

Structural and space-planning solutions.

The building of an indoor sports facility - 1-2 storey, of a normal level of responsibility, was designed on the site of the building being dismantled based on the results of a technical survey. The structural scheme of the designed building is a frame-wall system with load-bearing brick walls and columns. The spatial rigidity and stability of the building is ensured by the joint work of the longitudinal and transverse walls, stiffening cores, stairwells formed by brick walls and floor hard disks. The rigidity of the floor and cover disk is provided by pouring joints between the slabs and anchoring the slabs to the walls and to each other, welding the cover slabs to the embedded concrete belt. The calculation of load-bearing structures was carried out in accordance with SNiP 2.01.07-85*, SNiP II -22 -81*, SNiP 2.02.01 -83*, SNiP 52-01-2003. External walls - load-bearing brick 510 mm thick, 640 mm thick and consist of solid ceramic bricks of the KORPO 1NF / 100 / 2,0 / 50 / GOST 530-2007 brand on a solution of M 50, a heater from a mineral plate 50 mm thick and a hinged ventilation facade systems "Dektot XXI" (technical certificate No. 2434-09 dated 03.03.2009/XNUMX/XNUMX) with fixing to load-bearing walls. Internal walls - load-bearing brick 380 mm thick made of ceramic solid bricks of the brand KORPO 1NF / 100 / 2,0 / 50 / GOST 530-2007 on mortar M 50. Partitions - brick 120 mm thick from solid bricks and plasterboard 150 - 205 mm thick with fastening to a steel frame. Overlapping - prefabricated reinforced concrete hollow core slabs 220 mm high according to type series 1.141.1-KR, 1.141-1 issue. 61, 64. The slabs are supported on load-bearing walls and reinforced concrete beams. Floor beams - prefabricated reinforced concrete according to the type series 1.125 KL-3. The cross section of the beams is 400x400 mm from concrete of class B 30. Columns (pillars) - brick from solid brick brand KORPO 1NF / 100 / 2,0 / 50 / on a solution of M 100. The cross section of the pillars - 380x380 mm. Covering - prefabricated reinforced concrete ribbed slabs with a height of 400 mm, 450 mm according to the type series 1.465.1-16, 1.241.1 KL-3, 1.465.1-15, 1.142.1 KL-1. The fixing of the slabs is provided by welding to the mortgages of the monolithic reinforced concrete belt. Stairs - prefabricated reinforced concrete steps and slabs of landings on steel stringers and beams according to the type series 1.050.9-4.93. The class of concrete of prefabricated structures is B 15-B35. The material of steel structures is steel C 245 GOST 27772-88. The foundations were designed based on the results of engineering and geological surveys carried out at the construction site. The foundations are designed on a natural basis with the replacement of bulk soils with a sand cushion up to 600 mm thick made of medium-sized sand with compaction. Foundation design - strip of precast concrete blocks according to precast concrete slabs GOST 13580-85 and monolithic reinforced concrete free-standing, columnar. Along the edge of the foundations, a monolithic reinforced concrete belt is provided along the top of the slabs - a reinforced seam. At the base of the foundations, fine sands of medium density with characteristics e = 0,750, E = 180 kg / cm 2 and silty sands of medium density with characteristics e = 0,641, E = 100 kg / cm 2. The calculated resistance of the base soil is -1,4 kg / cm 2, the average pressure on the base is 1,27 kg / cm 2. The material of monolithic structures is concrete of class B 20, W6, F 100, reinforcement AI, AIII. The expected draft of the building is 2,1 cm. The maximum level of groundwater is at a depth of 0,2-0,8 m from the surface of the earth. Groundwater is slightly aggressive with respect to concrete of normal permeability. The project documentation provides for measures for anti-corrosion protection of foundations from groundwater: coating insulation, the use of low-permeability concrete. A relative elevation of 0,000 corresponds to an absolute elevation of + 3, 600 m. The building of the transformer substation is of a normal level of responsibility, designed according to the wall structural scheme of two prefabricated reinforced concrete volumetric blocks (underground and aboveground) of full factory readiness. Wall thickness - 70 mm, floors - 100 mm. The foundation for volumetric blocks is a monolithic reinforced concrete slab 300 mm thick on a sand cushion 500 mm thick. The material of prefabricated and monolithic structures is concrete of class B 20, W6, W12, W16, F 75, F 150, F 200. A relative elevation of 0,000 corresponds to an absolute elevation of +4.100 m.
