Detailed description of the invention
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figures 1-4, a kind of stopping means with energy-absorbing buffering ability, including energy-absorbing buffering steel ring 1, upper steel ring
Limit base 2 and lower steel ring limit base 3, described upper steel ring limit base 2 is fixedly mounted in upper structure part 4, and described lower steel ring limits
Position seat 3 is fixedly mounted on lower structural features 5, identical and symmetrical above and below with lower steel ring limit base 3 structure point of upper steel ring limit base 2
Cloth；Described upper steel ring limit base 2 and lower steel ring limit base 3 all include pedestal 6, bearing pin 7 and guide steel wheel 8, and bearing pin 7 is installed present
On body 6, guide steel wheel 8 and be sleeved on bearing pin 7, guide steel wheel 8, relative to bearing pin 7, there is rotational freedom；Described upper steel ring limits
Guiding of position seat 2 is connected by energy-absorbing buffering steel ring 1 between steel wheel 8 and the guiding steel wheel 8 of lower steel ring limit base 3.Guide steel wheel 8
It is also prevented from energy-absorbing buffering steel ring 1 to a certain extent and stress concentration phenomenon occurs.
It is provided with local strengthening steel plate 9, in institute between pedestal 6 and the upper structure part 4 of steel ring limit base 2 on described
State and between the pedestal 6 of lower steel ring limit base 3 and lower structural features 5, be provided with lower local strengthening steel plate 10, described upper local strengthening
All by strengthening anchor pole 11 phase admittedly between steel plate 9 with upper structure part 4, between lower local strengthening steel plate 10 and lower structural features 5
Even.
Between pedestal 6 and the upper local strengthening steel plate 9 of described upper steel ring limit base 2, the pedestal of lower steel ring limit base 36 with
Detachable attachment structure is all used between lower local strengthening steel plate 10.
Between pedestal 6 and the upper local strengthening steel plate 9 of described upper steel ring limit base 2, the pedestal of lower steel ring limit base 36 with
Between lower local strengthening steel plate 10 the most with bolts.
Described energy-absorbing buffering steel ring 1 uses waist type structure, energy-absorbing buffering steel ring 1 two ends to be semicircular arc, energy-absorbing buffering steel
It is flat segments in the middle part of circle 1.
As a example by during so that earthquake to occur, under ground seismic wave function, particularly will between upper structure part 4 and lower structural features 5
Bear cross shear, cause occurring between upper structure part 4 and lower structural features 5 relatively transverse displacement, when lateral displacement relatively
Hour, energy-absorbing buffering steel ring 1 can realize freely stepping down, now without the energy-absorbing buffering more renewed in the case of not deforming upon
Steel ring 1.When lateral displacement is bigger, i.e. relatively transverse displacement between upper structure part 4 and lower structural features 5 has exceeded
The remained amount of energy-absorbing buffering steel ring 1, energy-absorbing buffering steel ring 1 will be guided steel wheel 8 tractives by upper and lower two and deform, at energy-absorbing buffering
In steel ring 1 deformation process, will constantly absorb and earthquake energy, and relative with lower structural features 5 horizontal to upper structure part 4
Buffer to displacement and limit, reducing the earthquake response of upper and lower part structural member, thus upper and lower part structural member is served very
Good protection.
After earthquake terminates, upper structure part 4 and lower structural features 5 are saved from damage, but energy-absorbing buffering steel ring 1 is damaged
Bad, now only the bearing pin 7 on upper and lower two pedestals 6 need to be pulled down, just the energy-absorbing buffering steel ring 1 of damage can be pulled down, then change
Upper brand-new energy-absorbing buffering steel ring 1.If upper steel ring limit base 2 and lower steel ring limit base 3 damage the most, only need to lay down pedestal with
Bolt between local strengthening steel plate, can be by upper and lower two pedestals 6 respectively from upper local strengthening steel plate 9 and lower local strengthening steel
Plate 10 is pulled down, the most replaceable brand-new steel ring limit base.Therefore, critical piece of the present invention replacing and install the most just
Victory, and time saving and energy saving.
According to the difference of actual anti-seismic performance, energy-absorbing buffering steel ring 1, pedestal 6, bearing pin 7 and the size of guiding steel wheel 8
According to being actually needed adaptive manufacture, to realize the setting of the energy-absorbing buffering ability to stopping means.When specifically setting, it is ensured that energy-absorbing
When there is largest deformation amount in buffering steel ring 1, do not reach capacity between upper structure part 4 and lower structural features 5 lateral displacement yet
Amount.
Scheme in embodiment is also not used to limit the scope of patent protection of the present invention, all without departing from the present invention do etc.
Effect is implemented or change, is both contained in the scope of the claims of this case.
