In various embodiments, the fabric panel attachment system includes a keder rail fastened to support bar, which is attached to a structural profile, such as a building frame member. In some embodiments, the keder rail is fastened to a support bar with bolt and nut. One or more fabric panels are installed within channels of the keder rail. An alignment element may be used with a fastener to assist in aligning abutting sections of keder rail. In various embodiments, the fabric panel attachment system is secured to flat or curvilinear faces of the structural elements. In some embodiments, the fabric panel attachment system may secure directly to the structural element and not a support bar. ## Claims ### Claim 1 A system for attaching fabric panels to a structure, the system comprising: a support fixed to a structural profile associated with the structure, wherein the support extends transversely from a surface of the structural profile; a first keder rail including at least one elongated keder channel and a first mounting arm, wherein the first mounting arm comprises a mounting face adapted to operatively engage the support, the first mounting arm further comprising at least one mounting aperture that penetrates the mounting face; one or more fasteners sized to extend through the at least one mounting aperture and the support to secure the first mounting arm and the structural profile with one another, whereby the one or more fasteners are selectively adjustable in a manner that draws the first mounting arm and support toward one another from a slackened position, whereby the first mounting arm and support are spaced-apart from one another, to a tensioned position, whereby the first mounting arm and support are positioned against one another; a second keder rail comprising a second mounting arm; a first alignment channel operatively coupled with the first mounting arm, wherein the first alignment channel has an elongated opening in a side parallel to a length of the first keder rail; a second alignment channel operatively coupled with the second mounting arm, wherein the second alignment channel is open along its side; and an alignment element configured to be positioned in the first alignment channel and the second alignment channel to align the first keder rail with the second keder rail. ### Claim 2 (depends on 1) The system of claim 1 wherein: the first mounting arm is generally planar and extends transversely from a bottom surface of the first keder rail. ### Claim 3 (depends on 1) The system of claim 1 wherein: the support is generally planar and the surface of the structural profile is an upper surface of the structural profile. ### Claim 4 (depends on 1) The system of claim 1 wherein: a distal end portion of the first mounting arm is chamfered to provide a space between the first mounting arm and the support; the space being shaped to accommodate a weld bead or debris that may be located between the first mounting arm and the support. ### Claim 5 (depends on 1) The system of claim 1 further comprising: a spacer that coaxially surrounds at least one of the one or more fasteners and prevents the first mounting arm and the support from advancing to the tensioned position with one another, maintaining the first mounting arm and support in a slackened position. ### Claim 6 (depends on 1) The system of claim 1 further comprising: an elongated, depressed channel operatively coupled with the first mounting arm; the depressed channel being in open communication with the at least one mounting aperture and shaped to receive a fastener element in a secure position that resists rotational movement of the fastener element. ### Claim 7 (depends on 6) The system of claim 6 wherein: the one or more fasteners include threaded bolts, and the fastener element is a nut configured to threadably receive one of the threaded bolts. ### Claim 8 (depends on 1) The system of claim 1, further comprising an additional fastener positioned in the elongated opening of the first alignment channel. ### Claim 9 (depends on 1) The system of claim 1 wherein, in the tensioned position, heads of the one or more fasteners abut the support. ### Claim 10 (depends on 1) The system of claim 1, wherein the at least one elongated keder channel comprises two elongated keder channels. ### Claim 11 A system for attaching fabric panels to a structure, the system comprising: a support fixed to a structural profile associated with the structure, wherein the support extends transversely from a surface of the structural profile; a keder rail including at least one elongated keder channel and a mounting arm, wherein the mounting arm comprises a mounting face adapted to operatively engage the support, the mounting arm further comprising at least one mounting aperture that penetrates the mounting face; one or more fasteners sized to extend through the at least one mounting aperture and the support to secure the mounting arm and the structural profile with one another, whereby the one or more fasteners are selectively adjustable in a manner that draws the mounting arm and support toward one another from a slackened position, whereby the mounting arm and support are spaced-apart from one another, to a tensioned position, whereby the mounting arm and support are positioned against one another; and a depressed channel operatively coupled with the mounting arm, wherein the depressed channel is elongated along an axis parallel to the keder channel, the depressed channel is in open communication with the at least one mounting aperture, and the depressed channel is shaped to receive a fastener element in a secure position that resists rotational movement of the fastener element. ### Claim 12 (depends on 11) The system of claim 11, wherein the at least one elongated keder channel comprises two elongated keder channels. ### Claim 13 A system for attaching fabric panels to a structure, the system comprising: a support fixed to a structural profile associated with the structure, wherein the support extends transversely from a surface of the structural profile; a keder rail including two elongated keder channels and a mounting arm, wherein the mounting arm comprises a mounting face adapted to operatively engage the support, the mounting arm further comprising at least one mounting aperture that penetrates the mounting face; one or more fasteners sized to extend through the at least one mounting aperture and the support to secure the mounting arm and the structural profile with one another, whereby the one or more fasteners are selectively adjustable in a manner that draws the mounting arm and support toward one another from a slackened position, whereby the mounting arm and support are spaced-apart from one another, to a tensioned position, whereby the mounting arm and support are positioned against one another.
