dur-o-wal, dur-o-flex friction pin anchor - cmi pins - dur-o-wal.pdf · 4-2 dur-o-flex friction pin...

A suitable anchor for wall tying in applications that typical-ly would use masonry connectors of the light to mediumduty variety.

Dur-O-Flex is a non-corrosive masonry anchoring systemuniquely designed to withstand axial loading, and provideflexible within-plane wythe movement. The Dur-O-Flexanchor concept can be used in either restoration or new

construction involving masonry anchoring applications.The Dur-O-Flex is attached to a structure via friction usingsimple installation methods, or bonded with epoxies tocreate the most flexible wall tie in its class. The Dur-O-Flexanchor rectangular cross section has been engineered intoa continuous spiral shape with broad bearing surfaceedges that distributes forces over a large area.

• One step installation. • Lower installed cost.

• Manufactured of austentic steel type 304. • Provides outstanding corrosion protection for most allaggressive corrosion environments.

• Helical design. • Creates a threading action during installation thatensures a friction fit for quality performance.

• Broad bearing surface edges. • Optimized steel contact area with base material whichminimizes stress—no sharp edges.

• No axial stiffening rib. • Provides in-plane ductility which allows for nonconcur-rent wythe movement of masonry.

• Flexible. • Absorbs energy from veneer movement within-plane andlessens the chance of the anchor to “walk” out of thehole.

• Engineered drilled hole sizes. • Provides the maximum amount of surface contact areain hard or soft anchoring materials.

• One piece anchor. • No multiple components assembly required.

• Simplified installation equipment. • Requires little training with easy installation methods.

• Can be field trimmed to length. • Allows for easy adaptation to common field variations ofdepth.

• Anchorage performance enhancement possible withoutsacrificing flexibility.

• Optional epoxy bonded connections obtain great holdingpower in base materials which are soft or fragile.Flexibility is maintained via the Dur-O-Flex design.

• Optional resin bonded connections can be quality testedindependently for the back up anchor and veneer anchorconnections.

• Provides a quality assurance method no other epoxy pinconnection is capable of this qualification.

DUR-O-FLEX FRICTION PIN AND ANCHORWhen evaluating the application of a friction pin anchoringsystem, the following anchoring features should be evalu-ated:

A) Performance Repeatability: All dry fix or friction pinconnectors are subject to base material consistency.Similar to a nails performance in various substrates,the dry fix connection relies on intimate contact withits base material. The connection forces are distributedat the circumferential contact points of its spiral shape.Performance repeatability will then be a function ofbase material density, hole size, friction coefficients ofthe base material, uniformity of base material qualities,and base material elasticity.

B) Quality Control: On site quality control testing is possi-ble but limited to veneer, or outermost connectionsonly. Tension testing of the back up, or verifying a backup connection has occurred, is only possible if non-contact veneer anchoring exists. That can be accom-plished by drilling an oversize hole (1/2") thru theveneer, then switch to the appropriate back-up hole forthe pin installation in the back up. Also, the veneerconnection can be disengaged (cored out) to isolatethe back up for testing. However, this would only indi-cate what was available for the subject specimen, andcannot be assumed for all pins installed.

C) Live Loads: As a dry fix, or friction pin connector, per-formance results are a function of base material quali-ty, thickness and density. Good results in solid materi-als are typically achieved. Ultimate pullout capacitiesgreater than 250 pounds are possible in most all build-ing material. This satisfies many moderate wind loadperformance criteria in non-essential structures andlow rise buildings.

D) Installation Ease: By far, the friction pin anchoringsystem is the easiest retrofit system available. Oncethe pilot hole has been properly drilled, the anchorinstalls in seconds by using a quality rotary hammerand the S.D.S. adapted setting tool. The setting charac-teristics of threading and insertion is accomplished bythe anchor’s spiral design and the hammer drivingaction of the tool. The chisel pointed end, which is fac-tory produced, provides the leading end a directionalpath to anchor into the substrate.

E) Installed Cost: The fact that the Dur-O-Flex Friction Pininstallation technique is among the quickest reanchor-ing systems available, contributes significantly to theanchor’s installed cost. Also, Dur-O-Wal’s effort todevelop a durable, low cost, installation tool, combinedwith a competitively priced anchor, makes this systema cost effective solution for pinning. Total time to installa Dur-O-Flex Friction Pin can be less than 60 seconds.

F) In-Plant Ductility: By virtue of the Dur-O-Flex design,in plane flexibility is greater than most standardmasonry wall ties. This is especially important to con-sider for significant deflection caused by expansion andcontraction cycles. Dur-O-Flex’s spring like design is anideal solution for anchoring insulated cavity walls withinsufficient ties.

G) Facade Aesthetics: The friction pin anchor requireshole sizes of approximately 1/4". The anchor, onceinstalled, is recessed in the veneer by approximately1/4-3/8". The installer needs only to plug a small holewith mortar since the joint is a preferred location. Notethat thru brick installations are very difficult to main-tain in a water tight condition. However, a sealant canbe used to match the color.

H) Veneer Seismic Retrofit: Currently, adaptations to theDur-O-Flex are not available to accommodate 9 gaugewire reinforcement. However, when used in new con-struction, the wire can be tied to the Dur-O-Flex forengagement purposes, thus meeting code.
