Description
Technical field
The present invention relates to bridge structure technical field, more particularly to a kind of wet seam construction of floorings.
Background technology
Pre- bridge construction speed, the especially time of exchanging bridge and bridge maintaining have become reduction to traffic and trade
The critical issue of easy Xining.For quickly building, it is prefabricated assembled bridge that one, which has the system of bright prospects,.This
The bridge of type is that the prefabricated of floorings is completed in factory, is transported to construction site and carries out prefabricated bridge by wet seam
Between connection, pass through wet seam between prefabricated bridge and carry out power transmission.
Prefabricated assembled floorings system avoid the holder built of construction site, template erection and concrete pour and
Maintenance, substantially reduces the construction time, improves speed of application.Moreover, because prefabricated bridge be carried out in factory it is prefabricated,
It pours and is easier to be controlled with curing condition, therefore improve the quality and working security of floorings.Due to this prefabricated
Unit construction bridge panel system has the characteristics that the construction time is short, therefore particularly suitable for that can only carry out short-term seasonal construction
Area, harsh climate condition area or the remote districts that poured in place concrete cannot be carried out.
Although prefabricated assembled floorings system have many advantages, such as it is as described above because exist design and construction on
The problem of, the application of this Modular Bridge System is restricted.One is exactly presently used prefabricated bridge floor the problem of being even more important
In terms of there is transmission force property and durability in the wet joint connecting structure between plate.Between presently used prefabricated bridge
Wet joint connecting structure can not effectively prevent the generation and expansion in crack.In addition, the existing frequently-used straight muscle of wet seam crossing is taken
It connects or welding structure, in order to ensure that its intensity must increase wet joint gap, this can increase the use of wet joint grouting concrete
It measures the dosage with reinforcing bar and increases construction cost, the width of wet seam becomes larger but also speed of application slows down.Therefore, there is an urgent need for inventions
A kind of new wet joint connecting structure of prefabricated assembled concrete floorings solves these problems.
Invention content
The object of the present invention is to provide a kind of wet seam types of attachment of sectional type floorings, to solve to exist in the prior art
The problem of.
To realize the present invention purpose and the technical solution adopted is that such, a kind of wet seam of sectional type floorings connects shape
Formula, including polylith are erected at the precast concrete floorings on longeron.
A cuboid is got rid of in the closely wet seam side of the precast concrete floorings, forms tooth socket.Adjacent two pieces prefabricated
Between concrete slab interval formed along bridge to the wet seam of step.
The closely wet seam side of the precast concrete floorings is provided with the upper layer extended on the outside of precast concrete floorings
Embedded bar and lower layer's embedded bar.The upper layer embedded bar and lower layer's embedded bar include along bridge to spaced
Several.The end of the upper layer embedded bar sponson bends out single annular structure I.Lower layer's embedded bar over-hang part
The end divided bends out single annular structure II.The single annular structure I and single annular structure II it is interlaced formed along bridge to
Thimble structure.The upper layer embedded bar sponson of adjacent two pieces of precast concrete floorings corresponds overlap joint or welding.
Lower layer's embedded bar sponson of adjacent two pieces of precast concrete floorings corresponds overlap joint or welding.The handing-over lantern ring
Several major part reinforcing bars are disposed in structure.
Cast-in-place wet joint concrete in the wet seam.Adjacent two pieces of precast concrete floorings pass through neighbouring wet seam
Concrete is connected.The top surface of wet joint concrete is concordant with the upper surface of precast concrete floorings.
Further, the wet joint concrete uses superpower toughness fiber concrete ECC.
Further, when pouring wet joint concrete, drawknot is carried out to wet joint template using tension rib.
Further, described to pour wet joint concrete using flat vibrator vibration compacting.
The solution have the advantages that unquestionable：
1) concrete in thimble structure forms " joinery and its construction ", improves the ability of wet seam Transfer of Shear and moment of flexure,
The generation and expansion in wet seam crossing crack can be effectively prevented.
2) it is substantially reduced wet joint gap, the dosage of wet joint grouting concrete reduces, and speed of application is accelerated, and has more
Economy；
3) the wet seam construction of step makes wet seam tensile region length increase so that wet seam concrete in tension zone is not easy
Cracking；
4) concrete of wet seam is poured using superpower toughness fiber concrete ECC, can effectively prevent wet seam from splitting
The generation and development of seam；
5) it solves the problems, such as single slab bearing, floorings is made to form an entirety.

Specific implementation mode
With reference to embodiment, the invention will be further described, but should not be construed the above-mentioned subject area of the present invention only
It is limited to following embodiments.Without departing from the idea case in the present invention described above, according to ordinary skill knowledge and used
With means, various replacements and change are made, should all include within the scope of the present invention.
Embodiment 1：
The present embodiment discloses a kind of wet seam type of attachment of sectional type floorings, including polylith be erected at it is prefabricated on longeron
Concrete slab 1.
Referring to Fig. 1,2 and 3, a cuboid is got rid of in the nearly wet seam side of the precast concrete floorings 1, forms tooth socket
101.Between adjacent two pieces of precast concrete floorings 1 interval formed along bridge to the wet seam of step 3.
The nearly wet seam side of the precast concrete floorings 1, which is provided with, extends to the upper of 1 outside of precast concrete floorings
Layer embedded bar 2 and lower layer's embedded bar 6.The upper layer embedded bar 2 and lower layer's embedded bar 6 include along bridge to interval
More be arranged.The end of 2 sponson of upper layer embedded bar bends out single annular structure I 201.Lower layer's pre-buried steel
The end of 6 sponson of muscle bends out single annular structure II 601.II 601 phase of the single annular structure I 201 and single annular structure
Mutually be staggered to form along bridge to thimble structure.2 sponson of upper layer embedded bar of adjacent two pieces of precast concrete floorings 1
Correspond overlap joint or welding.6 sponson of the lower layer's embedded bar one-to-one correspondence of adjacent two pieces of precast concrete floorings 1 is taken
It connects or welds.It is disposed with major part reinforcing bar 5 in the handing-over thimble structure.
Cast-in-place wet joint concrete 4 in the wet seam 3.Adjacent two pieces of precast concrete floorings 1 pass through neighbouring wet
Joint concrete 4 is connected.The top surface of wet joint concrete 4 is concordant with the upper surface of precast concrete floorings 1.Corresponding single annular
Structure I 201 and single annular structure II 601 pass through core concrete by core concrete column auto-lock anchorage between lap segment reinforcing bar
The cohesive action of column shearing resistance rather than reinforcing bar and concrete balance overlap joint reinforcing bar pulling force.
In the present embodiment, the wet joint concrete 4 uses superpower toughness fiber concrete ECC.Pour wet seam coagulation
When soil 4, in order to increase the rigidity of wet joint template, drawknot is carried out to wet joint template using tension rib, to prevent wet seam mould
There is the mould phenomenon that rises in plate.The wet joint concrete 4 that pours uses flat vibrator vibration compacting.
