Description
Technical field
The utility model relates to structure quake control technology field, in particular to a kind of vertical earthquake isolating bearing.
Background technology
Shock isolating pedestal is the shockproof isolating device be located between building or equipment etc. and basis; it mainly reduces the fundamental frequency of structure quake; extend the vibrations cycle; thus avoid the Domain energy channel of earthquake motion; superstructure and earth shock are isolated; reduce superstructure reaction, reach the object protecting agent structure and inner facility thereof not to be damaged.
Because vibrations vertical in earthquake can not be ignored the impact of works, easily there is resonance and destroy in especially tall and slender structure or longspan structure etc. in earthquake.The laminated rubber damping bearing that existing shock isolating pedestal is mainly superimposed to form by rubber and steel sheet, be mainly horizontal seismic isolation, not good enough to the isolating affection of vertical vibrations, very unfavorable to structural safety, and when standing geological process, be difficult to the torsional shear moment overcoming generation.The employing multidimensional shock insulation support also had, but its structure and complex manufacturing technology, cost is higher, is unfavorable for promotion and application.
Utility model content
The purpose of this utility model is to provide that a kind of vertical vibration isolation is effective, structure simple, can the vertical earthquake isolating bearing of anti-torsion, to solve the problem.
For realizing the utility model object, the technical scheme of employing is: a kind of vertical earthquake isolating bearing, comprises the upper bearing plate offered reeded lower bearing support He be positioned at described groove; The perimeter rows of upper bearing plate is furnished with fin, the cell wall of groove offers the rib groove matched with fin; The cell wall of rib groove and groove is provided with damping layer, and bottom land is provided with Seismic Isolation of Isolation Layer.
Further, described upper bearing plate is cylindric plate, the fin on it at least two, and arranges at the periphery Central Symmetry of upper bearing plate.
Further, the end face of described upper bearing plate is higher than the end face of lower bearing support.
Further, described damping layer is damping rubber or pitch.
Further, described Seismic Isolation of Isolation Layer is mutually superposed by rubber layer and steel plate layer and is formed by connecting.
Further, described lower bearing support is fixedly connected with bottom bearing structure.
Further, described groove is open the through slot to lower bearing support bottom surface.
The beneficial effects of the utility model:
1, the energy consuming earthquake is absorbed by the Seismic Isolation of Isolation Layer between lower bearing support and upper bearing plate, there is larger vertical bearing capacity, also there is enough vertical deformation abilities and reset capability simultaneously, under equipment or the normal behavior in service of building structure, the all wt of the support superstructure of safety and maneuvering load, have suitable vertical rigidity, separate vertical vibrations, vertical earthquake isolating is effective;
2, the damping layer between upper bearing plate and lower bearing support groove cell wall, play the effect of buffering, and the vibrational power flow of fin, rib groove and the damping layer between the two bears the torsional shear in vibrations, control torsional deflection, improve the stability of shock isolating pedestal, overcome the problem of the anti-twisting property difference of existing shock isolating pedestal, resistance to capsizing is strong;
3, according to different practical structures situations, the fin of respective numbers and the shape of arranging at upper bearing plate periphery, its monnolithic case is similar to gear, embedded in the groove and rib groove matched by it, meet the circumferential shearing force of different size, reach anti-twisting property in various degree, easy to process, can be used for equipment or build isostructural vibration isolation, and structure is simple, cost is low, is beneficial to wide popularization and application.
Accompanying drawing explanation
Fig. 1 is the axonometric drawing of the vertical earthquake isolating bearing that the utility model provides;
Fig. 2 is the decomposing schematic representation of the vertical earthquake isolating bearing that the utility model provides;
Fig. 3 is the sectional view of the vertical earthquake isolating bearing that provides of the utility model when installing.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 to Fig. 3 shows the vertical earthquake isolating bearing that the utility model provides, and comprises the upper bearing plate 2 offered reeded lower bearing support 1 and be positioned at groove; The perimeter rows of upper bearing plate 2 is furnished with fin 21, the cell wall of groove offers the rib groove 11 matched with fin 21; The cell wall of rib groove 11 and groove is provided with damping layer 3, bottom land is provided with Seismic Isolation of Isolation Layer 4.
Such upper bearing plate 2 is positioned on Seismic Isolation of Isolation Layer 4, upper bearing plate 2 is cylindric plate, fin on it 21 at least two, and arrange at the periphery Central Symmetry of upper bearing plate 2, better can bear shearing force uniformly by its entirety, make the damping layer 3 in each rib groove 11 that shear strain occur, thus evenly absorb twisting resistance fully.The cross section of fin 21 can rectangular, swallow-tail form, arc or other polygons.
The end face of upper bearing plate 2 is higher than the end face of lower bearing support 1, make its convenient being connected with superstructure, especially when superstructure is larger, be equal to or greater than situation during upper bearing plate 2, upper bearing plate 2 exceeds lower bearing support 1, superstructure can be avoided to touch lower bearing support 1 and make lower bearing support 1 directly carry the weight of superstructure, ensure that the structures such as all top-outs can be absorbed by the Seismic Isolation of Isolation Layer between upper bearing plate 2 and lower bearing support 1 and consume vibration energy, applicability is stronger.
Damping layer 3 is damping rubber or pitch, and other also can be adopted to have the material of damping capacity.Seismic Isolation of Isolation Layer 4 is mutually superposed by rubber layer and steel plate layer and is formed by connecting, and the thickness of rubber layer and steel plate layer can be determined according to specific needs, also can adopt damping rubber layer or the shock insulation material structures such as multiple spring or lead damper of arranging.
The groove of lower bearing support 1 can be the non-penetrating groove of the recessed certain depth from its surface, also can be the through slot opened to lower bearing support 1 bottom surface, specifically according to circumstances establishes.
When this shock isolating pedestal is installed, lower bearing support 1 is fixedly connected with bottom bearing structure, specifically can directly by bolt, lower bearing support 1 be fixed on the bearing structure of bottom, also by by lower bearing support 1 connection base plate 5, be fixed on the bearing structure of bottom by mounting base 5, upper bearing plate 2 needs the anatomical connectivity of shock insulation to fix by installing top board 6 with top, thus plays vibration isolation effect to the structure on top.Bottom bearing structure can be the structure that in building, bearing support effect is played on the support post of floor gap, bridge pier or ground etc.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
