Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to a hollow slab connection structure for a bridge. Background Art
[0002] Hollow slab bridges are one of the most commonly used structural forms for small-span bridges of 10 to 20 meters. Most of them are based on simply supported beams and are suitable for factory-based mass production and prefabricated construction. Their cross-sections are composed of multiple hollow slabs with hinged joints between the slabs. After the hollow slabs are erected, the hinged joints are poured together with the cast-in-place concrete layer of the bridge deck. The multiple hollow slabs, hinged joints and cast-in-place bridge deck form a whole that can withstand loads such as vehicles.
[0003] The existing hollow slab connection structure of bridges still has some defects. Most of the connections are not stable enough. Direct connection through concrete pouring is prone to cracking, which poses certain safety hazards. For this reason, we propose a hollow slab connection structure for bridges. Utility Model Content
