Novel mutually-embedded swivel hinge based on bridge pier bottom horizontal swivel method
The invention relates to the technical field of bridge construction, in particular to a novel mutually-embedded swivel hinge based on a bridge pier bottom horizontal swivel method, which comprises a swivel hinge upper disc, a swivel hinge lower disc, an upper swivel hinge fixedly connected with the swivel hinge upper disc, and a lower swivel hinge fixedly connected with the swivel hinge lower disc, a rotary positioning pin shaft is mounted between the upper rotary hinge and the lower rotary hinge; a safety leg and a jack counter-force seat are arranged on the rotating hinge lower disc; the lower rotating hinge is a hemisphere with the center protruding, the concave part on the periphery is of a groove-shaped structure with a semi-annular ring face, and the edge is of a table-shaped structure. The upper rotating hinge is a hemisphere with a sunken center, the peripheral protruding part is of a semi-circular ring body structure, and the edge is of a table-shaped structure; the upper rotating hinge and the lower rotating hinge are arranged up and down, and the corresponding surfaces of the upper rotating hinge and the lower rotating hinge are mutually-embedded curved surfaces matched with each other. According to the mutually-embedded curved surface, the area of the contact curved surface is increased, the rotating hinge structure obtains larger bearing capacity and horizontal resistance, and in the bridge rotating process, the overall anti-overturning capacity of the structure is greatly improved.
本发明涉及桥梁施工技术领域，具体为一种基于桥梁墩底水平转体法的新型互嵌式转体铰，包括转铰上盘、转铰下盘，与转铰上盘固结的上转铰、与转铰下盘固结的下转铰；所述上转铰与下转铰之间安装有转动定位销轴；所述转铰下盘上设置有保险腿和千斤顶反力座；所述下转铰为中心凸出的半球体，四周凹陷部分为半环形环面的槽形结构，边缘为台状结构；所述上转铰为中心凹陷的半球体，四周凸出部分为半圆环体结构，边缘为台状结构；所述上转铰与下转铰呈上下设置，其对应的表面为相互配合的互嵌式曲面。本发明提供的互嵌式曲面，增大了接触曲面的面积，让转铰结构获得更大的承载力与水平抗力，在桥梁转体过程中，结构的整体抗倾覆能力大幅提高。
