Abstract
The utility model relates to a joint for a bridge end transition slab. The joint end of the bridge end transition slab, which is connected with a bridge, is made into an arc head; stub axles are fixed at the two sides of the joint end; a channel steel is fixed at the contact position of the bridge end transition slab and a capping beam; the two ends of the channel steel are provided with sealing plates. In the installing process, the arc head of the bridge end transition slab extends into a groove of the channel steel and the sealing plates are sleeved on the stub axles of the bridge end transition slab through axle holes and are fixed at the two ends of the channel steel by bolts. In the settling process of a roadbed, the arc head of the bridge end transition slab can rotate out of the groove of the channel steel so as to avoid generating a gap.
Description
Technical field
The utility model relates to a kind of transition slab at bridge head, specifically the connecting device of a kind of transition slab at bridge head and bridge joint.
Background technology
The road surface of highway and bridge are because of the influence of ground gene power, and the stiffness difference of road and bridge, the differential settlement of unavoidable end of the bridge, the sedimentation difference phenomenon that causes.Especially newly the highway of building and the joining place of bridge owing to bigger difference in height occurs, bigger slit occurs between attachment strap and bridge, can cause that this exists hidden peril of accident concerning driving, be unfavorable for traffic safety to jumping the car phenomenon.
Summary of the invention
In order to solve problem of bumping at bridge-head, the utility model provides a kind of transition slab at bridge head joint, and this device is provided with active joint, thereby avoids bridge floor and road surface the slit to occur, has improved the safety factor of driving.
The utility model solves the technical measures that its technical problem takes, the tip side of transition slab at bridge head and bridge is made the arc head, the arc head wraps up with steel plate, the fixing minor axis in the both sides of tip side, at the contact position fixedly channel-section steel of transition slab at bridge head with lid fine strain of millet, the opening of channel-section steel is bridge dorsad, the two ends of channel-section steel arrange shrouding, described shrouding adopts the two ends that are bolted to channel-section steel, and the two ends of channel-section steel arrange the shrouding screw, open axis hole at shrouding, axis hole becomes the ellipse of above-below direction, the installation that matches with the minor axis of transition slab at bridge head of this axis hole, in order to strengthen the intensity at channel-section steel interior angle place, the place arranges reinforcing rib at interior angle, support place, Inner angle, to improve the intensity at place, Inner angle, avoid being bent song, influence the function of connecting device.During installation, the arc head of transition slab at bridge head stretches into the groove Inner of channel-section steel, shrouding is inserted on the minor axis of transition slab at bridge head by axis hole, be fixed by bolts to the two ends of channel-section steel, because the axis hole of shrouding is oval, the minor axis of transition slab at bridge head can move up and down in axis hole, therefore the stress point of transition slab at bridge head joint is on bent cap, rather than on minor axis, downward gravity can act on the bent cap, in order to avoid minor axis is stressed excessive and damage, and the effect of minor axis is to hold vertically moving of transition slab at bridge head, avoids transition slab at bridge head to glide with the sedimentation of roadbed.In the process of subgrade settlement, the free end of transition slab at bridge head is with the synchronous sedimentation in road surface, the situation in slit can appear in the upper surface of transition slab at bridge head and bridge joint, at this moment the camber head of transition slab at bridge head can produce from the groove Inner of channel-section steel, stopping the appearance in slit, thereby reach the purpose that improves safe driving.
The beneficial effects of the utility model are, have improved the safety factor of driving, and are simple in structure.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the member schematic diagram of transition slab at bridge head joint;
Fig. 2 is the structural representation of transition slab at bridge head joint.
Among the figure, 1. transition slab at bridge head, 2. arc head, 3. minor axis, 4. channel-section steel, 5. shrouding, 6. screw, 7. reinforcing rib, 8. axis hole, 9. screw, 10. abutment body, 11. bent caps, 12. bridges, 13. bolts.
The specific embodiment
Among Fig. 1, transition slab at bridge head 1 is made arc head 2 with the tip side of bridge, and the arc head wraps up with steel plate, the fixing minor axis 3 in the both sides of tip side; The two ends of channel-section steel 4 arrange the screw 6 of shrouding 5 and shrouding, in order to strengthen the intensity at channel-section steel interior angle place, at the interior angle place reinforcing rib 7 are set; Open axis hole 8 and screw 9 at shrouding, axis hole becomes the ellipse of above-below direction, the installation that matches with the minor axis of transition slab at bridge head of this axis hole.
Among Fig. 2, bent cap 11 is installed in abutment body 10 upper ends, the fixing channel-section steel 4 in the contact position of transition slab at bridge head 1 and lid fine strain of millet, the opening of channel-section steel is bridge 12 dorsad, the arc head of transition slab at bridge head stretches into the groove Inner of channel-section steel, shrouding 5 is inserted on the minor axis 3 of transition slab at bridge head by axis hole 9, is fixed on the two ends of channel-section steel with bolt 13.
