Connecting frame device for displacement for large steel structure bridge and using method thereof

Abstract

The invention discloses a connecting frame device for large steel structure bridge displacement and a using method of the connecting frame device. The connecting frame device comprises a connecting frame body used for being connected with a sea side supporting frame and a land side supporting frame, and a support structure arranged on the connecting frame body. The support structure comprises a plurality of connecting supports which are connected in sequence. A sliding plate beam is arranged at the bottom of each connecting support, and a height adjusting structure is arranged on each sliding plate beam; fixing bases are arranged at the two ends of the bottom of each connecting support, and a fixing plate is arranged between the fixing bases. The connecting frame device further comprises sliding ways laid on the wharf face, and the number of the sliding ways is matched with the number of the connecting supports. And the sliding plate beam moves along the slideways. The problem of insufficient compression stability of the slender rod in the displacement process of a large steel structure bridge is solved.

Description

technical field [0001] The present invention relates to large-scale steel structure bridge displacement technology, more specifically, relates to a kind of connecting frame device and its application method for large-scale steel structure bridge displacement. Background technique [0002] The main span of a large steel structure bridge generally has a self-weight of 10,000 tons. After the main span is manufactured at the wharf of the manufacturing plant, it needs to be transported to the installation site for installation. Since some installation sites do not have large-scale floating cranes of more than 10,000 tons for hoisting, based on Some large steel structure bridges need to be installed at a higher height. In the production plant, they need to be placed on a support frame about 20 meters above the ground for manufacture, and then slide on board together with the support frame as a whole, and transported to the installation site for installation. [0003] Please combin...
