Structure or arcuate structure.The steel bomb body antidetonation of the present embodiment, vibration damping bridle iron use the elastomer of A type structure or arcuate structure
Element 12, when bridge, building are because the factors such as temperature, wind load, seismic (seismal occur horizontal displacement and when deformation, steel bomb body
7 side tension of elastic device, side are pressurized, and restoring force is stable, uniform.The elastic volume elements of this A type structure or arcuate structure
Part 12, relatively conventional unilateral arc plate shape plate spring structure, is advantageous in that 7 side tension of steel bomb body elasticity device, and side is pressurized, and makees
Firmly in the same direction, relatively conventional unilateral arc plate shape plate spring structure, under elastic stiffness unanimous circumstances, material can save half, simultaneously
Avoid abrasion, the deformation, stuck problem in conventional unilateral arc plate shape leaf spring use process between arc tip and limit plate 9.
Single elastomer element 12 can be set in the steel bomb body elasticity device 7 of the present embodiment, and multiple elasticity also can be set
Volume elements part 12, size, horizontal rigidity, the horizontal displacement of horizontal restoring force etc. with specific reference to demand are designed, change quantity,
Structure size, arrangement form, to reach design requirement.Preferably, elastomer element 12 at least there are two, be located at lower support plate 6
(bow-shaped structural of two elastomer elements 12 or the opening of A character form structure are oppositely arranged between the elastomer element 12 of the same side
It is either disposed opposite to each other (bow-shaped structural of two elastomer elements 12 or the opening of A character form structure mutually deviate from) relatively), certainly
Can make the opening of each two elastomer element 12 of 6 the same side of lower support plate towards identical, between each elastomer element 12 away from
From can be identical.Further, the elastomer element 12 of two sides opposite in lower support plate 6 is arranged in a one-to-one correspondence, regardless of steel
Frame elastic device 7 is arranged how many a elastomer elements 12, the position of the elastomer element 12 of opposite two sides in lower support plate 6
And number corresponds, to guarantee that restoring force is stable, uniform.
Further, elastomer element 12 includes the first steel plate reed and the second steel plate reed, the first steel plate reed

The other end of piece is fixedly connected with the other end of the second steel plate reed by anchor 11, as shown in figure 4, can specifically pass through bolt
The mode for connecing or riveting is carried out from anchor.Steel bomb body elasticity device 7 provided by the invention can provide stable horizontal restoring force, and
Height difference will not be generated in operational process, superstructure is promoted to return to initial position, drive a vehicle bridge without influence.
Further, as shown in figure 3, one end of the first steel plate reed and one end of the second steel plate reed are equipped with for even
The mounting hole that fitting 8 passes through, it is preferable that the mounting hole cooperated with connector 8 is waist round hole, and steel bomb body elasticity device may be implemented
7 opposite sliding and steel bomb body elasticity the device 7 opposite slidings with lower support plate 6 with limit plate 9, meet turning for horizontal direction
Angle provides stable restoring force.
Further, it is arranged with washer on part of the connector 8 between the first steel plate reed and limit plate 9, even
Fitting 8 is arranged with washer on the part between the second steel plate reed and lower support plate 6.The present embodiment is in the first steel plate reed
Connect with limit plate 9, when the second steel plate reed is connect with lower support plate 6, can between the first steel plate reed and limit plate 9 and
It adds that coefficient of friction is small, material of excellent wear-resisting property is as washer between second steel plate reed and lower support plate 6, can also increase
Lubricating arrangement, or smear lubricant and lubricating grease, to reduce the vertical direction of limit plate 9,6 direction of displacement of lower support plate respectively
Frictional force effect, when support realizes bidirectional displacement, steel bomb body elasticity device 7 will not be damaged because of frictional force, be reduced simultaneously
Support itself internal force, restoring force are more stable.
Further, the bottom surface of upper bracket plate 1 is equipped with stainless steel plate 2, and upper stainless steel plate 2 is welded with upper bracket plate 1
An entirety is formed, is provided with upper wearing plate 3 between upper stainless steel plate 2 and intermediate liner plate 4, as shown in Figure 1, intermediate liner plate 4
Bottom surface be upper concave spherical surface, the top surface of intermediate liner plate 4 be the upper convex spherical to match with upper concave spherical surface, upper concave spherical surface and convex ball
Upper wearing plate 3 is set between face.Further, lower wearing plate 5 is provided between intermediate liner plate 4 and lower support plate 6, such as Fig. 1 institute
Show, the top of lower support plate 6 is lower concave spherical surface, and the bottom surface of intermediate liner plate 4 is lower convex spherical, between lower concave spherical surface and lower convex spherical
Lower wearing plate 5 is set.
When being installed on the steel bomb body antidetonation of the present embodiment, vibration damping bridle iron in bridge or building, if bridge, building
Because the factors such as temperature, wind load, seismic (seismal occur horizontal displacement and when deformation, support upper bracket plate 1, intermediate liner plate 4, under
Relative displacement is generated between support plate 6, final support upper bracket plate 1 generates horizontal displacement and deviates initial position；It can horizontal extension
The side of steel bomb body elasticity device 7 connect with lower support plate 6, the other side is connect with limit plate 9, when limit plate 9 and undersetting
When the unilateral gap of plate 6 increases, corresponds to the horizontal restoring force of steel bomb body elasticity device 7 and stablize increase, when limit plate 9 and lower support plate
When 6 unilateral gaps reduce, it is even reversed to correspond to the stable reduction of the horizontal restoring force of steel bomb body elasticity device 7；Due to this support
7 surrounding of steel bomb body elasticity device is arranged symmetrically, and in vertical bridge to 2 directions in 2 directions and direction across bridge, or builds main glide direction
2 directions in 2 directions and secondary glide direction, horizontal direction amount to four direction and are provided with elastomer device, when support occurs
When displacement, side tension, side is pressurized, and can realize damping, buffering in horizontal any glide direction, and export maintenance level and return
Multiple power makes upper bracket plate 1 and lower support plate 6 be displaced return, plays horizontal direction damping (vibration) function and pooling feature, protects bridge
Beam and building superstructure safety improve elastomer and utilize effect simultaneously because two sides steel bomb body elasticity device 7 functions both on
Rate.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, In
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
Within protection scope.
