## Abstract

An extrudable keder rail and a clamping anchor for the keder rail are cooperative to secure keder fabric to a building support beam. The clamping anchor allows the keder rail to be securely attached to a standard beam without drilling holes or strapping about the beam. A temporary clamp and movable tensioning device allow the keder rails and keder fabric to be applied to the building support beams after the support beams have been assembled and installed.

## Claims

### Claim 1

In combination, a keder rail, support beam and keder rail attachment, said keder rail comprising:
a base;
two longitudinally open bodies each having one open slit extending in the longitudinal direction; and
a longitudinally extensive slot between said two longitudinally open bodies;
said keder rail attachment comprising:
a fastener affixed laterally through said keder rail base; and
couplers extending between said fastener and said support beam;
wherein said couplers further comprise two securing angles that each are distally located about said support beam.

### Claim 2 (depends on 1)

The combination keder rail, support beam and keder rail attachment of claim 1, wherein said base further comprises a rectangular hollow extrusion.

### Claim 3 (depends on 1)

The combination keder rail, support beam and keder rail attachment of claim 1, wherein said two longitudinally open bodies further comprise longitudinal cylinders.

### Claim 4 (depends on 1)

The combination keder rail, support beam and keder rail attachment of claim 1, wherein said fastener passes through each of said two securing angles, and may be tightened thereabout to secure to said support beam.

### Claim 5 (depends on 1)

The combination keder rail, support beam and keder rail attachment of claim 1, wherein said support beam further comprises an I-beam.

### Claim 6 (depends on 5)

The combination keder rail, support beam and keder rail attachment of claim 5, wherein said support beam further comprises a plurality of slots formed in said I-beam through which a tensioning anchor tongue may operatively be received.
