Described waterstop member comprises with the two close-connected fixtures of curb girder body end face and is embedded in the waterstop in this fixture, can make like this beam body of waterstop member and both sides connect together, and forms the integral body of a sealing Mi Shui.
As preferably, described waterstop member is an integral body, along described shrinkage joint longitudinal extension direction, arranges, and integral design can improve the sealing dense water energy of waterstop member.
For reducing noise, the impact of the vibration that minimizing bridge floor Vehicle Driving Cycle produces on pontic, between described telescoping member and described waterstop member, filling has damping material, the top of this damping material and the bottom of described comb plate are directly or indirectly affixed, the both sides of this damping material directly or indirectly contact with the beam body of both sides, shrinkage joint respectively, and the relative beam body of this damping material is fixed.
Further, between described comb plate bottom and described damping material top, stainless steel dust excluding plate is being set, can preventing from filthyly by the gap on comb plate, falling in damping material, the while also can protect damping material to avoid the direct infringement of ultraviolet ray, travel fatigue etc.
As preferably, described stainless steel dust excluding plate one end is fixed on the floor of a side comb plate bottom, and the other end becomes to arc lower after extending to the rib edges of comb plate bottom of opposite side, during stretching motion described in stainless steel dust excluding plate prolong the downward slippage of described floor.
Described anchor device comprise floor, the anchor slab that is fixedly installed on respectively described comb plate both sides and be fixedly connected on anchor slab and beam body between dowel, can make telescoping member firmly be connected with bridge beam body, and can do with beam body the displacement of vertical and horizontal.
Compared with prior art, the utility model has the advantage of: telescoping member and waterstop member are Split type structure, and waterstop member separation is arranged under telescoping member, be not hit and the crucial Effects of Factors that damages such as sunshine shining directly, long service life, all types stretching device before sealing performance is better than; When telescoping member damage needs to change, without change waterstop member simultaneously, can make the maintenance of expansion gap device convenient, maintenance cost reduces, simultaneously Split type structure design can reduce driving vehicle and act on vibration that top telescoping member the produces impact on waterstop member, extends the application life of waterstop member; The telescoping member on top is modular structure, during installation, by the fixing module of stretching that forms of assembling parts, then a plurality of flexible modules is installed in the reserved notch in shrinkage joint of mounted waterstop member, and installation, maintenance is all very convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of modular closed type bridge expansion joint installation in the utility model embodiment;
Fig. 2 is the enlarged drawing of A part in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, 2, a kind of modular closed type bridge expansion joint installation, comprises the telescoping member 2 being arranged on bridge expanssion joint 11 and is arranged on the waterstop member 3 that telescoping member 2 ,Yu both sides, bottom bridge beam body 1 end faces are close to.Telescoping member 2 is Split type structure with waterstop member 3, wherein telescoping member 2 comprises a plurality of flexible modules 21 of arranging side by side by the width of bridge 1, as in Fig. 1 being 4 flexible modules 21, each flexible module 21 comprise be arranged on the comb plate 211 on 11 surfaces, shrinkage joint and be arranged on comb plate 211 and beam body 1 between anchor device, this anchor device comprise be separately fixed at floor 212, the anchor slab 213 of comb plate 211 both sides and be fixedly connected on anchor slab 213 and beam body 1 between dowel 214.Waterstop member 3 comprises with the two curb girder body close-connected fixtures 32 of 1 end face and is embedded in the waterstop 31 in this fixture 32, can make like this waterstop member 3 and the beam body 1 of both sides connect together, form the integral body of a sealing Mi Shui, and waterstop member 3 is an integral body, along shrinkage joint, 11 longitudinal extension directions arrange, when waterstop member 3 damages, conveniently it is changed like this, and integral design can improve the sealing dense water energy of waterstop member 3.
