Novel assembly type prestressed concrete pipe pile column joint and manufacturing method
The invention discloses a novel assembly type prestressed concrete pipe pile column joint and a manufacturing method. The novel assembly type prestressed concrete pipe pile column joint comprises an upper assembly type prestressed concrete pipe pile, a lower assembly type prestressed concrete pipe pile, a steel reinforcement framework and a core steel pipe. The steel reinforcement framework is a whole and comprises upper and lower assembly type prestressed concrete pipe pile column reinforcements, beam reinforcements and joint core area reinforcements, and the upper and lower assembly type prestressed concrete pipe pile column reinforcements comprise pipe pile column longitudinal reinforcements and pipe pile column stirrups; the joint core area reinforcing bars comprise joint hoops composed of core steel pipes, longitudinal bars and dense stirrups, and the beam reinforcing bars comprise beam longitudinal bars and beam stirrups. The part of the node core area of the beam longitudinal bar is subjected to bending treatment and can tightly wrap the core steel pipe of the node core area, and the core steel pipe is prevented from falling off. The core steel pipe is used for enhancing the strength and rigidity of the joint core area, mass production of the whole joint can be achieved, and the manufacturing cost is low; joint connection operation is simple, construction is convenient, safety and reliability are achieved, the construction progress can be accelerated, and cost is reduced.
本发明公开了一种新型装配式预应力混凝土管桩柱节点及制作方法，包括上部装配式预应力混凝土管桩、下部装配式预应力混凝土管桩、钢筋骨架和芯钢管；钢筋骨架为一个整体，包括上、下部装配式预应力混凝土管桩柱配筋、梁配筋及节点核心区配筋，上、下部装配式预应力混凝土管桩柱配筋包括管桩柱纵筋、管桩柱箍筋；节点核心区配筋包括芯钢管、纵筋及加密箍筋组成的节点环箍，梁配筋包括梁纵筋、梁箍筋。梁纵筋节点核心区的部分经过弯曲处理，能够紧密包裹节点核心区的芯钢管且保持芯钢管不掉落。芯钢管的作用为加强节点核心区强度及刚度，整个节点制作可实现量产化，造价低；节点连接操作简单，施工方便，安全可靠，能够加快施工进度，降低成本。
