Description

Technical Field

[0001] The utility model relates to the technical field of stairs, in particular to an assembled staircase flight and a staircase. Background Art

[0002] A staircase is a structure that connects different floors of a building, usually consisting of a series of steps (also called steps) arranged along a certain inclined angle or perpendicular to the ground. The design of the staircase is to provide convenience and safety for people to go up and down floors.

[0003] The main components of a staircase include:

[0004] Steps: Steps are the landing part of a staircase where people step on it. Steps usually have a flat surface to ensure stability and comfort when people walk on it. The height and depth of the steps should comply with relevant building codes and safety standards.

[0005] Handrails: Handrails are located on one or both sides of the stairs, providing support and balance to help walkers stay stable when going up and down the stairs. Handrails are usually made of metal, wood or other materials, and the design should be ergonomic.

[0006] Stair beam: A stair beam is a structure that supports the steps. It is usually located below or on both sides of the steps. It is used to support and fix the various parts of the stairs to ensure the stability and safety of the stairs.

[0007] Stairwell: The stairwell is the vertical space around the staircase that contains the stairs and provides access to upper and lower floors. The design of the stairwell should take into account factors such as fire escape, ventilation and lighting.

[0008] There are many types and forms of stairs, the most common ones include straight stairs, spiral stairs, curved stairs, step stairs, etc. Different types of stairs are suitable for different spaces and design requirements. Choosing the right type of stairs requires considering factors such as building structure, space layout, functional requirements and aesthetics.

[0009] When the existing assembled staircase steps and stairs are in use, the existing assembled staircase is an integral assembled staircase, which is large in size and inconvenient to install and transport. In addition, the staircase installation structure is relatively complex, time-consuming and labor-intensive, which reduces the installation work efficiency and the practicability of the device.

[0010] For this purpose, we propose an assembled staircase flight and staircase. Utility Model Content
