Abstract
The utility model relates to a plate type shock-absorbing-and-insulating rubber pedestal. The utility model resolves the problem that the whole prior rubber pedestal can transversely shift until being thrown away from a pier. The upper and the lower surfaces of the board type rubber pedestal (5) are respectively provided with a steel plate (4); the steel plates (4) of the upper and the lower surfaces are respectively connected with a transitional steel plate (3); and the upper and the lower transitional steel plates (3) are respectively connected with a pre-buried steel plate (2) by a bolt (7); or the upper and the lower steel plates (4) provided with screw holes are connected with the pre-buried steel plates (2) by bolts.
Description
Technical field:
The utility model relates to and a kind of bridge pad in bridge construction field, and particularly a kind of shock insulation laminated rubber bearing that subtracts comprises that rectangle subtracts the shock insulation laminated rubber bearing and circle subtracts the shock insulation laminated rubber bearing.
Background technology:
Present laminated rubber bearing generally all directly lies against laminated rubber bearing during installation on the pier (platform), without any being connected, when normally using, bears the horizontal force of bearing by the frictional force between bearing and the pier (platform) between bearing and the pier (platform); When earthquake took place, the horizontal force moment that acts on bearing strengthened, because bearing is in the horizontal direction without any constraint, beam is known from experience and produced horizontal drift at the bearing position, and the beam body will be pulled out away from pier (platform) when serious.
The utility model content:
The purpose of this utility model provides a kind of simple in structure, and is easy for installation, can whole not produce lateral drift, can damper subtract the shock insulation laminated rubber bearing.
The utility model is achieved in that
The utility model subtracts the shock insulation laminated rubber bearing, respectively there is steel plate 4 above and below of laminated rubber bearing 5, the steel plate 4 of above and below respectively is connected with a transition steel plate 3, upper and lower transition steel plate 3 respectively is connected with pre-embedded steel slab 2 by bolt 7, has screw to be connected with pre-embedded steel slab 2 by bolt on the perhaps upper and lower steel plate 4.
Laminated rubber bearing 5 is by the steel plate 4 of above and below and the rubber layering between some horizontal sandwich clad steels and the steel plate is superimposed forms through high temperature vulcanized bonding, upper and lower steel plate 4 is connected by some bolts 6 with transition steel plate 3, and transition steel plate 3 is connected with pre-embedded steel slab 2 by sleeve bolt 7.
Laminated rubber bearing 5 is circle or the rectangle bearings that are made of circle or rectangular steel plates.
The periphery of upper and lower steel plate 4 forms the upper and lower flange of bearing, and upper and lower flange is connected with pre-embedded steel slab 2 by bolt.
The operating principle that the utility model subtracts the shock insulation laminated rubber bearing is: laminated rubber bearing is by rubber and the sandwich clad steel layering is superimposed forms through high temperature vulcanized bonding, when bearing bears vertical load, the lateral deformation of rubber layer suffers restraints, make bearing have very big vertical bearing capacity, when bearing bears horizontal loading, the relative sidesway of its rubber layer significantly reduces, and makes rubber layer can reach very big whole sidesway face and is unlikely unstability, and keep less horizontal rigidity.Because adopt bolt to be connected between whole bearing and beam body and the pier (platform), when earthquake was arrived, horizontal force passed to bearing by pier (platform), bearing is out of shape to generation in level, the absorption energy, thus the energy that makes earthquake pass to Liang Tishang significantly reduces.So this subtracts the shock insulation laminated rubber bearing is that a kind of horizontal rigidity is less, the very big ideal of horizontal sidesway admissible value subtracts every device.
The advantage that the utility model subtracts the shock insulation laminated rubber bearing is that bearing and beam body and pier (platform) connect into an integral body, when earthquake is arrived, subtract the shock insulation laminated rubber bearing and produce distortion in the horizontal direction, absorb energy, thereby keep beam body and pier (platform) not to be destroyed effectively.

The specific embodiment:
Embodiment 1:
The utility model subtracts the shock insulation laminated rubber bearing and comprises sleeve 1, pre-embedded steel slab 2, transition steel plate 3, the upper and lower steel plate 4 of bearing, rectangular plate type neoprene bearing 5, be connected the connecting bolt 6 between upper and lower steel plate 4 and the transition steel plate 3, be connected the sleeve bolt 7 between transition steel plate and the pre-embedded steel slab.Sleeve 1 is connected with beam body or pier.Rubber layering between upper and lower steel plate 4 and some horizontal steel plates and the steel plate is superimposed through the high temperature vulcanized neoprene bearing 5 that is bonded to.
Embodiment 2:
The utility model subtracts the basic structure of shock insulation laminated rubber bearing with embodiment 1, and difference is that bearing is circular laminated rubber bearing.
