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 the damping mild metal damper.
Background technology
Be structural seismic means commonly used every glissando, wherein one of key technology is exactly the effect by damping unit realization energy-dissipating and shock-absorbing.In the prior art, what be applied to bridge is generally plumbous rubber bearing, rubber bearing and mild metal damper etc. every the damping damping unit.
Yet, lead have easily to environment and human body pollute injury, fusing point is lower and cause the shortcoming such as unstable of dynamic property; And the rubber energy dissipation capacity is comparatively low, even also easily cause the high cycle fatigue of the attached designs such as lamppost, identification post of bridge under the dynamic loading such as vehicle-mounted, the hydraulic performance decline that causes of ageing of rubber has also brought future trouble for the antidetonation application simultaneously; Present existing mild metal damper is large multi-form single, can't satisfy simultaneously little shake, middle shake and the requirement when shaking greatly, many mild metal dampers only work under large shake, just surrender power consumption when some then little shakes are arranged also can reach the requirement of large shake power consumption when shaking greatly, but this class mild steel damper often the rigidity of additional structure is larger, and then cause the increase of geological process, just enter plastic strain when also having some then little shakes, just all change in advance thereby cause not experiencing large shake, economy is relatively 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 the damping mild metal damper, it is simple in structure, manufacturing cost is lower, and adaptable, it is convenient to change after the shake, can prevent the bridge floor bridge phenomenon that falls in earthquake simultaneously.
The objective of the invention is to be achieved through the following technical solutions:
A kind of novel bridge is every the 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 the one end is fixedly connected with fixed head, and the other end is fixedly connected with force-guided stem.
Described force-guided stem does not wait to the distance of two fixed heads.
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 following advantage every the damping mild metal damper: by providing a kind of novel bridge every the 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, the 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 the damping mild metal damper, and it is simple in structure, and manufacturing cost is lower, and adaptable, and it is convenient to change after the shake, has prevented simultaneously the bridge floor bridge phenomenon that falls in earthquake.

The specific embodiment
As shown in Figure 1, Fig. 1 is the structural representation that a kind of novel bridge of the present invention is used in bridge every the damping mild metal damper.Bridge 200 comprises abutment 21, two fixed bearings 22 and bridge floor 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.
Extremely shown in Figure 6 in conjunction with Fig. 2, the described a kind of novel bridge of the embodiment of the invention is every damping mild metal damper 100, comprise: the damping frame 40 of the guide cylinder 20 of the force-guided stem 10 of long strip type, rectangular cartridge type, two fixed heads 30 and " H " 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, the 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 does not wait.
Described damping frame 40 1 ends 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.
When earthquake occurs when, bridge 200 be subject to level to seismic forces, cause rocking of bridge 200, this moment level to the lead power block 24 of seismic forces by bridge floor 23 both sides, be passed to force-guided stem 10, finally be passed to the damping frame 40 that is connected with force-guided stem 10, thereby play the effect every damping.The effect of guide cylinder 20 be on the one hand prevented damping frame 40 the level of bearing to the seismic forces process in, the side that the moment of flexure that causes 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 simultaneously the bridge floor 23 bridge phenomenon that falls in earthquake.
The above only is the 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 modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
