Description and justification of the external and internal appearance of the object

The object being designed is a three-storey building, carried out according to an individual project. The location of the object is determined by the territory planning project. Dimensions and number of storeys are also taken in accordance with the planning project. In terms of the designed building, it has a shape close to rectangular, with dimensions in the axes of 27,46x49,20 meters. Level of responsibility of the building - 2. Degree of fire resistance - II. The constructive fire hazard class of the building is C0. The number of children attending preschool educational institutions is 160 people. The building of the pre-school educational institution being designed is a three-storey volume with a basement, of complex shape in plan, formed by simple rectangular geometric elements. For the relative mark of ±0.000, the level of the finished floor of the first floor was taken, which corresponds to the absolute mark of +19,85m. The supporting frame of the designed object is a frame-bonded monolithic reinforced concrete frame (columns, stiffening diaphragm, beamless floor slabs). The foundation is a monolithic reinforced concrete slab. The outer walls of the building are non-bearing with the use of the ROCKFACADE thermal insulation system. The inner layer with a thickness of 250 mm is made of: aerated concrete blocks "Aeroc" B2,5D400F50-2 GOST 21520-89, and in wet rooms from ceramic single solid brick KORPO 1NF/100/2,0. sandy mortar M50. On the inside, the brickwork is plastered with a cement-sand mortar with a thickness of -20 mm, and the blocks are rubbed. The ROCKFACADE thermal insulation system consists of: 1. ROCKglue glue for gluing thermal insulation boards; 2. heat-insulating plates FASAD BATTS with a thickness of 150 mm; 3. facade dowel for additional fastening of plates; 4. Base layer: - ROCKmortar reinforcing putty with ROCKfiber fiberglass mesh; -decorative plaster layer using ROCKdecor plaster and ROCKsil paint. The decorative elements of the facade are made by using heat-insulating plates FACADE BATTS with a thickness of 230mm. Socle - cladding with artificial stone Melikonpolar "Polarik" on a metal frame with insulation with PENOPLEX-35 slabs 100 mm thick. Roofing - flat rolled with Technoelast EKP and Uniflex VENT EPV coating with internal (main volume of the building) and external (entrance groups) drains, on a monolithic reinforced concrete floor slab. Thermal insulation of the roof is made using extruded polystyrene foam TECHNONICOL XPS CARBON 30-280 STANDARD wet rooms from a single solid brick KORPO 120NF / 250 / 1 / 100 / GOST 2,0-50 on a cement-sand mortar M530. On the floors, depending on the purpose of the premises: - brick 2007 and 75 mm thick from a single hollow brick KORPu 1NF / 100 / 2,0 / 50 / GOST 530-2007 on a cement-sand mortar M75, and in wet rooms (bathrooms, swimming pool, rooms catering unit) from a single solid brick KORPO 120NF / 250 / 1 / 100 / GOST 2,0-50 on a cement-sand mortar M530. - aerated concrete 2007 mm thick from cellular aerated concrete blocks B75D1F100-2,0 GOST 50-530 on cement-sand solution M2007. Windows and stained-glass windows are made of PVC profiles in accordance with GOST 75-150, filled with double-glazed windows. The principle of a clear division of the building into functional blocks is taken as the basis for the architectural space-planning solution. In the volume of the building, 2-story volumes are clearly visible, with the volumes of the music and gymnasiums located on the 2nd floor, while on the 1st floor of these volumes there is a swimming pool (on the main facade) and a catering unit (on the yard). The basis of the volumetric composition is a 3-storey volume, which has a clear axis in plan with evacuation stairwells strung on it in a straight line, and diagonally incised squares of group cells. The final touch of the solution of the volumetric composition is the inset of two 2-storey volumes of administrative and medical (along the main facade) and diagonally located relative to the main axis with evacuation stairwells - the volume of group cells. Complementary accents of volume are used to solve the entrance groups, which have a simple rectangular shape in plan, but the same volumetric solution of which hides the heterogeneity of the entrance porches themselves. The connection of all premises in the institution on the floors is carried out through the central corridors, passing in the center along the entire building and connecting all its individual parts and elements (group cells, administrative part, catering unit, swimming pool, etc.), from two sides to the central corridors adjoining volumes of evacuation stairwells, which also connect entrance groups and group cells. The volumes of the stairwells protrude at the ends of the building and rise above the roof, thus organizing exits to the roof for the purpose of its maintenance. In the basement of the building there are: an ITP room, a ventilation chamber and an air intake compartment with it, a water metering unit, a carpentry workshop, a room for garden tools, a room for temporary storage of fluorescent lamps, a dressing room with a shower room and a bathroom, a technical room for a pool.
