F055 United States Patent O rifice 3,410,583 STRUCTURAL SHAPE CGNNECTOR John S. Frye, 3698 Trafalgar, Chamblee, Ga. 30005, and James B. Fuss, 3245 Enon Road, College Park, Ga. 30022 Filed Dec. 22, 1966, Ser. No. 605,144 4 Claims. (Cl. 287-48935) ABSTRACT F THE DISCLGSURE A structural shape connector of the type utilized to connect the joist of a oor to the sill. The connector is formed of two parts that are placed in side by side relationship, includes flanges that grip a corresponding groove in the sill structure, and a sloped, upwardly extending stem which is connectable to the web of an I-beam joist. A resilient fastener attaches the connector to the sill and floor joist. The fastener is constructed of spring steel and defines a hexagonal through bore and external threads so that it can ybe threaded into an aperture defined in a structural shape from the remote side of the shape.
In building construction, it is common practice to place floor or ceiling joists on the upper surface of a sill or similar structural shape so that the wei-ght of the floor is transmitted downwardly through the joist onto the upper surface of the sill. Since most of the force exerted from the oor is exerted downwardly from the oor, through the joist to the sill, the forces exerted by the joists to the sill are primarily compressive forces. In ceiling construction, the sill structure also primarily encounters compressive forces from the joists; however, forces exerted on the sides of the building by wind, and expansion and contraction of the building cause some working movement of the structural supports of the building so that some sliding or shearing or twisting motion lbetween the building support elements is encountered. Thus, it is desirable to have the joists connected to the sill or other support structure in such a manner that relative movement therebetween is resisted. However, since the primary force encountered between these elements is primarily compressive force, the connection between these elements to resist the remaining forces need not be as strong.
Accordingly, it is an object of this invention to provide a structural shape connector for connecting joists and the like to sills which resists relative movement between these elements.
Another object of this invention is to provide a connector having interlocking parts for interconnection between the sill and joist elements of a building.
Another object of this invention is to provide a connector for the sill and joist elements of a building wherein the movement of the joist with regard to the sill is resisted.
Another object of this invention is to provide a fastener for connecting structural shapes together, wherein the fastener is resilient and compensates for the movement between the structural shapes.
Another object of this invention is to provide a convenient, economical and firm connection between a joist and its support surface in a building. i
Other objects, features and advantages of the present invention will become apparent upon reading the following specification, taken in conjunction with the accompanying drawing, in which:
FIG. 1 is a perspective view of the structural shape connector, showing the manner in which floor joists are connected to the sill structure;
FIG, 2 is a perspective view of the internal bracket of the connector;
3,410,588 Patented Nov. 12, 1968 FIG. 3 is an elevational view, in cross section, of the connector;
FIG. 4 is an elevational view, in cross section, of the fastener utilized with the connector.
FIG. 5 is a bottom view of the fastener of FIG. 4.
Referring now more particularly to the drawing, in which like numerals indicate like parts throughout the several views, FIG. l shows a channel -beam 1t) having a base 11 and a pair of downwardly extending sides 12 and 13. External grooves 14 and 15 are dened in sides 12 and 13, adjacent base 11, and extend longitudinally of the exterior surface of beam 10. Base 11 is apertured at 16, at spaced intervals along its length. Channel beam may be supported in any manner in the building construction in order to function as a sill or similar support piece.
An Iabeam is positioned so that it rests on the upper surface of Ibase 11 of the channel beam 10. I-beam 20 includes a central web 21 and upper and lower flanges 22 and 23. I-beam 2t) is positioned so that it extends in a horizontal plane, in a direction disposed substantially at right angles to the direction in which the channel beam 1i? extends. Near the end of I-beam 20 central web 21 defines an aperture 24 of a diameter substantially equal to the diameter of the apertures 16 in the channel beam 10.
Connector 25 extends between channel beam 10 and I-beam 20 and connects these elements to each other. Connector 25 comprises a pair of brackets, internal bracket 26 and external bracket 27. Internal bracket 26 includes a substantially flat base portion 29, a downwardly extending clip and an upwardly extending stem 31. Base portion 29 is generally rectangular in configuration, and clip 30 includes a downwardly extending leg 32 extending integrally from one edge of the base portion 29, and an inwardly turned tab 33 folded back toward and extending in a plane parallel to base portion 29. Base portion 29 defines an aperture 35 in its central portion, the diameter of which is substantially equal to the diameter of the apertures 16 of channel beam 10. A locking tab 36 is struck upwardly from the base portion 29 of internal bracket 26, to one side of aperture 35. Locking tab 36 includes a backwardly extending projection 37.
As is best shown in FIG. 4, fasteners 62 are provided to connect the brackets 26 and 27 to each other and to channel beam and I-beam 20. Fastener 62 is fabricated of spring steel, or similar resilient material, and comprises a tubular, sleeve-like body portion 64. An annular, outwardly extending fiange 65 extends about one end of the body portion 64, and an annular, inwardly extending ange 66 extends about the opposite end of body portion 64. The outer perimeter of flange 65 is generally circular, and the inner perimeter of flange 66 defines a hexagonal opening 67 as shown in FIG. 5. The outer surface of body pornnn 64 is threaded with conventional helical screw threads of approximately four threads -per turn. Body portion 64 is slightly tapered inwardly from fiange 65 toward fiange 66.
OPERATION When it is desired to connect lJbea-rns to channel beams, as when connecting elements orf this configuration to form joists of a floor or ceiling, the I-beams are positioned with their lower fianges 23 resting on the base 11 of a channel beam 10. Connectors 2S are connected to channel beam 10, adjacent each one of the I-beams 20. Connectors 25 are connected to channel beam 10` by first placing the lower surface of the base portion 29 of the internal bracket 26 in juxtaposition with the upper surface of base 11 of channel beam 10. This positions tab 33 of the internal bracket 26 into groove 15 of channel beam 10. External `bracket 27 is then fitted over internal bracket 26 by allowing locking tab 36 o'f internal bracket 26 to slide through locking slot 56 of the external bracket 27. This places base portion 29 of external bracket 27 in juxtaposition with base portion 29 of the internal bracket 26. External bracket 27 is then moved in a lateral direction with respect to channel beam 10 so that its tab 53 engages groove 14 of the channel beam. Locking slot 56 is of sufficient width so as to accommodate this movement. External bracket 27 is then moved in a longitudinal direction as indicated by arrow 57 so as to align its central aperture 55 with that of internal bracket 26. Thus, backwardly extending projection 37 of internal bracket 27 projects over the edge of locking slot 56 of the external bracket so that internal and external brackets 26 and 27 are positively held together and onto base 11 of channel beam 10, and no pivotal movement or inadvertent motion of brackets 26 and 27 will func-tion to allow these brackets to separate.
When internal and external brackets 26 and 27 are aligned, as previously described, their stems 31 and 51 are placed in immediate juxtaposition, as is shown in FIG. 1, and their apertures 41 and 61 are aligned with each other. Of course, stem 51 of external bracket 27 is slightly smaller in its overall dimensions than stem 31 of internal bracket 26 so as to allow this mating of surfaces and apertures, while downwardly extending leg 52 of external bracket 27 is longer than downwardly extending leg 32 of internal bracket 26 to compensate for the additional thickness of the base portion 29 of internal bracket 26 being positioned between base portion 49 of external bracket 27 and channel beam 10.
After connector 25 has been assembled in this manner, the apertures 35 and 55 of base portions 29 and 49 are aligned with one of the apertures 16 of channel beam 10 and a fastener 62 is threadedly engaged within the aligned apertures. Fastener 62 is rotatably urged into the aligned apertures, and the threads thereof engage the internal perimeters of the aligned apertures so as to pull the fastener 62 into the apertures.
After connector 25 is attached to channel beam 10, the I-bearn 20 which is in its vicinity is moved toward the mated stems 31 and 51 so that aperture 24 of the central web 21 of the I-beam is aligned with the mated apertures 41 and 61 of stems 31 and 51. Since sloped portions 39 and 59 of stems 31 and 51 slope upwardly and outwardly of the base portions 29 and 49 of the brackets, the connecting portions 40 and 60 of stems 31 and 51 will be adjacent the central web 21 of I-beam 20. Thus, the leg of the lower flange 23 of I-beam 20 will extend below sloped portions 39 and 59 of stems 31 and S1, as is shown in FIGS. 1 and 3. A fastener 62 is inserted through the aligned apertures 61, 41 and 24 of the brackets and i-bearn.
It is anticipated that the channel beam 10, I-beam 20, connector 27 and fastener 62 may be fabricated of any number of metals; however, it is anticipated that the most practical combination of these elements would be with the channel beam, I-beam and connector being fabricated of aluminum and the fastener 62 being fabricated of spring steel. With this combination of materials, the threads of the fasteners 62 would function to dig into the inner perimeter of the aligned apertures of the connector and its adjacent beam. Also, the resiliency of the spring steel fastener would be such that if the apertures of the elements were not perfectly aligned, the fastener, being deformable, could compensate for the misali-gnment. Furthermore, after the beams have been connected to each other as disclosed, any working or relative movement between the beams, such as expansion and contraction of the building or slight movement of the building due to wind pressure, will be compensated for by the resiliency of the fastener 62 without any appreciable loosening of or damage to the beams or connector 25. Thus, it can be seen that connector 25 functions -to expediently interconnect the beams of a building while the fastener 62 functions to allow slight movement of the beams with each other. Also, the configuration of the clips 30 and 50 of brackets 26 and 27 prevent any significant lateral movement of I beams 20 with channel beam 10.
It will be obvious to those skilled in the art that many variations may be made in the embodiments chosen for the pur-pose of illustrating the present invention without departing from the scope thereof as defined by the appended claims.
