Embodiment
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, the upper steel ring limit base 2 are fixedly mounted in upper structure part 4, the lower steel ring limit
Position seat 3 is fixedly mounted on lower structural features 5, identical and symmetrical above and below point of upper steel ring limit base 2 and the structure of lower steel ring limit base 3
Cloth；The upper steel ring limit base 2 includes pedestal 6, bearing pin 7 with lower steel ring limit base 3 and is oriented to steel wheel 8, and the installation of bearing pin 7 is present
On body 6, it is oriented to steel wheel 8 and is sleeved on bearing pin 7, be oriented to steel wheel 8 has rotational freedom relative to bearing pin 7；The upper steel ring limit
It is connected between the guiding steel wheel 8 and the guiding steel wheel 8 of lower steel ring limit base 3 of position seat 2 by energy-absorbing buffering steel ring 1.It is oriented to steel wheel 8
Energy-absorbing buffering steel ring 1 is also prevented to a certain extent stress concentration phenomenon occurs.
Local strengthening steel plate 9 is provided between the pedestal 6 of steel ring limit base 2 and upper structure part 4 on described, in institute
State and lower local strengthening steel plate 10 is provided between the pedestal 6 of lower steel ring limit base 3 and lower structural features 5, the upper local strengthening
Consolidated between steel plate 9 and upper structure part 4, between lower local strengthening steel plate 10 and lower structural features 5 by strengthening the phase of anchor pole 11
Even.
Between the pedestal 6 and upper local strengthening steel plate 9 of the upper steel ring limit base 2, the pedestal 6 of lower steel ring limit base 3 with
Detachable connection structure is used between lower local strengthening steel plate 10.
Between the pedestal 6 and upper local strengthening steel plate 9 of the upper steel ring limit base 2, the pedestal 6 of lower steel ring limit base 3 with
It is connected by screw bolts between lower local strengthening steel plate 10.
The energy-absorbing buffering steel ring 1 uses waist type structure, and the both ends of energy-absorbing buffering steel ring 1 are semicircular arc, energy-absorbing buffering steel
The middle part of circle 1 is flat segments.
, will particularly between upper structure part 4 and lower structural features 5 under ground seismic wave function exemplified by when earthquake occurs
Bear cross shear, cause occur relatively transverse displacement between upper structure part 4 and lower structural features 5, when lateral displacement compared with
Hour, energy-absorbing buffering steel ring 1 can be realized in the case where not deforming upon and freely stepped down, now the energy-absorbing buffering without more renewing
Steel ring 1.When lateral displacement is larger, i.e., the 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 oriented to steel wheels 8 by upper and lower two and pull deformation, in energy-absorbing buffering
In the deformation process of steel ring 1, will constantly it absorb and earthquake energy, and to the relatively horizontal of upper structure part 4 and lower structural features 5
Enter row buffering and limitation to displacement, reduce the earthquake response of upper and lower part structural member, so as to be served very to upper and lower part structural member
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
It is bad, now the bearing pin 7 on upper and lower two pedestals 6 need to only be pulled down, 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 have also damaged, only need to lay down pedestal with
Bolt between local strengthening steel plate, you can 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, and can replace with brand-new steel ring limit base.Therefore, critical piece of the present invention replacing and installation all very just
Victory, and it is 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 for being oriented to steel wheel 8
According to adaptation manufacture is actually needed, to realize the setting to the energy-absorbing buffering ability of stopping means.During specific setting, it is ensured that energy-absorbing
Steel ring 1 is buffered when largest deformation amount occurs, do not reach capacity lateral displacement yet between upper structure part 4 and lower structural features 5
Amount.
Scheme in embodiment and the scope of patent protection for being not used to the limitation present invention, it is all without departing from carried out by the present invention etc.
Effect implements or change, is both contained in the scope of the claims of this case.
