Embodiment Construction
[0043] Such as 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 bridge deck to be installed 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 ho...

The invention provides a method and device for installing a prefabricated bridge deck between steel-concrete composite girder sections. The track is detachably installed with uphill boots and downhill boots, and the truss car is installed on the short track, and the width between the main trusses of the truss car is adjusted to a suitable distance, and the traction system is used to pass the prefabricated slab through the long track and the short track. The combination moves above the target position, and then the lifting system works to make the truss truck off the ground, and finally the hoisting system drops the prefabricated bridge deck to the target position. The invention is convenient and fast, the truss car can be processed and manufactured by using the existing section steel, the production and installation are simple, the engineering cost is low, the way of adding a short track to the long track can quickly move the track forward, reuse it, the operation is simple, and no lifting is required during construction Equipment, multiple working surfaces operate at the same time, construction conditions are not restricted, safe and efficient.
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...
