Finally, the bamboo jump plate 90 is installed on the side of the third cross brace 30 and the second cross brace 20 away from the first cross brace 10, so that the two connecting protrusions 91 of the bamboo jump plate 90 are respectively matched with the fixing protrusions 60 of the third cross brace 30 and the second cross brace 20, and the connection between the bamboo jump plate 90 and the third cross brace 30 and the second cross brace 20 is reinforced by the connecting piece 92 to prevent the bamboo jump plate 90 from collapsing due to wind or accidental touch.

[0034] When the steel pipe 70 is installed, the fixing protrusion 60 on the surface of the steel pipe 70 of the inclined brace 40 can be clamped into the connecting groove 50 of the first cross brace 10 and the third cross brace 30, and the fixing protrusions 60 at both ends of the inclined brace 40 can be respectively abutted with the first clamping end 71 above the third cross brace 30 and the first clamping end 71 below the first cross brace 10. At this time, the inclined brace 40 will be fixed outside the first cross brace 10 and the third cross brace 30 due to the limiting of the fixing protrusion 60 by the first clamping end 71, avoiding the inclined brace 40 from falling off, and the fixing protrusion 60 and the second clamping end 72 can be fixedly connected by screws to further enhance the stability of the oblique steel pipe 70.

[0035] It can be understood that the number of steel pipes 70 of the first cross brace 10, the second cross brace 20, the third cross brace 30 and the inclined brace 40 is not limited to the embodiment, and the number of steel pipes 70 can be selected according to the needs of the site.
