[0002] Steel-concrete composite beam refers to a beam bridge formed by the joint force of steel beam and concrete bridge deck through connectors. The concrete deck is the upper structure of the steel-concrete composite beam and is the load-bearing structure that directly bears the vehicle load. It usually adopts prefabricated assembly construction technology. The installation of prefabricated bridge deck is an important process in the construction of steel-concrete composite beam. Its installation quality directly affects the overall structural safety and service life of the bridge.

[0003] For the installation of conventional steel-concrete composite beam precast bridge decks, a truck crane is generally used to install the precast bridge deck to the designed position. However, the truck crane needs to be moved several times during the installation process, and the construction area occupies a large area, which is not suitable for construction environments with busy traffic and limited underground space. In addition, the installation process of the truck crane is greatly affected by the weather, and the installation accuracy of the bridge deck is difficult to control. Therefore, a construction technology is needed to quickly and accurately install the steel-concrete composite beam precast bridge deck, making the installation more convenient, efficient, and of better quality.

The electric hoist 21 is installed on the sliding mechanism 22, and the sliding mechanism 22 is installed on the main load-bearing beam 10. The sliding mechanism 22 can move laterally along the main load-bearing beam 10. The electric hoist 21 hoists the prefabricated bridge panel 11 through the hook 23, and then drives the electric hoist 21 to move along the main load-bearing beam 10 through the sliding mechanism 22 to move the prefabricated bridge panel 11 to the installation position, thereby realizing the lifting of the prefabricated bridge panel 11. The sliding mechanism 22 belongs to the existing technology, and specifically can adopt a sliding trolley, etc. In this embodiment, the specific structure of the sliding mechanism 22 is not limited, so it is not explained again.

When the prefabricated bridge panels 11 in the same row are installed, it is necessary to move the lifting equipment along the movable rail 41, and lift the movable rail 41 by the reverse chain hoist 53. Then, the reverse transport rod 51 is rotated to transport the movable rail 41 to the moving direction of the lifting equipment, and then the movable pulley 52 moves on the reverse transport rod 51 to move the movable rail 41 to the installation position. Finally, the movable rail 41 is lowered by the reverse chain hoist 53 to limit it, so as to realize the reverse transport of the movable rail 41.
