Abstract
The invention belongs to the field of buildings and relates to a laminated rubber support seat. The laminated rubber support seat comprises an upper connecting member (1) and a lower connecting plate (2), wherein the upper connecting member (1) is positioned above the lower connecting plate (2); a stressed rubber gasket layer (4) is arranged in the upper connecting member (1); a shear press rubber gasket layer (5) is arranged between the upper connecting member (1) and the lower connecting plate (2); and the stressed rubber gasket layer (4) is fixedly connected with the shear press rubber gasket layer (5) through pulling and tying a steel stranded wire (7). When earthquake occurs, the shear press rubber gasket layer can generate vertical and horizontal deformation to bear an upper structure load and a vertical earthquake pressure; and the stressed rubber gasket layer bears the vertical earthquake tensile force generated at the support seat, so that the seismic isolation effect of a seismic isolation support seat can be achieved and the rubber support seat is prevented from being damaged when the support seat generates the tensile force.
Description
Technical field
The invention belongs to building structure earthquake isolation technical field, relate to a kind of laminated rubber bases.
Technical background
So-called base isolation structure is exactly between works and basis; Earthquake isolating equipment is set; In order to extending structure natural vibration period, increase structural damping, stop the transmission of seismic energy to superstructure, in the hope of reducing the earthquake effect of structure, thus the structural system that forms.Lead rubber bearing is exactly a kind of widely used earthquake isolating equipment; During use it is arranged between structure and basis; So both can bear the vertical load of superstructure; Because its lateral flexibility can intercept upwards transmitting of seismic energy again, can also consume and absorb seismic energy simultaneously, the safety of protection superstructure.
The vertical compression bearing of isolation structure principal security lead rubber bearing and laterally shear-carrying capacity at present, this is because this kind bearing has good pressurized performance and shear behavior.But when big or laminated rubber bases horizontal shear distortion is big when big, the vertical geological process of works depth-width ratio; All can produce tensile stress at bearing total cross-section or partial cross section; And the General Purpose Rubber shock isolating pedestal drawn bearing capacity very poor; Under less tensile stress, just destruction maybe be produced, thereby the destruction of whole shock insulation layer maybe be caused.
Summary of the invention
The objective of the invention is to for the defective that overcomes prior art provides a kind of lead rubber bearing that bears pulling force, the destruction of bearing under tension when this bearing can be avoided earthquake can be played the purpose of shock insulation again.
To achieve these goals, the technical scheme of the present invention's employing is:
A kind of laminated rubber bases; Comprise upper connector and lower connecting plate; Described upper connector is positioned at the top of lower connecting plate; Be provided with the pressurized rubber spacer in the described upper connector, be provided with between described upper connector and the lower connecting plate and cut the pressure rubber spacer, the pressurized rubber spacer presses rubber spacer to fix through the steel strand drawknot with cutting.
Described pressurized rubber spacer is the standard stack rubber layer, and promptly rubber thin layer and steel plate lamination are pasted the combination rubber spacer that compacting forms.
The top and bottom of described pressurized rubber spacer are bonded with upper sealing plate and following shrouding respectively, wherein descend shrouding between pressurized rubber spacer and upper connector.
Be provided with the steel strand hole in order to connect steel strand in the described pressurized rubber spacer.
Described cutting in the pressure rubber spacer vertically is inserted with lead for retractable pencil, promptly in rubber, embeds lead rod, cuts the top and bottom of pressing rubber spacer and is bonded with shrouding up and down respectively, and wherein upper sealing plate is between upper connector and pressurized rubber spacer.
Described cutting presses the rubber spacer internal preset steel strand hole to be arranged in order to connect steel strand, and described shrouding place up and down reserves fixed bolt hole, fixes rubber spacer through set bolt.
Described upper connector is the steel bowl-like member; Fixed bolt hole is reserved in the bottom surface; Fix through set bolt and to cut the pressure rubber spacer, the end face of upper connector is reserved with the connecting bolt hole in order to bearing is connected with the basis with structure, and reservation steel strand hole is to connect steel strand.
Described lower connecting plate is a steel plate will, is reserved with fixed bolt hole above it, fixes through set bolt and cuts the pressure rubber spacer, is reserved with the connecting bolt hole in order to laminated rubber bases is connected with the basis with structure, reserves the steel strand hole to connect steel strand.
Described steel strand are flexible member, pass the pressurized rubber spacer and cut the pressure rubber spacer, with the pressurized rubber spacer with cut that to press rubber spacer to socket fixing, the steel strand upper and lower end grips through ground tackle.
Described ground tackle is selected strand tapered anchorage, supporting type ground tackle or male cone type ground tackle for use.
Owing to adopted such scheme, the invention has the beneficial effects as follows:
The lead rubber bearing that bears pulling force provided by the invention, it is cut and presses rubber spacer when earthquake, can produce horizontal distortion, and can bear superstructure load and vertical earthquake pressure.And do the time spent when bearing produces to be drawn; Through steel strand pulling force is passed to the pressurized rubber spacer; Bear the bearing pulling force through the pressurized rubber spacer, can reach the isolating affection of common shock isolating pedestal like this, can guarantee that again neoprene bearing does not destroy when bearing produces pulling force.Simultaneously the pressurized rubber spacer has elasticity preferably, and when vertical geological process, bearing has ductility preferably when being drawn, can reduce the percussion of structure, the protection structural safety.
In addition when this bears reliably that lead rubber bearing is upper and lower to produce relative lateral displacement under geological process; Thereby can in steel strand, produce pulling force and make the compressive strain of pressurized rubber spacer; Pressurized rubber spacer opposing compression just can reduce the upper and lower relative displacement of bearing by the acting in opposition pulling force in steel strand, thereby increases the restoring force of bearing.This invention scheme is simple, easy to make, and construction can better realize the earthquake isolation effect of laminated rubber bases easily, guarantees the safety of structure under geological process, can be widely used in building foundation shock insulation field.
