Embodiment 1
[0044] A sort of Figure 2 ~ Figure 4 The steel-ultra-high-performance concrete composite deck structure containing the shear structure of the present invention is shown, and the composite deck structure includes the steel bridge deck layer 1 below and the ultra-high-performance concrete layer poured on the steel bridge deck layer 1 2. The lower part of the steel bridge deck layer 1 is provided with longitudinal rib webs 8 , and the steel mesh shear structure 3 is welded above the steel bridge deck layer 1 , and the steel mesh shear structure 3 is embedded in the ultra-high performance concrete layer 2 . The steel mesh shear structure 3 is a double-layer superimposed steel bar composite structure. The double-layer superimposed steel bar composite structure includes a longitudinal bar distribution layer welded on the top surface of the steel bridge deck layer 1 and a transverse bar distribution layer welded above the longitudinal bar distribution layer. The longitudinal bar dis...
