Description
Technical field
The present invention relates to the bridge expansion joint installation of a kind of expansion gap device of bridge, particularly a kind of resisting multidirectional displacements.
Background technology
In the existing bridge expansion joint installation, no matter be comb template formula or welding mounted, all bridge expanssion joint is provided with transverse joint plate, and an end of this transverse joint plate is fixed on the Liang Tishang that bridge stitches a side, and the other end is positioned on the beam body of bridge expanssion joint opposite side and can moves relative to this beam body.But in actual use, the beam body is under factor effects such as temperature and wind-force, the horizontal corner and the wrench deformation of meeting occurred level direction, thereby make the horizontal relative translation of generation between transverse joint plate and the beam body, and traditional modulus formula and comb type stretching device all can not satisfy this distortion needs, device can produce supporting beam disconnection fracture in length and breadth, and be that rigidity contacts between the broach of comb type stretching device, transverse joint plate is anchored among the mixed earth on beam-ends surface with expansion bolt, roll under the effect in this lateral deformation and vehicle, broach wrecks easily, thereby causes the damage of whole expansion gap device.
On the other hand, under vehicular load and temperature effect, vertical corner reciprocal also can take place in transverse joint plate, the meeting that degree is serious is damaged whole expansion gap device, such as, for comb template formula, cause broach to wreck easily, diseases such as bearing fracture then can take place for the modulus formula.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of to take place to reverse anyhow under because of factor effects such as temperature and wind-force and during multi-directional deflection at beam body and transverse joint plate at above-mentioned prior art present situation, the bridge expansion joint installation of the resisting multidirectional displacements that do not rupture of still being kept perfectly.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the bridge expansion joint installation of this resisting multidirectional displacements, include and be arranged on the transverse joint plate that bridge is sewed on, first end of this transverse joint plate is fixed on bridge and stitches on the first beam body of a side, and second end is positioned on the second beam body of bridge seam opposite side and can moves relative to this second beam body, it is characterized in that: be provided with under first end of described transverse joint plate and the fixing bottom plate of the first beam body, connect by bolt between transverse joint plate and the bottom plate, and between described transverse joint plate and bottom plate, be provided with intermediate mass, on this intermediate mass, be provided with the plane slide plate.
Wherein, described plane slide plate can adopt polytetrafluoroethylmaterial material, utilizes characteristics such as it is level and smooth, friction factor is low, greasy property is good, makes can be on bottom plate and intermediate mass free level and smooth the moving of transverse joint plate.
Described intermediate mass can simply be folded between transverse joint plate and the bottom plate, but for making transverse joint plate in relative intermediate mass translation process, intermediate mass can be spacing on bottom plate, prevent that the lip-deep plane of intermediate mass slide plate from following intermediate mass too to depart from original position, described bottom plate surface can be provided with the groove that matches with intermediate mass, and described intermediate mass promptly is embedded in the groove of this bottom plate.
For preventing that bridge is under vehicular load and temperature effect, when making transverse joint plate that vertical corner reciprocal take place, expansion gap device to bridge produces damage, below described intermediate mass, can be lined with first elastic insert, increased the preventing vertical corner reciprocal function of bridge like this, make the device can resisting transverse shift, again can preventing vertical corner reciprocal.
Because of often relatively moving between transverse joint plate and the bottom plate, and both by bolt together, the nut cross section at existing bolt two ends is rectangle, be that nut and transverse joint plate and bottom plate contact surface all are horizontal plane, transverse joint plate is when relative bottom plate translation like this, there is certain friction with the contact surface of nut, the displacement and the translation of its result or obstruction transverse joint plate, the perhaps contact surface of worn nut and transverse joint plate, therefore, the afterbody step of described bolt is dome shape or/and the nut inner surface can design, and adopts spherical shape, can reduce bolt, nut and transverse joint plate, the friction of bottom plate contact surface, in displacement that makes transverse joint plate and the suitable more cunning of translation, avoid the wearing and tearing between the parts, helped when vertical deflection the tilt bolt displacement.
For making things convenient for bolt in transverse joint plate and bottom plate, and then they are movable relatively, can have little gap between described bolt and the bottom plate, give the certain activity space of bolt.
For avoid transverse joint plate undue be separated from bottom plate, produce bigger dislocation with bottom plate, can also be provided with bracket between first end of described transverse joint plate and the bottom plate, first end of this bracket and transverse joint plate is fixed as one, bottom plate and bracket then have a pair of lug boss that cooperatively interacts and recess at least, like this, transverse joint plate is the center with this bracket just, does displacement and rotation.
The shape of described lug boss and recess needs only both and cooperatively interacts without limits.
For ease of process and assemble, described lug boss can be on the bracket, i.e. the lobed bottom of bracket, and bottom plate then has corresponding recess.
In order further to strengthen absorbing, anti-seismic performance, between the recess of the bottom of described bracket and bottom plate, can be lined with second elastic insert.
Because of intermediate mass and bracket are being folded between transverse joint plate and the bottom plate side by side, for guaranteeing transverse joint plate displacement and translation more steady on bottom plate, described intermediate mass can respectively be provided with one in the bracket both sides, and described bolt also can be arranged to two, lay respectively at intermediate mass and bracket between.
At this moment, transverse joint plate and bottom plate have two bolt, therefore the activity of transverse joint plate is subjected to bigger inhibition, for the translation space that makes the relative bottom plate of transverse joint plate more strengthens, the cross section of screw can be waist shape on described transverse joint plate and the bottom plate, like this, bolt and with the bracket be the center in waist shape screw along with transverse joint plate displacement, translation, rotate very smooth and easy.
And under the narrower situation of transverse joint plate, the number that is provided with of bolt is restricted, and can only be provided with one, therefore, for guaranteeing transverse joint plate displacement and translation more steady on bottom plate, described intermediate mass can respectively be provided with one in the bracket both sides, and described bolt then runs through the central authorities of bracket.
The transverse joint plate bottom is generally the stainless steel slide plate, promptly is followed successively by from top to bottom: transverse joint plate, plane slide plate, intermediate mass, elastic insert, bottom plate, installation bracket and the first beam body, the direct and transverse joint plate welding of this plane slide plate;
Compared with prior art, the invention has the advantages that: deposit supporting plate by dividing at transverse joint plate, and the between folder is established plane slide plate and intermediate mass, transverse joint plate can be along with the external force free to deflect, when self expanded with heat and contract with cold, its width also can freely stretch, thereby when making beam body and transverse joint plate down multidirectional deformation and relative translation take place because of factor effects such as temperature and wind-force, still can be kept perfectly and not rupture, realize resisting multidirectional displacements; Simultaneously, the present invention also satisfying bridge in vehicular load and temperature effect, makes under the situation of transverse joint plate generation vertical corner reciprocal, impact and vibrations that elastic insert absorbs and subdues vehicle, satisfy the vertical deflection requirement, avoid causing the damage of whole expansion gap device; In addition, the afterbody step of bolt and the design of nut spherical shape reduce the friction of bolt and transverse joint plate, bottom plate contact surface, in displacement that makes transverse joint plate and the suitable more cunning of translation, the wearing and tearing between the parts have been avoided, the inclination displacement of bolt when satisfying vertical deflection.
