Description

A kind of wind-resistant spherical support of new structure
Technical field
The invention belongs to bridge construction technical field, be a kind of bearing product that can be used for bridge, be specifically related to a kind of wind-resistant spherical support of new structure.
Background technology
Along with Chinese national economy development need, the cable stayed bridge of large quantities of large span, large bearing capacity and suspension bridge in succession start design and build in recent years.Side inside the tower body of these cable stayed bridges and suspension bridge and between beam body outer lateral side, vertically places and installs 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 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 to displacement and perpendicular bridge to displacement simultaneously, and respectively to the demand of corner.
At present, wind-resistant support bridge engineering applied mainly is divided into wind resistance steel support and basin type rubber wind-resistant support two class.Wind resistance steel support and common multidirectional movable ball-type seat structure similar.This type of wind-resistant support comes off in order to seat board in when preventing bearing from vertically placing skids off, need middle base plate structure be designed to close to hemispherical, when making middle seat board convex spherical put into the segment of side seat board, middle seat board mass cg is positioned at segment inside, and adopt spring outside wind-resistant support by middle seat board with have the seat board of segment to strain.So, this structure makes wind-resistant support bodily form both bulk, manufactures with installation process comparatively difficult; In addition, be subject to the pulling force of existing specification spring, rigidity and size restrictions, 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 realize.The flat frictional pair that in bearing, seat board plane side and bearing opposite side seat board plane form, not being in contactless state by during direction across bridge load, there is certain interval centre, and the nonmetal slide plate be embedded in middle seat board plane side may be deviate to drop, and causes flat frictional pair to lose efficacy; Meanwhile, there is gap between flat frictional pair, when beam body direction across bridge swings, friction pair two contact surface easily produces shock, causes the nonmetal slide plate of friction pair to damage.Basin type rubber wind-resistant support is inlaid with rubber tile in pelvic cavity inside, realizes bearing 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; Manufacture the restriction of difficult forming by Big Diameter Rubber plate, basin type rubber wind-resistant support cannot design large bearing capacity bearing; By the restriction of rubber tile compression deformation ability, bearing angle of rotation is less, cannot realize the designing requirement of large corner.
Summary of the invention
The object of the invention is to propose a kind of new structure wind-resistant support, it is huge that this bearing overcomes existing wind resistance steel support structure bulky, the shortcomings such as flat frictional pair easily lost efficacy, and supporting capacity is low; Overcome the basin type rubber wind-resistant support life-span short, turning power is little, the shortcoming that supporting capacity is low; Also to possess light structure compact for this bearing simultaneously, rotates flexibly, and pressure-bearing surface contact closely, uniform force, Path of Force Transfer be simply clear and definite, with bridge with the advantage such as life-span and security reliability, can meet the designing requirement of all kinds of bridge engineering.
