Problems solved by technology

Its shortcoming is that the above-mentioned device can achieve axial support and axial shock absorption, but when an earthquake occurs, there is often a radial force transmitted from the pier to the bridge, and the above-mentioned device cannot block the transmission of radial force

Embodiment Construction

[0014] Such as figure 1 As stated above, it is a bridge damping support, which includes an elastic rubber column 3 vertically arranged between the bridge pier 1 and the bottom surface of the bridge 2. One end of the elastic rubber column 3 is in contact with the upper end surface of the bridge pier 1, and the other end is in contact with On the underside of the boss on the bottom of the bridge 2, there is also a connection mechanism 4 for fixing one end of the elastic rubber column 3 on the pier 1 and fixing the other end of the elastic rubber column 3 on the boss of the bottom surface of the bridge 2. The connection mechanism 4 includes Two nylon sleeves 401 and at least three hoops 402, the nylon sleeve 401 includes a thick neck sleeve 403 sleeved on the outer peripheral surface of the bridge pier 1 or the outer peripheral surface of the bottom boss of the bridge 2 and a thin neck sleeve sleeved on the elastic rubber column 3 Sleeve 404, the thick neck sleeve 403 sleeved on ...

Abstract

The invention relates to a bridge damping bearing. The device includes an elastic rubber column and a connection mechanism. The connection mechanism includes two nylon sleeves and at least three hoops. The nylon sleeve includes a thick neck sleeve and a thin neck sleeve, and the thick neck sleeve is sleeved on the outer peripheral surface of the boss on the bottom of the bridge. The sleeve is fixed on the boss on the bottom surface of the bridge through the hoop, the thick neck sleeve sleeved on the outer peripheral surface of the pier is fixed on the pier through the hoop, and the free ends of the two thin neck sleeves sleeved on the elastic rubber column are in the middle of the elastic rubber column The overlapping arrangement forms a double-layer structure, and the double-layer structure is fixed on the elastic rubber column through hoops, and each hoop makes the nylon sleeve in a tight state. Due to the existence of the nylon sleeve, the thin neck sleeve increases the strength of the elastic rubber column to prevent the elastic rubber column from being damaged due to radial expansion under pressure. The edge collapses under pressure, and the hoop cooperates with the nylon sleeve, so that the elastic rubber column is flexibly connected with the pier and bridge, and blocks the transmission of radial force.

Description

technical field [0001] The invention relates to the technical field of bridge damping bearings, in particular to a bridge damping bearing. Background technique [0002] The existing Chinese patent database discloses a patent for a bridge shock absorber. The patent application number is CN201810574932.5, and the application date is 2018.06.06. The application publication number is CN108797325A, and the application publication date is 2018.11.13. Including a lower support plate, the top surface of the lower support plate is provided with a guide column, a support spring, a boss, an annular groove, and a baffle, the guide column is arranged around the lower support plate, and the support spring is sleeved on the guide column On the top, the boss is located at the center of the lower support plate, the top of the boss is provided with an annular groove, and the baffle is arranged outside the annular groove; on the upper support plate, there are guide post holes, grooves, The co...
