Structural and space-planning solutions

The level of responsibility of the building is II, normal. In accordance with the technical conclusion on the inspection of structures, the existing building of the sports and recreation complex and the bathhouse was built according to a frameless beam design scheme. At the time of the survey, the building is in operation. Frame columns with a section of 400 x 400 mm, mesh 6 x 6 m (in the pool room 6 x 12 m). Ceilings and covering - plates 200 mm thick, in the pool area - with beams with a section of 500 x 750 (H) mm. Bearing structures are made of monolithic reinforced concrete class B25, working reinforcement class A-III. The internal walls of the stairwells are made of solid clay bricks 250 mm thick. External walls - non-bearing, solid brick 250 mm thick, mineral wool insulation and ventilated facade. All supporting structures are in good condition. The foundations of the building are piled. Piles - bored injection diameter 250 mm, columnar bush grillages, united by a floor slab. In accordance with the report on engineering and geological surveys, at the base of the tip of the piles - plastic sandy loam with the characteristics E = 125 kg/cm2, JL = 0,38. According to the results of the static test, the design load is assumed to be 50 tf. A verification calculation of existing structures for design loads from reconstruction was carried out. The bearing capacity of walls, columns, foundations and foundations is sufficient to absorb design loads from reconstruction; the structures do not require reinforcement. The settlement of foundations does not exceed 1,0 cm. According to the results of the calculation, reinforcement of floor slabs in the punching zone is required. In accordance with the change in space-planning decisions, the reconstruction of the building provides for: dismantling of partitions; punching openings in external non-bearing walls with the installation of jumpers from rolled corners, pulled together with studs; sealing existing holes in the ceilings with monolithic reinforced concrete of class B 25 with reinforcement according to the calculation; reinforcement of the capital part of the floors in the zone of punching by the column by increasing the thickness of the floor to 285 mm and installing transverse reinforcement; on the first floor of the building, the installation of a rectangular pool bowl (instead of the previously designed round shape) made of monolithic reinforced concrete of class B25, W4, wall and bottom thickness 250 mm, depth 1,45 m; installation on the roof of the building of a steel tie frame of superstructures for various functional purposes, consisting of steel pipes of square section welded together; arrangement on the roof of the building of a tie frame of a terrace with load-bearing elements made of wooden beams and sheathing with a wooden lath; to install the equipment, a system of beams made of rolled steel profiles with hinged fastening on chemical anchors to existing columns is provided. New structures are designed on the basis of the calculation performed on the PC SCAD 11.5. During the construction and installation work on the reconstruction of the building, it is planned to monitor the load-bearing structures of the building. The impact of the reconstruction on the surrounding buildings is not expected.
