Description

Bridge damping vibration-isolating device
Technical field
The utility model relates to a kind of cushion technique field, particularly a kind of damping vibration-isolating device for bridge.
Background technology
Damping vibration-isolating technology is a kind of easy, economic, advanced earthquake resistant engineering means.Damping is to utilize special cushioning members or device, and the rate in the time of macroseism that makes it is introduced into plastic zone, produces large damping, a large amount of energy that enter structural system that consume; Vibration isolation is to utilize vibration-isolating system, manages to stop seismic energy to enter agent structure.Traditional method of seismic design is guaranteed structural seismic performance by suitable selection place of the plastic hinge and design detail structure, and its essence is that the anti-seismic performance (intensity, rigidity, ductility) by strengthening structure itself is resisted geological process.But Traditional method of seismic design not only causes economy poor because material usage is excessive, also because utilizing structure itself, it carries out antidetonation, probably cause structural deterioration, therefore safety and compliance all can not be effectively guaranteed.
Utility model content
Technical problem to be solved in the utility model is: for the deficiencies in the prior art, provide a kind of simple in structure, with low cost, withstand voltage wear-resisting, the effective bridge of damping vibration-isolating damping vibration-isolating device.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of bridge damping vibration-isolating device, comprise erection support, be installed in the mandrel on erection support and be sheathed on the rubber spring group on mandrel, described rubber spring group comprises sheathed skin the first rubber spring and internal layer the second rubber spring mutually, and described the first rubber spring is the integral type rubber-metal complex spring being composited by rubber and metal spring spiral.
As to further improvement of the utility model:
Described the second rubber spring comprises small rubber spring and little metal spring, and described small rubber spring housing is located on described mandrel, and little metal spring is sheathed on small rubber spring outside.
Described mandrel is lead for retractable pencil.
Described erection support comprises upper mounting plate and lower installation board, and described lead for retractable pencil is vertically connected between upper mounting plate and lower installation board.
On described upper mounting plate and lower installation board, be evenly equipped with connecting screw hole.
Compared with prior art, the utility model has the advantage of:
Bridge of the present utility model damping vibration-isolating device, rubber and metal spring are made to integral type rubber-metal spiral complex spring, can adjust bridge construction by level of control or vertical rigidity ... the vibration period of (checking more), avoid the frequency range that seismic wave energy is larger, play the effect of vibration isolation and damping, seismic energy can dissipate; Sheathed the second rubber spring again in the first rubber spring inside, can further reduce the infringement bringing because of earthquake and vibration, and withstand voltage wear-resisting.Lead for retractable pencil structure is fairly simple, have and be out of shape very little compared with large rigidity, ... under (checking more) large seismic loading, lead for retractable pencil surrender produces the plastic strain lagging behind and consumes vibrational energy, and provide restoring force by rubber, can reduce the transmission of seismic energy to bridge, bridge be alleviated or exempt from seismic forces to damage.Have simple in structurely, withstand voltage wear-resisting, the scope of application is wide, is not subject to the advantages such as place restriction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Marginal data:
1, upper mounting plate; 2, mandrel; 3, upper junction plate; 4, little metal spring; 5, metal spring; 6, rubber; 7, small rubber spring; 8, lower connecting plate; 9, lower installation board.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of bridge of the present utility model damping vibration-isolating device, comprise erection support, be installed in the mandrel 2 on erection support and be sheathed on the rubber spring group on mandrel 2, rubber spring group comprises the first rubber spring and the second rubber spring, the first rubber spring is sheathed on the second rubber spring outside, and wherein the first rubber spring is the integral type rubber-metal complex spring being composited by rubber 6 and metal spring 5 spirals.In the present embodiment, mandrel 2 is lead for retractable pencil, and erection support comprises upper mounting plate 1 and lower installation board 9, and lead for retractable pencil is vertically connected between upper mounting plate 1 and lower installation board 9, forms I-shaped bracket, Stability Analysis of Structures.Integral type rubber-metal spiral complex spring can level of control or vertical rigidity adjust bridge construction ... the vibration period of (checking more), avoid the frequency range that seismic wave energy is larger, play the effect of vibration isolation; It has certain damping simultaneously, and seismic energy can dissipate; Lead for retractable pencil structure is fairly simple, have and be out of shape very little compared with large rigidity, ... under (checking more) large seismic loading, lead for retractable pencil surrender produces the plastic strain lagging behind and consumes vibrational energy, and provide restoring force by rubber, can reduce the transmission of seismic energy to bridge, bridge be alleviated or exempt from seismic forces to damage.
In the present embodiment, the second rubber spring comprises small rubber spring 7 and little metal spring 4, and small rubber spring 7 is sheathed on mandrel 2, and little metal spring 4 is sheathed on small rubber spring 7 outsides.A sheathed rubber spring again in the first rubber spring inside, can further reduce the infringement that earthquake and vibration bring, and withstand voltage wear-resisting.The two ends of the first rubber spring and the second rubber spring can, by upper junction plate 3 and lower connecting plate 8 structure that links into an integrated entity, make its structure more stable.
In the present embodiment, on upper mounting plate 1 and lower installation board 9, be evenly equipped with connecting screw hole, can be connected with the capital of bridge and bottom by wearing bolt, damping vibration-isolating device of the present utility model is installed in bridge, dismounting is easy to maintenance.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, all should be considered as protection domain of the present utility model.
