Abstract
ABSTRACT OF THE DISCLOSURE
MODULAR CONSTRUCTION SYSTEM
The modular construction system includes a plurality of lightweight, load-bearing composite panels to be used in the walls, ceilings and/or roofs of buildings, as well as for partitions within a given building. Each panel includes sheet-like skins with a foamed plastic core therebetween. At each end of the panel is a structural unit that is fabricated from sheet stock, the structural unit including a transverse sec-tion having a longitudinal groove formed therein. When two panels are abutted in an end-to-end relationship, the grooves form a conduit for electrical wiring, com-munication lines and plumbing. Each structural unit also has a thermal barrier so that the structural unit is resistant to the transmission of heat therethrough.
The panels are connected in their end-to-end rela-tionship by means of interfitting lugs and slots on the structural units. Additional structural units extend across the top and bottom of each panel. The ends of the structural units are interconnected through the agency of additional lugs and slots to form a frame to which the skins are adhered and between which the formed plastic core material is introduced.

Description
1~90543 MODULAR CONSTRUCTION SYSTEM
BACKGROUND OF THE INVENTION
I. Field o_ the Invention This invention relates generally to a modular system for constructing buildings and partitioning them, and pertains more particularly to such a system using panels which contain within themselves all elements required to support weight and provide insulation con-fined by an interior and exterior skin.
II. Description of the Prior Art The use of composite panels utilizing a core of foam insulation and various types of facing or skin material, of course, are not new. While such panels possess some load-bearing capabilities, such capabili-ties are considerably restricted. Building codes have not accepted these panels as being sufficient in and of themselves for use in "stand alone" environments. When this type of panel is used in a wall construction, some form of separate supporting structure must be used in order to provide sufficient load-carrying capabilities for the wall. Likewise, when used in roof construc-tions, the panels are applied over rafters.
Consequently, there remains a real need for a construction system utilizing panels that do not require an added supporting structure, such as posts, studs, beams and braces which add appreciably to the material and on-site assembly costs.
The composite or laminated panels found on the market today have represented to a large degree a compromise between a fully acceptable panelized construction system and the inefficiency and costliness of the widely used stick-built construction that has been employed for many years.
1~9(~5~3 _m _ y of the Invention A general object of rny invention is to provide a modular construction system that will reduce the on-site construction costs, whether such construction is associated with the erection of an entire building or in the assembly of partitions within a particular building.
In this regard, an aim of the invention is to fabricate individual panels at the factory in such a way that they can be assembled very rapidly and with little effort at the location wherc they are used.
Also, the invention has for an object the fabrication of the panels at the factory, utili%ing techniques that minimize the cost of labor and materials, the factor-derived savings being in addition to the savings in costs by reason of the reduced time and effort in assembling the panels after they have been shipped from the factory to the site where they are to be utilized.
A very important object of my invention is to provide individual panels that when connected together can withstand normal load conditions. In this regard, it is within the purview of my invention to employ load-bearing structural units along all four edges of the panel. In this way, the structural units at the ends of the panel, when fastened together, obviate the need for individual studs, posts, splines or braces of any kind.
Also, the structural units, when the panels are fastened together, are completely concealed. Still further, the structural unit extending along the top and the one extending along the bottom, provide added rigidity that can be utilized in connecting either the upper ends or the lower ends of the panels to superjacent or subjacent structures.
Another important object of the invention is to employ structural units at the opposite ends of the lX90~fl3 panels such that when one end of a panel is connected or fastened to another panel vertical voids are formed that can be used as raceways for electrical wiring, com-munication lines and piping.
Yet another object of the invention is to pro-vide load-bearing panels that are extremely light in weight. In this regard, the panels are fabricated with structural units that are of a thin wall construction.
Coupled with the lightweight character of the structural units is the use of a foamed core faced on opposite sides with relatively thin and inexpensive covering skins. The unique structural units in combination with the foamed core and overlying skins or facing material produce an exceptionally lightweight, yet rugged, modu-lar unit.
Still further, the invention has for an objectthe use of thermal barriers and weather seals which make the panel walls and roofs weathertight without requiring on-the-job caulking or filling. Thus, a panel constructed in accordance with the teachings of my invention will be energy efficient, thereby reducing the amount of heat required in cool weather and the amount of air conditioning needed in warm weather.
Briefly, my invention envisages the employment of structural units extending along all four edges of a panel, the structural units being totally concealed when the panels are assembled. The structural units are fabricated of thin wall metal in the form of two channel members. On leg section of one channel member has a groove formed therein, this leg section extending trans-versely toward an inwardly directed leg section belonging to the other channel member but terminating in a space relationship therewith so as to permit the use of a thermal barrier between the free edges of these two leg sections. The other leg sections of the two channel ~X9~S4~
members in each instance are spaced so that the foamed plastic insulating material constituting the core can pass therebetween and into the void formed by the two channel members. The channel members included in the structural unit of one end of each panel are provided with projecting lugs and the channel members forming the structura] unit of the opposite end of each panel are provided with slots so that the panels can be fastened together at the job site by means of the lugs and slots when arranged in an end-to-end relationship. Additional lugs and slots are employed to connect the top struc-tural unit to the two vertical end structural units at the factory and likewise additional lugs and slots are used to connect the bottom structural units to the lower ends of the vertical units during the fabrication pro-cess. In this way, a skeleton-type frame is formed and when the skin or facing members, such as sheets of appropriate hardboard, are held against the resulting frame, the introduction of foamed plastic will cause the space between the skins to fill and also the space within the structural units extending along the four sides of the frame.
Although my invention will hereinafter be described in conjunction with a panelized modular wall construction system, it will be recognized that the invention can be used to form the ceiling for a room or the roof of a building. In other words, the individual panels are fabricated so that they can be interconnected vertically, such as when erecting the wall of a building or a partition within a building, horizontally when constituting the ceiling of a room, or at an inclination when forming the roof of a dwelling.
Brief Description of the Drawings Figure 1 is a front elevational view of a modular construction system exemplifying my invention, the construction being in the form of a wall.

Figure 3 is a sectional detail taken in the direction of line 3-3 of Figure 1 in order to show the similarity between the structural unit extending hori-zontally along the top of each panel and the verticalstructural units at the ends of the panels (as in Eigure 2), and Figure 4 is an open book perspective view of the portions of two skeleton-type frames, without either skin having been applied and without any foamed plastic having been introduced, the view not only depicting the manner in which the frames are fabricated but also the manner in which the finalized panels are interconnected by the lug and slot arrangement appearing in this view.
Description of the Preferred Embodiment Although my invention can be used in the construction of ceilings and roofs, Figure 1 depicts a wall construction utilizing the modular techniques of my invention, the wall construction being indicated generally by the reference numeral 10. More specifi-cally, the wall construction 10 includes four complete panels 12 and two fragmentarily pictured panels 12.
Each of the panels 12 is of identical construction. In this regard, each panel 12 includes a frame 14 comprised of a vertical structural unit i6 at the right end thereof, and a vertical structural unit 18 at the left end thereof, the unit 18 being virtually a mirror image of the unit 16~ Additionally, there is a structural unit 20 at the top and a structural unit 22 at the bot-~290S43 tom of each frame. As the description progresses, itwill be appreciated that the units 20 and 22 can be identical to each other, and also virtually identical to either the unit 16 or the unit 18. Although no top plate is shown in Figure 1, a sole plate or bottom plate 24 underlies the bottom unit 22 of the panels 12.
The similarity between the structural units 16 and 18 can be readily appreciated from Figure 2, and also from Figure 4. Owing to this similarity, it will be easier to assign the same reference numeral to each corresponding part. Consequently, there is a first channel member 26 of sheet metal that includes a web section or side plate member 28, a first leg section 30 and a second leg section 32. The first leg section 30 includes a strip portion 34 having a semicircularly curved inwardly protruding conduit defining portion 36 forming a longitudinal groove 38. As shown in the drawings, strip portion 34 is a vertical edge plate member extending perpendicular inward from an outer edge 28' of side plate member 28. (For purposes of this application, "inwardly" and "inward" will mean pro-jecting away from exterior surfaces of a panel 12.) Additionally, the first leg section 30 includes a flange portion 40 that is integral with the curved portion 36, thereby forming a free edge at 42. The second leg sec-tion 32 constitutes a flange in and of itself extending inwardly from inner edges 28'' of side plate member 28 and having a free edge labeled 44.
There is a second channel member 46 having a web section or side plate member 48, a first leg section 50 and a second leg section 52. In this instance, the first leg section 50 includes a strip portion 54 integral with the web section 48 and a flange portion 56 providing a free edge at 58. As shown in the drawings, strip portion 54 is vertical edge plate member extending 1~90543 perpendicularly inwardly from an outer edge 48' of side plate member 48. The second leg section 52 is in the form of a flange projecting inwardly from an inner edge 48'' of side plate member 48 and provides a free edge 60.
It should be observed that the first ]eg sec-tion 30 of the channel member 26 terminates in a spaced relationship with respect to the first leg section 50 of the second channel member 46. In other words, the free edge 42 of the flange portion 40 is spaced from the free edge 58 of flange portion 56. By the same token, although to a far greater degree, the second leg section 32 of the first channel member 26 terminates in a spaced relationship with respect to the second leg section 52 of the channel member 46. Here again, the free edges 44 and 60 are spaced from each other, the spacing being quite substantial as can be learned from Figures 2 and 4.
At this time, attention is directed to a ther-mal barrier in the form of an elastomeric strip 62having a longitudinal groove at 64 and a second longitu-dinal groove at 66, the grooves 64 and 66 facing in opposite directions as can be clearly perceived from Figures 2 and 4. The groove 64 snuggly receives therein the flange portion 40 and the groove 66 snuggly receives therein the flange portion. In this way, there is a substantial resistance to the flow of heat between the two leg sections 30 and 50, and hence inhibiting the transfer of heat from one side of the panel 12 to the other via this path. When the ends of two completed panels 12 are abutted together, as can be understood from Figure 2, a weather seal 67 is employed between the flange portions 56.
As can be seen at the left in Figure 4, there is a lug strip 68 appearing in phantom outline inasmuch ~290S4~
as it is concealed by the second channel member 46 of the structural unit 16; although not shown, a second lug strip 68 is secured to the web section 28, providing additional lugs 72. The lug strip 68 has any preferred number of L-shaped lugs 72 projecting therefrom through slots 70 formed in the strip portion 54, each lug 72 having a horizontal section 74 and a vertical section 76, thereby forming a slot at 78. The lug strip 68 is secured to the web section 48, as by welding. The strip portion 34 belonging to the first channel member 25 of the structural unit 18 and the strip portion 54 of the second channel member 46 each has a number of slots 78 therein which enable the horizontal section 74 of each lug 72 to extend therethrough. In this way, the L-shaped lugs 72 of the structural unit 16 function ashooks, being engageable when inserted into the vertical slots 78 of the structural unit 18, as can be understood from Figure 4. Although only two L-shaped lugs 72 appear in Figure 4 and only two slots 78 appear in this figure, it will be appreciated, as already indicated, that any desired number of L-shaped lugs 72 can be ver-tically oriented on the unit 16 and any corresponding number of slots 78 in the unit 18 can be appropriately oriented so as to fasten the adjacent ends of two panels 12 together.
It has already been stated that the structural unit 20 is very much like, or can even be identical to, the units 16 and 18. Therefore, the portions of the two structural units 20 appearing in Figure 4 have been assigned the same reference numerals utilized when describing the structural units 16 and 18. However, no lugs 72 or slots 78 have been shown, for the manner in which the structural units 20 are to be attached to a top plate or other superstructure depends upon the par-ticular architectural design of the building. When the 1290~i~3 panels 12 are used as a partition, it should beunderstood that there would be no panels 12 thereabove and consequently there would be no need for any means for interconnecting the structural units 20 of any of the panels 12 to something thereabove. The same thing holds true for the bottom structural unit 22.
However, it should be observed from Figure 4 that there is a lug bracket 80 that is secured as by welding, to the inner surface of the web section 48 belonging to the second channel member 46 of the struc-tural unit 16 and a lug bracket 80 si.milarly secured to the web section 48 belonging to the second channel member 46 of the unit 18. Each lug bracket 80 has an L-shaped lug 82 projecting from the end thereof, the L-shaped lug 82 having a horizontal section 84 and avertical section 86, thereby forming a slot 88. There are slots 90 in the second section 52 of the second channel member 46 of the structural unit 16 and also in the section 52 of the second channel member 46 of the unit 18. Although not shown, there is a second lug bracket 80 secured to the web section 28 of each channel member 26. Thus, when initially connecting the various structural units 16, 18, 20 and 22 together to provide a frame 14, the L-shaped lugs 82 are inserted into the slots 90 to produce each frame 14.
Interior and exterior skin or facing sheets 92 and 94, such as tempered fiberboard, have marginal por-tions thereof overlying the section 48 and 28 respec-tively, of the channel members 46 and 26 and presenting vertical. edges 92', 94', respectively, in planar align-ment with edges 54 and 34. Actually, these skins 92, 94 are suitable adhered to the web sections 48, 28 before introducing any foamed plastic 96, such as polyurethane, into the void between the skins 92, 94, and also within the space formed within the various structural units 16, 18, 20 and 22. It will be appre-~29(~543 ciated, especially from Figure 2, that the foamed plastic, while still molten enters the voids of the units 16-22 between the second sections 32 and 52 of the two channel members 26 and 46.
It should be appreciated that when the panels 12 are assembled, that is placed end to end, there is a vertically oriented cylindrical conduit or raceway 98 formed by reason of the two curved portions 36~ This void or raceway 98 can readily accommodate electrical wiring, communication lines and/or piping. In this regard, the upper ends of the curved portions 36 of the structural units 16 and 18 are curved downwardly so as to conform to the curved portions 36 of the horizontal structural units 20. More specifically, such a confor-mity enables whatever wiring or piping is contained inthe vertical conduit 98 to pass into either or both grooves 38 in the units 20. During the forming proce-dure, the upper ends of the structural units 16 and 18 would be suitably blocked and such a blocking means would include a semicylindrical portion thereon so that communication is established between the conduit 98 and the horizontal grooves 38 in the units 20.

Description of the Preferred Embodiment Although my invention can be used in the construction of ceilings and roofs, Figure 1 depicts a wall construction utilizing the modular techniques of my invention, the wall construction being indicated generally by the reference numeral 10. More specifi-cally, the wall construction 10 includes four complete panels 12 and two fragmentarily pictured panels 12.
Each of the panels 12 is of identical construction. In this regard, each panel 12 includes a frame 14 comprised of a vertical structural unit i6 at the right end thereof, and a vertical structural unit 18 at the left end thereof, the unit 18 being virtually a mirror image of the unit 16~ Additionally, there is a structural unit 20 at the top and a structural unit 22 at the bot-~290S43 tom of each frame. As the description progresses, itwill be appreciated that the units 20 and 22 can be identical to each other, and also virtually identical to either the unit 16 or the unit 18. Although no top plate is shown in Figure 1, a sole plate or bottom plate 24 underlies the bottom unit 22 of the panels 12.
The similarity between the structural units 16 and 18 can be readily appreciated from Figure 2, and also from Figure 4. Owing to this similarity, it will be easier to assign the same reference numeral to each corresponding part. Consequently, there is a first channel member 26 of sheet metal that includes a web section or side plate member 28, a first leg section 30 and a second leg section 32. The first leg section 30 includes a strip portion 34 having a semicircularly curved inwardly protruding conduit defining portion 36 forming a longitudinal groove 38. As shown in the drawings, strip portion 34 is a vertical edge plate member extending perpendicular inward from an outer edge 28' of side plate member 28. (For purposes of this application, "inwardly" and "inward" will mean pro-jecting away from exterior surfaces of a panel 12.) Additionally, the first leg section 30 includes a flange portion 40 that is integral with the curved portion 36, thereby forming a free edge at 42. The second leg sec-tion 32 constitutes a flange in and of itself extending inwardly from inner edges 28'' of side plate member 28 and having a free edge labeled 44.
There is a second channel member 46 having a web section or side plate member 48, a first leg section 50 and a second leg section 52. In this instance, the first leg section 50 includes a strip portion 54 integral with the web section 48 and a flange portion 56 providing a free edge at 58. As shown in the drawings, strip portion 54 is vertical edge plate member extending 1~90543 perpendicularly inwardly from an outer edge 48' of side plate member 48. The second leg section 52 is in the form of a flange projecting inwardly from an inner edge 48'' of side plate member 48 and provides a free edge 60.
It should be observed that the first ]eg sec-tion 30 of the channel member 26 terminates in a spaced relationship with respect to the first leg section 50 of the second channel member 46. In other words, the free edge 42 of the flange portion 40 is spaced from the free edge 58 of flange portion 56. By the same token, although to a far greater degree, the second leg section 32 of the first channel member 26 terminates in a spaced relationship with respect to the second leg section 52 of the channel member 46. Here again, the free edges 44 and 60 are spaced from each other, the spacing being quite substantial as can be learned from Figures 2 and 4.
At this time, attention is directed to a ther-mal barrier in the form of an elastomeric strip 62having a longitudinal groove at 64 and a second longitu-dinal groove at 66, the grooves 64 and 66 facing in opposite directions as can be clearly perceived from Figures 2 and 4. The groove 64 snuggly receives therein the flange portion 40 and the groove 66 snuggly receives therein the flange portion. In this way, there is a substantial resistance to the flow of heat between the two leg sections 30 and 50, and hence inhibiting the transfer of heat from one side of the panel 12 to the other via this path. When the ends of two completed panels 12 are abutted together, as can be understood from Figure 2, a weather seal 67 is employed between the flange portions 56.
As can be seen at the left in Figure 4, there is a lug strip 68 appearing in phantom outline inasmuch ~290S4~
as it is concealed by the second channel member 46 of the structural unit 16; although not shown, a second lug strip 68 is secured to the web section 28, providing additional lugs 72. The lug strip 68 has any preferred number of L-shaped lugs 72 projecting therefrom through slots 70 formed in the strip portion 54, each lug 72 having a horizontal section 74 and a vertical section 76, thereby forming a slot at 78. The lug strip 68 is secured to the web section 48, as by welding. The strip portion 34 belonging to the first channel member 25 of the structural unit 18 and the strip portion 54 of the second channel member 46 each has a number of slots 78 therein which enable the horizontal section 74 of each lug 72 to extend therethrough. In this way, the L-shaped lugs 72 of the structural unit 16 function ashooks, being engageable when inserted into the vertical slots 78 of the structural unit 18, as can be understood from Figure 4. Although only two L-shaped lugs 72 appear in Figure 4 and only two slots 78 appear in this figure, it will be appreciated, as already indicated, that any desired number of L-shaped lugs 72 can be ver-tically oriented on the unit 16 and any corresponding number of slots 78 in the unit 18 can be appropriately oriented so as to fasten the adjacent ends of two panels 12 together.
It has already been stated that the structural unit 20 is very much like, or can even be identical to, the units 16 and 18. Therefore, the portions of the two structural units 20 appearing in Figure 4 have been assigned the same reference numerals utilized when describing the structural units 16 and 18.

The same thing holds true for the bottom structural unit 22.
However, it should be observed from Figure 4 that there is a lug bracket 80 that is secured as by welding, to the inner surface of the web section 48 belonging to the second channel member 46 of the struc-tural unit 16 and a lug bracket 80 si.milarly secured to the web section 48 belonging to the second channel member 46 of the unit 18. Each lug bracket 80 has an L-shaped lug 82 projecting from the end thereof, the L-shaped lug 82 having a horizontal section 84 and avertical section 86, thereby forming a slot 88. There are slots 90 in the second section 52 of the second channel member 46 of the structural unit 16 and also in the section 52 of the second channel member 46 of the unit 18. Although not shown, there is a second lug bracket 80 secured to the web section 28 of each channel member 26. Thus, when initially connecting the various structural units 16, 18, 20 and 22 together to provide a frame 14, the L-shaped lugs 82 are inserted into the slots 90 to produce each frame 14.
Interior and exterior skin or facing sheets 92 and 94, such as tempered fiberboard, have marginal por-tions thereof overlying the section 48 and 28 respec-tively, of the channel members 46 and 26 and presenting vertical. edges 92', 94', respectively, in planar align-ment with edges 54 and 34. Actually, these skins 92, 94 are suitable adhered to the web sections 48, 28 before introducing any foamed plastic 96, such as polyurethane, into the void between the skins 92, 94, and also within the space formed within the various structural units 16, 18, 20 and 22. It will be appre-~29(~543 ciated, especially from Figure 2, that the foamed plastic, while still molten enters the voids of the units 16-22 between the second sections 32 and 52 of the two channel members 26 and 46.
It should be appreciated that when the panels 12 are assembled, that is placed end to end, there is a vertically oriented cylindrical conduit or raceway 98 formed by reason of the two curved portions 36~ This void or raceway 98 can readily accommodate electrical wiring, communication lines and/or piping. In this regard, the upper ends of the curved portions 36 of the structural units 16 and 18 are curved downwardly so as to conform to the curved portions 36 of the horizontal structural units 20. More specifically, such a confor-mity enables whatever wiring or piping is contained inthe vertical conduit 98 to pass into either or both grooves 38 in the units 20. During the forming proce-dure, the upper ends of the structural units 16 and 18 would be suitably blocked and such a blocking means would include a semicylindrical portion thereon so that communication is established between the conduit 98 and the horizontal grooves 38 in the units 20.
