Keder rail attachment for a fabric/panel building
View Patent ↗An keder rail and clamping anchor secure keder fabric to a building support beam. In one embodiment, the clamping anchor clamps about the support beam. In a second embodiment, the anchor passes through the support beam and compresses a pair of laterally extending keder rail feet against the support beam. A temporary keder rail anchor has a transitional member, support beam engagement, and keder rail engagement that displace and hold the second embodiment keder rail to an offset position relative to support beam prior to and during installation of keder fabric within the keder rail. A method of tensioning keder fabric uses this holder to secure the keder rail adjacent an edge of the structural beam while keder fabric is inserted. The holder is released and the keder rail is centered on the beam to tension the keder fabric, and the keder rail is secured to the structural beam.
1. A keder rail anchor operative with a generally planar top surface of a support I-beam and a keder rail and configured to support said keder rail in a position to receive flaccid keder fabric, said keder rail anchor comprising:
a generally planar support beam engagement configured to engage on a major surface with said support I-beam generally planar top surface;
a keder rail engagement distal and perpendicular to said support beam engagement;
a first fastener configured to retain said support beam engagement to said support I-beam;
a second fastener configured to retain said keder rail engagement to said keder rail; and
a transitional member between and coupled with said support beam engagement and said keder rail engagement rising out of a plane defined by said generally planar support beam engagement and configured to terminate adjacent to and above a keder rail anchor foot, said transitional member, said support beam engagement, and said keder rail engagement configured to anchor said keder rail on and adjacent to an edge of said support I-beam generally planar top surface.
2. The keder rail anchor of claim 1 , wherein said keder rail engagement comprises a generally planar member perpendicular to said support beam engagement.
3. The keder rail anchor of claim 2 , wherein said keder rail anchor comprises a formed metal strap.
4. The keder rail anchor of claim 2 , wherein said keder rail anchor further comprises an L-shaped geometry.
5. A keder rail anchor operative with a support I-beam and a keder rail and configured to support said keder rail in a position to receive flaccid keder fabric, said keder rail anchor comprising:
a support beam engagement configured to engage with a first lateral half of a support I-beam generally planar top surface;
a keder rail engagement adjacent to a lateral edge of said support I-beam generally planar top surface distal to said first lateral half, said keder rail engagement generally perpendicular to said support I-beam generally planar top surface;
a first fastener configured to retain said support beam engagement to said support I-beam;
a second fastener configured to retain said keder rail engagement to said keder rail; and
a transitional member between and coupled with said support beam engagement and said keder rail engagement in contact with said support I-beam generally planar top surface adjacent to said support beam engagement and rising away from said support I-beam generally planar top surface adjacent to said keder rail engagement;
said transitional member, said support beam engagement, and said keder rail engagement configured to anchor said keder rail on a second half of said support I-beam generally planar top surface in a position offset from and distal to a longitudinal center line that divides said support I-beam generally planar top surface into said first and second lateral halves.
6. The keder rail anchor of claim 5 , wherein said support beam engagement comprises a generally planar member, and said keder rail engagement comprises a generally planar member perpendicular to said support beam engagement.
7. The keder rail anchor of claim 6 , wherein said keder rail anchor comprises an L-shaped geometry.
8. The keder rail anchor of claim 7 , wherein said keder rail anchor comprises a formed metal strap.
