High-strength prefabricated concrete stair and manufacturing process
The invention discloses a high-strength prefabricated concrete stair and a manufacturing process, and the manufacturing process comprises the following steps: step 1, placing a manufactured reinforcement cage into a built wood mold body, and pouring cement; secondly, the wood mold body is dismantled, the solidified stair step treads are ground to be flat, and the whole building body is subjected to film covering maintenance; and thirdly, a channel with the same shape as the bent part of the top of the connecting rib is cut in the back face of the pedal, inserting is conducted along the exposed connecting rib through the channel, and cement casting is conducted on the channel after inserting is conducted. The stair further comprises a stair body, a side blocking body is arranged on the side face of the stair body, an integrated reinforcement cage is arranged in the stair body and the side blocking body, and a pressure-bearing rib body is arranged on the portion, located on the step, of the reinforcement cage. A plurality of reinforcement cages in the stair can be built in advance and are respectively poured in the wooden mold body, so that the stair does not need to be built layer by layer, and the built stair can be directly spliced and fixed for use.
本发明公开了一种高强度预制混凝土楼梯及制造工艺，包括步骤一：将制作好的钢筋笼置入搭建好的木质模体内，并且浇灌水泥；步骤二：拆除木质模体，将凝固的楼梯台阶踏面进行打磨平整，并对整个楼体进行覆膜养护；步骤三：将踏板的背面割出与连接筋顶部折弯部分相同形状的槽道，通过槽道沿着裸露在外的连接筋插入，插入后对槽道进行水泥浇铸。还包括楼梯本体，所述楼梯本体的侧面设置有侧挡体，所述楼梯本体和侧挡体的内部设置有一体的钢筋笼，所述钢筋笼位于台阶部分设置有承压筋体。本发明可以将楼梯内的钢筋笼事先搭建好多个，并分别在木质模体内进行浇灌，这样就不需要一层一层的建造，可以将建造好的楼梯直接拼接固定使用。
