Horizontal splicing, pulling and vertical rotating device for single-column inward-inclined steel tower of steel box girder cable-stayed bridge and construction method
The invention relates to a steel box girder cable-stayed bridge single-column inward-inclined steel tower horizontal splicing, pulling and vertical rotating device and a construction method.The steel box girder cable-stayed bridge single-column inward-inclined steel tower horizontal splicing, pulling and vertical rotating device comprises a steel tower, a pressing rod, a traction cable steel strand and a pull rod steel strand, the steel tower comprises an upper steel tower section and a lower steel tower section, the upper steel tower section and the lower steel tower section are connected through a vertical rotating hinge piece, and a first rotating hinge base is arranged at one end of the pressing rod; one end of the pressing rod is hinged to a pressing rod main tower hinged support on the side wall of the lower portion of the upper steel tower section through a first rotating hinged support, the other end of the pressing rod is provided with a second rotating hinged support, the second rotating hinged support is connected with a traction cable anchor beam and a pull rod anchor beam through pin shafts, the traction cable anchor beam is fixedly connected with a traction cable steel strand, and the traction cable steel strand is connected with a traction oil cylinder on a bridge floor. The pull rod anchor beam is fixedly connected with a pull rod steel strand; the pull rod steel strand is hinged with a hinge seat on the side wall of the upper part of the upper steel tower section; the lower steel tower section is inclined and is fixed on the bearing platform; the purposes of ensuring the construction quality, improving the safety coefficient, saving the construction cost and improving the economic benefit can be achieved.
本发明涉及一种钢箱梁斜拉桥独柱内倾钢塔卧拼扳起竖转装置及施工方法，包括钢塔、压杆、牵引索钢绞线和拉杆钢绞线，钢塔包括上钢塔段和下钢塔段，上钢塔段与下钢塔段之间通过竖转铰接件连接，压杆的一端设有第一转铰座，通过第一转铰座与上钢塔段下部侧壁上的压杆主塔铰座铰接，压杆的另一端设有第二转铰座，第二转铰座上通过销轴分别连接有牵引索锚梁和拉杆锚梁，牵引索锚梁与牵引索钢绞线连接固定，牵引索钢绞线与桥面上的牵引油缸相连接，拉杆锚梁与拉杆钢绞线连接固定，拉杆钢绞线与上钢塔段上部侧壁上的铰接座铰接；下钢塔段呈倾斜状并固定在承台上；本发明可以保证施工质量、提高安全系数、节省施工成本、提高经济效益的目的。
