Description

FIELD OF THE INVENTION

This invention relates to factory prefabricated building systems. More particularly, it refers to a modular building system employing aluminum extrusions connected to steel faced building panels having a sandwiched interlayer of polystyrene foam insulation.

BACKGROUND OF THE INVENTION

Modular building systems have been in use since at least 1931 as shown in U.S. Pat. No. 1,793,188.

U.S. Pat. No. 2,062,160 describes panels of sheet steel used for the frame work of a building. Adjacent panels of the wall are connected ridgally together by the use of interengaging flanges arranged in box formation along the meeting edges of the panels.

U.S. Pat. No. 2,127,111 describes a structure comprising insulating panels grooved at a portion adapted to contact contiguous panels to define channels between them. There are key strips deposed in the channels and locking devices securing contiguous panels together. The joints are sealed together by compression of the insulating material.

U.S. Pat. No. 3,055,461 describes structural extrusions interlocked together to form structural members.

U.S. Pat. No. 3,751,865 describes a modular building construction fabricated from individual panels. The individual panels consist of frames of extruded metals such as aluminum which by means of snap in moldings support the panels.

U.S. Pat. No. 4,019,291 describes interior wall systems. Each wall frame section includes at least one pair of spaced vertically extended studs and generally horizontal top and bottom stringers for securing the studs in a horizontally spaced position. Each wall frame section includes elongated slots for electrical wires, telephone wires and other utility connection.

U.S. Pat. No. 4,360,553 describes a sandwich type panel that is snap locked together and has a space between each panel. Panels can be assembled together on all sides by a double tongue and groove connection.

U.S. Pat. No. 4,443,986 describes panels employed to divide large rooms into a number of work stations. Each panel support frame has a first and second space upright and first and second gussets including plate support devices secured to the first and second upright. Each of the gussets defines an upwardly opening slot and each slot includes a portion doubled downwardly inwardly with respect to the gusset. A wall panel is mounted within the support frame and a mounting stud extends from the wall panel and is secured within one of the gussets.

U.S. Pat. No. 4,769,963 describes a structural snaplock panel.

U.S. Pat. No. 5,117,602 describes a building including a plurality of structural members connected together forming interconnected walls and floors, each structural member having elongated front panels with lateral ends and side panels extending generally perpendicular from the front panel. Each of the side panels has a generally Z-shaped portion and a first flange at an end of the panel extending toward the other side panel. The adjacent cooperating structural members are nestable with each other at the Z-shaped portions thereof with the flanges of nested side panels cooperating to form a support.

U.S. Pat. No. 5,259,164 describes an improved construction for walls which are constructed of boards and which can be rapidly erected and dismantled and which allow for variable angle adjustments while retaining axis dimension from rotational axis to rotational axis. The coupling element for adjacent wall boards is a hinge, the two sections of which are movable about an axis defining the swiveling axis of the boards and are detachable by a fastening means.

U.S. Pat. No. 5,325,641 describes a system for mounting a panel. There are a pair of studs, each stud having a flange surface which is substantially coplanar with the flange surface of the other stud. A pair of upright members is interposed between the studs and each upright member includes a lip extending generally parallel to a stud flange surface. At least one spring clip is attached to each lip and includes an opening receiving a panel edge.

U.S. Pat. No. 5,966,888 describes a building structure having at least two hollow building elements connected side by side. At opposite sides are coupling members with a coupling member at a first side having a duct. The structure further has a reinforcing beam in the duct member.

Although many of the above described systems have a practical use, there is still a need for a prefabricated building that can be erected with panels that contain insulation and the building is structurally able to withstand 110 mile per hour winds.

SUMMARY OF THE INVENTION

This invention describes a building system that can be pre-fabricated and erected on site with interlocking steel faced panels, the panels containing a sandwiched interlayer of polystyrene foam insulation, attached to multiple aluminum extrusions. The building does not require studs, but can still withstand wind speeds of up to 110 miles, per hour.

The system includes several extrusions. First, a base plate adapter extrusion having a side plate overlapping a side edge of a concrete foundation, a U-shaped component for receipt of a panel, a thermal break and an electrical way with a means for access to the electrical way. Secondly, a roof eve adapter extrusion having a U-shaped component at each end for receipt of opposed roof panels and a means for adjusting the angle of each roof panel with respect to the opposing roof panel. Thirdly, a corner extrusion having a U-shaped component at each end for receipt of panels, with means for adjusting the angle of each wall panel at about 90° with respect to each other. Fourthly, a gable adapter extrusion for the topmost panel having a downwardly U-shaped component for overlapping the top portion of a top panel, together with a base portion on which roof panels are attached. Fifthly, male and female latches interlocking the ends of panels together, but spaced apart sufficiently for receipt of an I-beam between the latches. Lastly, a door or window extrusion having a U-shaped component for receipt of a panel.

DETAILED DESCRIPTION OF THE INVENTION

Throughout the following detailed description, the same reference numerals refer to the same elements in all figures.

The modular building system of this invention is employed to construct a building 10 having insulated side panels 16 and roof panels 18 . The building 10 is constructed over a concrete pad 12 as shown in FIG. 1 . No studs are required to support the panels 16 nor are roof trusses required to support the roof panels 18 .

The building 10 is constructed employing several different extruded aluminum adapters designed to support the insulated panels.

An edge or base plate adapter 14 shown in FIGS. 2 and 2A is mounted over an edge 24 of the pad 12 so that a lower skirt 26 integral with adapter 14 extends downwardly along edge 24 . The adapter 14 has a U-shaped component 15 (a base 38 and sidewalls 23 and 25 ) for receipt of a bottom portion 17 of a panel 16 , and an electrical way 28 distal from the lower skirt 26 . The electrical way 28 has a movable plate 30 which pivots outwardly at a pivot point 32 . Plate 30 engages a projection from sidewall 25 to form a snaplock 31 . A thermal break 34 usually filled with a polymer 36 rests on pad 12 . The base 38 of the U-shaped component 15 is spaced above the pad 12 and is sloped down 40 to a hole 42 to allow moisture to drain out. A threaded rod 44 imbedded in the pad 12 is bolted 46 to the bottom 38 of U-shaped component 15 . A rubber gasket 58 is applied between the interior of the U-shaped component 15 and the bottom portion 17 of panel 16 . A threaded shaft 54 is bolted from bolt head 55 transversely through sidewall 23 , through the lower portion 17 of the panel 16 , sidewall 25 and is held with nut 50 within the electrical way 28 .

The side panel 16 mounted in edge adapter 14 has a steel sheet 52 and 53 on each side sandwiching polystyrene insulation 56 . A groove 60 adjacent an inner side 53 of panel 16 is adapted to receive wall board or other aesthetic panels for mounting on the interior of building 10 .

A second or third wall panel or roof panel can be fastened end to end upwardly using the self mating panel locks 62 shown in FIG. 7 . An interlock component 64 and 66 are each imbedded in the end of a panel and pressed together to create a snaplock 69 . Spaces 63 and 68 are created between the panel ends by the interlock components 64 and 66 . Optionally, an I-beam 70 can be inserted in this space to create additional structural integrity, particularly on buildings over sixteen feet high. A thermal break 65 is located at the end of each panel and screws 67 are used to permanently join adjacent panels.

A wall/roof eve adapter extrusion 71 shown in FIG. 3 has a base plate 72 with a descending outer sidewall 74 and descending inner sidewall 76 enclosing a top portion 77 of an insulated panel 16 . A thermal break 78 is contained within the base plate 72 and a rubber gasket 80 separates the outer and inner sidewalls and thermal break from the insulated panel 16 . An annular groove 82 integral with an outside surface 84 of the base plate 72 receives a ball 86 attached to an L-shaped bracket 88 . The longer portion 94 of the L-shaped bracket 88 has a descending arcuate leaf 90 that is juxtaposed to a corresponding arcuate leaf 92 upwardly directed from base plate 72 . The longer portion 94 of the L-shaped bracket 88 contains a thermal break 87 and supports a lower side 96 of a roof panel 18 . A bolt 98 , starting at bolt head 99 runs transversely from an upper side 100 of the roof panel, through the insulation, the lower side 96 of the roof panel and the L-shaped bracket 88 . A nut 102 holds the bolt 98 in place. The roof panel 18 and side wall panel 16 can pivot with respect to each other at pivot ball 86 until the correct alignment of roof pitch is achieved. A space 89 within leaves 90 and 92 can be used as an electrical way. The upper and lower leaf 90 and 92 are held together with screws 108 for a permanent structure. A threaded bolt 104 with bolt head 105 passes through outer sidewall 74 , the rubber gasket 80 , the wall panel 16 and the inner sidewall 76 . Nut 106 holds the bolt in place.

A corner connector extrusion 110 shown in FIG. 5 joins the sides of sidewall panels 16 at building corners 112 . A base plate 114 has parallel inner sidewall 116 and outer sidewall 118 that enclose a side portion 120 of a panel 16 . A rubber gasket 119 separates inner surfaces of the side walls and base plate from portion 120 . A bolt 122 terminated by bolt head 123 runs through the outer sidewall 118 , a rubber gasket 119 , the insulated sidewall panel 16 and the inner sidewall 116 is held in place by nut 124 . An annular pivot groove 126 is located on outside surface 128 of base plate 114 . A thermal break 130 is located in each base plate 114 . In addition, an outwardly directed arcuate leaf 132 from surface 128 engages a corresponding leaf 134 located on a pivot bracket 136 . The pivot bracket contains a bar 138 supporting a pivot ball 140 at each end. Each ball 140 engages a pivot groove 126 . The pivot bracket 136 also contains a thermal break 142 located between the bar 138 and the arcuate leaf components 134 . The sidewalls can each be pivoted through pivot grooves 126 until a proper orientation is achieved. Thereafter, screws 144 are placed through leaf 132 and 134 to lock the sidewalls in place.

As seen in FIG. 4 , a roof cap bracket 146 is used to capture the end portion 148 of roof panels 18 at the roof peak 20 . The roof cap bracket 146 has two like component parts 150 and 152 . Each component part 150 and 152 has a base 154 and an outer sidewall 156 and inner sidewall 158 . Each base 154 contains a thermal break 160 and an upwardly directed leaf 162 . Each inner sidewall 158 has a downwardly directed leaf 164 . Each of the leaves 162 and each of the leaves 164 are bolted together to form the roof peak 20 . A bolt 166 and 168 respectively, hold an upper end portion 148 of the mating roof panels 18 within the bracket 146 . Screws 170 and 172 respectively, retain together leaves 162 from each base 154 and leaves 164 from inner sidewalls 158 . A thin metal roof cap 174 overlays bracket 146 .

As seen in FIG. 6 , a gable adapter extrusion 176 connects together a roof panel 18 and side panel 16 . The gable adapter 176 has a base 178 and two sidewalls 180 and 182 that encloses the top portion 184 of a wall panel 16 . A rubber gasket 183 is applied between the wall panel 16 and the base 178 and sidewalls 180 and 182 . The base 178 has a descending thermal break 186 and the base 178 has lateral ears 188 and 190 which are bolted 192 and 194 to the roof panel 18 . Bolt 185 having bolt head 187 on one side and nut 189 on another side holds panel portion 184 in place.

As see n in FIG. 8 , a window or doorway 22 adapter extrusion 196 has a base 198 and sidewalls 200 and 202 . A thermal break 204 is located below base 198 and rubber gasket 206 is placed between the adapter 196 and the panel 16 . A bolt 208 holds the panel 16 in place between sidewalls 200 and 202 .

The panels 16 and 18 are usually 4×8 feet in size and have steel external sheets 52 and 53 enclosing a polystyrene insulation. The adapters are extruded aluminum which are made in accordance with well known procedures in the prior art.

The use of the panels and adapters described will result in the rapid construction of an exterior building shell that is completely insulated and without the need for internal studs.
