Abstract
A bridge adjustment support comprises a lifting supporting seat, a wedged supporting frame, a wedged elevation block and a rotary push rod. The lifting supporting seat is mounted on the wedged supporting frame, the lower end of the lifting support is provided with a wedged face which contacts with the upper surface of the wedged elevation block, the left end of the rotary push rod contacts with the right side of the wedged elevation block, and the rotary push rod is in threaded connection with the wedged supporting frame. When height of a bridge girder is adjusted, the bridge adjustment support is disposed between the girder and an abutment, the height of the top face of the girder can be adjusted accurately only by simply pushing the rotary push rod to support the elevated girder, and the bridge adjustment support is safe, reliable, timesaving, laborsaving and convenient to operate.
Description
Technical field:
The utility model relates to the road and bridge engineering technical field, relates in particular to a kind of bridge and adjusts bearing.
Background technology:
At present, when the girder of road bridge is simple supported T-beam or freely-supported I type beam, support girder be laminated rubber bearing.On pier, change these laminated rubber bearings, will be with the girder jack-up of its top, and girder is generally 8-10mm by the height of jack-up.Under the connection of wet seam, diaphragm, carriageway plate and bridge deck pavement, the superstructure of pontic has formed an integral body, no matter is which sheet girder of support top, and several pieces girders that all can drive its both sides move up.On pier, even only change a laminated rubber bearing, also want the girder of jack-up multi-disc and even a whole bridge opening.Every girder that upwards rises all will be laid 1-2 ultrathin jack and carry out support top below its end, insert 2-3 piece steel cushion block and support as temporary support.After girder was by jack-up, in jack, hydraulic oil slowly bled back, and meanwhile girder slowly falls after rise.In order to prevent that girder from falling after rise, need the girder that the suitable steel cushion block of timely replacing thickness will rise to prop up.But the technique of this support top girder but exists following problem: when the support top girder, along bridge laterally from an end of pier, operate one by one jack, the suffered pressure of jack is 20-50t, the height of each jacking is 0.1-1.0mm, so that the superstructure of pontic is in elastic deformation all the time.Make girder reach designed top lifting height, often will carry out several jacking programs, change tens times and even up to a hundred steel cushion blocks, need the time of one day and even several days.Its change value of thickness of steel cushion block of mutually changing is all very little, but very large with the frictional force of girder and pier, withdraws from or insert all very difficult.The mode of this support girder is simple and crude, and construction technology is loaded down with trivial details, the deviation of bearing height is large.When the vehicular load of bridge floor was larger, between the strong point of two adjacent steel cushion blocks, the superstructure of pontic easily produced larger shearing force, to such an extent as to occur vertical bridge to cracking.In order to guarantee construction safety, at whole jacking girder and change in the process of former board-like neoprene bearing, bridge floor should suspend traffic, and will forbid that at least also oversize vehicle is current.With regard to the road bridge of urban interchange and the main line of communication, this obviously is difficult to accomplish.
The utility model content:
The purpose of this utility model is to provide a kind of bridge to adjust bearing, solves the defective that road bridge support girder mode is simple and crude, construction technology is loaded down with trivial details, the bearing height deviation is large.
The technical scheme that its technical problem that solves the utility model adopts is: this bridge is adjusted bearing, comprise lifting support, wedge shape bracing frame, wedge shape election piece, rotating push rod, on the wedge shape bracing frame lifting support is installed, the lifting support lower end is lozenges, lozenges contact wedge shape is elected the piece upper surface, rotating push rod left end contact wedge shape is elected the piece right flank, is threaded connection between rotating push rod and the wedge shape bracing frame.When adjusting the bridge girder height, convenient bridge is adjusted bearing and is placed between girder and the pier, only need simply pull rotating push rod, just can adjust exactly the height of its end face, and the girder that rises is propped up.At whole jacking girder and change in the process of former board-like neoprene bearing, the various vehicles on the bridge floor can both normally travel.When changing the former board-like neoprene bearing of simple supported T-beam or freely-supported I type beam, convenient bridge is adjusted seat supports and girder.
The utility model is used for supporting the road bridge girder, and is safe and reliable, time saving and energy saving, easy to operate.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
With reference to Fig. 1, the utility model comprises lifting support 1, wedge shape bracing frame 2, wedge shape election piece 3, rotating push rod 4, lifting support 1 is installed on the wedge shape bracing frame 2, lifting support 1 lower end is lozenges, lozenges contact wedge shape is elected piece 3 upper surfaces, rotating push rod 4 left ends contact wedge shape is elected piece 3 right flanks, is threaded connection between rotating push rod 4 and the wedge shape bracing frame 2.When adjusting the bridge girder height, convenient bridge is adjusted bearing and is placed between girder and the pier, only need simply pull rotating push rod 4, just can adjust exactly the height of its end face, and the girder that rises is propped up.
