Segment-assembled integrated bridge erecting machine and its construction method

Abstract

The invention discloses a segment-assembled and integrated bridge erecting machine and a construction method thereof, comprising: a main beam cantilevered along the erection direction, a hanging connection mechanism movably arranged on the main beam, and the hanging connection mechanism can be connected with the hanging connection mechanism. Dismantling and connecting the hanging; the hanging includes: a cross beam and a pair of short beams arranged below the cross beam, the short beams are perpendicular to the cross beam and are respectively close to both ends of the cross beam, and the short beams are close to the cross beam The positions of the ends are respectively provided with vertical segment beam suspension points; the lower bottom surface of the transverse beam is provided with pier column suspension points. The invention has universal hanging, which can hoist pier top blocks, segment beams and pier columns, avoid frequent dismantling and replacement of hangings during construction, and improve construction efficiency.

Description

technical field [0001] The invention relates to the technical field of bridge construction equipment. More specifically, the present invention relates to a segment-assembled integrated bridge erecting machine and a construction method thereof. Background technique [0002] Prefabrication of on-site concrete structures in the field of bridge construction has become a trend. At present, crawler cranes are generally used on the construction site of prefabricated bridges to erect prefabricated pier columns, cover beams and other substructures, which occupy a large area, require a lot of manual assistance, low construction efficiency, and cause adverse effects on surrounding traffic and environmental protection. Therefore, there is an urgent need for an integrated bridge erecting machine to simultaneously complete the erection of segmental beams, pier columns and pier top blocks. In addition, it is often necessary to hoist pier top blocks, segmental beams and pier columns durin...

Problems solved by technology

At present, crawler cranes are generally used on the construction site of prefabricated bridges to erect prefabricated pier columns, cover beams and other substructures, which occupy a large area, require a lot of manual assistance, low construction efficiency, and cause adverse effects on surrounding traffic and environmental protection. Therefore, there is an urgent need for an integrated bridge erecting machine to simultaneously complete the erection of segmental beams, pier columns and pier top blocks

In addition, it is often necessary to hoist pier top blocks, segmental beams and pier columns during bridge construction. Since the hoisting points of each target object are different, different hoisting tools need to be used. During the construction process, the hoisting needs to be frequently disassembled and replaced. It affects the construction efficiency and construction quality, so there is an urgent need for a universal hanging
