Problems solved by technology

[0004] In order to be able to absorb the vibration on the highway bridge and activate the buffering effect, it is usually necessary to install a buffering device on the bridge support. However, the structure of the traditional buffering device is too simple and lacks mutual auxiliary shock absorbing devices. Once damaged, the buffering effect suddenly disappears. , the danger of highway bridges has risen sharply, and even induced safety accidents

Embodiment 1

[0025] see Figure 1~2 , a highway bridge shock-absorbing bracket, comprising a bridge plate 1, a support column 2 and a concrete base 3, the bottom end of the support column 2 is provided with a concrete base 3, and the center of the top of the support column 2 is provided with a shock-absorbing boss 9, The center of the top of the support column 2 is evenly provided with some shock-absorbing holes 4 matched with the shock-absorbing boss 9, the top of the shock-absorbing hole 4 connects with the shock-absorbing boss 9, and the shock-absorbing hole 4 is provided with a shock-absorbing The rod 5, the shock absorbing hole 4 and the shock absorbing rod 5 are slidingly connected, the bottom end of the shock absorbing rod 5 is provided with a first spring 6 matched with the shock absorbing hole 4, and the top of the shock absorbing rod 5 is provided with a support plate 7. The top of the support plate 7 is provided with a shock absorbing plate 8, and the top of the described shock ...

Embodiment 2

[0027] This embodiment is further elaborated on the basis of Embodiment 1. The outer end of the shock-absorbing boss 9 is covered with a second spring 10 matched with the support plate 7, and the top end of the second spring 10 is fixedly connected to the The top of the support plate 7, the outer cover of the second spring 10 is provided with a protective cover 11, the protective cover 11 is a shrinkable sleeve, the top of the protective cover 11 is fixedly connected to the top of the support plate 7, and the bottom of the protective cover 11 The end is fixedly connected to the top of the support column 2, and through the mutual cooperation of the second spring 10 and the shock-absorbing boss 9, the shock-absorbing and shock-absorbing effects of the shock-absorbing plate 8 and the first spring 6 are further assisted, and multiple groups of effective shock-absorbing The combination of devices and mutual cooperation greatly improve the shock absorption effect, and can effectively...

Embodiment 3

[0030] This embodiment is further elaborated on the basis of Embodiment 1. The middle part of the left and right side ends of the support column 2 is provided with a side cavity 12, and the side cavity 12 is connected with a shock-absorbing hole 13, and the shock-absorbing hole 13 is connected to the side cavity. 12 seem to be perpendicular to each other, and the shock-absorbing hole 13 and the support column 2 are parallel to each other. The shock-absorbing hole 13 is provided with a shock-absorbing rod 14, which is slidingly connected between the shock-absorbing hole 13 and the shock-absorbing rod 14.

Abstract

The invention discloses a damping bracket of a highway bridge. The damping bracket comprises a bridge plate, a supporting column and a concrete base, the concrete base is arranged at the bottom end ofthe supporting column, and a damping boss is arranged in the center of the top end of the supporting column; several damping holes cooperating with the damping boss are uniformly formed in the centerof the top end of the supporting column, the top ends of the damping holes are in through connection with the damping boss, and damping rods are arranged in the damping holes; first springs cooperating with the damping holes are arranged at the bottom ends of the damping rods, a supporting plate is arranged at the top ends of the damping rods, a damping plate is arranged at the top end of the supporting plate, and a bridge plate is arranged at the top end of the damping plate; vibration on the highway bridge is transmitted downward through the bridge plate, primary damping is conducted through the damping plate, after damping, remaining waves are subjected to secondary damping through the damping rods and first springs, the damping effect is greatly improved, and the vibration on the highway bridge can be effectively absorbed and weakened; second springs cooperate with the damping boss, and the vibration absorbing and damping effects of the damping plate and the first springs are further improved.

Description

technical field [0001] The invention relates to the technical field of highway bridges, in particular to a vibration-damping support for highway bridges. Background technique [0002] Highway and bridge engineering refers to the planning, design, construction, maintenance, and repair of structures that cross waters, valleys, and all traffic passages. [0003] Bridge bearings are important structural components connecting the bridge superstructure and substructure. It can reliably transmit the reaction force and deformation (displacement and rotation angle) of the bridge superstructure to the bridge substructure, so that the actual stress of the structure is consistent with the calculated theoretical diagram. [0004] In order to be able to absorb the vibration on the highway bridge and activate the buffering effect, it is usually necessary to install a buffering device on the bridge support. However, the structure of the traditional buffering device is too simple and lacks ...
