It must not be too large here, which would have a serious effect on the passage of the vehicles on the deck. The large deformation of the beam body is greatly compressed by the mounting position and the structure of the structure B (the structure B comprises a damping rubber block, a connecting bolt, a pressure plate, a damping rubber column and the like) due to the fact that the bulk waves of various materials are larger than the space occupied by the volume of the structure B; meanwhile, the structure cannot effectively provide the generation of space catastrophic displacement between the beam body and the pier generated by the earthquake longitudinal wave.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can enough prevent that the roof beam body from falling, can prevent again that the roof beam body collides the antidetonation damping prevents falling roof beam structure.

Detailed Description
The structure and the working principle of the anti-seismic damping anti-falling beam structure provided by the invention are further described below with reference to the attached drawings and specific implementation examples.
As shown in fig. 1, constitute the structure of the anti-seismic damping anti-falling beam structure provided by the utility model comprises, the bottom is the bridge girder body 2 of salient piece 1 and the pier 4 of the recess 3 that upper portion corresponds with above-mentioned salient piece, be concave, protruding connection between the two promptly to be provided with support mechanism 5 in its junction, be provided with the rubber damper 6 that comprises the rubber tie plate in the both sides that constitute the connection lug of above-mentioned girder body, rigid connection rod mechanism 7 passes the constitution the recess and the lug of the girder body of bridge and pier, its both ends are passed through bolt 10 (or other riveted structure) and are fixed together.
The principle is that two rubber dampers are distributed on two sides of a bridge connecting lug structure, and an upper bridge structure is effectively connected with a lower bridge structure through a rigid connecting device. The rigid connecting device effectively prevents the separation of the upper bridge structure and the lower bridge structure caused by the primary waves of the earthquake when a geological disaster occurs; the two special rubber dampers effectively apply the force generated by transverse waves and surface waves brought by earthquake to the friction between the inner molecules of the rubber part through the deformation of the special rubber dampers, so that the rubber part has very large and reliable damping performance, namely the hysteresis of movement (the deformation of the rubber lags behind the stress of the rubber in the stress process). Thereby effectively protecting the bridge from being damaged. A large number of practical experiences prove that the special viscoelasticity of the rubber is utilized, so that violent internal friction is caused under the action of external force in the vibration process, reaction force is generated, kinetic energy is converted into heat energy, energy conversion is realized, and the aim of reducing the vibration amplitude is effectively fulfilled. The larger the force generated by the transverse wave and the surface wave brought by the earthquake, the larger the deformation of the special rubber damper, the larger the generated reaction force, and the more violent the internal friction, the larger the energy conversion.
In the structure that constitutes the above-mentioned antidetonation damping anti-falling beam structure:
in order to effectively restrict the transverse deformation of the rubber cushion plate and prevent the rubber cushion plate from being damaged due to excessive deformation when the rubber cushion plate part is subjected to excessive force;
the rubber cushion plate is formed by vulcanizing a rubber sheet 61 and a steel lining plate 62 which are arranged at intervals into a whole; or

And through add the reinforced steel plate on the inner structure, effectual restriction damping rubber's lateral deformation prevents because damping rubber part when receiving too big power, and the rubber part is too big to be out of shape and is suffered destruction.
The structure of the anti-seismic damping anti-falling beam structure can also be a bridge body with a groove at the bottom and a bridge pier with a lug corresponding to the groove at the upper part, namely, the bridge body and the bridge pier are connected in a concave-convex mode, a support mechanism is arranged at the joint of the bridge body and the bridge pier, rubber dampers composed of rubber base plates are arranged on two sides of the connecting lug forming the bridge pier, and the rigid connecting rod mechanism penetrates through the groove and the lug forming the bridge body and the bridge pier to fix the bridge body and the bridge pier together.
