Modular buildings are connected primarily through bolting the modules together and then sealing the joints for weather-proofing. This process occurs after the modules are positioned on the foundation.
Here's a more detailed breakdown:
-
Placement: Modules are transported to the site and then carefully lifted by crane or rolled onto the prepared foundation.
-
Bolting: The modules are precisely aligned and then bolted together. This creates the structural connection between the individual units. This often involves bolting through pre-engineered connection points.
-
Sealing: After bolting, the joints between the modules are meticulously sealed to ensure weather-tightness and prevent water damage. This sealing process often includes specialized sealants and flashing.
-
Utility Connections: Once the modules are structurally connected, utilities like electricity, plumbing, and HVAC systems are connected to create a fully functional building.
-
Finishing: Exterior siding and roofing are completed to give the modular building a cohesive and aesthetically pleasing finish, effectively hiding the module connections.
Therefore, modular buildings are fundamentally connected through a combination of structural bolting and weather-tight sealing, followed by integration of utilities and finishing details.
