Abstract
The utility model discloses a cylindrical-face-type friction swing-ball-type support. The cylindrical-face-type friction swing-ball-type support comprises a spherical crown, an upper support plate and a lower support plate. The spherical crown is arranged between the upper support plate and the lower support plate, the upper concave face of the spherical crown and the lower concave face of the upper support plate are matched cylindrical faces, the lower convex face of the spherical crown and the upper concave face of the lower support plate are matched spherical faces, and limit devices for preventing the upper support plate and the lower support plate from swinging relatively are arranged on two sides of the lower support plate. According to the cylindrical-face-type friction swing-ball-type support, when an earthquake happens, the limit devices become ineffective in limiting positions, the upper support plate and the spherical crown can swing relatively and freely, and therefore kinetic energy produced by the earthquake is converted into potential energy. Meanwhile, when the spherical crown swings, frictional resistance can offset part of earthquake energy, therefore an earthquake period is prolonged, and an earthquake reduction effect is achieved; and the potential energy can form recovery force to enable the support to reset. The cylindrical-face-type friction swing-ball-type support is simple in structure, reasonable in design, high in bearing capacity and capable of meeting earthquake proof requirements in bridge engineering.
Description
Technical field
The utility model relates to the bridge pad technical field, refers to it is a kind of cylindrical friction pendulum spherical bearing particularly.
Background technology
In the design of bridge construction, often to consider that earthquake is to the influence of engineering structures.Bearing not only will be given substructure with the Load Transfer on bridge construction top, and absorb rotation, displacement as the important component of bridge construction, also should possess certain function of shock insulation that subtracts.
At present, domestic friction pendulum vibration absorption and isolation support plane of oscillation for bridge engineering is sphere, also can produce vertical lifting displacement and horizontal force when discharging the bridge temperature movement, is unfavorable for the integral bridge structure stress.Therefore, need existing bridge pad is improved.
The utility model content
The purpose of this utility model is exactly the deficiency that will solve the above-mentioned background technology, provides a kind of supporting capacity the high cylindrical friction pendulum spherical bearing that also can satisfy bridge engineering antidetonation demand.
The technical solution of the utility model is: a kind of cylindrical friction pendulum spherical bearing, it comprises spherical crown, upper bracket plate and lower support plate, described spherical crown is arranged between upper bracket plate and the lower support plate, it is characterized in that: the last convex surface of described spherical crown and the concave surface of upper bracket plate are the cylindroid of mutual coupling, the following convex surface of described spherical crown and the upper recess surface of lower support plate are the spherical of mutual coupling, are provided with in the both sides of lower support plate to prevent upper bracket plate, the lower support plate stopping means of swing relatively.
In such scheme:
Be provided with the swing wearing plate between described upper bracket plate and the spherical crown.
Be provided with the rotation wearing plate between described spherical crown and the lower support plate.
One end of described stopping means is stuck in the side of lower support plate, and the other end of stopping means is fixedlyed connected with the upper bracket plate by bolt.
Cylindrical friction pendulum spherical bearing of the present utility model; cooperate with sphere between the lower support plate upper recess surface to satisfy by convex surface under the spherical crown under the normal condition and rotate requirement; and the recessed cylinder of the epirelief cylinder of the spherical crown that matches and upper bracket plate axially is non-spacing direction; it is activity direction; can make between upper bracket plate and the spherical crown and carry out relative horizontal slip; discharging bridge expands with heat and contract with cold displacement and does not produce additional vertical lifting displacement and horizontal force; this can better protect beam body and bridge pier, is convenient to promote the use of.
When earthquake took place, when the horizontal force that earthquake gives lower support plate surpassed set-point, stopping means was cut off, and the spacing constraint of bearing is disengaged, and the cylinder swing friction pair of spherical crown can freely swing, thereby the kinetic energy that earthquake is produced is converted to potential energy.Simultaneously, in the process of spherical crown swing, frictional resistance consumes a part of earthquake energy again.Like this, prolonged earthquake period, reach the effect of damping, and potential energy can form restoring force, bearing is resetted.
