The invention relates to an anti-beam-falling device based on bridge body shock absorption. The device is characterized in that the top end of a supporting column slidably connected in a supporting cover at the top of a base extends to the upper part of the supporting cover and is fixedly provided with a supporting disc, and a mounting rod is rotatably connected in a connecting hole in the supporting disc; the two ends of the mounting rod extend to the two sides of the supporting disc correspondingly and are fixedly provided with the same gear ring, the top of the supporting plate at the bottom of one side of the supporting cover is rotationally connected with a rotating cover, the top end of a sliding connection connecting rod in the rotating cover extends to the position above the rotating cover and is rotationally connected with the supporting disc, and a top end rotating gear of the connecting rod is engaged with the gear ring. The two clamping plates are symmetrically and slidablyconnected into the connecting hole and are in transmission connection with the mounting rod, the top ends of the two clamping plates extend to the upper portion of the supporting disc and are provided with bridge plates in a clamped mode, a top positioning plate of the supporting disc is located between the two bridge plates and is clamped with the two bridge plates, and therefore the two bridgeplates can be quickly mounted and limited; therefore, the problem that the bridge plate deviates can be solved.
Description
technical field [0001] The invention belongs to the technical field of bridges, and relates to an anti-falling beam device based on the shock absorption of bridge girder bodies. Background technique [0002] Aseismic resistance of bridges is a relatively complicated problem. Compared with building structures, due to the structural characteristics of bridges, seismic problems and building structures have their own unique aspects. Expansion joint devices are non-structural components that are designed to accommodate the effects of structural material shrinkage, creep, and external environmental temperature changes. Its non-linear problem is not in the building structure. Its existence makes the bridge structure a discontinuous structural system, which makes the seismic response of the bridge structure quite complex. A large number of bridge earthquake damage experience shows that the relative displacement of excessively large pier (abutment) beam at the expansion joint is on...
