Composite reinforced type steel sleeve joint for assembling FRP pipe truss and mounting method of composite reinforced type steel sleeve joint
The invention relates to a composite reinforced steel sleeve node for FRP (fiber reinforced plastic) pipe truss assembly and an installation method, the composite reinforced steel sleeve node comprises an FRP pipe, an inner threaded steel sleeve and at least two hollow bolts, the FRP pipe is at least partially sleeved in the inner threaded steel sleeve; the hollow bolt penetrates through the FRP pipe in the hollow bolt from the surface of one side of the internal thread steel sleeve and penetrates out of the surface of the other side of the internal thread steel sleeve, ultra-high performance concrete is filled between the FRP pipe and the internal thread steel sleeve and inside the FRP pipe, a notch is formed in the middle of the hollow bolt, an opening is formed in one end face of the hollow bolt, the opening is communicated with the notch, and the opening is communicated with the FRP pipe. And two ports, in the axial direction of the hollow bolt, of the notch are positioned in a gap between the FRP pipe and the internal thread steel sleeve. The fiber reinforced composite material which is good in chemical corrosion resistance and insulating property, simple in forming process, light in weight, high in strength, good in anti-seismic property, high in construction speed and high in industrialization degree is introduced, and UHPC is injected, so that the node anchoring capacity is improved.
本发明涉及一种FRP管材桁架拼装用复合增强型钢套管节点及安装方法，包括FRP管材、内螺纹钢套管、至少两个中空螺栓，FRP管材至少部分套设于内螺纹钢套管内，中空螺栓自内螺纹钢套管的一侧表面穿过其内的FRP管材并从内螺纹钢套管的另一侧表面穿出，FRP管材、内螺纹钢套管之间以及FRP管材内部填充有超高性能混凝土，中空螺栓的中部开设有槽口，中空螺栓的一个端面具有开口，开口与槽口连通，槽口在中空螺栓轴向方向的两个端口位于FRP管材与内螺纹钢套管之间的间隙处。本发明引入具有耐化学腐蚀性好、绝缘性能好、成型工艺简单，重量轻、强度高、抗震性能好、施工速度快、工业化程度高的纤维增强复合材料，并注入UHPC，以提高节点锚固能力。
