Between every two groups of steel plate layers 22, shock-absorbing springs 24 are uniformly and fixedly arranged in an annular array. In the center of the top of the steel plate layer 22, a first through hole is formed through. On the top of the steel plate layer 22, second through holes are uniformly formed through in an annular array. A second elastic limiting column 23 is fixedly arranged in the first through hole, and a first elastic limiting column 21 is fixedly arranged in the second through hole. The plate rubber bearing is composed of the rubber layer 2 and multiple groups of steel plate layers 22. Through the first elastic limiting column 21 and the second elastic limiting column 23, the connection between the steel plate layer 22 and the rubber layer 2 can be strengthened, so that it has the effect of being able to bear horizontal pulling force. When the plate rubber bearing is vibrated, the shock-absorbing springs 24 absorb the vibration, and the rubber layer 2, the first elastic limiting column 21 and the second elastic limiting column 23 weaken its rebound potential energy, so that the plate rubber bearing has good shock-absorbing performance. The shock-absorbing springs 24 distributed in an annular array are located on the outer ring of the second elastic limiting column 23, and the first elastic limiting columns 21 distributed in an annular array are located on the outer ring of the shock-absorbing springs 24 distributed in an annular array. The tops of the second elastic limiting column 23 and the first elastic limiting column 21 penetrate through the top of the uppermost steel plate layer 22 among the multiple groups of steel plate layers 22 inside the rubber layer 2, and the bottoms of the second elastic limiting column 23 and the first elastic limiting column 21 penetrate through the bottom of the lowermost steel plate layer 22 among the multiple groups of steel plate layers 22 inside the rubber layer 2. An upper support plate 1 is placed on the top of the rubber layer 2, and a lower support plate 11 is placed on the bottom of the rubber layer 2. A first groove is formed in the bottom of the upper support plate 1, and a second groove is formed in the top of the lower support plate 11. Fixing holes 14 are formed through the tops of both the upper support plate 1 and the lower support plate 11. An upper limiting ring 12 is fixedly arranged at the bottom of the upper support plate 1, and a lower limiting ring 13 is fixedly arranged at the top of the lower support plate 11.

When the plate rubber bearing is subjected to a horizontal pulling force, the upper limit ring 12 and the lower limit ring 13 can prevent the separation of its connection with the upper support plate 1 and the lower support plate 11. The connection between the steel plate layer 22 and the rubber layer 2 can be strengthened through the first elastic limit column 21 and the second elastic limit column 23, thereby enabling it to have the effect of bearing a horizontal pulling force.
