Abstract
The utility model discloses a shock absorption and insulation device with a reset device. The shock absorption and insulation device comprises first spring bodies, second spring bodies and damping rubber. The first spring bodies are perpendicularly arranged on the two sides below a supporting base upper steel plate, steel bars are wrapped inside the damping rubber, the first spring bodies are integrally connected with the second spring bodies through the steel bars in the damping rubber, the first spring bodies and the second spring bodies are arranged perpendicularly, and the second spring bodies are connected with a supporting base lower steel plate. According to the shock absorption and insulation device, energy can be dissipated through the damping rubber when an earthquake just starts, and then the reset function is realized through the retractive force of the springs.
Description
Technical field
The utility model relates to the technical field of bridge horizontal shock-absorbing, relates in particular to a kind of seismic isolation device with resetting means.
Background technology
China, in circum-Pacific belt and the Asia-Europe area that affects with the two multiple districts of large violent earthquake, is a multiple state of earthquake.How antidetonation and damping are to carry out the problem that bridge design must be paid much attention to the anti-seismic performance that improves bridge.At present, the shock isolation system that subtracts of bridge is mainly that vibration absorption and isolation support is set in bridge construction, utilizes the shear strain of vibration absorption and isolation support self to make upper and lower part taphrogeny isolation, and absorbs seismic energy by the hysteretic energy of self, effectively absorb energy, alleviate earthquake effect.
Seismic isolation device can reduce the reaction of structure to earthquake motion greatly, has obvious safety and economic benefit.
Common frictional slip type vibration absorption and isolation support, involves great expense.And lamination vibration absorption and isolation support is generally without Self-resetting function.And vibration absorption and isolation support generally need be with regard to installation in position in the time that structure is set up.
Patents is bridge spring-rubber cushion block again, and it is porose in damping rubber, establishes spring in hole; It can not increase the power consumption effect of structure; Another Patents is that spring is located in rubber, and only a direction, can not provide restoring force from both direction, and practicality is not strong.
Summary of the invention
Because the above-mentioned deficiency of existing block technology the utility model proposes a kind of seismic isolation device with resetting means, when this seismic isolation device has just started earthquake, by damping rubber dissipation energy, realize Self-resetting function by the retraction force of spring thereafter.
For achieving the above object, the utility model provides a kind of seismic isolation device with resetting means, comprises the first spring body, the second spring body, damping rubber; Both sides, bearing upper steel plate below are vertically installed with respectively described the first spring body, in described damping rubber, be surrounded by steel bar, described the first spring body is connected with described the second spring body one by the described steel bar in described damping rubber, described the first spring body and the vertical setting mutually of described the second spring body, described the second spring body is connected with bearing lower steel plate.
Preferably, described steel bar two ends connect respectively the first spring body and the second spring body.
Preferably, described steel bar is chain shape steel chain or chain shape iron chains or round roller shape steel bar.
Preferably, described bearing upper steel plate, described bearing lower steel plate are respectively upper beam, Xia Dun, or upper prop, lower prop.
The beneficial effects of the utility model:
1, the steel within the damping rubber in the utility model or iron can connect the spring at two ends on the one hand, can increase by the distortion of steel on the other hand the power consumption effect of structure.
2, the utility model can be respectively structure at the spring of vertical and level the restoring force of vertical and level is provided.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
Brief description of the drawings

Detailed description of the invention
As Fig. 1, shown in Fig. 2, a kind of seismic isolation device with resetting means of the present embodiment, comprise the first spring body 1, the second spring body 2, damping rubber 3 and round roller shape steel bar 4, bearing upper steel plate 5 both sides, below are all vertically installed with the first spring body 1, the first spring body 1 is connected with the second spring body 2 by damping rubber 3, the first spring body 1 and the mutual vertical setting of the second spring body 2, between the second spring body 2, be connected with bearing lower steel plate 6, in described damping rubber 3, be surrounded by round roller shape steel bar 4, steel within damping rubber of the present utility model or iron can connect the spring at two ends on the one hand, can increase by the distortion of steel on the other hand the power consumption effect of structure.
Concrete, the damping rubber 3 of the present embodiment is circular arc, easy to use, reaches buffering effect.
In the present embodiment, described round roller shape steel bar 4 two ends connect respectively the first spring body 1 and the second spring body 2.Described round roller shape steel bar 4 is replaceable is chain shape steel chain or chain shape iron chains or round roller shape steel bar.Described bearing upper steel plate 5, bearing lower steel plate 6 can be respectively upper beam and lower pier or upper prop and lower prop.
This detailed description of the invention, by the combination unit of spring and damping rubber, both can have been passed through damping rubber dissipation energy, can realize by spring again the Self-resetting of bearing, and cost is also cheaper.Also can in structure use procedure, increase in addition this device.When this seismic isolation device has just started earthquake, by damping rubber dissipation energy, realize Self-resetting function by the retraction force of spring thereafter.This device can also be installed in the structure having come into operation in addition, and can be used as anti-fall girder apparatus.
An ingredient of this detailed description of the invention is Baogang or iron (both combine) in damping rubber, and steel or iron shape can be round roller shape or chain shape.Steel within damping rubber or iron can connect the spring at two ends on the one hand, can increase by the distortion of steel on the other hand the power consumption effect of structure; Spring is to be located at damping rubber two ends, and one section is that vertically one section is level, and spring vertical and level can be respectively structure provides the restoring force of vertical and level.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technician in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in by the determined protection domain of claims.
