Description
Technical field
The utility model is related to bridge earthquake resistance technical field, and in particular to a kind of friction energy-dissipating slide type Antivibration block dress
Put.
Background technology
A large amount of bridge earthquake disasters, particularly 5.12 Wenchuan earthquakes teach that on the lesson of bridge earthquake, fall beam,
Collision, support damage between Liang Yuliang or Liang Yutai are that extremely frequently earthquake destruction occurs among earthquake；In earthquake-stricken area,
The Antivibration block that most of bridge direction across bridge is set occurs in that different degrees of infringement；Traditional Antivibration block is by increasing
The size and number of steel bars of Antivibration block resists geological process；It has been recognized that the higher the better for block intensity, but on ground
Under shake effect, huge earthquake shock power can be passed to substructure and basis by the excessive rigidity of stop block body on the contrary, be caused
It is difficult to the damage and destruction repaired.
Utility model content
The utility model provides a kind of effectively consumption seismic force, the less friction energy-dissipating slide type antidetonation of bridge failure degree
Stop assembly.
The technical solution adopted in the utility model is：A kind of friction energy-dissipating slide type Antivibration block device, including be arranged on
The Antivibration block at bent cap upper surface two ends and the bearing being arranged between bent cap and beam body；Antivibration block is cube structure, is leaned on
Nearly beam body side is caved inward to form arc surface, and bed course is provided with arc surface.
Further, it is provided with cushion on Antivibration block side and web in the beam body.
Further, the bearing is laminated rubber bearing, and bearing is arranged with bearing cushion block.
Further, the cushion thickness is 30mm, is polytetrafluoroethylene floor.
Further, the cushion is the thick rubber layers of 20-30mm.
Further, the Antivibration block is equal to bearing and bearing cushion block height sum close to beam body side vertical height.
The beneficial effects of the utility model are：
（1）The utility model can give full play to the effect of shock insulation material friction sliding power consumption, while after Antivibration block destruction
Also allow for later period maintenance and replacing；
（2）The utility model can by changing gap between block and beam body, circular arc radius surface, in block vertical height and
End face length is adjusted, and can meet the antidetonation demand of different bridge structures；
（3）The utility model construction is simple, cost is low, with preferable engineering application value, can be widely applied to antidetonation
The higher bridge block of performance requirement.
Brief description of the drawings

Fig. 3 is enlarged diagram at A in Fig. 1.
In figure：1- bent caps, 2- bearing cushion blocks, 3- bearings, 4- Antivibration blocks, 5- beam bodies, 6- cushions, 7- bed courses.
Embodiment
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of friction energy-dissipating slide type Antivibration block device, including it is arranged on the upper surface two ends of bent cap 1
Antivibration block 4 and the bearing 3 that is arranged between bent cap 1 and beam body 5；Antivibration block 4 is cube structure, close to beam body 5 one
Bed course 7 is provided with lateral sunken inside formation arc surface, arc surface.
Further, it is provided with cushion 6 on the side of Antivibration block 4 and web in the beam body 5.
Further, the bearing 3 is laminated rubber bearing, and bearing 3 is arranged with bearing cushion block 2.
Further, the thickness of bed course 7 is 30mm, is polytetrafluoroethylene floor.
Further, the cushion 6 is the thick rubber layers of 20-30mm.
Further, the Antivibration block 4 is equal to bearing 3 and the height of bearing cushion block 2 close to beam body side vertical height
With.
In use, according to the actual antidetonation needs of bridge, before top beam body 5 sets up and installed, being set inside Antivibration block 4
Put some rows and go deep into the reinforcing bar and bent cap 1 of bent cap 1 cast-in-site together, the inner side cambered surface of Antivibration block 4 then is carried out into surface repaiies
Light processing, and coat polytetrafluoroethylene (PTFE) and do bed course 7；In beam body 5 near Antivibration block 4 web and the beam bottom gluing knot of engineering
Cushion rubber layer 6, completes top beam body 5 and sets up installation；Under the geological process of low middling, due to Antivibration block 4 and girder
Between leave certain gap, whole system is in a safe condition；Under severe earthquake action, the displacement of girder exceedes beam body 5 with resisting
When shaking 4 gap of block, beam body 5 can in the inner side arc Seismic Isolation of Isolation Layer of Antivibration block 4 sliding friction energy dissipating, and cambered surface can be utilized
Lifting effect produces weakening effect to transverse component, the energy for being transferred to substructure is reached minimum, it is to avoid body junction is constructed
Into direct damage, and impaired serious Antivibration block 4 is easier quick reparation after shake；The utility model is simple in construction,
Clearly, convenient and quick construction can reach effective restraining ability by reasonably calculating analysis and slides dissipation earthquake Path of Force Transfer
Impact；Scattered and mitigation superstructure seismic (seismal is to abutment and the active force of pile foundation, by the control of bridge impaction lesion one
Determine in scope, bridge is repaired quick and convenient after shaking.
Its design principle of the utility model can be summarized as limiting the relative displacement of superstructure and bridge pier top, on preventing
The excessive displacement of portion's structure generation and Luo Liang；The utility model simulated effect depends not only on the intensity of Antivibration block 4, Er Qieyu
The factors such as the structural type of Antivibration block 4, rigidity, Antivibration block 4 and the gap of beam body 5 are closely related；The utility model structure
Simply, easy construction, cost are low.
