Profile steel, profile steel-UHPC composite plate, bridge deck slab and steel-UHPC composite beam bridge
The invention discloses profile steel which comprises an upper flange plate and a web plate, and the end of the upper flange plate and/or the end of the web plate extend/extends outwards to form an extending section. The invention further discloses profile steel which comprises an upper flange plate, a web plate and a lower flange plate, and the end of at least one of the upper flange plate, the web plate and the lower flange plate extends outwards to be provided with an extending section. The invention further provides a profile steel-UHPC composite plate which comprises a UHPC plate and a plurality of profile steel, wherein the UHPC plate is arranged on the upper flange plate of the profile steel. The invention further provides a bridge deck slab and a steel-UHPC composite beam bridge. The structure of the end of the profile steel is optimized, and the end of the profile steel is provided with the outer extending section, so that when the profile steel-UHPC composite plate obtained through the profile steel is connected through a wet joint, joint force transmission is more reliable, the tensile capacity is high, rigidity is high, various stress working conditions such as pulling,pressing, bending, shearing and twisting can be borne, and the joint can meet the full-section pulling condition.
本发明公开了一种型钢，包括上翼缘板和腹板，所述上翼缘板和/或腹板的端部向外延伸设有延伸段。本发明还公开了一种型钢，包括上翼缘板、腹板和下翼缘板，所述上翼缘板、腹板和下翼缘板中至少一个的端部向外延伸设有延伸段。本发明还提供一种型钢‑UHPC组合板，包括UHPC板和多根上述的型钢，所述UHPC板设于所述型钢的上翼缘板上。本发明还提供一种桥面板和钢‑UHPC组合梁桥。本发明对型钢的端部进行结构优化，使型钢端部具有外延伸段，利用上述型钢得到的型钢‑UHPC组合板在利用湿接缝进行连接时，接缝传力更加可靠，抗拉能力强，刚度大，可以承受拉、压、弯、剪、扭等各种受力工况，接缝可以满足全截面受拉的情况。
