Per pass grooved steel plate two ends are provided with troughing plate fixing hole, are fixed on two crest places of steel corrugated sheet by grooved steel plate set bolt, midfeather crest;
Adjacent twice grooved steel plate end public grooved steel plate set bolt.
Be provided with transverse reinforcement between steel corrugated sheet and grooved steel plate, transverse reinforcement is welded with longitudinal reinforcement;
Transverse reinforcement transverse ends is provided with L-type reinforcing bar, and the L shape end hook of L-type reinforcing bar is on longitudinal reinforcement, and the other end is fixed on steel corrugated sheet by L-type reinforcing bar set bolt.
Per pass grooved steel plate is transverse reinforcement together with being provided with between steel corrugated sheet, and the length of transverse reinforcement is between 1 times of wavelength to 2 times of wavelength.
The longitudinal reinforcement that every root transverse reinforcement welds is five, the crest place of one, centre between per pass grooved steel plate and steel corrugated sheet, two of the both sides trough place between per pass grooved steel plate and steel corrugated sheet, two of most two ends are positioned at transverse reinforcement end.
L-type steel-bar arrangement has two, two trough places between per pass grooved steel plate and steel corrugated sheet, the longitudinal reinforcement of its L shape end hook at this two place.
The present invention has the following advantages:
Ruggedized construction of the present invention, practicablely can improve steel corrugated sheet arch bridge to stressed requirement, solve defect and the thin structural instability problem caused of corrugated steel pipe thickness of existing production technology, steel corrugated sheet assembling technique can be applicable to, be connected with steel corrugated sheet and adopt bolt to twist to set firmly and put, structure is simple, cost is low, easy to operate.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be described in detail.
The present invention 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.
