Compared with the related art, the utility model has the beneficial effects that:

1. According to the fully assembled stair, the steel beam is additionally arranged to replace the lug of the semi-resting bedplate, so that the wing edges of the prefabricated stair directly fall on the steel beam and do not generate force transmission with the semi-resting bedplate, and therefore the situation that the semi-resting bedplate or the second wing edges possibly have cracks or the components are scrapped due to the impact of the semi-resting bedplate on the second wing edges of the prefabricated wallboard caused by the fact that the wing edges of the semi-resting bedplate are lapped on the lug of the semi-resting bedplate due to the fact that the stair is hoisted when being hoisted on site is avoided;

2. The semi-intermittent bedplate only needs to be provided with two wing edges connected with the prefabricated wallboard, the side edges adjacent to the steel beam are flush edges, the number of special-shaped edges is reduced, the processing difficulty is reduced, and the problem of difficult production in factories is solved.
