Definitions
- ABSTRACT OF THE DISCLOSURE A truss having wooden chord members and metallic web or strut members therebetween having apertured load transfer end flanges abutting the chord members, said end flanges being secured to the chord members by overlying toothed connector plates of larger area than the end flanges, all of the teeth of said connector plates being embedded in said chord members, and a plurality of said teeth extending through and abuttingly intermeshing with the apertures in said end flanges to maintain said flanges against lateral movement relative to said connector plates.
- the present invention relates generally to trusses. More particularly, the present invention relates to a combination of wooden and metallic members conjoined as a truss. Specifically, the present invention relates to a novel truss of combined wooden chord members and improved metallic web connectors.
- Trusses are used a great deal in building construction for the support of roofs providing long, clear spans and frequently for supporting floors.
- wooden trusses predominated over their metallic counterparts. This was understandable inasmuch as wood was extremely plentiful and modestly priced.
- skilled carpenters were available to assemble the wooden trusses on the job at low cost.
- prefabricated trusses found favor, but for a long time prefabricated metal trusses found more favor than prefabricated wooden trussesparticularly because they were more readily adapted to mechanical fabrication techniques and because they provide an excellent strength to weight ratio.
- metallic truss connector plates one example of which is shown in my United States Patent No.
- chord members are wooden so that no separate nailing strips need be applied and in which the web members are metallic.
- a truss having upper and lower wooden chord members in one plane with metal strut portions extending between the chord members and having perforate flat transfer end flanges abutting the sides of the chord members, said flanges being connected to said chord members by toothed connector plates of larger area which overlie said flanges, all of the teeth being embedded in said chord members, and some of said teeth passing through said perforate transfer flanges.

- FIG. 15 is a cross section taken substantially on line 1515 of FIG. 14.
- chord members The members which form the outline or perimeter of a truss are generally called the chord members, or simply chords.
- the interior members connecting between the chords are called the web members, or, commonly, the diagonals or verticals, depending upon their direction in the Web system.
- an exterior type connector plate is used to connect wooden structural members that are joined in abutting relation and a sandwich type connector plate is used to connect wooden structural members that are joined in overlapping relation.
- the concept of the present invention employs either type connector plate.
- a truss constructed according to the concept of the present invention utilizes wooden chord members and metallic web members.
- the metallic web members not only supply the normal function of resisting the tensile and compressive forces between chord members but also, as web connectors, impart the necessary unity to the truss.
- Each web connector has a strut portion extending between the chord members and a load transfer flange at each end of the strut portion.
- the load transfer flanges are secured to the chord members by tooth means such as exterior connector plates.
- the load transfer flange has a plurality of apertures through which at least a portion of the teeth on a connector plate are insertably received.
- the connector plate teeth abuttingly intermesh with the side walls of the apertures so that the load transfer flange not only lies snugly between the body portion of the connector plate and the wooden chord member in which the connector plate teeth are embedded but also is maintained against lateral movement with respect to both the body portion of the connector plate and the chord member.
- a truss constructed according to the concept of the present invention may utilize chord members consisting of, parallel, adjacent wooden structural members.
- a sandwich connector plate is readily utilized.
- a combination truss according to the present invention is designated generally by the numeral in FIG. 1.
- the upper chord member 11 and lower chord member 12 are generally parallel and interconnected with diagonal web connectors 13A, 13B, 13C to present a general Warren truss arrangement supported between bearing walls 14 and 15.
- a Warren truss arrangement has been disclosed, it should be understood that those skilled in the art will be readily able to adapt the present concept to a host of truss configurations.
- the chord members 11 and 12 are of wood, and the web connectors 13A, 13B are of metal. As best seen in FIGS. 2-6, the web connectors 13 each have a strut portion 16, each end of which terminates in a load transfer flange 18 and 19. Typical examples of suitable web connectors 13 are depicted in FIGS. 4 and 5.
- the strut portion 16 is depicted as being of channel-shaped across section with the load transfer flange 18 being, in part, an extension of the base 20 of the channel-shaped section.
- the legs 21 and 22 of strut portion 16 may be formed, through transitional contortions 23 and 24, respectively, to lie in the same plane as the base 20 at the ends of the web connector 13 and thereby complete the load transfer flange 18.
- FIG. 5 Another form of web connector 113, as disclosed in FIG. 5, also has a strut portion 116 but it is of tubular cross section, and the ends are simply flattened to form the load transfer flange 118.
- the load transfer flange will be provided with a plurality of perforations, or apertures, 25.
- the exact shape of the apertures 25 is not critical so long as they intermesh with the teeth means sufl'iciently to maintain the load transfer flange 18 fixed with respect to the chord member to which it is secured.
- the tooth means is preferably a toothed exterior connector plate, such as is indicated generally by the numeral 26.
- the exact configuration of the connector plate 26 is not critical, but a construction which performs extremely Well has a plurality of teeth 28 which are struck, or punched, from the body portion 29 of the plate in opposed pairs.
- each tooth 28 has a thickness generally equal to the thickness of the plate because it was struck therefrom, and, as best seen in FIGS. 9 and 10, each tooth has a base portion 30 the edges 31 and 32 of which are generally parallel and extend generally perpendicularly outwardly from the body portion 29 of the plate 26.
- Each tooth also has a tip portion 33 of lesser width than the base portion 30 which is formed integrally outwardly thereof with one edge 31A being preferably a continuation of the edge 31 of base portion 30.
- the opposite edge 34 of the tip portion 33 is preferably parallel to edges 31 and 31A but is spaced more closely thereto than the corresponding edge 32 of the base portion 30.
- the edges 32 and 34 are joined by an inclined transitional shoulder 35.
- the preferred proportions of this tooth can also best be seen in FIGS. 9 and 10.
- the width of the base portion 30 is approximatly one-third the length of the tooth 28,
- the length of the base portion 30 is approximately one-half the length of the tooth.
- the length of the base portion includes the length of the transitional shoulder 35 which is approximately one-sixth the length of the tooth, and the width of the tip portion 33 is approximately onehalf the width of the base portion 30.
- the base portion 30 would be approximately of an inch wide and V of an inch long, of which the transitional shoulder 35 would extend approximately i of an inch.
- the width of the tip portion 33 would also be approximately of an inch.
- teeth are preferably punched in pairs from openings 36 which are longitudinally aligned and laterally staggered so that lateral alignment occurs between alternate rows.
- the die by which the teeth are punched causes the opposed teeth 28A and 28B in each pair to separate along a cleavage line 38 (FIG. 11) inclined to the axis 39 of the longitudinal alignment of the openings 36 so that the teeth present a point 40 at the outermost extent of the tip portion 33.
- the metal tends to draw as it separates along cleavage line 38, thus sharpening the tip of the tooth.
- the punching die also bends each tooth so that there is a slight rearward arching of each tooth about its base portion 30 so that the tip portion 33 is inclined away from the opening 36 from which the tooth was struck in the direction of their longitudinal alignment.
- the punching die also crimps, or dishes, each tooth 28 so that the outer surface 41 of the base portion 30' is generally arcuate.
- the dishing is along a crimp line 42 which is slightly inclined with respect to the outwardly extending direction of the tooth so that the tooth is contorted into a gentle twist about the crimp line 42. It has been found desirable to incline the crimp line toward the side 31A of the tooth 28A on one side of opening 36 (FIG. 9) and toward the transitional shoulder 35 of the tooth 283 on the other side of opening 36 (FIG. 10) so that the teeth will be complementarily twisted as can be seen in FIG. 4.
- Teeth having the particular configuration described above have been found to possess superb holding power and easy insertability and yet can be economically produced.
- the exact shape of the apertures 25 is not critical so long as the position of the load transfer flange 18 is maintained with respect to the chord member and the connector plate 26.
- the aperture could be constructed so that the abutment of the side walls of the apertures with the edges 31 and 32 of the base portion 30 of each tooth maintains the flange 18 against movement laterally of the longitudinal alignment of opening 36.
- the outer arcuate surfaces 41 of the base portion 30 on opposed teeth 28A and 28B can abut the opposed end walls of the apertures so as to maintain the load transfer flange 18 against movement parallel to the longitudinal alignment of openings 31.
- the load transfer flange 18 it is not necessary for the load transfer flange 18 to be coextensive with the connector plate 26.
- the connector plate 26 was found to develop between 350 to 400 pounds of holding power per square inch of plate area.
- the load transfer flange 18 could be loaded as high as 1000 pounds per square inch of perforated area in contact with the connector plate without initiating premature failure in the holding power of the teeth 28 or destruction of the wooden member.
- the use of a load transfer flange 18 having approximately three-eighths the area of the connector plate 26 has been found to be quite satisfactory in distributing the stress in the web connector 13 to the chord members 11 or 12.
- the wooden member is thereby armored both to provide greater resistance against crushing and to increase the horizontal shear strength thereof.
- the holding power of the teeth 28 which intermeshingly engage the apertures 25 has been found to be increased over those which directly penetrate the wood-the flange 1'8 apparently reinforcing the teeth against bending and thereby increasing their holding power.
- web connectors 13 embodying the concept of the present invention may economically be placed as needed.
- a truss designed in accordance with that shown in FIG. 1 to support a uniform load it is well known that the diagonal web members adjacent the bearing walls 14 and 15 are subjected to the greatest stress, the stress on the diagonal web member successively toward the center of the truss span being less and less.
- the engineer computing the design for such a truss may require that two web connectors 13A and 13A be used for the first diagonal but one be used for the diagonals more remote from the support.
- chord members 11 and 12 be doublers rather than a single member of deeper cross section.
- Such a combination truss 110 is shown in FIGS. 12-15.
- the lower chord member 112 is comprised of two wooden members 112A and 112B positioned in parallel, side-by-side relation.
- the exemplary web connectors 113A and 113B depicted may both be anchored between the chord members 112A and 112B by a single sandwich type connector plate 126, best seen in FIGS. 14 and 15, with the flange 118A lying on one side of body portion 129 and the flange 118B lying on the other side.
- the pattern in which the teeth extend outwardly from one side or the other of the plate may be countlessly varied to produce a sandwich type connector plate, convenience suggests that the pattern be such that any web connector 113 be capable of being attached to either side of body portion 129 without the use of excessive apertures through the load transfer flange 118.
- One very effective tooth pattern results by having the openings 136 from which the teeth 128 are punched aligned both longitudinally and laterally.
- the individual teeth 128 may be of exactly the same configuration as the teeth 28 on the exterior plate 26 and may also be punched as opposed pairs from a single opening. With such an arrangement the teeth may be punched from laterally adjacent rows to extend alternately from one or the other side of the body portion 129, the teeth punched from the openings in any longitudinal row extending from only one side of the body portion 129.
- Apertures 125 need, therefore, only to be provided for intermeshing with teeth 128 punched from every other longitudinal row of openings 136 and the web connector 113 may be secured by placing the load transfer flange 118 on either side of the body portion 129 with the strut portion 116 diagonally oriented either to the left or to the right of the location of the load transfer flange 118.
- doubler chord members such as 112
- additional sandwich plates 126 between the location of the load transfer flanges to assure further integrity of the members 112A and 112B into a single working member.
- additional web connectors 13 mounted with exterior connector plates 26 in those locations where the web members are subjected to the greatest stress, as is shown in the variation depicted in FIGS. 1 and 2.
- a combination truss comprising wooden chord members and metallic web connectors, said web connectors each having a strut portion extending between said chord members and a load transfer flange at each end of said strut portion abutting the chord members, tooth means connecting said load transfer flange portions to said chord members, at least one of said chord members comprising parallel, side-by-side, wooden members, and the tooth means comprising a toothed sandwich connector plate between said chord members having a plurality of teeth extending outwardly in opposite directions into said side-by-side chord members, at least a portion of the teeth extending in one direction passing through the apertures in the load transfer flange.
- a combination truss as set forth in claim 1, in which at least two web connectors are secured to said parallel wooden members by one said sandwich connector plate.
- a combination truss as set forth in claim 2, in Which the apertures through the load transfer flange for one of said web connectors are abuttingly intermeshed with at least a portion of the teeth on one side of said sandwich connector plate and the apertures through the load transfer flange on the other web connector are abuttingly intermeshed with at least a portion of the teeth on the other side of said sandwich connector plate.
- a combination truss as set forth in claim 3, in which the apertures through the load transfer flange on each web connection and the teeth on each side of said sandwich connector plate are oriented in a pattern whereby said load transfer flanges can he secured by the teeth on either side of said connector plate body portion.
- a combination truss as set forth in claim 3, in which sandwich connector plates in addition to those securing web connectors are used to unify the parallel wooden chord members.
- a combination truss comprising wooden chord members and web connectors, at least selected web members carrying tensile loads having a metallic strut portion and metallic load transfer flanges at the ends contacting the chord members and having a plurality of apertures, and toothed connector plates overlying said load transfer flanges and having a plurality of teeth extending through said apertures into said chord members, the toothed area of said connector plates being greater than the area of said load transfer flanges.
