Description
Technical field
The present invention relates to a kind of elastic reset resistance to plucking earthquake isolating equipments, belong to sliding and shock isolation technical field.
Background technique
The sixties in last century people have begun to then just start to non-anchored storage tank the earthquake research of anchoring storage tank
It is studied, with the appearance of lift-off problem in non-anchored storage tank, last century the seventies have started about storage tank lift-off mechanism
Research.Although being in progress, since non-anchored storage tank is more complicated than the seismic response for anchoring storage tank very much, so about non-anchored
The research achievement of storage tank is rarely applied in Practical Project.But non-anchored storage tank destroys more under geological process than anchoring storage tank
Add seriously, so there is an urgent need to study the isolation measure for being directed to non-anchored tank structure feature.
Sliding base-isolation technology is using one of seismic isolation technology earlier, although principle is simple, isolating affection is obvious,
Since the relative displacement of the generation between superstructure and basis is difficult to reset, so seldom using this seismic isolation technology merely.
It is well known that rubber earthquake isolation support has preferable reset capability, so being widely used in various configurations.Early stage is common rubber
Glue shock isolating pedestal, then development is lead rubber laminated bearing, and laminated rubber damping bearing had been developed as most in recent years
Extensively, most mature isolation measure, but its construction is complicated, and cost is higher.If laminated rubber damping bearing is applied to merely non-
It anchors between storage tank bottom plate and basis, since the anti-pulling capacity of laminated rubber bases is limited, under excessive lift-off effect, folds
Layer rubber support is likely to be destroyed.Laminated rubber bases can make non-anchored storage tank homing after geological process, but
The problem of its limited anti-pulling capacity can't resolve non-anchored storage tank lift-off height.Then the present apparatus is in laminated rubber bases
On the basis of improve, increase anti-pulling device.The novel place of the present apparatus is this device with elastic reset shock insulation function
While energy, moreover it is possible to play resistance to plucking function before laminated rubber bases destruction, can effectively solve non-anchor fixing structure because of lift-off height
Spend it is big caused by topple risk problem, and simple structure, it is cheap easy, therefore study this non-anchored storage tank elastic reset
Isolating affection of the resistance to plucking earthquake isolating equipment in storage tank is particularly important.
For the actual needs of current non-anchored storage pot shock insulation technology, a kind of non-anchored storage tank elastic reset resistance to plucking has been invented
Earthquake isolating equipment.It include laminated rubber bases and anti-pulling device in the device, laminated rubber bases are bearing structure upper self weight
Simultaneously, additionally it is possible to the natural vibration period that certain horizontal rigidity carrys out extending structure is provided, to reduce geological process；Due to storage tank and
Non-anchor between basis to be solidly connected, after tank bottom comparative basis lift-off certain altitude, anti-pulling device then effectively can avoid tank bottom from generating
Further lift-off；And superstructure is returned to original position using the elastic reset function of laminated rubber bases after geological process.
Present apparatus simple structure, cheap, feasibility is strong, and isolating affection is obvious, has weight for the shock insulation research of non-anchored storage tank
Want meaning.
Summary of the invention
Pure rubber shock isolating pedestal has preferable recovery capacity, but cost is higher, and rubber support bearing capacity is limited, non-
Storage tank etc. is anchored with lift-off excessive in the structure of lift-off problem there is a possibility that rubber support destroys.Laminated rubber bases and
Anti-pulling device is grouped together, and by reasonable Arrangement, forms a kind of new non-anchored storage tank elastic reset anti-pulling device.It will be this
Earthquake isolating equipment is welded on non-anchored storage tank bottom plate in the following, making non-anchored storage tank under geological process, can not only effectively avoid excessive
Lift-off height, and can also after shake homing, can not only optimize isolating affection, moreover it is possible to appropriate to reduce storage pot shock insulation structure
The cost of aspect.
Non-anchored storage tank elastic reset resistance to plucking earthquake isolating equipment of the present invention, including upper cover plate, laminated rubber, lower seat
The composition such as plate, pre-embedded steel slab and embedded bar.The earthquake isolating equipment is mainly characterized by: the special tectonic of upper cover plate is capable of providing
Resistance to plucking function efficiently solves the problems, such as that non-anchored storage tank lift-off height is excessive；Lamination rubber is set between upper cover plate and lower seat board
Glue support, while reducing geological process, moreover it is possible to make superstructure be returned to origin-location using the elastic reset function of rubber；
And this device maximum lift-off height allowed has to the elastic polarity vertical deformation less than laminated rubber bases, guarantees
Laminated rubber bases are in elastic stage always, so that the uplift effect performance of upper cover plate is pulled off in laminated rubber bases
Before, it is ensured that laminated rubber bases can play elastic reset function after geological process so that superstructure be returned to it is original
Position.
The invention mainly relates to following several respects contents:
Elastic reset resistance to plucking earthquake isolating equipment, the device by upper cover plate 1, connection anchor bolt 2, upper sealing plate 3, lead for retractable pencil 4, sheet metal 5,
The composition such as sheet rubber 6, rubber protective layer 7, lower sealing plate 8, lower seat board 9, weld seam 10, pre-embedded steel slab 11, embedded bar 12.
Lower seat board 9 is fixed by welding on pre-embedded steel slab 11, and the company of lower seat board 9 and pre-embedded steel slab 11 is arranged in weld seam 10
Meet place；Embedded bar 12 is preset in pre-embedded steel slab 11；Upper cover plate 1 is U-shaped structure, the bosom and upper sealing plate 3 of upper cover plate 1
It is connected, upper sealing plate 3 is connect by connecting anchor bolt 2 with upper cover plate 1；The top of lower seat board 9 passes through connection anchor bolt 2 and lower 8 phase of sealing plate
Even；Rubber protective layer 7 is arranged in 6 interfolded of several layers sheet metal 5 and sheet rubber, side surface, by upper sealing plate 3, sheet rubber 6, thin
There are the circles of perforation upper sealing plate 3 and lower sealing plate 8 for the centre of the cylinder support of steel plate 5, rubber protective layer 7 and lower sealing plate 8 composition
Lead for retractable pencil 4 is filled in hole in round hole；Between upper sealing plate 3 and upper cover plate 1, pass through connection anchor bolt 2 between lower sealing plate 8 and lower seat board 9
Connection；Rubber protective layer 7 is arranged between upper sealing plate 3 and lower sealing plate 8.
The U-shaped structure of upper cover plate 1, which avoids superstructure, excessive lift-off height.
The cylinder support being made of upper sealing plate 3, sheet rubber 6, sheet metal 5, rubber protective layer 7, lead for retractable pencil 4 and lower sealing plate 8
