production building 12 x 42m

Structural and space-planning solutions KM grade working drawings are used for development of KMD grade drawings. If necessary, deviations from KM grade drawings shall be agreed with the design organization. Designed building - production, dimensions of the building in axes 12.0 x 42.0m, extension 6.0x12.0m. The height of the building is 7.5 m. For relative elevation 0.000 the level of clean floor Structural solution of the frame is adopted. The building is a metal frame of a frame-coupling scheme. The connection of trusses and columns is hinged. Connection of columns to the foundation is rigid in the plane of the frame, hinged from the plane of the frame. General stability of the building is ensured by rigid conjugation of columns with foundations in the plane of the frame, vertical connections along columns from the plane of frames, horizontal connections along the coating. Stability of trusses is provided by system of horizontal and vertical connections on coating. Enclosing structures - wall sandwich panels with a thickness of 150mm, roof sandwich panels with a thickness of 200mm. Roofing sandwich panels for addition in axes 6-8/B-B shall have bearing capacity of not less than 540kgf/m2 with two-span diagram (2 spans of 2.8m). The layout of curtain panels is horizontal. Fachwerk is provided to secure wall panels, windows, doors, gates. For access to road transport in the building there are gates in axes 6-7 along axis A. Sectional gates, Alutech companies. The dimensions of the opening in the light are 3.5x3.5m. The actual dimensions of the gate canvas should be clarified during measurements after installation of the fachwerk structures. Loads on metal structures. Design value of wind load 32.2kgf/m2 (taking into account Cx coefficients according to SNiP "Loads and impacts") Design value of snow load 180.0 kgf/m2 Design load on the floor in axes 1-3/A-B is 480kgf/m2 taking into account bracing weight with thickness not more than 40mm. If actual loads differ from those accepted in the design, the change shall be agreed with the design organization Materials and joints of metal structure elements Structure material - steel as per GOST 27772-88, S255 for truss belts, S245 for other structures. Factory welded joints - semi-automatic welding in carbon dioxide (according to GOST 8050-85), welding wire grade Sv-08G2S. Welded and bolted mounting joints. To carry out weld assembly joints manual arc welding by E42A electrodes in accordance with GOST 9467-75*. Accept unspecified welds during development of CMD set. Bolted connections - on bolts of accuracy class "B," strength class 5.8. Automatic steel shall not be used. Minimum force for fixation of elements - 5.0tf Fabrication and installation of metal structures Assembly of trusses and their individual parts shall be carried out at the manufacturer in rigid conductors. Possible gaps between trusses and column heads shall be filled at installation with gaskets to be supplied complete with trusses Temporary connections shall be used at installation to ensure stability of structures. All structures of closed profiles shall be sealed. It is necessary to provide caps from t4 C245 steel in faces of profiles the Size of a preliminary inhaling for base bolts of columns of K1 - not less than 4.5 CU, for racks a fakhverka of Sf2, Sf3 - not less than 2.0 CU the Bases under columns - column, sole width 1.2kh1.8m and 0.9kh1.5m, from B15 F75 W4 concrete. Concrete preparation from concrete B7.5 100mm thick shall be performed under the foundation base. Foundation beams are monolithic, concrete B15 F75 W4. Installation of foundation beams shall be carried out after installation of frame columns and vertical links along the columns. Lay a 50 mm layer of foam (or similar material) under the bottom of the foundation beams.
