Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing, to the present invention into
Row is further described.
As shown in Figure 1-3, vertical connecting plate girder construction disclosed by the invention, it includes plate body 1, after being reserved with longitudinal direction in plate body 1
Tension prestress duct 15 and lacing hole 13 for installing longitudinal lacing wire between beam slab.Longitudinal post-tensioned prestressing duct 15 it is several
According to needing to be arranged.By wearing prestressing tendon in longitudinal post-tensioned prestressing duct 15, in plate body 1 before by external force, to prestressing force
Beam applies pre-tensile stress, to apply prestressing force in advance in plate body 1, so that plate body 1 bears compression, and then it is made to generate one
Fixed deformation, to improve its bending resistance and rigidity.
In present embodiment, plate body 1 is frame plate, and there is a hollow out 14 in center, and lacing hole 13 is through the hollow out 14 and plate body 1
End face.
When above-mentioned plate body 1 is used for railroad bridge, to avoid Short wave irregularity, 1 top surface of plate body has what is be recessed to be used for
It is embedded in the rail support groove 11 of rail, the longitudinal both ends of the surface for running through plate body 1 of rail support groove 11,11 parallel interval of rail support groove is equipped with two.This
" top surface " in specific embodiment refers to upper surface when plate body 1 is installed and used.Longitudinal post-tensioned prestressing duct 15 has two groups,
Two groups of longitudinal directions post-tensioned prestressing duct 15 is located at the lower section of a wherein rail support groove 11.Two groups of longitudinal directions post-tensioned prestressing duct
15 are symmetrical arranged, and longitudinal post-tensioned prestressing duct 15 shares 6.Certainly, longitudinal post-tensioned prestressing duct 15 may be alternatively provided as 3
Group, 4 groups it is even more, but the lower section of two rail support grooves 11 should respectively have one group.In use, rail to be directly inlaid in rail support groove 11
In, continuous support can be provided rail, the vibration source of the overwhelming majority is consumed, keep train operation smooth, extend rail and train
Service life.1 side of plate body is provided with pre-buried emepalcement casing 3 and the fixed pipe sleeve 5 of third rail bracket.
The both ends of plate body 1 have and limit the matched constraint notch 12 of convex block machine, by that will constrain notch 12 and limit convex
The assembly of type block machine, can limit single plate body 1.
Invention additionally discloses a kind of hardened structures of longitudinal connected track, and as shown in Figure 4,5, it includes multiple rail plate-girders and limit convex
Block machine 6, multiple rail plate-girders are longitudinal, interval is laid with, limit convex block machine 6 in constraint notch 12, two neighboring rail plate-girder by
Longitudinal lacing wire 4 links together between two beam slabs, and longitudinal lacing wire 4 is in lacing hole 13 between beam slab.Constraining notch is U-shaped or half
Circle, two neighboring PCslab girder share the same limit convex block machine 6.Rail 2 is inlaid in rail support groove 11.
The size of plate body 1 is set as needed, the thickness of plate body 1 and its length direct proportionality.In present embodiment
The length of plate body 1 be 4.8m-9.8m, plate body 1 with a thickness of 400~700mm.In addition, present embodiment additionally provide thickness with
The relation table of length, is shown in Table 1.
Table 1

The production method of above-mentioned vertical connecting plate girder construction disclosed by the invention, early period, needs produced and the matched steel of plate body 1
Then model is produced according to the following steps:
Step a binds the reinforcement cage skeleton of plate body 1, is incorporated to punching block；
Step b installs 13 pore-forming pvc pipe of lacing hole between vertical connecting plate joist steel mould end and interior punching block, and fixed；
Interior punching block corresponds to the hollow out 14 of plate body 1.
Corresponding position in longitudinal post-tensioned prestressing duct 15 installs bellows+bushing pipe or other pipelines, bushing pipe or other
Pipeline goes out side and touches.The lower surface when upper surface of plate body 1 during installation is prefabricated has the one of rail support groove 11 face-down.Plate body 1 exists
Inverted camber is set when prefabricated, the pipeline of longitudinal 15 corresponding position of post-tensioned prestressing duct installation sets same inverted camber.Plate body is longitudinal
Post-tensioned prestressing duct 15 has 4-6.Changed according to the length of plate body 1, longitudinal post-tensioned prestressing duct 15 can be increased or decreased
Number.
Step c, casting concrete extract bushing pipe and pvc pipe, and continue steam curing after concrete initial set；
Step d, demoulding, hangs out plate body 1, is verified.The spatial position for taking out bushing pipe and pvc pipe, i.e., in the original of bushing pipe
Longitudinal post-tensioned prestressing duct 15 is formed at beginning position, the home position of pvc pipe forms lacing hole 13, completes the production of plate body 1.
After plate body 1 completes, subsequent progress prestressed stretch-draw and continue to conserve.Specific step is as follows；
Step 1, prestressing tendon is worn in longitudinal post-tensioned prestressing duct 15；
Step 2, using jack tension prestressing tendon, when tensioning, plate body 1 is that reverse side is placed, and has the one of rail support groove 11
Down.After the completion of tensioning, sealing off and covering anchorage is carried out using macromolecule concrete.Make the arch 5mm-10mm in advance of plate body 1 by prestressed stretch-draw.
Step 3, the rail plate-girder after sealing off and covering anchorage hang in water support pond, continue water support and natural curing.
The present invention provides a kind of superstructure of completely new bridge, track function and bridge function is combined into one, not only
It constitutes simply, and construction cost can be reduced.Longitudinal direction post-tensioned prestressing duct is reserved in plate body, by wearing prestressing force in it
Beam applies prestressing force in advance in plate body, so that plate body bears compression, and then it is made to generate certain deformation, when train passes through
Out-of-date, the prestressing tendon inside worn can first resist train impact load.
The lacing hole that longitudinal lacing wire between installing beam slab is reserved in plate body, will be multiple by filling longitudinal lacing wire in lacing hole
Rail plate-girder is joined together to form long section or completely indulges connecting plate beam.When one end stress of rail plate-girder, the other end is by longitudinal direction
Lacing wire is held to bow and be upturned downwards, can enhance the overall stability of track.And the present invention can be to rail
Continuous support is provided, it is smooth conducive to train operation, extend the service life of rail and train.
Certainly, the present invention can also have other numerous embodiments, without departing substantially from the vertical even feelings of thought and its essence of the present invention
Under condition, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these change accordingly
Become and deformation all should fall within the scope of protection of the appended claims of the present invention.
