It connects.
Optionally, the stop collar of the circumferentially arranged oriented surface groove inner bulge in the curved indentations edge.
Optionally, the curved indentations and the curved protrusion are steel component.
The present invention achieves following technical effect compared with the existing technology: the application is rubbed by being arranged at beam-to-column joint
Supporting element can consume energy by opposite swing between beam column, to effectively improve the shock resistance of structure when an earthquake occurs
Energy；Precast beam, prefabricated post and friction support according to the present invention are prefabricated component simultaneously, and scene, which only needs to install connection, is
Can, construction efficiency is high, is very suitable to the anti-seismic structure design of single-storey factory building.
Further, curved indentations and/or curved protrusion surface coat poly- lubricant layer (such as polytetrafluoroethylene ethylene layer), Neng Gouyou
Effect reduces the coefficient of friction between curved protrusion and curved protrusion, while improving the service life of friction pendulum component.
Detailed description of the invention
It in order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below will be to institute in embodiment
Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only some implementations of the invention
Example, for those of ordinary skill in the art, without creative efforts, can also obtain according to these attached drawings
Obtain other attached drawings.
Fig. 1 is the structure chart of friction pendulum anti-seismic structure provided by the invention.
In figure: 1- precast beam；2- prefabricated post；3- friction support；31- curved protrusion；4- curved indentations；5- stop collar.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
It is of the existing technology to solve the problems, such as the object of the present invention is to provide a kind of friction pendulum anti-seismic structure, make to build
While building structure anti-seismic performance improves, construction efficiency is effectively increased.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Such as Fig. 1, friction pendulum anti-seismic structure provided by the invention, including precast beam 1, prefabricated post 2 and friction support 3,
2 top surface of prefabricated post is provided with the curved indentations 4 to lower recess, the fixed company in 3 upper end of friction support and 1 end bottom surface of precast beam
It connecing, 3 lower end of friction support is curved protrusion 31, and the curved protrusion 31 of friction support 3 is embedded into curved indentations 4, and with
Curved indentations 4 slidably contact the surfaces.
In actual production, connector or built-in fitting are set in relevant position when precast beam 1 produces, at the construction field (site) will
Friction support 3 modes such as is bolted or welds with the interconnecting piece of precast beam 1 and is fixedly connected, and curved indentations 4 can be with
Prefabricated post 2 is integrally formed, and the fixed company at the top of modes and prefabricated post 2 such as bowl-type fashioned iron can also be bolted or weld
It connects；Under usual state, the load on precast beam 1 is transferred in precast beam 1 by friction support 3 as force transferring structure, earthquake hair
When raw, friction support 3 can swing consumption energy by opposite in curved indentations 4, to effectively improve the antidetonation of structure
Performance.
Further, curved indentations 4 and 31 surface of curved protrusion are spherical crown.
Further, the ratio range of curved indentations 4 and the radius of spherical crown of curved protrusion 31 is 1/4~1/2, the ratio root
It is determined according to the seismic behavior of different places.
Further, curved indentations 4 and/or 31 surface of curved protrusion are coated with lubricant layer.
