The isolation measure of domestic and international employing can be divided into two classes: neoprene bearing shock insulation and sliding and shock isolation.
The former is generally between multilayer rubber presss from both sides with steel sheet, and central authorities add lead for retractable pencil.This structure can lengthen house natural vibration period, makes its remotely seismic wave eigenperiod, reduces geological process, and tool auto-reset function.But its shortcoming is also fairly obvious: because main functionality i.e. vertical carrying and the horizontal shear of this system bearing is all realized by rubber with reset, therefore require should take into account above-mentioned functional realiey in the processing and fabricating of rubber compounding and neoprene bearing shock insulation, its difficulty is very big, is difficult to obtain effective guarantee.The neoprene bearing shock insulation applying to engineering practice has at present exposed many problems, comprises applying to the so important building of airport building and also having occurred many problems.
That the sliding component of low friction and locating part etc. are set at positions such as basis or interlayers in the latter's tradition sliding and shock isolation technology, seismic energy is effectively limited to top transmission and lower portion feedback by Relative sliding motion and friction energy-dissipating, but technology only by friction energy-dissipating and without other power consumption mode, can damage locating part when during its earthquake, displacement is excessive, need to arrange resetting-mechanism separately simultaneously, difficulty of construction is large, and current popularization situation is undesirable.
Rubber earthquake isolation support is only 10 to 15Mpa because design pressure is little, use in highrise building at present and must solve large-scale rubber earthquake isolation support process issues, particularly the not yet done and final product level of the vulcanization of rubber is to the problem of Performance Detection, in the face of producing and checking all difficulties, ensure that product quality has just been not sure.In addition highrise building tilting force when earthquake is large, and rubber earthquake isolation support will face the tensile stress of 1 more than Mpa, will arrange tensile device separately more than 1 Mpa, difficulty of construction and cost high.As time goes on, the problem of aging of rubber earthquake isolation support will expose further, and the performance parameter of bearing expection will decline to a great extent, by abnormally dangerous during coming earthquake.Because rubber earthquake isolation support is in the effect of large-tonnage pressure always, once occurring that quality problems need by entire building synchronization of jacking up, its operation easier is well imagined, can say and almost cannot change.
utility model content:
The purpose of this utility model is to provide a kind of structure simple, and tension, pressure shock insulation ability are strong, and detachably, it is convenient to change, and quality is good, greatly improves the Self-resetting shock isolating pedestal in the application life of building integral.
The purpose of this utility model is achieved like this:
The utility model Self-resetting shock isolating pedestal, X is had to have to the top of the slippage main body in back-moving spring chamber under upper reset spring chamber and Y-direction and bottom the upper base plate be slidably matched with slippage main body respectively, lower seat board, the X of slippage main body to upper reset spring chamber built with upper reset spring, in slippage main body, relative X has upper flange respectively to the position of the corresponding cavity wall in upper reset spring chamber, upper gathering sill is formed between relative upper flange, the upper guide pad be slidably matched with upper gathering sill is had bottom upper base plate, under the Y-direction of slippage main body, back-moving spring chamber is built with the lower back-moving spring of band second upper junction plate and the second lower connecting plate, in slippage main body, under relative Y-direction, there is lower wing plate the position of the corresponding cavity wall in back-moving spring chamber respectively, lower gathering sill is formed between relative lower wing plate, the lower guide pad be slidably matched with lower gathering sill is arranged at lower seat board top, in slippage main body, relative X has X to kerve respectively to the both sides in upper reset spring chamber, the X coordinated to kerve with slippage main body both sides X is respectively had to drag hook bottom upper base plate, in slippage main body, under relative Y-direction, the both sides in back-moving spring chamber have Y-direction kerve respectively, the Y-direction drag hook coordinated with slippage main body both sides Y-direction kerve is respectively arranged at lower seat board top, X is to upper reset spring chamber, under Y-direction, the quantity in back-moving spring chamber depends on the needs, can be one also can be multiple.
Stainless steel slide plate is housed bottom above-mentioned upper base plate, and lower stainless steel slide plate is equipped with at lower seat board top, and slippage body top, bottom are equipped with polyfluortetraethylene plate, lower polyfluortetraethylene plate respectively.
Above-mentioned X is equipped with X to Dang Kuai Y-direction block to the two ends in back-moving spring chamber under upper reset spring chamber, Y-direction respectively by screw, and upper limit position block, lower position block are equipped with respectively by screw in the two ends of upper guide pad, lower guide pad.
The utility model adopts double glide system and reset rubber shear spring to combine together, initial stiffness is provided by sliding friction pair, guarantee is unaffected under building the effect of carrying at wind, during coming earthquake, by rubbing action earthquake energy, play the effect (damping material also can be set in reset rubber shear spring as perfusion lead for retractable pencil for increasing damping) of damping.By reset rubber shear spring, building integral is set back after earthquake completes.Simultaneously because reset rubber shear spring and upper and lower bottom plate and middle steel plate adopt the spacing mode be connected, also very convenient if there is its replacing of problem.On upper and lower bottom plate, drag hook matches with support body gathering sill, overcomes building and is subject to tilting force, avoid building collapse, is particularly suitable for highrise building and uses.The division of labor of this slippage Self-resetting shock isolating pedestal each member function is clear and definite, and clear in structure is succinct, and quality can effectively be ensured, is convenient to realize producing in enormous quantities simultaneously.
Based on increasing lifting surface area that slippage main body contacts with upper base plate to reduce the local stress of building vertical column, namely building vertical column adopts C30 material as usual without the need to improving rank, slippage body and upper base plate are adopted the pattern of wing plate and back-moving spring is hidden in below wing plate, reach and increase support body and bearing slippage upper base plate contact area, to reduce the local stress passing to building vertical column, realize building vertical column adopts C30 material as usual object without the need to improving rank.
Because vertical bearing capacity is directly born by steel plate and high-strength polytetrafluoroethyl-ne, the physical dimension comparing the shock insulation rubber bearing that can bear same vertical load greatly reduces, it also avoid the large-scale rubber earthquake isolation support vulcanization of rubber not easily to ensure and an aging difficult problem, independently anti-pulling structure, solves the ability of shock insulation rubber bearing and traditional sliding isolated bearing passivity building turning over; Relatively traditional sliding isolated bearing, because this bearing has reset rubber shear spring, efficiently solves traditional sliding isolated bearing and need arrange resetting-mechanism separately, the difficult problem that difficulty of construction is large.
The utility model structure is simple, and tension, pressure shock insulation ability are strong, and detachably, it is convenient to change, and quality is good, substantially increases the application life of building integral.
