Description

FIELD OF INVENTION

The present application relates to a girt or purlin retainer. More particularly, the application relates to a compressible girt or purlin retainer.

BACKGROUND

Building frames having girt clips and/or purlin clips are known in the art. Generally, a building frame consists of horizontally spaced-apart metal, wood, or polymer frame members. Purlins span between primary framing and a supporting roof material and are “Z” or “C”-shaped members formed from sheet metal, a polymeric sheet material, or wood. Girts span between the frame members to support wall material and are typically “Z” or “C”-shaped members formed from sheet metal, a polymeric sheet material, or wood. Each of the frame members normally has a plurality of vertically-spaced clips secured thereto which extend substantially horizontally to support the girts. Inasmuch as the length of the girts are typically less than the length of the building, the girts are often overlapped and secured together.

In another alternative embodiment, the second retainer 110 b may be hammered onto the connecting member or cross-beam.
FIG. 3 illustrates a perspective view of one embodiment of an exemplary retainer 110. As can be seen in the illustrated embodiment, the retainer 110 has a U-shaped profile that includes a first leg 210, a second leg 220, and a connecting portion 230 joining the first leg 210 and the second leg 220. In the illustrated embodiment, the first and second legs 210, 220 are both L-shaped, having a major length and a minor length. The retainer 110 further includes a plurality of teeth 310. In the illustrated embodiment, the teeth 310 are V-shaped teeth stamped in the retainer 110 and bent inwards. In other words, the teeth 310 of the first leg 210 are bent towards the second leg 220, and are therefore configured to engage a first surface of a cross-beam (not shown) or connecting member (not shown). Further, the teeth 310 of the second leg 220 are bent towards the first leg 210 and are therefore configured to engage a second surface of a cross-beam or connecting member. In the illustrated embodiment, the teeth 310 are smooth. In an alternative embodiment (not shown), the teeth have serrated edges. In other alternative embodiments (not shown), the teeth may have a W-shape, a right-triangle-shape, or any other shape having at least one point. In another alternative embodiment (not shown), one or more of the teeth may be replaced with adhesive, rubber strips, or other known engaging or gripping elements.
In this embodiment, when the retainer 110 is squeezed onto the connecting member or cross-beam, the teeth 310 engage and retain the connecting member or cross-beam. In the illustrated embodiment, the retainer 110 has six teeth on the first leg 210 and six teeth on the second leg 220. It should be understood that more or fewer teeth may be employed as desired.
FIG. 4 illustrates a top view of one embodiment of a girt or purlin retaining assembly 100 retaining a first cross-beam C₁and a second cross-beam C₂, and connected to a support member S. As can be seen in the illustrated embodiment, the first retainer 110 a is substantially L-shaped having a major length and a minor length. The first retainer 110 a includes a first beam engaging portion 410 a configured to receive and retain a first cross-beam C₁, such as a girt or a purlin. In the illustrated embodiment, the first beam engaging portion 410 a is the major length of the L-shaped retainer. The first retainer 110 a further includes a first connecting member engaging portion 420 a configured to engage the connecting member 120. In the illustrated embodiment, the connecting member 120 is a block. Therefore, for convenience, the first connecting member engaging portion 420 a may be referred to as a first block engaging portion 420 a. However, this term should not be read as limiting, and it should be understood that the connecting member 120 is not limited to having a block shape nor is the block engaging portion 420 a limited to engaging a block-shaped connecting member. In the illustrated embodiment, the first block engaging portion 420 a is the minor length of the L-shaped retainer.
In the illustrated embodiment, the first retainer 110 a includes a taper 430 a between the first beam engaging portion 410 a and the first block engaging portion 420 a. The tapered shape reduces the amount of material used in the first retainer 110 a and provides clearance to ease installation of the crossbeam on a support member (not shown).
With continued reference to FIG. 4, the second retainer 110 b is also substantially L-shaped. The second retainer 110 b includes a second beam engaging portion 410 b configured to receive and retain a second cross-beam C₂, such as a girt or a purlin. In the illustrated embodiment, the second beam engaging portion 410 b is the major length of the L-shaped retainer. The second retainer 110 b further includes a second connecting member engaging portion 420 b configured to engage the connecting member 120. The second connecting member engaging portion 420 b may also be referred to as a second block engaging portion 420 b. However, this term should not be read as limiting, and it should be understood that the connecting member 120 is not limited to having a block shape nor is the block engaging portion 420 b limited to engaging a block-shaped connecting member. In the illustrated embodiment, the second block engaging portion 420 b is the minor length of the L-shaped retainer.
In the illustrated embodiment, the second retainer 110 b includes a taper 430 b between the second beam engaging portion 410 b and the second block engaging portion 420 b. The tapered shape reduces the amount of material used in the second retainer 110 b and provides clearance to ease installation of the crossbeam on a support member (not shown).
In the embodiment illustrated in FIG. 4, the connecting member 120 and the first and second cross-beams C₁, C₂extend beyond the first and second retainers 110 a,b by a distance d. The distance d is selected by a user assembling the girt or purlin retaining assembly 100. In an alternative, such as shown in FIG. 1, the, the connecting member 120 and the first and second cross-beams C₁, C₂are flush with the first and second retainers 110 a,b.
In one embodiment, the first and second retainers 110 a,b and the support member S are constructed of steel, other metal, or another high thermal conductivity material. In this embodiment, the connecting member 120 and the first and second cross-beams C₁, C₂are constructed of wood, a polymer, or other material having a low thermal conductivity. In other words, the connecting member 120 and the first and second cross-beams C₁, C₂are low thermal conductivity members. In the illustrated embodiment, the connecting member 120 and the first and second cross-beams C₁, C₂extend beyond the first and second retainers 110 a,b, thereby preventing the first and second retainers 110 a,b from contacting a wall. Instead, the connecting member 120 acts as a thermal break between a wall and the first and second retainers 110 a,b, thereby, reducing the flow of heat between a building interior and exterior.
In an alternative embodiment, the connecting member 120 and the first and second cross-beams C₁, C₂are constructed steel, other metal, or another high thermal conductivity material and the connecting member 120 does not act as a thermal break.
FIG. 5 illustrates an alternative embodiment of a girt retaining assembly 500 for attaching first and second cross-beams C₁, C₂to a corner support member S_c. In the illustrated embodiment, the girt retaining assembly 500 includes a first retainer 510 a configured to be attached to the first cross-beam C₁and a second retainer (not show—hidden from view) configured to be attached to the second cross-beam C₂. The first retainer 510 a is further configured to be attached to a first connecting member 520 a, shown here as a block. The first connecting member 520 a is configured to be attached to the corner support member S_caccording to one of the methods of attaching described above.
With continued reference to FIG. 5, the second retainer (not shown) is further configured to be attached to a second connecting member 520 b, shown here as a block. The second connecting member 520 b is configured to be attached to the corner support member S_caccording to one of the methods of attaching described above.
As can be seen in the illustrated embodiment, the girt retaining assembly 500 is aligned with the corner support member S_csuch that the first cross-beam C₁is substantially perpendicular to the corner support member S_cand is substantially parallel to the ground. Further, second cross-beam C₂is aligned substantially perpendicularly to the corner support member S_cand is also aligned substantially perpendicularly to the cross-beam C₁. In alternative embodiments, the girt retaining assembly 500 may be attached to the corner support member S_cat any desired angle.
FIG. 6 illustrates a perspective view of an alternative embodiment of a girt or purlin retainer 600 having a first leg 610 and a second leg 620. In this embodiment, the retainer 600 includes two distinct members rather than a unitary member having a connecting portion. In the illustrated embodiment, the first and second legs 610, 620 have substantially the same profile as the first and second retainers 110 a,b described above in relation to FIG. 3. In the illustrated embodiment, the retainer 600 includes a plurality of teeth 630, similar to the teeth described above with respect to FIG. 3. It should be understood that the first and second legs 610, 620 can be squeezed onto both a cross-beam (not shown) and a connecting member (not shown). In one embodiment, the retainer 600 is configured to be squeezed by hand onto the connecting member and the cross-beam. In an alternative embodiment, the retainer 600 is configured to be squeezed onto the connecting member and cross-beam with a vice, a hand tool such as pliers, pincers, vice grips, or other known tools. In another alternative embodiment, the retainer 600 may be hammered onto the connecting member and cross-beam.
FIG. 7 illustrates a perspective view of another alternative embodiment of a girt or purlin retainer 700. In this embodiment, the retainer 700 includes a first leg 710 having a first extension 720 and a second leg 730 having a second extension 740. The first and second legs 710, 730 are joined by a torsion spring 750 configured to bias the first leg 710 towards the second leg 730. A user may separate the first leg 710 from the second leg 730 by squeezing the first and second extensions 720, 740 towards each other. The retainer 700 further includes a plurality of teeth 760, similar to the teeth described above with respect to FIG. 3. A user may attach the retainer 700 to a cross-beam (not shown) or a connecting member (not shown) by squeezing the first and second extensions 720, 740, placing a cross-beam or connecting member between the first and second legs 710, 730, aligning the cross-beam or connecting member with the appropriate teeth 760, and releasing the first and second extensions 720, 740.
FIGS. 8-13 illustrate exemplary profiles of alternative assemblies for retaining a girt or purlin. It should be understood that these profiles may be employed for any of the retainers 110 a,b, 600, 700 described in relation to FIGS. 1-7 above.
FIG. 8 illustrates a profile 800 that is substantially similar to the profiles illustrated above in FIGS. 1-7. In this embodiment, the profile 800 is substantially L-shaped, with a taper 810, and has a plurality of teeth 820.
FIG. 9 illustrates a profile 900 that is substantially similar to the profile 800 illustrated in FIG. 8. However, in this embodiment, the profile 900 includes a larger block engaging portion 910 configured to engage a larger connecting member (not shown).
FIG. 10 illustrates a substantially U-shaped profile 1000. The U-shaped profile 1000 may be used for a unitary retainer for engaging a connecting member and cross-beam (not shown) instead of using two separate retainers.
FIG. 11 illustrates an L-shaped profile 1100 that is substantially similar to the profile 800 illustrated in FIG. 8, except it lacks a taper. An L-shaped profile without a taper may be easier to manufacture.
FIG. 12 illustrates an L-shaped profile 1200 that is substantially similar to the profile 800 illustrated in FIG. 8, except it includes apertures 1210 instead of teeth. The apertures are configured to receive fasteners (not shown). In one embodiment, the apertures 1210 are threaded and configured to receive a screw, bolt, threaded rod, or other such threaded fastener. In an alternative embodiment, the apertures 1210 are smooth and configured to receive pins, ties, nails, rivets, or other such smooth fasteners. It should be understood that a retainer may include both teeth, such as those illustrated in FIGS. 2-3 and apertures 1210, so that the retaining plate may be attached to the cross-beam (not shown) and connecting member (not shown) in several different ways simultaneously. It should be further understood that apertures may be used in place of teeth in any of the above described profiles.
FIG. 13 illustrates an L-shaped profile 1300 that is substantially similar to the profile 1200 illustrated in FIG. 12, except that instead of simple apertures, the profile employs positive fastener angling apertures 1310. The positive fastener angling apertures 1310 guide a fastener (not shown) diagonally. By using such apertures, a user is able to drive a fastener through both a cross-beam (not shown) and into the support member (not shown), or through both a connecting member (not shown) and into the support member (not shown).
It should be understood that a retainer may include any combination of teeth, such as those illustrated in FIGS. 2-3, apertures 1210, such as those illustrated in FIG. 12, and positive fastener angling apertures 1310, so that the retaining plate may be attached to the cross-beam (not shown) and connecting member (not shown) in several different ways simultaneously. It should be further understood that any combination of teeth, apertures, and positive fastener angling apertures may be used in any of the above described profiles.
FIG. 14 illustrates a detail perspective view of the positive fastener angling apertures 1310 of FIG. 13. In the illustrated embodiment, the profile 1300 includes a slit-cut 1410 and guideway means 1420 formed from the deformed material of the profile 1300 in the general shape of one half of a cone having a curved wall. In this configuration, when a fastener F is driven into the profile 1300, the guideway means guides the fastener F diagonally. It should be understood that the fastener F may be any one of a screw, bolt, threaded rod, pin, tie, nail, rivet, or other known fastener.
To the extent that the term “includes” or “including” is used in the specification or the claims, it is intended to be inclusive in a manner similar to the term “comprising” as that term is interpreted when employed as a transitional word in a claim. Furthermore, to the extent that the term “or” is employed (e.g., A or B) it is intended to mean “A or B or both.” When the applicants intend to indicate “only A or B but not both” then the term “only A or B but not both” will be employed. Thus, use of the term “or” herein is the inclusive, and not the exclusive use. See, Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2d. Ed. 1995). Also, to the extent that the terms “in” or “into” are used in the specification or the claims, it is intended to additionally mean “on” or “onto.” Furthermore, to the extent the term “connect” is used in the specification or claims, it is intended to mean not only “directly connected to,” but also “indirectly connected to” such as connected through another component or components.
While the present application illustrates various embodiments, and while these embodiments have been described in some detail, it is not the intention of the applicant to restrict or in any way limit the scope of the claimed invention to such detail. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the application, in its broader aspects, is not limited to the specific details, the representative apparatus, and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the applicant's claimed invention.
