3 Claims. (Cl. 20-4)
This invention relates to a portable building, and more
particularly to a building having detachable walls, ?oor
and roof which may be formed into a compact assem
adapted to be detachably assembled to permit the build
mg to be erected as shown in FIGURE 1, and which
may be detached and formed into a compact assemblage,
as illustrated in FIGURE 2, for the purpose of trans
portation.
The ?oor or base structure 10 is preferably of rectan
gular shape supported‘on spaced apart parallel beams,
blage for transportation, and to means for detachably 10 such as the I-beams 18, which may form skids by which
