Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses prefabricated staircase. Referring to fig. 1 and 2, a prefabricated staircase includes stair body 1, stair body 1 is formed by concrete placement, be equipped with a plurality of strengthening ribs 2 that are parallel to each other along stair body 1's length direction in stair body 1, two rows of distributions about strengthening rib 2 is, be equipped with a plurality of reinforcing plates 3 that are parallel to each other jointly on a plurality of strengthening ribs 2, reinforcing plate 3 and 2 fixed connection of strengthening rib, strengthening rib 2 and reinforcing plate 3 are as stair body 1's skeleton, strengthening rib 2 and reinforcing plate 3 can provide support and fixed effect to the concrete, the effect of reinforcing stair structural strength has been played.

Referring to fig. 1 and 2, the stair body 1 further comprises a plurality of steps 4, a plurality of anti-slip grooves 5 are formed in the top surface of each step 4, and the anti-slip grooves 5 can improve the friction force of the surfaces of the steps 4, so that the possibility that pedestrians slip on the stairs can be reduced. The edges and corners of the step 4 are set to be round corners 6, the round corners 6 can reduce the possibility that pedestrians trip on the stairs, and meanwhile, when the pedestrians fall down, the round corners 6 can reduce the injury degree of the stairs to the pedestrians.
