Prestressed carbon fiber plate anchoring structure for bridge
The invention discloses a prestressed carbon fiber plate anchoring structure for a bridge, and relates to the technical field of bridge reinforcement. A counter-force steel plate is arranged on the tensioning end anchor plate, and a penetrating hole is formed in the counter-force steel plate; the first end and the second end of the carbon fiber plate are each provided with an anchorage device, the anchorage device at the first end of the carbon fiber plate is connected with the fixed end anchor plate, and the anchorage device at the second end of the carbon fiber plate is located on the side, close to the fixed end anchor plate, of the counter-force steel plate; the tensioning tool is used for pulling an anchorage device at the second end of the carbon fiber plate under the action of the counter-force steel plate so as to achieve prestress tensioning on the carbon fiber plate; during use, the fixed end anchor plate and the tensioning end anchor plate are fixed to a bridge to be subjected to prestress tensioning at intervals. According to the prestressed carbon fiber plate tensioning system, prestress can be efficiently applied to a bridge, and compared with an existing common bridge prestress tensioning system, the prestressed carbon fiber plate tensioning system is high in tensioning efficiency and small in prestress loss.
本发明公开了一种桥梁用预应力碳纤维板锚固结构，涉及桥梁加固技术领域，包括：固定端锚板；张拉端锚板，张拉端锚板上设置有反力钢板，反力钢板上具有穿设孔；碳纤维板，碳纤维板的第一端和第二端分别设置有一个锚具，碳纤维板的第一端的锚具与固定端锚板连接，碳纤维板的第二端的锚具位于反力钢板靠近固定端锚板的一侧；张拉工装，张拉工装在反力钢板的作用下，用于牵引碳纤维板的第二端的锚具，以实现对碳纤维板进行预应力张拉；其中，使用时固定端锚板和张拉端锚板间隔固定在待进行预应力张拉的桥梁上。本发明能够高效的为桥梁施加预应力，相比目前常见的桥梁预应力张拉系统，该预应力碳纤维板张拉系统张拉效率高，预应力损失小。
