Construction method of assembly type prefabricated staircase
The invention discloses a construction method of an assembly type prefabricated staircase, and relates to the technical field of building construction.The construction method comprises the steps that leveling treatment is conducted on the contact face of a beam body and the upper end face of the assembly type prefabricated staircase, material filling is conducted after joint bars are reserved at connection positions, and leveling and sealing treatment is conducted on the top; the top of a cavity between the contact surfaces of the beam body and the assembly type prefabricated staircase is blocked by adopting a PE (Poly Ethylene) rod; the contact position of the beam body and the lower end face of the assembly type prefabricated staircase is subjected to gravel leveling treatment and fixed through fixing nuts, gravel blocking is conducted on the upper portions of the fixing nuts, and a PE rod is put into the top of a cavity between the beam body and the assembly type prefabricated staircase for sealing; the PE bars are added to the two ends of the gap between the side face of the assembly type prefabricated stair and the beam body correspondingly, the position between the two PE bars is filled with the fireproof rock wool, weather-resistant sealing treatment is conducted on the outer sides of the two PE bars correspondingly, the sealing performance of the connecting position is improved, steel bars are prevented from being corroded and damaged, the stair bearing capacity is improved, and collapse is avoided.
本发明公开了装配式预制楼梯的施工方法，涉及建筑施工技术领域，本发明将梁体与装配式预制楼梯的上端面接触面进行找平处理，在预留连接位插筋后进行灌料，顶部进行平整密封处理，且梁体与装配式预制楼梯的接触面之间的空腔顶部采用PE棒封堵；将梁体与装配式预制楼梯的下端面接触位进行砂石找平处理，通过固定螺母进行固定，固定螺母上方进行砂石封堵，在梁体与装配式预制楼梯之间的空腔顶部放入PE棒进行密封；在装配式预制楼梯侧面与梁体之间的缝隙两端分别加入PE棒,两个PE棒之间填充防火岩棉，对两个PE棒外侧分别进行耐候性密封处理，提高连接处的密封性，避免钢筋受到腐蚀损坏，提高楼梯承受力，避免坍塌。
