Structural solution of the building

1.5.1 Foundations

The project adopted prefabricated reinforced concrete columnar foundations. The foundations in the plan have a square shape. The height of the steps of the plate part is 500 mm. Foundations shall be installed on 100 mm thick concrete preparation. The cutting of the foundation is located 2300 mm below the level of the clean floor. Foundations are reinforced with reinforcement grids (horizontal element) and flat frames (vertical element). Grids and flat frames are made from reinforcement of periodic profile using contact point electric welding at all points of rod intersections.

The project also adopted monolithic reinforced concrete walls of the technical underground. Rods Ø10 mm made of hot-rolled steel of periodic profile of class AIII, located with pitch of 320 mm, are used as working reinforcement of retaining walls. Concrete class of monolithic reinforced concrete retaining walls - B15.

Depth of laying of the base: Nz = the NPR + To = 1.8 + 0.2 = 2.0 m. The vertical waterproofing of the bases is made by means of a plastering of a side surface by bituminous mastic. Horizontal waterproofing is carried out using 2 layers of ruberoid.

1.5.2 Columns

Cast-in-situ reinforced concrete frame columns. They have a square section. The section size of the columns is 400x400 mm. Columns are reinforced by knitted frames. Working valves made of hot-rolled steel of periodic profile of class AIII. Number of reinforcement bars - 4 pcs, diameter - Ø 25 mm. Concrete class of frame columns - B15. To bind the reinforcement frame of columns, Bp1 class knitting wire is used.

1.5.3 Flooring

The floors of the building are reinforced concrete monolithic beam-free, 220 mm thick. As lower working reinforcement, grids are used, with 200x200mm cell, with longitudinal and transverse rods Ø14 made of hot-rolled reinforcement steel of periodic profile of class AIII. As the upper working reinforcement in places of overlap and columns conjugation, grids are used, with 200x200mm cell, with longitudinal and transverse rods Ø14 from hot-rolled reinforcement steel of periodic profile of class AIII. Floor concrete class - B15. To tie the reinforcement frame of the slab, Bp1 class knitting wire is used.

1.5.4 Stairs

Stairs are used to connect the floors of the building. The project adopted prefabricated reinforced concrete stairs. Such stairs are made in the form of solid reinforced concrete elements. The staircase consists of marches and platforms. The slope of the marches is adopted 300mm with a tread size of 300 mm and a riser of 150 mm. The width of the marches is 1350 mm, and the height of the rise is 1500 mm. Number of steps 11. A 100 mm clearance shall be provided between the march to allow passage of fire hoses. For safety and ease of movement, stairways and platforms are equipped with fences with handrails 0.9 m high.

1.5.5 Wall fence

The wall enclosure is multi-layered and consists of: facing brick of ceramic full-white on M75 grade solution, insulation from PVC foam on adhesive composition for priming and ordinary clay brick of semi-dry pressing of M75 grade on M50 solution.

The wall fence on the inside is plastered with M100 grade solution. The thickness of the plaster is 0.035 mm. External walls are reinforced by a grid with a cell 200kh200mm (longitudinal cores from Ø4 Vr1, cross of Ø8A1), through 2 rows of a brick (400 mm).

1.5.6 Partitions

Inter-apartment partitions are made of foam concrete blocks 200 mm thick; in bathrooms and bathroom: brick from ordinary clay brick semi-dry pressing brand M75 on solution brand M50; intra-apartment: gypsum board b = 80mm, with laid roll mineral wool sound insulation.

1.5.8 Windows

The light openings have the appearance of separate windows. They are used for natural lighting and space ventilation. The filling of window openings is double. The structures for filling the window openings of the building are made of wood. They consist of boxes with swing bindings or door canvases hung in them on hinges. Sashes of window bindings are framed by bindings. Glass with thickness of 3-4 mm is installed in folds (slots) of bandages. On perimeter glass fastens the shpatika (which are pro-thinned out by laths of 16х10 mm2) with elastic laying (putty, frost-resistant rubber). The binding flaps open inside the rooms. Aeration of rooms is performed through opening windows and doors of bindings.

1.5.9 Doors

The project adopted wooden deaf canvases. The door consists of a box and flap webs opening to one or two (swinging webs) sides. A door encloses an opening that links spaces. The thickness of the door webs is 3053 mm. According to the position in the building, the doors are divided into entrance to the building; tambourine; inter-room; in bathrooms; office, forming passages to office premises - attics, basements, roofs, etc. The direction of opening doors is determined by the unimpeded evacuation of people from the premises. Glass of 4 mm thickness is used for glazing of webs. Glass slots are framed with wooden layouts and sealed with gaskets made of conventional or frost-resistant rubber. Door webs 2 m high are hung on two hinges. Locks and door handles are installed at a height of 1 m from the floor level. U-shaped door boxes without a threshold for inter-room doors are expanded from below by a mounting board removed at the installation site. Entrance door webs are hung in the box by means of three hinges - two at the top and one at the bottom.

Engineering equipment of the building

Domestic sewerage system. Hot water supply is central. Water is supplied to bathrooms and kitchen rooms.

Lighting in the project is accepted as luminescent, as well as daylight lamps.

For heating a residential building, a water heating system is provided with local heating devices - aluminum radiators from pipes from the city network.

Power equipment - from local voltage networks 380/220 V.

The project provides for administrative and economic communication.

Ventilation - plenum-exhaust through the provided ventilation shafts.

To remove precipitation from the roof, an external organized watershed is provided. For this, gutters are located on the roof, and gutters with drains and hinged gutters are made along the perimeter of the building.

Description of decisions taken

The construction master plan was developed for the period of construction of the rafter roof. The general plan is acquired with open warehouses.

Construction plot plan - a drawing of the construction site, which shows the designed building, temporary roads, warehouses, mechanisms, household premises, engineering communications and fences.

The design of the construction master plan is based on the following principles:

1. Site Management

2. Compliance of site solutions with building construction technology as reflected in the planning schedule

3. Interconnection and placement of machines, warehouses, networks, roads and temporary buildings

4. Compliance with health and safety regulations

5. Provision of cultural and consumer services for workers

6. Minimum Temporary Construction Costs

Design sequence.

1. Calculation of requirements for temporary buildings and structures

2. Calculation of areas and warehouses

3. Calculation of water and electricity demand

4. Graphic representation of the construction master plan

5. Determination of techno-economic indicators

6. Construction plot plan built on a scale

7. Road width accepted 6 m

8. The radius of turn of roads is 12 m

9. The distance between fire hydrants is 150 m. The distance of hydrants from the road is 2 m. Fire hydrants are outside the danger zone.
