Annular prestress structure for bridge tower column and construction method
The invention provides an annular prestress structure for a bridge tower column, which comprises a standard tower column, an elastic connecting device, an annular telescopic stress device and a reinforced concrete support frame, and is characterized in that the elastic connecting device is arranged in a steel reinforcement framework of the standard tower column; the two ends of the elastic connecting device are connected with the circumferential telescopic stress devices arranged in the circumferential direction of the steel reinforcement framework correspondingly and are fixed in a pouring mode through the reinforced concrete supporting frame. The invention further provides a construction method for the circumferential prestress structure of the bridge tower column. The elastic connecting device is arranged in the standard tower column, concrete materials can be saved, and the pressure resistance and the shock resistance of the standard tower column are improved. The elastic connecting devices are symmetrically arranged in a staggered mode, and the bearing capacity of the standard tower column is improved. The construction method is easy to implement, through spring design simulation calculation, the feasibility is high, and the manufacturing cost is low.
本发明提供了一种用于桥梁塔柱环向预应力结构，包括标准塔柱、弹性连接装置、环向伸缩应力装置以及钢筋混凝土支撑架，所述标准塔柱的钢筋骨架内安置弹性连接装置，弹性连接装置的两端分别与钢筋骨架周向设置的环向伸缩应力装置进行连接并通过钢筋混凝土支撑架进行浇筑固定。本发明还提供了一种用于桥梁塔柱环向预应力结构的施工方法。本发明的标准塔柱内设置弹性连接装置，能够节省混凝土材料，提高标准塔柱抗压性和抗震性。本发明的弹性连接装置为交错且对称布置，提高标准塔柱的承载力。本发明的施工方法比较容易实现，而且经过弹簧设计模拟计算，可实施性强，造价低廉。
