Steel reinforcement cage for prestressed concrete pipe pile
The invention provides a steel reinforcement cage for a prestressed concrete pipe pile, and belongs to the technical field of pipe piles. The steel reinforcement cage comprises column steel bars, a steel wire mesh and binding steel wires, and further comprises four-corner hoop columns; each four-corner hoop column is composed of two right-round hoops of the same specification and two oval hoops of the same specification, wherein the length of the short axis of each oval hoop is equal to the diameter length of the corresponding right-round hoop; every two oval hoops penetrate through each other and then form a cross shape with the short axis as the center axis, hoop strips at the cross positions are bound through the binding steel wires, then every two right-round hoops abut against the hoop strips at the lower end and the upper end of the corresponding crossed oval hoop respectively, the abutting positions are bound through the binding steel wires, and the four-corner hoop columns are formed; and the multiple four-corner hoop columns are stacked layer by layer, then the column steel bars are bound around the four-corner hoop columns, then the steel wire mesh is bound, and the steel reinforcement cage is obtained. The steel reinforcement cage adopting the four-corner hoop columns is compact in structure, the phenomena of stretching, contracting, inclined stacking and sliding cannot happen, and extremely high stability is achieved.
一种预应力混凝土管桩用钢筋笼，属于管桩技术领域，包括柱钢筋、钢丝网和绑扎钢丝，还包括四角箍圈柱；所述四角箍圈柱由两只相同规格的正圆形箍圈、两只相同规格的椭圆形箍圈构成，其中椭圆形箍圈的短轴长度等于正圆形箍圈的直径长度；两只椭圆形箍圈互相穿过然后以短轴为中心轴构成交叉状，并将交叉处的箍条用绑扎钢丝进行绑扎，再将两只正圆形箍圈分别抵接在交叉的椭圆形箍圈下端和上端的箍条上并将抵接处用绑扎钢丝进行绑扎，构成四角箍圈柱；将若干个四角箍圈柱层层叠放，然后在四周绑扎柱钢筋，再绑扎钢丝网，得到钢筋笼；这种采用四角箍圈柱的钢筋笼结构紧致，不会出现伸缩、斜叠和滑动现象，具有极强的稳定性。
