Hinged column foot inhaul cable joint of large-span cable-stayed structure
The invention relates to a hinged column foot inhaul cable joint of a large-span cable-stayed structure. The hinged column foot inhaul cable joint of the large-span cable-stayed structure comprises a lug plate group fixedly connected with a lower steel column, wherein the lug plate group comprises multiple lug plates arranged in parallel; one end of each lug plate is fixedly connected with the lower steel column; the other end of each lug plate is movably connected with an inhaul cable; the lower steel column is hinged with an upper steel column through a column foot connecting plate; the column base connecting plate is provided with open grooves for the lug plates to penetrate through; a vertical annular plate is arranged outside the lower steel column; the outer surface of the vertical annular plate is connected with steel beams/steel supports; and the lug plates and the steel beams/steel supports do not interfere with each other. Compared with the prior art, according to the hinged column foot inhaul cable joint of the large-span cable-stayed structure provided by the invention, under the condition of complex stress of multi-structural component connection, sufficient bearing capacity can be provided, the joint size can be reduced, the appearance is attractive, and construction installation and follow-up adjustment are facilitated; and aiming at the design of a hinged column foot in the cable-stayed structure, the characteristics of reliability and simplicity in construction can be considered, and the hinged column foot cannot conflict with the inhaul cables.
本发明涉及一种大跨度斜拉结构的铰接柱脚拉索节点，包括与下部钢柱固定连接的耳板组，耳板组包括多个相互平行设置的耳板，耳板的一端与下部钢柱固定连接，耳板的另一端与拉索活动连接，下部钢柱通过柱脚连接板与上部钢柱铰接，柱脚连接板上设有用于穿过耳板的开槽，下部钢柱外设置有竖向环板，竖向环板的外表面与钢梁/钢支撑连接，耳板与钢梁/钢支撑之间不发生干涉。与现有技术相比，本发明在多结构构件连接的复杂受力情况下，既能提供足够承载力，又能减小节点体积、造型美观、便于施工安装与后续调节；并且针对斜拉结构中铰接柱脚的设计，本发明能够兼顾可靠性与施工简单的特点、且不会与拉索发生冲突。
