Description
Technical field
The present invention relates to a kind of bearing, be specifically related to a kind of removable laminated rubber bearing that has.
Background technology
In recent decades, subtract vibration isolating suspension and subtract the important measures of vibration isolation as bridge, obtained increasing attention, and obtained great development.Various support style layers go out not ask, and wherein laminated rubber bases has obtained using widely.Laminated rubber bases is when meeting with earthquake or great vibratility and impact, and rubber layer is consumed energy in deformation process, and damping is provided, and resets after shake.But in view of the substantive characteristics of elastomeric material, neoprene bearing is in the field work state for a long time in addition, and poor durability, maintenance difficulty often need to change.When changing, need the jacking back timber, the jacking amount is excessive to have certain influence to building intensity, and marquis's destructive power is excessive sometimes, causes the distortion of bearing fastening bolt, makes that the bearing replacement difficulty of construction is big.In addition, under big shake effect, only depend on the effect of rubber deformation power consumption not obvious, topple because being out of shape the excessive top beam body unstability that makes easily, when serious Luo Liang may take place, the major accident of the frame that falls.Thereby existing support style demanded urgently improving.
Summary of the invention
In order to remedy the defective of prior art, patent of the present invention provides a kind of removable laminated rubber bearing that has, can have good energy dissipation capacity under the shake effect doughtily, after destroying, it also is convenient to change, the jacking amount is little in the replacing process simultaneously, engineering time is short, can effectively reduce Luo Liang, security incident such as the frame that falls takes place.It has tangible economy and practical value.
In order to realize above-mentioned technical purpose, the technical scheme of patent of the present invention is, the present invention is a kind of laminated rubber bearing, comprise connect steel plate with under be connected steel plate, last connection steel plate with under be connected and be provided with the half rounds sleeve between the steel plate, two half rounds sleeves are provided with neoprene bearing to being fastened as the full circle steel bushing in the full circle steel bushing, on connect steel plate with under be connected and also be provided with dismounting jack and load sharing steel cylinder between the steel plate.
The present invention is that also the inwall of full circle steel bushing is provided with the marmem ball.
The present invention is that also the marmem ball is in length and breadth on the inwall that is set in qually spaced in the full circle steel bushing.
The present invention also is, also is provided with the reinforcement steel plate in the neoprene bearing.
The present invention is that also the position correspondence of two half rounds sleeve make-ups is provided with locating slot.
The present invention is that also locating slot is near last connection steel plate and/or connection steel plate setting down.
The present invention is that also arranging in the locating slot fixedly has limiting plate.
The present invention is that also limiting plate is connected on the upper surface and/or soffit of neoprene bearing.
The present invention is that also limiting plate is provided with and connects connector up and down.
The present invention also is, on to connect steel plate and/or connect steel plate down be rectangular slab.
The present invention also is, on four angle parts that connect steel plate and/or connect steel plate down be provided with load sharing steel cylinder.
The present invention is that also the axis of load sharing steel cylinder is provided with stay bolt.
The present invention also is, is provided with the dismounting jack between two load sharing steel cylinders.
The present invention also is, is provided with the dismounting jack between one group of symmetrically arranged two load sharing steel cylinder.
The present invention also is, the upper and lower of dismounting jack connect respectively steel plate with under be connected steel plate.
Patent beneficial effect of the present invention is:
A, have good energy dissipation capacity under the shake effect doughtily, also be convenient to change after it destroys, the jacking amount is little in the replacing process simultaneously, and the engineering time is short, and security incidents such as load sharing steel cylinder can effectively reduce Luo Liang, the frame that falls take place.Solved the part difficult problem of existing neoprene bearing, it has tangible economy and practical value.
B, arranged load sharing steel cylinder respectively at neoprene bearing four jiaos, it can share the performance that the bearing upper load does not influence bearing again at ordinary times, and can prevent that neoprene bearing distortion is excessive and cause the superstructure unstability and topple, when neoprene bearing under shake effect or outside thump doughtily destroys and when needing to change, the limiting plate of both sides then only need come loose, utilize prior specific placement in a small amount of jacking superstructure of simple and easy dismounting jack of bearing both sides then, can take out ruinate neoprene bearing changes, the marmem ball that is arranged in addition in the half rounds sleeve can realized energy by collision under the shake effect doughtily, the energy-dissipating property under the macroseism of raising bearing.Patent of the present invention have change convenient, to change the jacking amount little, the anti-unstability outstanding feature of toppling, consume energy.
Below in conjunction with accompanying drawing patent of the present invention is described further.
