Abstract
A profiled steel sheet-UHP (ultra high performance) fiber reinforced concrete composite bridge deck comprises U-shaped profiled steel sheets, perforated steel sheets, vertical studs, horizontal reinforcements, longitudinal reinforcements and UHP fiber reinforced concrete. The vertical perforated steel sheets are longitudinally fixed in the centers of the grooves of the U-shaped profiled steel sheets. A plurality of fixed vertical stud rows are arranged on raised portions of the U-shaped profiled steel sheets. The horizontal reinforcements penetrate connecting holes in the perforated steel sheets and are welded with the upper ends of the vertical studs. The longitudinal reinforcements are perpendicular to the horizontal reinforcements and fixedly connected with joints of the horizontal reinforcements and the vertical studs. The UHP fiber reinforced concrete is poured in the U-shaped profiled steel sheets to cover the perforated steel sheets, the vertical studs and the horizontal and the longitudinal reinforcements. According to the arrangement, the adhesion performance of the interfaces of the profiled steel sheets and the UHP fiber reinforced concrete is improved, and mechanical advantages of the profiled steel sheets and the UHP fiber reinforced concrete are fully played. The profiled steel sheet-UHP fiber reinforced concrete composite bridge deck dead is low in weight, high in bearing capacity, excellent in anti-fatigue performance, available in industrialized production and on-field assemble, higher in bridge deck building and changing speed and the like.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As depicted in figs. 1 and 2, spill profiled sheet 1, open pore steel plate 2, vertical peg 3, transverse reinforcement 5, longitudinal reinforcement 6, very-high performance fibre reinforced concrete 7 is comprised.At spill profiled sheet 1 recess, open pore steel plate 2 is set, convex place arranges vertical peg 3, in open pore steel plate connecting hole 4, run through transverse reinforcement 5 and weld with above vertical peg 3, with transverse reinforcement 5 vertical direction on be provided with longitudinal reinforcement 6, longitudinal reinforcement 6 is positioned at above transverse reinforcement 5, and it is affixed with the tie point of transverse reinforcement 5 and vertical peg 3, very-high performance fibre reinforced concrete is cast in spill profiled sheet 1, and open pore steel plate 2, vertical peg 3, transverse reinforcement 5 and longitudinal reinforcement 6 is all covered.
For the frame type bridge of conventional band longitudinal and cross beam, concrete embodiment is as follows.
The machine-shaping of spill profiled sheet: spill profiled sheet by plain plate in factory's cold moudling, the thick 6-12mm of its light plate, convex place width and recess width are than being 2-4, monolithic profiled sheet width gets the 1-3 of adjacent beams center to center distance in frame type bridge doubly, length is 6-8m, and during blanking, longitudinal cutting position is positioned at the convex surface of matrix steel plate.
Form shear connector.For guaranteeing combining closely between spill profiled sheet and very-high performance fibre reinforced concrete, at the equal two-sided welding of spill profiled sheet groove center one piece of longitudinal open pore steel plate, protuberance welds vertical peg, in open pore steel plate connecting hole, run through transverse reinforcement and weld with above vertical peg, a vertical with it longitudinal reinforcement is all set with vertical peg intersection above transverse reinforcement.Shear connector completes at produce in factory, wherein open pore steel plate thickness is 5-10mm, connecting hole longitudinal pitch is consistent with vertical peg, be 0.2-0.5m, height is higher than the convex surface of spill profiled sheet, lower than the end face of vertical peg, be connected between longitudinal reinforcement with transverse reinforcement by steel wire lashing, longitudinal reinforcement, transverse reinforcement and vertical peg diameter and the vertical peg columns of single convex surface are determined by calculating according to combined bridge deck stressing conditions.
Build very-high performance fibre reinforced concrete.Very-high performance fibre reinforced concrete is a kind of Stainless-steel fibre RPC, and its material fracture toughness reaches 20 ~ 40 kJ/m
2, chloride diffusion coefficient is only (0.02-0.04) × 10
-12m
2/ s.During making, first pour quartz sand, cement, silicon ash, silica flour into forced mixer, dry mixing 5-8 minute; Then pour into disposable for the whole water supply volumes being dissolved with water reducing agent, be stirred to after there is flowing sex character and continue 5-10 minute again; It is even that last mixing of steel fiber continues to be stirred to steel fibre.After completing, very-high performance fibre reinforced concrete open pore steel plate, vertical peg, transverse reinforcement and longitudinal reinforcement are included is built in spill profiled sheet, build the covering curing 24h demoulding, then under 80 ± 5oC high temperature after maintenance 48h, cool to room temperature.All operations of building all complete in factory, and when requiring to build, the four each reserved 10cm in limit are as construction joint, and build rear concrete crushing strength and be not less than 120MPa, tensile strength is not less than 20MPa.
Hoisted in position builds seam.After bridge deck prefabrication completes, larger transport devices such as Beam transportation vehicle is adopted to transport job site to, by erection crane hoisted in position, for ensureing compatibility of deformation between bridge deck and longeron, arrange a neoprene bearing every 6-8m between, its tonnage is determined by the weight of combined bridge deck; First formed overall by the welding of seam crossing spill profiled sheet after having lifted, then by through for open pore steel plate longitudinal measure, for ensureing bridge deck globality, seam crossing transverse reinforcement need be connected through with longitudinal reinforcement; After seam crossing connector is formed, seam crossing spill profiled sheet builds very-high performance fibre reinforced concrete, builds the covering curing 24h demoulding, then under 80 ± 5oC high temperature after maintenance 48h, cool to room temperature, builds until institute's seam the construction carrying out deck paving after maintenance puts in place.
