Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 As shown, the anti-swaying telescopic device of the suspension bridge in this embodiment includes a first beam end 1, a second beam end 2, a first comb plate 3 and a second comb plate 4, the first beam end 1 and the second Expansion joints 5 are formed between the ends 2 of the two beams, the head of the first comb plate 3 and the head of the second comb plate 4 are mated with each other, and the gap between the first comb plate 3 and the second comb plate 4 There is a gap for lateral movement. In this embodiment, the first comb plate 3 is a movable comb plate straddling the expansion joint 5 , and the second comb plate 4 is a fixed comb plate.

[0025] Such as Figure 2 to Figure 7 As shown, a first support member 6 is installed on the first beam end 1 , and the root of the first comb plate 3 is rotatably connected ...

Abstract

The invention discloses a telescopic device for preventing suspension bridge from shaking. The device comprises a first beam end part, a second beam end part, a first comb plate and a second comb plate, wherein an expansion joint is formed between the end part of the first beam and the end part of the second beam, and is characterized in that a first support component is arranged at the end part of the first beam, the root part of the first comb plate is rotatably connected to the first support component, a second support component is arranged at the end part of the second beam, and the root part of the second comb plate is rotatably connected to the second support component. Compared with the prior art, a first comb plate of the telescopic device for resisting shaking of the suspension bridge is rotationally connected to a first supporting component located at the end of a first beam, and the second comb plate is rotationally connected to the second supporting component located at theend of the second beam, so that multidirectional displacement of the telescopic device can be achieved, the telescopic device can adapt to shaking of the suspension bridge, and damage to the telescopic device due to shaking of the suspension bridge is avoided.

Description

technical field [0001] The invention relates to the field of expansion joints, in particular to an expansion device capable of resisting shaking of a suspension bridge. Background technique [0002] The suspension bridge is a flexible cable suspension bridge structure whose main load-bearing component is tensioned by the main cable. The self-weight of the main girder, the dead load of the second phase, the live load of the vehicle, the temperature effect, the strong wind, the earthquake and other loads are all transmitted to the main cable through the sling, and finally the main cable transmits all the loads from the main tower or anchorage to the foundation. Expansion joints are structural joints set up to prevent structural cracks or damage to building components due to climate temperature changes (thermal expansion, cold contraction). In order to ensure the safety of personnel and driving, a comb-tooth plate expansion device must be installed at the structural joints. In...
