Abstract
The invention discloses a damping bridge structure which comprises arc-shaped elastic steel plates and energy-dissipation dampers. The tops of the arc-shaped elastic steel plates are installed inside grooves formed in a bridge body, elastic columns and high-energy springs are alternatively connected inside the arc-shaped elastic steel plates, the upper ends of the energy-dissipation dampers are connected with the bottoms of the arc-shaped elastic steel plates, the lower ends of the energy-dissipation dampers are connected with lead core rubber blocks, the lead core rubber blocks are arranged inside limiting spaces, the limiting spaces are formed in grooves of bridge piers, limiting blocks are installed at two ends of each limiting space, steel balls are installed at the bottoms of the lead core rubber blocks and the limiting spaces, and moving cavities are reserved between the lead core rubber blocks and the limiting blocks. Part of energy produced by a bridge body of the damping bridge structure in fierce shaking when an earthquake occurs is absorbed through deformation of the arc-shaped elastic steel plates, so that bridge collapse does not occur.
Description
Technical field
The invention belongs to cushion technique field, and in particular to a kind of damping bridge structure.
Background technology
Earthquake also known as earthquake, vibrate, be that vibration is caused during earth's crust quick release of energy, period can produce a kind of natural phenomena of seismic wave.Mutual extrusion and collision between plate and plate on the earth, causes edge of plate and plate interiors to produce the changing of the relative positions and rupture, is to cause earth shock（That is earthquake）Main cause.The place that earthquake takes place referred to as focus, the ground directly over focus is referred to as earthquake centre.The most strong place of the ground vibration of ruinous earthquake is referred to as meizoseismal area, meizoseismal area area often namely where earthquake centre.Earthquake often results in serious personal's injures and deaths, fire hazard, floods, toxic gas leakage, bacterium and radioactive substance diffusion, it is also possible to cause the secondary disasters such as tsunami, landslide, avalanche, ground fissure.China is the multiple country of an earthquake, and each macroseism is nearly all with the disaster examples of bridge.The disabler of bridge often causes to be difficult to the destruction recovered within the time of end to traffic system, not only brings huge loss to national economy, also brings many difficulties to the earthquake relief work work after shake.The damping effect of current damping bridge structure is not fine, general is exactly installation block rubber and the spring between pontic and bridge pier, the effect of damping is very limited, and earthquake is not only vertical energy wave, also along with transverse energy ripple sidewards, and current damping bridge structure rarely has in the problem that transverse energy ripple causes bridge off normal and is related to.
The content of the invention
It is an object of the invention to provide a kind of damping bridge structure, to solve the problems, such as to be proposed in above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of damping bridge structure, including arc elastic steel plate and energy-consumption damper, the top of the arc elastic steel plate is arranged on the inside grooves of bridge body, the inside of the arc elastic steel plate is alternately connected with resilient stud and high energy spring, the upper end of the energy-consumption damper is connected with the bottom of arc elastic steel plate, the lower end of the energy-consumption damper is connected with lead-rubber block, the lead-rubber block is arranged on the inside of spacing cavity, the spacing cavity is arranged on the inside grooves on bridge pier, the two ends of the spacing cavity are provided with limited block, the lead-rubber block is provided with steel ball with the bottom of spacing cavity, mobile cavity is reserved between the lead-rubber block and limited block.
Preferably, the resilient stud and high energy spring are disposed as 4-6 roots, and the two is alternately connected to the inside of arc elastic steel plate.
Preferably, energy-consumption damper is set to 4, and is equidistantly connected between flexible arc steel plate and spacing cavity with being spaced.
Technique effect of the invention and advantage：The damping bridge structure is arranged on the inside grooves of bridge main body by the top of arc elastic steel plate, the inside of arc elastic steel plate is alternately connected with resilient stud and high energy spring, when earthquake occurs, the energy that bridge body is produced when acutely shake is produced absorbs the energy of part by arc elastic steel plate deformed, resilient stud can support arc elastic steel plate simultaneously, it is unlikely to bridge span to collapse, remaining energy provides the resistance for moving to consume by energy-consumption damper；Because the two ends of spacing cavity are provided with limited block, lead-rubber block is provided with steel ball with the bottom of spacing cavity, mobile cavity is reserved between lead-rubber block and limited block, when earthquake produces transverse energy ripple to cause bridge lateral to move, lead-rubber block is driven to be moved left and right in mobile cavity by steel ball, it is to avoid the accident of the bridge collapse caused by transverse energy ripple occur.
