Embodiment Construction

[0026] The present invention will be clearly and completely described below in conjunction with the accompanying drawings, so that those skilled in the art can fully implement the present invention without creative work.

[0027] The specific embodiment of the present invention is: as Figure 1-3 As shown, a steel arch rib lifting alignment adjustment device for a down-loaded steel arch bridge in a typhoon area includes a steel arch rib 6 for the in-situ assembly section, a steel arch rib 2 for the horizontal assembly lifting section, and a steel arch rib 6 for the in-situ assembly section. And the assembled support at the bottom of the steel arch rib 2 in the horizontal lifting section 1, a plurality of lifting gantry systems symmetrically arranged relative to the center plane of the steel arch rib;

[0028] Both the assembled bracket 1 and the lifting mast system are vertically arranged on the steel girder 7;

[0029] The lifting mast system 3 includes a steel pipe column 5...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of lifting and installation of steel arch ribs, and in particular relates to a method for lifting steel arch ribs of an under-supported steel arch bridge in a typhoon area and an alignment adjustment device. Background technique [0002] At present, the construction technology of steel arch bridges is relatively mature. There are many construction methods for the steel-concrete composite girder arch bridge with basket basket. Arch behind the beam. The above two schemes have greater safety risks in typhoon areas. Contents of the invention [0003] The invention provides a steel arch rib lifting method and an alignment adjustment device of an under-supported steel arch bridge in a typhoon area, which reduces the construction height of the bracket and the assembled gantry crane, reduces construction safety hazards, and has certain advantages for the under-supported steel arch bridge in the typhoon area. pro...
