Large-span I-shaped steel reinforced concrete composite beam
The invention relates to a large-span I-shaped steel reinforced concrete composite beam which comprises a steel beam top plate, a web plate, a steel beam bottom plate, shear nails, end supports, bridge body supports and bridge body reinforcing supports, the web plate is connected between the steel beam top plate and the steel beam bottom plate to form an asymmetric I-shaped steel beam structure with the narrow upper portion and the wide lower portion, and the shear nails are fixed to the upper end of the steel beam top plate. The concrete bridge deck slabs are connected into a whole through the shear nails, the end supports are arranged at the ends of the bridge body, the bridge body supports are arranged in the longitudinal direction of the bridge body, and the bridge body reinforcing supports are arranged on the longitudinal bridge body every 5-6 mm. The tensile property of the steel and the compressive property of the concrete are fully exerted, and the shear-resistant connecting piece not only ensures shear slippage resistance, but also can resist lifting force. The asymmetric I-shaped steel beams with narrow tops and wide bottoms are made of steel plates, and the small cross beams are added between the steel main beams, so that the mechanical property and the pressure resistance of the main beams are improved, and the structure is suitable for the steel main beams with large spans and also suitable for curved bridges.
本发明涉及一种大跨径工字型钢混凝土组合梁，包括钢梁顶板、腹板、钢梁底板、剪力钉、端头支撑、桥身支撑、桥身加强支撑，所述腹板连接在钢梁顶板和钢梁底板之间构成上窄下宽的非对称工字钢梁结构，所述剪力钉固定在钢梁顶板的上端，混凝土桥面板通过剪力钉连接成整体，所述端头支撑在桥身的端部，所述桥身支撑沿桥身纵向设置，纵向桥身每隔5‑6mm处设置桥身加强支撑。本发明充分的发挥钢材的抗拉性能和混凝土的抗压性能，抗剪连接件既保证抗剪滑移又能抵抗掀起力的作用。由钢板制作成上窄下宽的非对称工字型钢梁，钢主梁之间加入小横梁，提高主梁的力学性和抗压性，适用于跨度比较大的钢主梁，也可适用于曲线弯桥。
