PREFABRICATED BUILDING SYSTEl~I:
The present invention relates to a building structure and more particularly,
relates
to a prefabricated building structure system.
The use of prefabricated building structures for the building of such
structures as
sheds, garages and utility buildings is well known in the art. Generally, such
structures
have been formed of wood and have comprised wall sections whicih are built and
then
later assembled on site. Normally, it is the responsibility of the owner to
prepare the site
which will include providing blocks for a foundation on which the structure is
placed.
A problem with such structures is that during the change in the seasons and
particularly in cold climates, the surface on which the structure is placed
moves and will
accordingly cause movement in the structure. It then becomes necessary to re-
adjust the
structure in order to maintain its level.
A further problem associated with such structures is that due to the provision
of
supporting blocks and the inherent depth of the floor joist, a structure is
raised from the
ground. This causes a problem in that stairs or a ramp must be built to gain
access and a
space below the structure can become attractive to unwanted. animals or the
like.
It is an object of the present invention to provide a prs~fabricated building
structure
which includes an integrated floor section.
According to one embodiment of the present invention, there is provided a
building
system having a base mold with a plurality of side walls, a plurality of
reinforcing
members extending between the side walls, a plurality of side wall sections
having means
for securement to concrete poured in the base section, and a :roof structure.

Having thus generally described the invention, reference will be made to the
accompanying drawings illustrating an embodiment thereof, in which:
Figure 1 is a perspective view of a completed structure according to one
embodiment of the present invention;
Figure 2 is a perspective view of the assembled shell of the prefabricated
building;
Figure 3 is a perspective view of a base module;
Figure 4 is a top plan view thereof;
Figure 5 is an end elevational view of an assembled ;structure; and
Figure C is a side elevational view of a truss structure.
Referring to the drawings in greater detail and by reference characters
thereto,
there is illustrated in Figure 2 an assembled shell for a prefabricated
building structure
system and which structure is generally designated by referE;nce numeral 10.
Structure 10 includes a pair of base modules 12, 12' which are identical and
which
are suitably joined together. Thus, the base may be made up of any number of
suitable
interconnected modules. One such module is shown in Figures 3 and 4. As may be
seen,
a module comprises a mold type of arrangement having sidE; walls 14, 16, 18
and 20.
Each side wall is made of a metallic material having a wall and inwardly
directed top and
lower flanges. A plurality of rebars 22 are placed in a rectangular pattern
and preferably
secured to the walls by appropriate means such a.s spot welding or the like.
The structure, in a conventional manner, includes a plurality of vertical
studs 24
which are spaced apart and connected by means of spacers 'Z6. A roof structure
28 is also
provided.

Roof structure 28, in a preferred embodiment, employs a plurality of trusses
30
as illustrated in Figure 6. Each truss comprises rafters 31 an:d a truss plate
32. Truss
plate 32 is formed in the shape of a IJ and is connected to both sides of
rafters 31 at
connections 34. For securement to the walls, there are provided end connector
plates 36.
As will be best seen in Figure 5, there is provided a screw threaded member 38
for
each vertical stud 24. These members 3 8 are secured in concrete to ensure the
solidity of
the structure.
Once the structure of Figure 2 has been set in place, c~oncre~te is formed
within the
base module 12, 12'. Thus, there is provided a structure which has. a solid
floor and which
will also ensure the solidity of the arranged structure in areas such as may
have high
winds. Since the structure is connected to the concrete floor, it is extremely
solid.
The assembly may be shipped in a prefabricated manner with the walls lying on
top
of the base structure. Thus, there only remains the matter oil erecting the
walls which can
be done extremely rapidly.
An assembled and finished structure is illustrated in Figure 1. In this
respect, many
different types of finishing materials may be used including brick and the
like due to the
concrete floor.
It will be understood that the above described embodiment is for purposes of
illustration only and that changes or modifications may be made thereto
without departing
from the spirit and scope of the invention.
