Abstract

The invention discloses a bridge telescopic beam structure. The top portion of each of the two end surfaces is provided with a rubber layer, and the bottom portion of each end surface is provided with a steel plate layer. A buffer device is arranged between the two end surfaces. The buffer device comprises two buffer rods which are hinged to each other. Each buffer rod comprises a first linear portion at the middle part and second linear portions at the two ends; the first liner portion is connected to the second linear portions through bent portions; the hinging position is located on the first linear portion of the buffer rod; a flexible housing is arranged on the outer side of the hinging position of the buffer rod; and the space between the buffer rod and the corresponding end surface is filled with a buffer layer. A connecting layer is arranged between the rubber layers on the two end surfaces. The invention also provides an installation method for the bridge telescopic beam structure. According to the invention, shortcomings in the prior art can be overcome, the maintenance operation of the telescopic beam is simplified, and the driving stationarity of a vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a bridge telescopic beam structure and an installation method thereof. Background technique [0002] The telescopic beam of the bridge is one of the places where the whole bridge bears the largest load, which ensures that the bridge does not undergo rigid deformation when it receives external forces or changes in the environment. Due to the particularity of the telescopic beam, its service life is relatively short among the entire bridge components. Chinese invention patent CN102102340B discloses a bridge expansion device and its installation method. Compared with the traditional moller seam technology, the later service life and maintenance cost have been significantly improved. However, the telescopic device of this structure does not change the basic design principle of the traditional telescopic device, and only improves the use and structure of some parts, which...
