[0033] In certain embodiments, reference Figure 2 As shown, one side of the flange plate 2a is welded to the rod 1a. The first connecting member 3 has two connecting plates 31 and 32. One end face of the first connecting member 3 is welded to the other side of the flange plate 2a, thereby forming a fixed connection between the rod 1a, the flange plate 2a and the first connecting member 3. A plurality of bolt holes 33 are provided on the connecting plates 31 and 32.

[0047] The following is an explanation of the assembly method of the truss node. Figure 8 As shown, the truss node assembly method of the embodiment of the present application includes steps S802 to S808.

[0048] Step S802: docking a first connecting member of one rod member with a second connecting member of another rod member so that a connecting plate of the second connecting member is sandwiched between two connecting plates of the first connecting member.

[0049] Step S804: Connect the first and second connecting members by bolts to form a connection between the two rods.

[0050] Step S806: sleeve the two sleeve elements outside the first and second connecting members connected by bolts, and connect the two sleeve elements by bolts to form a sleeve as a whole.

[0051] Step S808, connecting the two ends of the two sleeve elements to the flange plates of the two rods by means of bolts.

[0052] Among them, one end face of the rod is welded to one side of the flange plate, one end face of the first connecting member is welded to the other side of the flange plate of one rod, and one end face of the second connecting member is welded to the other side of the flange plate of another rod.

[0053] In some embodiments, the rod and the flange plate and the first connecting member or the second connecting member are pre-welded, and the pre-welding can reduce the workload in assembly. It should be understood that the embodiments of the present application are not limited thereto.

At the construction site, bolts 7 are used to connect the second connecting member 4 and the first connecting member 3, the two sleeve elements 5, and the two ends of the sleeve element 5 and the flange plate 2.

[0055] In some embodiments, the semicircular ribs 6 are welded on the sleeve element 5 in the factory, and the size of the semicircular ribs 6 is determined according to the semicircular gap formed between the sleeve element 5 and the first connecting member 3. The lateral area of ​​the semicircular ribs 6 is less than or equal to the lateral area of ​​the above-mentioned gap. The number of semicircular ribs 6 is determined according to the number of bolts 7 connecting the first connecting member 3 and the second connecting member 4. Semicircular ribs 6 are arranged on both sides of each bolt, and there is a certain distance between the bolts 7 and the semicircular ribs 6 to avoid contact. The lateral spacing of the semicircular ribs at the same position on the sleeve element 5 is determined according to the thickness of the first connecting member 3 and the second connecting member 4 after assembly; the vertical spacing of the semicircular ribs 6 on the same sleeve element 5 is the same as the bolt spacing on the second connecting member 4, the semicircular ribs 6 between the bolts 7 are located in the middle of the two bolts 7, and the semicircular ribs 6 on the two sides of the same sleeve element 5 are determined according to the vertical spacing between the semicircular ribs 6.
