Low-height channel steel concrete composite beam
The invention relates to the technical field of bridge construction. The utility model relates to a low-height channel steel concrete composite beam. The low-height channel steel concrete composite beam comprises a plurality of groove-shaped beam sections which are spliced with one another, each groove-shaped beam section comprises a bottom plate and a web plate; the upper end face of the bottom plate is in a trapezoid shape with one wide side inclined. Three linear theoretical control points are arranged on the plane where the sections on the two sides of the groove-shaped beam section are located, and the linear theoretical control points comprise the horizontal control point at the intersection point of the longitudinal center line of the upper end face of the bottom plate and the section of the bottom plate and the two elevation control points at the intersection point of the center lines of the upper end faces of the webs on the two sides and the section of the webs. Due to the fact that the upper end face of the bottom plate of each groove-shaped beam section is in the trapezoid shape with one wide side inclined, when a broken line plane is constructed, on the basis that it is guaranteed that the line center line coincides with the bridge center line and the bridge forming line is smooth, connecting parts do not need to be arranged between the adjacent groove-shaped beamsections, the construction process is shortened, and the working efficiency is effectively improved.
本发明涉及桥梁建设技术领域，具体揭示了一种低高度槽型钢混组合梁，包括相互拼接的若干组槽型梁节段，槽型梁节段均包括底板和腹板，底板上端面呈一侧宽边倾斜的梯形，槽型梁节段两侧断面所在的平面上均设置有三个线形理论控制点，线形理论控制点分别包括底板上端面纵向中心线与底板断面交点处的水平控制点，以及两侧的腹板上端面中心线与腹板断面交点处的两个高程控制点；通过设置槽型梁节段的底板上端面呈一侧宽边倾斜的梯形，在建设折线平面时，在保证线路中心线和桥梁中心线重合，成桥线条流畅的基础上，可以免于在相邻槽型梁节段之间设置连接部，缩短了建设流程，有效提高了工作效率。
