High-durability maintenance-free prestressed carbon fiber concrete pile
The invention discloses a high-durability maintenance-free prestressed carbon fiber concrete pile which comprises a pile body, a fiber skeleton arranged in the pile body and end plate assemblies fixedly arranged at the two ends of the pile body correspondingly. The pile body is a concrete pipe pile with an annular section; the fiber skeleton comprises GFRP spiral stirrups evenly distributed in the annular direction of the pile body and prestressed CFRP main reinforcements evenly distributed in the annular direction of the GFRP spiral stirrups and fixed to the GFRP spiral stirrups. The end plate assembly comprises an end plate and pile hoops welded to the end plate, and the pile hoops are connected to the two ends of the pile body in a sleeving mode. According to the invention, the prestressed tendons are made of the carbon fiber reinforced composite material, so that the durability is good, and later maintenance is not needed.
本发明公开了一种高耐久免维护预应力碳纤维混凝土桩,包括:桩身、设置于桩身内的纤维骨架及分别固定设置于桩身两端上的端板组件;桩身为环形截面的混凝土管桩;纤维骨架包括沿桩身环向均匀分布的GFRP螺旋箍筋及沿GFRP螺旋箍筋环向均匀分布且固定于GFRP螺旋箍筋上的预应力CFRP主筋;所述端板组件包括端板及焊接于端板上的桩套箍,桩身的两端上均套接有桩套箍。根据本发明,通过利用碳纤维增强复合材料做成的预应力筋,耐久性好、无需后期维护。
