Embodiment 1

[0024] (1) Processing and installation of round steel pipe support: The round steel pipe support is processed by Φ299*10mm round pipe, and the height can be adjusted by itself due to the influence of longitudinal and transverse slopes to ensure that the top surface is level or the slope is not greater than 1%. A 400*400*20mmQ235 steel plate is welded at the upper and lower ends. The support of round steel pipes is manually transported and installed, and its lower end is welded to the overhanging eaves of the steel box girder with a distance of 4.65m. Among them, the round steel pipes can be replaced by materials such as I-beams.

[0025] (2) Processing and installation of longitudinal slideway beams: The longitudinal slideway beams are processed with 45b I-beam, and the length of a single set is 12m. The I-beam is welded with a stiffening plate along the longitudinal interval of 50cm. The stiffening plate is processed by Q235 steel plate with an upper bottom of 410mm, a lower ...

Abstract

The invention discloses an installation device of a prefabricated bridge deck, which belongs to the field of bridge construction. The installation device comprises two longitudinal slide-way beams which are symmetrically and fixedly distributed on a top overhanging eave of a steel box beam in parallel, two transverse bearing beams which stretch across the two longitudinal slide-way beams and symmetrically arranged on the two longitudinal slide-way beams in parallel as well as two parallel symmetric longitudinal bearing beams which stretch across the two transverse bearing beams, wherein each longitudinal slide-way beam is respectively provided with a carrying tank and a limiting distribution device which is used for supporting the transverse bearing beam to slide back and forth along the longitudinal direction, each longitudinal slide-way beam is also provided with a gallows, and the gallows is connected to the limiting distribution device through a traction rope and pulls the carrying tank to slide on the longitudinal slide-way beam. The installation device can solve the problem that the prefabricated bridge deck is subjected to the limitation of the installation terrain and is safe to use, convenient and high-efficient to operate and easy to control.

Description

technical field [0001] The invention belongs to the field of bridge construction, in particular to the field of installation of steel-concrete combined beam prefabricated bridge decks. Background technique [0002] The steel-concrete composite girder prefabricated bridge deck is generally prefabricated near the bridge, and the weight of a single piece is about 30t. After the steel girder is erected, it is installed on the ground near the bridge with a large-tonnage crawler crane or a truck crane. Restricted by the topographical conditions on site, some bridge decks cannot be hoisted and installed with existing technology and equipment. Contents of the invention [0003] The object of the present invention is to propose a prefabricated bridge deck installation device that solves the problem that the installation of the prefabricated bridge deck is restricted by terrain, is safe to use, convenient and efficient to operate, and easy to control. [0004] The object of the inv...
