Embodiment Construction
[0043] like Figure 1~7 As shown, a simple method for installing prefabricated bridge decks between steel-concrete composite girder sections includes hoisting the prefabricated bridge decks to be installed to the pre-storage position, and installing long rails 1 and short rails 2 in the area to be installed. The long rails 1 and the short track 2 are detachably installed with uphill boots 3 and downhill boots 4, the short track 2 is installed with a truss car 5, and the width between the main trusses 6 of the truss car 5 is adjusted to a suitable distance, and the traction system is used to 7. Move the prefabricated slab above the target position through the combination of the long track 1 and the short track 2, and then the lifting system 8 works to make the truss truck 5 off the ground, and finally the hoisting system 9 drops the prefabricated bridge deck to the target position. With this structure, the whole construction process does not require hoisting equipment, multiple...

The invention provides an installation method and device for prefabricated bridge decks between beam sections of a steel-concrete composite beam. The method comprises the following steps: hoisting a to-be-mounted prefabricated bridge deck to a pre-storage position, mounting a long rail and a short rail in a to-be-mounted area, detachably mounting an uphill boot and a downhill boot on the long railand the short rail, mounting a truss vehicle on the short rail, adjusting the width between main trusses of the truss vehicle to a proper distance, moving a prefabricated slab to the position above atarget position through the combination of the long rail and the short rail by means of a traction system, then enabling the lifting system to work to make the truss vehicle separated from the ground, and finally enabling the hoisting system to drop the prefabricated bridge deck slab to the target position. The method and the device are convenient and fast to use, the truss vehicle is capable ofbeing manufactured through existing profile steel, easy to manufacture and install, low in engineering cost, and capable of moving forwards fast in a mode that the long rail and the short rail are combined, and the method and the device have the advantages of being used repeatedly, easy to operate, free of hoisting equipment in the construction process, capable of enabling multiple working faces to work at the same time, free of limitation on construction conditions, safe and efficient, and.
Description
technical field [0001] The invention relates to the field of bridge engineering, in particular to a method for installing a prefabricated bridge deck between steel-concrete composite beam sections. Background technique [0002] Long-span steel-concrete composite girder suspension bridges are more and more widely used. The steel girders of the standard girder sections are generally combined with the prefabricated bridge deck in the factory in advance, and then the cable crane is used to install the whole in place on site, but the installation of the prefabricated bridge deck between the girder sections cannot be realized. . At present, prefabricated bridge decks between girder sections are mostly stored on the beam surface in advance when the standard girder sections are combined in the factory, and are hoisted along with the standard girder sections, and installed after the entire bridge section is in place. There are usually two ways to install the prefabricated bridge dec...
