Description
Technical field
The present invention relates to bridge strengthening engineering device technique fields, refer in particular to a kind of bridge strengthening device.
Background technique
With the development of China's municipal administration, transportation industry, Bridges in Our Country owning amount is up to more than 600,000 seats, however, from me
From the point of view of the disconnected beam accident that state has occurred, it is concentrated mainly on the plate girder bridge or T-type beam bridge of the Mid and minor spans of 80~nineties of last century,
The slow lane more in heavy-duty freight car often occurs for accident, shows as single-beam stress, beam slab cracking, the damage of hinge seam, wet gaping of joints
Etc. features, the use for a long time of present bridge be easy to appear crack conditions.
A kind of bridge strengthening device with shock insulation function disclosed in Chinese patent CN206438424U is equipped with shock insulation and fills
It sets, and earthquake isolating equipment is made of the fixing seat and damping block of its upper and lower ends, although enhancing the stability of bridge, still
It can have the disadvantage in that
1, it is given and is buffered by damping or other modes in the prior art, but in the case where encountering wind-force effect, only to resistance
The effect of gear not can be carried out the effect of water conservancy diversion, so that the pressure of bridge pier is big, and under long-time service condition, it may appear that disconnected
The case where splitting.
2, in the prior art, bridge and bridge pier are set as conventional design, and be easy to causeing can during vehicle driving
So that bridge pressure is excessive, the case where being easy to appear fracture, it is not easy to repair.
Therefore, it is badly in need of researching and developing a kind of bridge strengthening device that can be carried out guide functions and increase bridge endurance.
