Fabricated steel-UHPC (Ultra High Performance Concrete) composite structure and construction method
The invention relates to the technical field of bridge assembly, in particular to an assembly type steel-UHPC composite structure and a construction method.The assembly type steel-UHPC composite structure comprises a groove type steel box installed on a top plate and a bottom plate of a side box arch rib to be reinforced, a plurality of sets of supporting sleeves are arranged in the groove type steel box, and a plurality of sets of perforated rib plates are welded in the groove type steel box; chemical bolts are implanted into each set of supporting sleeves, the channel steel box is connected with a concrete arch bridge main arch side box arch rib through the chemical bolts, the channel steel box is matched with the perforated rib plates to form a plurality of sets of concrete pouring cavities, and first UHPC filling layers are poured into the pouring cavities. After being solidified, the first UHPC filling layer is matched with the channel steel box and the chemical bolts to form a reinforcing surface for improving the structural strength on the side edge of the side box arch rib to be reinforced, so that the structural strength is improved.
本发明涉及桥梁装配式技术领域，具体涉及装配式钢‑UHPC组合结构及施工方法，包括安装于待加固边箱拱肋顶板和底板的槽型钢箱，所述槽型钢箱的内部设置有若干组支承套管，所述槽型钢箱的内部焊接有若干组开孔肋板，每组所述支承套管的内部均植入化学螺栓，所述槽型钢箱通过化学螺栓与混凝土拱桥主拱边箱拱肋连接，所述槽型钢箱配合开孔肋板形成若干组混凝土浇筑空腔，浇筑空腔内部浇筑有第一UHPC填充层，第一UHPC填充层固结后配合槽型钢箱和化学螺栓在待加固边箱拱肋侧边形成提高结构强度的加固面，提高结构强度。
