Chinese patent (application number: 89103848.5) a kind of " bridge expansion joint unit with self-controlled rotary arm " disclosed, this device also be with and stringer will stitch greatly and be divided into some secondary seams, move cross girders with sill bolt side by side and reach flexible purpose.Concrete structure is flexible with pivoted arm and guide upright post control, separates with fixing guide upright post between every cross girders two ends, makes cross girders be in equidistantly parastate; Pivoted arm one end is fixed with the rotation pin, and pivoted arm can rotate around the rotation pin.Have chute in the pivoted arm lower end, every each fixedly connected slip the bolt pin of cross girders two ends, the slip the bolt pin of the same end of cross girders are embedded in the chute below the pivoted arm, and slide therein.1., big seam becomes some cracks this device is compared with the MAVRER shrinkage joint, has just done to adapt to the improvement of China's situation on selection and controlling organization, has reduced cost, still exists weak point on other 26S Proteasome Structure and Function:, it is not steady to drive a vehicle; 2., the structure stiffness is little, vibration is big; 3., many rotatable parts are arranged below the shrinkage joint, lime-ash does not allow to fall, and falls in order not make lime-ash, and secondary seam still needs the people sweep for several times every day; 4., involve mutually between the complex structure, parts, flexible not freely, dumb; 5., can not adapt to bridge both sides temperature difference and different stretching arranged; 6., break down and need stop vehicle pass-through and could keep in repair in a certain position.
The objective of the invention is for avoiding above-mentioned the deficiencies in the prior art part to provide a kind of driving steady, flexible nimbly and freely, need not the special messenger and clean lime-ash, simple in structure, easy to maintenance, do not need extraordinary heterotypic material, cheap, can be with the different alternate inlay type bridge extension seams that have difference to stretch of bridge both sides temperature.
The technical scheme of taking for achieving the above object:
Each is as a whole for two supported boxs of the present invention, places across bridge floor.In supported box, equidistantly be fixed with a diaphragm plate every one.Between two supported boxs and vertical with supported box, evenly, equidistant discharging has extensible canopy.Every adjacent two opposing two ends of extensible canopy are separately fixed on the diaphragm plate of supported box, running roller respectively is equipped with at opposing two ends in addition, and running roller is inserted between the diaphragm plate of supported box, running roller can force supported box to move to carry out roller moving with bridge is flexible, reaches flexible purpose.Be provided with the straight joint up and down that a top is narrow, the bottom is wide between every adjacent two extensible canopies, because the extensible canopy bottom does not have other parts, lime-ash can successfully fall in the lime-ash collecting chamber of extensible canopy bottom from straight joint top.Intersection at supported box and extensible canopy is coated with the wedge-type seal plate, seals on the one hand, and available buffer vehicle wheel load is to the impact force of supported box upper cover plate on the other hand.
The running roller that is contained in extensible canopy one end can also can be single microscler running roller for the paired running roller that is connected as a single entity with axle and screw.
The top seam of the upper and lower straight joint between adjacent two extensible canopies is wide to be 3～15mm, and the bottom seam is wide to be 40～80mm.
Inner lower angle at every diaphragm of supported box is provided with a drain hole.
At the wedge-type seal plate of supported box and extensible canopy intersection, available steel plate is made, and also available rubber tile is made, and the most handy neoprene plate is made.
The present invention's beneficial effect compared with prior art is:
1. the as a whole seam in this shrinkage joint can guarantee that the different driving throughout the year of temperature is steady; 2. this shrinkage joint does not have secondary seam, need not the special messenger and cleans the road surface lime-ash every day; 3. the extensible canopy span at this shrinkage joint is little, and rigidity is big, therefore, vibrates little; 4. because this expanded joint structure is simple, it is flexible to only depend on the rolling of running roller to finish, and frictional force is little, flexible nimbly and freely; 5. because the roller of this flexible roller rest wheel is moving flexible, therefore can bear form because of bridge both sides temperature is different inhomogeneous flexible; 6. one or a few beam of shrinkage joint breaks down, and can keep in repair under normal driving situation; 7. this shrinkage joint can adopt common straightcarbon steel or common low-alloy, high strength steel to make, and need not special type, heterotypic material, and selection is easy, and is cheap; 8. can make of the common process method, processing cost is low.
