Steel structure factories are highly favored in the field of construction, mainly because they have advantages over traditional buildings in terms of materials, construction, and enclosure. But more energy also needs to be invested in the design phase. On the basis of making a good overall plan, even small details cannot be ignored.
1. Anti leakage: This is a basic requirement for buildings. To achieve the effect of anti-seepage, it is necessary to use sealing gaskets at the screw mouth and concealed fixing. Seal or weld the overlap of the color steel plate, and if possible, use a full body plate to minimize overlap. Tight waterproof treatment should be carried out at various joints. And it should be highlighted in the steel structure design drawings.
2. Wind resistance: The wind resistance performance of
steel structure factory buildings is related to the fastening force and density of the fixed seats. Designers should ensure that the metal roof panels will not be pulled off by negative wind pressure.
3. Sound insulation: Sound insulation may be one of the concerns of many people about steel structure buildings, but filling the wall layer with sound insulation materials (usually insulation cotton) can solve this problem. Of course, the sound insulation effect is related to the density and thickness of the sound insulation material, which can be selected as needed.
4. Ventilation: To exchange indoor and outdoor air, ventilation openings should be installed on the roof.
5. Moisture prevention: There is usually condensation of water vapor at the bottom and inner layers of the roof, so it is necessary to remove the water vapor inside the roof. The solution is to fill the wall layer with insulation cotton; Lay waterproof film on the floor and design ventilated nodes on the panel.
6. Load bearing: Steel structure factories should consider bearing construction loads, rainwater, snow pressure, and maintenance loads from the beginning of design. Therefore, the load-bearing capacity of the panel, the cross-sectional shape of the panel, the strength and thickness of the material, the force transmission method, and the spacing between the purlins all need to be considered.
7. Lightning protection: Regardless of the height of the building, it is necessary to consider preventing lightning from passing through the metal roof and entering the interior, especially for metal based steel structure buildings.
8. Insulation: The insulation performance of steel structure factories is closely related to the raw materials, density, and thickness of insulation cotton, while also preventing the phenomenon of "cold bridging".
Several details that cannot be ignored in the design of steel structure factory buildings and need to be well planned
9. Lighting: When designing, it is necessary to consider placing lighting panels or glass in specific locations, and to coordinate the service life of the skylight with the metal roof panel. Therefore, waterproofing should be done at the connection between the skylight and the metal panel.
