Abstract
The utility model discloses a friction pendulum support with a beam falling preventing structure. The friction pendulum support with the beam falling preventing structure is characterized in that the friction pendulum support comprises an upper pendulum, a dual-curve-surface body and a lower pendulum, an upper baffle ring is additionally arranged on the bottom of the upper pendulum of the support, a lower baffle ring is additionally arranged on the top of the lower pendulum of the support, the upper baffle ring used for preventing a beam of the support from falling and the upper pendulum form a whole, and the lower baffle ring used for preventing the beam of the support from falling and the lower pendulum form a whole. The friction pendulum support is reliable in function, low in cost and easy and convenient to manufacture and process, and is provided with the beam falling preventing structure. When the upper pendulum and the dual-curve-surface body make mutual movements due to external force such as earthquakes, the lower pendulum and the dual-curve-surface body make mutual movements. When the upper pendulum moves to design limitation, the upper baffle ring and the dual-curve-surface body make contact and act, and the mutual movements cannot happen continually; when the lower pendulum moves to design limitation, the lower baffle ring and the dual-curve-surface body make contact and act, the mutual movements cannot happen continually, and the function of preventing the beam from falling is achieved.
Description
Technical field
The utility model relates to a kind of Novel friction pendulum bearing can again the damping while in earthquake with girder falling structure.
Background technology
Anti-seismic technology is an important technology field of the engineering constructions such as bridge, building and water conservancy, by adopting the methods such as damping, shock insulation and adjustment structural dynamic characteristic, the dynamic response of engineering structures under the effect such as seismic forces and wind-force can be controlled timely and effectively, thereby guarantee the safety of structure itself.
In recent years, the bridge take friction pendulum support as representative subtracted, shock isolating pedestal has obtained application significantly, became each Important Project first.
Subtract, shock isolating pedestal can reduce the impact failure of earthquake to bridge construction, is the beam that falls but earthquake also has a kind of larger harm to bridge.Once fall from pier stud at earthquake central sill, the larger destruction such as may cause casualties, therefore earthquake falling-off prevention measures is that bridge design needs the structure of paying attention to more.
Utility model content
The purpose of this utility model is to provide a kind of reliable in function, cost lower, and production and processing is easy and have a friction pendulum support of girder falling structure.
The utility model is achieved in that a kind of friction pendulum support with girder falling structure of structure, it is characterized in that: upper pendulum, hyperboloid, the bottom; Upper pendulum bottom at bearing has increased upper baffle ring, has increased lower baffle ring at the bottom top of bearing; For the upper baffle ring of bearing girder falling with on be put into entirety of shape; For lower baffle ring and an entirety of bottom shaping of bearing girder falling.The utility model support body structure is a normal friction pendulum support, has the repertoire of friction pendulum support; Upper pendulum bottom at bearing has increased upper baffle ring, has increased lower baffle ring at the bottom top of bearing.
The utility model has the advantage of: the utility model provides a kind of reliable in function, cost lower, production and processing is easy and have a friction pendulum support of girder falling structure.When the external force such as earthquake make upper pendulum and hyperboloid, motion mutually occurring, there is motion mutually in the bottom and hyperboloid.In the time that upper pendulum is moved to design limit, upper baffle ring contacts with hyperboloid to have an effect and can not continue to occur mutual motion, in the time that the bottom is moved to design limit, lower baffle ring contacts with hyperboloid to have an effect and can not continue mutual motion occurs, and reaches the function of restrainer.
Accompanying drawing explanation
Fig. 1 is the utility model seat structure schematic diagram
Fig. 2 is girder falling functional schematic
Wherein: 1, upper pendulum, 2, hyperboloid, 3, the bottom, 4, upper baffle ring, 5, lower baffle ring.
The specific embodiment
Below in conjunction with accompanying drawing, 1-2 is elaborated to the utility model, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, the utility model, by common friction pendulum support is improved, provides a kind of Novel friction pendulum bearing with girder falling structure at this; Both retained the power transmission of friction pendulum support and subtract, the various functions such as shock insulation, allow again bearing there is girder falling function.As shown in Figure 1, 2: this support system includes pendulum 1, hyperboloid 2, the bottom 3, upper baffle ring 4, lower baffle ring 5.Upper pendulum 1 bottom at bearing has increased upper baffle ring 4, has increased lower baffle ring 5 at the bottom 3 tops of bearing; For the upper baffle ring 4 of bearing girder falling and upper pendulum 1 entirety that is shaped; For the lower baffle ring 5 of bearing girder falling and the bottom 3 entirety that is shaped.
When the external force such as earthquake make upper pendulum 1 and hyperboloid 2, motion mutually occurring, there is motion mutually with hyperboloid 2 in the bottom 3.In the time that upper pendulum 1 is moved to design limit, upper baffle ring 4 contacts with hyperboloid 2 to have an effect and can not continue to occur mutual motion, in the time that the bottom 3 is moved to design limit, lower baffle ring 5 contacts with hyperboloid 2 to have an effect and can not continue mutual motion occurs, and reaches the function of restrainer.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple modification of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
