Larger vertical seismic element becomes the major incentive of structural collapse, compares with the vertical vibration isolation of maturation, and vertical earthquake isolating is also only in the experimental study stage, and is ripe, effectively the three-dimensional isolation technical research is urgent.In recent decades, a large amount of earthquake record sheets are bright, produce stronger vertical seismic motion near earthquake centre and seismogenic fault, and some of them vertical seismic element amplitude meets or exceeds horizontal seismic element.Through to the building seimic disaster census of Tangshan Earthquake and Wenchuan earthquake with to the person's of experiencing personally interview, part building structure collapses in the process of ground motion under vertical and horizontal earthquake action and vertical load acting in conjunction.In Wenchuan earthquake, adopt the School Buildings of reinforced concrete frame structure, because the space, classroom is larger, lacking vertical intercolumniation and support or arrange the structure of pillar aileron, under the large shake effect of vertical component greater than horizontal component, pillar can take the lead in destroying and collapse.The vertical earthquake of larger component becomes the major incentive of structural collapse.Compare with the horizontal seismic isolation technical development, vertical vibration isolation is used ripe, and the vertical earthquake isolating slower development.Every aspect earthquake, horizontal seismic isolation adopts rubber earthquake isolation support, vertically adopts air spring can satisfy the shock insulation rigidity requirement in the overall structure three-dimensional, but isolation structure must add anti-rocking equipment.
At present, shock insulation is mainly that level of isolation is to geological process.When overall structure adopts three-dimensional shock isolation support, because the vertical rigidity of bearing is less, when earthquake occurs, how solves the problem of waving of isolation structure and guarantee that the stability of bearing and safety are the main bugbears that the three-dimensional isolation technology is used.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of three-dimensional shock insulation control device; adopt the wave effect of protected structure under geological process of this three-dimensional shock insulation control method to be effectively controlled; its level can reduce greatly with vertical earthquake response, can effectively protect the safety of structure under geological process.
the utility model is achieved in that and comprises the horizontal seismic isolation layer that is positioned at the building bottom of vertical setting and the vertical earthquake isolating layer of the side of being located thereon, the horizontal seismic isolation bearing is set in the horizontal seismic isolation layer, play level isolation geological process, the vertical earthquake isolating layer arranges the vertical earthquake isolating bearing, play vertical isolation geological process, in described vertical earthquake isolating layer, vertical guiding device is set, horizontal seismic isolation and vertical earthquake isolating are separately positioned in two decks, vertical guiding device is arranged in the vertical earthquake isolating layer, described vertical guiding device and vertical earthquake isolating bearing are level shape in parallel and distribute, under horizontal earthquake action, the horizontal seismic isolation layer has less horizontal rigidity and larger deformability, realize the level of isolation earthquake, under Vertical Earthquake Loads, the vertical earthquake isolating layer has less vertical rigidity and larger deformability, realize isolating vertical earthquake.
Here, vertical guiding device is guideway or other bearing unit.The type device can make the vertical earthquake isolating bearing only produce vertical deformation, has limited simultaneously waving of Seismic Isolation of Isolation Layer, has guaranteed the use of superstructure.
Under the ambient vibration effect, vertical earthquake isolating bearing of the present invention provides less vertical rigidity, and protected building can realize good vibration isolating effect.
Described horizontal seismic isolation bearing adopts General Purpose Rubber shock isolating pedestal or lead-rubber shock isolating pedestal or high-damping rubber shock isolating pedestal or sliding bearing.
Described vertical earthquake isolating bearing adopts air spring or steel spring or thick meat neoprene bearing.Can adopt air spring when the isolation earthquake, can adopt Steel spring bearing or thick meat neoprene bearing when the isolation vertical motion.
In order to guarantee that the vertical earthquake isolating bearing has enough dampings, the vertical earthquake isolating layer disposes the vertical damping device, and the vertical damping device is displacement type or velocity profile damper.
In order to make described vertical guiding device can ensure that superstructure is along vertical motion, be restricted around waving of horizontal axis simultaneously, at this moment, vertical guiding device should have anti-bending strength preferably, so vertical guiding device is selected bending-resistant type guideway or other congenerous types of devices.
Compared with prior art, the utility model advantage is: (1) three-dimensional shock insulation sets up horizontal seismic isolation layer and vertical earthquake isolating layer, Seismic Isolation of Isolation Layer function singleness separately; (2) the Seismic Isolation of Isolation Layer apparatus structure is simple, and anti-the waving of structure is easy to realize; (3) total cost can reduce greatly.
