Large-span composite string truss support node and manufacturing method thereof
The invention discloses a large-span composite string truss support node and a manufacturing method thereof, and solves the technical problems of large node size and high manufacturing and field welding difficulty in the prior art. The support joint comprises a front sealing plate, a rear sealing plate, an inserting plate, a reinforcing mechanism and a guide pipe. The manufacturing method comprises the following steps of: firstly, prefabricating each part of the support node; welding the lower sealing plate at the bottom of the lower reinforcing mechanism; welding the upper reinforcing mechanism at the upper part of the lower reinforcing mechanism; welding the two guide pipes on the front sealing plate; and the upper sealing plate is welded to the upper reinforcing mechanism and the front side sealing plate, and finally the rear side sealing plate is welded to the upper reinforcing mechanism. The structure is simple, the design is scientific and reasonable, the use is convenient, the truss support, the truss chord member and the prestressed inhaul cable are reasonably and compactly connected and combined into a whole, the node size is small, the manufacturing is convenient, the field welding difficulty is reduced, the back anchor design operation is simple and convenient, and the extension size is small.
本发明公开了一种大跨度复合张弦桁架支座节点及其制作方法，解决现有技术节点尺寸大、制作及现场焊接难度大的技术问题。支座节点包括前部封板、后侧封板、插板、增强机构和导管。制作方法为先预制出支座节点各部件，将下部封板焊接在下部增强机构底部，将上部增强机构焊接在下部增强机构上部，将两根导管焊接在前侧封板上，将前侧封板焊接在下部增强机构和下部增强机构侧面，将上部封板分别与上部增强机构和前侧封板焊接，最后将后侧封板焊接上。本发明结构简单、设计科学合理，使用方便，将桁架支座、桁架弦杆与预应力拉索合理紧凑地连接组合一体，节点尺寸小、制作便利，降低了现场焊接难度，背锚设计操作简便，延伸尺寸小。
