In the high-rise steel structure building, stairs are the most important part, so how to choose stairs in the steel structure?
Classification of stairs
In light steel structure, the staircase forms commonly used are straight staircase and ramp staircase.
Straight ladder
In general, stairs are not often up and down or can not be set up because of site constraints when the use of ramps, mostly repair stairs. Outdoor staircases in steel structure factory buildings are usually straight staircases with a width of 600-700 mm. Angle steel is commonly used in vertical poles and other stressed members.
Inclined ladder
Stairs are generally composed of staircase beams, pedals, platform beams and platforms. The section of staircase beams is usually made of channel steel, I-beam or steel plate; the section of platform beams is usually made of channel steel or I-beam; the materials used for pedal are pattern steel plate, glass, wood and composite pedal composed of concrete and steel plate; and the platform plates are mostly made of concrete floor plate and pattern steel plate.
Characteristics of Steel Stairs
1. Small area.
2. Beautiful shape. Steel stairs have various shapes, such as U-shaped corner, 90-degree right angle, S-shaped 360-degree spiral, 180-degree spiral, and various shapes are also very beautiful.
3. Strong practicability. Cast steel pipe is often used in steel structure, including seamless steel pipe, flat steel and other steel skeletons.
4. Bright color. The surface treatment technology of steel stairs is varied. It can be either fully automatic electrostatic powder spraying or full galvanized or baked paint. The treated stairs are beautiful in appearance and durable. Suitable for indoor or outdoor use in most occasions.
If the surface treatment technology of steel staircase is good, it can fully reflect the modern steel construction art, and it is also a kind of aesthetic feeling.
