Upper surface band is fluted, and prefabricated stringer 3 is more, is disposed side by side on crossbeam 2 (lower half portion of crossbeam), equally, use is high-strength
Cement mortar is spent, the top surface absolute altitude of prefabricated stringer 3 is adjusted, makes the designed elevation h0 of the top surface absolute altitude bridge floor of prefabricated stringer,
Groove needs in the same plane；
(5) it is high to bridge floor top mark to pour crossbeam (lower half portion of crossbeam is prefabricated crossbeam, and top half is cast-in-place crossbeam)
H0 makes stringer and crossbeam be linked to be an entirety, increases the globality of bridge (structural sections)；
(6) mat formation floorings, be up to the floorings (there are holes for hoist 4 for prefabricated bridge) of installation strength, pass through lifting
Prefabricated bridge is lifted by crane in hole, is transported with wooden handcart to construction site, and adjust the spacing of floorings, controls in 1cm；
(7) with the gap in high-strength mortar filling connecting structure 5, with flexible material (such as extrusion molding styrofoam, pitch
Flax silk, rubber strip etc.) filling prefabricated bridge between gap 6；
(8) bridge deck works construction is completed.
The method for maintaining of prefabricated bridge floor of mating formation, including following operating procedure：
(1) bridge floor is checked, discovery there are the floorings of badly broken, and bridge floor plate surface forms full-length cracks (fracture width ω
>=0.3mm) or concrete fall off；
(2) position, the specification, quantity of damaged floorings are recorded；
(3) floorings for replacing needs, in the prefabricated bridge floor of prefabricated manufacturer's Prefabrication dimension and quantity
Plate, and specification is marked on floorings；
(4) in precast plant's standard curing prefabricated bridge to design strength, by transport vehicle by the preset bridge of dimension
Panel is transported to scene；
(5) high-strength mortar by connecting structure filling is rejected, and by the prefabricated bridge that hole for hoist lifting is damaged, is realized
With the separation and dismounting of former bridge floor；
(6) eliminating impurities in connecting structure are clean, and the flexible material being attached on prefabricated bridge is rejected and is done
Only；
(7) new prefabricated bridge is mounted on corresponding position, and adjusts the spacing of new floorings and former floorings, control
System is in 1cm；
(8) with the gap in high-strength mortar filling connecting structure, the gap between prefabricated bridge is filled with flexible material；
(9) it repeats the above steps, there is damaged prefabricated bridge successively to replace for other, until all replacement is completed.
Only as described above, only specific embodiments of the present invention, when the model that cannot be limited the present invention with this and implement
It encloses, therefore the displacement of its equivalent assemblies, or according to equivalent changes and modifications made by the invention patent protection scope, should still belong to this hair
The scope that bright claims are covered.
