METHOD AND SYSTEM FOR A MODULAR BUILDING STRUCTURE
A method and system for construction of building structures from a variety of standard size panels having integral dovetail tenons on all four edges and a variety of connectors with corresponding mortises for interlocking the panels. The panels may be horizontally disposed to form floors, ceilings or roofs or may be vertically disposed to form walls. The panels are produced from blow-molded plastic. Panels are interlocked in columns and rows of a planar array to form walls, floors, roofs, etc. Panels can also be interlocked edge to edge in a non-planar orthogonal manner, allowing the panels to be interconnected in virtually unlimited ways. Plastic frame members with trussing interconnect to the panels to provide rigidity and strength to the assembled building structure. The panels may be formed of opaque material for ordinary sheds or of transparent or translucent material for greenhouses.
1. Field of the Invention
This invention relates to building structures generally and to a method of producing a building structure from pre-fabricated modular components. More particularly, this invention provides for assembling a warehouse, aircraft hanger, workshop, garage, storage building, garden or utility shed, greenhouse, cabinet, locker, or similar enclosure from pre-fabricated modular components.
2. Description of the Prior Art
There has long been a need for affordable, low-maintenance, and easy-to-assemble prefabricated building structures. Considerable economies of scale can be achieved by the construction of warehouses, hangers, storage buildings, workshops, garages, garden and utility sheds, lockers and cabinets in modular fashion using prefabricated paneling. The panels can be prefabricated in standard sizes by relatively high-speed automated factory manufacturing lines. The panels, which can be made from materials not subject to rot, weathering or insect attack, can be shipped to the installation sites and simply assembled to erect complete structures. Generally, the lighter the panels are, the lower the costs are to transport the panels to the job site.
For example, several storage enclosure systems exist that use modular interlocking components made of vinyl, plastic, galvanized steel or aluminum to form a structure. For example, U.S. Pat. Nos. 6,591,558 and 6,889,475, issued to De Zen, disclose a prefabricated plastic shed, shown here in
As illustrated in
Greenhouses are also known in prior art. Typically, prior art greenhouses employ individual wall and roof panels each having steel or aluminum frames glazed with shatter-resistant glass or plexiglass. The glass panels are then assembled into a shed-like structure similar to the shed (10) of

SUMMARY OF THE INVENTIONThe objects identified above, as well as other features and advantages of the invention are incorporated in a method for manufacturing building structures including warehouses, aircraft hangers, garages, workshops, storage buildings, sheds, greenhouses, cabinets, lockers, and similar enclosures which preferably includes a variety of standard size panels and connectors for interlocking the panels. The panels may be horizontally oriented to form floors, ceilings, or roofs, or may be vertically oriented to form walls. The panels are preferably made of a blow-molded plastic. Using a connector element, panels may be interlocked, one vertically above the other to form walls in a vertical direction. Likewise, panels can also be interlocked side by side with the connector element to form continuous walls in a horizontal direction. A connector element also allows the interconnection of vertical to horizontal panels. The storage enclosure is preferably supported by plastic frame elements of truss design which are likewise interlocked together to form-frames, joints and beams. Plastic shelving support arms preferably interlocked directly to the frame elements. The panels may be made of a transparent or translucent plastic material for providing sunroofs, windows, or for constructing greenhouse structures.
The invention is described in detail below by reference to the embodiments illustrated in the accompanying figures, in which:
A preferred embodiment of the invention includes a system of interlocking building components to form a shed 99 as shown in the perspective view of
Referring to
Although the panel 100 may be made of any suitable material, it is preferably formed of a polymer, for example, polyvinylchloride (PVC). The compound or mixture may optimally include flame retardants and ultraviolet stabilizers. Preferably, panel 100 is manufactured by a blow molding process to form an integral and completely sealed hollow body. In the blow molding process, a polymer material is melted and extruded through an annular die and then fed vertically down into a hollow mold. Air pressure is applied to the polymer material once it has left the extruder die and entered the mold. The air pressure forces the material against the sides of the mold, thus creating a hollow molding having the shape of the mold. Once the material has cooled and hardened into the mold shape, it is removed from the mold. As blow molding processes are well known in the art, they are not discussed further herein.
A variety of thicknesses may be used for panel 100, where thickness is defined as the distance between planar faces 112 and 114. For example, panel 100 may be thicker or thinner than the thickness of conventionally constructed walls or floors. A panel thickness of about one to two inches should be adequate for most building applications. The two planar faces 112, 114 are preferably sufficiently small so as to maintain the faces in a parallel relation, prevented from bowing by the edges 116, 118, 120, 122, which act as structural ribs for the wall, roof, floor or ceiling constructed of the array of panels. The void spaces within the panels 100 between the planar faces 112, 114 may be injected with an expanding self-curing foam thermal insulation material, if desired.
Although fan-shaped profiles are preferred, various other interlocking arrangements can be used. The dovetail 124 is designed and arranged to slide into and be held tightly by the mortise 154. Other interlocking arrangements are shown in U.S. patent application Ser. No. 10/992,497 and U.S. Pat. No. 5,237,790 of Smalley, which are incorporated herein by reference. Connector element 150 is preferably made from the same material as the shell 28 of panel 10 (
Each connector element 150 ideally has a longitudinal length of w, x, y, z, or 2z to match the edge lengths of the various panels 130, 132, 134, 136, 138 (
Ridge connector 170 ideally has a longitudinal length of x to match the edge lengths of roof panels 134 and wall panels 132 (

While one or more embodiments of the invention have been illustrated in detail, the invention is not limited to the embodiments shown; modifications and adaptations of the above embodiments may occur to those skilled in the art.
