Butt joint prefabricated combined beam and construction method
The invention relates to a butt joint prefabricated combined beam and a construction method. The butt joint prefabricated combined beam comprises a steel main beam, and the steel main beam comprises asteel beam bottom plate and a steel beam web fixed to the steel beam bottom plate; a bottom-layer bridge deck slab is included and arranged at the top of the steel beam web, and the bottom-layer bridge deck slab comprises a concrete web and a concrete top plate; the steel beam web is in butt joint with the concrete web through transverse shear nails; and the height of the steel beam web and the height of the concrete web are changed in the longitudinal bridge direction. By adjusting the heights of the steel beam web and the concrete web, a structural stress is more reasonable, and the durability of the combined beam structure is enhanced while the shear resistance and the pulling resistance of the steel-concrete combined beam are enhanced.
本申请涉及一种对接预制结合梁及施工方法，其包括钢主梁，所述钢主梁包括钢梁底板以及固定于钢梁底板上的钢梁腹板；底层桥面板，其设于钢梁腹板的顶部，且底层桥面板包括混凝土腹板和混凝土顶板；所述钢梁腹板与所述混凝土腹板通过横向剪力钉对接；所述钢梁腹板与所述混凝土腹板的高度沿纵桥向变化。本发明通过调整钢梁腹板和混凝土腹板的高度，使结构受力更合理，增强钢混组合梁的抗剪和抗拔能力的同时，加强结合梁结构的耐久性。
