Suspension device for strengthening highway bridge and construction method of the suspension device

Abstract

The present invention specifically relates to a suspension device for reinforcing highway bridges, the device includes a suspension bracket assembly and a track mechanism, the suspension bracket assembly includes several suspension rods, a cross bar fixed below the suspension rod and a The scaffolding on the cross bar is provided with a load-bearing square log, and the scaffold is placed on the load-bearing square log and laid along the cross bar. The top of the suspender is provided with an isosceles inverted triangle steel pipe. The suspender just overlaps the central axis of the isosceles inverted triangular steel pipe, and the top edge of the isosceles inverted triangular steel pipe is provided with three sets of pulley mechanisms, wherein two sets of pulley mechanisms are respectively arranged at the two ends of the top edge, and the other set of pulleys The mechanism is arranged in the middle of the top edge; the track mechanism is fixed under the wing plate of the I-beam, and the pulley mechanism is placed in the track mechanism. The device does not need to be built and disassembled many times, which saves labor, speeds up the progress of the project, and also avoids the loss caused by multiple disassembly and assembly of building materials.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a suspension device for reinforcing highway bridges and a construction method of the suspension device. Background technique [0002] With the development of road and bridge construction, road bridges are used more and more widely. Under the long-term load of bridges, the beam bottom will suffer from deflection, cracks, concrete spalling, steel bar corrosion and other diseases, so it is necessary to maintain the bridges with diseases and reinforcement work. Before reinforcing the bottom of the beam, the first thing to do is to set up a temporary construction platform. However, it is very difficult to build platforms under bridges for areas where the city crosses a line, crosses a river, or crosses a valley. [0003] For urban flyovers, the current general practice is to set up supports with the help of the under-bridge lanes. However, this will occupy the ...

Problems solved by technology

However, this will occupy the lane under the bridge for a long time and interfere with the road traffic under the bridge. The existing related technology of building a construction platform from the bridge face downwards by suspension means that the construction platform is suspended under the bridge. , it will not affect the bridge deck and the traffic under the bridge; however, in the implementation process of the prior art, it is necessary to build and dismantle the construction platform on the bridge deck in turn, resulting in cumbersome overall construction procedures, heavy workload, and slow project progress.
