Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
Application principle of the invention is explained in detail with reference to the accompanying drawing.
A kind of vertical vibration isolation seat structure for building of the invention as shown in Figs 1-4, including it is parallel positioned at upper and lower two sides
The support base 1 of setting is provided at least two vertical vibration isolation support units for pressing array arrangement in the intermediate space of support base 1
2, the vertical vibration isolation support unit 2 has been the core component of vertical bearing capacity effect.All embodiments as shown in Figure 4
In, the array manner of the arrangement can be annular array and be also possible to rectangular array.
It further include that marginal position is set for connecting the drag-line 3 of upper and lower seat 1 supported on both sides, in the horizontal direction to support
Seat 1 is limited.
Wherein, be the requirement for meeting structure vertical bearing capacity, the vertical rigidity of the vertical vibration isolation support unit 2 compared with
It is small, including be located at the vertically disposed steel pipe 202 in center and surround the connecting plate 201 disposed in parallel of steel pipe 202, sandwich clad steel
203 and vibration insulation 204, the connecting plate 201, sandwich clad steel 203 and vibration insulation 204 will be suppressed by vulcanization integral forming method
Together.
Be in contact since the connecting plate 201 is located at upper and lower two sides with support base 1, the sandwich clad steel 203 and every
Between vibration layer 204 or alternately it is arranged in the intermediate space of two side connecting plates 201.So the number ratio of the vibration insulation 204
The number of the sandwich clad steel 203 is one layer more, and the company is set to positioned at vibration isolation plate 204 described in top layer or lowest level
Between fishplate bar 201 and sandwich clad steel 203, positioned at the vibration isolation plate 204 of middle layer be set to adjacent two sides sandwich clad steel 203 it
Between.It include under normal conditions vibration insulation 204 described in layer 2-4, the thickness of the vibration insulation 204 is very thick, and thickness is basis
The demand of Vibration Absorbing System Design, which calculates, to be determined.
The vibration insulation 204 uses the lesser rubber layer 204_1 of vertical rigidity and constructs matrix.In the work of vertical load
Under, rubber layer 204_1, in order to limit this bulging, can joined along bulging is radially expanded in the inside of rubber layer 204_1
High-strength carbon fibre grid cloth 204_2.The high-strength carbon fibre grid cloth 204_2 includes the warp to intersect vertically as shown in Figure 3
Fiber 204_21 and parallel fiber 204_22, wherein the parallel fiber 204_22 is in the way of concentric circles to external diffusion.Its
The fiber carbon fiber very big using tensile strength, is embedded in thick rubber layer, fiber cloth surface brush coating stick and and rubber
Layer 204_1 integrated vulcanizing molding.When vertical load along support central role when on support, carbon cloth is powerful anti-using its
Tensile strength provides radial restraining force for rubber layer 204_1.Interlayer high-strength carbon fibre grid cloth 204_2 is to the vertical of support simultaneously
The influence of rigidity is very little, and the presence of interlayer high-strength carbon fibre grid cloth 204_2 strengthens the constraint for rubber radial direction, limit
The deformation of thick rubber layer 204_1 radially is made.
Set steel pipe 202 is excessive for preventing accidentalia effect flowering structure from generating in vertical vibration isolation support unit 2
Vertical Settlement.Vertical spacing steel pipe 202 is freely placed in 2 centre bore of vertical vibration isolation support unit, 202 aperture of steel pipe it is big
The small vertical bearing capacity with support matches.
In the present invention, the vertical vibration isolation support unit 2 be center of circle symmetric figure, such as cylindrical body, regular hexagonal prism,
Positive eight prism etc., preferably cylindrical body.The position in the center of circle, the connecting plate 201, interlayer is arranged in the steel pipe 202
Steel plate 203 or vibration insulation 204 are circular ring shape.
The horizontal rigidity of the support is smaller, has the function of horizontal seismic isolation, while needing to consider that horizontal direction limits.Using
Drag-line 3 is used as limiting device, and the extensional rigidity of drag-line 3 is larger, can play horizontal direction position-limiting action.Meanwhile support is in tension
Operating condition can play drawing-resistant function.3 both ends of drag-line are connected by pier anchor mode with the support base 1 of upper and lower two sides, and along
The outer ledge of support base 1 is evenly arranged.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
