The designed hospital facility without special requirements for placement (maternity hospital) is a separate, polygonal building in plan, has a basement, basement and six above-ground floors. The height of the building from the ground level to the top of the parapet is 20,35 m. The level of the finished floor of the first floor, corresponding to the absolute mark of +0,000, is taken as a relative mark of 12.50. The building consists of the following functional blocks: a maternity hospital with 21 beds, a hospital with 72 beds, and a rehabilitation treatment department. In the basement part of the floor at elev. -3,300, it is planned to place a rehabilitation treatment department with a swimming pool, laundry, food preparation rooms as part of the catering department, service and auxiliary premises. In the basement - premises for the placement of engineering equipment. Along the outer walls along the axes 6 and L*, a lowering of the ground level is designed to provide natural lighting to the premises. The height of the premises is 3,0 m from the level of the finished floor to the ceiling. For the arrangement of the pool bowl and the placement of the technical premises of the pool in the axes 1*-6*, A*-Zh*, a technical basement was designed at elevation. -6,600.

Structural and space-planning solutions

The level of responsibility of the building is normal. The building was designed in monolithic reinforced concrete structures according to a frame structural scheme with floor hard disks. The main load-bearing structures of the building are designed to meet fire resistance requirements in accordance with STO 36554501-006-2006. The building is solved without a sedimentary seam between parts of the building of different heights, which is taken into account by the calculation and design of the building's load-bearing elements. The overall stability and rigidity of the building is ensured by the spatial work of vertical, horizontal stiffening diaphragms and structural elements of the frame. The role of vertical stiffening diaphragms is performed by the walls of stair-elevator units with a thickness of 200 mm. Floor slabs serve as horizontal stiffness diaphragms. Columns - section 400x400 mm. The concrete class of the columns at the lower elevations is B40, at the upper elevations - B25. Fittings A400 and A240. The thickness of the floor slabs is 200 mm; 220 mm and 300 mm - the thickness of the slabs above the basement in the areas of exploited coatings. In the floor slabs crossing the outer walls, thermal breaks are provided to prevent freezing. The slabs rest on columns and interior walls. The punching strength of the slabs is ensured by the transverse reinforcement of the slabs and the capitals of the columns with a plan size of 1200x1200 mm and a height of 200 mm. Beams with a section of 400x400 mm are provided along the contour of the ceilings in the places of support of the outer walls and in the places of large openings. Concrete floors and beams B25, reinforcement A400 and A240. The walls of the basement and basement are monolithic reinforced concrete 400 mm thick with insulation. Concrete B25W8F100. fittings A400. Elevator shafts - monolithic reinforced concrete with a wall thickness of 160 mm. The pool bowl is designed in monolithic reinforced concrete and rests on the basement walls. The thickness of the walls of the bowl is 300 mm, the bottom is 300 mm. Concrete grade W8 was adopted as a waterproofing of the walls and slabs of the monolithic pool bowl, all reinforced concrete structures of the pool room are treated with penetrating waterproofing. External walls: load-bearing - from monolithic reinforced concrete; non-bearing - made of bricks 250 mm thick with floor-by-floor support on floors; stained glass windows. Insulation for the outer walls of the building is part of the facade hinged system "ISM - facade", the fastening of which to the supporting structures of the building is developed in the working documentation in accordance with the current technical certificate of the Ministry of Regional Development of the Russian Federation. The supporting structure of the canopy is a rigid reinforced concrete frame, the load from which is transferred to the pile foundation. The canopy cover is formed by a beam system of steel profiles, which rests on a reinforced concrete frame in the middle part and is suspended from above to the columns on steel rods with a cross section of 50 mm. The beams are covered with tempered glass. The visor is designed taking into account the formation of snow bags. Various options for loading with a snow load are considered. Steel C245, concrete B25F150, reinforcement A400. Calculations of building structures were performed using the SCAD software package version 11.3 and analytically using the main regulatory documents. Snow region IV. Wind region II. The foundations are designed on the basis of engineering and geological surveys carried out at the construction site and geotechnical justification for choosing the type of foundations. Foundation design - monolithic reinforced concrete grillages on a pile foundation. Grills for columns - free-standing 700 mm thick, united by a basement floor slab 400 mm thick. Piles - bored with a diameter of 400 mm, length from the bottom of grillages 14,6 m - 17,3 m. Piles are made under the protection of a casing pipe and with excavation. At the base of the piles at an absolute mark of minus 9.40 - dusty sandy loam EGE-10 with a total deformation modulus of 450 kg/cm. The design load on the pile - 120 tons, 110 tons and 105 tons was adopted based on the results of static sounding of soils. Static load tests of piles are provided to confirm the bearing capacity of piles and possible adjustment of the pile field. Material of underground structures - concrete class B25; W6 (piles); F100; fittings of class A400. When calculating the foundation, the load during construction from the installation of a stationary tower crane in the axes "E-D / 3-4" was taken into account. The terrain within the building patch has a significant unevenness, the height difference reaches 4,3 m, which required the construction of a retaining wall. The project provides for two contours of the pit fencing, which ensure the stability of the slopes and protect the pit from groundwater. The design of the outer contour of the fence with a pit depth of 5,8 to 8,3 m - bored tangential piles and steel sheet piles with ground anchors. Ground anchors are made using the technology of injection micropiles, reinforced with a threaded pipe. The calculated load on each anchor is 46 tons. The allowable load will be confirmed by field tests of at least 3 pieces for each type. Bored tangential piles - with a diameter of 400 mm and 620 mm with a embedment length below the bottom of the pit from 4,1 m to 8,1 m. On the top of the pile fence at marks in accordance with the relief, a strapping monolithic reinforced concrete beam 820 mm wide, 600-1000 mm high is made. Steel sheet pile of the outer contour - Larsen L-4 with a embedment length below the bottom of the pit from 4,7 m to 5,7 m. The inner pit is deepened by another 3,45 m in relation to the level of the outer one. The design of the inner contour of the sheet piling is made of steel sheet piling Larsen L-5 and L-4 with a embedment length below the bottom of the pit of 13,6 m. One of the faces of the inner contour is anchored with ground anchors with a design pull-out load of 46 tons.
