Described side bar shaped steel is fixedly installed on upper edge inside welded square tube, is provided with sealing between described side bar shaped steel and central sill shaped steel
Band；The lower surface at described support beam two ends is provided with support spring respectively between corresponding welded square tube；Described support beam two
The upper surface at end is provided with shear spring respectively between corresponding welded square tube；The bottom of described waterstop is provided with drainpipe, described
It is provided with header tank, described drainpipe is connected with header tank in support beam.
Further, it is provided with gusset between the upper surface of described rectangular steel tube and side bar shaped steel.
Further, the two ends of described waterstop are provided with card article；Described side bar shaped steel and central sill shaped steel all offer and card
The draw-in groove of bar cooperation；The upper end of described draw-in groove is provided with the first circular groove, and the upper end of described card article is provided with the second circular arc
Connected in star, is provided with circular compression bar between described first circular groove and the second circular groove.When mounted, will stop
The card article of water band is inserted in draw-in groove, then to both sides, circular compression bar is allocated to the first circular arc along the upper end of card article by manipulator
Between connected in star and the second circular groove, circular compression bar is tightly stuck in the first circular groove and the second circular groove
In.Avoid card article to deviate from from draw-in groove, and between circular compression bar and the first circular groove and the second circular groove
For face sealing, more preferably, in installation and Renewal process, circular compression bar propulsion is more prone to sealing effectiveness, will not be because of circular pressure
Tight bar twists and causes poorly sealed, installs and changes more convenient, just can change in the case of not breaking off a friendship.
The beneficial effects of the utility model are：
First, because welded square tube cross section is integral type rectangular configuration, thus decreasing welding job amount, and make entirety
More rigid, eliminate the impact to box house dimensional accuracy for the welding deformation, it is to avoid the feelings that sliding case snaps in weld
Condition.
2nd, shear spring and support spring are used for adjusting bridge flexible dress displacement so that the utility model is prevented from
Damage retractor device when bridge is subjected to displacement, improve the service life of retractor device.
3rd, the utility model enables the ponding on waterstop to timely enter header tank by drainpipe, and by outer
Adapter road discharge, thus preventing accumulation on waterstop for the ponding, thus prevent in the winter time ponding freeze, eliminate in the winter time because
The safety problem that ponding freezes and causes.
Brief description
Fig. 1 is the structural representation of the bridge extension joint that the utility model provides；
Fig. 2 is the cooperation schematic diagram of card article and draw-in groove.
Specific embodiment
Below by specific embodiment and combine accompanying drawing the utility model is described in further detail.
The bridge extension joint that the shown the utility model of Fig. 1-2 provides, including welded square tube 1, support beam 2, cuts
Cut spring 3, gusset 4, side bar shaped steel 5, waterstop 6, central sill shaped steel 7, circular compression bar 8, drainpipe 9, header tank 10, support bullet
Spring 11, the first circular groove 12, the second circular groove 13 and card article 14.This bridge extension joint includes two mirror image settings
Welded square tube 1, two ends be inserted in the side bar shaped steel 5 of 2, two mirror images of the support beam setting in two welded square tube 1 respectively
With the central sill shaped steel 7 being fixed in support beam 2, described side bar shaped steel 5 is fixedly installed on the upper edge in welded square tube 1 inner side, described
It is provided with waterstop 6 between side bar shaped steel 5 and central sill shaped steel 7；The lower surface at described support beam 2 two ends respectively with corresponding square tube
It is provided with support spring 11 between shaped steel 1；The upper surface at described support beam 2 two ends is provided with respectively between corresponding welded square tube 1
