Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
The embodiment 1 of retractor device of the present utility model with decrease of noise functions：As shown in Figures 1 to 4, retractor device by
Two expansion joint components form to dress, as shown in figure 3, the first expansion joint component 1 and the second expansion joint component 2 or so arrangement, two
Side is alignd, spaced apart between two expansion joint components, forms the gap 8 at expansion joint, the size in the gap 8 is according to bridge
Deflection and the aspect of vehicle stability two considered, typically no more than 8 centimeters.
Expansion joint component includes crossbeam 3, and crossbeam 3 is vertical platy structure, and its connecting side is connected with bridge end, and it deviates from bridge
The top of the side of beam is connected with side bar 4.Side bar 4 includes upper plate 41 and lower plate 42, and wherein lower plate 42 is formed in one with crossbeam 3
Structure, L-shaped or the structure of similar angle steel are formed, crossbeam 3 is vertical, and lower plate 42 is laterally, lower plate 42 is to away from the side of bridge
Overhang, the power that lower plate 42 is born can be directly passed to crossbeam 3.Upper plate 41 is platy structure, is welded on the upper side of lower plate 42
On, upper plate 41 away from the side of bridge be waveform, when upper plate 41 is superimposed with lower plate 42, the wavy edge of upper plate 41 with
The upper surface of lower plate 42 forms corrugated groove, dress is formed in the first expansion joint component 1 and the second expansion joint component 2 flexible
During the gap 8 of seam, the wave shape groove 5 forms the air in gap 8 can be exhausted exhaust passage, i.e., the groove be from
The groove of the upper side that side bar 4 is extended to away from the surface of the side of bridge of side bar 4.The side bar 4 of both sides makes one in arrangement
The crest of the wave shape groove 5 of side is relative with the wave trough position of another wave shape groove 5, so that the waveform of two side girders 4
Groove 5 surrounds gap uniformity, with ensure as far as possible vehicle by when ride comfort.
The downside of crossbeam 3 is welded with tooth plate 6, and tooth plate 6 is at crossbeam 3 to the gap 8 formed between two expansion joint components
Middle extension, the distance of extension are the half of the width of gap 8, and the tooth plate 6 per side has multiple and along the length side of expansion joint component
To interval setting, the tooth plates 6 of both sides to the gap 8 of centre extend when be interlaced arrangement.
The bottom of crossbeam 3 is simultaneously welded with framework 7 in the side of the close bridge of crossbeam 3, and framework 7 is the vertical of rectangle frame composition
Body framework 7, framework 7 is used for support beam 3, and is connected for the embedded bar with bridge, and it is certain that crossbeam 3 is higher by framework 7
Distance, the upper surface of the side bar 4 when this allows for use on crossbeam 3 is concordant with ground, the top of framework 7 and the upper surface of side bar 4
The space that is formed of drop be used for fill concrete and pitch etc., the equal fill concrete in the inside of framework 7, the frame of two expansion joint components
Space between frame 7, between crossbeam 3 and between side bar 4 is the gap 8 at expansion joint, needs filled and process etc. in the gap 8
With attracting noise reduction, water suction, dust-proof, telescopic material.
Bridge extension joint of the present utility model with decrease of noise functions when in use, will weld the first expansion joint of completion
The expansion joint component 2 of component 1 and second is staggered relatively at the installation position of bridge, ensures that both are as far as possible parallel during arrangement, makes side bar 4
Upper side be located at sustained height as far as possible, side bar 4 it is parallel away from the side of the side of bridge, and make the wave of one side side bar 4
The crest of connected in star 5 and the trough of another side are corresponded, and now both tooth plates 6 are submitted in the length direction of expansion joint component
Mistake arrangement, welds together both frameworks 7 and the embedded bar on both sides after arrangement is appropriate, then in framework 7 and frame
Concrete, the material such as filled and process in the gap 8 at expansion joint are poured into a mould at the space of the side of the close bridge of the upper cross-beam 3 of frame 7
Material, to play a part of noise reduction, waterproof and dustproof, sands-proof check, compensation deformation.When vehicle drives through expansion gap device, side bar
Wave shape groove 5 on 4 can mitigate the direct impact of wheel, not only protect concrete without damage, and with reduction noise
Effect, wheel moment by being compressed during the gap 8 at expansion joint to the air in gap 8, side wall of the air along gap 8
Exhaust passage between the upper surface of side bar 4 to be discharged by gas so that wheel is difficult that the air in gap 8 is further compressed,
Caused by avoiding the instantaneous air instant decompression that traditional gap 8 without exhaust passage can not discharge gas and cause wheel to leave
Empty quick-fried phenomenon, reduce the noise pollution that vehicle crosses retractor device.Because retractor device is mainly used for compensating bridge length
Spend the deformation in direction, the width arrangement of the length of retractor device along bridge, can be by multiple flexible when bridge is wider
The mode of device splicing covers the width of bridge.
The embodiment 2 of retractor device of the present utility model with decrease of noise functions：As shown in Figure 5 and Figure 6, in above-mentioned implementation
On the basis of example, in order to meet the requirement of the more aximal deformation value of bridge, two expansion joints can be set up in parallel, pass through wherein one
The position of tooth plate 6 of individual expansion joint component sets supporting plate, and an intermediate member 9, the upper surface of intermediate member 9 are set in supporting plate
Concordant with the upper surface of two side girders 4, the both sides of the upper surface of intermediate member 9 set wave shape groove 5, wave shape groove 5 with
The construction and arrangement mode of wave shape groove 5 in a upper embodiment is identical, repeats no more.
Retractor device embodiment 3 of the present utility model with decrease of noise functions：As shown in fig. 7, it is different from embodiment 1 it
It is in the present embodiment is that thinking institute of the present utility model is combined on the basis of a kind of existing trapezoidal broach expansion gap device
The improvement of progress, circular arc 9 is processed on the tooth of broach, the existing broach end face for there are corner angle is changed into circular arc to reduce
To the impulsive force of wheel, certain noise reduction purpose is played, the junction between the tooth and tooth of broach processes the groove of arc,
As the exhaust groove 5 of noise reduction, the air in gap 8 is discharged in time when being extruded by wheel, avoid generation empty quick-fried
Phenomenon, there is noise reduction.
Retractor device embodiment 4 of the present utility model with decrease of noise functions：As shown in fig. 7, it is different from embodiment 3 it
It is in the present embodiment is the improvement carried out on the basis of a kind of existing rectangle broach expansion gap device, equally in tooth
The exhaust groove of junction open arc shape between tooth, and broach is improved to circular arc, so as to play the purpose of noise reduction.
In other embodiments, the upper plate of side bar and lower plate can be integrated formed structures, including cast or casting
Two ways is machined on the basis of part；Side bar, crossbeam and tooth plate are alternatively integrated formed structure；Exhaust passage both can be recessed
Groove, through hole can also be substituted for；The shape of groove or through hole both can be waveform, also can be replaced zigzag or other are several
What or special-shaped shape；Groove or through hole can be that step groove is alternatively skewed slot；The wave shape groove of two expansion joint components
The corresponding relation of crest and trough also can be replaced crest to crest and trough to trough；The length and shape of tooth plate are also variable
Change, the corresponding relation of both sides tooth plate also can be replaced the mode being oppositely arranged.
