Hollow slab bridge with tension connecting piece and construction method thereof
The invention provides a hollow slab bridge with a tension connecting piece and a construction method thereof, prevents a hollow slab bridge hinge joint from cracking under cross bridge direction bending moment effect, and belongs to the bridge engineering field; a horseshoe on the bottom of the hollow slab is provided with a bottomless connecting slot and a hexagon joint; corresponding connecting pieces of adjacent hollow slabs are connected, and can fix each hollow slab in a cross bridge direction and transfer cross bridge direction tension force, thus enhancing hinge seam cross bridge direction bending moment resistant performance of a finished bridge; A hollow slab can be provided with only one type of connecting piece or only a connecting slot on the whole bridge , and two corresponding connecting slots are connected through a bolt after assembling, thus realizing prefabricated standardization. A normal formwork is not changed, bottom plate transverse steel rib or stirrup horizontal segment tension can be used, thus fully utilizing hollow slab base plate steel rib potential; very little work load is added, and needed parts use less consumption material, the hollow slab bridge with the tension connecting piece and the construction method thereof can ensure the bridge from cracking under transverse flexural-tensile stress effect, thus solving hinge joint problems always bothering the hollow slab bridge.
