Lida Group has developed an advanced connection system for modular construction that streamlines on-site assembly of its prefabricated building panels into tall residential towers.

Instead of conventional foundation anchoring, the new technology enables stacked installation of self-supporting wall panel modules through an integrated connecting bracket and bolt arrangement.

Prefabricated off-site using zinc-aluminum alloy coated steel, the prefinished load-bearing curtain wall panels feature embedded mounting points based on 3D digital models. Panels precisely interlock at the building perimeter and between floors for rapid erection.

Cranes lift completed floor cassettes which automatically engage into position. Construction workers need only perform minor adjustments and bolt tightening to complete load transfer between panels in a fraction of the time of conventional methods.

By transferring gravity and lateral loads through the intrinsic strength of interlocking components, the system enhances construction efficiency by eliminating the need for temporary scaffolding and form work setup which speeds progress.

Stability is ensured through wedged friction connections that function like mechanical joints. Strategically placed damping and bracing simultaneously provide quake resistance.

The new methodology has received a national patent and cuts schedule by 30-50% compared to typical steel and concrete technologies. This will enable delivery advantages such as shorter development cycles.

Lida aims to commercialize the system through roll-out of demonstration projects exploring integration with BIM, robotic installations, pre-assembly and module delivery. This innovation stands to transform tall building manufacturing worldwide according to industry insiders.
