Abstract

The invention provides a steel stair transformation method and a steel stair, and belongs to the technical field of constructions. The steel stair transformation method comprises the following steps that a supporting beam is arranged on an old step plate of an original steel stair; a new step plate is fixedly arranged on the supporting beam, and the tread width of the new step plate is larger than that of the old step plate. According to the steel stair transformation method, the original steel stair does not need to be dismantled, the steel stair is transformed in the mode that the supporting beam is arranged on the step plate of the original steel stair, and the new step plate is arranged on the old step plate and the supporting beam, the requirement for widening the tread of the step plate can be met, and the construction period of transformation construction can be shortened.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a steel staircase transformation method and the steel staircase. Background technique [0002] Steel stairs were widely used in factory buildings before, and with the emergence of many high-tech style buildings, they are also used in many modern buildings. The steel staircase can also be made very simple, with continuous Z-shaped steel plates welded together to form a Z-shaped steel plate staircase, and the folded part is fixed to the wall without any other redundant design. [0003] In the original design of the steel stairs, some treads are designed with a small tread width. When people step on it, the heel is not supported, and it is easy to stand unstable. Therefore, it needs to be modified. During the transformation, if the method of removing the original steel stairs is used, the construction period of the transformation will be longer, which is not conducive to the requ...
