High-precision quickly-installation cable bent tower stiff framework and construction method
The invention provides a high-precision quick-installation cable bent tower stiff framework and a construction method, and belongs to the technical field of stiff skeletons and construction methods. The problems that when an existing stiff skeleton unit is installed, the skeleton position deviates due to welding deformation, and the construction efficiency and the overall skeleton stability are affected are solved; when the stiff skeleton is installed, the inclination is measured by using a plumb bob, the accuracy is low, and the environmental influence is large. The high-precision quick-installation cable bent tower stiff framework comprises stiff skeleton units and connecting pieces, and reserved sections of corresponding skeleton stand columns of every two adjacent stiff skeleton units are connected through the corresponding connecting pieces. When the stiff skeleton units are installed, the stiff skeleton units are hoisted through a crane tower, the slope of the stiff skeleton units is adjusted through a slope meter to conduct preliminary positioning, and then splicing is performed. Through connection of the connecting pieces, deformation in the welding process is avoided, the stability and the construction efficiency are improved, the slope instrument is low in influence of environmental factors, the stability and the bearing capacity of the whole cable bent tower are improved, and the construction efficiency and the construction quality are further improved.
本发明提供了一种高精度快速安装的索塔劲性骨架及施工方法，属于劲性骨架及施工方法技术领域。为了解决现有的劲性骨架单元安装时因焊接变形引起骨架位置产生偏差，影响施工效率和整体骨架稳定性；劲性骨架安装时利用线锤测量倾斜度，精确度低，受环境影响大的问题。包括劲性骨架单元和连接件，相邻两个劲性骨架单元相对应的骨架立柱的预留段通过连接件连接。安装劲性骨架单元时利用吊塔将劲性骨架单元起吊，通过斜率仪调整劲性骨架单元的斜率进行初步定位，再进行拼装。通过连接件连接，避免焊接过程中发生变形，提高稳定性和施工效率，利用斜率仪受环境因素影响较低，提高整体索塔的稳定性和承载力，进一步提高施工效率，提高施工质量。
