Bridge rib hoisting and supporting rack integral construction method and device

Abstract

The invention discloses an integration construction method for bridge arch-rib lifting and bracket supporting and a device thereof. The method is that: columns are arranged within the range of arch-rib assembling, and the column is provided with supporting corbels; each section of arch-rib is lifted and arranged on the corbels; lifting beams are positioned on the top part of the columns, and the lifting beam is provided with a longitudinal shift orbit; a crane is positioned on the longitudinal shift orbit, and the crane can move longitudinally on the lifting beam; the crane is also provided with a transversal shift orbit that are provided with a winch which can move transversally; therefore, the winch can move transversely or longitudinally within the arch-rib assembling scope and provide convenience for lifting arch-ribs to each assembling place. By integrating the brackets of lifting with that of supporting, the invention has the advantages of reducing the equipment used for lifting, flexible, simple operation and short operation period; and since floating crane and overhead crane are not used, investment of equipment and capital is shortened; the invention can be used for the arch-rib assembling and various bridge lifting construction fields.

Description

technical field [0001] The invention relates to an integrated construction method and device for bridge arch rib hoisting and supporting supports, and belongs to the technical field of bridge construction. Background technique [0002] For steel arch bridges or bridges with steel-concrete combined structures, the steel components are usually processed in the factory, and then transported to the assembly site for assembly at the construction site. In the prior art, the assembly of arch ribs is to set up support brackets within the installation range, and lift the arch rib rods on the transport barge to the assembly position by floating cranes on the water surface for assembly. Due to the large volume and heavy weight of the arch ribs, there are some disadvantages in the use of floating cranes for lifting. The floating cranes are not flexible enough, the operation is complicated, and the construction time is long. Moreover, if the water level of the arch rib of the arch bridg...

AI Technical Summary

Problems solved by technology

Due to the large volume and heavy weight of the arch rib, there are some disadvantages in the lifting of the floating crane. The floating crane is not flexible enough, the operation is complicated, and the construction time is long.

Moreover, if the water level of the arch rib of the arch bridge is relatively shallow, or part of the position is on land, the lifting capacity of the floating crane is not enough to meet the lifting and assembly requirements of the arch rib, then it is necessary to add lifting equipment on land such as cranes or gantry cranes for lifting. The construction is more complicated, which increases the investment in equipment and prolongs the assembly time
