Bridge tower area cable-free beam section installation structure
The invention relates to a bridge tower area cable-free beam section installation structure. The structure comprises two temporary beam rods which are symmetrically arranged between two middle tower columns of a main tower and located above a lower cross beam, and the temporary beam rods are arc-shaped beams protruding downwards. Inclined supporting rods are used for supporting the temporary beam rods on the middle tower columns, the multiple inclined supporting rods are arranged in an inclined mode, and the upper ends of the inclined supporting rods are evenly fixed to different positions of the temporary beam rods; inclined strut embedded parts are used for being connected with the corresponding inclined supporting rods so that the inclined supporting rods can be fixed relative to the middle tower columns. The number of on-cable cranes is two, and the on-cable cranes are used for transporting the cable-free beam sections of a main beam, are erected on the two temporary beam rods respectively and can move in the length direction of the temporary beam rods; the upper ends of a number of temporary inhaul cables are connected with the two temporary beam rods correspondingly, and the lower ends of the temporary inhaul cables are used for being connected with the cable-free beam sections to be installed. The installation structure has the advantages of simple construction process, flexibility and convenience in construction and capability of synchronously and symmetrically constructing.
本发明涉及桥梁塔区无索梁段安装结构，包括两根对称设在主塔的两根中塔柱之间且位于下横梁的上方的临时梁杆，临时梁杆为下凸的弧形梁；斜撑杆用于将临时梁杆支撑在中塔柱上，斜撑杆有多根且倾斜设置，各根斜撑杆的上端均匀固定在临时梁杆的不同位置；斜撑预埋件用于与对应的斜撑杆连接以将斜撑杆相对于中塔柱固定；缆上吊机有两台，用于调运主梁的无索梁段，分别架设在两根临时梁杆上，缆上吊机可沿临时梁杆的长度方向移动；临时拉索有多根，上端分别连接在两根临时梁杆上，下端用于与待安装的无索梁段连接。具有施工过程简单、施工灵活方便、可同步对称施工的优点。
