Description
Technical field
This utility model relates to bridge auxiliary part field, is specifically related to a kind of bridge expansion joint installation.
Background technology
Bridge expanssion joint: refer to for meet bridge floor deformation requirement, generally between two beam-ends, between beam-ends and abutment
Or in the articulated position of bridge, expansion joint is set.Require expansion joint parallel, be perpendicular to the both direction of bridge axes, all can be from
By stretching, solid and reliable, should smooth out when vehicle runs over, without kick and noise；Want to prevent rainwater and rubbish earth from penetrating into resistance
Plug；Installation, inspection, maintenance, elimination dirt will simple and convenient.Arranging at expansion joint, railing will break with deck paving
Open.The effect of bridge expanssion joint: be that regulation is by the position between the superstructure caused by vehicular load and bridge construction material
Move and connection.The retractor device of skew bridge is once destroyed, and by having a strong impact on the speed of driving, comfortableness and safety, even makes
Become driving security incident.
The position that bridge expansion joint installation is weak owing to being arranged on beam-ends structure, directly bears the work repeatedly of vehicular load
With, it is exposed in the Nature more again, is affected by various natural causes, therefore, retractor device is the portion of repairing fragile, difficult
Position.It is many that retractor device produces damaged reason, mainly has: 1, design inconsiderate, and during design, beam end fails to examine cautiously
Considering, under course under cyclic loading, beam-ends breakage causes retractor device malfunctioning.It addition, Deformation calculation is incorrect sometimes, have employed
Excessive expansion spacing, causes retractor device damaged.2, expansion gap device self problem, retractor device structure insufficient rigidity itself
The component strength of anchoring is not enough, produces destruction in various degree during operation.3, the construction at expansion joint with pour, constructed
Cheng Zhong, beam-ends expansion joint spacing is not completed by design requirement, amplifies artificially and reduce, position angle steel malposition, causes
Make retractor device cisco unity malfunction.So there will be following situations: owing to seam is away from the least, rubbery expansion joint is convex because of extruding of transfiniting
Rise and produce jumping car；Owing to seam is away from excessive, the shearing force under load action and the inertia of vehicle traveling, can stretch loosening
Seam rubber takes orientation angle steel out of, creates another type of jumping car.The jail not of the anchor bar welding of retractor device during construction
Gu, or produce the phenomenon omitting pre-buried anchor bar, cause a hidden trouble to expansion joint itself；During construction, retractor device is installed not
Good, after deck paving expansion joint pour bad, during use, cause expansion joint to be damaged under course under cyclic loading.4, even
Continuous seaming is put the most perfect, in order to reduce expansion joint, a large amount of uses continuous beams or continuous deck.Bridge floor the most just need to be arranged continuously
Seam, arranging of stitching continuously is the most perfect, causes and stitches breakage continuously, and produces bridge floor and jump car.At bridge floor seam continuously, deformation baste
Width and the degree of depth arrange to obtain inadequate specification, the most unified, and this affects continuously the normal work of seam the most to some extent.
Talking about publicly known, object can produce, because of the change of ambient temperature, the situation expanded with heat and contract with cold.Therefore for bridge,
It is necessary for arranging expansion joint between each adjacent bridge floor of the predetermined beam length of each two.Expansion gap device has following bright
Aobvious strong point: one, prevent foreign material and rainwater invasion and attack；Two, the comfortableness of driving is improved, it is to avoid cause traffic thing because vehicle jolts
Therefore；The noise produced when three, reducing vehicle pass-through；Four, globality and the visual effect of bridge floor are improved.At present, existing highway bridge is stretched
Contracting seam device the most all includes the pre-embedded steel slab being fixed in the beam end of both sides, expansion joint, owing to pre-embedded steel slab is spelled by plurality of steel plates
Connect and form, thus its upper surface is the most smooth, be unfavorable for the smooth installation of expansion gap device.
Utility model content
This utility model is aiming at the problem that current bridge expanssion joint installation exists, and proposes a kind of novel bridge and stretches
Contracting seam device, in the bridge floor process of expansion and contraction with abutment, to the spiral shell for being fixed with fishback bracing frame by fishback
