Abstract
The invention discloses a height-adjustable damping pot-type rubber support. The height-adjustable damping pot-type rubber support comprises a stainless steel plate, a polytetrafluoroethylene plate, an upper support plate, a guide structure, a base, a damping ring, a lower support plate, a screwed plug, a filling channel, a sealing ring, a pressure-bearing rubber plate, protection pins and a middle steel lining plate, wherein the lower support plate is provided with the filling channel; the rubber plate is arranged in the lower support plate; the middle steel lining plate is connected with the base through the protection pins; the base is connected with the lower support plate through the damping ring; the guide mechanism is arranged between the base and the upper support plate; the base is provided with the polytetrafluoroethylene plate which constructs a friction pair together with the stainless steel plate in a contact way. According to the height-adjustable damping pot-type rubber support, stepless speed regulation of the support can be realized in a way of pressure-injecting rubber through the filling channel; under a normal condition, the protection pins can carry shearing force; the support is a normal pot-type rubber support; in the case of an earthquake, the protection pins are cut short, and the damping ring plays a role in damping.
Description
Technical field
The present invention relates to a kind of height-adjustable shock-absorption basin-type rubber support, be mainly used on highway and the railroad bridge of earthquake prone areas and setting of ground.
Background technology
Along with the development of bridge technology, the kind of bearing have also been obtained very big development, creates Anti-seismic bearing, height-adjustment type bearing, and the modern times are for the performance requirement of bearing, it is not only on the one hand, it is necessary to the combination of several functions, height-adjustable yielding rubber bearing arises at the historic moment. The present inventor is by studying Anti-seismic bearing, the kind of height-adjustment type bearing and performance, in conjunction with the needs of concrete practice of construction, devises a kind of height-adjustable shock-absorption basin-type rubber support.
Summary of the invention
It is an object of the invention to provide a kind of height-adjustable shock-absorption basin-type rubber support, this bearing integrates damping, damping and height regulating function, suitable in infrastructure differential settlement or the bridge construction engineering region that fulcrum is had the earthquake-prone region heightening requirement, improve the adaptability to changes of bridge. 2. the present invention the technical scheme is that 3. 1 kinds of heightening shock absorbing pot rubber bearings for realizing goal of the invention; 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, it is critical only that, between middle steel liner plate and pedestal, guard pin is set as protection mechanism.
The present invention integrates damping, damping, height regulating function, it is adaptable to infrastructure differential settlement or fulcrum has the bridge construction engineering region of the earthquake-prone region heightening requirement, improves the adaptability to changes of bridge.
Below in conjunction with accompanying drawing, the present invention is described in detail.
Accompanying drawing explanation
. Fig. 1 is one-way movable support structural representation. Fig. 2 is hold-down support structural representation.
In accompanying drawing, 1 corrosion resistant plate, 2 polyfluortetraethylene plates, 3 upper bracket plates, 4 guide frames, 5 pedestals, 6 damped rings, 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.
Detailed description of the invention
A kind of height-adjustable shock-absorption basin-type rubber support; Fig. 1 includes 1 corrosion resistant plate, 2 polyfluortetraethylene plates, 3 upper bracket plates, 4 guide frames, 5 pedestals, 6 damped rings, 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, and 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 with in pedestal 5, and guard pin 12 regular array in annular direction, the length of guard pin 12, depending on the thickness of middle steel liner plate, is not less than 3/4ths of its thickness. Guard pin 12 radius is determined according to the antidetonation rank of designed bridge, guard pin radius value 5mm, 8mm, 10mm, 12mm, 15mm, 20mm, 30mm.
Described guiding mechanism 4 includes blade fin and guiding 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 damped rings, 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 owing to utilizing pressure injection equipment to realize the stepless speed regulation of bearing by the filling channel 9 specific rubber of pressure injection when a variety of causes and the body of a bridge have a gap, adapts to the installation of various operating mode undersetting when bearing is installed.
This kind of height-adjustable shock-absorption basin-type rubber support is when occurring without earthquake, and it is an entirety that guard pin 12 connects middle steel lining 13 plate with pedestal 5, 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 off; pedestal 5 occurs to slide with middle steel liner plate 13 and consumes part energy, and damped ring 6 stress plays damping action, and the energy absorbing earthquake further 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 the range of application of this kind of bearing, particularly ground and easily sinks and earthquake takes place frequently area.
