Description

Technical Field

[0001] This utility model relates to a prefabricated tubular truss connection node, belonging to the field of tubular truss installation technology. Background Technology

[0002] A steel pipe truss is a lattice structure composed of round members connected at their ends. The trusses make the truss structure economical in terms of material usage, lightweight, and easy to form into various shapes to suit different applications. Compared to space frame structures, pipe truss structures eliminate the need for lower chord longitudinal members and spherical joints, thus meeting the requirements of various architectural forms.

[0003] Staggered truss steel structures are composed of multiple intersecting trusses, which are typically made of steel, hence the name. The staggered truss layout increases the redundancy of the structure, thus providing better seismic and wind resistance. However, current technology is not comprehensive and has the following drawbacks: When connecting and installing the staggered upper and lower tubular trusses, connection components are required at the connection points to ensure the stability of the steel truss structure. However, existing connection components have insufficient stability.

[0004] To solve one of the above problems, there is an urgent need for a prefabricated tubular truss connection node. Utility Model Content

To this end, a prefabricated tubular truss connection node is provided.

The bottom ends of the left-side hoisting mechanism and the right-side hoisting mechanism are respectively connected to the first upper chord and the second upper chord. A main support beam is connected between the left-side hoisting mechanism and the right-side hoisting mechanism. A middle hoisting mechanism is installed on the main support beam.
