Embodiment Construction
[0023] Below in conjunction with specific embodiment and accompanying drawing, the present invention will be further described:
[0024] Such as figure 1 As shown, a steel pipe intersecting node reinforced with carbon fiber composite reinforced materials, including a node steel pipe main pipe 1, a node steel pipe branch pipe 2, a cementing agent 3 and a carbon fiber cloth 4, and the node steel pipe main pipe 1 and the node steel pipe branch pipe 2 are circular or rectangular steel pipes; the intersecting joints of the steel pipes are evenly coated with cement 3, and carbon fiber cloth 4 is pasted and wound on the cement 3, and the carbon fiber cloth 4 wraps the intersecting joints of the steel pipes coated with cement 3.
[0025] The way that the carbon fiber cloth 4 surrounds the intersecting joints of the steel pipes is the whole circumference. The number of layers of the carbon fiber cloth 4 is 1-3 layers. The sticking direction of the carbon fiber cloth 4 is axial and / or...
