Single-box single-chamber steel box beam and cross beam connected double-box-chamber steel-concrete composite beam and construction method
The invention discloses a single-box single-chamber steel box beam and cross beam connected double-box-chamber steel-concrete composite beam and a construction method, and the construction method comprises the following steps: step 1, mounting a main beam of two framing steel box beams, and supporting the main beam of the two framing steel box beams through a bracket; secondly, a cantilever bracket is adopted for assisting in mounting of a flange plate; thirdly, temporary cross braces are installed, and the distance between the framing steel box girders is adjusted; and fourthly, the temporary cross braces are dismantled, and a cross beam is installed between the two framing steel box girders. The technology that the two framing steel box girders, the flange plates and the cross beams are installed separately is adopted, the cross beams are installed later, and the situation that when the steel box girders and the cross beams are installed synchronously, cross beam internal force and deformation are too large is avoided; the cantilever bracket is adopted for fixing and adjusting the flange plate, the safety and stability of flange plate cantilever installation are ensured, the elevation of the supporting rod is initially adjusted through the adjusting rod, the elevation of the top of the supporting rod is finely adjusted through the adjustable supporting rod, and accurate installation of the flange plate is achieved.
本发明公开了单箱单室钢箱梁横梁连接双箱室钢混组合梁及施工方法，包括如下步骤：步骤一、安装两分幅钢箱梁的主梁，通过支架支撑两分幅钢箱梁的主梁；步骤二、采用悬臂托架辅助安装翼缘板；步骤三、安装临时横撑并调节分幅钢箱梁之间的距离；步骤四、拆除临时横撑，在两分幅钢箱梁间安装横梁。本发明采用两分幅钢箱梁、翼缘板、横梁分开安装技术，横梁后安装，避免了钢箱梁与横梁同步安装时易出现的横梁内力与变形过大的情况；采用悬臂托架进行固定及调节翼缘板，确保了翼缘板悬臂安装的安全稳定性，通过调节杆初调支撑杆的标高，通过可调撑杆精调其顶部标高，实现翼缘板的精确安装。
