Problems solved by technology

However, it is precisely because of its light weight that when vehicles vibrate due to factors such as uneven road surfaces or due to factors such as the subway roof or vibration sources such as equipment around the factory, it will affect the safety of people in the building. normal work and life
At present, the main solution is to install shock-isolation bearings at the column feet of the main structure, but this method can only isolate the vertical vibration of the ground caused by equipment operation, train vehicles, etc. The horizontal stiffness and rotational stiffness at the rear column foot of the seismic support are greatly reduced, which in turn reduces the horizontal load capacity of the column foot. When the main structure encounters vibration sources such as earthquakes and causes lateral vibration, the stability of the column foot is poor and prone to collapse

Abstract

The invention relates to a vibration isolation column base joint. The vibration isolation column base joint comprises a column base, a first connecting plate, a vertical vibration isolation pad and abottom plate which are connected in sequence, a plurality of horizontal elastic baffles are symmetrically arranged on the side edge of the vertical vibration isolation pad, each horizontal elastic baffle comprises a second supporting plate and a first vertical plate, the second supporting plates are horizontally arranged, a plurality of vertical second vertical plates are arranged on the second supporting plates to form a filling space, the filling space is filled with second elastic bodies, one ends of the first vertical plates are fixed to the bottom plate, the other ends of the first vertical plates penetrate through the second elastic bodies and are fixed to the second supporting plates, and one second vertical plate is connected with the vertical vibration isolation pad and the firstconnecting plate. Compared with the prior art, the vibration isolation column base joint has the advantages of being high in bending resistance and bearing capacity, good in flexibility and the like.

Description

technical field [0001] The invention relates to the field of building vibration control, in particular to a vibration-isolation column base node. Background technique [0002] The steel structure has the characteristics of light weight, fast construction speed and good seismic performance. However, it is precisely because of its light weight that when vehicles vibrate due to factors such as uneven road surfaces or due to factors such as the subway roof or vibration sources such as equipment around the factory, it will affect the safety of people in the building. Normal work and life. At present, the main solution is to install shock-isolation bearings at the column feet of the main structure, but this method can only isolate the vertical vibration of the ground caused by equipment operation, train vehicles, etc. The horizontal stiffness and rotational stiffness at the rear column foot of the seismic support are greatly reduced, which in turn reduces the horizontal load cap...
