Architectural and space-planning solutions

Design documentation has been developed for the construction of a medical and rehabilitation center with a boarding house and is divided into two stages of construction. The first stage of construction includes: buildings of type 1 - 3, buildings of section 1 - 16. Buildings of type 1 - 3. Buildings of three types have been developed by project documentation. The buildings are designed with 3 above-ground floors, without a basement and an attic. The principal architectural and planning solutions and the set of premises are the same. The building type 1 consists of two identical 3-storey buildings symmetrically and mirrored relative to the arch connecting them to each other. The building has a rectangular shape in plan. The height of the premises of the first floor is 3,45 m, the height of the premises of the second floor is 3,17 m, the height of the premises of the third floor is 2,82 m. The maximum height of buildings from ground level (-0.40 m) to the top of the parapet is 11,36 m. Building type 2 is designed as a 3-storey building with a square outline in plan. The height of the premises of the first floor is 3,45 m, the height of the premises of the second floor is 3,169 m, the height of the premises of the third floor is 2,82 m.

Section buildings 1-16. The buildings of sections 1-16 form 3 closed quarters of different configurations in plan. Quarter 1 consists of 5 buildings. Quarter 2 consists of 6 buildings. Quarter 3 consists of 5 buildings. Buildings are sectional and include from one to three sections. Each section is designed with 3-4 above-ground floors, without a basement and an attic. The height of the premises of the first floor is 2,68 m, the height of the premises of the second floor is 2,98 m, the height of the premises of the third floor is 2,98 m, the height of the premises of the fourth floor is 3,03 m. The maximum height of the building from ground level (-0.15 m) to the top of the parapet is 13,70 m. On the first floors of each section, the following are designed: the entrance group of premises, premises for service personnel, premises for temporary storage of inventory, luggage and belongings, garbage collection chambers, technical premises. In separate sections, service rooms for vacationers, rooms for a nurse on duty, a box, storerooms for clean and temporary storage of dirty linen, and a room for temporary storage of fluorescent lamps are designed. On the 2nd, 3rd and 4th floors, residential premises are designed - apartment-type rooms. For vertical connection between the floors, each section is provided with an L1-type staircase with access to the ground level, and a passenger-and-freight elevator. The following architectural structures are designed for all buildings. External walls - monolithic reinforced concrete and solid bricks with floor-by-floor support on ceilings, insulated with mineral wool slabs and lined with porcelain tiles according to the "ventilated facade" system. Internal walls - monolithic reinforced concrete. Partitions - brick, aerated concrete blocks, with additional sheathing with plasterboard on a metal frame filled with mineral wool slab. Windows and balcony doors - metal-plastic blocks with double-glazed windows with built-in air inlets. Glazing of balconies and loggias is a stained-glass aluminum structure with single impact-resistant glazing. Doors - metal and wooden, glazed and deaf, fire-resistant and conventional. The roof is flat (low-slope), combined, insulated, with a roof made of rolled materials, exploited terraces - with a top layer of paving slabs. Interior decoration of premises - in accordance with their functional purpose. Finishing of facades: basement, 1st floor - granite slabs on a metal frame filled with facade insulation from mineral wool boards; above-ground floors - porcelain stoneware slabs on a metal frame filled with facade insulation made of mineral wool boards.

Structural and space-planning solutions

Building responsibility level – II, normal. The buildings of sections 1-16 are designed from monolithic reinforced concrete of class B 25 according to a frame structural scheme with stiffness cores formed by the walls of stairwells and elevator shafts. Sections 1, 7, 10 consist of two temperature-shrinkable blocks separated by expansion joints. Columns - monolithic reinforced concrete with a section of 400 x 400 mm, column spacing - 6,0 x 6,0 m.

Fastening of brick walls and a hinged facade system to the supporting structures of the building is provided by flexible connections with anti-corrosion coating. Stair flights and landings are monolithic reinforced concrete. The elevator shafts are monolithic reinforced concrete. Spatial rigidity and stability of the sections is ensured by the joint work of vertical elements connected by floor disks. Buildings of type 1, 2, 3 are designed with a cross-wall structural scheme. External and internal walls are designed with a thickness of 380 mm from solid bricks M 150, F 75 on mortar M 100. External walls - finished according to the ventilated facade system with external insulation with mineral wool boards. Ceilings and roofing - monolithic reinforced concrete 200 mm thick, with the installation of monolithic belts 380 mm high along the load-bearing walls, class B 25 concrete. Stair flights and landings are monolithic reinforced concrete. Spatial rigidity and stability of type 1-3 buildings is provided by a system of longitudinal and transverse walls connected by floor disks. Static calculation of load-bearing structures was performed using the SCAD 11.3 software package. The absolute marks corresponding to the relative mark of 0,000 are individual for each building: in the range from 3.55 to 4.20. The foundations are developed on the basis of engineering and geological surveys. The foundations of sections 1-16 are piled. Piles - prefabricated reinforced concrete driven, section 40 x 40 cm, length 28 m. The maximum design load on the pile is assumed to be 55 tf, which is less than the allowable design load on the pile of 78 tf, obtained from the results of static sounding. The bearing capacity of the piles will be checked by static tests prior to mass immersion, followed by adjustment of the pile field, if necessary. The base of the piles is sandy gray sandy loam (IGE12) with e=0,366, E=140 kgf/cm2, IL=0,20.
