Description

Technical Field

[0001] The utility model relates to the technical field of building stairs, in particular to a steel structure curved staircase. Background Art

[0002] A staircase is a building component that connects different floors. It consists of a series of steps and related structures and is usually used to provide people with access to and from buildings. Stairs can take many forms, including straight stairs, spiral stairs, and folding stairs. Common materials include concrete, wood, and steel. A steel curved staircase is a staircase designed with a smooth curved shape using steel as the main material. It combines modern architectural aesthetics with structural strength. It has high aesthetics and space utilization flexibility, can achieve large-span design, and ensures safety. It is usually manufactured using prefabrication methods and requires high precision during construction to ensure overall coordination. Steel curved stairs are mostly used in commercial and high-end residential spaces.

[0003] In the design of traditional steel curved staircases, a central pillar is often used as the main load-bearing point, resulting in a lack of support on the outside of the stairs, resulting in insufficient strength and stability. The stairs are prone to shaking due to the shifting center of gravity when walking, which not only affects safety but may also cause discomfort to users. At the same time, the unique resonance characteristics of steel make the stairs prone to generating noise during use, which can easily cause noise pollution to the external environment and affect the user experience.

[0004] Therefore, the utility model provides a steel structure curved staircase to solve the above problems. Utility Model Content
