INTRODUCTION We thank you for purchasing the “A” AnchorSpan™ clearspan fabric structure from Anchor Industries Inc. The AnchorSpan™ is designed to provide a balance between ease of installation and the aesthetic appeal of the curved beam structural configuration. This assembly manual is for all A AnchorSpans™, including 30’, 40’, 50’, 60’, 70’ and 80’ wide units. We recognize that every installation site is unique with its own individual obstacles and requirements.
“A” ANCHORSPAN™ INSTALLATION SAFETY GUIDELINES Your own installation techniques will evolve to fit the varied needs of your clients, the experience level of your installation crews, the nature of other tentage that may be common to the installation site, and the equipment that you may have previously available or with which you feel most comfortable. Whatever techniques you adapt for your crews, we encourage you to keep safety utmost in mind.
EQUIPMENT AND LABOR RECOMMENDATIONS FOR MANUAL INSTALLATION Labor: (See Appendix, page X-4) AnchorSpans™ from 60’ wide to 80’ wide can be manually installed safely and efficiently by a crew of (8 to 10) laborers using the tools recommended from the AA AnchorSpan. However, because the “A” beam extends all the way to 80’ wide, we are recommending the use of power equipment. With careful planning, depending on personnel, you will develope your own techniques.

At each joint, male ends point toward the apex. 4 5 Apex 3 6 Short Rafter 2 7 Long Rafter 80’ BEAM ASSEMBLY Base Column 8 1 Pin to baseplate, using the “A” bent arm pin (bent arm to outside) Swing wide to assemble then reposition and pin to baseplate Beam Assembly: Note: Beams are shipped from the factory with splices pre-installed in base columns and rafters.
BEAM ASSEMBLY COMPLETE Continue assembling beams until all are completed flat on the ground, as above. Install SpanLatch Purlins and Cross-Cabling: On all but the first end beam to be raised, bolt the fixed ends of SpanLatch purlins to the top of the 2” round purlin spacer at each apex joint and each base column joint. For the 80’ span, see #2, 3, 4, 5, 6, and 7 (in drawing on Page 10).
Erecting Beams using the Fork Lift Method (NOTE: For an alternate method using a Gin Pole method, see the AA AnchorSpoan Assembly Manual and increase the number of workers pulling the beam, or reaplace them with appropriate powered equipment.) In order to pivot the beams to a vertical position, you must pull the beam from a vertical angle. This vertical angle can be provided by a forklift, cherry picker, crane, or any other suitable substitute.
First beam standing with diagonal brace installed Diagonal Brace Safety Lines Diagonal Braces Installed Erecting the 2nd Beam. Erect the 2nd beam the same as above, except that the beam harness hooks to the top hole in the fixed end of the apex purlin. And, instead of diagonal beam braces, the 2nd beam is stabilized by connecting its SpanLatch™ purlins to the first beam (See top of Pg 14). Using the purlin hook, push the SpanLatch™ end of each purlin to the top of the beam a few feet above each joint.
Engage SpanLatch Purlins between 1st & 2nd beam Push SpanLatch above joint, then hook and pull purlin downward onto Purlin Spacer to engage and latch. Use short purlin tool on low purlins, long purlin tool on high purlins Safety Lines Prevent Beam from falling toward forklift. 2nd beam pivoted same as 1st, but secured by SpanLatch Purlins, rather that diagonal brace.

Installation of Middle Panels 2nd beam pivoted same as 1st, but secured by SpanLatch Purlins, rather that diagonal brace. Clip rope to fabric panel WIND SpanLatch Purlins Rope to workers for pulling 2 workers to feed fabric into channels 2 to 4 workers for pull ropes Middle panels between beams (ready for installation) Do not tension the middle panel until the middle eave bars have been installed in its bay and the adjacent middle panel has also been installed.
Tensioning of Middle Panels Insert web tail through spindle. Ratchet handle up & down to tension fabric Tuck kedar tail downward into outer beam channel Tensioning of Middle Panels: (See Above) 1. Tuck the fabric tails of each panel downward into the beam channel flare until all middle panel kedar rests within the outer beam channel. 2. Install (2) fabric tensioning winches with hooks into each baseplate, as shown. 3.
Installation of 2-pc Gabled End Panel (See bottom of Page 17) 1. Install Gabled End panel into Lower Beam Channel (same as liner channel) on the outer facing surfaces of the first and/or last beam. 2. Because the flared opening in the liner channel is approximately 9’-6” feet high, a small step ladder will be useful in feeding the gabled end fabric into the beam channel. 3. With workers positioned as shown (page 17) feed half of the 2-pc.
Install End Uprights: (See Bottom of Page 18) One worker stands on base of upright at ground level, while second worker walks the top of the upright to vertical. Align the T-fitting at the top of upright with the slot of the upright bracket on the underside of the beam. Lift upright until T-fitting enters the slot, then rotate the upright 90 degrees with offset to the inside (as shown). (Do not anchor the uprights until after the eave bars and ground bars have been installed.
Tensioning of Gabled End Panel: (If you are installing a 40’,50’ or 80’ “A” Span, see appendix page “X-3” on end center bars before tensioning the gabled end.) For 30’, 60’ & 70’ spans, proceed as follows: 1. Tension the gabled end using a standard ratchet hooked into baseplate adapter bar at each side of the structure. Tension each side evenly, so as not to draw the gabled end panel off center (See the peak of the beam). Tension until the kidder bottoms out against the baseplate.
ANCHORSPAN™ WALL SYSTEMS (with Loop & Grommet Lacing) Top loop passes up and over the mid eave bar connector. 2nd loop passes through 1st grommet, then interweaves with top loop. continue with loop and grommet lacing.
Middle Wall Installation ( See “A” and “B” on preceding page.) Standard vinyl middle walls are 2-piece with loop and grommet lacing down the center line of the wall. Sunburst window walls are also 2-piece but the lace line is along the beam, not down the center line. Midwalls are interchangeable on all A and AA AnchorSpans™ with 15’ beam spacing. 1.

GUIDELINES FOR DISASSEMBLY Fabric: Walls -- Remove Ground Bars; Unlace the 2-pc wall; slide hooks out of eave bar channel, and pull kedar up and out of liner channels of beam and outer channels of end uprights. Gabled Ends -- Release tension by jamming ratchet handles to full vertical position and removing the web at the end uprights and at the beam baseplates. Release caribiners at top and bottom of lace line (use safety line if climbing on top of structure).
