M 4 \\\y kg ROOF ASSEMBLIES FOR BUILDING STRUCTURES This application is a eontinuation-in-part of co-pending application Ser. No. 160,018 filed on July 6, 1971, now abandoned and entitled Modular Building" which is in turn a continuation-in-part of Application Ser. No. 85,533 filed on Oct. 30, 1970, now abandoned and entitled Building Structures.

The present invention relates generally to buildings and more particularly to building systems including the use of standardized roof assemblies.

A large number of perfabricated and modular housing systems have been formulated over the years, but for various reasons, there has been little acceptance or success with such systems.

The prefabricated systems which have been presented for commercial use are generally comprised of a large number of components that are usually not standardized, and therefore must be constructed by skilled craftsman with careful attention to plans.

Furthermore, such systems have generally been unattractive in appearance, such that any savings in cost has not been proved to be an incentive to the adoption of such systems, particularly in low and middle cost hous As the shortage of housing grows, the need has deepened for an effective modular building that can easily be constructed by unskilled workmen with standardized components and at a low cost.

In the above mentioned application Ser. No. 160,018, whose disclosure is incorporated by reference herein, there is disclosed and claimed novel studs which are standardized and can be readily fabricated from roll steel stock when needed. The standardized studs eliminate the need for large inventories of parts, which heretofore has been required of prior art housing systems. Furthermore, the studs are so configured as to enable a large number of parts, such as wall panels, to be readily connected without special tools by relatively unskilled labor and without the use of nails or threaded fastening means. Further still, the joints between the panels connected by the studs are not exposed and do not require spackling, tape or other retaining means. In addition to the above noted features, the stud also includes openings to permit the assembly of electrical wiring, piping, heating and ventilating ducts therethrough.

As disclosed, the studs basically comprise a pair of half-stud members held together by rotating clamps. The halfstud members are preferably of identical construction, each including a first longer wall and a second shorter wall, the first and second walls run generally parallel to each other and are connected by a bridging section. Each wall terminates in a free edge tab portion. The two half-stud members are disposed against each other in such a way that the longer first wall of each half-stud member is immediately adjacent to the other, such that the respective tabs of the first and second parallel walls extend away from each other. A vinyl separator is interposed between the adjacent first flat parallel walls and possesses an exterior seal at one end and an interior seal at the other end.

The walls are erected by providing an exterior panel having longitudinal grooves formed in the interior surface adjacent its vertical edge. A half stud member is attached to the panel at its vertical edge with the tab of a second parallel wall of the first half-stud member being received in the longitudinal groove of the panel. The exterior panel with its half-studs is then so positioned with respect to a previously erected wall panel (which already has a half-stud associated therewith) so that the half-stud of the previously erected wall panel and the nearest half-stud of the panel about to be erected, may be secured together by rotating clamps after a vinyl separator has been interposed between the first parallel walls of the two half-studs.

Also disclosed in said application Ser. No. 160,018 is a novel spring clip to enable a half-stud member to be simply and securely fastened to a horizontal wall plate. The clip has other fastening functions, one of which being to secure the half-stud members to a supporting brace.

The clip essentially comprises a body portion from which a tab portion extends at one end thereof, with the spring finger extending from the other end of the body portion. The clip is adapted to snap into a pair of slots that exist in the adjacent walls that are to be secured together. To that end, the tab portion of the clip is simply slipped into one of the slot pairs and the spring finger is passed through the other slot pairs and allowed to move in a locking position.

In co-pending application Ser. No. 339,796, filed on Mar. 9, 1973, US. Pat. No. 3,867,802 whose disclosure is incorporated by reference herein, there is disclosed a floor support assembly for modular building systems. Like the novel studs of application Ser. No. 160,018, the floor support assembly is formed of standardized parts which can be fabricated when needed, can be put together by relatively unskilled workmen without special tools and can be used to serve as heating and/or cooling duct work.

The floor support assembly comprises a joist, a beam having a joist supporting ledge and a locking clip for connecting the joist to the beam. The joist includes an elongated bottom wall portion and a pair of sidewalls projecting along the length of the bottom wall at an angle thereto so as to form a generally V-shaped member. Each sidewall of the joist includes a ledge extending therealong. The ledges are coplanar and are adapted to be received within respective grooves in a floor panel to support the floor panel thereon.

The joist itself is supported at its end by the ledge of the beam and is connected to the beam by a rod-like clip.

The clip includes an elongated body portion, a short leg and a long leg projecting laterally from opposed ends of the body portion and in the opposite direction thereto. The long leg terminates in a projecting ear. The short leg of the clip extends through an opening in the bottom wall of the joist adjacent the end and an aligned opening in the ledge disposed thereunder. The long leg of the clip extends through an opening in the sidewall of the joist's flange with the projecting ear thereon extending into an opening in the beam.

The beam includes a flanged portion for connection to a similar beam to form a hollow beam section which not only serves as a support for other floor joists, but also serves as heating and/or cooling duct.

1n co-pending application Ser. No. 358,193, filed on May 7, 1973, whose disclosure is incorporated by reference herein, there is disclosed foundation assemblies for modular building systems. Like the studs of application Ser. No. 160,018 and the floor support assemblies of application Ser. No. 339,796, the foundation assemblies are formed of standardized parts, which can be fabricated when needed, and can be put together by relatively unskilled workmen without special tools. As disclosed, the foundation assemblies basically comprise sill means and a wall plate connected thereto. The wall plate serves to support a plurality of elongated half-stud members on which vertical wall panels are mounted.

In one embodiment, the sill plate is mounted directly on and is connected to a concrete foundation element and comprises a sill plate and a sill locking plate. A flanged stud tie plate is interposed between the sill locking plate and the wall plate and serves to expedite the mounting of the stud members. In another embodiment, the sill means is mounted on a vertically extending pier for supporting the sill plate and associated structure above the ground. In that embodiment, the sill means comprises a sill plate, a sill locking plate and a beam support angle having a portion connected to the pier and the sill plate for supporting the beam of a floor support assembly. In yet another embodiment, the sill means is mounted directly on the ground and includes a channel-like mud sill and a mud plate adapted to be staked to the ground and having a resilient portion for urging the mud sill into secure engagement with the ground. In still another embodiment, a corner bracket is provided for interconnecting two sill means and associated structural components to support a corner of a foundation assembly. In yet another embodiment, a hollow floor support beam of a floor support assembly is mounted above the ground on a vertically extending pier. The pier is connected to the floor support assembly via a pair of interconnected beam support angles.

Heretofore, various roof assemblies for modular building systems have been proposed, but such systems have suffered from various deficiencies, such as for example, they require large inventory of specially fabricated parts, they are complex, they require skilled workmen or special tools for assembly and are relatively expensive.

It is a general object of this invention to provide roof assemblies which overcome the above described disadvantages of prior art roof assemblies.

It is a further object of this invention to provide novel roof assemblies formed of standardized components which can be fabricated when needed, and can be readily assemblied by relatively unskilled workmen without special tools.

It is a further object of this invention to provide a novel clip for connecting roof panels to one another.

These and other objects of this invention are achieved by providing a roof assembly for a building including a planar roof panel, a rafter having a free end for supporting the roof panel directly thereon and an elongated tie bar connected to the rafter adjacent its free end. The rafter is supported adjacent its free end on the upper end of a vertical wall stud by a top wall plate and comprises a pair of elongated members held together by clamp means. The rafter includes another end which is supported and abuts an elongated and normally extending ridge pad and ridge member. The free end of the rafter abuts an elongated and normally extending end plate and associated fascia means. The tie bar is connected to the rafter adjacent the free end thereof, via a rafter tie pin. A channel-like clip is provided to connect adjacent roof panels to one another.

Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the follow- 4 ing detailed description when considered in connection with the accompanying drawings wherein:

FIG. 1 is a perspective view, partially in section, of a portion of a roof assembly in accordance with this invention;

FIG. la is a schematic representation of the arrangement of FIGS. 1 and 2 in order to clearly show the details of the entire roof assembly;

FIG. 2 is a perspective view of another portion of the roof assembly;

FIG. 3 is a sectional view taken along line 3-3 of FIGS. 1 and 2;

FIG. 4 is an exploded perspective view of a portion of the assembly shown in FIG. 2;

FIG. 5 is an enlarged sectional view taken along line 5-5 of FIG. 3;

FIG. 6 is a sectional view of a pair of adjacent wall panels which are connected by a clip in accordance with one aspect of this invention;

FIG. 7 is a sectional view of a pair of adjacent roof panels which are connected by the clip shown in FIG. 6 but oriented differently than shown therein; and

FIG. 8 is a sectional view showing means for connecting portions of the roof assembly to one another.

Referring now in greater detail to the various figures of the drawing wherein like reference characters refer to like parts, a roof assembly in accordance with this invention is shown generally at 20 in FIG. 1.

Assembly 20 basically comprises a plurality of rafters 22 for supporting a plurality of roof panels 24, such as plywood sheets, thereon. The rafters are arranged in two angularly related sets, each set includes a plurality of parallel and coplanar rafters forming a side of a pitched roof. The rafters of one set are aligned with the rafters of the other set with one end 25 of the rafters of each set being connected to the corresponding end of the rafters of the other set by a normally extending ridge assembly 26. The assembly 26 forms a roof peak. The free end 28 of each rafter of one set is connected to the free end of a corresponding rafter of the other set by respective tie bars 30 (FIG. 2). The tie bars 30 serve to brace the rafters 22 and thus strengthen the roof assembly. Each rafter 22 is supported adjacent its free end 28 on the upper end of a vertical wall stud 32 by a wall plate 34. An elongated fascia assembly 36 abuts the free ends of associated rafters to close the rafters and provide additional support for the roof panels mounted thereon. The roof panels 24 are connected to one another via a plurality of connection clips 38.

In accordance with a perferred aspect of this invention, the individual components forming the roof assembly 20, except for the plywood roof panels, connecting clamps and tie bars, are formed of roll steel stock such as 20 gauge roll steel stock, and can be readily fabricated when needed.

This feature is of considerable importance in the housing construction industry where heretofore, the maintenance of large inventories was required in order to permit the construction of buildings from standardtype parts. Needless to say, such large parts inventories result in increased overall building costs due to the increased storage and handling costs attendant with such inventories. Furthermore, by eliminating large inventories, the problem of having surplus parts left over once the building is completed, is minimized, if not eliminated.

As can be seen in FIGS. 1 and 2, each rafter 22 comprisesa pair of identical elongated members 40. Each member is of the same shape as the half-stud members shown and described in application Ser. No. I60,0l8 and comprises a first longer wall 42, a second shorter wall 44, with the

walls

42 and 44 being generally parallcl to each other and possessing longitudinal crimps 46 for strengthening purposes. The

walls

42 and 44 are joined together by a bridging section 48 and terminate in

free edge tabs

50 and 52, respectively, which define a space therebetween. The two elongated members are disposed against each other in such a way that the longer first wall of each member is immediately adjacent the corresponding wall of the other, whereby the respective free edge tabs of the first and second parallel walls extend away from each other.

The two elongated members 40 are secured together by means of rotating clamps 54 like those shown and described in application Ser. No. 160,018. The clamps 54 are basically U shaped and are comprised of a base 56 and a pair of legs 58. The rotating clamp 54 is inserted through aligned slots 60 in the walls of the elongated members 40. The slot 60 includes an enlarged central portion 62 so that when the legs of the clamp are inserted through the slot, the legs are in actual contact with crimps 46 in each of the second shorter walls 44 of the elongated members 40.

The insertion of the rotating clamp 54 is usually done in such a manner that the legs 58 are passed through the narrow portions of the slot 60 in each of the first and

second walls

42 and 44. The clamp 54 is then rotated about base 56 as an axis so that the legs 58 are rotated away from the slot and into a transverse direction with respect to the elongated member.

The legs 58 are so dimensioned and spaced with respect to each other that they are separated by a distance slightly less than the distance between the convex crimps 46 in the parallel second shorter wall 44. Thus, as clamp 54 is rotated into the transverse direction, the legs 58 exert an inward force upon the second shorter walls 44, thereby uniting the two elongated members 40 to form a unitary rafter. In actual practice, it is preferred that two rotating clamps 54 be used for each pair of elongated members 40.

The rafters 22 of one set are connected to and mounted on a top plate 34 (FIG. 2). The top wall plate is an elongated member which in turn is mounted on an elongated top sub-wallplate 64. The top sub-wallplate 64 is in turn mounted on the top ends of a plurality of vertical wall studs 32, only one of which can be seen (see FIG. 3). The wall studs 32 are of identical construction to those disclosed in application Ser. No. l60,018.

As can be seen in FIG. 3, the top wallplate 34 comprises a base wall 68 having a flange 70 projecting normally from one side thereof. The flange 70 terminates in an angularly extending lip 72. The lip extends at the same angle with respect to the base wall of the top plate as the degree of the pitch of the roof such that the lip abuts the bridging section 48 of the rafters. The lip 72 includes a plurality of transversely extending slots (not shown). The slots are provided to align with longitudinally extending slots (not shown) in the bridging section of the elongated members making up each of the rafters, such that a spring clip 74 can be inserted in the aligned slots to secure the rafter to the top wall plate. The spring clip 74 is of similar construction to that disclosed in application Ser. No. 160,0[8 and basically comprises a body portion 76 from which a tab portion 78 extends at one end and a spring finger 80 extends at the other end.

In FIG. 8 there is shown the manner in which a typical spring clip 74 is utilized to connect two components having aligned slots therein. To that end, the tab portion 78 of spring clip 74 slipped into an aligned slot pair and the spring finger 80 is passed through another adjacent aligned slot pair and allowed to move into a locking position, thereby securing the two components together.

As can be seen in FIG. 3, the other side of the top wallplate 68, i.e. the side opposed to the flanged side, terminates in a portion 82 which is offset at an angle from the basewall 68 and is coplanar with the lip 72. Accordingly, the offset portion also abuts the bridging section 48 of the rafter 22 and thus serves to provide additional support therefore.

The top sub-wallplate 64 is an elongated member of identical construction to the elongated members 40 forming the rafters 22 and is mounted across the upper ends of the plural wall studs 32 forming a wall of the building structure. The top sub-wallplate 64 serves to hold the upper edge of a vertical wall panel 84 in place by securing its top horizontal edge within the space defined between the

free edge tabs

50 and 52 of the top sub-wallplate, with free edge tab 52 being disposed within a horizontal groove 86 in the wall panel adjacent its edge.

The top sub-wallplate is connected to the upper ends of the wall stud 66 via a stud tie plate 88. The stud tie plate is an elongated member comprising a horizontal base portion 90 and a vertical flanged portion 92 projecting normally therefrom. The base portion 90 includes an opening (not shown) and a longitudinal crimp for locking and strengthening purposes. The flanged portion 92 includes a plurality of transverse slots 94 which align with longitudinal slots (not shown) in the wall studs and with transverse slots (not shown) in the bridging section of the top sub-wallplate 64. Spring clips 74 are inserted in the aligned slots to complete the connection between the top subwallplate and the vertical wall studs 66.

The top wallplate 34, the stud tie plate 88 and the top sub-wallplate 64 are secured together by means of rotating clamps 54 in an identical manner to the manner in which the elongated members 40 are connected to each other to form a rafter.

As can be seen in FIGS. 2 and 3, the free end 28 of the rafters 22 of each set is closed by a respective elongated fascia assembly 36 which extends normally to the rafters of that set. The fascia assembly comprises a rafter end plate 94, whose construction is identical to that of the elongated members 40, a rafter tie plate 96, whose construction is identical to the stud tie plate 88, an elongated sub-fascia 98 and an elongated fascia 100. The rafter end plate serves to support the edge of a roof panel 24 between its

free edge tabs

50 and 52, with tab 52 disposed within groove 86 in the panel (see FIG. 3). The rafter end plate 94 is secured to the end of the rafters by the elongated rafter tie plate 96 in the same manner as the manner in which the stud tie plate 88 secures the top sub-wallplate 64 to the upper ends of the wall studs 32, Le. via spring clips 74 extending through aligned slots in the adjacent components.

The sub-fascia 98 is of identical construction to the top wallplate 34 and is connected to the rafter end plate 94 in the identical manner to the manner in which 7 the top wallplate is connected to the top sub-wallplate 64, i.e. via rotating clamps 54.

The fascia 100 includes a base portion 100 terminating at one side thereof in a groove 104. The groove 104 is formed by bending the base portion back over itself and serves to receive the edge of the lip 72 of the subfascia 98 to thereby hold the fascia in place. The other side of the fascia I terminates in an angularly extending flange I06. A crimp 108 extends the entire length of the fascia member closely adjacent to the point at which the flange 106 meets the base 102. The crimp 102 serves to lock the fascia to the sub-fascia. To that end, the crimp is disposed within the space defined between the offset portion 82 of the sub-fascia 98 and the longer wall 42 of the rafter end plate 94. The angularly projecting flange 106 of the fascia serves to hold the edge of the roof panel 24 down and in place.

Means are provided to enable a soffit (not shown) to be mounted under the portion of the rafters extending outward from the wall of the building structure to close that portion thereof. To that end, a soffit molding 110 is secured to the rafter immediately adjacent the point at which the rafter meets the wall of the building structure and another sofflt molding 112 is connected to the rafter end plate 94.

As can be seen in FIG. 3, the soffit moldings 110 and 112 are of identical construction and comprise an elon gated base portion having a first lip 116 slightly offset from the plane of the base and extending the entire length of the molding. The molding includes a second lip greatly offset from the base on the opposed side thereof and extending the entire length thereof. A plurality of transverse slots (not shown) are provided in the base of the soffit moldings I and 112. The slots in the base of the soffit molding I10 serve as a means for connecting it to the rafters. To that end, the slots in the base of the soffit molding are aligned with longitudinally extending slots (not shown) in the bridging section 48 of the rafters and spring clips 74 are inserted in the aligned slots to complete the connection. The transversely extending slots in the soffit molding 112 serve as the means for connecting the soffit molding to the rafter end plate 94. To that end, the slots in molding 112 are aligned with transversely extending slots (not shown) in the bridging section of the rafter end plate and spring clips 74 are inserted in the aligned slots to complete the connection. Once the soffit moldings are connected as shown, a soffit may be readily attached thereto to close the underside of the overhanging rafters.

The ends 25 of the rafters of each set are connected together by the ridge assembly 26 to form the ridge or peak of the roof. The assembly 26 is formed of two identical pairs of components which, as can be seen in FIGS. 1 and 3, comprise ridge pads 122 and ridges 124. The ridge pad 122 is of identical construction to the top wallplate 34 and the sub-fascia 98 and the ridge 124 is of identical construction as the fascia 100.

The ridge 124 supports the ends 25 of each of the rafters 22 of an associated set and is connected thereto by plural spring clips 74. To that end, a spring clip is inserted within a slot in the flange 106 of ridge 122 and an aligned transverse slot in the bridging section of the elongated member forming the rafter. The end 25 of the rafter abuts the base portion 68 of the ridge pad 122. As can be seen, the width of the base portion of the ridge pad is of the same dimension as the height of the rafter 22 such that the flange 70 of the ridge pad supports the edge of at least one roof panel 24, thereby aiding the rafter 22 in supporting said panel.

The two ridges 124 of the ridge assembly 26 are connected to one another to form the roof peak by abutting their base portions 102 such that transverse slots 126 therein (see FIG. 1) are aligned. Spring clips 74 are inserted in the aligned slots to complete the connection.

Each of the tie bars 30 is connected between the free end 28 of a rafter 22 of one set and the free end 28 of the aligned and corresponding rafter 22 of the other set. The tie bars serve to brace the rafters connected thereto and thereby strengthen the roof assembly.

As can be seen in FIGS. 2 and 3, the tie bar 30 is an elongated member having a T-shaped cross section formed by a relatively thin web 126 and a strengthening flange 128. The web and the flange are cut away at each end of the tie bar in order to provide reduced width web 130 portion at each end of the bar. The reduced width portion is interposed between the elongated members forming the associated rafter (see FIG. 4) closely adjacent the free end thereof. The tie bar is connected to the rafter at this location by a rafter tie pin 132. The rafter tie pin is a cylindrical member or tube which extends through a hole 134 in the reduced width web portion 130 of the tie bar. The ends 134 of the tie pin are held in place by respective pin retainers 136. The pin retainers are mounted within aligned slots 60 in the rafters. To that end, the pin retainers are of generally U-shape having an enlarged opening or mouth 138 formed by arcuate sides 140 which fit into the enlarged opening 62 in the slot 60. The mouth 138 serves to receive the tie pin end to secure it to the rafter. An inwardly projecting flange 142 is provided along the periphery of one side of each pin retainer to act as a stop and thereby prevent the tie pin end disposed therein from sliding longitudinally. An outwardly projecting flange 143 is provided along the periphery of the arcuate portions on the other side of the pin retainer. This flange abuts the surface of the wall of the elongated member contiguous with slot 62 to secure the pin retainer to the member 40.

In the sectional view of FIG. 5 there is shown the completed connection between the tie bar 30 and rafter 22. As can be seen, the tie pin 132 is disposed within a pair of pin retainers 136 with its ends abutting the flanges 142 of the respective pin retainers. The tie pin extends through hole 131 in the reduced width web portion I30 of the tie bar to secure the tie bar to the rafter.

In accordance with one aspect of this invention, a novel clip 38 (FIG. I) is provided for connecting the roof panels 24, or any other type of planar panel, to one another edge-to-edge to maintain their surfaces at the same plane even under uneven loading conditions. The clip 38 is also effective when used in conjunction with panels having grooves in their faces closely adjacent the edge, like the roof panels 24 and the wall panels 84, to prevent the panels from separating during the assembly operation.

As can be seen in FIGS. 2, 6 and 7, the connection clip 38 is of generally ch annel-like shape and comprises a web or a base 144 having a pair of sides 146 projecting normally therefrom and extending the length of the clip. The sides define a space therebetween into which an edge of one roof panel 24 is disposed. Two pair of ears I48 are bent out of the plane of the base to extend normally thereto and in the opposite direction as the 9 sides 146. The ears of each pair also define a space therebetween into which the edge of an adjacent roof panel is. disposed.

In order to secure theclip to one panel and thereby strengthen the joint between the panels, a pair of pointed tags I50 are bent out of the plane of the base to extend normally thereto and in the direction which the ears extend. The tags are adapted to penetrate into the edge of the panel which is inserted between the ears and thereby affix the clip to that panel. In the sectional view of FIG. 6, a completed connection between two adjacent roof panels 22 is shown. As can be seen, one edge 152 of one panel is disposed between the sidewalls 146 of the clip 38 and one edge 154 of the other panel is disposed between the'ears 148 of the clip with the tags 150 penetrating into the latter edge.

In FIG. 7 there is shown the manner which the clip 38 can be used to hold a pair of adjacent roof panels 24 together during the assembly operation. As can be seen, in such a case the clip is oriented such that one pair of ears 148 is disposed within the groove 86 adjacent one edge of one panel and the other pair of cars disposed within the groove 86 adjacent one edge of the other panel. in order to hold the clip in position, one pointed tag 150 penetrates a portion of one panel adjacent its edge and the other tag penetrates a corresponding portion of the other panel.

As should be appreciated from the foregoing description, the roof assembly in accordance with this invention is relatively simple and inexpensive, can be fabricated when needed and can be readily assemblied and locked in place utilizing simple clips without skilled labor and without special tools. All of the above features make the roof assemblies ideal building components for producing low cost, yet attractive buildings of various overall designs.

Without further elaboration, the foregoing will so fully illustrate our invention that others may, by applying current or future knowledge, readily adapt the same for use under various conditions of service.
