The shock isolating pedestal makes shock insulation by the way that the multilayer rubber layer and multilayer steel plates layer that are alternately arranged are arranged between upper sealing plate and lower sealing plate Support is able to bear compression and the stretching action of horizontal direction and vertical direction earthquake generation.
Summary of the invention
In view of the above technical problems, the present invention provides it is a kind of with resistance to plucking, limit, damping function three-dimensional isolation branch Seat is in to solve shock isolating pedestal in the prior art and draws withdrawal resistance and restoring force under scissor state can be weak, and can limit every Shake support is more than the technical issues of horizontal displacement destroys.
A kind of technical solution of three-dimensional shock isolation support with resistance to plucking, limit, damping function of the invention is:
Three-dimensional shock isolation support with resistance to plucking, limit, damping function includes circumferential buckling-restrained plate, upper sealing plate and lower envelope Plate, the buckling-restrained plate of circumferential direction and upper and lower sealing plate surround constraint chamber, and the constraint is intracavitary to be arranged rubber bodies of putting more energy into, rubber of putting more energy into Colloid is that multilayer rubber layer and multilayer steel plates layer are alternately superimposed on along the vertical direction, edge and the constraint chamber of the rubber layer Inner wall fits closely, upper sealing plate, the upper end of restraining plate, lower sealing plate, restraining plate lower end set connection bolt hole.
The beneficial effect is that: the circumferential direction in the three-dimensional shock isolation support with resistance to plucking, limit, damping function of the invention is bent Bent restraining plate and upper and lower sealing plate surround constraint chamber and enhance the vertical bearing capacity of shock isolating pedestal, rubber layer and constraint cavity wall It fits closely, rubber layer is constrained.When earthquake of the shock isolating pedestal by horizontal direction, rubber layer and steel plate layer can disappear The kinergety of shock isolating pedestal is consumed, circumferential buckling-restrained plate can provide the restoring force in three directions to shock isolating pedestal.Compared to Shock isolating pedestal in the prior art, it will be support that three-dimensional shock isolation support of the invention, which is in and draws circumferential buckling-restrained plate under scissor state, Withdrawal resistance and restoring force are provided, and limits the horizontal and vertical carry of support and moves destruction.
Further, the buckling-restrained plate of the circumferential direction is that the external radius in middle part is big, the small drum organization of the external radius in both ends. Circumferential buckling-restrained plate is drum organization, increases horizontal direction deformability, and be capable of providing damping force, and limits support level It moves and destroys with vertical carry.
Further, rubber bodies of putting more energy into are completely wrapped in circumferential buckling-restrained plate and the formation constraint of upper and lower sealing plate is intracavitary.
Further, upper sealing plate, restraining plate upper end, lower sealing plate, restraining plate lower end set bolt hole, pass through bolt and external knot Structure is connected.
Further, rubber bodies of putting more energy into are using vulcanization filling constraint chamber and form one.
Further, two middle side parts up and down of the buckling-restrained plate of the circumferential direction of cydariform all have circular open, and upper and lower sealing plate is With the plectane of circular open cooperation.

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below Example is not intended to limit the scope of the invention for illustrating the present invention.
It is of the invention with resistance to plucking, limit, damping function three-dimensional shock isolation support specific embodiment one, as shown in Figure 1, Figure 2 It is shown, including circumferential buckling-restrained plate 1, upper sealing plate 2 and lower sealing plate 3, circumferential buckling-restrained plate 1, upper sealing plate 2 and lower sealing plate 3 It is metal plate.Circumferential buckling-restrained plate 1, upper sealing plate 2 and lower sealing plate 3 surround constraint chamber, and circumferential buckling-restrained plate 1 is outside middle part Connect that radius is big, the small drum organization of the external radius in both ends, likewise, constraint chamber is that cydariform constrains chamber.
It constrains and intracavitary has been alternately superimposed on multilayer rubber layer 4 and multilayer steel plates layer 5, and the edge of rubber layer 4 along the vertical direction It is fitted closely with the inner wall of circumferential buckling-restrained plate.In the present embodiment, the radius close to the steel plate layer 5 in middle position is maximum, and two The radius of the steel plate layer 5 of side is gradually reduced, to guarantee the both ends of each layer steel plate layer 5 and being equidistant for constraint cavity wall.
The upper and lower ends of the buckling-restrained plate 1 of the circumferential direction of cydariform bend up consistent with support end, have the horizontal edge that extends internally, The medial surface on horizontal edge surrounds circular open, the central axis of the central axis of circular open and the buckling-restrained plate 1 of the circumferential direction of cydariform Line coincides.The bore of the opening of the upper and lower ends of the buckling-restrained plate 1 of the circumferential direction of cydariform is equal, and upper sealing plate 2 is and upper end opening The circular slab of split, lower sealing plate 3 are the circular slab with lower ending opening split.
With resistance to plucking, limit, damping function three-dimensional shock isolation support upper sealing plate 2 and lower sealing plate 3 on offer sealing plate respectively Screw hole 6, six screw holes on upper sealing plate 2 and lower sealing plate 3 are circumferentially uniformly distributed, by cooperating with bolt, for by upper sealing plate 2 and lower envelope Plate 3 is fixedly connected with external structure respectively.
7 circumferential buckling-restrained plate spiral shells are respectively provided on the upper level-end and lower level-end of the buckling-restrained plate 1 of the circumferential direction of cydariform Hole, by cooperating with bolt, to be fixedly connected with external structure.
In the present embodiment, rubber layer 4 is rubber or other elastic materials, and rubber layer 4 is filled in about by sulfuration process Beam is intracavitary, so that rubber layer 4 is fitted closely with constraint cavity wall.
Of the invention has the three-dimensional shock isolation support of resistance to plucking, limit, damping function in use, when shock isolating pedestal is by level When the earthquake in direction, rubber layer 4 and steel plate layer 5 can consume the kinergety of shock isolating pedestal, and circumferential buckling-restrained plate 1 can be given Shock isolating pedestal provides the restoring force in three directions.Compared with common shock isolating pedestal in the prior art, it is of the invention have resistance to plucking, Limit, damping function three-dimensional shock isolation support in the buckling-restrained plate 1 of circumferential direction of cydariform strengthen shock isolating pedestal and vertically carry energy Power can provide resistance to plucking function and restoring force to shock isolating pedestal, and limit the horizontal and vertical carry of support and move destruction, while week The damping force of horizontal direction can also be provided by bending up to buckling-restrained plate 1, and external structure deforms when reducing earthquake or vibration.Also, Three-dimensional shock isolation support low cost of the invention, easy to process, installation is simple.
