Background
With the development of technology, the sizes of civil construction and bridge engineering are getting bigger and the heights of the civil construction and bridge engineering are increasing, and disasters caused by earthquakes are getting more serious. It is necessary to design shock absorption and isolation before construction. The purpose of shock insulation is to separate the structure or the component from the ground or the support motion and to cut off the propagation path of seismic energy; the shock absorption is to increase the damping, accelerate the consumption of earthquake energy under the reciprocating action caused by the earthquake, and reduce the earthquake reaction of the upper structure. In the prior art, the separation is generally realized by increasing the flexibility of a system and providing proper damping, the principle is that the self-vibration period of a building structure is properly prolonged by a shock isolation device, the damping characteristic of the structure is increased, the acceleration response of the structure is reduced, and meanwhile, the earthquake force can be uniformly distributed on each bearing member, so that the survival capacity of the building structure under the earthquake is improved.
According to different energy dissipation and shock absorption principles, the shock insulation types comprise laminated rubber support shock insulation, lead core rubber support shock insulation, ball (or roller) shock insulation, suspension foundation shock insulation, swinging support shock insulation, sliding support shock insulation and the like. The prior various shock-insulation supports have respective characteristics, but the best comprehensive performance is the laminated rubber shock-insulation support which is commonly used at present.

Most common supports are generally weak in vertical shock absorption capacity, small in displacement limit value under horizontal earthquake and easy to damage under the action of large earthquake. The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a method for manufacturing a display device.

The bending rigidity of the joints of the upper bending arc-shaped beam 6, the lower bending arc-shaped beam 7 and the connecting block is high, so that collision with adjacent beams during vibration is avoided; the bending rigidity of the free extension section in each direction is small, the deformation capability is strong, and large deformation can be generated to absorb seismic energy.
The beam bodies of the upper bending arc beam 6 and the lower bending arc beam 7 are both stuck with a constraint steel plate layer 15 through a damping bonding layer 14, so that a large amount of earthquake energy can be absorbed when the bending arc beams generate large deformation, and the structure can be quickly damped to reduce vibration.
The plane of the upper connecting plate 2 and the plane of the lower connecting plate 3 are consistent with the local shape of the connected main body structure, the upper connecting block 4 and the lower connecting block 5 are circular or regular polygon, and the distance between the upper connecting plate 2 and the upper connecting block 4 and the distance between the lower connecting plate 3 and the lower connecting block 5 at least keep the distance capable of supporting the jack, so that the jack can be maintained and replaced conveniently in the future.

When the beam-type elastic shock absorption and isolation support is not deformed, the centroids of the end sections of the upper bent arc-shaped beam 6 and the lower bent arc-shaped beam 7 which are connected up and down, the centroids of beam end connecting pieces 9 for connecting the upper bent arc-shaped beam and the lower bent arc-shaped beam and the centroids of beam-type elastic shock absorption and isolation support are on the same horizontal projection line, so that torsion between the upper part and the lower part of the beam-type elastic shock absorption and isolation support is prevented.
And internal stiffening ribs 16 are arranged on the upper connecting block 4 and the lower connecting block 5.
The working principle of the invention is as follows:
the upper main body structure and the lower main body structure are connected through the connecting plate, the connecting block, the rubber pad and the sliding contact steel panel to realize free sliding contact between the upper sliding contact steel panel and the lower sliding contact steel panel, and only vertical load is transmitted. The contact surface does not bear any horizontal force, and the contact surface can be restored to the original position in the horizontal direction by a small horizontal restoring force.
The horizontal seismic force is borne by the bending arc-shaped beams which are axially symmetrical and uniformly distributed on the peripheries of the upper connecting block and the lower connecting block. When the upper and lower structures are dislocated due to earthquake, the upper and lower connecting blocks are also dislocated relatively along with the main structure, and at the moment, the arc-shaped beams 6 are bent on two sides connected with the upper connecting block 4, so that the bending radian of one side is increased, the bending radian of the other side is reduced, and meanwhile, the bending radian of one side is reduced and the bending radian of the other side is increased by the vertically corresponding lower bending arc-shaped beam 7. The deformed curved arc-shaped beam generates horizontal forces at both ends like the counterforce of an arched support, and the resultant force of the forces is connected with the centroid of the steel panel through the upper part and the lower part in sliding contact, namely, the horizontal restoring force is generated. The elastic deformation of the bent arc-shaped beam can be limited by designing the section moment of inertia and the radian of the bent arc-shaped beam, so that the maximum displacement between the upper sliding contact steel panel and the lower sliding contact steel panel is controlled, and the horizontal seismic reaction of the upper structure is limited; the self deformation of the bent arc-shaped beam and the restrained steel plate layer 15 around the beam can better absorb earthquake energy, quickly attenuate structural vibration, reduce structural damage and reduce the uncomfortable feeling of the structure during use; after the earthquake is stopped, the restoring force can be provided, so that the upper structure is restored to the original position.
During vertical vibration, the beam type elastic seismic isolation support can be disconnected at the upper and lower sliding contact steel panels, moves up and down relatively, can provide vertical counter-force at the moment when the arc-shaped beam is bent, and restrains the maximum vertical displacement between the upper main body structure and the lower main body structure. The maximum displacement can be obtained by calculating the deformation of the parallel-superposed upper and lower bending arc beams according to the method of calculating the vertical deflection deformation of the normal steel beam. The self deformation of the bent arc-shaped beam and the restraint damping coating on the periphery of the beam can better absorb seismic energy and reduce vertical vibration amplitude. When the main structure is influenced by gravity to rapidly return to the original position, the inertia can generate large impact force, and the main structure can be buffered by the upper rubber shock isolation cushion and the lower rubber shock isolation cushion at the moment, so that vertical seismic energy is absorbed, the vertical seismic impact force is reduced, and vertical seismic feeling is slowed down. The axisymmetrical uniformly arranged upper and lower curved arc beams with opposite bending directions can also provide restoring force for resisting torsion.
The upper connecting plate 2 and the lower connecting plate 3, the upper connecting block 4 and the lower connecting block 5, the upper curved arc beam 6 and the lower curved arc beam 7, the upper rubber pad 10 and the lower rubber pad 11, the upper sliding contact steel panel 12 and the lower sliding contact steel panel 13 have the same structure.
The invention has the beneficial effects that: the beam type elastic shock absorption and isolation support has the advantages that the vertical shock absorption capacity is realized, the maximum vertical displacement can be limited, the upper part main structure and the lower part main structure can be allowed to freely move in the horizontal earthquake, and the large horizontal displacement can be generated, so that the shock absorption and isolation effects are realized, the structure is simple, the manufacturing cost is low, the maintenance is easy, and the structural earthquake reaction can be effectively reduced.
