Abstract

The invention discloses a concrete composition board unit, a concrete composition board assembly, a bridge body and a splicing construction method. The concrete composition board unit comprises a concrete board, the concrete board is formed on a metal bottom board, a first set of steel bars are pre-buried in the concrete board, a splicing notch is formed in the splicing end of the concrete board, and the splicing notch is arranged to be spliced with a concrete joint section; and the first shearing force connecting piece is arranged on the metal bottom plate and connected with the metal bottom plate, the first shearing force connecting piece is embedded in the concrete plate in advance, part of the first shearing force connecting piece extends out of the splicing end, and the first shearing force connecting piece is arranged to support at least part of reinforcing steel bars in a second group of reinforcing steel bars embedded in the concrete joint section in advance.

Description

technical field [0001] This article relates to concrete composite slab technology, especially to a concrete composite slab unit, component, bridge body, and splicing method. Background technique [0002] Concrete composite slabs are widely used in bridge deck structures, but the existing concrete bridge decks have complicated joint reinforcement arrangements, and it is difficult to make molds. In addition, the steel bars in the joint area need to be connected by welding or mechanical connection, which is inconvenient for construction. [0003] In the application of lightweight and high-strength bridge deck structures, there are few reports on the joint structure of steel-ultra-high-performance concrete (UHPC) composite slabs. For example, steel-ultra-high-performance concrete (UHPC) composite slab has a smaller thickness and lighter weight than the traditional concrete bridge deck. Using it as the bridge deck of a steel-concrete composite structure bridge can further increa...
