Description
Technical field
The invention belongs to bridge construction technical field, is a kind of bearing product that can be used for bridge, is specifically related to a kind of rotating mechanism of wind-resistant spherical support.
Background technology
Along with Chinese national economy development need, the cable stayed bridge of large quantities of large spans, large bearing capacity and suspension bridge in succession start design and build in recent years.Between the side of the tower body inner side of these cable stayed bridges and suspension bridge and beam body outer lateral side, vertically place installation wind-resistant support, bearing respectively with tower body and the anchor connection of beam body.Wind-resistant support can limit the large distance of the beam body direction across bridge being caused by wind-force or seismic forces and swing, and bears the transverse horizontal power that beam body transmits, and can meet the direction across bridge displacement of beam body, vertical bridge simultaneously to displacement and perpendicular bridge to displacement, and respectively to the demand of corner.
At present, the wind-resistant support of applying on bridge engineering is mainly divided into wind resistance steel support and basin type rubber wind-resistant support two classes.Wind resistance steel support and common multidirectional movable ball-type seat structure are similar.This type of wind-resistant support when preventing that bearing from vertically placing in seat board skid off and come off, middle base plate structure need be designed to approach hemispherical, while making the protruding sphere of middle seat board put into the segment of a side seat board, middle seat board mass cg is positioned at segment inside, and adopt spring from wind-resistant support outside by seat board and the seat board tension that has segment.So, this structure makes the huge heaviness of the wind-resistant support bodily form, manufactures and comparatively difficulty of installation process; In addition, be subject to pulling force, rigidity and the size restrictions of existing specification spring, above-mentioned wind-resistant support can only meet the requirement that direction across bridge bearing capacity is less than 10000kN, and more the wind-resistant support of large bearing capacity can not be realized.The flat frictional pair of seat board plane one side and bearing opposite side seat board plane composition in bearing, in the time not being subject to direction across bridge load in contactless state, there is certain interval centre, and the nonmetal slide plate being embedded in middle seat board plane one side may be deviate to drop, and causes flat frictional pair to lose efficacy; Meanwhile, have gap between flat frictional pair, in the time that beam body direction across bridge swings, friction pair two contact surfaces easily produce shock, cause the nonmetal slide plate of friction pair to damage.Basin type rubber wind-resistant support is inlaid with rubber tile in pelvic cavity inside, is realized and is born horizontal reacting force and bearing rotating function by rubber tile compressive strain; The easy ageing hardening of elastomeric material, even ultimate failure, makes bearing lose carrying and rotating function, can not ensure the safe handling of bearing and bridge; Be subject to Big Diameter Rubber plate to manufacture the restriction of difficult forming, basin type rubber wind-resistant support cannot design large bearing capacity bearing; Be subject to the restriction of rubber tile compression deformation ability, bearing angle of rotation is less, cannot realize the designing requirement of large corner.
