[0077] Specifically, the second upper chord steel bar 202 b is clamped between the first sub-web steel bar 102 a ′ and the second sub-web steel bar 102 a ″, thereby achieving the connection between the first steel bar truss 102 and the second steel bar truss 202 .

[0078] Multiple interpenetrating bars 301 are located in the hollow layer 302 and inserted into the first steel trusses 102 and / or the second steel trusses 202 to connect the first steel trusses 102 and the second steel trusses 202.

[0080] After forming the double-steel truss mesh interlocking composite wall with the hollow layer 302, the concrete layer can be directly filled in the hollow layer 302; or the double-steel truss mesh interlocking composite wall with the hollow layer 302 formed at this time can be used as the smallest wall unit and spliced ​​along the first direction (X axis) or the second direction (Y axis) to form a double-steel truss mesh interlocking composite wall with the hollow layer 302 of the required size.

[0081] In this embodiment, the inserted rib 301 can be made of metal material or non-metal material, as long as it has sufficient strength.

[0082] In this embodiment, the number of the through ribs 301 can be selected according to actual needs without a specific number limit. The maximum number of the through ribs 301 is to fill the first gap 102d or the second gap 102e along the first direction (X axis).

[0084] At the same time, in this embodiment, the first bottom template 100 with the first steel truss 102 and the second bottom template 200 with the second steel truss 202 are formed separately, with the aim of realizing automated assembly line production. Various double steel truss mesh interlocking composite walls with hollow layers 302 can be easily combined as needed. The equipment is simple and does not require a large turning table like the traditional one. The effect is 3-5 times that of the currently known equipment, does not require any mold or formwork, and has a wider range of applications.

[0085] It should be noted that when the first steel truss 102 and the second steel truss 202 are the same, that is, the structure of the second steel truss 202 can adopt the structure of the first steel truss 102 (such as Figures 1 to 2 ), so in some embodiments, please refer to Figure 8 The inserted reinforcement 301 passes through the second gap 102e along the first direction (X axis), that is, the inserted reinforcement 301 is sequentially inserted into the first gap 102d of several first reinforcement trusses 102 and the first gap 102d of the second reinforcement trusses 202 to connect the first reinforcement trusses 102 and the second reinforcement trusses 202.
