Cl. 52282 5 Claims ABSTRACT OF THE DISCLOSURE BACKGROUND OF THE INVENTION Modular building systems in general are known to the art. However, most of the prior art building systems of the modular type have been strictly utilitarian and functional in appearance, and thus have been unacceptable for residential and other purposes 'where aesthetic values are important. In addition, the prior art building systems have for the most part been difficult to assemble, and have presented serious maintenance problems. However, the ever-increasing material and labor costs involved in the present day building construction, renders it imperative that a low cost modular building system be devised which are acceptable and suitable for residential purposes. The improved building system of the present invention has been provided to answer such criteria.
The modular building system of the invention, as mentioned above, is susceptible to mass production and is, therefore, economical to manufacture. The system is also easy to assemble on the site, requiring no special tools, so that labor costs are held to a minimum. Moreover, the building system of the invention is strong and durable when assembled, and yet may be easily demounted, modified, or added to. A feature of the building system of the invention is the utilization of a minimum of diiferent types of basic components.
Briefly stated, the improved modular building system of the invention is low cost, may be mass produced, and is ligth and durable. Only three basic tools are required to assemble a structure in a practice of the invention, and these are a ball peen hammer, a screw driver and a rubber mallet.
The framing tubular members of the structure of the invention may be precut; and the trim, door frames, window frames, and the like, may be snapped into place in a matter of seconds. When assembled, the resulting building is not subject to termites, dry rot, mildew, rust or any other deleterious influences to which usual building structures are exposed. Moreover, and as will be described, a plastic film, such as polyurethane, may be incorporated into the panels of the structure of the invention, and held firmly in place, to form a moisture barrier, on either side of the wall of the structure or on both sides.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS As shown by the representations of FIGS. 1A and 1B, for example, the framing system of the invention may be made up of a plurality of multilateral tubular members 10 having the illustrated configuration. Each tubular member includes a front longitudinal groove or channel extending along each face, and a smaller groove or channel in the floor of the first channel. The tubular members 10 may be formed of extruded aluminum, or plastic, or other suitable material.
The horizontal tubular member 10, for example, may be supported on a floor either as shown, or by means of an additional strip, as will be described, to extend horizontally, as shown. The upright tubular member 10 may extend vertically, and may serve as a column for the structure.
The tubular members 10 have holes 11 formed in them which are aligned with one another, and with corresponding holes 13 in a U-shaped clip 12, when the clip is inserted in place in the smaller channel of the horizontal tubular member 10. The U-shaped clip 12 is held in place on the horizontal tubular member 10 by means, for example, of structural pins designated 14.
The structural pins 14 are grooved or slotted as shown, and are tapered, so that when the pins are driven into the holes 1'1 and 13, they are firmly retained in place, and there is no tendency for the pins to come loose. However, if so desired, the pins 14 can be driven out of the members, in order to dismantle the structure. With the U-shaped clip 12 and the pins 14 in place, it will be appreciated that the upright column formed by the upright tubular member is firmly and rigidly supported on the horizontal tubular member 10, as shown in FIGS. 1B and 1C.
The beam system for the structure, as shown in FIGS. 2A and 2B, may be formed of a pair of parallel tubular members 10 separated by a flange or web 16. The flange 16 may be formed of aluminum or other appropriate material. The flange 16 has holes 15 in it which receives the structural pins 14 so that the beams are held in a rigid unitary system. As shown in FIG. 2B, for example, the beams are composed of a lower horizontal tubular member '10 and an upper horizontal tubular member 10, separated by the vertical web or flange 16, with the assembly being held in a rigid assembled condition by the structural pins 14. The dimensions of the web 16 are selected to meet different span requirements of the resulting beam.
In FIG. 3A, for example, the tubular member 10 is used as a column at an intermediate position in the wall of a particular structure. The exterior panels of the structure are designated 18, and they extend partially across one face of the upright tubular member '10. The interior panels are designated 20, and they extend partially across the opposite face of te upright column formed by the tubular member 10.
A pair of battens 22 which, likewise, may be formed of extruded aluminum, or other appropriate material, are snapped into the corresponding grooves in the upright tubular member 10, as shown. The battens 22 and the edges of the larger grooves in the tubular member 10 are formed with a hook-like configuration, as shown, so that the battens may be received with a snap action into the respective grooves.
A vinyl seal 24 may be provided between the external batten 22 and the exterior panels 18. In addition, a film 26 formed of polyurethane, or other suitable plastic material, may be interposed between the exterior panels 18 and the column formed by the tubular member I10, as a continuous water or vapor barrier, the film being locked between the batten 22 and the member 10, as best shown in FIG. 3B, as a continuous barrier, and without any fracture of the film itself. When serving as a vapor barrier the film is preferably placed on the warm side of the wall to prevent condensation on the film. However, the film may also be used on the weather side of the wall as a water barrier.
Appropriate insulating blocks 28 of plastic or fiberglass, for example, may be interposed between the exterior panels 18 and the interior panels 20, along the length of the walls, and between successive columns formed by the tubular members 10. The exterior panels 18 may be formed of any available and appropriate building material, as may be the interior wall panels 20.
As mentioned above, the tubular member 10 is shown in FIG. 3C as a corner column, and corner battens 30 and 32 having the illustrated configuration are snapped into place into the grooves in the tubular member, so as to complete the corner of the building. The corner battens 30 and 32 may also be extruded aluminum, or other appropriate material. A batten 22 may be snapped into the left hand side of the tubular member 10 in FIG. 3B. Likewise, a batten 34 of the same or different configuration, as shown, may be interposed between the insulation block 28 and the lower side of the tubular member 10 in FIG. 3C. The battens 22 and 34 serve as supports for the wall panels which may be attached to the battens, by means, for example, of screws 25.
It will be observed in FIG. 3C that the plastic film 26 continues unbroken around the corner of the building so as to provide a continuous moisture seal. As mentioned above, the rfilm may be on the inside of the wall, if so desired.
A slightly different type of system is shown in FIG. 4, in which the cover battens are not used, and a blind panel clip system is utilized instead. The exterior panels 18 in FIG. 4 are shaped differently from FIG. 3A, for example, so as to interlock with one another across the face of the corresponding tubular member 10. Likewise, the interior panels 20 abut onto one another across the opposite face of the column formed by the upright tubular member 10.
A first blind panel clip receptor extrusion 32 is snapped into the left hand side of the tubular member 10 between the tubular member and the corresponding insulation block 28, and a similar blind panel clip receptor extrusion 32 is snapped into the right hand side of the tubular member 10. These latter extrusions may likewise be formed of aluminum, or other appropriate metal or plastic. A second blind panel clip extrusion 34 is interposed between the exterior panel 18 and the remaining components, on each corner of the column assembly, as shown. The latter extrusion may also be formed of aluminum, or other appropriate material. The blind panel clips 34 are attached to the exterior and interior panels, by means of suitable adhesive, screws, or other suitable fasteners or combination of fasteners.
The representation of FIG. 5A is also a blind panel clip system, similar to the system shown in FIG. 4. However, the system of FIG. 5A uses slightly different blind panel clip extrusions designated 36 which are adhesively or otherwise, attached to the exterior and interior panels, and which clip into sockets formed by further blind panel extruded clip receptors 38 which, in turn, fit into the grooves in the side of the columns formed by the tubular members 10.
FIG. 5B shows a corner detail of a similar blind panel clip system to that shown in FIG. 5A. The latter assembly includes a corner batten 40 in conjunction with a corner batten 30 which is snapped into the top and right hand side of the tubular member 10. A blind panel clip receptor extrusion 38 is used between the insulation block 28 and the left hand side of the tubular member 10, and a further extrusion 40 is received in the extrusion 38 to form a clip for the inner panel 20. A similar extrusion 40 is used in conjunction with another clip 38 in the lower side of the tubular member 10, as shown in FIG. 5B.
FIG. 6A is a view like FIG. 3A, but showing with greater clarity, the composition of a typical wall utilizing the concepts of the invention; and FIG. 6B is a view, as mentioned, similar to FIG. 6A, but with the components shown with an exploded representation. FIG. 7, as mentioned above, shows a further detail of a house utilizing the concepts of the invention, and particularly showing the manner in which the roof may be attached to the side walls of the structure.
In FIG. 7, the vertical tubular members 10 form the columns in the framing, and the upper horizontal tubular members 10 are intercoupled, in the manner described in conjunction with FIGS. 2A and 2B, to form beams. The battens 22 may be used between the roof panels 46, for example, as shown in FIG. 7. The plastic film vapor barrier 26 may also extend across the under side of the roof panels, as shown. Exterior, exposed, extruded plastic or metal corner battens 30, 32 may be used at wall corners to fasten the wall panels 18 and 20, as required. Exterior, exposed, extruded plastic or metal snap-in trim members of proper configuration are used at wall corners, door and window heads, jambs, mullions and sills, as well as soflits and facia panels 48.
The roof and ceiling construction of the structure is shown in greater detail in FIGS. 8A and 8B. The roof system, as shown in FIG. 7 and FIGS. 8A and 8B, is developed by the use of the roof panels 46 of any known and suitable type of roof panel material, these being supported by beams formed by the tubular members 10 and intermediate webs 16. The roof panels are fastened to the upper tubular elements 10 by means of battens 22, and by the use of the vinyl seals 24. As mentioned above, the water vapor barrier formed by the plastic film 26 is also used on the roof structure as shown. Plastic or fiberglass insulation blocks 28, for example, are supported under the roof panels 46, by means of blind panel clips 36 which, in turn, are supported by the clips 38, as also shown. The ceiling system 50 is supported adjacent the lower tubular member 10 by means, for example, of appropriate extruded trim clip members 52, or by any other means.
The invention provides, therefore, a four-sided uniform structural tubular ssytem in the form of the tubular members 10, which may be utilized as columns or beams, or space frame members, with snap-in attachment characteristics for utilization in an unlimited number of architectural design and product material systems.
The various tubular members in the framing system are intercoupled with one another, and with the Webs 16 in the beam structures, by means of pins 14 which are grooved and tapered, as described above. This means that the entire framing structure is constructed either by snapping component parts into the grooves in the tubular members 10, or by the use of the tapered pins 14. The tubular members 10 in conjunction with the web or flange member 16 provide for beam systems allowing for various structural loading and snap designs. The exterior wall panel system may be provided with snap-in trim attachment elements to provide a means for fastening the wall panel systems together, as well as for providing a continuous exterior plastic film water seal as described above.
The product items accommodated by the four-sided uniform structural tubular system 10, allowing for a complete modular snap-together system, include the following: mouldings, mullions, jambs, heads, ceiling systems, soffit systems, insulation, wall panels, floor panels, ceiling panels, roof panels, roof systems, heating, ventilating and air conditioning systems and components, electrical conduit, wiring, panels, switches, receptacles, windows, doors, closets, wardrobes, cabinet systems, partitions fixed and movable), stairs, railings, built-in furniture systems, plumbing systems, structural, floor, wall and roof systems, weatherproof roof and wall panel ceiling systems, sound isolation wall panel systems, incombustible and fire rated wall systems, continuous watertight, vapor barrier systems.
The invention provides, therefore, a low cost modular building system accommodating all individual parts as removable, relocatable, replaceable, and additive, as required for modern technological mass production, transportation and assembly.
