Prestress reinforcing structure of connecting portion of vertical supporting body and base and construction method of prestress reinforcing structure
The invention discloses a prestress reinforcing structure of a connecting portion of a vertical supporting body and a base and a construction method of the prestress reinforcing structure. The prestress reinforcing structure comprises herringbone prestress ribs evenly arranged at the bottom of the vertical supporting body, each herringbone prestress rib comprises a straight line section and an arcline section, the straight line sections are arranged in the vertical supporting body, and the arc line sections extend out of the two opposite faces of the vertical supporting body and extend to thebase. The parts, exposed out of the space between the vertical supporting body and the base, of the herringbone prestress ribs form chamfered corner concrete structures in a concrete cast-in-place manner. According to the construction method, through reserved channels, it is guaranteed that the herringbone prestress ribs are through, and the corner concrete structures with chamfers are cast in place through formworks. The force transmission manner of the connecting portion of the vertical supporting body and the base can be improved, the load of the connecting portion is effectively dispersed, and stress concentration at the joint is relieved; the tensile strength, the bending strength and the tilting-resisting moment of the vertical supporting body are improved; and meanwhile, the construction difficulty is low, and the construction period is short.
本发明公开了一种竖向支撑体与底座连接部的预应力加固结构及其施工方法。所述预应力加固结构包括均匀布置在竖向支撑体底部的人字形预应力筋，人字形预应力筋包括直线段和弧线段，直线段设置在竖向支撑体内部，弧线段分别由竖向支撑体的两个相对面伸出并延伸至底座；人字形预应力筋露出于竖向支撑体和底座之间的部分现浇混凝土形成倒角式的边角混凝土结构；其施工方法通过预留通道保证人字形预应力筋贯通，以及采用模板现浇具有倒角的边角混凝土结构。本发明可以改善竖向支撑体与底座连接部的传力方式，有效分散连接部荷载，缓解节点处应力集中；增加竖向支撑体的抗拉、抗弯强度和抗倾力矩；同时施工难度较低，施工周期较短。
