Problems solved by technology

Due to the problem of the bridge's own structure, it is difficult to reduce the vibration amplitude on the material of the bridge. In order to solve this technical problem, the only way to reduce vibration is to install a vibration-damping bearing at the bridge connection. Therefore, a bridge vibration-reducing support

Embodiment Construction

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0020] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative relationship between the various components in a certain posture (as shown in the accompanying drawings). When the positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

Abstract

The invention relates to the technical field of bridge structures, in particular to a bridge vibration-damping support. The bridge vibration-damping support comprises an upper seat plate, a lower seatplate, an upper buffer seat disposed at the bottom of the upper seat plate and a lower buffer seat disposed on the lower seat plate. The bottom surface of the upper buffer seat is a convex surface, and the top of the lower buffer seat is a concave surface matched with the convex surface of the bottom of the upper buffer seat. Multiple spherical grooves are formed in the convex surface of the upper buffer seat and arranged in parallel along the convex surface. Arc-shaped grooves matched with the parallel spherical grooves are formed in the concave surface of the lower buffer seat. Steel ballsare disposed between the spherical grooves and the arc-shaped grooves. The lower seat plate is in the shape of U, first steel pipes are fixedly and symmetrically disposed at the U-shaped edge, the first steel pipes are internally provided with first springs, and one ends of the first springs are fixed to the inner edge of the lower seat plate. The bridge vibration-damping support is simple in structure, when a bridge is subjected to great pressure and horizontal and longitudinal vibrations are caused, horizontal and longitudinal damping is formed by the cooperation of components, and thereforethe vibrations of the bridge are reduced.

Description

technical field [0001] The invention relates to the technical field of bridge structures, in particular to a bridge damping support. Background technique [0002] In today's construction field, especially in the field of road construction, bridges are the most important. Under the action of external vibration, the bridge will cause its own vibration. This vibration often leads to damage to the bridge structure. Over time, this damage will directly affect the safety and service life of the bridge. Due to the problem of the bridge's own structure, it is difficult to reduce the vibration amplitude on the material of the bridge. In order to solve this technical problem, the only way to reduce vibration is to install a vibration-damping bearing at the bridge connection. Therefore, a bridge vibration-reducing support. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides a bridge damping bearing. ...
