Metal framing system

Abstract

A system and method are provided for framing at least a portion of a wide variety of structures. In each embodiment, the framing system includes a base, which may be attached to a foundation of the structure by conventional means, which preferably comprises at least one rectangular or square metal tube. Alternatively, the base may be made of other metal structures. The framing system further includes a plurality of lower connecting members attached to and extending upwardly from the base and a plurality of upwardly extending support members which are interconnected to the lower connecting members. The framing system may further include an upper member and a plurality of upper connecting members attached to and extending downwardly from the upper member. Each of the support members is also interconnected to one of the upper connecting members, which is aligned with one of the lower connecting members. The interconnections between the support members and the corresponding lower and upper connecting members may be achieved by various alternative configurations, but in each case one member has a reduced end portion which is inserted into a non-reduced end portion of the adjacent member. The reduced end portion is preferably achieved by a roll reduction process.

Description

BACKGROUND

1. Field of the Invention

The present invention relates generally to framing systems used in the construction of buildings, and more particularly to a metal framing system which incorporates hollow metal tubing.

2. Related Art

Known framing systems used in the construction industry are typically made of either wood or metal, with wood framing systems being the most common. As is well known, wood framing systems have enjoyed widespread use, for instance in the construction of residential homes. Wood frames are typically constructed by connecting pieces of wood, such as 2×4's or 2×6's, with nails in a form that creates either the interior or exterior outline of a structure, or both. In known wood framing systems, all major components are typically made of wood, including components which may be referred to in the art as the bottom plate, studs, top plate and roof trusses. With the exception of roof trusses, which utilize miter cuts on the ends of adjacent pieces of wood to accomplish the desired angular relationship between adjacent members, most wood framing systems consist primarily of straight 2×4's nailed together to define the outside and inside areas of the structure and to provide the load bearing support.

Although wood framing systems have enjoyed widespread use, they are subject to several disadvantages. For instance, the process of constructing a wood framing system is relatively slow since all joints within the system are typically connected with several nails. For example, even if the included roof trusses are pre-assembled, it typically takes a framing crew of four people between five and seven working days to frame a 1,500 square foot house.

Furthermore, the quality of the workmanship associated with the construction of wood framing is often poor, especially in conjunction with low and moderate priced housing where builder's profit margins are relatively low and building costs are suppressed as much as possible. The primary result of this poor workmanship is typically the lack of squareness in the structure frame which adversely affects the installation of other components in the structure.

Other disadvantages associated with wood framing is the flammability of wood, and the potential for deterioration due to exposure to weather or insects such as termites or carpenter ants. Another disadvantage is that the system strength may be reduced at angled connections which require a miter cut and attachment with either nails or screws. Yet another disadvantage associated with use of wood framing systems is the depletion of wood as a natural resource.

Although metal framing systems may represent an improvement relative to wood framing systems with regard to improved strength and reduced deterioration, known metal framing systems are also typically subject to one or more disadvantages. For instance, like a wood framing system, the assembly of a metal framing system may be very time consuming since the metal framing system may require nearly as many metal screws as the nails used in a comparable wood framing system to connect adjacent metal components. Moreover, the screws are generally not as quickly inserted as nails, and therefore the metal framed structure may actually require more time to assemble than a comparable wood framed structure. These and other disadvantages associated with metal framing systems may be further illustrated by the following discussion of known metal framing systems.

Metal framing systems have been used for some time in commercial construction and have recently become more popular in residential construction. Known metal framing systems used in these applications commonly include metal components which are formed as three-sided channels, such as U-channels. For instance, these systems may include vertically extending metal channels, which are inserted into the open side of horizontally extending metal channels used for the bottom and top members of the metal framing system. The joints between the vertically and horizontally extending members are typically secured with numerous fasteners such as screws. Additionally, metal straps are often utilized to secure the vertically extending channel members to one another. Accordingly, the assembly of a metal framing system of this type may be very time consuming due to the requirement to secure the numerous fasteners and metal straps.

Another known metal framing system, which is used to frame a carport, utilizes round hollow tubing with one end of each of the round tubing members being inserted into the hollow end of an adjacent round tubing member. The joint between the two round tubing members may then be stabilized with conventional fasteners. The male portion of each joint may be accomplished by a swaging process to reduce an end portion of the corresponding round tubing member. Although the foregoing carport framing system has been advantageously utilized, use of round metal tubing makes it difficult to insert fasteners into the tubing joints which complicates the assembly of the framing system. Furthermore, in some applications, such as when the carport is placed adjacent to a residential structure, the carport frame may not be viewed as aesthetically appealing.

It is often more advantageous to use either square or rectangular metal tubing in certain applications. However, the connection of adjacent components of square or rectangular metal tubing has been subject to the following problems. Known methods of reducing square and rectangular metal tubing include those which utilize one or more dies. With this form of reduction, one end of the square or rectangular tube is crushed by the force created by various configurations of press equipment, with the size of the reduction being determined by the die design. This method of end reduction of square and rectangular metal tubing is subject to the following disadvantages. In the first instance, the end reduction of the tubing may require several “hits” or applications of the press equipment to achieve the desired reduction, with each application adding to the manufacturing cost. Furthermore, the crushing force of the press equipment may cause excessive and/or non-uniform deformation of the tube end. More specifically, one or more sides of the tubing may become concave, thereby reducing the overall strength of the tube and detracting from the smoothness of the transition between the original shape and the reduced end. In certain instances, the excessive and/or non-uniform deformation may be so severe that the reduced end of the tube is not capable of insertion into a tube of the same size prior to reduction, as intended.

Due to the foregoing problems associated with the use of dies to end reduce square and rectangular tubing, connections of adjacent lengths of like-sized square and rectangular metal tubing has generally been accomplished by inserting a smaller tube, of the same shape, inside two adjacent like-sized pieces of rectangular or square metal tubing, and then securing the joint by fastening each section of the outer tubes to the inner tube. Framing systems of this type have been used to frame carports. The inner tube, as well as the required fasteners, add to the cost of this method of joining adjacent sections of square or rectangular metal tubing. Another disadvantage associated with this type of metal framing system is that the strength of the included joints may be be limited to the strength of the required fasteners at each joint.

In view of the foregoing disadvantages associated with known wood and metal framing systems, there is a continuing need for improved framing systems for use in the construction of a wide variety of buildings including residential and commercial structures.

SUMMARY

In view of the foregoing needs, the present invention is directed to a simple, cost effective and efficient system and method for framing at least a portion of a wide variety of structures including, but not limited to the following structures: residential homes; carports; commercial buildings such as office, retail, mini-storage and industrial buildings; apartment and condominium buildings; office build-out and commercial buildings; utility buildings; and modular/kiosk structures. The framing system and method of the present invention utilizes either rectangular or square metal tubing, or a combination thereof, and therefore has several advantages over existing wood framing systems or metal framing systems utilizing components other than rectangular or square metal tubing. For instance, due to the use of rectangular or square metal tubing, systems embodying the principles of the present invention exhibit improved mechanical strength relative to similar wood framing systems or various metal framing systems such as those which utilize open channel members.

The ease of assembling various components of the framing system of the present invention allows a significant reduction in time, and therefore of cost, in framing various structures relative to prior wood or metal framing systems. For instance, the speed of assembly and therefore the reduction in cost associated with the apparatus and method of the present invention is accomplished by interconnecting various components of the framing system by inserting a reduced end portion of one member or component into an adjacent component which is constructed of a like-sized and similarly shaped metal tube, i.e., either rectangular or square, which has not been end reduced. As an example of the time and cost reductions which may be realized using a framing system embodying the principles of the present invention, a 1,500 square foot house may be framed in less than one day using a crew of four people whereas it typically takes a similar sized crew between five and seven working days to frame a similar structure using wood.

The various components of the framing system of the present invention may be manufactured in a plant setting where relatively stringent quality control measures may be applied, resulting in improved workmanship relative to a comparable wood framed structure. More particularly, the squareness of the frame may be significantly improved relative to the squareness of a comparable wood framed structure, which is often less than desirable, especially in low and moderate priced housing where builder's margins are relatively low and costs are typically suppressed as much as possible.

The rectangular and square metal tubes incorporated in the framing systems of the present invention have four sides and a welded seam. Assuming similar size and wall thickness, these metal tubes are significantly stronger than the three-sided metal channels used in many known metal framing systems. Also, as compared to a wood stud, similar sized metal tubing is significantly stronger. Additionally, the four sides of the rectangular and square metal tubes provide flat surfaces which facilitate the attachment of other structures to the framing system.

Another advantage of the framing system of the present invention, at least with respect to prior wood framing systems, is that the metal framing system of the present invention is not subject to deterioration from insects, rotting or warping. Furthermore, the metal framing system of the present invention is not flammable.

According to a first aspect of the present invention, a system is provided for framing at least a portion of a structure which may include a foundation. According to a preferred embodiment, the system includes a base which may be attached to the foundation of the structure, and a plurality of lower connecting members attached to the base and extending upwardly therefrom. Each of the lower connecting members comprises a metal tube selected from the group consisting of rectangular metal tubes and square metal tubes. The system further includes a plurality of upwardly extending support members which also comprise a metal tube selected from the group consisting of rectangular metal tubes and square metal tubes. A plurality of lower joints interconnect the support members and lower connecting members with each of the lower joints interconnecting one of the support members and one of the lower connecting members. The support members have a cross-sectional shape which is substantially the same as the cross-sectional shape of the interconnected one of the lower connecting members. For instance, if the lower connecting member comprises a rectangular metal tube, then the corresponding, interconnected one of the support members also comprises a rectangular metal tube. For each of the lower joints, either the support member or the lower connecting member has a reduced end portion which is inserted into the other of the support member and interconnected one of the lower connecting members.

In one embodiment the reduced end portion, which corresponds to the male portion of the lower joint, comprises the lower end portion of the corresponding support member which is inserted into the interconnected one of the lower connecting members. This may apply to at least a portion of the lower joints. In another embodiment, the reduced end portion comprises an upper portion of the corresponding lower connecting member which is inserted into the interconnected one of the support members, for each one of at least a portion of the lower joints.

The system may further include an upper member, which may be substantially horizontally extending or may alternatively be sloped relative to horizontal. The upper member preferably comprises either a rectangular metal tube or a square metal tube, with the selection depending upon the cross-sectional shape of the support members included in the framing system. A plurality of upper connecting members are attached to the upper member and extend downwardly therefrom, with each of the upper connecting members comprising a metal tube selected from the group consisting of rectangular metal tubes and square metal tubes.

A plurality of upper joints interconnects the upwardly extending support members and the upper connecting members with each of the upper joints interconnecting one of the support members and one of the upper connecting members. The cross-sectional shape of each of the support members matches the cross-sectional shape of the interconnected one of the upper connecting members. For each of the upper joints, either the support member or the upper connecting member has a reduced end portion which is inserted into the other member. In one embodiment, the reduced end portion of each one of at least a portion of the upper joints comprises the upper end portion of the corresponding one of the support members, with the upper end portion being inserted into the corresponding, interconnected one of the upper connecting members. In another embodiment, the reduced end portion of each one of at least a portion of the upper joints comprises a lower end portion of the corresponding one of the upper connecting members, which is attached to the upper member at an upper end portion thereof, with the lower end portion of the upper connecting member being inserted into the corresponding, interconnected one of the support members.

The reduced end portion of each of the upper and lower joints is preferably formed by a roll reduction process, in which the end of the corresponding rectangular or square metal tube to be reduced is inserted into a tool having a plurality of rollers which are configured and arranged to accomplish the desired end reduction of the tube. This process is disclosed in co-pending U.S. patent application Ser. No. 08/957,354.

According to another embodiment, a system is provided for framing at least a portion of a structure having a foundation, such as a residential home. The system comprises a plurality of exterior wall frames interconnected to one another and extending upwardly from the foundation of the structure. Each of the wall frames includes a base attached to the foundation, a plurality of lower connecting members attached to the base and extending upwardly therefrom, and a plurality of upwardly extending support members, with each being interconnected to one of the lower connecting members by one of a plurality of lower joints. Each of the lower connecting members and each of the support members comprises a rectangular metal tube. For each of the lower joints, either the support member or the lower connecting member has a reduced end portion which is inserted into the other member.

Each of the wall frames further includes an upper member comprising a rectangular metal tube and a plurality of upper connecting members attached to the upper member and extending downwardly therefrom. Each of the upper connecting members also comprises a rectangular metal tube and is aligned with one of the lower connecting members. A plurality of upper joints interconnects the support members and the upper connecting members, with each of the upper joints interconnecting one of the support members and one of the upper connecting members. Each of the support members extends between one of the lower connecting members and the aligned one of the upper connecting members. For each of the upper joints, either the support member or the upper connecting member has a reduced end portion which is inserted into the other member. Similar to the previously discussed embodiment, the reduced end portion of each of the lower and upper joints is preferably formed by a roll reduction process.

At least one of the exterior wall frames may further include a window frame disposed between and interconnected to the base and the upper member. The window frame may be connected to the base via a second plurality of lower connecting members attached to the base and extending upwardly therefrom, a plurality of lower window frame connecting members attached to and extending downwardly from the window frame, and a second plurality of upwardly extending support members. Each one of the support members extends between and is connected to one of the second plurality of lower connecting members and an aligned one of the lower window frame connecting members. The joints between each support member and the corresponding one of the lower window frame connecting members and the second plurality of lower connecting member is preferably configured as described previously, i.e., a reduced end portion of one member is inserted into the corresponding adjacent member. The window frame may be connected to the upper member in a similar fashion.

The system may further include an interior wall frame attached to and extending inwardly from one of the exterior wall fires. The interior wall frame may include a base attached to the foundation of the structure, a plurality of lower connecting members attached to and extending upwardly from the base, an upper member spaced apart from the base and a plurality of upper connecting members attached to and extending downwardly from the upper member.

DETAILED DESCRIPTION

Referring now to the drawings, wherein like reference numerals have been used for similar elements throughout, FIG. 1 is an elevation view illustrating a framing system 10 , according to a first embodiment of the present invention. The framing system 10 may be used to frame either an exterior or an interior wall for a wide variety of structures including, but not limited to the following structures: residential homes; carports; commercial buildings such as office, retail, mini-storage and industrial buildings; apartment and condominium buildings; office build-out and commercial buildings; utility buildings; and modular/ kiosk structures. The framing system 10 may be attached to a concrete support structure 12 which may comprise a concrete slab or a portion of a poured concrete foundation. Alternatively, the framing system may be attached to other conventional foundation or support structures. As yet another alternative, in certain applications, the framing system may rest upon a ground surface.

The framing system 10 includes a base 14 , which is attached to the concrete support structure 12 by conventional means as subsequently discussed in greater detail. Base 14 is preferably made from either rectangular metal tubing or square metal tubing but may alternatively be made from other metal structures such as metal plates, metal channel sections, and angled metal sections. Additionally, base 14 may be made as either a unitary or one piece construction, or alternatively may be made from a plurality of the foregoing metal components, such as rectangular or square metal tubing, which are attached to one another. In the illustrative embodiments shown in FIGS. 1-8 , base 14 is made from a single section of rectangular metal tubing.

As used herein, the term “rectangular metal tubing” refers to hollow metal tubing having a substantially rectangular cross-sectional shape and the term “square metal tubing” refers to hollow metal tubing having a substantially square cross-sectional shape. The rectangular and square metal tubing incorporated in the various embodiments of the framing system of the present invention may be made of steel or aluminum or any other metal or metal alloy which is suitable for use in constructing a system for use in framing a wide variety of structures including, but not limited to those mentioned previously with respect to framing system 10 . It is a further requirement with respect to certain components of the various framing systems of the present invention which require an end reduction, that the metal selected to construct the component must be compatible with achieving the end reduction via a roll reduction process as disclosed in co-pending U.S. patent application Ser. No. 08/957,354.

Framing system 10 further includes a plurality of lower connecting members 16 which are preferably made from either rectangular or square metal tubing and are attached to the base 14 by conventional means, such as welding. As shown in FIG. 1 , the lower connecting members 16 are spaced apart from one another along base 14 , with the particular spacing depending upon the application of system 10 . For instance, if the framing system 10 is used to frame the wall of a residential structure, the lower connecting members 16 may be advantageously spaced either 16 or 24 inches from one another due to the common use of this spacing in wood framed residential structures. However, it should be understood that other spacings may be utilized in residential home applications.

The framing system 10 further includes a plurality of upwardly extending support members 18 , which may be referred to as studs depending upon the particular application of system 10 . Each of the support members 18 is made from either a rectangular metal tube or a square metal tube and is interconnected to one of the lower connecting members 16 via one of a plurality of lower joints 20 as discussed further in conjunction with FIG. 2 . The cross-sectional shape of each support member 18 must match the cross-sectional shape of the corresponding or interconnected one of the lower connecting members 16 . Accordingly, if a particular lower connecting member 16 is made from a rectangular metal tube, then the interconnected one of the support members 18 must also be made from a rectangular metal tube. Similarly, if a particular lower connecting member 16 is made from a square metal tube, then the interconnected one of the support members 18 must also be made from a square metal tube. The support members 18 extend upwardly from the lower connecting members 16 and, in one preferred embodiment, are substantially vertically extending.

In the illustrative embodiment, the framing system 10 further includes an upper member 22 which is made from at least one rectangular or square metal tube. In the illustrative embodiment, the upper member 22 is made from a single rectangular metal tube, but alternatively may be constructed from a plurality of rectangular metal tubes which may be attached to one another. In other embodiments, when the support members 18 are made from square metal tubes, the upper member 22 may be made from either a single square metal tube or a plurality of square metal tubes. In other embodiments the upper member 22 may be made of other metal components such as metal plates, metal channel sections, and angled metal sections.

System 10 further includes a plurality of upper connecting members 24 which are attached to and extend downwardly from the upper member 22 . The upper connecting members 24 are made from either rectangular or square metal tubes, with the chosen configuration depending upon the shape of the corresponding support member 18 and lower connecting member 16 . For instance, if both the corresponding lower connecting member 16 and support member 18 are made from rectangular metal tubing, then the upper connecting member 24 must also be made from rectangular metal tubing, as shown in FIG. 2 . The upper connecting members 24 are attached to the upper member 22 by conventional means, such as welding. Each of the support members 18 is interconnected to one of the upper connecting members 24 via one of a plurality of upper joints 26 . Each of the upper connecting members 24 is positioned on the upper member 22 so that it is aligned with one of the lower connecting members 16 . Each of the support members or studs 18 extends between one of the lower connecting members 16 and the aligned one of the upper connecting members 24 as shown in FIG. 1 .

As shown in FIG. 2 , each of the support members 18 includes a lower end portion 28 , an upper end portion 30 and an intermediate portion 32 which extends between and is integral with the lower 28 and upper 30 end portions. The lower 28 and upper 30 end portions and intermediate portion 32 are preferably made as a one-piece construction. As shown in FIG. 2 , the lower 28 and upper 30 end portions comprise reduced end portions of support member 18 and have a rectangular cross-sectional shape which is reduced in size relative to the rectangular cross-sectional shape of the intermediate portion 32 of the corresponding support member 18 .

The reduced, lower end portion 28 of each support member 18 is inserted into the corresponding lower connecting member 16 which has a rectangular cross-sectional shape which may be the same size as that of the intermediate portion 32 of the support member 18 . In this instance, the reduced, lower end portion 28 comprises the male portion of the corresponding lower joint 20 , while the lower connecting member 16 comprises the female portion of the corresponding lower joint 20 . The reduced end portion 28 and lower connecting member 16 are preferably sized so that they engage one another in a snug fit. Similarly, the reduced, upper end portion 30 of each support member 18 is inserted into the corresponding one of the upper connecting members 24 . Accordingly, the upper end portion 30 of each support member 18 comprises the male portion of the corresponding upper joint 26 , while the interconnected one of the upper connecting members 24 comprises the female portion of the corresponding joint 26 .

The reduced end portions 28 and 30 of each support member 18 are preferably formed by a process which may be referred to as a roll reduction process. As used herein, the term “roll reduction process” is intended to refer to reducing an end portion of either a square or rectangular metal tube by inserting the tube into a tool which incorporates a plurality of rollers which are configured and arranged to achieve the desired end reduction in the tube. More specifically, as used herein, the term “roll reduction process” is intended to refer to achieving the desired end reduction in either a square or rectangular metal tube by utilizing a tool such as tool 10 or tool 100 which are disclosed in co-pending U.S. patent application having Ser. No. 08/957,354 entitled “Tool for Working Shaped, Hollow Metal Tubing to Achieve an End Reduction”, which is expressly incorporated by reference herein in its entirety. As shown in application Ser. No. 08/957,354 an end reduction of a square metal tube may be achieved by using tool 10 , while an end reduction of a rectangular metal tube may be achieved by using tool 100 . For further information regarding the structural features of the tools disclosed and the manner in which an end reduction of a square or rectangular metal tube is achieved, the reader is referred to application Ser. No. 08/957,354.

Referring now to FIGS. 3 and 4 it may be seen that the longitudinal lengths of the lower connecting members 16 and the reduced, lower end portions 28 of the support members 18 may be sized to achieve somewhat different results. For instance, as shown in FIG. 3 , the longitudinal length of the lower end portion 28 is greater than that of the corresponding lower connecting member 16 so that the lower end portion 28 extends upwardly above the upper edge 34 of the corresponding lower connecting member 16 . As shown in FIGS. 3 and 4 , each of the support members 18 may include a lower tapered portion 36 , having a relatively small longitudinal length which forms a transition between the intermediate portion 32 and the reduced end portion 28 . As shown in FIG. 2 , each support member 18 further includes an upper, tapered portion 38 , which also has a relatively small longitudinal length, and forms a transition between the intermediate portion 32 and the reduced end portion 30 of member 18 .

The relative lengths of the lower connecting member 16 and the reduced end portion 28 shown in FIG. 3 may be desirable in certain applications so that any vertical load existing in the support member 18 is reacted at the interface between a lower edge 40 of support member 18 and base 14 . This configuration provides increased surface area to react the load carried by support member 18 as compared to the configuration shown in FIG. 4 , for the following reasons. The longitudinal length of the lower connecting member 16 shown in FIG. 4 is substantially the same as the longitudinal length of the reduced end portion 28 of support member 18 . Accordingly, a portion of the upper edge 34 of the lower connecting member 16 engages the tapered portion 36 of the support member 18 . The entire edge 34 may not contact the tapered portion 36 of member 18 due to the sloped surface of the tapered portion 36 . The configuration shown in FIG. 3 may be desirable in instances when the framing system 10 is used to frame a relatively heavily loaded wall, such as that which may be incorporated in a portion of a residential home, for instance. The configuration shown in FIG. 4 may be advantageously utilized when the corresponding support member 18 is subjected to a relatively smaller load.

As shown in FIGS. 3 and 4 , the base 14 may be attached to the foundation 12 by a plurality of concrete bolts 42 (one shown in FIGS. 3 and 4 ), with each bolt 42 being secured by a nut 44 . Alternatively, the base 14 may be attached, or secured to the foundation 12 by other conventional means, such as nails, screws, anchor bolts, or equivalent fasteners.

Each of the lower joints 20 may comprise a staked joint as shown in FIGS. 3 and 5 . In this instance, a local indentation 46 is formed in the lower connecting member 16 and a complimentary, local indentation 48 is formed in the lower end portion 28 of the corresponding one of the support members 18 so that the support member 18 and lower connecting member 16 are staked or secured to one another. Alternatively, for one or more of the lower joints 20 , the support member 18 and the corresponding lower connecting member 16 may be fastened to one another by conventional fasteners such as bolts or sheet metal screws. As yet another alternative, support members 18 may be secured to the corresponding lower connecting members 16 using nails or pins. Similarly, each of the upper joints may comprise a staked joint, with complimentary local indentations formed in the reduced upper end portion 30 and the corresponding one of the upper connecting members 24 . Alternatively, the reduced upper end portion 30 of the support member 18 may be fastened or pinned to the corresponding upper connecting member 24 , for one or more of the upper joints 26 .

FIG. 6 is fragmentary, perspective view illustrating a portion of a framing system 50 according to a second embodiment of the present invention.

The support members 194 may be configured with reduced upper and lower end portions as shown with respect to support member 18 and therefore, may be interconnected to the upper connecting members 24 and the header connecting members 192 as shown in FIG. 2 with respect to members 16 , 18 and 24 . Alternatively, other configurations of rectangular metal tubing, such as the upper and lower connecting members and the support members shown in FIGS. 6-8 may be used to interconnect the door header 188 and garage door header 190 with the upper member 176 . However, as stated previously, the use of square metal tubing as shown in FIG. 9 is not presently preferred in residential home applications. This may change in the future due to changes in the construction industry and therefore the use of square metal tubing to construct interconnected components of framing system 140 is considered to be within the scope of the present invention.

Referring now to FIG. 13 , the side wall frame 144 is illustrated and discussed in further detail. The wall frame 144 further includes an upper member 196 and a plurality of the upper connecting members 24 attached to the upper member 196 by conventional means such as welding and extending downwardly therefrom.

Base 214 similarly includes first 222 , second 224 , and third 226 portions, with each comprising a rectangular metal tube in the illustrative embodiment. However, portions 222 , 224 and 226 may alternatively be made of square metal tubing or the alternative metal structures listed previously with respect to base 212 . Each of the base portions 216 - 222 of bases 212 and 214 is attached to a foundation 229 of the carport in the illustrative embodiment by conventional means such as a plurality of nails 231 as further illustrated in FIG. 18 . In other embodiments the framing system 210 may rest on a ground surface. The framing system 210 farther includes a first plurality of lower connecting members 228 which are attached to the base 212 by conventional means such as welding, and extend upwardly therefrom. Framing system 210 further includes a second plurality of lower connecting members 228 attached to the base 214 in a similar manner. Each of the lower connecting members 228 includes a lower portion 230 which is attached to the corresponding one of bases 212 and 214 , and an upper portion 232 which has a reduced cross-sectional size relative to the lower portion 230 . The reduction in size of the upper portion 232 is preferably accomplished by the roll reduction process discussed previously. The framing system 210 further includes a plurality of first side posts 234 , with each having a substantially straight portion 236 and an arcuate portion 238 integral with an upper end of the substantially straight portion 236 . The reduced end portion 232 of each one of the lower connecting members 228 is inserted into a lower end 240 of the substantially straight portion 236 of one of the first side posts 234 .

The framing system 210 further includes a plurality of second side posts 242 which are preferably identical in construction to the side posts 234 . Each of the second side posts 242 includes a substantially straight portion 244 and an upper, arcuate portion 246 which is integral with the substantially straight portion 244 . The reduced end portion of each one of the second plurality of lower connecting members 228 is inserted into a lower end 248 of the substantially straight portion 244 of one of the second side posts 242 . The interconnected members may be further secured by one or more bolts 249 or alternatively the second side posts 242 may be staked to the corresponding lower connecting member 228 . The first side posts 234 may be similarly connected to the lower connecting members 228 .

As shown in FIGS. 16 and 17 , each of the first side posts 234 is aligned with one of the second side posts 242 and is interconnected to the aligned one of the second side posts 242 by a bridge member 250 . Each of the bridge members 250 includes a pair of rafters 252 and a peak 254 in the illustrative embodiment. Each of the rafters 252 has a first end portion 256 , an intermediate portion 258 and a second end portion 260 . The end portions 256 and 260 have a reduced cross-sectional size relative to that of the intermediate portion 258 , with the reduced end portions 256 and 258 of rafters 252 preferably being formed by the roll reduction process discussed previously. The end portion 256 of a first one of the rafters 252 of each bridge member 254 is inserted into the arcuate portion 238 of the corresponding one of the first side posts 234 . The reduced end portion 256 of the second rafter 252 of each bridge member 250 is inserted into the arcuate portion 246 of the aligned second side post 242 . The ends 260 of each of the pair of rafters is then inserted into opposite ends of the corresponding peak 254 .

Each of the following components of the framing system 210 preferably comprises a rectangular metal tube and even more preferably comprises a rectangular metal tube having a cross-section which has outside dimensions of 1½ inches×3½ inches: base portions 216 - 222 ; lower connecting members 228 ; first 234 and second 242 side posts; rafters 252 and peaks 254 .

Each bridge member 250 may alternatively comprise a unitary construction or as another alternative, may be constructed of fewer or greater components provided the same overall shape of each bridge member 250 is substantially retained. Furthermore, the configurations of the ends of selected components of the flaming system 210 may be varied to achieve the same results. For instance, each of the lower connecting members 228 may comprise a substantially uniformly shaped rectangular tube, with the lower ends 236 and 248 of the first 234 and second 242 side posts comprising reduced end portions which are inserted into the corresponding lower connecting members 228 .

The arcuate portions of the first 234 and second 242 side posts, as well as peaks 254 is achieved by bending the corresponding rectangular metal tubes and provides the advantage of eliminating mitered joints which might otherwise be required.

While the foregoing description has set forth the preferred embodiments of the present invention in particular detail, it must be understood that numerous modifications, substitutions and changes can be undertaken without departing from the true spirit and scope of the present invention as defined by the ensuing claims. For instance, while the reduced end portions of the rectangular or square metal tubes included in the various embodiments of the present invention are preferably formed by the roll reduction process disclosed in co-pending U.S. patent application Ser.
