Detailed Description

The following detailed description of the utility model is provided in connection with the accompanying drawings to facilitate understanding and grasping of the technical scheme of the utility model.

Referring to fig. 1, a prefabricated assembled stairway comprises a ramp frame 1, treads 2 and landings 3 provided at both ends of the ramp frame 1, respectively. The both ends of inclined ladder frame 1 are provided with connecting plate 5, are provided with recess 31 on the landing 3, and connecting plate 5 and recess 31 adaptation, recess 31 are spacing to connecting plate 5, and for the connection of convenient connecting plate 5 and landing 3, connecting plate 5 is provided with third through-hole 51 towards landing 3, and recess 31 is provided with connecting piece 32 towards connecting plate 5, third through-hole 51 and connecting piece 32 adaptation. The finished prefabricated staircase can be realized by simply assembling the inclined ladder frame 1, the pedals 2 and the stair platform 3, so that the operation is simple and convenient, and the difficulty of a tower crane is reduced.

Referring to fig. 2, the ramp 1 comprises two symmetrical mounting brackets 11; the two symmetrical mounting brackets 11 can enhance the stability and strength of the ramp 1. A plurality of mounting grooves 12 are uniformly formed in the opposite sides of the two mounting frames 11 along the length direction, and the pedals 2 are arranged in the mounting grooves 12; the mounting groove 12 performs a limiting function on the pedal 2. In order to fix the pedal 2 and the inclined ladder frame 1, a fixing piece 4 is further arranged, the fixing piece 4 is made of first reinforcing steel bars, the integral strength of the prefabricated staircase can be enhanced, and the bearing capacity of the staircase to a human body is improved.
