Longitudinal bridge direction joint connecting structure of profile steel UHPC composite board
The invention discloses a longitudinal bridge direction joint connecting structure of a profile steel UHPC composite plate, a steel beam is arranged below the profile steel UHPC composite plate, a longitudinal stiffening plate is arranged at the transverse end part of the profile steel UHPC composite plate, a bearing platform plate is arranged on a side web plate of the steel beam, the longitudinal bridge direction joint connecting structure comprises cast-in-place connecting parts and reinforcing connecting pieces, wherein the cast-in-place connecting parts are arranged among the profile steel UHPC composite plates, the side webs and the bearing platform plates, and the reinforcing connecting pieces extend into the cast-in-place connecting parts. The reinforcing connecting pieces comprisetransverse shearing force connecting pieces arranged on the longitudinal stiffening plates and the side webs and vertical shearing force connecting pieces arranged on the bearing platform plate. Theinvention further provides a longitudinal-bridge-direction joint connecting structure located between the adjacent profile steel UHPC composite boards. The longitudinal-bridge-direction joint connecting structure has the advantages of being light in dead weight, high in tensile capacity and the like, and a bridge deck of a profile steel UHPC composite board adopting the longitudinal-bridge-direction joint connecting structure is expected to completely replace a traditional orthotropic steel bridge deck in the future.
本发明公开了一种型钢‑UHPC组合板的纵桥向接缝连接构造，所述型钢‑UHPC组合板下方设有钢梁，所述型钢‑UHPC组合板的横向端部设有纵向加劲板，所述钢梁的边腹板上设有承台板，所述纵桥向接缝连接构造包括设于所述型钢‑UHPC组合板、所述边腹板、所述承台板之间的现浇连接部和向所述现浇连接部内延伸的加强连接件；所述加强连接件包括设于所述纵向加劲板、边腹板上的横向剪力连接件和设于所述承台板上的竖直剪力连接件。本发明还提供一种位于相邻型钢‑UHPC组合板的纵桥向接缝连接构造。本发明的纵桥向接缝连接构造具有自重轻、抗拉能力强等优势，采用本发明的纵桥向接缝连接构造的型钢‑UHPC组合板的桥面板有望在未来成为完全替代传统正交异性钢桥面。
