Bridge deck slab joint with UHPC formwork and construction method
The invention discloses a bridge deck slab joint with a UHPC formwork and a construction method.The bridge deck slab joint comprises a prefabricated bridge deck slab and a UHPC joint, the UHPC joint comprises a prefabricated section and a cast-in-place section, the prefabricated section is composed of a bottom plate made of UHPC, the two ends of the prefabricated section are located at the prefabricated bridge deck slab and the cast-in-place section respectively, connecting ribs are arranged in the bottom plate, and the connecting ribs are connected with the prefabricated bridge deck slab and the cast-in-place section. Reinforcing ribs are fixed to the two ends of the connecting rib respectively, the two reinforcing ribs are arranged in the prefabricated bridge deck slab and the cast-in-place sections respectively, reserved ribs are arranged in the prefabricated bridge deck slab and extend into the cast-in-place sections, the two cast-in-place sections form a joint groove, a first fixing rib is arranged between the two reserved ribs, and a second fixing rib is arranged in each cast-in-place section. The second fixing ribs, the connecting ribs, the reserved ribs and the first fixing ribs are fixed through welding or binding, and UHPC is poured in the joint grooves. Compared with the prior art, the reinforcing steel bars arranged in the joint groove are simple in structure and few in working procedure, and the field construction efficiency can be greatly improved. And secondly, the construction cost can be effectively reduced.
本发明公开了一种自带UHPC模板的桥面板接缝及施工方法，该桥面板接缝包括预制桥面板和UHPC接缝，UHPC接缝包括预制段和现浇段，预制段是由UHPC制成的底板构成，预制段的两端分别位于预制桥面板和现浇段处，底板内设有连接筋，连接筋的两端分别固定有加强筋，两个加强筋分别设于预制桥面板内和现浇段内，预制桥面板内设有预留筋，预留筋延伸至现浇段内，两个现浇段构成接缝槽，两个预留筋之间设有第一固定筋，现浇段内设有第二固定筋，第二固定筋、连接筋、预留筋和第一固定筋通过焊接或绑扎固定，接缝槽内浇筑有UHPC。与现有技术相比，本发明在接缝槽内布置的钢筋结构简单，工序少，能够极大地提高现场施工效率。其次，能够有效降低建造费用。
