Description
Technical field
The utility model is related to a kind of assembled multi-directional deflection comb plate bridge expansion devices, belong to science of bridge building Building technology
Field.
Background technology
Bridge extension joint is the important connecting component between highway, railroad bridge end, the quality and performance of the device
The durability of bed rearrangement bridge will be directly affected.It is another directly to bear since bridge extension joint setting is in beam-ends bridge floor vulnerable area
Various natural environment etches influences, and is twisted relatively during use because there is cold and hot flexible, oscillation in the pitch mode tilting, lateral oscillation
Equal multi-directional deflections（That is, three direction displacement, flexible and rotation）The problems such as.Therefore, include to the general requirement of the telescopic device：It is anti-
Aqueous each component durability that can be in good, capable of expansion and contraction and device is good, especially the overall structure and installation accuracy of telescopic device
Design requirement need to be reached, low noise, vibrations are small when being sailed with sharp vehicle, to realize that telescopic device overall operation is good, use the longevity
Life is long and easy to maintain.
All it is reserved notch before existing highway bridge telescopic device in-site installation, is embedded with anchor rib on the notch, then stretching
Generally C20 concretes is used to be laid with interim expansion joint at contracting slot mouth, then as bridge face is integrally mated formation together on interim expansion joint
Lower layer and pavement asphalt, then layers of asphalt at expansion joint is first cut and removed when installing expansion joint, interim expansion joint is cut, clearly
It manages beam-ends and exposes anchor rib, then deck expansion installation component is gradually installed.Shortcoming is existing for this kind of mounting means：⑴
Each all pitches mated formation at expansion joint and interim expansion joint are required for cutting and abandon, and effect on environment is unfavorable, pitch
And natural resources is largely lost in the needs such as interim expansion joint；(2) cutting and elimination and fill these rubbish and need a large amount of human and material resources
And transport power；(3) expansion joint notch seriously affects bridge floor crossed construction safety and benefit；(4) big, bridge floor is influenced on bridge lower part environment
A large amount of rubbish are easy to fall in joint of bridge when crossed construction and later stage expansion joint installation cleaning pitch and the interim expansion joint of cleaning
Locate on abutment, it is flexible or fall in bridge in the following, be unfavorable for the safety of personnel or vehicle or attachment under bridge to influence bridge, polluted
Ground environment under bridge.In addition, existing comb plate bridge expansion device is using the method for bolt anchoring：First pre embedded bolt, nut
On flexible panel road surface, the counterbore depth of flexible panel only has 15 ~ 20mm deep, and nut stings flight lead from only 12 ~ 17mm, this kind
Shortcoming existing for mounting means is：Under the repeated stock of cargo, nut is easy fatigue and loosens flexible panel, once fall
Plate, screw rod is exposed on runway, is easy to blow out, and generates security risk.
On April 7th, 2017 invention disclosed patent " a kind of unit assembled prestressing force Multidirectional displacement bridge expansion device and
Installation method "（201710223561.1）It is first to be welded on fastener inserts on the anchor rib that both ends are reserved at bridge expanssion joint,
Cast-in-site high-strength concrete makes fastener inserts be respectively linked together with beam-ends at expansion joint again, then tooling cover board is covered flexible
Seam, when being laid with pavement asphalt, tooling cover board plate face and both ends are integrally laid with together with road surface, and pitch cuts chiseler again after completing
Pitch near capping plate simultaneously takes out cover board and gives over to reuse, then branch's assembling telescopic device and with high in fastener inserts
Strong stress screw rod locking.This method is using high-strength stress screw rod and slot hole nut check, and antifatigue impact capacity is strong, installation accuracy
It is high.Pitch is saved, human and material resources and transport power needed for on-site cutting and cleaning is reduced, alleviates the influence to environment, construction period
It greatly shortens, installation process synchronous with roadmarking can carry out, and can be open to traffic clearance after installation completion.However the technical solution exists
In actual mechanical process, when the flexible panel of telescopic device assembles in branch in fastener inserts, since asphalt bridge floor paved
The error of objective reality absolute altitude in journey, the gradient leads to flexible panel absolute altitude, the gradient and bituminous paving absolute altitude, the gradient occur to be difficult to
Adjust consistent technical barrier and the problem of installation speed need further to be promoted.
Invention content
The purpose of this utility model is to be directed to background technology described problem, " a kind of unit assembled pre- to answer in patent of invention
