Architectural and construction solutions

Space planning solutions

The building is designed brick one-story with a basement and attic. The space-planning solution is based on a arceless structural scheme of the building with load-bearing longitudinal-transverse brick walls and slab discs from prefabricated reinforced concrete slabs, providing spatial rigidity and stability of the building.

For conditional elev. 0.000 the level of the top of the clean floor of the first floor is accepted. The average elevation of the ground surface level near the building is 1.200m.

On the ground floor there are living quarters: a hall, two bedrooms, an office, a hall, a kitchen room, a veranda. A garage adjoins the verandah room. The garage is divided into two parts: a warm and cold garage. The level of clean floor in the garage is 1.050 m.

In the basement there are: utility rooms, boiler room, technical underground

The height of the premises of the first floor in the light is 3.0m, the basement - 2.7m, the garage - 2.5m

Power supply

Electric power supply project for a residential building in Orenburg on the street

Krasnogorsk 125 is made in accordance with specification No. 04/3664 from 23.11.05 and permission for the release of power No. 06141415 issued by CES 16.11.05.

According to the degree of ensuring the reliability of electric power supply of a residential building, it belongs to consumers of category III.

The project was developed for 220 V voltage

Pp = 4.9 kW

Ip23,3A

The main consumers of electricity in a residential building are electric lighting, household loads of a socket network, electric drives of a roller turn.

The power supply of the residential building is made from the existing support No. 13 of line VL0.4 kV (parking group) running from TP3032.

The air entry into the house is made with a 0.23 kV line with self-supporting insulated wires (PIS) from support No. 13 and to the introductory distribution panel of the residential building.

Fixation of the PIS to the supports and the house, as well as its connection to the existing VL0.4 kV, is provided using fittings for the PIS manufactured by Taiko Electronics.

At the entrance to the residential building, in the tambour room, the inlet distribution board PR8804312854UKhL3.10V of the recessed version is installed. The board is completed with the VA5735s lead-in switch an independent rastsepitel with rated current of a rastsepitel 50 A, switches on the departing BA6129 lines UZO-DM-4sht. and BA6129 - 8 pieces, the differential relay of leak (DRL) on 100 ma on input and the single-phase electronic counter of the electric power ETs6807P included according to the direct scheme.

The grounding system of the residential electrical equipment is adopted by TNCS.

The project provides for household lighting of the designed premises of the house and outdoor lighting at the entrances to the house. Group lighting networks are powered by PA6129 single-pole switches (In = 63a, Ip = 10 (16) A) installed in the water distribution board of the house.

For outdoor lighting there are light fixtures with filament lamps of type NPB6160, NPB1301 (1302) with degree of environmental protection IP54.

Lighting fixtures with incandescent lamps of type NBB03100 with degree of environmental protection IP64 are provided in the garage and boiler room.

In the auxiliary and technical rooms of the basement there are light fixtures with incandescent lamps of the type NPB6160, NPB1101 (1302) with the degree of environmental protection IP54.

Lighting fixtures with incandescent lamps of type NBO 0760 and NPO 221x60, with degree of protection against the environment IP23, are provided in the rooms of the bathrooms.

In other rooms of the house, household lamps with the degree of environmental protection IP20 are accepted.

The project provides for the following protective measures:

1. Grounding of all non-conductive parts of electrical equipment, which may be energized due to insulation breakdown, by metal connection with zero protective conductor.

2. The project provides for the construction of an artificial grounding device for the electrical installation of the house, consisting of a horizontal grounding conductor along the perimeter of the house, made of strip, galvanized steel 40x4 mm laid at a depth of 0.6 m from the ground surface .

3. The main potential equalization system is introduced into the house by combining the following conducting parts:

- Distribution board RESHINE;

- metal parts of building structures;

- earthing device;

4. Performing an additional potential equalization system by combining the following conductive parts:

- metal duct of lead-in cable;

- bath and boiler housing.

- Distribution board RESHINE.

Connections shall be made with 6 mm2 copper wire PV1.

5. Re-grounding at house entry.

Heating, ventilation and air conditioning

The design takes into account the requirements of SNiP 41012003 "Heating, ventilation and air conditioning."

Heating

Heating of the residential building is provided from the domestic gas heating boiler "Protherm" 40 PLO, installed in combination with the boiler B100MS in the boiler room in the basement of the building. The boiler is equipped with two pumps (for the heating circuit and for the GVA), safety valves with us and a 10-liter expansion tank. In addition, a universal connecting kit "boiler" is required to connect the boiler.
