Description
Technical field
The utility model belongs to the bridge extension joint technical field, relates in particular to a kind of fast-assembling slip-off preventing and is prone to change stretching device.
Background technology
The special-purpose stretching device birdsmouth of present existing railroad bridge is positioned at the shaped steel medial surface; The gridle of water proof rubber band is embedded in the birdsmouth of shaped steel, because its structural reason, when the contraction of beam body stretches stretching device; The gridle of water proof rubber band is easier in the birdsmouth of shaped steel, deviate from; Cause the water proof rubber band to come off, and the position that comes off causes drainage, waterproof effect is poor.When the elongation of beam body made the shrinkage joint compression, the water proof rubber band was squeezed, and the middle part sinks, and causes and can not clear up rubbish in the rubber strip automatically.Cause the damage of water proof rubber band and shaped steel, aging speed to accelerate, the later maintenance workload is big.In order to solve the problem that gridle is deviate from easily; The external diameter of gridle is slightly larger than the internal diameter of birdsmouth or with reserving a circular hole in the gridle; After the installation hard cylinder is inserted in the circular hole, like this, in the birdsmouth of shaped steel, deviate from though can prevent gridle; But difficulty is very big when installing, and can not realize more changing jobs of water proof rubber band.
The utility model content
The problem that the utility model will solve just provides a kind ofly installs fast-assembling slip-off preventing convenient, that difficulty comes off, replaceable, good water-proof effect, the extruding of water proof rubber band can be cleared up rubbish in the seam automatically and is prone to change stretching device.
For addressing the above problem; The technical scheme that the utility model adopts is: comprise that being arranged at beam seam two ends has the shaped steel of birdsmouth and the water proof rubber band that both sides have gridle; Gridle is embedded in the birdsmouth, and described birdsmouth is the inverted trapezoidal structure that opening makes progress.
Its additional technical feature is: the inwall side of said birdsmouth is provided with pawl, and gridle is provided with the barb-like groove that is complementary with pawl; The inwall side of said birdsmouth is provided with semicircle groove, and gridle is provided with the semicircle boss that is complementary with this semicircle groove; Described gridle is provided with at least one through hole; Described through hole is two; The cross section of said through hole is circle or rhombus; The cross section of said water proof rubber band is single or a plurality of hexagons and/or circular composite unit structure; Described hexagonal structure comprises regular hexagon structure and parallel hexagonal structure; The wall thickness of said gridle and water proof rubber band junction is equal to or greater than the wall thickness of water proof rubber band; The height in the said shaped steel outside is equal to or higher than the height of water proof rubber band.
The fast-assembling slip-off preventing that the utility model provided is prone to change stretching device compared with prior art; Have the following advantages: one of which; Because birdsmouth is the inverted trapezoidal structure that opening makes progress, and is positioned at the shaped steel medial surface than birdsmouth and compares, birdsmouth is connected tightr with gridle; Better tightness, installing and replacing is convenient; Its two, the inwall side of birdsmouth is provided with pawl, gridle is provided with the barb-like groove that is complementary with pawl, the inwall side of birdsmouth is provided with semicircle groove, gridle is provided with the semicircle boss that is complementary with this semicircle groove.When stretching, the barbed protuberances of pawl is stuck in the barb-like groove, and the semicircle boss is stuck in the semicircle groove, thereby increases the resistance of going out of gridle, prevents that gridle from skidding off in birdsmouth; Its three, gridle is provided with through hole, then the size in the gridle cross section size that equals the birdsmouth cross section gets final product, when gridle inserted birdsmouth, through hole crimp made gridle be very easy to get into birdsmouth, installs more quick and convenient like this; They are four years old; The cross section of water proof rubber band is the composite unit structure of single or a plurality of hexagons, circle or a plurality of geometries; Make the water proof rubber band have the multilayer flashing ability; Waterproof ability is strong, and upper surface basically flushes with the beam face or a little more than the beam face, can clear up ponding and various rubbish automatically in the water proof rubber band telescopic process; Its five, at the wall thickness of gridle and water proof rubber band junction during greater than the wall thickness of water proof rubber band, the water proof rubber band is by compression the time, this place closely contacts with the shaped steel internal face, pulling force more can bear in this place when stretching, raising water proof rubber band application life; Its six, the height in the shaped steel outside is equal to or higher than the height of water proof rubber band, can adapt to the different demands that slag and no slag track are arranged.
