A plurality of interlaced bars are located in the hollow layer and inserted into a plurality of first steel trusses and / or a plurality of second steel trusses to connect the first steel trusses and the second steel trusses to form an interlocking composite wall of double steel trusses mesh panels containing a hollow layer. The interlaced bars realize the first The interlocking of the first steel truss and the second steel truss enhances the bearing capacity and flexural resistance during the subsequent on-site integral concrete pouring process.
