Definitions
- the new seismic isolation device is based on passive control technology in structural control, and is mainly used in spherical tanks. Combining the use of rolling isolation and rubber pad isolation, a ring beam rolling energy dissipation isolation foundation for supporting spherical tanks is proposed.
- the invention mainly includes an upper rolling steel ring beam groove body, a lower rolling steel ring beam groove body, a steel ball and a rubber bead.
- the lower rolling steel ring beam groove body is placed on the ground, and its cross section is an upward opening groove
- the upper rolling steel ring beam groove body is arranged on it, and its cross section is a downward opening groove
- Eight steel balls are evenly arranged between the body and the groove body of the lower rolling steel ring beam, and a ring of rubber pressure strips is arranged around the steel balls. Weld the steel bracket of the spherical storage tank to the foundation.
- the upper rolling steel ring beam groove body and the lower rolling steel ring beam groove body are arc grooves, and the upper rolling steel ring beam groove body and the lower rolling steel ring beam groove body have the same curvature.
- the diameters of steel balls between the upper rolling steel ring beam groove body and the lower rolling steel ring beam groove body are the same.
- the foundation When the invention is in use, the foundation is constructed under the steel bracket of the spherical storage tank, which can effectively reduce the effect of earthquakes on the spherical storage tank.
- the spherical storage tank ring beam rolling energy dissipation foundation can dissipate seismic energy through the rolling ring beam and the deformation of the rubber bead, and at the same time, the foundation can play the role of limit and reset.
- the present invention has the following advantages:
- Figure 1 is a front elevation view of the present invention.
- Figure 2 is a sectional view of the present invention.
- the upper spherical tank and the steel bracket When the inertial force is generated on the upper part of the spherical tank 1 under the action of the earthquake, the upper spherical tank and the steel bracket will have a tendency of lateral movement and deformation of the steel frame, and the inertial force will be downward. It is transmitted to the ring beam foundation. Since the foundation is broken by the rolling layer, lateral displacement will occur, which will cause the overall translation of the upper structure, thereby reducing the internal deformation of the steel frame and the tank under the inertia effect, and reducing the seismic action.
- the surrounding rubber strips have a certain sealing effect. The rubber has large deformation characteristics and can provide a certain damping effect. The combination of the two forms the basis for rolling energy dissipation and vibration isolation supporting the spherical tank.
Abstract
一种支撑球罐的环梁滚动耗能隔震基础，包括上滚动钢环梁槽体(5)、下滚动钢环梁槽体(6)、钢球(7)和橡胶压条(8)，其中，下滚动钢环梁槽体(6)置于地面，其截面为向上开口凹槽，并在其上布置上滚动钢环梁槽体(5)，其截面为向下开口凹槽，上滚动钢环梁槽体(5)和下滚动钢环梁槽体(6)中间均匀布置八个钢球(7)，同时在钢球(7)的周围设置一圈橡胶压条(8)。
Description
本新型隔震装置是基于结构控制中的被动控制技术，主要应用于球罐，结合使用滚动隔震和橡胶垫隔震，提出一种支撑球罐的环梁滚动耗能隔震基础。
目前国内外对于应用于球罐的基础隔震装置的研究主要集中在橡胶垫隔震装置，用它来降低基底剪力和倾覆力矩，减少动液压力，然而对于其它隔震装置如滚动隔震、复合隔震等更是鲜有报道。
发明内容
本发明主要包括上滚动钢环梁槽体、下滚动钢环梁槽体、钢球、橡胶压条。其中，下滚动钢环梁槽体置于地面，其截面为向上开口凹槽，并在其上布置上滚动钢环梁槽体，其截面为向下开口凹槽，而后上滚动钢环梁槽体和下滚动钢环梁槽体中间均匀布置八个钢球，同时在钢球的周围设置一圈橡胶压条。将球形储罐钢支架焊接到该基础上，当地震作用下，球罐上部产生惯性力时，上部球罐和钢支架会产生侧向运动趋势及钢架变形趋势，其惯性力向下传递到环梁基础上，由于基础为滚动层断开，会产生侧向位移，使得上部结构发生整体平动，从而减少钢架和罐体在惯性效应下的内部变形，减少地震作用，环梁周围的橡胶压条在具有一定密封作用，而且橡胶具有大变形特性，可提供一定的阻尼作用，二者联合构成了支撑球罐的滚动耗能隔 震基础。
进一步地，上滚动钢环梁槽体和下滚动钢环梁槽体为弧形凹槽，且上滚动钢环梁槽体和下滚动钢环梁槽体的曲率相同。
进一步地，上滚动钢环梁槽体和下滚动钢环梁槽体之间的钢球直径相同。
本发明在使用时，在球型储罐的钢支架下建造该基础，可以有效的降低地震对球型储罐的作用。当地震发生时该球型储罐环梁滚动耗能基础可以通过滚动环梁，以及橡胶压条的变形来耗散地震能量，同时该基础可以起到限位和复位的作用。
本发明与现有技术相比具有如下优点：
(1)提高装置的稳定性，增加装置的减震耗能能力，降低隔震
装置的造价；
(2)结构简单，便于取材，安装施工简单，造价低廉；
(3)其竖向承压能力强，隔震效果好，具有瞬时复位功能，既能起到支撑上部结构的目的，又能起到隔离地震向上部结构输入的目的，降低破坏性地震对球罐的损坏。
图1为本发明使用正立面图。
图2为本发明剖面图。
附图标记说明：1-球罐；2-支撑架；3-环梁滚动耗能基础层；4-焊接点；5-上滚动钢环梁槽体；6-下滚动钢环梁槽体；7-钢球；8-橡 胶压条。
具体实施方式 如图1和图2所示的支撑球罐的环梁滚动耗能隔震基础的示意简图中，下滚动钢环梁槽体6置于地面，其截面为向上开口凹槽，并在其上布置上滚动钢环梁槽体5，其截面为向下开口凹槽，而后上滚动钢环梁槽体和下滚动钢环梁槽体中间均匀布置八个钢球7，同时在钢球的周围设置一圈橡胶压条8。将球形储罐钢支架2焊接到该基础上，当地震作用下，球罐1上部产生惯性力时，上部球罐和钢支架会产生侧向运动趋势及钢架变形趋势，其惯性力向下传递到环梁基础上，由于基础为滚动层断开，会产生侧向位移，使得上部结构发生整体平动，从而减少钢架和罐体在惯性效应下的内部变形，减少地震作用，环梁周围的橡胶压条在具有一定密封作用的同事，橡胶具有大变形特性，可提供一定的阻尼作用，二者联合构成了支撑球罐的滚动耗能隔震基础。
