Description

Technical Field

[0001] The utility model relates to the technical field of stair guardrails, in particular to a novel guardrail structure. Background Art

[0002] Stair guardrails, also known as "stair guardrails", are commonly used protective facilities on stairs in multi-story buildings. Their main function is safety protection. At present, the structure of existing stair guardrails has the following problems: (1) A direct disconnection structure is often used at the turning point of the stairs, which causes the connection between the upper and lower floors to be disconnected, posing a safety hazard. (2) The handrail ends at the disconnected parts of the existing stair guardrails are generally blocked with plugs, which are easy to fall off or be damaged by human beings, increasing maintenance costs. (3) The installation of handrails, guardrails, etc. and columns is mostly carried out by punching. On the one hand, there are high requirements for the punching position on the column. On the other hand, due to the height error between different steps of the stairs, the handrails, guardrails and holes cannot be aligned, resulting in installation difficulties. If forced installation, the handrails, guardrails, etc. will bend, affecting the overall aesthetic effect.

[0003] Therefore, there is an urgent need to provide a new guardrail structure that is safe, beautiful and efficiently installed. Utility Model Content
