Abstract

The building structure utilizes prefabricated frame components of equal heights in forming the external and internal framing systems. The basic frame components include a structural post, blank wall frames, window frames, door frames and end caps. Each of the frame components is elongated and is provided with a laterally extending elongated male connector along one vertical edge and a pair of horizontally extending structural members at the top and bottom of the frame component forming a female receptacle on the other vertical edge whereby the male connector on each of the frame components fits into the female receptacle of an adjacent frame component and is secured thereto. Each frame component has load bearing capabilities and may be used interchangeably as members of interior or exterior walls. Each frame component utilizes manufactured elements which are commercially available and which require a minimum amount of work thereon, if any, in order to utilize same in the frame components. Identical manufactured parts are utilized in assembling the frame components and there is a regular rhythm of spacing the vertical studs or members of the frame components to insure ''''on center'''' dimensions when compared with present panel constructions. In erecting the frame components, there is a constant repetition of identical components with the male connector of one component mating with a femal receptacle on adjacent components and thereafter the components are tied mechanically together. Outer sheathing and inner wall boards are secured to the external and internal frame structures. Ceiling boards are secured to the roof trusses provided on the framing system.

8 Sheets-Sheet 8 STRUCTURAL CORNER POST AND FRAMING SYSTEM FOR BUILDINGS BACKGROUND OF THE INVENTION During the past decade there have been programs designed for lowering the cost of constructing buildings. The emphasis of such programs is placed primarily on buildings designed for residential use. Individual entrepreneurs as well as large industrial and commercial firms have attempted to find solutions to the problem of constructing economical buildings and houses. The avowed objective of each program is to produce a better house for less cost.

The term manufactured housing has been used during the last several years. The basic assumption is that only by building houses in factories can solutions be found to rising costs. Such an assumption indicates a misunderstanding of the term manufactured housing as well as its meaning. It is submitted that houses cannot be manufactured any more than an automobile or a toaster is manufactured. Automobiles and toasters are assembled from parts that are manufactured. Thus buildings and houses are assembled and not manufactured.

Only parts can be manufactured i.e. made by machine. Only a high volume of identical parts makes manufacturing economical. Manual operations are rarely replaced by a machine operation until the market for such parts made by man reach a potential volume that will not only provide a return on the investment in the machine but in addition will yield a profit.

The baisc problem with housing is not that there is too little manufacturing; but, too much. Every single component that a house requires is already. being manufactured in factories. Too frequently these products are simply manufacturing blanks in the hands of the builder and the subcontractors who practice their craft by re-manufacturing with their ancient hand tools what machines produced. Some products are used in a house precisely as they were manufactured or factoryassembled, products such as nails, switch plate covers, toilets, appliances and doorknobs. But the products that are used in framing the house and covering the frame are typically measured, marked, and cut. Until then the 2 X 4 inch lumber, gypsum board, insulation batt and exterior siding may never have been handled by man. Even such a mundane item as a pine 2 X 4 inches is a product of a capital-intensive, highly sophisticated processing industry and it comes to the carpenter in a far more finished, dimensionally true state than its hand-hewn predecessor did not toomany years ago. However, by the time the carpenter is finished measuring, marking, sawing, drilling, notching, routing, shimming and otherwise remaking the lumber, much of the manufacturing economies inherent in that piece of lumber are lost. A person rarely finds a high enough quantity of such parts in a house that are precisely identical to attract somebody to manufacture the parts in final form.

It is on individual parts that the present invention focuses. If housing is to be revolutionized, the emphasis must be placed on every single component that goes into the production of the building. Only by offering industry high volume of identical parts can housing attract the investment required for even more sophisticated machines than are presently available; lure technologies that exist but are not being applied to housing;

and, unleash the research and development expenditures that must be forthcoming if housing is to catch up with at least the machine, if not the space age.

Most manufactured housing firms concentrate almost exclusively on trying to achieve substantial labor savings vis-a-vis conventional, on-site construction. The techniques used, however, are usually limited to hiring non-skilled workmen so that lower-than-field wages can be paid. The materials being used and the methods of fabrication are customarily the same as one finds on a conventional building site. There are several fallacies in this approach. Among them, as discussed hereinafter, is the assumption that reducing labor costs alone will more than offset the investment and cost penalties that builders incur when they elect to build houses in factories. These cost or investment penalties versus conventional construction firms come in the form of land and building for the plant; tooling; administrative and production overhead; special freight problems and costs; and, the unique unique for the construction industry problem of having to selffinance their entire inventory. Perhaps the most serious but least acknowledged penalty comes in the form of restrictions on design. The manufactured house is frequently so unattractive aesthetically that it borders on being non-competitive at any price.

The most serious error that housing manufacturers typically make is exaggerating labors share of the total cost of construction. Analyses by the Kaiser Commission outline construction costs of single-family residences as: labor 18 percent; material 38; development 30; overhead and profit 14; for a total percent.

By extrapolation, the analysis suggests that 8 percent of the l8 percent of labor input is associated directly with development, c. g. excavating and building foundations, back-filling, hooking up utilities. The balance of labor costs only 10 percent of total costs is associated directly with the structure; only this portion can be moved into a plant. Even if in-plant operations could yield a 50 percent reduction in labor costs, the net impact on total costs would be only 5 percent. The effect on total monthly occupancy costs is even less impressive. A 50 percent reduction in house-related labor would lower a homeowners monthly costs by less than 3. percent. In search of such savings, however, it is common to. make a substantial investment in plant, tooling and equipment. These costs, plus the other cost penalties referred to earlier, are severe handicaps for the housing manufacturer because they are all in excess of what his competitor the traditional builder has invested. Just amortizing the investment and paying for the highoverhead (again, relative to his competition) will more than offset any labor savings, and it is not clear whether he is even achieving the latter.

Because of inadequate analysis of the trade-offs between the immense investment in plant and (theoretical) labor savings, large losses have been experienced by otherwise capably managed companies who have ventured into manufactured housing. Many have ceased to dobusiness in the housing field because of serious financial losses.

There are two principal categories of firms which are attempting to build houses in factories: (a) those which assemble the entire house in the factory, usually in two sections, truck it to a site, set it on its foundation, and make final connections; and (b) those classified as component manufacturers; the latter customarily take one of two forms, or perform both types of operations:

1. Component manufacturers fabricate whole walls, complete with insulation and wiring, windows and doors, and exterior and interior wall sheathing installed in the factory. Usually cranes are required for final assembly of the wall components on site; and

2. Other component manufacturers fabricate smaller sections of the wall, usually referred to as panel manufacturers, with sheathing, insulation, wiring and exterior siding left for installation on site.

The latter type of operation is most akin to the subject invention in the sense that the product of such a component manufacturer typically follows a modular scale. The panels usually are offered in lengths such as 2 feet, 4 feet, and 8 feet. Such panels are, however, usually closed at both ends. As a result, there are material cost penalties since there is a doubling up of end studs where two panels abut. Also, this type of joint and internal assembly complicates their assembly and the engineering of assembly tools and processes. The main reason is that a regular rhythm of spacing between studs is not maintained; i. e. on center dimensions are not constant. This kind of a butt joint also requires in some applications special efforts to insulate the butt seam. Of course, manufacturing and assembly economies are reduced to their lowest level by those panel fabricators who build any size panel that a customer may choose to specify.

SUMMARY OF THE INVENTION This invention relates to the use of prefabricated frame components used in the erection of the internal and external framing systems of houses, low-rise apartments, office buildings, light industrial buildings and schools.

The basic framing components include a structural column or corner post, blank wall assemblies or wall frames, window frames and door frames and end caps. The framing structure or system utilizes top and bottom horizontal framing parts (plates) that are of the same dimension. Vertical support members or studs are located on center and vary in length only when used to support sills in windows or door frames. Each of these components has load-bearing capabilities and may be used as members of interior or exterior walls, interchangeably.

Comer support and structural integrity are provided by the column or corner post designed to receive the male end of the framing component from one side and, at a 90 angle to the male, a female end of another framing member or component. The corner post may be reversed, i.e., turned upside down, and used for a reverse configuration of wall members. This permits the same column or corner post to be used for inside or outside corners without modifications required for the column or the sub-assemblies that abut it. The same corner post without modifications is also used in certain applications for joining intersecting members of interior walls. Any one of the framing members or components may be connected at right angles to any other by simply inserting the male end or connector anywhere next to or between the vertical members along the horizontal plane of the member or component which it is joining or by abutting the female end to the member or component anywhere along the horizontal plane. The end cap is used to close the female end or female receptacle of a wall member or frame component as may be required in some applications. It is identical in length to the vertical supports or studs used in the frame components.

The various frame components are joined together via a C-type butt joint on the horizontal plane that overlaps a vertical support member or stud both at the top andbottom. Various frame components are connected together with the conventional top plate, each section of which would butt approximately 12 inches or more from any butt joint formed by the wall members or frame components.

The framing system requires as few as eight different parts from which all components can be assembled, namely the post, blank wall members, window frames, door frames, and the end caps. The system includes a constant repetition of identical parts which are manufactured in volume. Use of identical parts is the absolute prerequisite for economical manufacturing. Production capability is increased since eight machines, very simple in design, could be used to make the eight parts. Tooling costs would beminimized since each machine performs only one operation, which typifies the least expensive and most efficient machine of all.

In the framing system there is a regular rhythm of spacing between full length, vertical wall members or components which makes assembly particularly easy. Sheathing may be applied to the framing system with virtually no modification required in most instances. This permits manufactured materials such as the typical 4 X 8 foot gypsum and insulation-type wall boards to be used as finished products on the framing system without alterations.

Another feature of the present invention is that the framing members may be produced economically either in a plant, where the advantage may be production and inventory control, or on the building site. In addition the system is equally adaptable to a conventional stick building, as well as the typical in-plant type of operation. Depending on the size of the structure, a building could be enclosed on the site within one day thus permitting some flattening of the building cycle that results from climatic conditions and tend, therefore, to increase the overall productivity of the housing industry.

The roof trusses 22 are mounted on the framing system and spaced on 24 inch centers as stated previously. Each gable type building structure includes various wall boards and sheathing at the ends of the building structure between the top plates 160 and the roof structure as represented generally by the numeral 162 in FIG. 1.

FIG. 3 illustrates the male-female connections or C- type butt joints provided between adjacent wall components, with the conventional top plates 160 spanning the exterior framing structure 14 as well as the interior framing structure 16. Each top plate 160 has a cross section of ll inches X 3-% inches and can vary in length. Each wall component has a height of 7 feet 11 inches. The overall height from the slab 12 to the top surface of plate 160 is 8% feet.

As stated previously, the present invention utilizes certain parts manufactured in volume from commercially available lumber. Several component parts having a predetermined length and cross section are used for economy purposes. The component parts of each frame component are tied together by nails. Abutting frame components also are tied together by nails which are driven through the C-type butt connection as appears in FIG. 12. The top plates 160 are tied to the frame components by nails properly placed.

The dimensional configuration of the several parts used in the manufacture of the frame components are as follows:

The outer sheathing 18 is commercially available in sheets of a size 4 feet X 8 feet X A inch. The sheathing 18 is erected or applied to the framing system 14 with virtually no modification requircd in most cases except to fit around door and window openings. The wall boards 20, as an example, gypsum and insulation-type wall boards, are commercially available in 4 feet X 8 feet X /2 inch sheets. The wall boards 20 are used as purchased with the exception when applied to door frames and window frames. In such instances the boards must be cut to required size.

It will be noted in FIG. 12 that after a pair of angularly related structural members 98 of adjacent wall frames 38 are tied to the corner post 34, the inner corner 166 of the upper end plate 50 and the inner comer 168 of the lower end cap 52 of corner post 34 are exposed and each provides a pair of

vertical surfaces

170, 172 located at 90. Such surfaces 1'70, 172 each has'a height of l- /z inches and a width of A inch and forms a stop surface for the inner wall boards 20 as illustrated in FIGS. 14 and 15.

The

vertical surfaces

170, 172 on the corner posts 34 and the vertical studs of the several frame components provide nailing surfaces in order to connect the outer sheathing or sheets 18 and the inner wall boards 20 to the frame components. The sheathing and wall boards are manufactured in 4 feet X 8 feet X inch sheets. The boards may be arranged vertically as illustrated in FIG. 13 or horizontally. In FIG. 13 the outer sheathing 18 extends from the ground or slab 12 to a point onehalf inch below the top surface of the conventional top plate 160. The wall board 20 also extends from the slab 12 to one-half inch below the top surface of the top plate 160. The outer sheathings 18 are connected to the vertical studs of the frame components which are located on 16 inch centers. The wall boards 20 abut the

vertical surfaces

170, 172 of the corner posts 34 and are connected to the vertical studs of the frame compo nents. Since the vertical studs of the internal and

external framing systems

14, 16 are accurately located on 16 inch centers, the workman needs only to measure from the corner posts along each wall after the sheathings l8 and wall boards 20 are put in place in order to locate the vertical nailing surfaces provided on the vertical studs. The ceiling board 180 illustrated in FIG. 13 is in the form of a 4 feet X 8 feet X V1 inch sheet. The ceiling boards 180 abut the horizontal stringers 24 provided on the trusses 22. The edges of the ceiling boards 180 abut the top edges of the wall boards 20, with the outer surfaces of the ceiling boards 180 being flush with the outer surface of the top plates 160. The ceiling boards 180 may be secured to the horizontal stringers 24, located on 24 inch centers, by nails.

Vertical end caps 94' are utilized to close the female ends of the wall frames 38 as illustrated in FIG. 14. In addition, end caps 94' are provided in certain applications where the female ends of two or more interior or exterior wall frames 38 come together and where the female end of a wall frame 38 connects to the exterior framing system. FIGS. 14 and 15 illustrate the manner of using nails 182 to attach the outer-sheathings 18 and wall boards 20 to the vertical studs of the interior and

external framing systems

14, 16.

ner post and end caps would remain the same. The only difference would be that the vertical studs of the frame components would be increased in length or extended l- /2 inches. With such a construction the conventional top plates are eliminated in both the internal and external framing systems. To compensate for the removal of the l-% inch top plate 160 and still maintain a rough wall height of 8-% ft. (to accommodate conventional manufactured wall covering materials which commonly come in increments of 4 foot widths, 8 foot lengths and one-half inch thickness), the vertical studs of each frame component would be lengthened by l-% inches.

The 24 inch on-center pattern is gaining acceptance in the United States as members of the building trades seek effective ways of lowering construction costs without sacrificing structural integrity. With floor joists, wall studs and roof trusses all on 24 inch centers a rhythmic band of structural members rings the entire building. The present system is readily adaptable to this trend. A material cost reduction would result since the top plates 160 are eliminated in addition to one stud per each 4 foot blank wall frame. The roof trusses, located on 24 inch centers, would rest directly on the frame components.

When properly fabricated and erected the system would permit framing-in an entire structure of approximately l,5002,000 square feet within one day. Most importantly framing the walls, both interior and exterior, could be accomplished with little more than a hammer. When precisely made, components of the system square and plumb each other at time of connecting together. The entire wall structure can be erected with- -out a measuring tool or marking device, a saw, a drill,

or a square; thereby several of the most labor-intensive activities associated with building construction are eliminated. Theoretically, even a level may be unnecessary except as a quality control gauge.

The use of the framing system is not dependent upon the availability of any particular building material. As a result, the framing system could be constructed from any material that has load-bearing characteristics that may be found locally. The framing system need not be assembled by skilled tradesmen since it is particularly useful for self-help building projects or for building in areas where there is a short supply of building tradesmen. 1

Dimerisionally, the framing system is sized to accept conventional wall covering materials such as gypsum board and exterior sheathing with a minimum of modification to such products; also, to accept conventional plumbing and electrical components; and at the same time, the engineering principles incorporated make the framing system adaptable to change that may subsequently occur in any one of the frame components which require the frame for support. The vertical supports or studs can be moved closer or further apart, the plate can be lengthened or shortened or altered in other ways, as can the vertical members, in width or any other dimension, without departing from the basic concept of the invention.

The framing system incorporates a high degree of dimensional standardization, and thus lends itself readily to the design and building of simple tools for fabricating its members and for assembling its parts.

The costs of both material and labor for framing in a house or other type of building structure should be equal to or less than for conventional constructions. The framing system due in part to using manufactured parts and by locating the studs on center provides a better structure in terms of strength and the structure is adapted to be expanded without costly probing of the walls to determine stud locations. In addition the framing system permits the exchange of any one of its framing members for another (or simply interchanging existing members).

The variety of local and state building codes in the United States is considered to be a major obstacle in aggregating a national housing market from which could be derived the maximum economies available from manufacturing. With the present framing system the most stringent structural building codes in the United States as well as in neighboring countries would be met. Thus the system is universally applicable, without alienating local building departments, zoning boards, or trade unions. Due to its open type construction, the framing system accommodates state and local electrical or mechanical construction codes.

The frame construction 200 illustrated in FIG16 may be used in the building structure where a large picture type window opening or a sliding door construction is required. The frame construction 200 includes portions of a pair of wall frames 38 which are separated by an upper bridge or spanner device 204 and by a lower spanner element 205. The end portions 206 of the top and

bottom plates

96, 98 of the left wall frame 38 overhang a distance of l-%inches from vertical stud 94. The vertical stud 94 of the right wall frame 38 extends or overhangs a distance of three-fourth inch.

The bridge or spanner 204 includes a pair of elongated header members 208 which are spaced apart. Each member 208 is constructed from 2 X 6 wood lumber and has an actual size of l-% inches X 5-% inches X 5 feet 2-% inches. A top plate 210 is mounted on the header members 208, with the right end portion 212 overhanging a distance of three-fourth inch whereby the end portion 212 is adapted to rest upon the top surface of stud 94 of the right wall frame 38. The top plate 210 is made of 2 X 4 wood lumber, having an actual size of linches X 3-% inches X 4 feet. The left end portions 212 of header members 208 are not covered by the top plate 210 and are adapted to fit'under the overhanging portion 206 of top plate 98 of the left wall frame 28 and to be secured thereto.

The lower spanner device 205 is made from 2 X 4 lumber and has an actual size of 1-% inches X 3- %inches X 4 feet. The right end portion of the lower spanner device 205 abuts the lower surface of the vertical stud 94 of the right wall frame 38. The end portion 206 of the lower plate 96 of the left wall frame 38 is adapted to abut the end surface of the lower spanner 205 and is secured or connected thereto by various types of fastening or connecting devices or braces, not shown.
