The specific embodiment
Consult accompanying drawing 1, the utility model is comprised of movable comb tooth plate 1 and fixed fingers plate 2, and the bottom surface of described movable comb tooth plate 1 front end is provided with two chutes parallel with broach 61, is provided with cylindrical steel pin 6 in chute 61, and steel pin 6 and chute 61 are for being slidably connected; Movable comb tooth plate 1 one ends are fixedly installed on 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 tooth plate 1 and fixed fingers plate 2 on stainless steel slide plate 5, movable comb tooth plate 1 with stainless steel slide plate 5 for being slidably connected, fixed fingers plate 2 with stainless steel slide plate 5 for being fixedly connected with; Described lateral deformation seam 7 is the elastic strip that two steel plate bar 73 clamping foam plastics strips 72 and polyurethane water-proof sealing compound 71 form, and lateral deformation seam 7 is fixedly installed on the rearward end of movable comb tooth plate 1 by steel plate bar 73.
Embodiment 1
Consult accompanying drawing 2 ~ accompanying drawing 3, the utility model is installed in the steps below and is constructed:
The top layer of width cutting A beam body 8 required according to temperature installation at that time and B beam body 9 is reserved the concrete of width; digging while breaking concrete main muscle, stirrup and the prestress pipe that must not damage in the beam body; and to protect uncut bituminous concrete; arrange embedded bar and steel plate; check quantity, should in time supply when damaged.
Deduct the thickness of movable comb tooth plate 1 according to the bridge floor vertical and horizontal gradient, then add the height of 2 millimeters and determine the end face absolute altitude of three tetrafluoro plate rubber bearings 4, with junction steel plate, pre-embedded steel slab 42 on the base steel plate of tetrafluoro plate rubber bearing 4 and A beam body 8 is welded and fixed, then build the intermediate zone concrete eight 2 on 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%, the tetrafluoro plate rubber bearing 4 of monodisplacement can be installed.
According to temperature and the installation width table of comparisons, the position with two kinds of standard calipers are made anchor bolt 21 on fixed fingers plate 2, be welded and fixed anchor bolt 21 and the pre-embedded steel slab 22 on B beam body 9, and then two cylindrical steel pins 6 are installed.Should notice during installation that cylindrical steel pin 6 is corresponding with the chute 61 on movable comb tooth plate 1, the accuracy of its position, absolute altitude and verticality, also will consider together in conjunction with the bridge floor vertical and horizontal gradient.After the pre-embedded steel slab 22 that cylindrical steel pin 6 and B beam body 9 is interior is welded and fixed, lay the end socket mould of stiffener net and B beam body 9 ends, water and smash fibrous concrete 91 on B beam body 9, concrete is answered vibration compacting, control the concrete pavement absolute altitude well, disturbing concrete simultaneously, is installed stainless steel slide plate 5 and fixed fingers plate 2.At first the position perforate of corresponding circle cylindricality steel pin 6 on stainless steel slide plate 5, cylindrical steel pin 6 is set in the perforate of stainless steel slide plate 5, then tighten the nut on anchor bolt 21, note cylindrical steel pin 6 tape front cover, prevent that concrete binding from arriving cylindrical steel pin 6 surfaces, build finally the intermediate zone concrete 92 on B beam body 9, and the watering covering curing.
Rubber fastening band 3 use screws and steel press strip are separately fixed at A beam body 8 and B beam body 9 sides, then lift movable comb tooth plate 1, two chutes 61 on movable comb tooth plate 1 bottom surface are embedded cylindrical steel pin 6, the mutual socket joint of the broach of the broach of movable comb tooth plate 1 and fixed fingers plate 2 and horizontal are on stainless steel slide plate 5, and the nut 41 that then tights a bolt is fixed on movable comb tooth plate 1 on tetrafluoro plate rubber bearing 4.
Lateral deformation seam 7 is arranged on the seam crossing of movable comb tooth plate 1 and A beam body 8, one side steel plate bar 73 and the 8 intermediate zone reinforcing bar welding of A beam body, then embed circular foam plastics strip 72 at seam crossing, reserve the senior polyurethane water-proof sealing compound 71 of space perfusion of 3 centimeters height on foam plastics strip 72, its end face outline is lower than movable comb tooth plate 1.Construction and installation finish, and until maintenance, expire after concrete strength reaches standard and get final product open to traffic.
The utility model adopts the structure of the one-sided support movable comb tooth plate 1 of tetrafluoro plate rubber bearing 4 of one-way movable on a curb girder body, when another curb girder body rotates, can make movable comb tooth plate 1 front end generation nose phenomenon, 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 cylindrical steel pin 6 and the cross spacing mechanism restraint comb plate 1 of chute 61 formations and the relative transverse shifting of B beam body 9.The space that lateral deformation seam 7 produces complex deformation in the time of can meeting Plane Rotation, vertical rotating and lateral displacement, can play again waterproof and dustproof effect.
More than just the utility model is described further, not in order to limit this patent, all is that the utility model equivalence is implemented, within all should being contained in the claim scope of this patent.
