The object of the present invention is achieved like this: the hyperbolical steel support that is used for engineering structures comprises steel loam cake, SMIS and base, the upper surface of SMIS is the plane, soffit is a hyperboloid, and there are a radius of curvature and the corresponding depression of the bi-curved radius of curvature of SMIS in the central authorities of corresponding base upper surface with it.
In order to reduce the friction of rotating between SMIS and base, between SMIS and base, the polytetrafluoroethylene (PTFE) bed course can also be arranged.
In order to strengthen vibration damping, shock resistance, as a further improvement on the present invention, the hyperbolical steel support that is used for engineering structures of the present invention can also have a static housing, above-mentioned base is installed in the static housing, above-mentioned loam cake passes the square hole of static housing case lid central authorities, flexible vibration absorber between the four sides of the upper cover part in static housing and the static housing is to alleviate the influence of vibration or earthquake.This elastic vibration clamper is arc latch plate, and by four sides or the two sides that are bolted to loam cake, the two ends of outermost latch plate contact with the static housing sidewall.Above-mentioned arc latch plate can also replace with compression helical spring.
In order to resist the displacement that upper component expands with heat and contract with cold and produces, can also be provided with one deck polytetrafluoroethylene (PTFE) backing plate and corrosion resistant plate between the upper surface of loam cake and SMIS and between at the bottom of base and the static housing case.
In order to resist pull out force, as a kind of improvement of the present invention, below loam cake, there is one to have the cavity that the limit is received in reducing, the base top periphery has a chimb, and the top of base is positioned at the loam cake cavity, and the chimb that loam cake is received limit and base top forms concavo-convex tongue and groove interlock.On at the bottom of the static housing case, also have two right angle corner guide rails, the lower limb of base is blocked by the top of guide rail, make the base can only translation between two guide rails, and can between two guide rails, not extract, strengthened the resistance to plucking ability and the antivibration ability of the hyperbolical steel support that is used for engineering structures.
In order to prevent that sand and dust, rainwater from entering its work effect of hyperbolical steel support internal influence that is used for engineering structures, on the static housing loam cake, can there be a circle box sealing plate to be fixed in around the loam cake, the edge of loam cake square hole and the space between loam cake are covered, between the upper surface of the lower edge of loam cake periphery and perimeter, sealing ring can be arranged.
Above-mentioned sealing ring can be trapezoidal sealing ring, and there is trapezoidal groove the inboard of sealing ring, and twice groove is at least arranged on the upper surface, to strengthen its sealing effectiveness, makes sand and dust be difficult to enter.
In sum, the hyperbolical steel support that is used for engineering structures of the present invention has following advantage:
(1) owing to adopt the hyperboloid SMIS, makes that bearing not only transmits pressure, load-carrying ability is strong, have universal rotating function, and rotate curvature and manufacture and design, to be fit to all directions curvature of every requirement of engineering better with actual demands of engineering.
(2) static housing and elastic damping assembly can effectively alleviate vibratory impulse and the earthquake influence to engineering structures, have improved the safety and the dynamic reliability of structure greatly.
(3) the concavo-convex tongue and groove occlusion structure of loam cake and base and the employing of guide rail, make structure have the ability of pull out force of stronger opposing strong wind or typhoon and the pull out force that produces when resisting the construction of major workss such as continuous bridge construction, curved bridge and rack, and have function of seismic resistance.
(4) polytetrafluoroethylene (PTFE) has reduced the friction of structure rotation and displacement.
(5) the hyperbolical steel support that is used for engineering structures has adopted rubber tile and sealing ring, has the better seal performance, and wall has been exempted from the intrusion of sand and dust rainwater.
