Description

Stair railing with anti-climbing structure

Technical Field

The invention relates to the field of stairs, in particular to a stair handrail with an anti-climbing structure.

Background

Stairways are components of buildings that are used for vertical traffic between floors. The method is used for traffic connection between floors and when the height difference is large. Stairways are also provided in multi-story and high-rise buildings provided with elevators and escalators as the main means of vertical transportation. High-rise buildings, although using elevators as the main vertical transport means, still need to keep staircases for escape in case of fire. The stairs are composed of continuous stair sections (also called stair runs), platforms (rest platforms), enclosing members and the like. The horizontal projection distance between the lowest step and the highest step of the stair is the length of the stair, and the total height of the steps is the height of the stair.

The enclosing component is also called a stair handrail which is a support rod of a stair guardrail. Stair handrails are classified by material: stair macromolecule handrails, stair iron handrails, stair stainless steel handrails, stair glass handrails, stair solid wood handrails, stair copper handrails and the like.

The stair make indispensable partly in modern life as main traffic component in the building, no matter be places such as family, school, market, the setting of stair is visible everywhere, because the stair railing generally is perpendicular setting, and the stair railing height generally is about 1 meter for the stair railing is easily climbed by some children, causes the personal safety hidden danger.
