Abstract
The present invention discloses a kind of novel bridge damper structure, the structure includes that multi partition damper is rectangular parallelepiped structure, it is arranged inside bridge deck structure, one layer of metal of tiling or nonmetallic particle swarm in each subregion cavity of damper, inside cavity have one layer of padded coaming.The advantage of the invention is that：The characteristics of thermal energy that the novel bridge damper structure of proposition loses by damper converts the vibration kinetic energy of floorings to damper internal particle effective collision, to make floorings obtain more efficiently effectiveness in vibration suppression.
Description
Technical field
The present invention relates to technical field of civil engineering, and in particular to a kind of novel bridge damper structure.
Background technology
Bridge is with its span ability is strong and the application of the advantages in engineering such as space availability ratio height is very extensive, and vehicle is in bridge
Traveling can make bridge that low-frequency vibration occur on beam, and then will produce low-frequency noise, this can not only reduce the durability of bridge structure,
Also the life to bridge subjective reflection brings puzzlement.
In a practical situation, existing bridge vibration reducing measure has uses vibration isolation rubber bearing at bridge pad, but rubber
Glue bearing can only reduce the vibration of bridge pier structure, and can aggravate the vibration of bridge superstructure.Thus need one kind can
Reduce the damper structure of bridge superstructure vibration.
Invention content
Invention is designed to provide a kind of novel bridge damper structure, with overcome the deficiencies in the prior art, especially
It is to reduce bridge superstructure vibration, reduces the performance in terms of floorings low-frequency noise.
The purpose of the present invention can be realized by following technical proposals：
A kind of novel bridge damper, the structure include that multi partition damper is rectangular parallelepiped structure, are arranged in bridge floor
Inside configuration, each subregion cavity of damper one layer of metal of interior tiling or nonmetallic particle swarm, inside cavity have
One layer of padded coaming.
As preferred design scheme, the multi partition damper includes damper cavity, particle swarm, fender
Material and for subregion metallic spring.
As preferred design scheme, projected area of the particle swarm in intracavitary subregion on horizontal plane is subregion bottom
40%-the 60% of area.
As preferred design scheme, the particle swarm is by several a diameter of 2-10mm metals or nonmetallic circular granular
Composition.
As preferred design scheme, the damper intracavitary padded coaming uses high damping visco-elastic material.
As preferred design scheme, the metallic spring for subregion uses elastomeric sheet metal.
As preferred design scheme, the multi partition damper is embedded in inside floorings.
The advantage of the invention is that：
（1）The novel bridge damper of use can give full play to the characteristic of damper energy consumption.
（3）Intergranular effective collision can effectively be increased using the different particle swarm of size.
（4）The vibration of track plates can effectively be passed to damper endoparticle by the elastomeric sheet metal used
Group.
（5）The high damping visco-elastic material of use can effectively weaken the kinetic energy of particle swarm as padded coaming.

Specific implementation mode
It elaborates in conjunction with the accompanying drawings and embodiments to the present invention, embodiment described below is the part of the present invention
Embodiment.On the basis of the embodiment of the present invention, those skilled in the art are not making other creative works under the premise of institute
The embodiment obtained is all within the scope of protection of the invention.
Embodiment：
As shown in Figs. 1-3, an embodiment of the present invention provides a kind of novel bridge damper structure, which includes multi partition
Damper 100 is rectangular parallelepiped structure, is arranged in 200 inside configuration of bridge floor, 100 each subregion cavity of damper and puts down
One layer of metal or nonmetallic particle swarm 110 are spread, inside cavity has one layer of padded coaming 120.
As shown in Figs. 1-3,100 structure setting of multi partition damper of the present invention hinders vibration damping inside floorings 200
Buddhist nun's device 100 is spaced in 200 intermediate double amber lines 220 of both sides pavement position 210 and floorings respectively along floorings 200 are longitudinal
The arrangement of one determining deviation is laid, and metallic spring 130 of 100 inside configuration of damper for subregion is relatively small using rigidity
Steel bomb piece, damper 100 can be vertically divided into along track plates by the areas Liang Ge according to the size of track plates vertical direction spatial.
As shown in figure 4, damper 100 is embedded into 200 structure of bridge panel and connects with 200 structural rigidity of bridge panel
It connects.
The construction procedure of the utility model vibration and noise reducing track plates is as follows：
（1）It is laid with deck structrue 200, and longitudinal respectively in both sides pavement position 210 and floorings 200 in floorings 200
It is spaced in intervals in intermediate double amber lines 220 and the cuboid bathtub construction more bigger than damper 100 is arranged.
（2）Multi partition damper 100 is made, pasting one layer in 100 cavity inner wall of damper uses rubber system
The padded coaming 120 of work uses 130 steel bomb piece of metallic spring as the partition board for subregion, 130 steel bomb piece water of metallic spring
It is flat to be arranged in the centre position of 100 cavity of damper.
（3）By a diameter of 2-10mm metals or nonmetallic circular granular 110 according in the horizontal plane in each subregion of intracavitary
Projected area be 52% being laid for each subregion floor space.
Multi partition damper 100 is placed in 200 cuboid empty slot of floorings and is fixed.
