Detachable prefabricated assembly type closed profiled steel-concrete composite beam and construction method thereof
The invention relates to a detachable prefabricated assembly type closed profiled steel-concrete composite beam and a construction method thereof. The detachable prefabricated assembly type closed profiled steel-concrete composite beam comprises a prefabricated steel-concrete composite structure web, a mortise and tenon joint type steel connecting piece inserted into the upper end of the prefabricated steel-concrete composite structure web and a prefabricated bridge deck matched with the mortise and tenon joint type steel connecting piece for use. The tenon-and-mortise type steel connecting piece comprises a flat steel plate, two first vertical steel plates located on the lower portion of the flat steel plate and two second vertical steel plates located on the upper portion of the flat steel plate, the two first vertical steel plates are inserted into the upper end of a web of the prefabricated steel-concrete composite structure, and shear nails are evenly welded to the portion, between the two second vertical steel plates, of the flat steel plate. A plurality of L-shaped limiting grooves are formed in the two second vertical steel plates at equal intervals, overhanging steel bars are arranged on the edge of the prefabricated bridge deck slab in the transverse direction, the ends of the overhanging steel bars are bent to form U-shaped overhanging steel bars used in cooperation with the shear nails and the L-shaped limiting grooves, the composite beam is detachable, components can be replaced, and the construction period is shortened.
本发明涉及一种可拆卸预制装配式闭口压型钢‑混组合梁及其施工方法，包括预制钢‑混组合结构腹板、承插在预制钢‑混组合结构腹板上端的榫卯型钢连接件以及与榫卯型钢连接件配合使用的预制桥面板，榫卯型钢连接件包括平钢板、位于平钢板下部的两块第一竖向钢板以及位于平钢板上部的两块第二竖向钢板，两块第一竖向钢板承插在预制钢‑混组合结构腹板上端，两块第二竖向钢板之间的平钢板上均匀焊接有剪力钉，两块第二竖向钢板上开设有多个等距离的L形限位槽，预制桥面板边缘处沿横向设置有外伸钢筋，外伸钢筋端部折弯，形成与剪力钉、L形限位槽相配合使用的U形外伸钢筋，组合梁可拆卸，构件可更换，缩短工期。
