Embodiment Construction
[0019] refer to Figure 1-Figure 4 , the present invention proposes a prefabricated staircase of grinding, sliding and shock-absorbing type, which includes a prefabricated stair 1, a fixed platform 2 and a sliding platform 3, one end of the prefabricated stair 1 is connected to the fixed platform 2 through a fixed hinge mechanism and the other end is passed through The milling sliding guide reset mechanism is connected with the sliding platform 3 .
[0020] In the present invention, the prefabricated ladder board is connected with the sliding platform through the milling sliding guide reset mechanism, and the connection structure is realized. During the elastic deformation of the structure under frequent earthquakes, the prefabricated ladder board 1 and the sliding platform 3 do not produce relative displacement, and the connection structure is realized. During the elastic-plastic deformation of the structure under fortification intensity earthquakes and rare earthquakes, the ...
