Abstract

The invention discloses a prefabricated assembled UHPC composite beam and a rapid construction method. The prefabricated assembled UHPC composite beam comprises a UHPC main beam, a bridge floor plateand a grouting material; the UHPC main beam is a main beam prefabricated by UHPC, and the upper surface of the UHPC main beam is provided with a plurality of U-shaped rebars; grooves are formed in theconnecting positions of the lower surface of the bridge floor plate and the UHPC main beam, and the U-shaped rebars are accommodated in the grooves; and the upper surface of the bridge floor plate isprovided with grouting holes and exhaust holes, wherein the grouting holes and the exhaust holes communicate with the grooves; the grooves are filled with the grouting material; and connection of theUHPC main beam and the bridge floor plate is achieved through the grouting materials. The prefabricated assembled UHPC composite beam has the advantages that on-site pouring is reduced, the strengthis high, the durability is high, and economic benefits are good, and can be widely used in the technical field of bridge engineering.

Description

technical field [0001] The invention relates to the technical field of bridge engineering. More specifically, the invention relates to a prefabricated UHPC composite beam and a rapid construction method. Background technique [0002] Traditional concrete prefabricated bridges need to pour a large amount of concrete on site, which has a great impact on the traffic environment; during the use of traditional concrete prefabricated bridges, they will crack due to the influence of environmental factors, which will affect their performance. [0003] The steel-concrete composite bridge has good mechanical performance and low structural weight; the steel girders and bridge decks are manufactured separately in the factory, and the steel girders can be used as a platform to complete the assembly during on-site installation, which is conducive to the assembly construction of the bridge. Although the steel-concrete composite structure can greatly improve the construction level of bridg...
