Utility model content
The technical problems to be solved in the utility model is: the special shock isolating pedestal of existing track bridge is improved, provide a kind of simple in structure, hard and soft having both and the economical and practical special shock isolating pedestal of Light Railway Bridge, the deficiency existing to overcome it.
For solving above-mentioned technical problem, the technical scheme that the utility model is taked is: the special shock isolating pedestal of a kind of Light Railway Bridge, comprise shock isolating pedestal core body and connected upper and lower junction steel plate, the width of the lateral of described upper junction steel plate is greater than the width of lower junction steel plate, on Kuan Chu position, upper junction steel plate both sides, is symmetrically installed with shear;
Described lower junction steel plate or form or formed by steel sheet and auxiliary steel plate bar by steel plate, described auxiliary steel plate bar is connected to the both sides that lower junction steel plate is corresponding with shear;
Described shear is made up of n piece fixed head and n-1 piece shear plate, and described n-1 piece shear plate is arranged between n piece fixed head by shear pin is alternate, described fixed head be connected by screw upper junction steel plate wide go out below position;
Gap d between the outer face of the facade of described shear plate and lower junction steel plate is 1mm, the level height of shear plate lower end or the upper level lower than lower junction steel plate, or lower than the upper level of assisting a ruler in governing a country steel plate bar being connected with lower junction steel plate;
The value of said n is the arbitrary integer between 1～100, and concrete numerical value is determined according to bearing horizontal force and shear pin diameter.
Its further technical scheme is: described fixed plate structure is identical, which is provided with pin-and-hole and interior hexagonal screw, described shear plate structure is identical, wherein one side is vertical elevation, the installation end of described shear plate is provided with pin-and-hole, when n-1 piece shear plate and n piece fixed head assemble, the vertical elevation of shear plate is positioned at the same face towards bearing core body.
Its further technical scheme be: described lower junction steel plate is made up of steel plate, and the level height of the shear plate lower end of described shear is lower than the upper level of lower junction steel plate.
Its another further technical scheme is: described lower junction steel plate is made up of steel sheet and auxiliary steel plate bar, described auxiliary steel plate 6 is connected to the upper surface of the both sides that lower junction steel plate is corresponding with shear, and the level height of the shear plate lower end of described shear is lower than the upper level of assisting a ruler in governing a country steel plate bar.
Owing to taking above technical scheme, the special shock isolating pedestal of Light Railway Bridge of the utility model has following beneficial effect:
1. because the special shock isolating pedestal of Light Railway Bridge of the utility model has been widened upper junction steel plate, and at the position of widening, shear is installed, the facade of the shear plate of shear is spacing to lower junction steel plate, shear plate only has the distance of 1mm apart from lower junction steel plate, can improve and when bearing is normally operated, obtain horizontal rigidity, and structural measure discharges in the time that bearing is subject to larger external force (seismic forces), the now special shock isolating pedestal performance of track bridge damping power consumption effect, reach the object of protection bridge security, calculate and experimental results show that by theory, before ratio, simple lateral Displacement plate reaches better effect.
2, because the special shock isolating pedestal of Light Railway Bridge of the utility model is connected with auxiliary steel plate bar on lower outside junction steel plate, thereby can reduce the height of shear plate and the thickness of lower junction steel plate, cut off when shear pin is stressed, can ensure that shear plate is turned to the position of minimum point time (the B point in accompanying drawing), still maintain a certain distance with the horizontal plane of bearing pad stone, do not produce interference, thereby ensure the normal running of bearing.
3. the shear that the special shock isolating pedestal of the Light Railway Bridge of the utility model is set up is simple in structure, easy for installation, economical and practical.
The technical characterictic of the special shock isolating pedestal of Light Railway Bridge below in conjunction with drawings and Examples to the utility model is further described.
