Nowadays, more and more people use steel structure to build factory buildings. At present, steel structure factory buildings are also the most advantageous building structures. What problems should we pay attention to when designing steel structure factory buildings? Let's share it with you today.
1. Load Bearing
Steel structure workshop is under construction load, rainwater, dust, snow pressure and maintenance load. The load-bearing performance of metal roof panel is related to the section characteristics of the plate, the strength and thickness of the material, the mode of force transmission and the spacing of purlin (sub purlin).
2. Daylighting
The building area of steel structure factory building is generally relatively large. The indoor lighting can be improved by skylights in daytime to save energy. In order to arrange daylighting panels or glasses in specific positions of metal roofs, the service life of skylights should be coordinated with metal roofs, and waterproofing treatment should be done at the joint of skylights and metal roofs.
3. Moisture-proof
Especially in the rainy summer season, to prevent condensation of water vapor in the metal roof floor and the metal roof layer, and to drain away the water vapor in the metal roof layer. The solution is to fill the metal roof with insulating cotton, lay waterproof film on the metal roof floor, and have ventilated joints on the metal roof panel.
4. Lightning protection
Summer thunderstorm, steel structure factory building design, need to lead lightning to the ground, to prevent lightning breakdown metal roof into the indoor.
5. Fire prevention
Fire is a hidden danger in the use of steel structure factory building. The metal roofing material will not burn and the flame will not penetrate the metal roofing when the fire happens in the steel structure workshop.
6. Impermeability
In addition to doing a good job of leak prevention, steel plant must also prevent rainwater from seeping into the metal roof panel from the outside. Rainwater enters the metal roof mainly through overlapping cracks or joints. To achieve anti-seepage function, it is necessary to use concealed fixing after sealing gasket is used at the screw mouth, sealant or welding is used at the overlap of the plate, preferably long plate to eliminate overlap, and waterproof treatment with tight abdominal distension at various joints.
7. Sound insulation
Generally speaking, steel structure workshop is mostly used in production workshop. In the process of production and construction, there will inevitably be noise. In order to prevent sound from spreading from outdoor to indoor or from indoor to outdoor, steel structure factory building will inevitably produce noise. Sound insulation material is filled in the metal roof layer (usually made of insulating cotton). The sound insulation effect is expressed by the difference of sound intensity on both sides of the metal roof layer. The sound insulation effect is related to the density and thickness of the sound insulation material. Attention should be paid to the fact that sound insulation materials have different effects on different frequencies of sound.
8. Thermal insulation
Do a good job of rainwater in summer, on the other hand, do a good job of winter temperature preservation. Prevent heat transfer on both sides of metal roof of Changzhou steel structure factory building, and make indoor temperature stable. The thermal insulation function is realized by filling the thermal insulation material (glass wool, rock wool) under the metal roof panel. The thermal insulation effect is expressed in U value in W/M2K. Thermal insulation performance is determined by the following factors: raw material, density and thickness of thermal insulation cotton; humidity of thermal insulation cotton, connection mode between metal roof panel and underlying structure (to prevent "cold bridge" phenomenon); thermal radiation repeatability of metal roof.
