Precast-monolithic reinforced concrete bridge spans

摘要

The invention relates to the field of bridge construction, namely the construction of reinforced concrete and composite bridges with precast-monolithic span.; Prefabricated reinforced concrete monolithic span bridge, divided in the cross section on the team and monolithic part comprises ribs, roadway slab and planarization layer.; The novelty of the utility model is that the team portion is in the form of two or more connected to each other in the lateral direction of the span blocks, monolithic part is made of the alignment layer and the hinge region, wherein the blocks of the span are limited laterally lateral vertical walls and comprise recesses for the hinge region and bolted joints. The recesses for the hinge region are in adjacent blocks of the superstructure opposite one another on contact with the side vertical walls and upper surface of the block of the superstructure, wherein the bolt connection of adjacent blocks of the superstructure located in the zone of the recesses.; In addition, a collecting unit superstructure may comprise an external reinforcement, formed as a tray with two horizontal and disposed therebetween a convex upward portion, wherein the tray is provided with anchors, outside the body of concrete. In the area of ​​recesses for the hinge region removable anchor metal can be arranged included in the body of the alignment layer and attached to the block of the span Bolted connection. A more block superstructure may comprise tie between vertical side walls arranged at the level of locking regions.; The technical result - providing division margin of seasonal time of production and assembly of prefabricated elements monolithic construction parts and simplification of manufacturing prefabricated elements in the local environment.
