Description
Technical field
This utility model belongs to the technical field of bridge prefabrication assembly structure, connects knot in particular to the wet seam of precast body
Structure.
Background technology
At present, the process of splicing seam mainly includes stem grafting seam and wet seam two ways.Stem grafting seam is for executing at stem grafting seam
Work is selected no-solvent type epoxy resin cementing agent two pieces of adjacent beam section are bonded to an entirety between sections.Prefabricated block
Between connect main by the shear connector on contact surface with by the precompression of faying face, the effect of epoxy resin is only intended to
Isolation air, to form the protective effect to prestressed cable, uses the stem grafting stitch of epoxy resin to there is the old of organic material
Change problem, affects the fastness between adjacent two pieces of beam section and durability.Wet seam is prestressed concrete beam body precast block,
Free cantilever erection becomes large-span continuous beam, between beam body use cast-in-place concrete beam block be linked to be entirety seam, but work progress
Complicated loaded down with trivial details.
Summary of the invention
The purpose of this utility model seeks to provide the wet seam of precast body that a kind of simple in construction, durability are high to connect knot
Structure.
For achieving the above object, the precast body wet seam attachment structure designed by this utility model, at least include connecting successively
The first precast body connect and the second precast body, the end surfaces of described first precast body is provided with several shear connector grooves, institute
State the second precast body and end face that the first precast body docks mutually is provided with the shear connector convex body corresponding with shear connector groove, described
Some the first drainage troughs being parallel to each other, described second precast body and the first precast body it is additionally provided with on the end face of the first precast body
Some the second drainage troughs being parallel to each other, described first drainage trough and the second drainage trough it is additionally provided with staggered on the end face docked mutually
Arrange.
Further, described first drainage trough runs through the end face of the first precast body, and it is pre-that described first drainage trough runs through first
The end face of body processed, described second drainage trough runs through the end face docked mutually on the second precast body with the first precast body.
Further, described first drainage trough is arranged on the both sides of shear connector groove, and described second drainage trough is arranged on to be cut
The both sides of power key convex body.
Yet further, the cross section of described first drainage trough and the second drainage trough is semicircle, rectangle or square.
Further, described first drainage trough and the second drainage trough are mutually perpendicular to interlaced arrangement.
Compared with prior art, this utility model has the advantage that
One, by the end face in adjacent two precast bodies docking in precast body of the present utility model wet seam attachment structure
On set up the first drainage trough and second drainage trough of interlaced arrangement, it is possible to achieve its faying face is carried out mortar depositing construction, Ke Yiyong
All of gap on cement mortar closure faying face, forms complete airtight protection system, has durability advantage simultaneously.
Its two, this utility model precast body wet seam attachment structure can use epoxy resin to combine with mortar depositing construction, hold concurrently
There are the construction convenience of epoxy resin and the advantage of the durability of wet seam.

Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As it can be seen, the precast body of the present embodiment wet seam attachment structure, including the first precast body 1 being sequentially connected with and
Two precast bodies 2, the end surfaces of the first precast body 1 is provided with several shear connector grooves 3, and the second precast body 2 is prefabricated with first
The end face of body 1 phase docking is provided with the shear connector convex body 4 corresponding with shear connector groove 3, and the end face of the first precast body 1 also sets
There are some the first drainage troughs 5 being parallel to each other, if being additionally provided with on the end face that docks with the first precast body 1 phase of the second precast body 2
The second drainage trough 6 that dry bar is parallel to each other, the first drainage trough 5 and the second drainage trough 6 interlaced arrangement, the first drainage trough 5 and second
Drainage trough 6 is mutually perpendicular to interlaced arrangement.First drainage trough 5 runs through the end face of the first precast body 1, and the second drainage trough 6 runs through second
The end face docked with the first precast body 1 phase on precast body 2.First drainage trough 5 is arranged on the both sides of shear connector groove 3, and second draws
Chute 6 is arranged on the both sides of shear connector convex body 4.The cross section of the first drainage trough 5 and the second drainage trough 6 be semicircle, rectangle or
Person's square.Preferably, the cross section of the first drainage trough 5 and the second drainage trough 6 is semicircle.
The wet of precast body wet seam attachment structure of the present embodiment connects construction method, comprises the steps:
1) width range of the end face surrounding uniform application about 1cm docked with the second precast body 2 phase at the first precast body 1,
The epoxy resin of uniform application thickness 1mm, later by precompression by prefabricated section to spelling and compressing closely connected, now can extrude a little
Epoxy resin colloid；
2) under the sealing process of faying face surrounding epoxy resin colloid, faying face is formed interior to outside air-tightness ring
Border, inside is the connection environment extended in all direction consisted of the first drainage trough 5 and the second drainage trough 6 interlaced arrangement, according to logical
Normal Construction technology of Pouring cement mortar, carries out mortar depositing construction to the gap of faying face, and slurry runs through the first drainage trough 5 and the second drainage trough 6
The channels interleaved formed, can block unnecessary venthole as the case may be before mud jacking；
3) according to the grout situation of slurry outlet, when judging that the closely knit situation of mud jacking determines final pressure by existing Grouting Technology requirement
Carving, mud jacking completes i.e. to accuse assembly and completes, faying face applies pressure compaction again, completes splicing.
Above, detailed description of the invention the most of the present utility model, it is noted that any those of ordinary skill in the art exist
In technical scope disclosed in this utility model, the change that can readily occur in or replacement, all should contain guarantor of the present utility model
Within the scope of protecting.
