Space planning solutions

2.1 Shape and dimensions of the building

The industrial building is a one-story 3-span production building of the production and storage building, in which all the main technological processes are located. Spans are 15 m wide in axes A-B and B-B and 24 m in axes G-D. The height of the columns is 10.8 and 12.6 m. For the mark of the clean floor, elev. + 0.000m .

The maximum height of the building is 17.1 m in the axes G-D. The building has a rectangular plan shape with dimensions in axes A-D - 54 m, in axes 115-84 m .

The building is equipped with lifting transport equipment: one bridge crane with a lifting capacity of 10 and two 5 tons each.

2.1 Compliance with fire safety requirements. Escape routes.

Fire safety is ensured in accordance with the requirements for functional fire hazard buildings F5.1 (see SNiP 210197 item 5.21)

Fire resistance rating of the building - II, structural fire hazard class - C0.

Evacuation of employees is provided through the entrance gate.

Structural solutions of the building

3.1Structural solution of the building

The designed industrial building has a frame structural system. The pitch of the extreme columns is 6 m, the middle columns are 12 m. The spatial rigidity and stability of the building are ensured by the joint work of columns, rafters, crane beams, vertical and horizontal links. Vertical links: crane, located in all spans in axes 34, 3-5, 1112 and 1012; over-crane, located in spans in axes 1012.

3.2 Arrangement of deformation joints

Deformation seam is located in G-B axes to prevent uneven settlement of building.

3.3 Foundations

For the repair shop, the foundations are accepted as prefabricated reinforced concrete columns for individual columns. The depth of laying is 1.800 from the mark of the clean floor and is taken based on the depth of seasonal freezing of the soil. The foundations for the columns in axes 17/A, 1-7/D and 17/G are made of grade FD3135.. The foundations for the columns for the floor are made of grade FA11. Foundations for fuselage columns are made of grade FB21. Heavy concrete of class B12.5 is used for foundations. For reinforcement of foundations hot-rolled reinforcement of periodic profile of class AIII as per GOST 578182 is used.

3.4 Foundation beams

Foundation beams accept the load from wall panels. We apply foundation beams KE0123 series with a section of 250х330.

3.5 Columns

Reinforced concrete columns of continuous section and two-branch columns were used. Snaps the 250mm columns to the axis. Two-branch columns consist of the lower (crane) and upper (crane) parts. Fachwerk columns - solid section column. Columns shall be manufactured in accordance with the requirements of GOST 2368279 and GOST 2311899.

3.6 Crane beams

Steel crane beams are designed in the building. Crane beams 990 mm high are used in spans in axes A-B and D-D. Beams are manufactured in accordance with the requirements (Series 1.426. 2-3). Crane tracks are laid from crane rails in the first span of KR70 type.

Embedded elements are provided in beams. To columns, beams are attached by welding of embedded elements and anchor bolts. Nuts of anchor bolts are welded after alignment of beams. To reduce dynamic effects on beams and reduce noise of moving noise of cranes, elastic gaskets made of rubberized fabric with thickness of 810 mm are laid under rails.

In order to avoid impacts of bridge cranes on the columns of the end frame of the building, steel stops with shock absorbers-buffers made of rubber bars are installed at the ends of the crane tracks, as well as the emergency power outage system of the crane engines.

3.7 Walls

External walls are made of wall sandwichpanels ("KZSK") with polystyrene foam insulation. Based on the heat engineering calculation given below, the outer wall thickness was 50 mm (see paragraph 4.1.). Height of wall panels is adopted 1.2, 1.5 and 1 m, length - 6 m.

Partitions between workshops are accepted with a height of 10 m, made of GVL. Thickness 100mm.

3.8 Bearing structures of the coating

In spans A-B and B-B, the coating is designed from reinforced concrete beams with a slope of 1:12, In span G-D the slope is 1:20.

Trusses are attached to columns by welding of support sheets of trusses with metal embedded parts of columns.

Trusses are provided with embedded parts for installation of lamp trusses, embedded parts for welding to columns, paired angles for attachment of wall panels and embedded parts for attachment of coating plates. Farms are selected according to "Table II.10" [13].

Reinforced concrete trusses of two-pitched lattice with a span of 18 m, a load capacity grade of 3 (m.b. 4,5,6) 1BDR18 - 3 series 1.462.1/80, structure weight 10,4t (for structure with load capacity grade 5 and 6 - 12,1t), height 1640 mm with slope 1:12 (GOST 2021389)

3.9. Roofing enclosures

The coating is made of reinforced concrete slabs 6 m long GOST 2804289. During installation, plates are attached to trusses by welding through embedded parts.

Roof of rolled materials with bitumen impregnation, which includes:

-2 layers of glass cloth with oxidized bitumen 10 mm;

- leveling layer of cement sand mortar with thickness of 25 mm;

- thermal insulation plates made of polystyrene foam, 50 mm thick;

-Gr/B plate 300mm;

The drainage from the coating is accepted as internal. 20 water intake funnels are designed on the coating.

3.10. Communications

In longitudinal direction rigidity is additionally provided by steel links installed in all rows between columns and supports of rafters structures.

Inter-column steel links are located within the height of the crane part of the columns.

Link rods are constructed from paired hot-rolled profiles welded by straps and subassemblies. To embedded elements in reinforced concrete communication articles

are bolted and welded.

3.11. Windows

Window glazing is tape, designed from steel double window panels with aluminum bindings (GOST 2334478). The bindings are assembled from aluminum linings of a box profile with thrust protrusions and corners of staples pressing glass to them. The dimensions of the windows are taken according to the lighting calculation given below (see para. 4.3). In the first and third spans they have a width of 4 m and a height of 4.2 m, the orientation of the light openings is Yu.

3.12. Floors

Floor design in the workshop is as follows:

- compacted soil;

- underlying layer of concrete of class B75with reinforced mesh 60 mm thick;

- waterproofing on bitumen mastic 5 mm thick;

- coating of B15 class concrete with thickness of 100 mm;

- ground concrete on marble crumb 20 mm.

3.13. Gates and doors

External swing gates with a gate are designed in the building with manual opening (series 1.435.917), the size on the facade is 1.2x5m. The passage between the rooms in the workshop is carried out through open doors with dimensions of 3.6x3.6m. The gate canvas consists of 2 flaps. The sash frame, having cassette division, is welded from steel rectangular paired tubular profiles. Carcass cells are filled with fillets made of paired steel sheets, with 6 mm thick insulating material laid between them. Sheets of fillets are made with longitudinal zigs. The filaments are attached to the frame by means of rubber profiles. In one of the flaps there is a wicket.

3.14. Ladders

The building provides fire ladders of the first type - vertical steel with a width of 0.9 m, starting from a height of 1.5 m, and with platforms when entering the roof. From a height of 5 m, stairs are equipped with arcs every 0.7 m. For communication with work platforms inside the building and for emergency exits, open steel service stairs are used in the production building (series 1.459 2). Marsh cosors are made of bent channel. Lower end of kosur has horizontal cut to which support plate is welded. Upper end has vertical cut to which support angle is welded. Welding of marches with transition platforms is performed with the help of final elements.
