Abstract: A modular building wherein the studs and certain other membes are comprised of two half stud members held together by rotating clamps. The half stud members are preferably of identical construction, each including a first longer wall and a second shorter wall, the first and second walls running generally parallel to each other and connected by a bridging section, each wall terminating in a free edge tab portion. The two half stud members are disposed against each other in such a way that the first longer wall of each half stud member is in abutting relationship, such that the respective tabs of the first and second parallel walls extend away from each other, and wherein a vinyl separator is interposed between the abutting first parallel walls. The vinyl separator possesses, at one end, an exterior seal and possesses an interior seal at the other end thereof.

Abstract: Foundation assemblies for buildings comprising sill means and a wall plate connected thereto. The wall plate serves to support a plurality of elongated half-stud members on which vertical wall panels are mounted.In one embodiment of the invention, the sill plate is mounted directly on and connected to a concrete foundation element and comprises a sill plate and a sill locking plate. A flanged stud-tie plate is interposed between the sill locking plate and the wall plate and serves to expedite the mounting of the stud members.In a further embodiment of the invention, the sill means is mounted on a vertically extending pier for supporting the sill plate and associated structure above the ground. In this embodiment, the sill means comprises a sill plate, a sill locking plate and a beam support angle having a portion connected to the pier and the sill plate for supporting the beam of a floor support assembly.
