Embodiment 1

[0026] Such as figure 1 , figure 2 and image 3 Shown:

[0027] A multi-stage shock-isolation friction pendulum support with pull-out resistance, comprising an upper sealing plate 1 and a lower sealing plate 2, both of which are reserved with a number of evenly distributed bolt holes 3; the upper sealing plate The bottom of the plate 1 is welded with a middle block 4, and the middle block 4 is partially threaded. The middle block 4 is threaded with a threaded sleeve 25, and the sleeve 5 coaxial with the middle block 4 is fixed on the threaded sleeve 25. The sleeve 5 includes two identical and fixedly connected circular platforms, and the diameter of the circular platform gradually increases from top to bottom; a circular groove is opened on the lower sealing plate 2, and a lower support 6 is fixedly connected to the groove by bolts , the lower support 6 is provided with a partially spherical connection groove 7, the connection groove 7 is offset against the middle block 4;...

Embodiment 2

[0038] Such as figure 2 , image 3 , Figure 4 and Figure 5 Shown:

[0039] On the basis of Embodiment 1, optionally, the inner wall of the annular limit baffle 10 is provided with a number of chutes 14 distributed in a circular array, all of which are facing the middle block 4, and all of which slide in the chutes 14 Connected with a shock absorber column 15, a support rod 16 is arranged between the shock absorber column 15 and the middle block 4, and the two ends of the support rod 16 are respectively connected with the shock absorber column 15 and the middle block 4 through a ball joint 17; A buffer spring 18 is arranged between the shock-absorbing column 15 and the slide groove 14 .

[0040] During the swing process, the middle block 4 pushes the shock absorbing column 15 on one side of the swing direction to slide in the chute 14 through the support rod 16, thereby squeezing the corresponding shock absorbing spring, while the middle block 4 pulls the other side thro...

Abstract

The invention relates to the field of building shock insulation, and particularly discloses a multi-stage shock insulation friction pendulum support with an anti-pulling function. The multi-stage shock insulation friction pendulum support comprises an upper sealing plate and a lower sealing plate, wherein bolt holes are reserved in the upper sealing plate and the lower sealing plate; a middle block body is fixed to the bottom of the upper sealing plate, a coaxial sleeve is connected to the middle block body, the sleeve comprises two same circular truncated cones which are fixedly connected, and the diameters of the circular truncated cones are gradually increased from top to bottom; a circular groove is formed in the lower sealing plate, a lower support is fixedly connected into the groove through bolts, a connecting groove with a partial spherical surface shape is formed in the lower support, and the connecting groove abuts against the middle block body; an upper platform and a lower platform are arranged on the lower support, the diameter of the upper platform is larger than that of the lower platform, the inclination angles of the back faces of the upper platform and the lower platform are equal to the inclination angles of the side walls of the circular truncated cones, and rubber bodies with the same inclination angles are arranged on the upper platform and the lower platform; and an annular limiting baffle arranged on the middle block body in a sleeving mode is fixed to the lower support. The multi-stage shock insulation friction pendulum support aims to solve the problem that an existing rubber support is poor in anti-pulling performance.

Description

technical field [0001] The invention relates to the technical field of building shock isolation, and specifically discloses a multi-stage shock-isolation friction pendulum bearing with the function of pulling out. Background technique [0002] The seismic isolation bearings used in the existing building structures mainly include lead core rubber isolation bearings, high damping rubber isolation bearings and sliding friction isolation bearings, etc. The above bearings have high damping, low stiffness, large Deformation, corrosion resistance and other advantages. The rigidity and damping form of the traditional friction pendulum support are relatively simple. When the building is subjected to a rare earthquake, if the sliding displacement is too large, the isolation support of the building or bridge will slide out or pull out upward, causing the entire structure to fail. Therefore, the application of friction pendulum bearings in structures is greatly limited. [0003] Ordin...
