Description
Technical field
This utility model relates to a kind of concrete road surface structure, particularly relates to a kind of assembled be applicable to road engineering
Oblique bond-retarded prestressed concrete pavement structure.
Background technology
In Portland cement concrete pavement structure, owing to concrete material has rigidity greatly, the feature that fragility is big, hold very much
It is easily generated rupture failure.Meanwhile, Portland cement concrete pavement, because of expansion and contraction property, need to build many transverse joints, is handing over
Under logical load action, seam crossing easily causes the diseases such as infiltration, purt mud, faulting of slab ends, plat-bottom escape, differential settlement；Meanwhile, abutment joint
Also need to do substantial amounts of maintenance work, this not only adds the complexity of construction, and reduce road-ability；
Prestressed concrete pavement makes the tensile region of cement concrete pavement in advance by tension reinforcing steel bar Shi Hanzhang
Bear compressive stress, to offset a part of tension produced by vehicular load and variations in temperature, on the one hand, concrete tensile strength
Shortcoming on the low side is made up, and makes concrete crushing strength make full use of, and improves bending tensile strength and the road surface carrying on road surface
Power.On the other hand, prestressed concrete pavement can use little transverse joint to reach surfacing, comfortable requirement of driving a vehicle.
But tradition prestressed concrete pavement presstressed reinforcing steel is longitudinally arranged, and will not produce transverse prestress, under load action, still have
Longitudinal crack may be produced.
When prestressed concrete pavement structure uses the presstressed reinforcing steel having adhesive form, need repeatedly to arrange anchor pier etc.
Counterforce device carries out stretch-draw to reinforcing bar, and work progress is complicated.When prestressed concrete pavement structure uses soap-free emulsion polymeization form
During presstressed reinforcing steel, its effective stretch-draw length is usually no more than 60m, it is desirable to making prestressed concrete pavement plate, is necessary for even
Connect device to be coupled together by presstressed reinforcing steel, so that prestressing force transmission is continuously.Therefore, longitudinal prestressing skill from theory and construction technology
Art is difficult to adapt to concrete road surface large area making.Further, prestressed concrete pavement generally uses cast in situs, construction quality
Can not obtain effective guarantee, it is difficult to realize automatization, mechanized construction, construction period is longer.
Summary of the invention
This utility model is in order to overcome deficiency of the prior art, it is provided that a kind of bearing capacity is high, and can use prefabrication
The mode of on-site consolidation carries out the assembled oblique bond-retarded prestressed concrete pavement structure constructed, and does not the most set up laterally
Seam, thus substantially increase road surface entirety stationarity and driving comfort level, extend the service life on road surface, construction party simultaneously
Just, fast, quality obtains higher guarantee.
To achieve these goals, the technical scheme of this utility model solution technical problem is: the oblique slow cohesion of assembled
Prestressed concrete pavement structure, including rubber water-proof, CA mortar articulamentum and anchor head, it is that it is prefabricated by several
Prestressed concrete pavement plate is mutually inserted composition, each side of described precast prestressed concrete road surface plate and upper end
The adapting position in face is respectively equipped with some opening of the channels and injected hole, and passing hole channel mouth enters slow cohesion to reinforced hole trace interpolation and in advance should
Power reinforcing bar, pours into cement mortar from injected hole.
Described grafting is the connection of the adjacent surface groove being respectively equipped with and the convex key matched.
Described grafting, its seam crossing is provided with rubber fastening band.
Described reinforcing bar duct is to intersect in length and breadth from the inclined direction of opening of the channel to arrange.
Described injected hole communicates with reinforcing bar duct.
Described retarded adhesive prestressed steel bar is additionally provided with anchor head near the outside of precast prestressed concrete road surface plate and enters
Row anchoring.
Described plate lower surface, precast prestressed concrete road surface is additionally provided with one layer of CA mortar articulamentum.
Owing to using said structure so that this utility model compared with prior art has following advantages and an effect:
1, it is that diagonal cross is punctured in the plate of prefabricated prestressed concrete pavement by retarded adhesive prestressed steel bar,
After retarded adhesive prestressed steel bar stretch-draw, road pavement produces the prestressing force in longitudinal and transverse two directions, constrains the double of concrete road surface
To deformation, overcome the appearance in vertically and horizontally crack.
2, precast prestressed concrete road surface plate arranges retarded adhesive prestressed steel bar, in retarded adhesive prestressed steel bar week
Enclosing slow cohesion agent to become the phase transition process of solid-state from liquid, retarded adhesive prestressed steel bar has been gradually transformed into bonding from soap-free emulsion polymeization,
Make precast prestressed concrete road surface plate from being only gradually transformed at the retarded adhesive prestressed steel of intersection by concentration power at anchor head
Uniformly by Two-way side pressure effect in the diamond-shaped element that muscle surrounds, improve concrete stress, thus effectively extend
The service life of concrete road surface.
3, in the plate of precast prestressed concrete road surface in addition to angularly disposed retarded adhesive prestressed steel bar, remaining only needs
Arrange a small amount of distributing bar in end, road surface and anchorage zone, be greatly saved amount of reinforcement.
4, using assembled oblique bond-retarded prestressed concrete pavement structure, road surface need not arrange transverse joint, can
To solve the infringement phenomenon that produces due to seam of Portland cement concrete pavement, improve Pavement Condition, reduction road rumble,
Increase road-ability.
5, owing to using oblique reinforcing plan, presstressed reinforcing steel length is shorter, can at one end carry out stretch-draw, it is not required that use
Adapter, it is possible to achieve by cement concrete pavement from traditional cast in situs construction, be converted into prefabrication road surface plate, existing
Carry out assembly, it is effectively guaranteed that the construction quality of concrete flag.Meanwhile, watering in concrete construction is eliminated
Build, the operation such as maintenance, significantly shorten the engineering time of cement concrete pavement, simplify work progress.
6, using prefabrication prestressed concrete pavement plate, scene carries out the form of construction work of assembly, fundamentally solves
The problem of Cement Concrete Pavement Maintenance of having determined difficulty, greatly extends the service life of cement concrete pavement.
This utility model is prefabricated in the factory, and transports location and installation to job site, it is not necessary to poured in place concrete, peace
Filling convenient and swift, affected by environment little, concrete pavement slab block is in factory's scale standardized production, and production efficiency is high, matter
Measure, save a large amount of human resources.Road surface need not arrange transverse joint, solves Portland cement concrete pavement due to seam
The infringement phenomenon produced, reduces pavement maintenance and maintenance costs, improves the serviceability on road surface, reduces road rumble, increase row
Car comfortableness, extends the service life of cement concrete pavement.
