Embodiment Construction

[0027] The shock-absorbing and isolating support of the tension-compression anti-fall beam provided by the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, it is a structural schematic diagram of a tension-compression anti-fall beam anti-fall beam anti-vibration support provided by the present invention. The structure constituting the shock-absorbing and isolating support of the tension-compression anti-fall beam includes an upper seat plate 3 provided with a concave ring 15, a bottom plate 11 composed of a concentric concave sphere whose inner and outer walls are concentric circular arcs, and a base plate 11 sandwiched between the two. A sliding part composed of a rotating body 4 and a hyperbolic spherical body 6 . Wherein, the upper part of the rotating body is provided with a convex ring 16 that snaps into the above-mentioned concave ring 15, so that the upper seat plate and the ...

Abstract

The invention belongs to the technical field of bridge supports and discloses a pulling pressing beam-falling-resisting seismic-isolation-and-reduction support. According to the technical scheme, the structure of the support comprises an upper base plate, a bottom plate and a sliding part clamped between the upper base plate and the bottom plate. The bottom plate is composed of a concave ball/a cylindrical surface body. The sliding part is composed of a rotating body and a hyperbolic ball/a cylindrical surface body. A periphery circle concave-convex structure is placed between the upper portion of the rotating body and the upper base plate and forms a sliding anti-pulling structure with a plane sliding pair. The lower portion of the rotating body is of a curve ball/cylindrical surface structure. The hyperbolic ball/the cylindrical surface body is clamped between the rotating body and the bottom plate and forms a corresponding curve surface sliding pair through the rotating body and the bottom plate. An anti-pulling sliding pair mechanism is arranged between the rotating body and the bottom face of the bottom plate. When the support of the structure is under the effect of vertical pulling force, collision of parts of the support is avoided. During an earthquake, a seismic-isolation-and-reduction function is achieved, and a bridge, the support and a pier are kept together all the time.

Description

technical field [0001] The invention belongs to the technical field of bridge supports, and in particular relates to a tension-compression anti-drop beam shock-absorbing and isolation support. Background technique [0002] The support is an important part connecting the bridge and the pier. In addition to bearing the vertical pressure of the bridge, in order to meet the vertical tension demand during the normal operation of the bridge, some supports also need to have a tensile function. In order to meet the requirements of the corner of the support, the tensile support currently used must have a certain gap at the tensile structure. When the support is pulled, the support is prone to the phenomenon that the tensile structure first hits and then is pulled, resulting in the tension of the tensile structure. fragile. [0003] In addition, our country is an earthquake-prone area, and the country has a long history of research on bridge anti-seismic and shock-absorbing systems. ...
