Description

Technical Field

[0001] The utility model relates to the technical field of tube trusses, and more specifically to a tube truss connection node. Background Art

[0002] A tube truss is a lattice structure made of round rods connected to each other at the ends. The trusses make the truss structure economical in material and light in weight. It is easy to form various shapes to suit different uses. For example, it can be made into a simply supported truss, arch, frame and tower, etc. A connection node structure is required to connect two trusses.

[0003] After searching, the utility model patent with the announcement number CN208618553U discloses an assembled tube truss connection sleeve node structure, including a chord, a connection sleeve and a truss connector. The utility model also relates to an installation method of an assembled tube truss connection sleeve node structure, and the installation method includes three steps, three steps and five steps in sequence; the assembled tube truss connection sleeve node structure can set the connection sleeve as a first connector and a second connector; the connection sleeve can also be set as a fixed sleeve, and a filling plate is provided inside the fixed sleeve to prevent the chord and the truss connector from rigidly contacting; the connection sleeve can also be set as a third connector and a fourth connector, and a cross positioning groove is provided on the chord and the truss connector, and the positioning block and the cross positioning groove cooperate to strengthen the connection strength of the node structure.

[0004] However, the above patents still have the following shortcomings: the installation operation is relatively complicated, and multiple screws need to be screwed for installation. The trusses are not convenient to install at high places. Some tube trusses need to be stressed after being connected. The support strength of the connection only at the connection point of two trusses is poor. For this reason, we propose a tube truss connection node. Utility Model Content
