Typhoon area through type steel arch bridge steel arch rib lifting method and alignment adjusting device
The invention provides a typhoon area through type steel arch bridge steel arch rib lifting method and an alignment adjusting device. The device comprises an in-situ splicing section steel arch rib, a horizontal splicing lifting section steel arch rib, a splicing support and a plurality of lifting portal frame systems. The assembling bracket and the lifting portal frame system are vertically arranged on the steel main beam; the lifting portal frame system comprises steel pipe stand columns, wind cables, a supporting mechanism and a lifting system arranged on the supporting mechanism, the supporting mechanism comprises a column top longitudinal beam and a supporting cross beam, and the supporting cross beam and the column top longitudinal beam form a #-shaped structure. The lifting system comprises a lifting jack base, a lifting jack, a plurality of transverse position adjusting jacks and a plurality of longitudinal position adjusting jacks. The horizontally-spliced lifting section steel arch rib is provided with a steel arch rib hanging point, and the steel arch rib hanging point comprises a partition plate, a connecting plate and a carrying pole beam. The construction height of the support and the assembled gantry crane is reduced on the whole, potential safety hazards of construction are reduced, and the method has certain popularization significance for the through steel arch bridge in a typhoon area.
本发明提供一种台风区下承式钢拱桥钢拱肋提升方法及对位调节装置，其装置包括原位拼装段钢拱肋、卧拼提升段钢拱肋、拼装支架、多个提升门架系统；所述拼装支架和提升门架系统都竖向设置在钢主梁上；所述提升门架系统包括钢管立柱、风缆绳、支撑机构和设置在支撑机构上的提升系统，所述支撑机构包括柱顶纵梁、支撑横梁，所述支撑横梁和柱顶纵梁组成井字结构，所述提升系统包括提升千斤顶底座、提升千斤顶和多个横向调位千斤顶和纵向调位千斤顶；所述卧拼提升段钢拱肋上设有钢拱肋吊点，所述钢拱肋吊点包括隔板、连接板、扁担梁。本发明整体上降低了支架和拼装龙门吊的施工高度，减少了施工安全隐患，对于台风区的下承式钢拱桥具有一定的推广意义。
