Embodiment Construction
[0020] figure 1 It is a structural schematic diagram of the present invention, figure 2 for figure 1 right view of the image 3 for figure 1 The enlarged view at A in the middle is shown in the figure: the concrete hollow slab bridge reinforced with transverse steel girders in this embodiment includes a bridge deck beam 1 formed by a plurality of hollow slab girders 2 arranged side by side and a bridge deck beam 1 arranged on the bridge deck. At least one stiffening beam 3 on the bottom surface of the beam 1 is used to laterally reinforce it so that the load on each hollow slab girder 2 can be transmitted laterally. For hollow slab bridges, it is enough to install one stiffening beam 3 in the middle of the span. For hollow bridges with serious hinge joint disease, three or more stiffening beams 3 can be installed according to the overall stress requirements, which can improve the bearing capacity of the bridge and avoid single-slab stress and prolong the service life of t...
