Assembly type concrete beam-column joint of concrete prefabricated rectangular pipe pile
The invention discloses an assembly type concrete beam-column joint of a concrete prefabricated rectangular pipe pile. The assembly type concrete beam-column joint comprises an upper-layer concrete prefabricated rectangular pipe pile, a lower-layer concrete prefabricated rectangular pipe pile and a structural beam, wherein the beam-column joint area is arranged between the upper-layer concrete prefabricated rectangular pipe pile and the structural beam and between the lower-layer concrete prefabricated rectangular pipe pile and the structural beam, reinforcing steel bars in a pile body of the lower-layer concrete prefabricated rectangular pipe pile extend upwards into the beam-column joint area to be anchored, and a plurality of vertical connecting reinforcing steel bars penetrate through the beam-column joint area and extend into pile cores of the upper-layer concrete prefabricated rectangular pipe pile and the lower-layer concrete prefabricated rectangular pipe pile to be anchored, so that the lower end of the upper-layer concrete prefabricated rectangular pipe pile is in semi-rigid connection or hinged connection with the structural beam, and the upper end of the lower-layer concrete prefabricated rectangular pipe pile is rigidly connected with the structural beam. According to the assembly type concrete beam-column joint, the upper end of the concrete prefabricated rectangular pipe pile is rigidly connected with the beam, rigidity is improved, the lower end is in semi-rigid connection with the beam, and pipe pile bending moment can be conveniently adjusted; and the assembly type concrete beam-column joint can realize mass production and is low in cost, joint connection operation is simple, construction is convenient, safety and reliability are achieved, the construction and installation error-tolerant rate is low, the construction progress is accelerated, and the cost is reduced.
本发明公开了一种混凝土预制矩形管桩的装配式混凝土梁柱节点，包括上层混凝土预制矩形管桩、下层混凝土预制矩形管桩和结构梁，上层、下层混凝土预制矩形管桩和结构梁之间为梁柱节点区，下层混凝土预制矩形管桩桩身中的钢筋向上伸至梁柱节点区中锚固，若干竖向的连接钢筋穿过梁柱节点区并分别伸入上层、下层混凝土预制矩形管桩的桩芯中锚固，使上层混凝土预制矩形管桩下端与结构梁半刚性连接或铰接，下层混凝土预制矩形管桩上端与结构梁刚接。本发明混凝土预制矩形管桩上端与梁刚接，提高刚度，下端与梁半刚接，方便调整管桩弯矩；本发明可实现量产化，造价低；节点连接操作简单，施工方便，安全可靠，施工安装容错率低，加快施工进度，降低成本。
