Detailed description of the invention
As shown in Figure 1, the present invention includes the steel web 2 that wooden top board 1-1, wooden base plate 1-2 under wooden top board 1-1 and two are laid in respectively the left and right sides between wooden top board 1-1 and wooden base plate 1-2, wooden top board 1-1 and wooden base plate 1-2 are all level to laying, and two described steel webs 2 are symmetrical laying.All consistent across footpath with constructed case beam of the longitudinal length of described wooden top board 1-1 and wooden base plate 1-2, and the width of the two is all consistent with the direction across bridge width of constructed case beam.In conjunction with Fig. 2 and Fig. 5, described wooden top board 1-1 and wooden base plate 1-2 are superimposed plank 6, described superimposed plank 6 is made up of the polylith strip plank being bolted together side by side, and between strip plank, is fastenedly connected and is integrated by multiple tracks prestressed strand 4 described in polylith.Described in polylith, strip plank is laid on same plane, and polylith strip plank is all vertical bridge to laying.Described in multiple tracks, prestressed strand 4 is all direction across bridge laying.Two described steel webs 2 are corrugated steel.
In the present embodiment, in described superimposed plank 6, described in polylith, transverse width and the thickness of strip plank are all identical.
When actual use, the applicable bridge of the present invention is the bridge in Middle Or Small Span footpath, and Short/Medium Span Bridge be generally 5m～40m across footpath.Thereby in the present embodiment, the longitudinal length of described wooden top board 1-1 and wooden base plate 1-2 is 5m～40m.When practice of construction, described wooden top board 1-1 and wooden base plate 1-2 strip plank used longitudinally length direction is rift grain, and described wooden top board 1-1 and wooden base plate 1-2 are all not less than 184mm.
In the present embodiment, described strip plank is assembled from front to back by polylith rectangle plank sections.Thereby actually add man-hour, only need adjust being assemblied to form longitudinal length and the quantity of rectangle plank sections described in the polylith of described strip plank, just the object can easy realization the longitudinal length of superimposed plank 6 being adjusted accordingly, to meet the different instructions for uses across footpath bridge.
In the present embodiment, before and after in described strip plank between adjacent two described rectangle plank sections with finger, cementing or connect by metal connecting piece, correspondingly, the junction between the adjacent two described rectangle plank sections in front and back forms a banjo fixing butt jointing 7.
When actual processing and fabricating, the banjo fixing butt jointing 7 in described superimposed plank 6 in the adjacent two described strip planks in left and right all should before and after the laying of staggering.In the present embodiment, banjo fixing butt jointing 7 quantity in the adjacent four described strip planks in left and right, same position place are one.
Thereby, described in polylith in described superimposed plank 6, strip plank utilizes described in multiple tracks prestressed strand 4 to add in advance side direction compressive stress to be fastenedly connected, decapacitation is directly born outside wheel load, load can be passed to the bridge deck that are adjacent, thereby not only simple in structure, processing and fabricating facilitates and stressed effect is good.When practice of construction, it is upper or divide up and down many rows to lay that prestressed strand 4 is laid in same row described in multiple tracks, and the upper equal correspondence of described wooden top board 1-1 and wooden base plate 1-2 has the preboring duct of passing for prestressed strand 4.In addition, the superimposed number of plies of described superimposed plank 6 (forming the quantity of strip plank described in the polylith of superimposed plank 6), the width requirement by Practical Project to constructed case beam and determining.
Meanwhile, according to the thickness of superimposed plank 6 and the case beam of constructing across footpath, the row of laid prestressed strand 4 is adjusted accordingly.When the thickness of superimposed plank 6 is larger, the row of the prestressed strand of laying 4 is more; Vice versa.And work as the larger across footpath of the case beam of constructing, the row of the prestressed strand of laying 4 is more; Vice versa.In the present embodiment, prestressed strand 4 is laid on same row described in multiple tracks.When practice of construction, prestressed strand 4 also can divide two rows to lay described in multiple tracks.
Actual when described prestressed strand 4 is constructed, prestressed strand 4 is passed from the preboring duct of superimposed plank 6 interior settings, the anchor ingot plate 3 of the left and right side of the both ends of prestressed strand 4 by being laid in superimposed plank 6 carries out anchoring afterwards.Meanwhile, described prestressed strand 4 needs first through preservative treatment, and its method for anticorrosion treatment is identical with the method for anticorrosion treatment of conventional prestressed reinforcement.
In the present embodiment, in conjunction with Fig. 7, described anchor ingot plate 3 comprises the channel-section steel that is laid in superimposed plank 6 sides, on described channel-section steel, have the hole that passes passing for prestressed strand 4, and prestressed strand 4 from described in pass hole and pass after, be fixed with fastening bolt 9, and between described fastening bolt 9 and described channel-section steel, pad is equipped with rectangle backing plate 8.
