The specific embodiment
Consult accompanying drawing 1, the present invention is made up of movable comb plate 1 and fixed fingers plate 2, and the bottom surface of described movable comb plate 1 front end is provided with two chutes parallel with broach 61, is provided with garden cylindricality steel pin 6 in the chute 61, and steel pin 6 and chute 61 are for being slidingly connected; Movable comb plate 1 one ends are fixedly installed on the plural at least tetrafluoro plate rubber bearing 4, and its end is provided with lateral deformation seam 7; The mutual socket joint horizontal of broach of movable comb plate 1 and fixed fingers plate 2 is on stainless steel slide plate 5, and movable comb plate 1 and stainless steel slide plate 5 be for being slidingly connected, and fixed fingers plate 2 and stainless steel slide plate 5 are for fixedlying connected; Described lateral deformation seam 7 is the elastic strip that two steel plate bars, 73 clamping foam plastics strips 72 and polyurethane water-proof sealing compound 71 constitute, and lateral deformation seam 7 is fixedly installed on the rearward end of movable comb plate 1 by steel plate bar 73.
Embodiment 1
Consult accompanying drawing 2 ~ accompanying drawing 3, the present invention installs and construction by following step:
The top layer of required width cutting A beam body 8 and B beam body 9 being installed according to temperature is at that time reserved the concrete of width; digging main muscle, stirrup and the prestress pipe that must not damage when breaking concrete in the beam body; and to protect uncut bituminous concrete; arrangement embedded bar and steel plate; check quantity, should in time supply when damaged.
Deduct the thickness of movable comb plate 1 according to the bridge floor vertical and horizontal gradient, add 2 millimeters height then and determine the end face absolute altitude of three tetrafluoro plate rubber bearings 4, fixing pre-embedded steel slab 42 welding on the base steel plate of tetrafluoro plate rubber bearing 4 and the A beam body 8 with connecting steel plate, then build the intermediate zone concrete eight 2 on the concrete eight 1 and A beam body 8 under tetrafluoro plate rubber bearing 4 bottom surfaces, vibrate to closely knit, treat that concrete strength reaches 50%, monodisplacement tetrafluoro plate rubber bearing 4 can be installed.
According to temperature and the installation width table of comparisons, with the position that two kinds of standard calipers are made anchor bolt 21 on the fixed fingers plate 2 that anchor bolt 21 is fixing with pre-embedded steel slab 22 welding on the B beam body 9, two garden cylindricality steel pins 6 are installed then.Should notice during installation that the chute 61 on garden cylindricality steel pin 6 and the movable comb plate 1 wants corresponding, the accuracy of its position, absolute altitude and verticality also will be considered together in conjunction with the bridge floor vertical and horizontal gradient.After garden cylindricality steel pin 6 is fixing with pre-embedded steel slab 22 welding in the B beam body 9, lay the end socket mould of stiffener net and B beam body 9 ends, water and smash fibrous concrete 91 on the B beam body 9, concrete is answered vibration compacting, control the concrete pavement absolute altitude well, disturbing concrete is installed stainless steel slide plate 5 and fixed fingers plate 2 simultaneously.The at first position perforate of corresponding garden cylindricality steel pin 6 on stainless steel slide plate 5, garden cylindricality steel pin 6 is set in the perforate of stainless steel slide plate 5, tighten the nut on the anchor bolt 21 then, attention garden cylindricality steel pin 6 is used the tape front cover, prevent that concrete binding is to cylindricality steel pin 6 surfaces, garden, build the intermediate zone concrete 92 on the B beam body 9 at last, and the watering covering curing.
Rubber fastening band 3 usefulness screws and steel press strip are separately fixed at A beam body 8 and B beam body 9 sides, follow lifting activity comb plate 1, two chutes 61 on movable comb plate 1 bottom surface are embedded garden cylindricality steel pin 6, the broach of movable comb plate 1 and the mutual socket joint of broach of fixed fingers plate 2 and horizontal are on stainless steel slide plate 5, and the nut 41 that tights a bolt then is fixed on movable comb plate 1 on the tetrafluoro plate rubber bearing 4.
Lateral deformation seam 7 is arranged on the seam crossing of movable comb plate 1 and A beam body 8, one side steel plate bar 73 and the welding of A beam body 8 intermediate zone reinforcing bars, embed garden shape foam plastics strip 72 at seam crossing then, reserve the space of 3 centimeters height on the foam plastics strip 72 and pour into senior polyurethane water-proof sealing compound 71, its end face will be a little less than movable comb plate 1.Construction and installation finish, and treat to get final product open to traffic after maintenance expiration concrete strength reaches standard.
The present invention adopts the structure of the tetrafluoro plate rubber bearing 4 one-sided support activity comb plates 1 of unidirectional activity at a curb girder body, when another curb girder body rotates, can make the phenomenon of movable comb plate 1 front end generation nose, because of its nose amount less, rely on broach top rake way, reach two broach and connect along transition, vehicle is steadily passed through.But the cross spacing mechanism restraint comb plate 1 that garden cylindricality steel pin 6 and chute 61 constitutes and B beam body 9 relative to laterally moving.Lateral deformation seam 7 can satisfy the space of the complex deformation that rotates, vertically rotates and produce during lateral displacement in the plane, can play waterproof and dustproof effect again.
More than just the present invention will be further described, is not in order to limit this patent, all for the present invention's equivalence enforcement, all should be contained within the claim scope of this patent.
