Example Embodiment
[0030] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following embodiments are specially cited in conjunction with the drawings, and detailed descriptions are made as follows.
[0031] Such as Figure 2~7 As shown, a bridge deck structure composed of prefabricated ultra-high performance concrete slabs and steel bridge decks includes a steel bridge deck 1 and an ultra-high performance concrete slab 2 covering the steel bridge deck. The ultra-high performance concrete slab 2 As a prefabricated component, the prefabricated slab 2-1 is connected to form a monolithic ultra-high performance concrete slab 2 by a reserved cast-in-situ belt 2-2, and then connected with the steel bridge deck 1 through a cement-based adhesive 3 to form a composite deck structure .
[0032] Wherein, the main material cement of the cement-based adhesive 3 can be ordinary Portland cement, sulfoaluminate cement, alkali-activated cement, magnesium ce...
