Description

TECHNICAL FIELD

[0001] The utility model relates to resonance block technical field, concretely relates to bridge resonance block. BACKGROUND

[0002] Resonance block is used to describe the vibration of an object in a stable frequency range. In a resonance block system, the object is placed on a support structure and connected to the structure through an elastic element. When the system is in a free state, the object will continuously vibrate at its natural frequency, and the frequency of this vibration depends on the mass of the resonance block, the stiffness of the elastic element, and the characteristics of the support structure. At the same time, the resonance block can resonate with external vibrations, thereby eliminating the influence of external vibrations on the connected objects.

[0003] Currently, in the construction process of bridges in earthquake-prone areas, resonance blocks are not installed on the bridges, which leads to the influence of resonance on the bridges during an earthquake, resulting in the rupture of the bridges due to resonance. Therefore, a resonance block for bridges is designed to reduce the risk of bridge rupture caused by resonance. SUMMARY

[0004] The utility model discloses a bridge resonance block to solve the shortcomings in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0010] An internally threaded bushing is fixedly connected to the inner wall of the rubber sleeve, and the side wall of the internally threaded bushing is fixedly connected with a connecting ring, and the upper surface of the connecting ring is fixedly connected to the lower surface of the rubber sleeve.

[0011] Preferably, it further comprises a fixed inner sleeve, the outer side wall of the fixed inner sleeve is fixedly connected to the inner wall of the circular groove, and the inner side wall of the fixed inner sleeve is fixedly connected to the side wall of the guide sleeve, the side wall of the rubber sleeve, and the side wall of the connecting ring.

[0012] The utility model has the following advantages:

[0013] When the bridge is subjected to vibration, the bridge can resonate with the vibration under the action of the rubber sleeve, thereby eliminating the vibration of the bridge, avoiding the influence of resonance on the bridge in the earthquake-prone area, and reducing the risk of bridge fracture caused by resonance.
