Description
Technical field
The utility model relates to a kind of bridge pad, relates generally to a kind of elasticity wind resistance benzvalene form bridge pad that is applied to cable stayed bridge and suspension bridge.
Background technology
Cable stayed bridge is one of most popular bridge type of China's long-span bridge beam, so far China build up or the cable stayed bridge of Hot work in progress have 30 surplus seat, be only second to Germany, Japan, occupy the third place in the world, and the quantity of striding the footpath concrete deck cable stayed bridge greatly ranks first in the world.Suspension bridge is one of principal mode of large span bridge, and when striding the footpath greater than 800m, the suspension bridge scheme has very big competitiveness.And at present, founded a capital or adopt horizontal wind-resistant support substantially at cable stayed bridge of building and suspension bridge, reserve appropriate gap at the horizontal slide surface (being between tetrafluoro slide plate and the corrosion resistant plate) of wind-resistant support usually and satisfy the lateral displacement requirement.Its effect is a restraint beam body lateral displacement, opposing is rocked because of the beam body of wind-force or seismic forces generation, also to satisfy the transversal stretching displacement request that beam body Yin Wendu produces simultaneously, 1., but adopt such scheme to have two defectives: owing between tetrafluoro slide plate and corrosion resistant plate, exist the gap all the time, when producing transverse wind or seismic forces, to produce directly bump between tetrafluoro slide plate and the corrosion resistant plate, frequent bump will chew the tetrafluoro slide plate, and will be quite unfavorable to the functional performance of bearing.2., each parts is in a kind of free state relatively, inner components is loosening easily, the copper sealing ring of pot bearing particularly, in case loosening, will lose sealing effectiveness.
Summary of the invention
The purpose of this utility model is to provide a kind of elasticity wind resistance benzvalene form bridge pad that is applied to cable stayed bridge and suspension bridge.Adopt the utility model can guarantee that tetrafluoro slide plate and corrosion resistant plate are in close contact condition all the time, avoided direct impact damage between tetrafluoro slide plate and the corrosion resistant plate, can effectively solve the loosening problem of inner components simultaneously.
Elasticity wind resistance benzvalene form bridge pad, comprise the basin seat of fixedlying connected, the slide plate body that is fixedly connected on the bridge main tower barricade, the corrosion resistant plate that is set in turn in slide plate body opposite side and tetrafluoro slide plate with the bridge box and beam backing plate, it is characterized in that: be provided with intermediate plate between basin seat inner bottom part and the tetrafluoro slide plate, be provided with elastic device between intermediate plate and the basin seat inner bottom part.
Described elastic device comprises disk spring, rebound and rubber tile, and the contact surface driving fit between rebound, rubber tile and the intermediate plate is in the lateral clearance of described disk spring between rebound and basin seat inner bottom part.
Described tetrafluoro slide plate is inlayed and is bonded in the seam of intermediate plate; The basin of described basin seat is along being with baffle ring, and the basin of baffle ring by regulating bolt and basin seat be along fixedlying connected, and the interior bayonet socket of baffle ring is buckled on the flange that the cross section is "T"-shaped intermediate plate.
Tetrafluoro slide plate outer periphery is equipped with sealing ring.
The cross sectional shape of described rubber tile is "T"-shaped.
Be with copper sealing ring on the flange of described rubber tile.
The slide plate body can be fixedlyed connected with the bridge main tower barricade by pre-embedded steel slab.
Advantage of the present utility model is:
1, utilizes the elastic force of disk spring, eliminated the lateral clearance between tetrafluoro slide plate and the corrosion resistant plate, lateral clearance is arranged on basin seat inside, avoided the horizontal force that produces because of transverse wind or seismic forces direct impact damage, and solved the particularly loosening problem of copper sealing ring of each component the tetrafluoro slide plate.
2, because bearing inside is provided with elastic device and rubber tile, so bearing is in flexible stress all the time, whole fatigue resistance of bearing and impact are better.
3, eliminated lateral clearance between tetrafluoro slide plate and the corrosion resistant plate, be convenient to sealing ring is set, made the tetrafluoro slide plate be in the seal protection state all the time, prolonged the application life of tetrafluoro slide plate in tetrafluoro slide plate periphery.
4, lateral clearance can be regulated according to actual demands of engineering, makes things convenient for bridge design.
Description of drawings:
