Bridge deck structure composed of prefabricated UHPC (Ultra High Performance Concrete) slabs and steel bridge deck and construction method thereof
The invention relates to a bridge deck structure composed of prefabricated UHPC (Ultra High Performance Concrete) slabs and a steel bridge deck and a construction method thereof. The bridge deck structure comprises the steel bridge deck and the UHPC slabs covering the steel bridge deck, wherein the UHPC slabs are arranged at intervals, UHPC cast-in-situ belts are arranged between adjacent UHPC slabs, and the bottoms of the UHPC slabs are connected with the steel bridge deck through cement based adhesives so as to form the composite bridge deck structure. Shear connectors can be appropriately arranged in the cast-in-situ belts so as to enhance the connecting effect of the prefabricated slabs and the steel bridge deck. The construction method of the structure comprises the following steps: constructing steel beams and the steel bridge deck; manufacturing and installing the UHPC slabs; constructing the UHPC cast-in-situ belts; and constructing the surface of the bridge deck. The structure is reasonable in stress, high in strength and stiffness, capable of effectively avoiding the generation of steel bridge deck defects, simple, capable of reducing relatively large shrinkage in a cast-in-situ process of UHPC, and easy to realize batch production in factories; and the structure has important practical values and favorable economic benefits.
