Abstract
There is the bridge of shock-damping structure, comprising: the bottom girder of multiple sequential, between two adjacent bottom girders, be provided with deformation joint, being provided with at least one below each bottom girder for supporting the stub of this bottom girder; Earthquake resistant structure between bottom girder and stub, this earthquake resistant structure comprise the wearing layer being layed in stub top and contacting with bottom girder, the projection be connected with bottom girder the multiple of bottom girder soffit, on stub top and for being embedded in groove wherein, damping damping piece between projection bottom surface and groove bottom land for projection.The utility model by arranging earthquake resistant structure, bradyseism supporting component under bottom girder, thus minimizing produces the infringement of horizontal impact power to bridge because of earthquake.Deformation joint is set between two adjacent bottom girders, thus realizes decreasing the object of the miniature deformation on external vibration and length direction to the injury of bridge.
Description
Technical field
The utility model relates to a kind of bridge construction thing, especially a kind of bridge with shock-damping structure.
Background technology
In daily life, bridge construction is under the factor effect such as mobile load, variations in temperature, extraneous construction, concrete shrinkage and creep, earthquake, and all can produce distortion, especially under the impact of vibration wave, its deflection is comparatively large, and this deflection can constantly accumulation.If generation earthquake, its impact brought will be larger, create very large horizontal force and vertical force, bridge superstructure is subjected to displacement and is out of shape, when displacement exceed bridge panel on bridge pier shelve width after, bridge board will fall, now, not only bridge is damaged, and pedestrian on bridge, under bridge and vehicle all there will be serious accident.Even if great accident not yet occurs this bridge, but extraneous vibration source is also obvious to its injury, therefore needs badly and takes measures to deal with problems.
Utility model content
For the deficiencies in the prior art, the utility model aims to provide a kind of bridge with shock-damping structure, its earthquake resistant structure had by self, bradyseism supporting component, deformation joint is set between two adjacent bottom girders, reduce the bridge displacement that causes because of external vibration excessive, time serious, cause the situation of bridge collapse to occur because distortion causes that bottom girder stress is concentrated etc.
For achieving the above object, the utility model adopts following technical scheme:
There is the bridge of shock-damping structure, comprising:
The bottom girder of multiple sequential, is provided with deformation joint between two adjacent bottom girders, is provided with at least one for supporting the stub of this bottom girder below each bottom girder;
Earthquake resistant structure between bottom girder and stub, this earthquake resistant structure comprise the wearing layer being layed in stub top and contacting with bottom girder, the projection be connected with bottom girder the multiple of bottom girder soffit, on stub top and for being embedded in groove wherein, damping damping piece between projection bottom surface and groove bottom land for projection.
Preferably, this bridge with shock-damping structure also comprises and is installed on the bradyseism supporting component of bottom girder lower surface near deformation joint one end, and the bottom of bradyseism supporting component is fixedly connected with ground, and the apical support of bradyseism assembly is in bottom girder soffit.
Preferably, damping damping piece is spring or has flexible pad.
The beneficial effects of the utility model are:
Relative to prior art, the bridge with shock-damping structure described in the utility model arranges damping, bradyseism supporting component by the relevant position between its bottom girder and stub, relevant position between bottom girder and ground, and arranges deformation joint between two adjacent bottom girders.Decrease as Construction Vibration, oversize vehicle pass through that the vibration, earthquake etc. that cause produce because of extraneous vibration source from all directions, the especially vibration of horizontal direction or the infringement of distortion to bridge in a small amount.The utility model structure is simple, easily implements, has broad application prospects.

Fig. 2 is the partial view at A place in Fig. 1.
Reference numeral: 10, ground; 20, bottom girder; 201, projection; 202, wearing layer; 21, deformation joint; 30, stub; 301, groove; 302, damping damping piece; 31, bradyseism supporting component.
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the utility model is further described:
As shown in Figure 1, a kind of bridge with shock-damping structure of the utility model, comprises the multiple bottom girder 20, stub 30, the earthquake resistant structure that are arranged in order.Deformation joint 21 is provided with between two adjacent bottom girders 20, this deformation joint 21 is that the miniature deformation of two bottom girders 20 provides and dodges space, between two bottom girders 20, the gap size of deformation joint 21 must be arranged according to actual conditions, namely gap size can not be excessive or too small, if excessive, the vehicles can be affected and pass through at bridge, in addition, deformation joint 21 is excessive easily produces larger vibration when the vehicles also can be caused to cross; If too small, the containing of bottom girder 20 pairs of miniature deformations can be made less able, cause adjacent two bottom girders 20 contact and therefore produce extrusion stress.The below of each bottom girder 20 is provided with the stub 30 for supporting corresponding bottom girder 20, has at least one stub 30 below each bottom girder 20.As shown in Figure 2, earthquake resistant structure is between bottom girder 20 and stub 30, earthquake resistant structure comprises wearing layer 202, projection 201, groove 301, damping damping piece 302, wearing layer 202 is layed in stub 30 top and contacts with bottom girder 20 soffit, projection 201 is positioned at the soffit of bottom girder 20, and projection 201 is connected with bottom girder 20, groove 301 is positioned at stub 30 top, and groove 301 is for being embedded in accordingly wherein for projection 201.Damping damping piece 302 is arranged between projection 201 bottom surface and groove 301 bottom land.Enforcement like this, just can reduce extraneous vibration and cause bridge displacement to be out of shape the excessive problem causing stress to be concentrated.
In order to strengthen damping, the anti seismic efficiency of aforementioned schemes better, the bridge with shock-damping structure described in the utility model also comprises bradyseism assembly, bradyseism supporting component 31 is installed on bottom girder 20 soffit near one end of deformation joint 21, its bottom is fixedly connected with ground 10, and its apical support is in bottom girder 20 soffit.
Absorb the effect of vibration wave to strengthen earthquake resistant structure, preferably, damping damping piece 302 is for spring or have flexible pad.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
