Further, the surface of the handrail round bar is fixed with Anti-slip cover by way of gluing, the Anti-slip cover it is outer
Surface is provided with several protrusions, and the protrusion is hemispherical.
By using above-mentioned technical proposal, Anti-slip cover is made using rubber material, compared with the handrail round bar made of the metal
With bigger frictional resistance, while by setting protrusion, the frictional resistance on Anti-slip cover surface is further increased, work people is reduced
The case where member has skidded when holding handrail round bar.
Further, Luminous belt in a ring is provided on the Anti-slip cover.
By using above-mentioned technical proposal, when working at night personnel's stairs, staff's identification is facilitated to help
The position of hand round bar.
Further, it is provided with pairs of hook on the handrail round bar, is provided with protective net between the handrail round bar,
The two sides of the protective net are provided with the lantern ring being cooperatively connected with hook.
By using above-mentioned technical proposal, it is fixedly connected with protective net with the mode that lantern ring cooperates using hook, protects host
It is used to prevent staff from the accident slid occurring, further increases the security performance of entire stair.
Further, the column being evenly arranged in the fixed beam for fixing handrail round bar is several, the column
One end is provided with the mounting plate to offset with fixed beam, and fixing bolt is provided on the mounting plate, and the fixing bolt will
Mounting plate is threadedly coupled with fixed beam.
By using above-mentioned technical proposal, column is mainly used for fixed handrail round bar, and firm using being threadedly coupled
It is fixed in fixed beam, while also easy to disassemble when later maintenance.
Further, the column is provided with several connectors, the connector setting spherical in shape, and the handrail round bar is worn
Cross connector.
By using above-mentioned technical proposal, connector is reinforced handrail round bar and is stood mainly for fixed handrail round bar
The structural strength of column junction.
In conclusion the utility model has the following beneficial effects:
1. passing through the setting of non-slipping block and anti-skid chequer, stairs antiskid ability is further increased, staff is reduced and foot occurs
A possibility that lower skidding；
2. passing through the setting of handrail round bar and Anti-slip cover, staff is avoided to hold the case where handrail round bar has skidded.
