Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
The utility model relates to a kind of large-span steel corrugated sheet arch bridge reinforcing structure, comprise the steel corrugated sheet 2 be made up of veneer splicing, be vertically arranged with the grooved steel plate 1 of the adjacent layout of multiple tracks above steel corrugated sheet 2, grooved steel plate 1 cross section is in " several " font, and notch is downward.Per pass grooved steel plate 1 two ends are provided with troughing plate fixing hole 8, are fixed on two crest places of steel corrugated sheet 2 by grooved steel plate set bolt 5, midfeather crest.Adjacent twice grooved steel plate 1 end public grooved steel plate set bolt 5.
Be provided with reinforcing bar between steel corrugated sheet 2 and grooved steel plate 1 and built concrete seven.Be provided with transverse reinforcement 9 between steel corrugated sheet 2 and grooved steel plate 1, per pass grooved steel plate 1 is transverse reinforcement 9 together with being provided with between steel corrugated sheet 2, and the length of transverse reinforcement 9 is between 1 times of wavelength to 2 times of wavelength.Transverse reinforcement 9 is welded with longitudinal reinforcement 3, on every root transverse reinforcement 9, the longitudinal reinforcement 3 of welding is five, the crest place of one, centre between per pass grooved steel plate 1 and steel corrugated sheet 2, two of the both sides trough place between per pass grooved steel plate 1 and steel corrugated sheet 2, two of most two ends are positioned at transverse reinforcement 9 end.
Transverse reinforcement 9 transverse ends is provided with L-type reinforcing bar 4, and the L shape end hook of L-type reinforcing bar 4 is on longitudinal reinforcement 3, and the other end is fixed on steel corrugated sheet 2 by L-type reinforcing bar set bolt 6.L-type reinforcing bar 4 is provided with two, two trough places between per pass grooved steel plate 1 and steel corrugated sheet 2, the longitudinal reinforcement 3 of its L shape end hook at this two place.
