There will be a certain slope in the construction of the factory building to avoid rainwater deposition. The same is true for steel structure workshop. A certain slope should be selected during construction to avoid rainwater corrosion. So what should be followed in the selection of roof slope during the fabrication and installation of steel structure workshop? The specific method is as follows:
1. For the sloping roof of the light steel structure factory building, when the steel structure is manufactured and installed, the slope is between 1/8 and 1/20, that is, the minimum slope can reach 5%. Generally, the slope of the roof is designed according to the projected area of the slope roof and the local rainfall.
2. The slope of the general steel structure worskhop roof is between 1-3%, that is, if your color steel roof is 100 meters long, the height difference of the roof will be 1-3 meters. The specific operation needs to be adjusted according to the actual situation, but it should not exceed 5%. The drainage capacity of color steel plate with groove is definitely stronger than that of flat plate. In the process of steel structure construction, it is necessary to pay attention to the joints between the boards and the joints between the boards and the walls. The most commonly used is to apply structural glue (for glass curtain walls), and there are nail holes. Workers will use self-tapping nails or drill tail nails to fix the color steel plate on the steel frame. This place is also a leak point, which must be nailed Structural glue is also applied around the eyes. Generally, there will be no problems after treatment. The hidden danger is to prevent extreme weather, strong wind, heavy hail, etc., because the strength of the color steel plate is not very good, and it will rust after a long time.
3. The roof slope of a single-story industrial steel structure factory building is generally 1/10. There is no specification for large slopes in the fabrication and installation of steel structures. The rainfall is not very concentrated, with a slope of 20%, the roof truss is high, the roof truss and supports consume a lot of steel, and it attracts wind loads.
