[0037] Such as figure 1 As shown, the prefabricated composite corrugated steel web T-beam bridge of the present invention includes a reinforced concrete top slab 1 and a longitudinal beam 2 arranged under the reinforced concrete top slab 1. The reinforced concrete top slab 1 is composed of multiple pieces with the same width as the bridge deck The strip plates are spliced together. The splicing surfaces of two adjacent strip plates are provided with matching assembling slots 1.1. The strip plates are provided with insertion holes 1.2 corresponding to the position of the longitudinal beam 2; It is a set of corrugated steel webs 2.3 welded with top edge steel plate 2.1 and bottom edge steel plate 2.2. The top edge steel plate 2.1 is welded with connecting nails 2.4. The connecting nails 2.4 pass through the insertion hole 1.2 and pass through the pouring concrete 3 and the strip. The corrugated steel webs 2.3 are welded with a plurality of transverse steel partitions 4 arranged ...
