Problems solved by technology

In the design stage, considering the stress conditions of the cable stays, the non-motorized vehicle lanes and sidewalks are generally designed outside the stay cables. Based on this design, some bridge decks are located outside the stay cables and are heavy. The stay cables have been installed, but due to the obstruction of the stay cables, the bridge deck c

Example Embodiment

[0028] Such as figure 1 , figure 2 As shown, the present invention provides a cable-stayed bridge steel beam and bridge deck combined hoisting equipment, including a bridge deck crane for hoisting the steel beam, the bridge deck crane includes two horizontally arranged along the bridge The main girder 1 on the inner side of the stay cable 100 of the bridge, the front and rear ends of the two main girders 1 are respectively connected by a front crossbeam and a rear crossbeam 2. The main girder 1 and the front crossbeam and the rear crossbeam 2 are all truss structures. There are two upper chords and two lower chords; each main girder is provided with rear legs 3 at the bottom rear end. The upper end of the rear legs 3 and the lower chord of the main girder 1 are connected by bolts, and the lower ends of the rear legs are supported along the bridge. On the bridge deck crane slide rail 4 on the top surface of the steel beam 101, and anchored with the lifting lugs on the steel beam...

Abstract

The invention discloses cable-stayed bridge steel girder and bridge deck slab combined hoisting equipment and a hoisting method. Steel girders and hoisting equipment of bridge deck slabs are integrally combined, and the steel girders are hoisted by a bridge deck crane. A common cantilever gantry crane is adopted for the bridge deck crane and installed on the bridge deck crane; an electric hoist can be moved to the cantilever end of the gantry crane to avoid interference of a stay cable, and a bridge deck slab at the outer side of the stay cable is conveniently hoisted. The cable-stayed bridgesteel girder and bridge deck slab combined hoisting equipment and the hoisting method are used for municipal hoisting of cable-stayed bridge steel girders and bridge deck slabs, and have the advantages in the construction process that the installing speed is high, the safety effect is good and construction is convenient; meanwhile, the construction cost is also controlled, particularly, the safetyin construction is improved, the requirement for hoisting large-tonnage bridge deck slabs can be met, and a reference is provided for hoisting construction of the bridge steel girders and bridge deckslabs of the same type.

Description

technical field [0001] The invention relates to the technical field of cable-stayed bridge construction, and relates to a combined hoisting device and hoisting method for hoisting steel girders and bridge decks of municipal cable-stayed bridges. Background technique [0002] Steel-concrete composite girder cable-stayed bridges generally include steel girders that make up the main body of the bridge. Cable-stayed cables are installed on both sides of the steel girders to connect with the bridge towers, and concrete bridge decks are laid on the steel girders. During the construction of the cable-stayed bridge, the steel girder is hoisted in sections by the bridge deck crane, and fixed by the cable after hoisting, and the bridge deck is hoisted on the steel girder section by the bridge deck crane in blocks. In the construction of municipal roads, when encountering the construction of bridges across lakes and rivers, municipal cable-stayed bridges in the form of long-span steel-...
