Wood-UHPC (Ultra High Performance Concrete) combined box girder and preparation method thereof
The invention discloses a wood-UHPC (Ultra High Performance Concrete) combined box girder. The wood-UHPC combined box girder comprises a UHPC top plate, a laminated wood web, a laminated wood bottom plate, a laminated wood cross beam arranged at the fulcrum position of a girder body, wherein the laminated wood bottom plate, the laminated wood cross beam and the laminated wood web are connected through transverse prestressed reinforcement, and the laminated wood web is connected with the UHPC top plate through a shearing force connecting part. The invention further relates to a preparation method of the combined box girder. According to the wood-UHPC combined box girder and the preparation method thereof, the structural design is reasonable, and the wood-UHPC combined box girder has the advantages of being light in self weight, high in rigidity, capable of being integrally prefabricated, convenient to transport and install, good in hoisting stability and the like; and the problem that the span of a common wood-concrete composite beam is limited due to low rigidity is solved, the requirement for green transformation development of bridge construction in China can be met, and the wood-UHPC combined box girder has a good application prospect in bridge engineering.
本发明专利公开了一种木‑UHPC组合箱梁，包括UHPC顶板、胶合木腹板、胶合木底板及在梁体的支点位置处设置的胶合木横梁，胶合木底板、胶合木横梁与胶合木腹板采用横向预应力钢筋连接，胶合木腹板与UHPC顶板采用剪力连接件连接。本发明还涉及该组合箱梁的制备方法。本发明结构设计合理，具有自重轻、刚度大、可整体预制、运输安装方便、吊装稳定性好等优点，解决了普通木‑混凝土组合梁因刚度小而使跨度受限的难题，符合我国桥梁建设绿色转型发展的需求，在桥梁工程中有较好的应用前景。
