The novel bridge shock isolation and absorption soft steel damping device of the structure has the advantages of simple structure, low manufacturing cost, high adaptability, convenience in replacement after earthquake and capability of preventing a bridge floor from falling off a bridge in an earthquake.
Description
Technical field
The invention belongs to civil engineering antidetonation and damping field, relate in particular to a kind of novel bridge every damping mild metal damper.
Background technology
Be the means that structural seismic is conventional every glissando, wherein one of key technology is exactly to realize the effect of energy-dissipating and shock-absorbing by damping unit.In prior art, what be applied to bridge is generally plumbous rubber bearing, rubber bearing and mild metal damper etc. every damping damping unit.
But lead has easily environment and human body is polluted to injury, fusing point compared with low and cause the shortcoming such as unstable of dynamic property; And rubber energy dissipation capacity is comparatively low, even if also easily cause the high cycle fatigue of the attached design such as lamppost, identification post of bridge under the dynamic loading such as vehicle-mounted, the hydraulic performance decline that ageing of rubber causes simultaneously is also applied and has been brought future trouble for antidetonation; Current existing mild metal damper is large multi-form single, requirement when cannot meeting little shake, middle shake simultaneously and shaking greatly, many mild metal dampers only work under large shake, just surrender power consumption while having some little shakes, also can reach the requirement of large shake power consumption while shake greatly, but this class mild steel damper often the rigidity of additional structure is larger, and then cause the increase of geological process, while also having some little shakes, just enter plastic strain, just all change in advance thereby cause not experiencing large shake, economy is poor.
Summary of the invention
The object of the invention is to overcome the problem of above-mentioned prior art, provide a kind of novel bridge every damping mild metal damper, it is simple in structure, manufacturing cost is lower, and adaptable, it is convenient to change after shake, can prevent the bridge floor bridge phenomenon that falls simultaneously in earthquake.
The object of the invention is to be achieved through the following technical solutions:
A kind of novel bridge is every damping mild metal damper, comprise: the damping frame of the force-guided stem of long strip type, the guide cylinder of rectangular cartridge type, two fixed heads and " H " type, the two ends of the fixing described guide cylinder of described fixed head clamping, described force-guided stem is horizontally disposed with, and vertically connect any two parallel wall surfaces of described guide cylinder, described damping frame is arranged on guide cylinder inside, and its one end is fixedly connected with fixed head, and the other end is fixedly connected with force-guided stem.
Described force-guided stem is not to the distance of two fixed heads etc.
Described damping frame one end be welded to connect away from the fixed head of described force-guided stem, the other end and force-guided stem are welded to connect.
The two ends of described fixed head and guide cylinder are welded to connect.
Described guide cylinder and fixed head are No. 45 steel, and damping frame is mild steel.
Novel bridge of the present invention has the following advantages every damping mild metal damper tool: by providing a kind of novel bridge every damping mild metal damper, comprise: the damping frame of the force-guided stem of long strip type, the guide cylinder of rectangular cartridge type, two fixed heads and " H " type, the two ends of the fixing described guide cylinder of described fixed head clamping, described force-guided stem is horizontally disposed with, and vertically connect any two parallel wall surfaces of described guide cylinder, described damping frame is arranged on guide cylinder inside, its one end is fixedly connected with fixed head, and the other end is fixedly connected with force-guided stem.The novel bridge of this structure is every damping mild metal damper, and it is simple in structure, and manufacturing cost is lower, and adaptable, and it is convenient after shake, to change, and has prevented the bridge floor bridge phenomenon that falls in earthquake simultaneously.

Detailed description of the invention
As shown in Figure 1, Fig. 1 is the structural representation that a kind of novel bridge of the present invention is applied in bridge every damping mild metal damper.Bridge 200 comprises abutment 21, two fixed bearings 22 and bridge floors 23, and described bridge floor 23 both sides are provided with two and lead power block 24.A kind of novel bridge is every damping mild metal damper 100, and it is arranged on bridge floor 23 belows, and the supporting 22 that is fixed grips.
In conjunction with shown in Fig. 2 to Fig. 6, a kind of novel bridge described in the embodiment of the present invention is every damping mild metal damper 100, comprise: the damping frame 40 of guide cylinder 20, two fixed heads 30 and " H " type of the force-guided stem 10 of long strip type, rectangular cartridge type, described fixed head 30, grip the two ends of described guide cylinder 20, described force-guided stem 10 is horizontally disposed with, and vertically connect any two parallel wall surfaces of described guide cylinder 20, described damping frame 40 is arranged on guide cylinder 20 inside, its one end is fixedly connected with fixed head 30, and the other end is fixedly connected with force-guided stem 10.
The distance of described force-guided stem 10 to two fixed heads 30 is not etc.
Described damping frame 40 one end be welded to connect away from the fixed head 30 of described force-guided stem 10, the other end and force-guided stem 10 are welded to connect.
Described fixed head 30 is welded to connect with the two ends of guide cylinder 20.
Described guide cylinder 20 is No. 45 steel with fixed head 30, and damping frame 40 is mild steel.
In the time there is earthquake, bridge 200 is subject to horizontal direction seismic forces, causes rocking of bridge 200, now horizontal direction seismic forces is by the power of the leading block 24 on bridge floor 23 both sides, be passed to force-guided stem 10, be finally passed to the damping frame 40 being connected with force-guided stem 10, thereby play the effect every damping.The effect of guide cylinder 20 is to have prevented that on the one hand damping frame 40 is bearing in horizontal direction seismic forces process, the side that the moment of flexure causing because of horizontal force causes is under pressure, opposite side under tension and disrepair phenomenon occurs, the face that has prevented on the other hand damping frame 40 is outer stressed, prevents the bridge floor 23 bridge phenomenon that falls in earthquake simultaneously.
The foregoing is only explanation embodiments of the present invention; be not limited to the present invention, for a person skilled in the art, within the spirit and principles in the present invention all; any amendment of doing, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
