Single-section steel truss girder hoisting balancing device, temporary assembly and construction method
The invention discloses a single-section steel truss girder hoisting balancing device, a temporary assembly and a construction method, and relates to the technical field of bridge construction, the device comprises balancing supporting rod sets with the same number as straight web members, and each balancing supporting rod set corresponds to one straight web member; each balance supporting rod set comprises two balance supporting rods which are used for being symmetrically arranged on the two sides of the corresponding straight web member along the corresponding straight web member, one end of each balance supporting rod is used for being connected with the corresponding upper chord member, the other end of each balance supporting rod is used for being connected with the corresponding lower chord member, and through holes allowing the diagonal web members to penetrate through are formed in the middles of the balance supporting rods. And the conflict between the mounting positions of the diagonal web members and the balance supporting rods is avoided. The lifting points are arranged above the arrangement positions of the balance supporting rods, so that when the single-section steel truss girder is lifted, the single-section steel truss girder can be kept balanced, and the single-section steel truss girder cannot incline due to the gravity center problem. The problems that in the prior art, a mode that multiple sections of trussed beams are hoisted after being assembled needs a larger crane type and cannot be implemented under the condition that the construction environment is limited are solved.
本发明公开了一种单节段钢桁梁吊装平衡装置、临时组件及施工方法，涉及桥梁施工技术领域，该装置包括：与直腹杆数量相同的平衡支撑杆组，每组平衡支撑杆组对应一个直腹杆；每组平衡支撑杆组包括两个平衡支撑杆，两个平衡支撑杆用于沿直腹杆对称设置在直腹杆的两侧，平衡支撑杆一端用于连接上弦杆，另一端用于连接下弦杆，平衡支撑杆的中部设有用于斜腹杆穿过的通孔。避免斜腹杆与平衡支撑杆安装位置的冲突。在平衡支撑杆的设置位置上方设置吊点，在吊装单节段钢桁梁时，单节段钢桁梁可以保持平衡，不会因重心问题发生倾斜。解决了现有技术中将多节段桁梁组装后吊装的方式，存在需要更大的吊机型号，并且在施工环境受限的情况下无法实施的问题。
