[Abstract] This technology provides a multi-truss system with strong creep resistance, small residual deformation, good elastic recovery, small inter-joint deformation of upper and lower chords, high load-bearing capacity and good stability, good corrosion and fire resistance, convenient construction, and adaptability to complex stress environments. It is composed of two or more ordinary light timber trusses connected by pin connectors. Each ordinary light timber truss has the same structure, and the pin connectors pass through the chords of each ordinary light timber truss. The ordinary light timber truss refers to a timber truss with standard timber as truss members and toothed plate connections at the joints.

[Claim 1] A multi-frame lightweight timber truss, characterized in that: it is composed of two or more ordinary lightweight timber trusses connected by pin connectors, each ordinary lightweight timber truss having the same structure, and the pin connectors passing through the chords of each ordinary lightweight timber truss; the ordinary lightweight timber truss refers to a timber truss with standard timber as truss members and toothed plate connections at the nodes.
