Problems solved by technology

like Figure 22 The conventional floor support shown generally has a length of 40-50m and a height of 45-50m. The investment in support materials and labor for such a support is relatively large, and the economy is poor.
, and the construction period is long, which consumes a lot of time for erection and disassembly, which affects the overall work efficiency

Embodiment Construction

[0063] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0064] The telescopic bracket 1 of this technical solution is installed on the top of the transition pier 7 of the suspension bridge, and two are symmetrically installed and arranged according to the central axis of the bridge. After the telescopic bracket 1 is installed, it is divided into two states, namely the extended state and the retracted state. The structure of a single telescopic bracket 1 consists of a main beam 101, a vertical brace 102 for vertically supporting the main beam 101, a horizontal brace 103 for horizontally supporting the main beam 101, including an anchoring corbel 104 and a reverse pull corbel. 105 anchoring mechanism, anchori...

Abstract

The invention discloses a telescopic bracket, including a girder, a vertical diagonal brace and an anchoring mechanism, wherein the anchoring mechanism is used for mounting on the top of the transition pier of the suspension bridge; the first end of the girder is articulated with the anchoring mechanism; the girder may be in a retracted state perpendicular to the anchoring mechanism and adjacent to the side wall of the transition pier of the suspension bridge, when the top surface of the girder is flush with the top surface of the anchoring mechanism, and the second end of the girder is hingedwith the first end of the vertical diagonal brace; the second end of the vertical diagonal brace is used for detachably connecting the side wall of the transition pier of the suspension bridge, and the vertical diagonal brace can be switched between a retracted state which is detached from the side wall of the transition pier of the suspension bridge and parallel to the girder, and a protruding state which is connected with the side wall of the transition pier of the suspension bridge and inclined with the main beam. Through the telescopic bracket, the steel box girder can be temporarily supported, and the construction period of erection and demolition is short, and the use is more flexible and convenient. The invention also discloses a steel box girder hoisting device and hoisting method.

Description

technical field [0001] The invention relates to the hoisting construction of a steel box girder of a suspension bridge, in particular to a telescopic bracket, a steel box girder hoisting device and a hoisting method. Background technique [0002] Steel box girder suspension bridges are mainly composed of cable towers, anchorages, main cables, cable clamps, slings and steel box girders, and multi-span suspension bridges also include transition piers. Among them, the steel box girder is prefabricated in sections, and the prefabricated steel box girder sections are transported to the construction site by transportation equipment for hoisting, and connected with the corresponding slings, and the slings hang the steel box girder on the main cable through cable clamps After all the steel box girders of the whole bridge are hoisted, ring welding is performed between the steel box girder segments, so as to realize the formation of the steel box girder main girder of the suspension b...
