A component used as a vertical traffic between floors in a building. Used for transportation between floors and when the height difference is large. Stairs are also required in multi-storey and high-rise buildings with elevators and escalators as the main vertical means of transportation. Although high-rise buildings use elevators as the main vertical means of transportation, they still have to keep stairs for fire escape.
The staircase consists of a continuous step (also called a ladder run), a platform (resting platform) and a retaining member. The horizontal projection distance between the lowest and highest step of the stairs is the ladder length, and the total height of the steps is the ladder height. Stairs have been engraved in the image of heavy houses on bronze wares during the Warring States Period. In Italy from the 15th to the 16th centuries, the interior staircase was liberated from the traditional enclosed space, making it a part of the architecturally rich and decorative building.
A snap ring (a portmanteau of "circle" and "clip"), also known as a C-clip, Rotor Clip, circlip or Jesus clip, is a type of fastener or retaining ring consisting of a semi-flexible metal ring with open ends which can be snapped into place, into a machined groove on a dowel pin or other part to permit rotation but to prevent lateral movement. There are two basic types: internal and external, referring to whether they are fitted into a bore or over a Shaft. Circlips are often used to secure pinned connections.
