Portal steel frame steel structure engineering workshop Project overview Project name: Steel structure workshop Project nature: Portal steel structure plant project Project period: 4 months Project introduction The span of the plant is 2*33 meters, the total length of the plant is 270 meters, the building height is 15.500 (the cornice elevation is 13.500 meters), and the roof ridge is set with the usual gas tower, the total construction area is 17,820 square meters. Each span is equipped with 8 intermediate working QD double-beam bridge cranes, based on independent foundation + reinforced concrete floor beam, structural type: Single-layer lightweight portal rigid frame, the roof is made of steel wire mesh + waterproof breathable layer +75 thick glass silk wool +0.5 thick aluminum-zinc plated YX760 molded steel plate, the wall is made of 240 concrete porous brick brick wall below 1.200 meters, and the 50 mm thick polyurethane sealing rockwool composite board above 1.200 meters. 8 doors are installed around the plant, which are 6.5*6.2 industrial sliding doors. Scope of contract (1) Planning and design (2) Construction drawing design (3) General construction contract: civil foundation engineering, secondary structure engineering, steel structure frame, roof panel, wall polyurethane sealing rock wool board, water supply and drainage, fire protection, electrical installation engineering. Demand analysis External wall polyurethane edge sealing rock wool board requires high installation accuracy and good molding effect. solution When installing the outer wall keel, the facade is required to be flat, the polyurethane plate is precisely lofted, and the flatness of the plate installation is precisely controlled to achieve the decoration level installation effect.
Steel structure workshop is a kind of steel structure, steel structure workshop has the characteristics of short construction time, low cost, practical and so on. Because our steel output increases, many have begun to adopt steel structure. Steel structure plant is divided into light and heavy steel structure plant Steel structure factory building is generally a space system composed of roof structure, column, crane beam (or truss), various supports and wall frame. These components can be divided into the following categories according to the role they play 1. Horizontal framing 2. Roof structure 3. Support system (roof part support and support between columns: bearing connection) 4. Crane beam and brake beam (or brake truss) 5. Wall frame
Advantages of steel structure:
1. Wide use: can be used in factories, warehouses, office buildings, stadiums, hangars and so on. It is suitable for single-storey large-span buildings, and can also be used to build multi-storey or high-rise buildings. 2. Simple construction and short construction period: All components are prefabricated in the factory and simply assembled on site, thus greatly shortening the construction period. A building of 6000 square meters can be basically installed in 40 days. 3. Durable and easy to repair: Steel structures designed for general purpose computers are weather-resistant and require minimal maintenance. 4. Beautiful and practical: the lines of steel structure workshop are simple and smooth, with a modern sense. The colorful wall body panel is available in a variety of colors, and the wall can also be made of other materials, so it has more flexibility. 5. Reasonable cost: steel structure light weight, reduce the foundation cost, fast construction speed, can be built and put into production as soon as possible, comprehensive economic benefits are much better than concrete structure building, using steel structure can save 30% steel structure plant cost. The installation process depends on the quality of the steel structure workshop project. Each step of the installation process of the steel structure workshop is strictly controlled, and the next step can only be carried out after the acceptance of each process.
Steel structure plant features: Steel structure plant has the advantages of overall light, saving foundation, less material, low cost, short construction period, large span, safe and reliable, beautiful shape, stable structure and so on. Steel structure plant is widely used in long-span industrial plant, metal and plastic, mechanical equipment, printing paper products, mold and other industries. Warehouse, cold storage, high-rise buildings, office buildings, multi-storey parking and residential construction industry. Note: 1. Pay attention to the positioning of anchor bolts during construction. 2. Repeatedly compound the axis positioning and perpendicularity of each steel column 3. Processing of connection joints between steel column and steel beam or tie rod 4 roof plate installation lap, fixed, etc.
