Abstract

The processing means of common concrete road surface movement joint are to strengthen " rigidity ", and the present invention is, using the method dredged, traffic load to be reached into basic unit；It is characterized in that deformation joint is separated using AB rubber strips, pour and be pounded cammed surface, when rut is by movement joint, the transmission of car lotus reaches basic unit by " angle of flare ", reduces the influence of " rigidity mutation "；AB rubber strips enable AB voussoirs to wriggle up and down, it is ensured that " seam " is in closely connected regular state, reduces the influence of concrete breathing, improves vehicle ride comfort, and the movement joint treatment for making " each side " difficult becomes simple easily, and good management is good to be safeguarded.

Description

The movement joint of cast-in-place concrete road AB voussoir AB rubber strips

Technical field

Road.

Background technology

The most fragile part of concrete road is deformation joint road surface；Movement joint divides again stretches seam and contracting seam, and it is to resist to stretch seam Concrete temperature deforms, and contracting seam is to resist concrete shrinkage deformation；The source of damage is a lot, but is " firm at expansion joint first of reason Degree " mutation, under wheel load impact, occurs " concentrated stress ", and minute crack occurs in concrete, " capillary " phenomenon, concrete occurs Intensity is reduced, more serious crack then occurs, trigger pavement damage；The two of reason are that roadbed also occurs " to concentrate and answer at seam Power ", produces " capillary " phenomenon, and " ponding " occurs, and " ponding " " siphon " occurs under rut impact, and suction is suctioned out and replaced, Gush out ground, be commonly called as " purt mud "；First, two reasons are mutually held mutually, trigger road surface large area to damage；Existing concrete road becomes Shape seam treatment point " flexible " and " contracting seam ", Main Means are the rigidity for improving road surface " plate " " at seam ", complicated cumbersome cost of constructing Height, but " at seam " is still " starting " that road is damaged, and effect " each side " is unsatisfied with.

The content of the invention

Problem, the skill that the present invention takes are damaged in order to the rigidity for overcoming concrete road deformation joint is mutated the road for producing Art scheme is：

Leading thinking is " change block up be thin ", and the basic reason for damaging road surface is traffic load, is dredged vehicle-mounted, presses its " path " Meet concrete material mechanics feature, be delivered to roadbed；

1st, movement joint is regardless of contracting seam and stretches seam, and unified is " movement joint "；Common contracting seam " not revealing the exact details ", is commonly called as " baste ", " false Pitch requirements ratio " stretching seam " spacing of seam " is small, and the present invention sets movement joint by the pitch requirements of " contracting seam ", stitches " saturating " road surface coagulation Soil, spacing 5M or so；

2nd, " section " profit retention " cammed surface " of deformation joint, when rut is by the side for staying cammed surface road, the transmission of car lotus Normal load transfer spreading angle can be pressed, car lotus is reached into basic unit, reduce the influence that " seam " rigidity is mutated road pavement；

3rd, when " cammed surface " at seam is by construction concrete, the rubber strip " separation " completed in advance integrally pours and smashes to be formed；

4th, two sides " cammed surface " of " seam " form " wedge shape " cross section in seam, are filled out " wedge " with concrete；Its reason is, when car lotus During by wedge section, because of the big feature of concrete rigid, load passes to " seam " cammed surface through wedge, " direct " of " rapid " To roadbed；In transmittance process, the concrete of " cammed surface " and " voussoir ", in " pressure " state, avoids concrete shortcoming, plays Concrete advantage；

5th, wedge section is narrow and long, and rigidity is small, " to be segmented ", to improve " rigidity "；Its " intersegmental seam " processes same movement joint, retained The inclined-plane of mutual wedge；Result in formation of two kinds of voussoirs of A and B；Stitched between two voussoirs and apply rubber strip separation, it is jointly whole with pavement concrete Embodiment is poured；

6th, movement joint " waterstop ", the present invention is cried " AB rubber strips " here, and one has been " waterstop " effect, and two is wedge surface to be transmitted Place's " load ", AB rubber strips will have the characteristic of " hardness " high；

7th, AB rubber strips inner face is smooth surface, when concrete road surface micro-is flexible, AB voussoirs be squeezed power when up and down can micro-wriggle, AB rubber strips outside, i.e., to concrete cammed surface side, be distributed " raised line ", and prevention is slided with concrete " cammed surface "；Protect Card AB rubber strips are in regular and closely connected with " seam " state；

Beneficial effect：

1st, concrete transmits vehicle-mounted in the state of " compression ", reduces " rigidity mutation " influence；

2nd, AB voussoirs micro-can wriggle up and down, it is ensured that " seam " is in close-fitting state, reduces the influence of concrete breathing；

3rd, easy construction, once pours and smashes completion；

Specific embodiment：

Example 1, it is specific as shown in drawings, division main points are as follows：

1st, AB rubber strips of the invention are " cloth-like ", simultaneously smooth surface, simultaneously uniform raised line 010；Raised line 010 prevent concrete with Relative " slip " of AB rubber strips and prevent " capillary " phenomenon；Simultaneously smooth surface, can " wriggling "；

2nd, fold first 012 straight, it is desirable to leave " dark machine " in manufacturer's manufacture, can guarantee that AB rubber strips " application " are put down in construction It is suitable, closely connected " board splitter face "；" true seam " is avoided into, causes driving vehicle to vibrate, influence ride comfort；

3rd, concrete shrinkage after constructing, can make AB voussoirs " whereabouts ", have " convex-concave " with road surface, control to reduce as far as possible, can apply During work cast-in-place concrete, AB voussoirs face is poured and smashes height little by little；Can be ground off when staying " many ", stay and " low " with regard to trouble, so " height " is how much prudent；These, will grope in concrete practice；

4th, tackle " temperature becomes ", it is desirable to pour the median that concrete temperature when smashing is in local year temperature；

5th, existing concrete road surface longitudinal direction " contracting seam " is also processed with method of the present invention；

6th, it is fixed according to the requirement such as road surface load for distributed steel requirement, but have some attention, it is ensured that road surface does not produce stress " mutation "；

Another damageable zone of example 2, concrete road is road " rut " road surface nearby, and reason is concrete road surface " by curved Square ", caused by " arch camber " " warping " deformation；" bulk " road surface can be become into " fritter " with present invention segmentation road surface, produce rut " moment of flexure " diminish, " arch camber " and " warping " diminishes, reduce damage phenomenon；Certainly, this way will fully be tested in the present invention Card, the implementation selection that situation about working well is made；

One of example 3, municipal concrete road damageable zone are at sewer manhole lid；AB rubber strips of the invention can be used " well lid " position is separated out, makes well lid position into " reverse wedge shape " square plate, stayed lifting hole and square plate structure reinforcing bars, and road Face cast-in-place concrete together, pours and smashes that rear AB voussoirs are movable, and square plate is movable, and real inspection well head is in concrete road surface Bottom；So, when vehicle is by square plate, " stress concentration " phenomenon " will not be collided " and is produced, eliminate well lid " problem "；

Implementation result：

1st, movement joint seam small, the vehicle ride comfort wide of cast-in-place concrete road AB voussoirs and AB rubber strips；

2nd, simple expense of constructing is low, and good management is good to be safeguarded.
