Background technology:
At present, super-huge suspension bridge and cable stayed bridge mainly use flexible dress modulus formula and multi-directional deflection interdigitated electrode structure stretching device, wherein modulus formula stretching device almost can not adapt to the horizontal displacement of beam body, and number of patent application be 200410049491.5 and number of patent application be 200610143048.3 to be interdigitated electrode structure stretching devices preferably, but because the broach on the 200610143048.3 movable pectens is positioned on the bridge expanssion joint, when the vertical rotation of beam body generation has displacement, be that movable pecten end carriage end upwarps, at this moment, movable pecten rotation end and nose of comb are not in one plane, form the slope, the strong point is turning cylinder and broach top, it is subjected to the arm of force to be almost movable pecten total length, and broach ruptures easily.Number of patent application is 200410049491.5 to have avoided above-mentioned situation, the restriction of movable plate thickness, and its rotating shaft 3 is because of not too large, its intensity be difficult to guarantee, also each tooth of portable plate only depend on rotating shaft 3 and link to each other, do not have other stopping means, each tooth can be beated during driving, influences traffic safety.
Super-huge bridge such as suspension bridge and cable stayed bridge, the beam body is except can vertically moving under vehicular load and temperature effect, vertically rotating, under other factors effects such as wind-force, multi-directional deflections such as the beam body also can take place laterally to move, lateral rotation and twisting, traditional modulus formula and comb type stretching device all can not satisfy this distortion needs.Tradition modulus formula not only can be because of compressing supporting, pressure-bearing supporting and compression and shear spring aging causes destruction, can producing simultaneously in length and breadth under the external force effect that the beam body causes, beam takes off chain, bearing fracture, the destruction of different situations such as central sill fracture is taken place under vehicle-mounted effect, the above destruction of the sort of situation no matter, all can cause whole stretching device to be changed, maintenance cost is big; Tradition comb type stretching device only has the deflection function of vertically moving, and vertically rotates, laterally moves, multi-directional deflections such as lateral rotation and twisting all can not adapt to, and therefore broach can wreck easily, thereby causes the damage of whole expansion gap device.
The utility model content:
The purpose of this utility model is to provide a kind of bridge with super-large span that adapts to vertically move, vertically rotate because of bridge vehicle-mounted and that temperature Change causes for the deficiency that overcomes the prior art present situation, also to adapt under the other factors effect such as wind-force multi-directional deflection comb-type bridge extension joints such as the beam body also can take place laterally to move, lateral rotation and twisting.
The purpose of this utility model is achieved like this:
The utility model multi-directional deflection bridge extension joint, comprise that first end is connected the first beam body of bridge expanssion joint one side and second end span is got over bridge expanssion joint and taken the transverse joint plate that is put on the second beam body, be fixed on the fixed fingers plate that comb type tooth is arranged on the second beam body, it is characterized in that transverse joint plate is made up of second transverse joint plate that hinged first transverse joint plate of first end and the first beam body and first end and first transverse joint plate, second end flexibly connect, have on second transverse joint plate, second end with the fixed fingers plate on the staggered comb type of comb type tooth tooth.
On above-mentioned first transverse joint plate, second end dovetail groove is arranged, on second transverse joint plate, first end dovetail flange that cooperates with dovetail groove is arranged, the spacing guide pad in the spacing gathering sill that stretches on the fixed fingers plate is arranged on second end of second transverse joint plate.
The restriction transverse joint plate that above-mentioned first transverse joint plate, the first bottom portion is fixed with downward semicircle groove is made the limiting plate vertically move.First limiting plate, be fixed with horizontal rotating shaft at the base plate that is connected with the first beam body, in base plate by the horizontal rotating shaft borehole jack on it on horizontal rotating shaft, the pressing plate that is arranged on the base plate is fixed on base plate on the base plate, in on the base plate with first transverse joint plate, the first bottom portion fixing first limiting plate relevant position on be fixed with upwards second limiting plate of semicircle groove, second limiting plate during vertical rotating shaft is fixed on the base plate makes progress in the semicircle groove, is connected with the vertical rotating shaft Connection Block that is contained in the rotating shaft in the position of first, second limiting plate relatively at first transverse joint plate, first end.
Above-mentioned horizontal rotating shaft hole is a mounting hole, makes middle plate level rotation and makes transverse joint plate do to horizontally rotate and move.
The second above-mentioned beam body is positioned at the bridge expanssion joint place the sluicing groove.
The utility model can adapt to bridge with super-large span because of bridge vehicle-mounted and that temperature Change causes vertically moves, vertically rotates, and can also adapt under the other factors effect such as wind-force, and the beam body also can take place laterally to move, lateral rotation and twisting etc.
