Definitions
- a prefabricated building erected with prefabricated wall members constructed with a framework of horizontal and vertical members and panel skins disposed at opposite sides of the framework and fixedly secured thereto.
- the outer surfaces of the framework members are provided with grooves in which are received the tongue parts of resilient strip members, the resilient strip members providing seals at the joints along which the respective edges of the wall members are secured to the building structure and to other wall members.
- the resilient strip members also serve as connecting means at the vertical seam between two adjacent wall members for connecting the wall members together without recourse to use of fastener means which extend through the vertical side edges of the wall members.
- the present invention is concerned with prefabricated building construction characterized by the facility with which a building structure can be erected and if need be later dismantled for removal to a new building site. It is also concerned with special forms of structural components for use in such buildings designed so as to reduce the cost, labor and time required for erecting and dismantling prefabricated structures.
- factory fabrication of structure components provides for optimum processing control thereby insuring production of uniform, high-quality components.
- Prefabricated structures moreover, allow for substantial standardization of components and maximum utilization of unskilled labor in the erection of the structures at the job site.
- prefabricated structure designs and components for use therein are known in the art. However, such prefabricated structure designs and components do not completely fulfill present day requirements for cost reduction and speed of prefabrication and erection.
- the wall sections thereof generally utilize connector means such as nuts and bolts, special clamps, weldments, splines, etc., at vertical seams for connecting each wall section to those wall sections adjacent therewith.
- Such connector means frequently are cumbersome to install. Also they are of ice essentially permanent character, and therefore make it very difficult, if not impossible, to dismantle the structure if it is sought to alter the same or to remove it to another building site without effecting damage to the various building components and especially prefabricated wall members.
- a further shortcoming of most known types of prefabricated structures is the lack of flexibility of the components and design thereof when it is proposed to modify a structure or depart from an existing layout. For example, if a number of pre-fabricated type one or twofamily dwellings of standardized design are being erected in a building project, such structures generally have to be built with careful adherence to the basic design leaving little margin for modifying a selected designto suit a particular purchasers preferences, of future needs, such as adding rooms, increasing overall floor space area, relocating specific rooms and the like. Unless the basic structure design and components thereof are both easily erected and dismantled, modification in or departure from the standard design is unlikely.
- the present invention is concerned with prefabricated building construction. It is concerned particularly with providing a novel prefabricated structure, prefabricated structure components, component connecting devices and erection techniques which make possible greatly reduced building costs by reducing the skilled labor required for erecting the structure, reducing the fabrication costs for building the various components in a factory on mass production scale wtih high degree of manufacturing quality, simplifying field erection of the structure with unskilled labor, and involving utilization of readily demountable components to provide flexibility for later structure alteration, repair or dismantling and removal to another building site without causing damage to the structure components.
- a prefabricated building can be field erected with components made according to the present invention with but a minimum resort to use of known components such as hardware and the like.
- a major component provided by the present invention is a prefabricated wall member which functions with a number of like wall members to establish and define the building walls.
- Such wall member is designed to be suitably used as both an exterior and interior structural component, although the gauges and sizes of materials used in the wall member may differ to the extent that for exterior wall structure heavier, more durable, elements may be employed than those used for interior wall structure.
- the wall member is designed as a structurally, self-contained unit having load-bearing capabilities thus permitting its use in supporting roof and ceiling loads.
- the wall member is designed to be compatible for use, if necessary, with the usual and known forms of building components such as windows, door frames and the like.
- the wall member can be comprised of a framework of generally rectangular configuration, such rectangular shape being provided by parallel spaced upper and lower horizontal frame members and vertical members extending between the ends of the horizontal members provided in the manner of wall studding in conventional construction.
- panel skins Secured to the framework at the opposite sides in covering position thereon are panel skins which can be provided in suitable sheet material form, e.g., plywood, plasterboard, fiberboard, asbestos board, sheet metal and the like.
- the panel skins can vary in thickness to a considerable degree and the two skins associated with each panel can differ from each other with respect to the building weather and interior side skins.
- the panel skins are each generally co-extensive with the framework
- the framework horizontal and vertical members are provided at their outer surfaces, i.e., the sides of the members defining the perimeter of the framework, with slots or grooves along a course extending end-to-end of the respective framework members.
- the grooves are provided in the framework member in conjunction with the manner in which the wall members are joined or connected to adjacent wall members and other supporting structure such as overhead beams or plates, floors, doors and the like.
- the present invention employs as an important component, strips of resilient material, the strips being relatively thin elements provided at one or both sides thereof with projecting tongue parts.
- the resilient strips function as a means for effecting the connection of the wall members to the building supporting structure.
- the grooves in the wall member framework serve to receive a projecting tongue part of the resilient strips with the strips being interposed between the framework members and the building supporting structure.
- These resilient strips are used for placement intermediate adjacent wall members and such tongue parts are received in the grooves of the vertical framework members at the adjacent ends of such wall members.
- the other supporting surfaces of the building structure to which the wall members are connected such as beams, floors and the like also can be provided with slots or grooves for receiving a strip tongue part although this is not essential.
- the resilient strip serves, as will appear in more detail later, a number of other purposes. It functions to establish a weatherproof joint between the wall member and the associated supporting surfaces.
- the strip Due to its resilient character, the strip provides a dampening means to absorb vibrations in the building structure thereby reducing noise; it functions as a locator means to insure proper wall alignment; and it also serves to compensate for expansion and contraction of the various building structure components.
- Other components provided by the invention include brackets for providing corner connection between walls, door and door-frame components, etc.
- FIG. 1 is a perspective view of a prefabricated wall member or building panel made in accordance with the present invention, portions of the wall member panel skin nearest the viewer (weather side skin) being broken away for purposes of clarity, there being depicted in exploded view the resilient strip, saddle bracket and building structure floor slab on which the wall member is supported.
- FIG. 2 is a horizontal sectional view illustrating the manner in which a building exterior wall section is erected using components made according to the present invention, there being illustrated also the manner in 4 which the exterior wall sections are joined at building corners as well as the manner in which one form of door and door frame are installed.
- FIG. 3 is a horizontal sectional view illustrating the manner in which building interior Wall sections are arranged showing particularly the manner of connecting one wall member of a wall section to the side of another wall section for space subdivision as well as the manner of capping or blanking off the terminal end of an interior partition wall.
- FIG. 4 is a fragmentary vertical sectional view illustrating the manner an exterior wall section wall member is supported on and connected to a saddle bracket connected to a building foundation or grade level slab.
- FIG. 5 is a vertical sectional view illustrating the manner in which wall members are connected to the building floor and overhead structure, the depicted wall member being one forming part of an interior wall section and being connected to a wood floor at the bottom and an overhead or ceiling support at the top.
- FIG, 6 is a sectional view of one form of resilient strip used for connecting the panel member to various building structures wherein the strip is provided with tongue parts on both sides thereof, the tongue parts being adapted to engage respectively in one of the wall member framework slots and a slotted course in the building supporting structure associated therewith and to which the wall member is connected.
- FIG. 7 is a sectional view of a modified form of resilient strip provided at one side with a tongue part for reception in the wall member, the other side of the strip being a smooth surface for abutment reception against a smooth surface of the supporting surface to which the wall member is being connected, for example, an interior building floor surface.
- the present invention provides a novel prefabricated building structure as well as the components used for erecting such structure.
- the various components are characterized by the simplicity of their construction as well as the ease and facility with which they are assembled, thereby contributing to the rapid and relatively inexpensive erection of the building structure,
- the prefabricated building of the present invention is particularly suitable for erection on mass production scale of one and twofamily dwellings, especially such dwellings as are intended to combine excellence of quality with reasonableness of purchase price.
- a most important feature of the present invention is that buildings made in accordance therewith can be dismantled at the site of original construction and removed to a new building site for erection thereon without recourse to damaging any components of the structure or rendering them unsatisfactory for reuse.
- FIG. 1 there is illustrated a prefabricated wall member or panel 10 utilized for the purpose of erecting wall structure portions of the building and which member is one of the basic important forms of structure component provided by the present invention.
- the constructional features of the wall member whether such be embodied in a wall member for exterior wall service or interior wall service, are the same with the exception that the thickness and types of sheet material used for the after-described wall member panel skins may differ from those used on the interior wall member.
- the wall member of the soon-to-be-given description is suitable for use on first, second or even third floor levels of a building structure.
- the depicted wall member 10 is representative of the various forms of such members which can be made according to the invention, the illustrated embodiment being a panel 8 feet high and 4 feet long. It will be understood that the wall member can be made in a wide range of dimensions to suit particular requirements. For example, wall members 7 feet high and 12 feet long could be utilized for special dwelling type structure applications and of course larger dimensioned wall members could be fabricated and used for commercial and/ or industrial applications.
- the wall member comprises a rugged framework of parallel-arranged, horizontally disposed upper and lower members 12, 14 respectively, and vertical members 16, 17 extending between the ends of the horizontal members 12, 14.
- the framework is fabricated conveniently with conventional 2" x 3" or 2" x 4" wood lengths although as those skilled in the art will appreciate other structural forms inclusive of specially-shaped metal members could also be used.
- the framework also can include additional vertical members or studs 18 spaced intermediate and generally parallel with the vertical members 16, 17.
- the vertical framework members 16, 17 as well as the studs 18 can be arranged in any selected pattern of spacing, as, for example, a centerline spacing of sixteen (16) inches such spacing being typical of that required by many governmental building codes. Of course, any other number of intermediate vertical members or studs 18 as desired or required could be used.
- the wall member framework is formed as a rigid structure, and for this purpose the horizontal members 12, 14 and vertical members 16, 17 and 18 are fixedly connected together in such manner as to provide with the after-described panel skins, a fully self-contained load-bearing structure capable of supporting roof, ceiling, wind and such other types of loading as can be expected to act on the structure when erected and in use.
- the above described framework members advantageously can be connected together in various ways. 'For example, a layer of an adhesive can be applied to the meeting surfaces of the various members in conjunction with the use of mechanical fastening devices such as nails, screws and the like to hold the members securely in permanent connection.
- the wall member 10 also includes as elements thereof and received on the framework in covering positions thereon at opposite sides, panel sheets or skins 20, 22 which are substantially coextensive with the expanse of the framework.
- the panel skins 20, 22 can be provided in the form of sheet material of various description, e.g., as sheets of plywood, plasterboard, Masonite, wood facing material, metal, composition materials and similar sheet t qne building material.
- the weatherside skin 20 can be somewhat thicker than the interior space skin 22.
- the panel skins 20 and 22 depicted in FIG. 2 are inch and inch in thickness, respectively.
- each outer skin 20 is provided at one end edge with a projection or shoulder-like part 26, and at the other end edge with a complemental grooved part 28.
- the projection 26 or groove 28 of one wall member 10 meets in overlapped interengagement with a projection or groove of an adjacent Wall member.
- the vertical end edges of the inner panel skins 22 of wall members 10, as will be noted in FIG. 2, can be made generally flush with the perimetrical surfaces of the vertical members 16, 17 of the wall member framework.
- the outer or perimetrical surfaces of the framework members 12, 14, 16 and 17 are provided with grooves 30 along a course extending longitudinally of the respective members from end to end, such grooves being provided for the purpose of readily removably receiving tongue parts 32, 33 or 132 of resilient strip members 34 or 134 in the manner and for the purposes to be described shortly in greater detail.
- the grooves 30 may be rabbeted in the manner as shown at 39 (shown in greater detail in FIG. 2) so as to provide an enhancement of the degree of sealing engagement between the groove surfaces and the plurality of yieldably or defiectably formed wings 52 or 152 provided on the strip tongue parts 32, 33 or 132.
- a feature of the present invention is that the various wall members 10 and a-110c except at the intersection of wall sections and at door and window frames, are joined together without recourse to connection at the vertical seam juncture of each wall member 10 or 1100-1100 with a member adjacent thereto with fastener means which extend through the wall members on which involve effecting such connection with a permanent fastener member such as nails, bolts, brackets, weldments and so on.
- the present invention provides that such joinder or connection of adjacent wall members can be achieved with means that are easily removably received in the wall members 10 and 110a110c, yet such means provide a degree of wall members securement that precludes wall member deflection or loss of alignment under the heaviest loading to which the wall may be subjected.
- the resilient strips 34, 134 employed in making connection of the wall members to other Wall members and also to supporting structure in the building.
- the resilient strips can be made in various forms depending on the particular use and location of a strip in the structure.
- the strip 34 illustrated in FIG. 6 is intended for use at the vertical seams between adjacent wall members and for connection of top of the Wall members with overhead supporting building structure such as a plate, beam and the like.
- the strip 34 is comprised of an elongated relatively thin body 50 of flexible or resilient material such as neoprene.
- the overall length of the resilient strips conveniently is determined by the length of the wall structure with which they are used and they can be provided in a single length coextensive with the vertical edges of each wall member, the full horizontal length of a wall section or in such number of individual sections as may be required to meet the particular installation requirement.
- the strips can have an overall length of about 8 feet, whereas the horizontal runs below each wall member and at the top thereof, the strips may have a length from 4 feet upwards to the full wall section length.
- the strip 34 generally has a width substantially equal to the thickness or slightly less than the thickness of the wall member with which it is used.
- tongue parts 32 and 33 Formed integrally with the thin strip body 50, and extending centrally therein and outwardly from the body at opposite sides thereof are relatively non-readily deformable, thick tongue parts 32 and 33. Both tongue parts 32, 33 are of such dimension as to make them relatively rigid in contrast with the easily defiectable body part 50. Thus, the tongue parts 32, 33 are provided with a certain strength to resist loading force applied to the wall members in the manner to be described more fully later on to maintain the wall members in proper alignment and positioning in the building structure. Each tongue part 32, 33 is provided at its sides with a plurality of yieldable or readily deformable wings 52.
- the wings 52 which are formed integrally with the tongue parts, constitute yieldable elements adapted for efiecting close engagement with the grooves 30 formed in the framework of the wall members 10, 110a-110c to assure tight engagement between these elements. Further, the wings 52 facilitate the readily removable reception of the tongue parts in the grooves 30 of the wall member framework as well as in grooves formed in the associated supporting structure of the building to which the wall member is secured. For example, as may be noted in FIG. 1, a resilient strip 34 is received on top of the frame member 12 with its tongue part 33 received in the groove 30 of such frame member.
- the other tongue part 32 is intended for reception in the building overhead structure associated with and providing securement for the wall member and which by way of example is depicted in FIG.
- the resilient strip 34 is so constructed that the connection made herewith, particularly at vertical seams of adjacent wall members, prohibits any relative movement between such wall members. This is in part due to the nature of the material of which the resilient strip is made as well as the relatively thick body of the tongue part. While the wings 52 are defiectable, the tongue parts 32, 33 being relatively thick resist forces applied against the wall member whether the forces be a vertical loading or a loading applied against the face of the wall member, thereby insuring the positioning of the wall member and structural integrity of the building.
- the resilient strip 34 as indicated earlier generally has a main body 50 of overall width about the same dimension as or slightly less than the thickness of the wall member and a body thickness of about A; inch.
- the overall height of the tongue parts 32, 33 can vary depending on the size of the supporting structure and wall member frame with which they are used. However, for most applications the height of the tongue parts from base end, i.e., point of juncture with body 50, to tip end will be about A; to A of an inch, and a main body thickness or lateral expanse excluding the wings, of about A; to /2 inch. Depending on the rigidity of the basic material selected, these dimensions may, of course, vary.
- the resilient strips 34, 134 as can be best noted in FIG.
- elongated openings 40 in the main body part 50 are provided with a number of elongated openings 40 in the main body part 50 arranged alternately at opposite sides of the tongue parts, such elongated openings being provided to permit passage through the resilient strips of the nuts and bolts with which the upper part of the wall members and the lower part thereof are secured to the associated buildi'ng supporting structure in the manner to be described ater.
- FIG. 7 depicts a modified form of resilient strip 132 which is in all respects the same as the strip just described, except it is provided with only one tongue part 132, it being understood that the remaining portions of the strip designated by corresponding reference numerals one hundred numbers higher, are the same as those of the strip 34.
- the resilient strip 134 is intended for use in connecting the bottom of the wall members to a supporting surface such as a floor, a special supporting saddle on a building foundation, and also for connecting the vertical edge of a wall member to another where the former is part of one wall section intersecting with the latter and the latter is part of another wall section.
- the strip 134 is employed where it is not convenient or possible to provide a groove or slot in a wall member face or in a floor or foundation saddle.
- Both the resilient strip 34 and the resilient strip 134 may be provided with split side edges, such side edges being split into two branches as at 56, 58 and 156, 158 respectively, the branches providing for reception of building finish and trim components as will be described in greater detail later on.
- the present invention provides that fastening means which pass through the wall members are employed only at the tops and bottom of the wall members and at the intersections of wall sections wherein exterior wall members are concerned.
- Wall members used at the inside of a building may involve use of such fastening means only at the top thereof.
- nuts 60' and bolts 62 are preferred.
- the top and bottom frame members 12 and 14 are provided with a number of bored openings 42, such openings being provided at spaced-apart alternately olf-center locations as shown in FIG.
- the arrangement of alternately offset openings and nut and bolt positioning being made for distributing the fastening load evenly throughout the framework structure and to avoid having to pass the bolts through the relatively thick tongue-parts of the resilient strips.
- the bore openings 42 through which the bolts 62 are inserted can be countersunk as at 45 (see FIG. 4) to facilitate the workmans inserting the nut which frequently must be done blind.
- the wall members 10' and 11011-1100 are fabricated with the nuts 60 associated with the top and bottom frame members 12 and 14 preinstalled and fixed at the inner sides of such members.
- the nuts 60 are fixed to the frame member 14 with nails 46.
- the nuts 60 being preinstalled enable rapid field assembly and eliminate recourse to complicated fastening devices permitting wall member connection to associated supporting structure in the most direct and inexpensive manner and giving the latitude for easily and simply dismantling the wall members should the need arise.
- the wall members 10 and 110a-110c also can include a filler therein sandwiched between the panel skins 2.0, 22, such filler being a mass of a thermally insulative material 66, only a portion of the material being shown in FIG. 1 but it being understood that it may fill each bay of the wall member defined by the frame members 16, 17 and 18.
- a thermally insulative material 66 can be any one of the known insulators including glass fiber, asbestos, foamed plastic and the like.
- the wall members can be provided with utility components depicted illustratively by the electrical wiring 67 shown in FIG.
- FIG. 2 illustrates the manner in which an exterior Wall section and associated components including a door 70, and door frame 72 are erected in a building with the prefabricated components of the present invention. While in FIG. 2, the full length wall section is not shown, it will be understood that as many wall members 10' as are required can be employed in the exterior wall section. However, the manner of connecting such intervening Wall members is the same as that now to be described, continuing reference being made to FIGS. 1, 2 and 4.
- the respective wall members 10 used for exterior walls are designed to be supported directly on a floor slab, foundation, upper level plate or the like. In one representative form of structure erection, the exterior walls are received on support saddles designed for connection to a building foundation 82.
- the saddle 80' can include a vertical leg 84 which is secured to the foundation 82 by means of anchor bolts 86, the foundation having female bolt receiving fitting 88 cast therein which fitting houses the nuts 90 used in conjunction with the anchor bolts 86.
- the saddles 80' also include a horizontal leg 92 on which physical placement of the resilient strips 134 and wall members occur. As shown in FIG. 1, the horizontal leg 92 is provided with elongated slotted openings 94 for receiving the nuts 62 with which the wall member 10 is secured at its bottom to the supporting surface.
- the installation of the saddles 80 to the foundation 82' is effected in such manner as to present a level horizontal disposition to the leg 92 of the saddle thereby insuring proper level alignment of the wall structure.
- the respective exterior wall members are then received on the saddle with a resilient strip 134 intervening the lower horizontal frame member 14- of each wall member and the upper surface of the saddle leg 92.
- the tongue parts 132 of the resilient strips are received in the grooves 30 of the lower frame members 14 of the various wall members 10.
- Fasteners such as bolts 62 are then passed through saddle leg 92, resilient strip 134 and bottom frame member 14- of each wall member 10 from the underside of the saddle in the manner depicted in FIG. 4, the bolts being threaded into the pre-installed nuts 60 on the upper surface of the lower frame member 14 and secured thereto against rotation about its own axis with nails 46.
- the remaining exterior wall members 10 are of course installed on the foundation 82 in the same manner.
- a resilient strip 34 is first inserted over the vertical end framework member 17 of the installed wall member with one tongue part 32 received in the associated groove 30 of the framework member of such installed wall member.
- the other tongue part 33 is then positioned to be received in the groove 30 of the vertical member 16 of the wall member 10 to be installed next.
- fastener means are utilized which extend through the ends of the wall members 10 forming the corner joint.
- Such joint is provided as shown in FIG. 2 by employing a bracket 160 having at least two legs 161, 162 joined with a central part 163 and to which are connected the vertical edges of the respective intersecting wall members 10.
- the bracket is provided as an element having a vertical height corresponding with that of the wall members 10 and the respective legs 161, 162 thereof are connected to the vertical frame members 17, 16 of the two wall members with nuts 164 and bolts 166 in the same manner as described earlier in connection with the nuts 62 and bolts 60 with which securement of the wall members 10 is made to the foundation saddles 80, the nuts 164 and bolts 166 being alternately offset from the vertical centerline of the frame members 17, 16 and the nuts 164 being preinstalled on the frame members in the same manner as the nuts 62.
- the inner vertical surfaces of frame members 17, 16 are provided with nuts 164 fixed thereto at vertically spaced intervals and the bolts 166 received therein pass through the resilient strips 134 at such intervals.
- the break at the corner joint is finished to present a flush surface with the outer surface of the wall members 10 with facing strips 170, the latter being toe-nailed into the panel skins in the manner illustrated as at 172.
- a feature of the present invention is that the wall members 10, 110a-110c are easily adapted for embodiment of doors and windows in a structure made therewith. Standard manufactured windows and doors could be used or these components can be especially designed for incorporation in the structure of the wall members.
- FIG. 2 illustrates one manner in which a door can be installed in an exterior wall section.
- two door frame elements or battens 72 can be installed at the opposed ends of two wall members 10 defining a space in the wall section.
- Such space could, for example, be a 4-foot space produced by omitting a wall member in the Wall section.
- Such frame members 72 are intervened in their connection to the wall members 10 by means of resilient strips 134 in the same manner as previously described in connection with the corner joint.
- the frame members 72 are connected to the wall members 10 with nuts 164 and bolts 166 at a number of vertical-spaced locations in the same manner as described for the corner joint, and door stop strips 170 are received in slots 172 provided in the frame members 72.
- the door 70 is hinged as at 174 to one frame member 72 and a dead bolt leaf or false door 176 which also provides the door stop 178 can be secured to the other frame member 72.
- a regular sized door opening is provided for entry from the exterior to the building interior and if necessary, the false door 176 can be removed to provide an opening of almost 4 feet for maximum access when moving furniture, etc.
- the external or weather wall surfaces are made water tight by means of the projection and groove arrangement as depicted at 26 and 28, the overlapping joint being such as to provide with the resilient strip 34 a substantially water-tight seam.
- the manner of closing off entry to a vertical seam at the weather side adjacent the door is effected by means of a decorative trim strip 180', which has a projecting finger 182 which is received in the vertical seam between the end parts 56, 58 of the resilient strip 34.
- a trim piece 184 can be snapped into the branches of the resilient strip 134 at the corner joint.
- Wall joints at the inside of the wall section can be finished with trim pieces received in end parts 56, 58 of the resilient strip 134, with removable tape or any other manner satisfactory to the purpose.
- FIGS. 3 and 5 illustrate the manner of installation of interior wall members 110a-110c.
- the interior wall members can be installed easily and quickly in several ways involving minimum use of fasteners such as nuts and bolts except at the tops of the wall members or at the ends of a partition section.
- an interior wall section subdividing a space and intersecting another wall section can be easily installed by first fixing a resilient strip 134 (FIG. 3) to the skin 122 of one wall member 110a, the strip 134 being secured on skin 122 with nails 202, adhesive or other fastening means, the strip installation being effected such that the longitudinal direction of the tongue part 132 extends perpendicular to the floor surface.
- a second resilient strip 134 is then laid on the floor 204 (FIG.
- the wall member mounted and floor mounted resilient strips provide locator means to insure that the interior wall member 1101) can be installed with proper alignment to wall member 110a without leveling, measuring, etc.
- the wall member 11% is then set in place with the groove 30 in frame member 117 receiving the tongue part 132 of the wall mounted strip 134 (FIG. 3) and the groove 30 in frame member 114 receiving the tongue part 132 in the floor mounted strip 134 (FIG. 5).
- FIG. 5 shows the manner in which the upper or top parts of interior wall sections are secured to associated building supporting surfaces.
- the panel skins may each be of the same thickness and composition since not being exposed to the elements such panel skins can be of a lighter gauge.
- the bottom part of the interior wall member 1101) is secured to the floor slab or other floor structure 204 by being supported solely through the agency of the resilient strip 134.
- suitable connection can be provided by bolting through the upper horizontal frame member 112 of the wall member 11% to an overhead structure such as a cross beam connected to the bottom chord of a truss.

The outer surfaces of the framework members are provided with grooves in which are received the tongue parts of resilient strip members, the resilient strip members providing seals at the joints along which the respective edges of the wall members are secured to the building structure and to other wall members. The resilient strip members also serve as connecting means at the vertical seam between two adjacent wall members for connecting the wall members together without recourse to use of fastener means which extend through the vertical side edges of the wall members.
BACKGROUND OF THE INVENTION The present invention is concerned with prefabricated building construction characterized by the facility with which a building structure can be erected and if need be later dismantled for removal to a new building site. It is also concerned with special forms of structural components for use in such buildings designed so as to reduce the cost, labor and time required for erecting and dismantling prefabricated structures.
It is becoming more commonplace to use prefabricated building construction components and techniques in meeting the needs of housing construction, particularly to offset the very high labor costs attending erection of dwellings with conventional building materials and techniques. The advantages of providing prefabricated structures to meet building needs are well known, particularly with respect to the reduction of labor costs as well as the speed with which such structures can be erected and placed in service. Not only are consequential savings realized with respect to erection labor costs when using prefabricated construction, but the costs of fabricating the prefabricated structure components also can be reduced in that the major portion of fabrication is done in a factory on a mass production basis providing for the economic advantages attending large quantity material purchases, mass production fabrication techniques and more effective utilization of labor. Additionally, factory fabrication of structure components provides for optimum processing control thereby insuring production of uniform, high-quality components. Prefabricated structures, moreover, allow for substantial standardization of components and maximum utilization of unskilled labor in the erection of the structures at the job site.
Many forms of prefabricated structure designs and components for use therein are known in the art. However, such prefabricated structure designs and components do not completely fulfill present day requirements for cost reduction and speed of prefabrication and erection. .For example, in prior art prefabricated structures, the wall sections thereof generally utilize connector means such as nuts and bolts, special clamps, weldments, splines, etc., at vertical seams for connecting each wall section to those wall sections adjacent therewith. Such connector means frequently are cumbersome to install. Also they are of ice essentially permanent character, and therefore make it very difficult, if not impossible, to dismantle the structure if it is sought to alter the same or to remove it to another building site without effecting damage to the various building components and especially prefabricated wall members. Further, in making installation with prior art wall sections, whether for exterior or interior walls, skilled workmen, e.g., carpenters, are usually required to superintend the physical placement of each section to ensure that proper wall alignment is established and maintained during the course of the erection of the structure. Furthermore, in prefabricated structure types as are known, it is difficult to weatherproof, soundproof and control expansion and contraction in the structure except by the use of complicated and expensive joint and sealing devices. Thus, incorporation of complicated and special devices in a prefabricated structure as well as need to employ skilled labor in the erection thereof, constitute factors which make it difficult to reduce building construction cost especially wherein it is sought to erect an attractive, durable quality-type dwelling.
A further shortcoming of most known types of prefabricated structures is the lack of flexibility of the components and design thereof when it is proposed to modify a structure or depart from an existing layout. For example, if a number of pre-fabricated type one or twofamily dwellings of standardized design are being erected in a building project, such structures generally have to be built with careful adherence to the basic design leaving little margin for modifying a selected designto suit a particular purchasers preferences, of future needs, such as adding rooms, increasing overall floor space area, relocating specific rooms and the like. Unless the basic structure design and components thereof are both easily erected and dismantled, modification in or departure from the standard design is unlikely.
SUMMARY OF THE PRESENT INVENTION The present invention is concerned with prefabricated building construction. It is concerned particularly with providing a novel prefabricated structure, prefabricated structure components, component connecting devices and erection techniques which make possible greatly reduced building costs by reducing the skilled labor required for erecting the structure, reducing the fabrication costs for building the various components in a factory on mass production scale wtih high degree of manufacturing quality, simplifying field erection of the structure with unskilled labor, and involving utilization of readily demountable components to provide flexibility for later structure alteration, repair or dismantling and removal to another building site without causing damage to the structure components.
In accordance with the present invention, a prefabricated building can be field erected with components made according to the present invention with but a minimum resort to use of known components such as hardware and the like. A major component provided by the present invention is a prefabricated wall member which functions with a number of like wall members to establish and define the building walls. Such wall member is designed to be suitably used as both an exterior and interior structural component, although the gauges and sizes of materials used in the wall member may differ to the extent that for exterior wall structure heavier, more durable, elements may be employed than those used for interior wall structure. The wall member is designed as a structurally, self-contained unit having load-bearing capabilities thus permitting its use in supporting roof and ceiling loads. Moreover, the wall member is designed to be compatible for use, if necessary, with the usual and known forms of building components such as windows, door frames and the like. In one form of construction, the wall member can be comprised of a framework of generally rectangular configuration, such rectangular shape being provided by parallel spaced upper and lower horizontal frame members and vertical members extending between the ends of the horizontal members provided in the manner of wall studding in conventional construction. Secured to the framework at the opposite sides in covering position thereon are panel skins which can be provided in suitable sheet material form, e.g., plywood, plasterboard, fiberboard, asbestos board, sheet metal and the like. The panel skins can vary in thickness to a considerable degree and the two skins associated with each panel can differ from each other with respect to the building weather and interior side skins. However, the panel skins are each generally co-extensive with the framework, The framework horizontal and vertical members are provided at their outer surfaces, i.e., the sides of the members defining the perimeter of the framework, with slots or grooves along a course extending end-to-end of the respective framework members. The grooves are provided in the framework member in conjunction with the manner in which the wall members are joined or connected to adjacent wall members and other supporting structure such as overhead beams or plates, floors, doors and the like. For such purpose, the present invention employs as an important component, strips of resilient material, the strips being relatively thin elements provided at one or both sides thereof with projecting tongue parts. The resilient strips function as a means for effecting the connection of the wall members to the building supporting structure. The grooves in the wall member framework serve to receive a projecting tongue part of the resilient strips with the strips being interposed between the framework members and the building supporting structure. These resilient strips are used for placement intermediate adjacent wall members and such tongue parts are received in the grooves of the vertical framework members at the adjacent ends of such wall members. The other supporting surfaces of the building structure to which the wall members are connected such as beams, floors and the like also can be provided with slots or grooves for receiving a strip tongue part although this is not essential. In addition to serving as a sturdy connector means, the resilient strip serves, as will appear in more detail later, a number of other purposes. It functions to establish a weatherproof joint between the wall member and the associated supporting surfaces. Due to its resilient character, the strip provides a dampening means to absorb vibrations in the building structure thereby reducing noise; it functions as a locator means to insure proper wall alignment; and it also serves to compensate for expansion and contraction of the various building structure components. Other components provided by the invention include brackets for providing corner connection between walls, door and door-frame components, etc.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides a novel prefabricated building structure as well as the components used for erecting such structure. The various components are characterized by the simplicity of their construction as well as the ease and facility with which they are assembled, thereby contributing to the rapid and relatively inexpensive erection of the building structure, The prefabricated building of the present invention is particularly suitable for erection on mass production scale of one and twofamily dwellings, especially such dwellings as are intended to combine excellence of quality with reasonableness of purchase price. A most important feature of the present invention is that buildings made in accordance therewith can be dismantled at the site of original construction and removed to a new building site for erection thereon without recourse to damaging any components of the structure or rendering them unsatisfactory for reuse.
Referring now to FIG. 1, there is illustrated a prefabricated wall member or panel 10 utilized for the purpose of erecting wall structure portions of the building and which member is one of the basic important forms of structure component provided by the present invention. The constructional features of the wall member whether such be embodied in a wall member for exterior wall service or interior wall service, are the same with the exception that the thickness and types of sheet material used for the after-described wall member panel skins may differ from those used on the interior wall member. Moreover, the wall member of the soon-to-be-given description is suitable for use on first, second or even third floor levels of a building structure. The depicted wall member 10 is representative of the various forms of such members which can be made according to the invention, the illustrated embodiment being a panel 8 feet high and 4 feet long. It will be understood that the wall member can be made in a wide range of dimensions to suit particular requirements. For example, wall members 7 feet high and 12 feet long could be utilized for special dwelling type structure applications and of course larger dimensioned wall members could be fabricated and used for commercial and/ or industrial applications. The wall member comprises a rugged framework of parallel-arranged, horizontally disposed upper and lower members 12, 14 respectively, and vertical members 16, 17 extending between the ends of the horizontal members 12, 14. If the Wall member is intended for prefabricated dwelling structure use, the framework is fabricated conveniently with conventional 2" x 3" or 2" x 4" wood lengths although as those skilled in the art will appreciate other structural forms inclusive of specially-shaped metal members could also be used. The framework also can include additional vertical members or studs 18 spaced intermediate and generally parallel with the vertical members 16, 17. The vertical framework members 16, 17 as well as the studs 18 can be arranged in any selected pattern of spacing, as, for example, a centerline spacing of sixteen (16) inches such spacing being typical of that required by many governmental building codes. Of course, any other number of intermediate vertical members or studs 18 as desired or required could be used. The wall member framework is formed as a rigid structure, and for this purpose the horizontal members 12, 14 and vertical members 16, 17 and 18 are fixedly connected together in such manner as to provide with the after-described panel skins, a fully self-contained load-bearing structure capable of supporting roof, ceiling, wind and such other types of loading as can be expected to act on the structure when erected and in use. The above described framework members advantageously can be connected together in various ways. 'For example, a layer of an adhesive can be applied to the meeting surfaces of the various members in conjunction with the use of mechanical fastening devices such as nails, screws and the like to hold the members securely in permanent connection. The wall member 10 also includes as elements thereof and received on the framework in covering positions thereon at opposite sides, panel sheets or skins 20, 22 which are substantially coextensive with the expanse of the framework. The panel skins 20, 22 can be provided in the form of sheet material of various description, e.g., as sheets of plywood, plasterboard, Masonite, wood facing material, metal, composition materials and similar sheet t qne building material. As will be noted in FIG. 2, and with respect to wall members 10 designed to provide building exterior wall sections, the weatherside skin 20 can be somewhat thicker than the interior space skin 22. The panel skins 20 and 22 depicted in FIG. 2 are inch and inch in thickness, respectively. Since building structure interior wall sections are not exposed to the degree of wear and tear and loading of exterior walls, the panel skins 120, 122 for wall members 110a-110c embodied in interior wall sections such as shown in FIG. 3 can be of lighter gauge material than those used in the exterior wall section wall members 10. In the case of the weatherside skins 20, the vertical edges thereof can be so formed such as to provide a substantially watertight joint in conjunction with the outer skins 20 of the wall members adjacent thereto. Thus, each outer skin 20 is provided at one end edge with a projection or shoulder-like part 26, and at the other end edge with a complemental grooved part 28. Thus, when arranged in connected alignment with adjacent wall members, the projection 26 or groove 28 of one wall member 10 meets in overlapped interengagement with a projection or groove of an adjacent Wall member. The vertical end edges of the inner panel skins 22 of wall members 10, as will be noted in FIG. 2, can be made generally flush with the perimetrical surfaces of the vertical members 16, 17 of the wall member framework.
The outer or perimetrical surfaces of the framework members 12, 14, 16 and 17 are provided with grooves 30 along a course extending longitudinally of the respective members from end to end, such grooves being provided for the purpose of readily removably receiving tongue parts 32, 33 or 132 of resilient strip members 34 or 134 in the manner and for the purposes to be described shortly in greater detail. The grooves 30 may be rabbeted in the manner as shown at 39 (shown in greater detail in FIG. 2) so as to provide an enhancement of the degree of sealing engagement between the groove surfaces and the plurality of yieldably or defiectably formed wings 52 or 152 provided on the strip tongue parts 32, 33 or 132.
As indicated before, a feature of the present invention is that the various wall members 10 and a-110c except at the intersection of wall sections and at door and window frames, are joined together without recourse to connection at the vertical seam juncture of each wall member 10 or 1100-1100 with a member adjacent thereto with fastener means which extend through the wall members on which involve effecting such connection with a permanent fastener member such as nails, bolts, brackets, weldments and so on. The present invention provides that such joinder or connection of adjacent wall members can be achieved with means that are easily removably received in the wall members 10 and 110a110c, yet such means provide a degree of wall members securement that precludes wall member deflection or loss of alignment under the heaviest loading to which the wall may be subjected.
Before continuing with the description of the wall members 10 and 110a-110c, consideration will be directed to the construction and function of an important component provided by the present invention for use in conjunction with said wall members, viz, the resilient strips 34, 134 employed in making connection of the wall members to other Wall members and also to supporting structure in the building. The resilient strips can be made in various forms depending on the particular use and location of a strip in the structure. The strip 34 illustrated in FIG. 6 is intended for use at the vertical seams between adjacent wall members and for connection of top of the Wall members with overhead supporting building structure such as a plate, beam and the like. The strip 34 is comprised of an elongated relatively thin body 50 of flexible or resilient material such as neoprene. The overall length of the resilient strips conveniently is determined by the length of the wall structure with which they are used and they can be provided in a single length coextensive with the vertical edges of each wall member, the full horizontal length of a wall section or in such number of individual sections as may be required to meet the particular installation requirement. For example, for use at vertical seams between adjacent wall members the strips can have an overall length of about 8 feet, whereas the horizontal runs below each wall member and at the top thereof, the strips may have a length from 4 feet upwards to the full wall section length. The strip 34 generally has a width substantially equal to the thickness or slightly less than the thickness of the wall member with which it is used. Formed integrally with the thin strip body 50, and extending centrally therein and outwardly from the body at opposite sides thereof are relatively non-readily deformable, thick tongue parts 32 and 33. Both tongue parts 32, 33 are of such dimension as to make them relatively rigid in contrast with the easily defiectable body part 50. Thus, the tongue parts 32, 33 are provided with a certain strength to resist loading force applied to the wall members in the manner to be described more fully later on to maintain the wall members in proper alignment and positioning in the building structure. Each tongue part 32, 33 is provided at its sides with a plurality of yieldable or readily deformable wings 52. The wings 52 which are formed integrally with the tongue parts, constitute yieldable elements adapted for efiecting close engagement with the grooves 30 formed in the framework of the wall members 10, 110a-110c to assure tight engagement between these elements. Further, the wings 52 facilitate the readily removable reception of the tongue parts in the grooves 30 of the wall member framework as well as in grooves formed in the associated supporting structure of the building to which the wall member is secured. For example, as may be noted in FIG. 1, a resilient strip 34 is received on top of the frame member 12 with its tongue part 33 received in the groove 30 of such frame member. On the other hand, the other tongue part 32 is intended for reception in the building overhead structure associated with and providing securement for the wall member and which by way of example is depicted in FIG. 1 as being a plate 36, such plate being provided with a groove 37 similar to that in frame member 12. The resilient strip 34 is so constructed that the connection made herewith, particularly at vertical seams of adjacent wall members, prohibits any relative movement between such wall members. This is in part due to the nature of the material of which the resilient strip is made as well as the relatively thick body of the tongue part. While the wings 52 are defiectable, the tongue parts 32, 33 being relatively thick resist forces applied against the wall member whether the forces be a vertical loading or a loading applied against the face of the wall member, thereby insuring the positioning of the wall member and structural integrity of the building. The resilient strip 34 as indicated earlier generally has a main body 50 of overall width about the same dimension as or slightly less than the thickness of the wall member and a body thickness of about A; inch. The overall height of the tongue parts 32, 33 can vary depending on the size of the supporting structure and wall member frame with which they are used. However, for most applications the height of the tongue parts from base end, i.e., point of juncture with body 50, to tip end will be about A; to A of an inch, and a main body thickness or lateral expanse excluding the wings, of about A; to /2 inch. Depending on the rigidity of the basic material selected, these dimensions may, of course, vary. The resilient strips 34, 134 as can be best noted in FIG. 1 are provided with a number of elongated openings 40 in the main body part 50 arranged alternately at opposite sides of the tongue parts, such elongated openings being provided to permit passage through the resilient strips of the nuts and bolts with which the upper part of the wall members and the lower part thereof are secured to the associated buildi'ng supporting structure in the manner to be described ater.
FIG. 7 depicts a modified form of resilient strip 132 which is in all respects the same as the strip just described, except it is provided with only one tongue part 132, it being understood that the remaining portions of the strip designated by corresponding reference numerals one hundred numbers higher, are the same as those of the strip 34. The resilient strip 134 is intended for use in connecting the bottom of the wall members to a supporting surface such as a floor, a special supporting saddle on a building foundation, and also for connecting the vertical edge of a wall member to another where the former is part of one wall section intersecting with the latter and the latter is part of another wall section. Thus it will be seen the strip 134 is employed where it is not convenient or possible to provide a groove or slot in a wall member face or in a floor or foundation saddle.
Both the resilient strip 34 and the resilient strip 134 may be provided with split side edges, such side edges being split into two branches as at 56, 58 and 156, 158 respectively, the branches providing for reception of building finish and trim components as will be described in greater detail later on.
Continuing now with further description of the wall members 10' and 110a110c, the present invention provides that fastening means which pass through the wall members are employed only at the tops and bottom of the wall members and at the intersections of wall sections wherein exterior wall members are concerned. Wall members used at the inside of a building may involve use of such fastening means only at the top thereof. Where such fastening means are employed, nuts 60' and bolts 62 are preferred. To accommodate the reception of such nut and bolt means, the top and bottom frame members 12 and 14 are provided with a number of bored openings 42, such openings being provided at spaced-apart alternately olf-center locations as shown in FIG. 1, and being adapted to register with the corresponding openings 40 formed in the resilient strips 34 and 134, the arrangement of alternately offset openings and nut and bolt positioning being made for distributing the fastening load evenly throughout the framework structure and to avoid having to pass the bolts through the relatively thick tongue-parts of the resilient strips. To facilitate wall member installation, the bore openings 42 through which the bolts 62 are inserted can be countersunk as at 45 (see FIG. 4) to facilitate the workmans inserting the nut which frequently must be done blind. Also, the wall members 10' and 11011-1100 are fabricated with the nuts 60 associated with the top and bottom frame members 12 and 14 preinstalled and fixed at the inner sides of such members. Thus, as seen in FIG. 4, the nuts 60 are fixed to the frame member 14 with nails 46. The nuts 60 being preinstalled enable rapid field assembly and eliminate recourse to complicated fastening devices permitting wall member connection to associated supporting structure in the most direct and inexpensive manner and giving the latitude for easily and simply dismantling the wall members should the need arise.
As can be seen in FIGS. 1-3, the wall members 10 and 110a-110c also can include a filler therein sandwiched between the panel skins 2.0, 22, such filler being a mass of a thermally insulative material 66, only a portion of the material being shown in FIG. 1 but it being understood that it may fill each bay of the wall member defined by the frame members 16, 17 and 18. Such material can be any one of the known insulators including glass fiber, asbestos, foamed plastic and the like. Furthermore, and in keeping with the feature of ready erection and dismantling of the wall members and structures prefabricated therefrom, the wall members can be provided with utility components depicted illustratively by the electrical wiring 67 shown in FIG. 1, such wiring being made operative in the building circuitry with suitable plug-type connectors 68, the illustrated components including a wall-mounted electrical power outlet 69. Provision for other utilities including heating, fresh-water, sanitary facilities, airconditioning, etc. also can be provided in the wall members.
FIG. 2 illustrates the manner in which an exterior Wall section and associated components including a door 70, and door frame 72 are erected in a building with the prefabricated components of the present invention. While in FIG. 2, the full length wall section is not shown, it will be understood that as many wall members 10' as are required can be employed in the exterior wall section. However, the manner of connecting such intervening Wall members is the same as that now to be described, continuing reference being made to FIGS. 1, 2 and 4. The respective wall members 10 used for exterior walls are designed to be supported directly on a floor slab, foundation, upper level plate or the like. In one representative form of structure erection, the exterior walls are received on support saddles designed for connection to a building foundation 82. The saddle 80' can include a vertical leg 84 which is secured to the foundation 82 by means of anchor bolts 86, the foundation having female bolt receiving fitting 88 cast therein which fitting houses the nuts 90 used in conjunction with the anchor bolts 86. The saddles 80' also include a horizontal leg 92 on which physical placement of the resilient strips 134 and wall members occur. As shown in FIG. 1, the horizontal leg 92 is provided with elongated slotted openings 94 for receiving the nuts 62 with which the wall member 10 is secured at its bottom to the supporting surface. The installation of the saddles 80 to the foundation 82' is effected in such manner as to present a level horizontal disposition to the leg 92 of the saddle thereby insuring proper level alignment of the wall structure. The respective exterior wall members are then received on the saddle with a resilient strip 134 intervening the lower horizontal frame member 14- of each wall member and the upper surface of the saddle leg 92. As was indicated earlier, the tongue parts 132 of the resilient strips are received in the grooves 30 of the lower frame members 14 of the various wall members 10. Fasteners such as bolts 62 are then passed through saddle leg 92, resilient strip 134 and bottom frame member 14- of each wall member 10 from the underside of the saddle in the manner depicted in FIG. 4, the bolts being threaded into the pre-installed nuts 60 on the upper surface of the lower frame member 14 and secured thereto against rotation about its own axis with nails 46. The remaining exterior wall members 10 are of course installed on the foundation 82 in the same manner. However, as a preliminary to mounting a new wall member 10 on the saddle 80- to one already installed, a resilient strip 34 is first inserted over the vertical end framework member 17 of the installed wall member with one tongue part 32 received in the associated groove 30 of the framework member of such installed wall member. The other tongue part 33 is then positioned to be received in the groove 30 of the vertical member 16 of the wall member 10 to be installed next. With the saddle 80' having been properly leveled, and with the first installed wall member properly lined up in the vertical, the resilient strips 34 thereafter serve to assure that all succeedingly installed wall members 10 are arranged in proper alignment.
As was indicated earlier, at the corners of the building structure, i.e., the intersection of two exterior wall sections, fastener means are utilized which extend through the ends of the wall members 10 forming the corner joint. Such joint is provided as shown in FIG. 2 by employing a bracket 160 having at least two legs 161, 162 joined with a central part 163 and to which are connected the vertical edges of the respective intersecting wall members 10. The bracket is provided as an element having a vertical height corresponding with that of the wall members 10 and the respective legs 161, 162 thereof are connected to the vertical frame members 17, 16 of the two wall members with nuts 164 and bolts 166 in the same manner as described earlier in connection with the nuts 62 and bolts 60 with which securement of the wall members 10 is made to the foundation saddles 80, the nuts 164 and bolts 166 being alternately offset from the vertical centerline of the frame members 17, 16 and the nuts 164 being preinstalled on the frame members in the same manner as the nuts 62. Thus, it will be noted that the inner vertical surfaces of frame members 17, 16 are provided with nuts 164 fixed thereto at vertically spaced intervals and the bolts 166 received therein pass through the resilient strips 134 at such intervals. The break at the corner joint is finished to present a flush surface with the outer surface of the wall members 10 with facing strips 170, the latter being toe-nailed into the panel skins in the manner illustrated as at 172.
A feature of the present invention is that the wall members 10, 110a-110c are easily adapted for embodiment of doors and windows in a structure made therewith. Standard manufactured windows and doors could be used or these components can be especially designed for incorporation in the structure of the wall members.
FIG. 2 illustrates one manner in which a door can be installed in an exterior wall section. For this purpose two door frame elements or battens 72 can be installed at the opposed ends of two wall members 10 defining a space in the wall section. Such space could, for example, be a 4-foot space produced by omitting a wall member in the Wall section. Such frame members 72, it will be noted, are intervened in their connection to the wall members 10 by means of resilient strips 134 in the same manner as previously described in connection with the corner joint. The frame members 72 are connected to the wall members 10 with nuts 164 and bolts 166 at a number of vertical-spaced locations in the same manner as described for the corner joint, and door stop strips 170 are received in slots 172 provided in the frame members 72. The door 70 is hinged as at 174 to one frame member 72 and a dead bolt leaf or false door 176 which also provides the door stop 178 can be secured to the other frame member 72. In this manner a regular sized door opening is provided for entry from the exterior to the building interior and if necessary, the false door 176 can be removed to provide an opening of almost 4 feet for maximum access when moving furniture, etc.
As was indicated earlier the external or weather wall surfaces are made water tight by means of the projection and groove arrangement as depicted at 26 and 28, the overlapping joint being such as to provide with the resilient strip 34 a substantially water-tight seam. On the other hand the manner of closing off entry to a vertical seam at the weather side adjacent the door is effected by means of a decorative trim strip 180', which has a projecting finger 182 which is received in the vertical seam between the end parts 56, 58 of the resilient strip 34. Similarly, a trim piece 184 can be snapped into the branches of the resilient strip 134 at the corner joint. Wall joints at the inside of the wall section can be finished with trim pieces received in end parts 56, 58 of the resilient strip 134, with removable tape or any other manner satisfactory to the purpose.
FIGS. 3 and 5 illustrate the manner of installation of interior wall members 110a-110c. The interior wall members can be installed easily and quickly in several ways involving minimum use of fasteners such as nuts and bolts except at the tops of the wall members or at the ends of a partition section. For example, an interior wall section subdividing a space and intersecting another wall section can be easily installed by first fixing a resilient strip 134 (FIG. 3) to the skin 122 of one wall member 110a, the strip 134 being secured on skin 122 with nails 202, adhesive or other fastening means, the strip installation being effected such that the longitudinal direction of the tongue part 132 extends perpendicular to the floor surface. A second resilient strip 134 is then laid on the floor 204 (FIG. 5) in the precise location where the wall is desired and aligned so that its tongue part 132 is at a right angle with the vertically disposed tongue part of the first installed strip, i.e., that fixed to the wall member. The floor laid resilient strip is then fixed in place on the floor, as for example, by nailing. In this manner, the wall member mounted and floor mounted resilient strips provide locator means to insure that the interior wall member 1101) can be installed with proper alignment to wall member 110a without leveling, measuring, etc. The wall member 11% is then set in place with the groove 30 in frame member 117 receiving the tongue part 132 of the wall mounted strip 134 (FIG. 3) and the groove 30 in frame member 114 receiving the tongue part 132 in the floor mounted strip 134 (FIG. 5).
FIG. 5 shows the manner in which the upper or top parts of interior wall sections are secured to associated building supporting surfaces. As a preliminary it will be noted that with respect to interior wall section wall members, the panel skins may each be of the same thickness and composition since not being exposed to the elements such panel skins can be of a lighter gauge. As was indicated above, the bottom part of the interior wall member 1101) is secured to the floor slab or other floor structure 204 by being supported solely through the agency of the resilient strip 134. At the top, suitable connection can be provided by bolting through the upper horizontal frame member 112 of the wall member 11% to an overhead structure such as a cross beam connected to the bottom chord of a truss. Such beam 210 also provides a surface for securing ceiling pieces 300, and the ceiling wall corner sections of the room spaces can be finished off with molding strips 214 nailed directly to the panel skins.
Referring again to FIG. 3, interior wall structure can be provided at certain locations with a door 270 in the same manner as that described with respect to the exterior Wall structure depicted in FIG. 2 and be supported on frames or battens 272 connected with the ends of the Wall members 10. Since not all interior wall structure will terminate at another wall, it may be advantageous in connection with partition segments such as the wall member 11012 to finish off the end of the partition with a suitable capping piece or batten 230 which can be bolted to the terminal edge of interior wall member 1100 in the manner shown.
It will be evident from reading the foregoing description that the present invention provides an important improvement in prefabricated structures. Aside from the ease of erection and dismantling of structures provided herewith, it includes many features which enhance the overall integrity of the structure. For example, as illustrated in FIG. 4, a combination vapor barrier seal and thermal break element 300 can be provided around the edge of the foundation or slab 82 of the structure. Such seal 300 has an upper tip end portion 301 which can be placed so that it interfits with the branch ends of the resilient strip 134 underlying the exterior wall section wall member 10, thereby establishing an impenetrable barrier to vapor. Also, as will be noted in FIG. 5, the wall members provide for simple yet effective means for decoratively finishing the building spaces. For example, a moulding strip 256 can be snapped into place at the floor-wall member joint, being received in the branches of the resilient strip 134. Alternatively, conventional moulding 250 can be adhesively tacked or otherwise secured to the wall member skin as shown. As was mentioned earlier herein, the present invention provides that a prefabricated structure provided thereby possesses excellent characteristics of soundproofing. This results from the use of the resilient strip 134. Alternately, conventional moulding 251) wall member so that vibration can neither enter nor leave the wall member structure itself. At each joint in the structure, such resilient strip members function to dampen any vibration coming from supporting structure such as floor or overhead beams to prevent transmission of sound vibrations to the wall members. Similarly, if such vibration should be created directly in a particular wall member by any agency, the vibrations cannot leave the particular wall member and enter others or the various support structures in the structure. Moreover, such vibrations are for the most part absorbed in the wall member per so by the thermally insulative layer 66.
