Embodiment 1

[0033] Such as Figure 1~2 As shown, a vertical damping support includes an upper seat plate 1 and a lower seat plate 2 . Between the upper seat plate 1 and the lower seat plate 2 are provided a bearing portion 11 capable of reducing vibration and energy consumption, and a damping system 3 for reducing vibration and energy consumption.

[0034] The bearing part 11 includes a raised flange 12 arranged on the lower seat plate 1, a hollow accommodation cavity formed by the flange 12 and the lower seat plate 2, an elastic pad 4 arranged in the accommodation cavity, and an upper seat plate 1 fixedly connected support part 13. The elastic pad 4 is a high damping rubber pad or other elastic body material. The support portion 13 is integrally formed with the upper seat plate 1 .

[0035] The top of the accommodating cavity is open. The supporting part 13 is inserted into the accommodating cavity, and the supporting part 13 is in contact with the top of the elastic pad 4 .

Embodiment 2

[0043] Repeat Example 1, except that, as image 3 As shown, the damping system 3 has different structures. The rubber spring damping system of this embodiment includes a guide rod 8 arranged between the upper seat plate 1 and the lower seat plate 2 , and a hollow high-damping rubber sleeve 14 sleeved on the guide rod 8 .

[0044] An installation groove 15 for installing the spring 7 is spaced apart on the inner wall of the high damping rubber sleeve 14 . A spring 7 is arranged in the mounting groove 15 . The guide rod 8 passes along the central axis of the spring 7 .

[0045] The outer surface of the high damping rubber sleeve 14 is provided with a neoprene protective layer.

Abstract

The invention discloses a vertical vibration reduction support. The vertical vibration reduction support comprises an upper support plate and a lower support plate, and a bearing part capable of achieving vibration attenuation and energy dissipation and a damping system used for vibration attenuation and energy dissipation are arranged between the upper support plate and the lower support plate. The vertical vibration reduction support has the remarkable effect that when elastic deformation occurs, the rubber spring damping system and the elastic pad are used for dissipating energy or reducingvertical vibration of the structure at the same time. Due to the design of the bearing part, the device can bear vertical bearing force, and vertical vibration of the structure can be reduced. The device is simple and reliable in structure, clear in force transmission and stress, low in manufacturing cost and convenient to construct and install.

Description

technical field [0001] The invention belongs to the field of vertical vibration control, and in particular relates to a vertical vibration damping support. Background technique [0002] With the continuous development of urban rail transit and elevated lines, the environmental vibration induced by rail transit and elevated lines is increasingly affecting the work and life of urban residents. Due to the vibration of the train itself, the interaction between the wheel and the rail, and the unevenness of the track, the vibration of the train and the track structure will be caused. These vibrations will propagate outward through the surrounding strata, further inducing secondary vibration and noise pollution of nearby underground structures and adjacent buildings. [0003] Studies have shown that the environmental vibration caused by rail transit and elevated lines is mainly vertical vibration, which has a great impact on the safety of buildings that are in close distance for a ...
