Suspension device used for reinforcing highway bridge and erection method of suspension device

Abstract

The invention particularly relates to a suspension device used for reinforcing a highway bridge. The device comprises a suspension support assembly and a track mechanism. The suspension support assembly comprises multiple suspenders, a transverse rod fixed below the suspenders and a scaffold arranged on the transverse rod. Load-bearing square timber is arranged above the transverse rod, the scaffold is arranged on the load-bearing square timber and laid along the transverse rod, isosceles inverted-triangular steel pipes are arranged at the top ends of the suspenders, the suspenders and the central axes of the isosceles inverted-triangular steel pipes are overlapped exactly, the top edge of each isosceles inverted-triangular steel pipe is provided with three sliding wheel mechanisms, the two ends of each top edge are provided with two corresponding sliding wheel mechanisms, and the middle portion of each top edge is provided with the remaining sliding wheel mechanism; and the track mechanism is fixed to a flange of an I beam, and the sliding wheel mechanisms are arranged in the track mechanism. The suspension device does not need to be erected and detached multiple times, labor is saved, the project schedule is quickened, and meanwhile consumption caused by multiple times of detachment and installation of erection materials is avoided as well.

Description

Technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a suspension device for strengthening highway bridges and a method for constructing the suspension device. Background technique [0002] With the development of road and bridge construction, the use of road bridges has become more and more widely used. Under long-term load, the bottom of the beam will be deflection, cracks, concrete spalling, steel bar corrosion and other diseases, which require maintenance of the diseased bridge And reinforcement work. Before strengthening the beam bottom, the first thing to do is to set up a temporary construction platform. However, it is very difficult to set up platforms under the bridge for the areas where the city crosses lines, rivers or valleys. [0003] For urban overpasses, the current general approach is to use the under-bridge lanes to erect supports. However, this will occupy the under-bridge lanes for a long time an...

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.
