Definitions

• the present invention relates to prefabricated building components, and, more particularly, to a construction system using interlocking panels, the panels including a polymeric insulated core and a steel exoskeleton.
• a system for constructing a structure, such as a wall, by assembling a plurality of interlocking panels together is provided.
• Each of the panels includes a core made of an insulating material, preferably, expanded polystyrene (EPS).
• the panels include stiffeners (studs) on the outer surfaces; each spaced, preferably to national and international code requirements at 24-inches on center (24" OC), to form a rigid exoskeleton.
• the studs are made of galvanized steel. Unlike in conventional wood framing, the studs do not extend from the exterior surface to the interior surface. Instead, the studs are each structured as C-shaped supports wherein each stud is inserted into a grove pair cut into the core. Accordingly, conduction across the studs from the exterior to the interior, and vice versa, does not occur because the studs do not extend through the panels.
• each of the panels has a top track and a bottom track, these tracks made from steel.
• the bottom panels are attachable to a floor, such as a concrete floor, using suitable fasteners.
• the top tracks are attachable to a ceiling using suitable fasteners.
• the panels can be joined together by fitting complementary L-shaped edges together.
• any suitable mating or attachment method can be used to join adjacent panels.
• workers can build a wall, for example by connecting a series of panels together, and fastening the bottom and top tracks.
• Panels can be assembled to form a corner by trimming a portion of a first track to allow a second track to overlap.
• the corner portion is secured to the floor with an additional fastener for extra strength.
• the panels are marked with indicia to assist in assembly of the wall structure and/or identify the maker and/or seller of the wall system.
• each of the panels can have pre-molded (or cut) channels useable to receive utility runs, such as, for example, wires, cables, and plumbing.
• each panel has a vertical channel and two horizontal channels along the entire width of the panel.
• the horizontal channels have a depth greater than the depth of the groove pairs holding the studs, so as to prevent the studs from impeding utility runs through the horizontal channels.
• a splice plate can be used to connect one top track to an adjacent top track.
• the splice plate can be made of any suitably strong and stiff material and secured to the top tracks by known methods, such as, for example, using adhesive bonding or fasteners.
• the dimensions of the splice plate depend on the dimensions of the top track.
• the studs preferably include inwardly extending tabs to assist in securing the studs to the panel.
• Another notable feature of the present invention is that the components used to create each of the panels are made in accordance with ICC and ICBO code requirements.
• Additional components of the present invention include jam sections that can be inserted between the panels to create window openings or entrance ways such as doorways, and trim tracks that can be used to trim window areas.

• the panel 1 includes a plurality of supports, referred to herein as studs 2, which are made from a rigid material, such as, for example, galvanized steel.
• the panel 1 preferably includes a bottom track 3 and a top track 4, as shown.
• the bottom track 3 can be constructed of a C-shaped, sheet metal having leg members 5, 6 extending upward from a base member 7.
• the top track 4 is identical to the bottom track 3.
• the bottom track 3 can be constructed from 16-gauge galvanized steel sheet metal

• fasteners e.g., expansion bolts, concrete nails, etc.
• the track 3 is secured to a concrete floor using bolts, each bolt secured to the floor using a nut/ washer combination. It is understood that the systems and methods of the present disclosure can be used to create other structures such as roofs. In certain cases, fastening of the bottom track 3 to a floor would then not be necessary.
• FIG. 4 shows the panel 1 in greater detail, according to a preferred embodiment.
• the panel 1 preferably includes a polymer foam insulating core A.
• the insulating core A includes an expanded polystyrene (EPS). Fiber reinforcement, such as, for example, carbon fiber, can be added to the polystyrene for added structural strength.
• the core A can include flame retardant components.
• the insulating core A can be molded in a variety of shapes and sizes and cut to a desired size, by a saw or hot-wire cutting or pre-molded to the desired specifications, for example.
• the insulating core A can be pre-molded EPS and can have a height of about 10 feet, a width of about 4 feet, and a thickness of about 6 inches. (See FIG. 16).
• the density of the EPS used for the insulating core A can be 1.5 pounds per cubic foot, for example.
• a notable and distinguishing feature of the present invention is that the components used to create each of the panels are made in accordance with International Code Council (ICC) and ICBO code requirements.
• ICC International Code Council
• the panel 1 can have two spaced apart parallel groove pairs 8, 9 and 10, 11 of a front side 12 along the entire height of the panel 1, each one of the grove pairs 8, 9 and 10, 11 for receiving a respective stud 2.
• a rear side 13 can also include two groove pairs 14, 15 and 16, 17, each one of the grove pairs 14, 15 and 16, 17 for receiving a respective stud 2, as shown.
• the panel 1 can include more or fewer of the studs 2.
• a single channel can be used instead of the groove pairs to receive the studs 2.
• the groove pairs 8, 9 and 10, 11 are preferably positioned directly opposite of the respective grooves pairs 14, 15 and 16, 17.
• FIGs.. 7 and 17 also shows that core A can be marked with indicia 19 to assist in assembly of the wall structure and/or identify the maker and/or seller of the wall system.
• groove pairs are positioned on the panel 1 so that the studs 2 are spaced about 24 inches apart from each other.
• insulating material is placed between studs which extend the depth of the wall. This permits conduction from one side (interior or exterior) to the opposite side (interior or exterior) of the wall.
• wall structures created with the wall system of the present invention do not allow conduction of heat (and transmission of sound, vibration, etc.) through the studs since the studs do not extend from one side to the opposite side.
• having the studs 2 on both sides 12, 13, without contacting each other prevents conduction from the one side 12 to the other side 13 through the studs 2.
• Panel 1 does not have any conductive components passing through the core A from one side 12 to the other side 13 which results in superior insulative properties.
• One of the front rear sides 12, 13, depending on which will face the interior of the structure to be constructed, can have one or more horizontal channels 20, 22 and/or vertical channels 24 to receive utility runs, such as, for example, electric and plumbing.
• panel 1 has one vertical channel 24 along the interior height of panel 1 and two horizontal channels 20, 22 along the entire width of the panel 1.
• the channel 20 can be spaced eighteen inches from top end 26, and channel 22 can be spaced eighteen inches from bottom end 28.
• the channels 20, 22, 24 can have a square cross-sectional shape, and, specifically, can be a 2.5 by 2.5 inch channel.
• the horizontal channels 20, 22 preferably are made to have a depth into the panel 1 greater than the depth of the groove pairs 8, 9 and 10, 11 extending into the panel 1 to prevent the studs 2 from impeding utility runs through the horizontal channels 20, 22.
• the horizontal and vertical channels 20, 22, 24 and the groove pairs 8, 9, 10, 11, 14, 15, 16, 17 can be pre- molded with the molding of the core A or cut into the core A after formation of the core A.
