Description
Technical field
The utility model belongs to building field, suitable for current and access path up and down outside industry, agriculture silo.
Background technology
The outer cat ladder of silo, is usually bent into " several " word shape by reinforcing bar and is embedded in silo wall or is fabricated to the plant of " n " shape in advance
In on silo wall, then weld hand banisters formed it is straight it is upper, directly under passage, this cat ladder can go out during much time using
Existing problems with：
1st, steel bar corrosion, is easily deformed, fractures
2nd, anchoring adhesive aging after for many years, Nian Jie with silo wall insecure, embedded bar loosens, and forms security risk
3rd, when silo height is higher, people has the sense of insecurity of extreme in crawling process straight up and down.
The content of the invention
The utility model aim is to provide a contact band outside a kind of silo from bottom to top, makes one in current and work
Feel safe, comfortable during work, while the passage has the characteristics that durability, applicability.
Silo external spiral formula assembles steel cat ladder, it is characterized in that be twist fixedly connected along silo outer wall around silo periphery,
Including terraced beam, handrail, stent, railing, column, riffled iron pedal, stent is connected and with burying with terraced beam, riffled iron pedal and handrail
Enter the built-in fitting welding in silo wall, handrail is welded with terraced beam, column, railing, and column one end is welded with handrail, the other end and ladder
Beam welds, and riffled iron pedal is welded with both sides ladder beam；The built-in fitting is welded by square steel plate and 4 steel bar ends；Institute
Stent is stated to be welded triangular supports by cross level angle steel, vertical angle steel and bearing diagonal；The handrail crooked radian and silo Curved arc
Spend identical.
The utility model eliminates security risk while meeting to use function, makes one to feel in current and work
It is safe and comfortable, while service life is added, reduce maintenance cost.
