Description
Technical field
The present invention relates to the anti-non-bolt comb plate, comb joint bridge extension joint of a kind of low frictional resistance three and installation method, be specially a kind of three anti-non-bolt type comb plate bridge expansion device and installation methods with drain pipe adopting rustless steel composite liner, job site to carry out building block system assembling.Belong to science of bridge building technical field of buildings.
Background technology
Bridge extension joint is that the important connection member between highway, railroad bridge end, the quality of this device and performance will directly affect the durability of bed rearrangement bridge.Owing to bridge extension joint is arranged on beam-ends bridge floor vulnerable area, another directly subject various natural environment etch impact, use procedure inevitably there will be the phenomenons such as cold and hot flexible, overload.Therefore, the general requirement of this retractor device is included: water resistance is good, capable of expansion and contraction and each component good endurance in device, particularly the overall structure of retractor device and installation accuracy require to reach designing requirement, when sailing in order to vehicle, noise is low, it is little to shake, thus it is good to realize retractor device overall operation, long service life and easy to maintenance.Existing highway bridge retractor device includes: board-like Telescopic rubber device or, shaped steel modular expansion device or, fishback or tooth formula retractor device or, non-bolt type retractor device etc., also have the patented technology such as strip steel ball-joint formula (CN105256718A) or chain type (CN102966036B) retractor device open.
The waterproof measure of existing highway bridge retractor device is: the rubber slab tilted by U-shaped rubber slab and two ends in bottom, expansion joint catches the sewage under overhead stream and silt jointly, the rubbish such as the sewage of institute's productive set can only rely on and diffuse out bridge floor outflow or volatilization naturally, the silt immersed then can only deposit for a long time at this place.The weak point of this kind of scheme is: U-shaped rubber slab is easily aging；The rubbish being coated with cannot be got rid of；Bridge stretches and in multi-directional deflection process, inefficacy easily torn by U-shaped rubber slab.
nullComb plate type bridge extension joint disclosed in Chinese invention patent " comb plate bridge expansion device " (201010595118.5) and " a kind of non-bolt fishback retractor device " (CN201410344085.5)，It is by the fixed fingers plate being connected in bridge expanssion joint both sides、The support member of mobile fishback and each fishback bottom、Anchoring pieces etc. are constituted，Wherein the comb bottom of fixed fingers plate is horizontal slide plate，Horizontal liner plate is arranged at horizontal slide plate bottom，Each fixed fingers plate and each mobile fishback form a width and are about the telescopic unit of 1m，After multiple telescopic unit transverse direction assembly，By welding、Cast in situs shapes，Become the integral telescopic device of bridge，The method of these telescopic units of on-site consolidation is: first by the fixed fingers plate in single (or multiple) telescopic unit and mobile fishback respectively by the dimensional requirement of its final shaped state，It is placed on the bridge floor of bridge end，Successively the anchoring piece in these telescopic units and bridge built-in fitting reinforcement welding are connected again.Its weak point is: have bigger deformation even warping phenomenon before welding afterwards due to telescopic unit, and the retractor device overall precision error after causing these Assemblings and building setting is at least cm level, to reach mm class precision, then is difficult to realize.
In sum, existing comb plate bridge expansion device, all exist U-shaped rubber groove spot can not dredge, the big cracky of liner plate frictional resistance, the problems such as positioning precision is low behind on-the-spot integral installation location.Owing to bridge is impacted by car load, when retractor device integral installation precision is low, this space operation certainly will be further exacerbated by that retractor device is overall and the rate of decay of related accessories, if can not on-call maintenance, then have influence on bridge overall durability energy, shorten the uptime of bridge.
