Prefabricated combined stair
The invention discloses a prefabricated combined stair. The stair comprises multiple stair steps, the cross section of each stair step comprises a step face side, a lower bottom side and two side edges arranged vertically, the prefabricated combined stair further comprises a stair step groove part, the front face of the stair step groove part is concaved downwards to form a groove, and the stair steps are inserted into the groove to be sequentially extruded and overlapped upwards along the bottom face of the groove in an inclined mode to form a step body. Through the combination of the prefabricated stair steps and the stair step groove part, self-weight extrusion of the stair steps enables the stair steps to be limited inside the groove in the stair step groove part, assembling is quite convenient, and the manufacturing cost is low; meanwhile, the requirement for structural strength of the stair steps is low, in this way, the stair steps can be directly made of light materials, and then the self weight of the whole stair can be greatly reduced.
