Box-type bridge prestressed tendon accurate alignment installation device and installation method thereof
The invention discloses a box-type bridge prestressed tendon accurate alignment installation device and an installation method thereof, and relates to the technical field of bridge construction. The box-type bridge prestressed tendon accurate alignment installation device comprises a door-type frame, an upper end cross beam, a threading device, a wire conduit and a conical wire leading head, and the cross beam and an inclined support beam can improve the strength of the door-type frame; a sling chain lifting point is arranged on one side, close to the portal frame, of the upper end cross beam,so that a lifter is convenient to mount, and the threader is adjusted during threading; flanges are welded to the two ends of the wire conduit, and the threader, the wire conduit and the preformed hole are connected through the flanges to ensure centering of the threader, the wire conduit and the preformed hole; the operation hole and an observation hole are convenient for observing the strand pulling operation process and timely adjusting, so that the strand pulling efficiency is improved; and the device can be repeatedly used for multiple times and can be operated by only 2-3 persons, so that the mounting period is greatly shortened, and the mounting cost is reduced.
本发明公开了一种箱型桥预应力筋精准对位安装装置及其安装方法，涉及桥梁施工技术领域，包括门型架、上端横梁、穿线设备、导线管和锥形引线头，横梁和斜支撑梁能够提升门型架的强度；吊链吊点设置于上端横梁靠近门型架的一侧，便于安装提升器，确保穿线时调整穿线器；导线管两端焊接法兰，借助法兰实现穿线器、导线管和预留孔的连接，确保三者的对中；操作孔和观察孔便于观察穿束作业过程，并适时进行调整，提高穿束效率；且装置可以多次重复使用，只需2‑3人即可操作，大大缩短安装周期、降低安装成本。
