Description

A kind of resisting super displacement Modular comb type expansion joint installation of girder

Technical field

The utility model relates to a kind of expansion gap device of bridge, particularly a kind of resisting super displacement bridge expansion joint installation.

Background technology

In existing bridge expansion joint installation, adopting fixedly, the comb type stretching device of pecten and the cooperation of movable pecten is a kind of preferably, especially use stroke in the large bridge shrinkage joint more than 160 millimeters, Chinese patent ZL02264872.0 number " assemble comb-type bridge extension joint " formerly proposing as me is exactly like this, because its stretching motion is by placing the movable pecten on the bridge expanssion joint to finish, there is not vertical transition gap, and and bridge floor, the road surface connects into an integral body, therefore shockproof properties is good, vehicle ' is steady, comfortable, avoided jumping car phenomenon effectively, made vehicle smooth-going, cosily cross.

But at cable stayed bridge, suspension bridge, in the bridges such as arc beam bridge, the beam body is except taking place vertically under vehicular load and temperature effect, outside the vertical deflection, under other factor effects such as wind-force, the beam body also can the occurred level direction horizontal corner and wrench deformation, traditional modulus formula and comb type stretching device all can not satisfy this distortion needs, modulus formula device can produce in length and breadth, and beam takes off chain, the bearing fracture, and be that rigidity contacts between the broach of comb type stretching device, under this lateral deformation effect, broach wrecks easily, thereby causes the damage of whole expansion gap device.

Summary of the invention

Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of still can the complete modular comb type bridge expansion joint installation that does not rupture of holding device when especially big horizontal corner reciprocal takes place under because of external force effect such as pneumatic the beam body.

Another technical problem to be solved in the utility model provides and a kind ofly can resist the modular comb type bridge expansion joint installation that beam body lateral deflection again can anti-beam body vertical deflection.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this resisting super displacement modular comb type bridge extension joint, include at least two modules that are arranged side by side by the width of bridge, wherein each module comprises fixedly pecten and the movable pecten that is separately positioned on the bridge expanssion joint two curb girder bodies, wherein movable pecten is cross-placed on the bridge expanssion joint, fixedly pecten respectively is provided with broach and transpostion interval setting mutually with movable pecten in relative separately end, the root that it is characterized in that described movable pecten is connected on the base that is fixed as one with the beam body in relatively turnable mode, the broach of described fixedly pecten then is connected on the root of fixing pecten in rotating mode, simultaneously, fixedly the broach of pecten middle part is arranged on the backing plate that is fixed as one with the beam body in the mode of horizontal cross skew relatively again.

Relatively rotating between described movable pecten root and the base is connected can be in the following ways: the root of movable pecten has protruding cylindrical shaft pivot down, then has corresponding cylindric recess on the base, and by positioning bolt both are connected one in adjacent regions, and, the hole that this positioning bolt of appearance passes on the base is a mounting hole, and this mounting hole is filled with elastic damping material in the gap of positioning bolt both sides; But the flexible bearing of liner also in described cylindric recess bottom is scratched variable force to subdue, is absorbed dissipation vehicular impact power and vibration force; Described positioning bolt can run through described movable pecten and base, and the afterbody step of bolt is or/and the nut surface is dome shape, and base is or/and movable pecten then has corresponding ball-and-socket in the corresponding position, so that whole device can be resisted certain vertical deflection.
