Method and arrangement for constructing and interconnecting prefabricated building modules

Abstract

A modular building system allows for quickly and easily erecting prefabricated wall panels on a building foundation at a construction site. The system allows for manufacturing and installing, at a high level, complete budding components, using steps that are highly repeatable and scalable, resulting in construction that is quick and efficient, and easily performed at many types and locations of construction sites. A system in accordance with the invention comprises a wall panel, a floor panel and a roof panel. The wad panel comprises a horizontal member supported along a bottom horizontal edge, and a plurality of vertical studs integral to the horizontal member and extending vertically downward from the horizontal member. A floor panel comprises a rail disposed rigidly fixed to the foundation and defining an enclosure to receive the plurality of vertical studs of the wall panel to thereby vertically position the wall panel upon the foundation.

         11 . A prefabricated wall panel comprising:
 a plurality of sheets disposed adjacently and comprising at least one of:
 a gypsum board, 
 a mineral wool disposed between the metal studs, 
 a sheathing board comprising a first cement board, 
 an insulation layer, and 
 an external cladding layer comprising a second cement board; 
   a horizontal member supported along a bottom horizontal edge formed by adjacent disposition each of said sheets, and   a plurality of vertical studs integral to the horizontal member and extending vertically downward from the horizontal member.   
     
     
         12 . The prefabricated wall panel of  claim 11 , wherein the wall panel further comprises one or more connectors for coupling with the other wall panel, said connectors comprising at least one of:
 a first vertical stud supported along a first vertical edge, and   a second vertical stud supported along a second vertical edge opposite the first vertical edge.   
     
     
         13 . The prefabricated wall panel of  claim 12 , wherein the first and second vertical studs comprise a pair of male and female connectors to couple the wall panel with the other wall panel, and wherein the first vertical stud of the wall panel couples with the second vertical stud of the other wall panel through a screw fastener.
