Separated precast prestressed concrete slab type stairway and production process thereof
The invention relates to the technical field of prefabricated buildings, in particular to a separated precast prestressed concrete slab type stairway and a production process thereof. An existing slabtype stairway is large in dead weight and complicated in production process. The separated precast prestressed concrete slab type stairway comprises a stairway body, wherein the stairway body sequentially comprises an upper platform plate, stair section plates and a lower platform plate from top to bottom; prestressed reinforcing steel bars are arranged on the lower part in the stairway body along the length direction; reserved installation holes and reserved hole reinforcing ribs are respectively arranged on the surfaces of the upper platform plate and the lower platform plate; the stair section plates are provided with hoisting points and demoulding hoisting points; and the prestressed reinforcing steel bars are provided with reserved prestressed reinforcing steel bar plugging slots atreinforcing steel bar outlet holes of flat planels. Compared with a traditional precast stairway, 20 percent of concrete can be saved, 30 percent of reinforcing steel bars can be saved, the dead weight is light, fast production can be realized, and the separated precast prestressed concrete slab type stairway and the production process thereof have a favorable development prospect in the technicalfield of prefabricated buildings.
本发明涉及装配式建筑技术领域，特别是涉及分离式预制预应力混凝土板式楼梯及其生产工艺，现有板式楼梯自重大、生产工艺复杂，分离式预制预应力混凝土板式楼梯，包括楼梯本体，所述楼梯本体自上而下依次包括一体成型的上平台板、梯段板和下平台板，所述楼梯本体内下部沿长度方向布置预应力钢筋，所述上平台板和下平台板表面分别带有预留安装孔并设置预留孔洞加强筋，所述梯段板带有起吊吊点和脱模吊点，所述预应力钢筋在各平面板的出筋孔处设置预留预应力筋封堵槽，比传统预制楼梯节约20%混凝土，节约30%钢筋，自重小，可快速生产，在装配式建筑技术领域具有良好的发展前景。
