Joint connecting structure of profile steel-UHPC composite board
The invention discloses a joint connecting structure of a profile steel-UHPC composite board. The profile steel-UHPC combined board comprises a plurality of profile steels and UHPC plates fixedly connected to the profile steels. The joint connecting structure comprises profile steel-UHPC combined plates which are adjacently arranged in the longitudinal direction of a bridge and transverse joint structures arranged between the profile steel-UHPC combined plates which are adjacently arranged in the longitudinal direction of the bridge. The transverse joint structures comprise transverse cast-in-place UHPC connecting parts located between the adjacent UHPC plates and fixing connecting pieces used for connecting the adjacent profile steel. The joint connecting structure can greatly reduce theself-weight and the manufacturing cost of a bridge deck slab, and has the advantages of being high in rigidity, durable and the like. The profile steel-UHPC composite board and common pavement are expected to become a special pavement scheme for completely replacing a traditional orthotropic steel bridge deck and steel bridge deck in the future and serve as a second bridge deck scheme to be provided for a large-span bridge.
本发明公开了一种型钢‑UHPC组合板的接缝连接构造，所述型钢‑UHPC组合板包括多根型钢和固接于型钢上的UHPC板，所述接缝连接构造包括纵桥向相邻设置的型钢‑UHPC组合板和设于所述纵桥向相邻设置的型钢‑UHPC组合板之间的横向接缝构造，所述横向接缝构造包括位于相邻UHPC板之间的横向现浇UHPC连接部和用于连接相邻型钢的固定连接件。本发明的接缝连接构造能大幅度降低桥面板的自重和造价，并具有刚度大、经久耐用等优势。本发明的型钢‑UHPC组合板+普通铺装有望在未来成为完全替代传统正交异性钢桥面+钢桥面专用铺装方案，作为第二种桥面方案供大跨径桥梁。
