Description

The special shock isolating pedestal of track bridge
Technical field
The utility model relates to track bridge technical field, particularly relates to a kind of track bridge special purpose device.
Background technology
Neoprene bearing uses maximum shock isolating pedestals in domestic bridge construction.Neoprene bearing is mainly by increasing the flexibility of bridge construction, thus the cycle of extending structure reaches the effect of damping, but, laminated rubber bases is while less bridge is subject to seismic (seismal, horizontal rigidity is too little, horizontal comparison admissible value is large, adds the relative displacement of beam body and foundation stone, is not suitable for track traffic.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency for above-mentioned technology, and the basis of original shock isolating pedestal is improved, and provides a kind of structure simple, the special shock isolating pedestal of the track bridge that cost performance is high.
Technical solution adopted in the utility model has two kinds, respectively:
Scheme one: the special shock isolating pedestal of track bridge comprises: comprise rubber base and connected upper junction steel plate and lower junction steel plate, be coated with the spacing steel plate be connected with upper junction steel plate or lower junction steel plate outside the surrounding of described rubber base.
Scheme two: the special shock isolating pedestal of track bridge, comprise rubber base and connected upper junction steel plate and lower junction steel plate, upper limit steel plate and lower limit steel plate is coated with outside the surrounding of described rubber base, described upper limit steel plate is connected with upper junction steel plate, and described lower limit steel plate is connected with lower junction steel plate.
The beneficial effects of the utility model are: 1. on the basis of original structure, add spacing steel plate, add the lateral stiffness of bearing, make displacement can allow limit scope in and excessive compressive strain can not be produced, improve earthquake time safety, alleviate structural damage.2. the special shock isolating pedestal of the track bridge of the utility model has structure simply, easy for installation, saving steel, cheap advantage, in addition, also has horizontal rigidity large, horizontal comparison admissible value is little, the feature that the relative displacement of beam body and foundation stone is little, is applicable to track traffic.
