Abstract
The utility model discloses a transition slab device, including transition slab, back support system, shock attenuation spiral, the transmission column of load system, load computational system, hydraulic power system, driving system transmission column, computer control system, abutment bracket. Back support system is through setting up the mutual interlock of recess and halfcylinder control transition slab horizontal displacement, preceding support system is through setting up load computational system, vertical displacement when satisfying vehicle loading transition slab, computer control system and hydraulic power system does not take place, when vehicle loading during in transition slab can produce, the vehicular load passes through load computational system stand and transmits to load computational system, system analysis calculates the imposed load size, communicate the load signal to hydraulic power system through computer control system, hydraulic power system carries out reverse load according to the load size after receiving the signal, the top rises to bridge deck pavement highly on pushing away transition slab, it takes place to avoid the either end of a bridge to jump the car phenomenon.
Description
Technical field
The utility model relates to a kind of highway bridge field, particularly relates to a kind of various standard highway bridge head attachment strap field.
Background technology
River and obstruction can be crossed over unavoidably in highway alignment, need when across obstacle to ensure that route is smooth and easy by the engineering that constructs a bridge, at roadbed and bridge cohesive position, because roadbed belongs to flexible structure thing, bridge abutment belongs to rigid structure, and under load action, end of the bridge there will be differential settlement phenomenon, occurs bumping at bridge-head when sedimentation is larger, concerning driving, there is huge hidden peril of accident, be unfavorable for traffic safety.Therefore need many vehicle bump at bridge ends to improve, invent a kind of novel transition slab at bridge head device and avoid vehicle bump at bridge ends to occur.
Summary of the invention
For achieving the above object, the utility model adopts following technical proposals.
Transition slab at bridge head arranges two groups, front and back support system, front support system comprises spiral shock mitigation system, load computing system, hydraulic power system, computer control system, spiral shock mitigation system is arranged in the middle of load computing system and hydraulic power system, and hydraulic power system is near abutment side.
Rear support system, distance 1.5m position, transition slab at bridge head rear end arranges a diameter 100mm semi-circular recesses, groove medial surface parcel 5mm steel plate, groove bottom is steel concrete Extended chemotherapy, at groove, corresponding transition slab at bridge head place arranges diameter semicylinder consistent with groove diameter, and semicylinder contacts bread with groove and wraps up in steel plate.
Front support system is by spiral shock mitigation system, load computing system, hydraulic power system forms, each runway is uniformly distributed two bearings, spiral shock mitigation system is by high-strength spiral wire, upper lower gasket, cushioning support-saddle forms, when Vehicle Load transition slab at bridge head, transition slab at bridge head produces, vehicular load is passed to load computing system by load computing system column, system analysis computation load also produces load signal, by computer control system, load signal is conveyed to hydraulic power system, hydraulic power system carries out Opposite side loading according to load signal after receiving signal, pushing tow transition slab at bridge head rises to deck paving height, vehicle bump at bridge ends is avoided to occur.
Transition slab at bridge head is made up of steel concrete, and cross section, termination adopts steel plate parcel, and protection transition slab at bridge head end cross-sectional, stays 20mm gap between transition slab at bridge head and abutment, ensures that transition slab at bridge head moves up and down and has sufficient space.
The utility model advantage and effect.
Vehicular load is passed to load computing system, by computer control system, load signal is conveyed to hydraulic power system, hydraulic power system carries out Opposite side loading according to load, pushing tow transition slab at bridge head rises to deck paving height, vehicle bump at bridge ends is avoided to occur, thorough solution abutment and embankment joining place jump car, travel with making vehicle energy high-speed smooth.
