Fiber reinforced composite (FRP) winding type truss connecting joint
The invention discloses a fiber reinforced composite (FRP) winding type truss connecting node. The fiber reinforced composite (FRP) winding type truss connecting node comprises an FRP pipe, a prefabricated node component and fiber cloth impregnated with resin. The FRP pipe is pretreated according to the truss node type and the prefabricated node component, the end of the prefabricated node component is inserted into the FRP pipe and spliced with the FRP pipe, and the fiber cloth impregnated with the resin is wound and arranged in a node area formed by preliminarily splicing the FRP pipe and the prefabricated node component in a reasonable winding mode. And after being cured, the fiber cloth can be used as a main load-bearing component of the truss node. The FRP pipe and the prefabricated joint component are connected through the fiber cloth impregnated with the resin, the number of needed parts is small, efficiency is high, construction is convenient, the fatigue problem caused by stress concentration generated by traditional gluing, bolting and mixed connecting methods and the corrosion problem of steel are effectively avoided, and the service life of the FRP pipe and the prefabricated joint component is prolonged. The joint is excellent in bearing performance, high in rigidity, resistant to fatigue and good in durability, and the performance advantages of a composite material in a truss structure can be fully exerted.
本发明公开了一种纤维增强复合材料（FRP）缠绕式桁架连接节点，包括FRP管，预制节点构件和浸渍树脂的纤维布。FRP管依照桁架节点类型和预制节点构件进行预处理，将预制节点构件端部插入FRP管内部并与FRP管拼接，浸渍树脂的纤维布通过合理的缠绕方式缠绕布置于FRP管和预制节点构件初步拼接成的节点区域，待纤维布固化后便可作为桁架节点主要承力构件。本发明利用浸渍树脂的纤维布对FRP管和预制节点构件进行连接，所需零件数量少、效率高，施工方便，有效避免了传统的胶接、栓接及混合连接方法产生的应力集中引起的疲劳问题以及钢材的锈蚀问题，该节点承载性能优异、刚度大、抗疲劳、耐久性好，能够完全发挥复合材料在桁架结构中的性能优势。
