What should be paid attention to in the design of steel structure factory?
Compared with the traditional construction mode, the steel structure workshop has been favored by many enterprises. So, what should be paid attention to in the design of steel structure factory building?
Design description of steel structure factory:
The first thing to be solved in the architectural design of the steel structure workshop is the load-bearing problem. Steel structure factory are subject to building loads, rain, dust, wind, snow loads and maintenance loads. The bearing capacity of the metal sheet is related to the cross-sectional characteristics, strength, thickness and force transmission method of the corrugated metal sheet. Therefore, the design of the factory should pay attention to the bearing capacity of the steel structure.
Structural type of steel building workshop
Corrugated metal layers and cold-formed steel sheets are available for the top panel. For workshops without cranes, the main rigid frame can be a variable-section rigid frame. The beam-type column is of variable section and hinged at the bottom of the column, which is economical and reliable. For factories with cranes, the cross-sectional area of these columns should not be variable, but should be uniform. Moreover, the steel beam can have a variable cross-section, and the column base is rigidly connected, which is safe and economical.
Lighting Design
The huge steel structure factory area, lighting is also a big problem. Especially in some industrial plants, lighting is an essential equipment. Use light panels during the day to improve indoor lighting and save energy. Place light panels or glass in specific locations on the metal roof. A window sill should last as long as a metal roof. The joints between the lighting panel and the metal top panel should be waterproof.
Moisture Proof Design
Summer is the rainy season. To prevent water vapor from flowing out of the metal roof and bottom, the water vapor on the metal roof must be removed. The surface of the metal roof should be filled with insulating cotton, and the bottom plate of the metal roof should be covered with a waterproof membrane. There is a ventilation device on the metal roof, which is used to prevent moisture in the steel structure factory building.
Fire Protection Design
Fire protection issues should be considered in the design of steel construction workshops. When using a steel structure factory, in the event of a fire, the temperature of the steel structure workshop components will exceed the specified temperature, which will reduce the strength and yield strength of the components, and are prone to collapse accidents. For this reason, the steel structure workshop needs to be sprayed with fireproof materials to improve the fire resistance of the building in the fire.
Sound Insulation Design
Noise is an inevitable problem in the production and construction process. Steel construction prevents sound transmission both indoors and outdoors. The top of the metal room is filled with sound insulation material (usually made of sound insulation cotton), and the sound insulation effect is expressed by the difference in sound intensity on both sides of the metal roof. The sound insulation effect depends on the density and thickness of the sound insulation material. Sound insulation materials have different blocking effects for different frequencies of sound, which is worth noting.
Insulation Layer Design
Factories should also pay attention to the insulation of steel structures. If the steel structure factory building is built in a cold area, insulation must be considered in winter. Insulation is achieved by filling with metal roof panels (usually glass wool and rock wool).
Insulation depends on several factors: insulation wool material, density and thickness. The humidity of the insulation cotton, the connection method of the metal roof and the underlying structure (anti-cold bridge). Again using the heat dissipation force of the metal top.
