Humidity zone: normal

Design air temperature of the coldest five days: 280С,

Average heating temperature: - 4.40C,

The heating period is 217 days.

2. Space-planning and structural solution of the workshop.

The design of the 4-storey building of the loading unit was developed according to the given planning scheme from unified reinforced concrete elements of factory manufacture .

The reloading unit with mechanized sampling is intended for binding as part of the complex of the newly under construction gravel plant, as well as as an independent structure during the reconstruction or expansion of the existing enterprise. The following process operations are performed in the transshipment unit:

- Overloading of finished products (crushed stone of fractions from 5 to 10, from 10 to 20 and from 20 to 40 mm) coming from the main body to conveyors distributing it to the corresponding warehouses of finished products

- transshipment of finished products coming from crushed stone warehouses to conveyors directing it to the loading unit for railway transport,

- mechanized extraction of crushed stone and its gravity supply to the laboratory.

Crushed sand enriched from crushing screenings passes through the transfer unit in transit to the sand storage.

Mechanized sampling is carried out by means of bucket samplers PC18 installed on the overload from the conveyor to the conveyor. Partial samples are taken from the crushed stone stream of each fraction, reduced by gravity through pipes and entered into sample containers found in the laboratory. The main operating mode of the samplers is automatic cycling. The time interval between cycles is 30 minutes.

The laboratory carries out daily and periodic tests of finished products, as well as periodic testing of intermediate products of mining mass processing. The laboratory is equipped with a set of test equipment in accordance with the requirements of GOST 826976 and GOST 873575.

The mode of operation of the transshipment node is year-round, 260 working days a year in the shift 3 of 8 hours. For conveyors transporting crushed stone from under the warehouses to the transshipment unit, the operating mode is year-round 365 days a year in the shift 3 of 8 hours, the equipment working time utilization factor is 0.85, the annual fund of the equipment net working time is 5300 hours.

Repair works are carried out using a crane of suspended electric single-unit lifting capacity of 2 tons, as well as manual hoists.

The electric drives of the reloading unit are controlled in three control modes: centralized automated, local interlocked and local.

The reloading unit is equipped with plenum ventilation, aspiration units. Water supply of fresh production, recycled production and domestic water is provided, as well as removal of industrial and domestic effluents.

Technological processes are carried out under normal temperature and humidity conditions. The fire resistance of the building is the second.

The frame of the workshop building with a coating of flat elements consists of transverse frames formed by columns jammed in the foundation and hinged rafter trusses resting on them.

Foundations for columns of reinforced concrete glass type. Foundations - monolithic, reinforced concrete. Concrete B15 is used. The foundation is accepted according to GOST 2402280. Bottom laying depth is accepted below ground freezing level

Foundation beams - precast reinforced concrete according to the 1.4151 series. Installed under external walls, 400 mm high. They have a taurus section. Beams are designed for load from solid walls and walls with window and door openings located above the middle of the foundation beam. There are tides (concrete columns) to rest on the foundation. The width of the tides is 300 mm.

The project used precast reinforced concrete columns according to the 1.42012 series.

Rafters cover the span and, like rafters, directly support the roof flooring. According to the scheme of perception of external and distribution of internal forces in an industrial building, we use a bevel-free truss with a circular outline according to the 1.4633 series .

Coating slabs are used according to the series 1.442.1-1 prefabricated reinforced concrete. The coating was decided using ribbed plates with a length of 6 m and a width of 3 m, they are equipped with longitudinal ribs with a height of 0.25 m. The end transverse ribs of the plates are equipped with inlets that provide stiffness of the contour. Plates are reinforced by stressed reinforcement located in ribs and shelf. During installation, plates are welded in at least three points to rafters. The seams between them are filled with 200 grade concrete on fine aggregate. The water drain is internal, the number of funnels is taken in accordance with the recommendations. The roof of the building is rolled from four layers of ruberoid with insulation (polystyrene foam PSBS, expanded clay gravel).

For external walls, two-layer panels of light concrete according to the series 1.832.1-9 are used. Panels are divided into ordinary, angular, basement, reinforced to perceive wind load from window fills. Thickness of panels is 400 mm. The weight of the mounting element is 7.5 tons. The basement panels are supported by foundation beams. Panels are painted with polymer paint of light tones.

Internal partitions are made of asbestos-cement extrusion panels according to the series 1.000.8-1. The walls are finished with plaster, oil and water emulsion paints, EP enamel - 51 are used for painting. Glazed tiles are used for facing.

Windows are used steel in the 1.436.217 series. Stairs - prefabricated reinforced concrete in the series 1.050.12, and steel in the series 1.450.3-3.

Steel gates are used in the 1.435.917 series, for a transformer substation - individual. Wooden doors according to GOST 2469881, GOST 1462484, GOST 662974.

The roof is rolled, four-layer on bitumen mastic.

In the building there are concrete, mosaic floors made of linoleum.

3. Space-planning and structural solution of ABK

The space planning solution is based on a functional diagram. The administrative and household building includes sanitary facilities; Support and administrative premises.

The ABK building consists of two floors .

ABK has a frame structure of unified reinforced concrete columns. The floor level of the first floor corresponds to the floor level of the workshop. Prefabricated reinforced concrete columns are adopted with a section of 300x300 mm, a T-section girder with a height of 400 mm. Slab slabs are ribbed 420 mm thick. External walls of double-layer reinforced concrete panels.

Stairs of frame structure from prefabricated marches and platforms resting on girders fixed on columns. Partitions made of gypsum concrete panels, and in wet rooms made of reinforced concrete slabs. The coating is combined, the roof is rolled, the drainage is internal.

3.2. Defining Auxiliary Spaces

In addition to domestic premises, support rooms are also provided:

Medical center - S = 12 m2 - with a list of 50 to 150 employees.

Dining room. The number of places in the dining room should be taken at the rate of one place per four shift workers - 6 places. The area of ​ ​ the eating room should be determined at the rate of 1 m2 for each visitor, but not less than 12 m2. Dining area S = 12 m2;

3.3. Administrative premises

The office of engineering and technical personnel is accepted at the rate of 6 m2 per one employee of the design bureau. Cabinet area - 24 m2;

The area of ​ ​ the labor protection cabinet is determined depending on the list of employees at the enterprise: up to 1000 people. - 24 m2;

Office of the shop manager. The area shall not exceed 15% of the total area of the working premises. S = 8 m2;

4. Thermal calculation of the coating

Thermal engineering calculation is performed according to SNiP "Thermal protection of buildings" and SNiP "Thermal protection design of buildings."
