step three, mounting a support:
the support upper plate and the support lower plate are fixedly connected with other structures through support upper connecting pieces and support lower connecting pieces respectively.
Compared with the prior art, the invention has the following characteristics and beneficial effects:
according to the invention, the vertical force and the horizontal force are borne separately, the vertical force on the upper part of the support is borne by the long vertical spring, the short vertical spring and the viscous damper, when the support is initially installed on a structure, the long vertical spring is compressed due to smaller rigidity, and the limiting baffle is ensured to be positioned in the center of the first viscous fluid of the limiting baffle groove and not to be contacted with the limiting baffle groove. The vertical period can be obviously prolonged due to the fact that the long vertical spring is small in rigidity, and vertical shock insulation is achieved.
When the vertical earthquake motion is small, the limiting baffle is located in the center of the first viscous fluid of the limiting baffle groove, the limiting baffle is not in contact with the limiting baffle groove, the position of the limiting baffle is kept unchanged, the upper support plate and the lower support plate vertically move relative to each other, and the energy of the vertical earthquake is dissipated by the first viscous fluid.
When vertical earthquake ground moves greatly, the upper plate of the support and the lower plate of the support generate vertical relative motion, and because the vertical vibration amplitude is large, the limit baffle plate starts to contact with the limit baffle groove, the short vertical spring starts to play a role at the moment, the vertical rigidity of the support is obviously increased, the long vertical spring and the short vertical spring are both greatly deformed, and a large restoring force is generated, so that the limit structure generates large vertical displacement.
In addition, because vertical vibration amplitude is great, the limiting baffle starts to move under the effect of the limiting baffle groove, and then the vertical viscous damper is driven to start to displace, so that vertical energy consumption is realized, and seismic energy is dissipated. Under the condition of large earthquake motion, the energy of vertical earthquake motion is dissipated by the viscous damper, and the viscous damper is connected with the upper part and the lower part by the universal hinge, so that the collision problem cannot be caused. In addition, the support core rod iron can freely vibrate from top to bottom on the slip ring when the support vibrates vertically, and the structure can be guaranteed through the core rod iron and the slip ring to be unlikely to generate too big vertical displacement. The displacement limitation of the upper structure is realized by the core steel rod, the displacement of the upper structure is ensured not to be increased without limit, and the displacement of the viscous damper is ensured not to be too large and damaged. The viscous damper consumes energy and provides a certain restoring force for the upper structure.
The horizontal force is borne by the vertical steel rod, the viscous fluid and the rubber body. The main energy dissipation devices are a viscous damper, a viscous fluid and a rubber body. When the support is initially installed on a structure, the vertical steel bar is positioned at the center of the viscous fluid in the rubber body, and the horizontal period can be obviously prolonged due to the small horizontal rigidity of the support, so that horizontal shock insulation is realized; when the local vibration is small, the upper support plate and the lower support plate are displaced relatively, so that the vertical steel bar is driven to move in viscous fluid, the dissipation of seismic energy is realized, and a certain restoring force can be provided.
When horizontal earthquake ground moved great, the support upper plate took place relative displacement great with the support hypoplastron, and vertical rod iron began to collide with rubber body, and the support level is showing the increase to rigidity, provides great restoring force for the structure to further restrict the displacement of structure, made the structure displacement unlikely too big. In addition, because the rubber body has better energy consumption capability, the earthquake energy can be mainly dissipated by the rubber body under the condition of large earthquake.
The vertical force of the upper part of the support is born by a long vertical spring, a short vertical spring and a viscous damper; the horizontal force is borne by the vertical steel rod, the viscous fluid and the rubber body. The main energy dissipation devices are a viscous damper, a viscous fluid and a rubber body. According to the invention, the purposes of prolonging the period and enhancing the energy consumption capability are realized by separating the vertical energy consumption and the horizontal energy consumption of the support, separating the vertical force bearing and the horizontal force bearing and combining the variable stiffness principle, so that the reaction of the upper structure is reduced, and the purpose of protecting the upper structure is realized. The advantages of prolonging the structural period, enhancing the energy consumption capability and changing the rigidity are organically combined to form a novel shock insulation support. The support can well meet the requirements of different structures by reasonably arranging the vertical stress device and the horizontal stress device; and can satisfy the requirement of various structures vibration deformation through reasonable design, effectively realize the shock insulation.
The invention has simple structure, simple processing technology and easy acquisition and assembly of each part. The stress path is clear, the vertical force and the horizontal force are respectively borne by different parts of the support, and the compression-shear separation can be effectively realized. The vertical rigidity and the horizontal rigidity of the support are adjustable, variable and controllable, so that shock insulation and displacement limitation under different seismic oscillation are realized, the installation is convenient, and the cost performance is high. The invention can be used in the field of civil engineering seismic isolation and reduction. The invention combines the advantages of the rubber support and the linear elasticity of the spring, the variable rigidity of the contact problem and the energy consumption capability of the viscous damper, theoretically, the cycle of the upper structure can be infinitely long, and the complete shock insulation is achieved; and the complete shock insulation under the condition of small earthquake, the good energy consumption capability and the good resetting capability under the condition of medium earthquake and large earthquake are realized. The problem that the rigidity of the shock insulation support is adjustable, variable and controllable is solved, shock insulation and energy consumption are organically combined, and the seismic response of the structure is reduced.
