Hoisting scheme of steel structure of a factory building (single-layer light steel structure)
Project name: * * * plant project of the company. 2. Project location: East of North * * * Road, Development Zone, in the original factory yard. 3. Structure type: the plant is a single-layer light steel structure. 4. Building area: the building area of the plant is 8379 m2. 5. Structural design: the seismic fortification intensity is 7 degrees, and the standard freezing depth is 0.85m. The powerhouse foundation adopts reinforced concrete precast pile foundation, with the fourth layer of completely weathered mixed granite in the site soil layer as the pile end bearing layer; The main structure of the plant is light steel structure, and the masonry partition wall is built with MU10 sintered porous bricks and M7.5 mixed mortar. The plant has a total length of 138.5 meters, three spans of 18 meters, 24 meters and 18 meters, and a column spacing of 6.9 meters. The main components include steel columns, steel beams, steel crane beams, steel supports between columns, C-purlins, roof and wall color plates, etc. The plant has 98 steel columns, and the maximum single weight of steel columns is about 1.5 tons. There are 120 crane beams, each of which weighs about 0.85 tons. There are 63 steel roof truss beams, and the maximum single weight of steel roof truss beams is about 2 tons. On the premise of ensuring the construction period, our company is faced with adverse construction factors such as large daily lifting quantities, so safe and civilized construction is particularly important. Our headquarters and project department leaders attach great importance to it, put forward clear requirements for safe construction, and made specific arrangements.
