Prefabricated plate beam erecting method

Abstract

The invention discloses a prefabricated plate beam erecting method, and relates to the field of prefabricated plate beam installation construction. The prefabricated plate beam erecting method comprises the steps that S1, two parallel trusses are arranged on two adjacent bridge piers along the direction of a bridge, meanwhile a track used for allowing a beam-shifting trolley to walk is arranged on the top faces of the two trusses, and the beam-shifting trolley is erected on the track; S2, a beam transporting vehicle transports a prefabricated plate beam to a first position, and the prefabricated plate beam is kept to be parallel to the bridge direction; S3, the beam-shifting trolley hoists the prefabricated plate beam to be close to one end of a second position, and meanwhile the prefabricated plate beam and the beam-shifting trolley are driven to move together along the direction of the bridge till the prefabricated plate beam reaches to the second position; S4, the prefabricated plate beam is placed on the second position; and S5, a next prefabricated plate beam is transported by the beam transporting vehicle to the first position, and the step S2, the step S3 and the step S4 are circulated till construction of all prefabricated plate beams of the two adjacent bridge piers is completed. According to the prefabricated plate beam erecting method, construction is convenient, and using of large bridging hoisting equipment in the bridge erecting process is effectively reduced.

Description

technical field [0001] The invention relates to the field of installation and construction of prefabricated slab girders, in particular to a method for erecting prefabricated slab girders. Background technique [0002] With the rapid development of highway and municipal engineering construction in our country, bridges are used more frequently, especially in the process of highway municipal construction, more and more bridges are under construction. [0003] In the process of bridge construction, in order to shorten the construction period of the entire bridge and interfere with the site environment during the bridge construction process, prefabricated slab girder bridges are widely used. For the installation of prefabricated slab girders, special large-scale bridging equipment is required and cranes, and the bridge construction site is often unable to provide enough space for the arrangement of special large-scale bridging equipment and cranes due to site and environmental c...

[0003] In the process of bridge construction, in order to shorten the construction period of the entire bridge and interfere with the site environment during the bridge construction process, prefabricated slab girder bridges are widely used. For the installation of prefabricated slab girders, special large-scale bridging equipment is required and cranes, and the bridge construction site is often unable to provide enough space for the arrangement of special large-scale bridging equipment and cranes due to site and environmental constraints, and the installation and disassembly process of special large-scale bridging equipment is cumbersome, costly to use and rent Higher, affects the erection speed of the entire bridge, and also greatly increases the bridge construction cost
