摘要（英）：

The invention relates to a stair, and particularly discloses a semi-assembly stair with prefabricated steps. The semi-assembly stair comprises a cast-in-situ cantboard and the prefabricated steps, the cast-in-situ cantboard is provided with first embedded bars and first embedded holes, second embedded holes matched with the first embedded bars are formed in the prefabricated steps, the prefabricated steps are provided with second embedded bars matched with the first embedded holes, and a cement mortar layer is formed between the cast-in-situ cantboard and the prefabricated steps in a cast-in-situ mode. The semi-assembly stair with the prefabricated steps is convenient to transport and convenient to install stably, and therefore the problems that an existing prefabricated assembly stair is heavy, difficult to transport, inconvenient to install and instable in installation are solved.
