Technical field
This utility model relates to a kind of height-adjustable shock-absorption basin-type rubber support, is mainly used in earthquake prone areas and ground
On the highway sunk and railroad bridge.
Background technology
Along with the development of bridge technology, the kind of bearing have also been obtained the biggest development, creates Anti-seismic bearing, heightens
Type bearing, and the modern times are for the performance requirement of bearing, are not only on the one hand, need the combination of several functions, height-adjustable to subtract
Shake rubber support arises at the historic moment.The present inventor is by research Anti-seismic bearing, the kind of height-adjustment type bearing and performance, in conjunction with concrete
The needs of practice of construction, devise a kind of height-adjustable shock-absorption basin-type rubber support.
Utility model content
The purpose of this utility model is to provide a kind of height-adjustable shock-absorption basin-type rubber support, the damping of this bearing collection, damping and
Height regulating function is integrated, it is adaptable to infrastructure differential settlement or have the bridge of the earthquake-prone region heightening requirement to build fulcrum
If engineering region, improve the adaptability to changes of bridge.
This utility model the technical scheme is that for realizing goal of the invention
A kind of heightening shock absorbing pot rubber bearing, including corrosion resistant plate, polyfluortetraethylene plate, upper bracket plate, guide frame,
Pedestal, damped ring, lower support plate, plug, filling channel, sealing ring, pressure-bearing rubber slab, guard pin, middle steel liner plate, key exists
Between middle steel liner plate and pedestal, guard pin is set as protection mechanism.Introduce pedestal, fluted on pedestal, polytetrafluoro
Vinyl plate is embedded in the inside and forms friction pair with corrosion resistant plate.
This utility model integrates damping, damping, height regulating function, it is adaptable to infrastructure differential settlement or to
Point has the bridge construction engineering region of the earthquake-prone region heightening requirement, improves the adaptability to changes of bridge.
Below in conjunction with the accompanying drawings this utility model is described in detail.

Detailed description of the invention
A kind of height-adjustable shock-absorption basin-type rubber support, Fig. 1 include 1 corrosion resistant plate, 2 polyfluortetraethylene plates, 3 upper bracket plates, 4
Guide frame, 5 pedestals, 6 damped rings, 7 lower support plate, 8 plugs, 9 filling channels, 10 sealing rings, 11 pressure-bearing rubber slabs, 12 protections
Pin, 13 middle steel liner plates, it it is critical only that the guard pin between middle steel liner plate and pedestal.
Described filling channel 9 end need to arrange plug 8.
Described guard pin 12 is embedded in middle steel liner plate 13 and pedestal 5, guard pin 12 regular array in annular direction,
The length of guard pin 12 is depending on the thickness of middle steel liner plate, not less than 3/4ths of its thickness.Guard pin 12 radius according to
The antidetonation rank of designed bridge determines, guard pin radius value 5mm, 8mm, 10mm, 12mm, 15mm, 20mm, 30mm.
Described guiding mechanism 4 includes blade fin and guides corrosion resistant plate.
The described rubber by filling channel 9 pressure injection is silicone rubber or polyurethane rubber.
Fig. 2 is one-way movable support, including 1 corrosion resistant plate, 2 polyfluortetraethylene plates, 3 upper bracket plates, 5 pedestals, 6 dampings
Circle, 7 lower support plate, 8 plugs, 9 filling channels, 10 sealing rings, 11 pressure-bearing rubber slabs, 12 guard pins, 13 middle steel liner plates.
This kind of height-adjustable shock-absorption basin-type rubber support when bearing is installed owing to utilizing when a variety of causes and the body of a bridge have gap
Pressure injection equipment realizes the stepless speed regulation of bearing by the filling channel 9 specific rubber of pressure injection, adapts to the peace of various operating mode undersetting
Dress.
This kind of height-adjustable shock-absorption basin-type rubber support is when occurring without earthquake, and guard pin 12 connects middle steel lining 13 plate and base
Seat 5 is an entirety, pressure-bearing rubber slab pressure-bearing 11, and polyfluortetraethylene plate 2 slides with corrosion resistant plate 1 and meets displacement request.
This kind of height-adjustable shock-absorption basin-type rubber support is when earthquake occurs, owing to the active force guard pin 12 of earthquake is cut
Disconnected, pedestal 5 occurs to slide with middle steel liner plate 13 and consumes part energy, and damped ring 6 stress plays damping action, inhales further
The energy receiving earthquake realizes the effect of damping shock absorption.
This kind of height-adjustable shock-absorption basin-type rubber support integrates to be heightened, damps and shock-absorbing function, expands this kind of bearing
Range of application, particularly ground easily sinks and earthquake takes place frequently area.
