Abstract

The invention relates to a concrete-filled steel tube arch bridge arch rib setting clamp which comprises a construction support system, a jack, arc-shaped steel carrying plates, arch rib fixing steelplates, steel tube arch rib fixing supports, fastening lug plates, an arc-shaped integral type steel channel, opposite-pull adjustable long screws, arch rib opposite-pull temporary connecting plates,a steel tube arch rib joint, a continuous type stress testing meter, steel tube arch ribs, lug plate fastening bolts, adjustable steel plate top plates, adjustable bolt groups, adjustable steel platebases, a hinge shaft and intermediate batten plates. The construction support system is arranged on the lower portion of a concrete-filled steel tube arch bridge. The upper portion of the constructionsupport system is fixed to reinforcing supporting steel plates through reinforcing steel tube containing steel tubes. The corresponding adjustable steel plate top plate and the corresponding adjustable bolt group are arranged on the upper portion of the reinforcing supporting steel plate on one side to adjust the height, and the jack is arranged on the upper portion of the reinforcing supportingsteel plate on the other side. The clamp has the beneficial effects that the steel tube arch rib fixing supports are arranged, the stability in steel tube arch rib installation construction operationis improved, and butt joint accuracy is effectively guaranteed.

Description

technical field [0001] The invention relates to a jig for shaping the arch rib of a steel pipe concrete arch bridge and a construction method, which belongs to the field of civil engineering and is suitable for the construction of a jig for shaping the arch rib of a steel pipe concrete arch bridge. Background technique [0002] In recent years, my country's road and bridge engineering projects have been increasing continuously, and its construction scale has been continuously expanding, thus promoting the development of my country's road and bridge projects. The material used in the construction of concrete-filled steel tube arch bridges is a new type of combined structure, which has good compressive, seismic and impact resistance properties, and the construction technology of steel tube concrete has large span, high strength, good plasticity, fatigue resistance and simple construction. , can reduce the construction cost, shorten the construction period, can play the role of...
