Description
Technical field
The utility model belongs to road and bridge engineering technical field, relates to a kind of Highway-bridge Expansion Joints structure.
Background technology
Bridge expanssion joint refers to the requirement for meeting bridge floor distortion, usually between two beam-ends, between beam-ends and abutment or in the articulated position of bridge, arranges shrinkage joint.Shrinkage joint generally will meet should be able to free-extension in the both direction of parallel, vertical bridge axle, but when bridge run-off the straight bends, the loaded plate on shrinkage joint can tilt side, affects vehicle and passes through, be therefore necessary to improve.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides one and can eliminate road and bridge diastrophic Highway-bridge Expansion Joints structure.
The purpose of this utility model realizes by following technical proposal: a kind of Highway-bridge Expansion Joints structure, it is characterized in that: comprise left bridge and right bridge, between left bridge and right bridge, there is gap, and left bridge and right bridge have notch one and notch two with gap joining place respectively, bottom notch one side locations and notch two, rubber pad is fixed with respectively near notch two side locations bottom described notch one, rubber pad has bayonet socket, also comprise junction plate one and junction plate two, described junction plate one and junction plate two are stuck on the bayonet socket of rubber pad, and respectively with notch one bottom and notch two bottom fit, and junction plate one and junction plate two are articulated with gripper shoe one and gripper shoe two respectively by hinge, also comprise loaded plate, described loaded plate bottom surface is fixed with gripper shoe one and gripper shoe two end face respectively, and cover on the gap between left bridge and right bridge.
Left bridge and right bridge horizontal relative displacement is eliminated by rubber pad, and when left bridge and right bridge inclination and distortion, rotate by hinge, gripper shoe one and gripper shoe two are fitted all the time to be fixed on loaded plate, thus avoid loaded plate to tilt, therefore this structure can also eliminate the bending of road and bridge and distortion.
In above-mentioned a kind of Highway-bridge Expansion Joints structure, described rubber pad is fixed with the pre-embedded steel slab be located in left bridge and right bridge respectively.
Therefore rubber pad is connected more stable with left bridge and right bridge.
In above-mentioned a kind of Highway-bridge Expansion Joints structure, between described junction plate one and junction plate two, be also connected with the water proof bag on the gap covered between left bridge and right bridge.
Water proof bag plays the effect of water proof.
In above-mentioned a kind of Highway-bridge Expansion Joints structure, described rubber pad is separately fixed on notch one and notch two by screw, and described loaded plate is fixed with gripper shoe one and gripper shoe two respectively by bolt.
In above-mentioned a kind of Highway-bridge Expansion Joints structure, described loaded plate is curved near the two ends of left bridge and right bridge.
Therefore, when road and bridge Bending Deformation, the arcuate structure at loaded plate two ends can make that vehicle is comfortable to be passed through.
Compared with prior art, the utility model tool has the following advantages:
Left bridge and right bridge horizontal relative displacement is eliminated by rubber pad, and when left bridge and right bridge inclination and distortion, rotate by hinge, gripper shoe one and gripper shoe two are fitted all the time to be fixed on loaded plate, thus avoid loaded plate to tilt, therefore this structure can also eliminate the bending of road and bridge and distortion.

Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, a kind of Highway-bridge Expansion Joints structure of the utility model, comprise left bridge 1 and right bridge 11, between left bridge 1 and right bridge 11, there is gap 12, and left bridge 1 and right bridge 11 have notch 1 and notch 2 14 with gap 12 joining place respectively, bottom notch 1 side locations and notch 2 14, rubber pad 2 is fixed with respectively near notch 2 14 side locations bottom notch 1, rubber pad 2 has bayonet socket 21, also comprise junction plate 1 and junction plate 2 31, junction plate 1 and junction plate 2 31 are stuck on the bayonet socket 21 of rubber pad 2, and respectively with notch 1 bottom and notch 2 14 bottom fit, and junction plate 1 and junction plate 2 31 are articulated with gripper shoe 1 and gripper shoe 2 41 respectively by hinge 42, also comprise loaded plate 5, loaded plate 5 bottom surface is fixed with gripper shoe 1 and gripper shoe 2 41 end face respectively, and cover on the gap 12 between left bridge 1 and right bridge 11.
Further, rubber pad 2 is fixed with the pre-embedded steel slab 15 be located in left bridge 1 and right bridge 11 respectively.The water proof bag 32 on the gap 12 that covers between left bridge 1 and right bridge 11 is also connected with between junction plate 1 and junction plate 2 31.Rubber pad 2 is separately fixed on notch 1 and notch 2 14 by screw, and loaded plate 5 is fixed with gripper shoe 1 and gripper shoe 2 41 respectively by bolt.Loaded plate 5 is curved near the two ends of left bridge 1 and right bridge 11.
