Abstract
The bridge expansion joint device for double-sided flexible bridge includes the first comb plate and the second comb plate separately on the first beam and the second beam on two sides of the expansion joint and at least one support block to support the comb plate via smooth curved surface. The first comb plate and the second comb plate have comb dents crossed mutually. The supported beam has its toothed end moved smoothly without contact with the end of the other beam, and this can avoid the breaking of the comb dents.
Description
Technical field
The present invention relates to a kind of expansion gap device of bridge, especially a kind of bridge expansion joint installation that is used for double side flexible bridge.
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, wherein, movable pecten comprises body and broach, the body of movable pecten is positioned on the bridge expanssion joint, the broach of movable pecten then cooperates with broach on the fixing pecten and is positioned on the beam body, like this, because the stretching motion of bridge is finished by the movable pecten that is arranged on the bridge expanssion joint, there is not vertical transition gap, make bridge floor, road surface connect into an integral body, shockproof properties is good, and vehicle ' is steady, comfortable.As I in first to file, application number is the Chinese invention patent " assemble comb-type bridge extension joint " of 02212134.6 (publication number is CN1384247A).But for double side flexible bridges such as cable stayed bridge, suspension bridges; in the actual use; under other factor effects such as vehicular load, wind-force; during the curb girder body of the Liang Tizhong of both sides, shrinkage joint regular meeting relatively another curb girder body vertical displacement takes place; and the pecten upper comb dent is close to the beam body; there is not vertical gap between the two; like this; the beam end of body can with the broach bottom surface of pecten; produce to conflict, and conflict face is linear, in this case; when vehicle during through this broach that is propped up by the beam end of body, broach is very easily fractureed.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of bridge expansion joint installation that is used for double side flexible bridge at above-mentioned prior art present situation, can effectively avoid the broach of beam end of body and pecten to offset and causes the situation of broach fracture to take place.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this is used for the bridge expansion joint installation of double side flexible bridge, comprise first pecten that is arranged on the first beam body of bridge expanssion joint both sides and second pecten on the second beam body, have at least one to place on the bridge expanssion joint in first pecten and second pecten, first pecten respectively is provided with broach and transpostion interval setting mutually with second pecten in relative separately end, it is characterized in that: have at least one under the broach that is positioned at pecten on the relative beam body on its end, to be provided with rest pad in the described first beam body and the second beam body, and described rest pad is the rounding off curved surface on the surface that contacts with broach.
Because of broach is that the compartment of terrain distributes, described rest pad also is to be spaced apart and arranged under the corresponding broach, like this, because of the pecten of a beam body and Liang Tishang relatively during another beam body generation vertical deflection, because the rest pad on another beam end of body is to the supporting of the broach of pecten on this beam body, the broach of pecten only can be done compliance at the rounding off curved surface of this rest pad and moves on this beam body, and can not come in contact the situation of avoiding the broach of beam end of body and pecten to offset fully with the end of this another beam body.The broach that this design especially is fit to be applied in one of them pecten is across the bridge expansion joint installation on the shrinkage joint of whole bridge.
And all place this bridge expansion joint installation on the bridge expanssion joint for the broach of first pecten and second pecten, when the beam body is made relative vertical deflection, the end of the first beam body and the second beam body all might touch the broach of pecten on the relative beam body, therefore, can all be provided with described rest pad under the broach that is positioned at pecten on the relative beam body on the end of the described first beam body and the second beam body, also be to be respectively arranged with on each beam body in order to support the broach of pecten on the relative beam body.
In the existing bridge, pecten on the beam body by be laid on the beam surface mix being fixed on the beam body of dirt bed, be also to be provided with mixed dirt bed between beam body and the pecten, and this rest pad is set between beam surface and broach, just need to give between beam body and the broach to reserve certain spacing, like this, described pecten does not need to take place fixing by mixing dirt bed and beam body again, promptly can in the described first beam body and the second beam body, have at least one the antidetonation buffer stopper to be set on its surface, and the root of pecten of Liang Tishang that is provided with the antidetonation buffer stopper by screw on this antidetonation buffer stopper, thereby be fixed on the beam surface, and, when beam body generation vertical deflection, by the buffering metamorphosis of this antidetonation buffer stopper, the pecten of the beam surface held stationary that remains unchanged, and displacement can not take place.
Generally, be positioned at a side of pecten in the beam surface, the pitch of laying mixes the bridge deck pavement of materials such as earth, the mixed earth of cement, in actual use, bridge deck pavement is impaired easily, like this, vehicle is the root of punching press pecten directly, pecten is produced serious influence, for avoiding this situation to take place, be provided with a baffle plate between the bridge deck pavement on described first pecten, second pecten and the beam surface separately, this baffle plate generally adopts steel bar, can directly be welded on Liang Tishang, or be embedded in Liang Tishang;
And for reinforcing baffle plate fixing in the beam surface, described baffle plate one side can be fixed with the rectangular leg-of-mutton stiffener in cross section, increases contact area with the beam surface by this stiffener, makes fixing more firm of baffle plate.
When pecten follows that the beam body takes place laterally, during vertical corner reciprocal, for avoiding pecten because of the displacement baffle plate of conflicting, be respectively arranged with elastic material between the described baffle plate and first pecten, second pecten, this elastic material can be various elastomeric materials, as rubber bumper etc., such design also prevents in use simultaneously, and impurity, dirt etc. fall between baffle plate and the pecten and stop up the activity space of pecten, influences the free to deflect of pecten.
Compared with prior art, the invention has the advantages that: by on the end of beam body, under the broach of pecten rest pad is set, the pecten that makes a beam body and Liang Tishang is relatively during another beam body generation vertical deflection, because the rest pad on another beam end of body is to the supporting of the broach of pecten on this beam body, the broach of pecten only can be done compliance at the rounding off curved surface of this rest pad and moves on this beam body, and can not come in contact with the end of this another beam body, can effectively avoid the broach of beam end of body and pecten to offset and cause the situation of broach fracture to take place; In addition, because the setting of this rest pad, the beam surface just no longer needs mixed dirt bed, and comes to take place to fix with the beam body by simple more structure, reduces cost; And pecten and bridge floor are laid the setting of the baffle plate between the layer, and pecten is had protective effect, have avoided the direct punching press pecten of vehicle, and be very practical.
