技术领域technical field
本实用新型涉及公路桥梁工程领域，尤其涉及多方向抗震限位装置及柱墩桥梁抗震结构。The utility model relates to the field of highway bridge engineering, in particular to a multi-directional anti-seismic limiting device and a post-pier bridge anti-seismic structure.
背景技术Background technique
目前，我国绝大部分在役中小型桥梁（尤其是曲线连续箱梁桥）在各种动力作用（如：地震、车船碰撞等）下会发生一定的纵横向位移，另外在一些静力作用（如：伸缩缝卡死、温度作用、静动载的偏心等）下也会产生任意方向的位移，并随时间逐渐累加。这些发生梁体偏位的桥梁已经严重威胁着道路运营的安全，非常有必要对其进行针对性的维修和加固并进行相关设备的研发，从根本上解决问题。At present, most of the small and medium-sized bridges in service in my country (especially the curved continuous box girder bridges) will experience a certain longitudinal and lateral displacement under various dynamic actions (such as earthquakes, vehicle-vessel collision, etc.) Such as: expansion joint stuck, temperature effect, eccentricity of static and dynamic load, etc.) will also produce displacement in any direction, and gradually accumulate over time. These bridges with beam deviations have seriously threatened the safety of road operations. It is very necessary to carry out targeted maintenance and reinforcement and research and development of related equipment to fundamentally solve the problem.
针对桥梁抗震限位的阻尼设备的研究，目前国内常常使用的方法有四种：（1）使用阻尼型支座进行位移约束的方法。这种方法的缺点在于初始阶段约束效果较好，但后续阶段由于支座自身的锈蚀、变形、失效等问题导致约束失效，如不及时更换，可能对桥梁的安全使用造成隐患，而支座的更换施工很麻烦。（2）在梁体两侧设置刚性或半刚性（设置有弹性填塞物）挡板的防偏限位方法。该方法主要是在梁底或盖梁上植筋，通过植筋设置刚性或半刚性挡板，靠挡板的强行阻挡防止梁体发生偏移。上述方法主要存在以下不利因素：其一，限位方式过于强硬，属于强行阻拦式的限位，这不仅可能引起较大的梁体内应力，还可能造成梁体底部、墩顶或盖梁顶的损坏；其二，这种方式限位设备强度较低，一般仅适用于地震动峰值加速度(Ag≤0.15g)地区。（3）在梁体纵向或横向安装带有弹簧的弹性限位设备。这种方法虽改善了强制限位的缺点，具备一定的柔性，但压缩后恢复不了的弹簧会在结构内形成无法释放的内力，这个内力始终是一个安全隐患，威胁着梁体或墩柱的安全，且目前研发的设备只能实现一个方向的限位，无法实现任意方向限位。（4）在梁体某一方向安装定向粘滞阻尼器，该方法虽然在限位后会释放内力，但仍旧只能用于定向限位，不能实现任意方向，一旦出现其他方向或无定向的位移（如扭转位移），设备很容易发生破坏。For the research of damping equipment for bridge seismic limit, there are four methods commonly used in China: (1) The method of using damping bearing for displacement restraint. The disadvantage of this method is that the restraint effect is good in the initial stage, but the restraint fails due to the corrosion, deformation, failure and other problems of the bearing itself in the subsequent stage. If it is not replaced in time, it may cause hidden dangers to the safe use of the bridge. Replacing the construction is troublesome. (2) The anti-bias limit method of setting rigid or semi-rigid (with elastic packing) baffles on both sides of the beam body. The method is mainly to plant reinforcement on the bottom of the beam or the cover beam, set rigid or semi-rigid baffles by planting the reinforcement, and prevent the beam from shifting by the forcible blocking of the baffles. The above methods mainly have the following unfavorable factors: First, the limit method is too strong, which is a forced blocking type limit, which may not only cause a large stress in the beam body, but also cause damage to the bottom of the beam body, the top of the pier or the top of the cover beam. Second, the strength of the limiting device in this way is low, and it is generally only suitable for areas with peak ground acceleration (Ag≤0.15g). (3) Install elastic limit devices with springs in the longitudinal or transverse direction of the beam body. Although this method improves the shortcomings of the forced limit and has a certain flexibility, the spring that cannot be recovered after compression will form an internal force that cannot be released in the structure. This internal force is always a safety hazard, threatening the beam or pier column. It is safe, and the currently developed equipment can only achieve limit in one direction, and cannot achieve limit in any direction. (4) Install a directional viscous damper in a certain direction of the beam body. Although this method will release the internal force after the limit, it can only be used for directional limit, and cannot achieve any direction. Displacement (such as torsional displacement), the equipment is prone to damage.
故如何设计能够更好地实现对桥梁梁体任意方向的约束，且能够释放约束应力，降低安全隐患的多方向抗震限位装置及柱墩桥梁抗震结构，成为有待考虑解决的问题。Therefore, how to design multi-directional seismic limiting devices and column-pier bridge seismic structures that can better constrain the bridge beam in any direction, release the constraint stress, and reduce potential safety hazards has become a problem to be considered and solved.

在本实施例中，安装板为截面呈凹形的安装套10的底板，安装套10与缸体4同轴设置，安装套10开口端缸体4的一端固连设置。In this embodiment, the mounting plate is the bottom plate of the mounting sleeve 10 with a concave cross-section, the mounting sleeve 10 is coaxial with the cylinder 4 , and one end of the cylinder 4 at the open end of the mounting sleeve 10 is fixedly connected.
这样，缸体4和安装套10锻造一体成型，结构强度更好，亦方便起到对其中的传感器起到保护作用。In this way, the cylinder block 4 and the mounting sleeve 10 are integrally formed by forging, so that the structural strength is better, and it is convenient to protect the sensor therein.
