GENERAL INFORMATION1. A qualified person must accurately calculate the applied loads

and select the appropriate form tying products and determinecompatible tie spacings.

2. In form tying operations, proper installation practices must bemaintained. Failure to follow approved practices, such as missingform ties, misalignment of form ties, incorrect form tie lengths, excessive pour rates, etc., can cause form failure.

3. NCA recommends the user of the information contained hereinand the installer of our products adhere to the CanadianStandards Association CAN /CSA - S269.3 -M92 Concrete Formworkand American Concrete Institute -ACI 347 Guide to Formwork.The applied safety factor for a product will depend on the degreeof hazard or risk involved in the product application. This safetyfactor is governed by national codes, local codes and / or by designprofessionals. With regards to concrete construction, onsite conditions such as, poor concrete placing technique, concentratedloads on the formwork, improper use of cranes or concrete pumping could increase the degree of risk. If such site conditionsexist, the user must increase the safety factor to compensate. For most applications NCA suggests a minimum 2:1 safety factorfor hanging accessories and stresses that this safety factor shouldbe strictly adhered to or the application be reviewed by a design professional. The material included in this publication uses this 2:1safety factor for convenience but also provides the ultimate capacities so other safety factors may be used where applicable.

WARNING : Improper, careless and/or haphazard use of the products shown in this document can expose workers to extremedanger, injury and death. If uncertain about installations or use of any NCA product, contact the nearest NCA Sales office orTechnical Department for explanations and/or recommendations.

National Concrete Accessories products are manufactured according to strict specifications and are subject to numerous testsunder a stringent quality control program. These products aredesigned to be capable of meeting or exceeding all necessary safety requirements for the concrete construction and formingindustry. All product test data shown, were obtained through anindependent testing facility or tests conducted by NCA. However,the performance of a quality product can be affected by the manner in which it is used in the field. Therefore, the followingprecautions should be taken by all involved persons.

4. To avoid crushed wales and/or bent Tyholders when using a double waler system, maintain a spacing between the walers comparable to the tie diameter being used plus 13 mm (1/2").

5. Any welding required on a forming project should be performedby a certified welder. Bending or welding of high tensile steelproducts should not be permitted.

The information contained herein supersedes all previousversions printed priorto this edition and isbased on data andknowledge consideredtrue and accurate.NCA reserves the rightto update informationwithout notice.

Please read all statements, recommendations or suggestions in conjunction with NCA's condition of sale which apply to all goods supplied byNCA. No statement, recommendations or suggestions isintended for any usethat would infringe any patent or copyright.

Note: NCA does not warrant any product that has been welded,altered or modified in any way after leaving an NCA plant orwarehouse.

After final inspection of location and alignment, telltale devicesshould be installed in strategic places on the formwork to facilitate detection of formwork movement during concrete placement.

During concreting, the formwork should be continuously monitored by competent persons. These monitors should have a reasonable area of safety and a means of communicating problems or emergencies to the placement crew.

6. Never exceed listed product safe working loads. Note that allproduct load ratings shown in this bulletin are ratings for new or"as new" products only. Extreme caution must be exercised whenusing any product that is in other than new condition. Anyreusable product that shows wear, misuse, overloading, corrosionor any other factor that would compromise its safe working loadshould be discarded.

7. Caution must be exercised when using washer devices to spandouble wales. Waler gaps are excessive when the washer devicedoes not bear directly on the primary waler members.

8. NCA products are not to be applied or installed until the userand/or the installer has a clear understanding of the informationcontained within the appropriate product publication. All contractors must instruct their employees in the appropriate useand installation of NCA products.

To avoid injury and possible form tie problems DO NOT CLIMB ONFORM TIES.

Over-vibration or re-vibration will cause lower concrete to remainin a liquid state for an extended period of time. This can causeexcessive lateral form pressure and possible form failure

Plumbing of the form, after concrete placement, should not beattempted. It is virtually impossible to force a form back into posi-tion if it is misaligned or has bulged during concrete placement.

Runways for moving equipment should be provided with struts orlegs as required and be supported directly on the formwork orstructural member. Formwork must be suitable to support suchrunways without intolerable deflection, vibration or lateral movement.

9. Do not interchange products supplied by other manufacturerswith those supplied by NCA. NCA cannot guarantee that productssupplied by others will be compatible and/or interchangeable withNCA's quality concrete accessories.

10.Drawings and/or sketches shown in this bulletin are for illustrative purposes only. Check actual forming conditions forspecific applications. Metric values listed are a soft conversion ofimperial values.

NOTE: For applications notspecifically identified herein,approval in writing is required by the NCA TechnicalDepartment for specialapplications and uses of NCAproducts.

NCA Snap-Tys are fabricated to fit either prefabricated panels orbuilt-in-place forms. They are specifically designed for quick, easy andaccurate erection of light formwork. End sizes can be as short as 32mm (1¼") for Steel Washer Snap-Tys or as long as you need them tofit a special condition. Snap-Tys can be fabricated for any requiredwall thickness up to 6 m (19'-6") in length. Spreader washers areprecisely located to give exact wall thicknesses. Break points arelocated at specified distances back from the wall face to permit cleanstripping without spalling. All standard Tys are manufactured toprovide set back from the wall face. The small Ty holes and washerindentations are easily pointed, grouted or plugged. Consult theTechnical Department for minimum wall thicknesses. For exposedconcrete or where a longer set back is required, the NCA Space-TyTM issuggested.

Snap-Tys are stocked in 120 mm or 211 mm (4¾" or 8½") ends forstandard wall thicknesses.

10 kN (2,250 lbs) Snap-Tys areavailable in stainless steel uponrequest.

CAM-LOCK andANCHOR-LOCK

FORMING SYSTEMS

Cam-Lock Forming SystemThe NCA Cam-Lock Forming System takes advantage ofinexpensive forming materials, S4S 2x4s with 4'x8'x¾" or 2'x8'x¾"plywood sheets. When used for built-in-place forming, no ribbing orspecial hardware attached to the panels is necessary. The use of stiff-backs and walers is cut in half. Walers may be used either vertically orhorizontally, but field tests have proved the latter method to beeasier and faster.

The Cam-Lock Bracket holds the 2x4 waler in place by locking to theloop-end ty through caming pressure. Further rigidity of the formmay be obtained through use of the Cam-Lock Stiff-Back Cam whichconnects to the ears on the back of the Cam-Lock Bracket, lockingeither a 2x4 or 2x6 in place with the same caming principle. This alsoassures perfect alignment of the form from top to bottom andenhances the system’s adaptability to extremely high, close tolerancework.

The extreme rigidity of Cam-Lock Forming System makes it adaptableto all types of construction, and this same rigidity, coupled with theCam-Lock Scaffold Bracket, makes it especially desirable for high wallforming. Economy of the system is realized in labour costs throughthe simplicity of the system as well as the increased man-hourproduction that result from easier handling of the light weightplywood sheets. Since only half as much dimension lumber is used,further savings are derived from lower material costs.

The NCA Cam-Lock Self Centering D-Cone Ty features a highdensity polyethylene Cone Washer. This Cone Washer will not absorbmoisture or stick to the concrete, preventing break back problems. A smooth, uniform hole results after break back, allowing easiergrouting and faster, better finishing. The standard 25 mm (1")D-Cone comes with a 25 mm (1") break back. Self-centering taperedcones require a drill hole size of 21 mm (13/16").

Not to be used above 6.0 m (20'-0"). Any scaffolding above six metres (twenty feet) should be checked withlocal, provincial code requirements.

DON’Ts

• Never use the Scaffold Bracket with a short 2x4. Always use full length 2x4s that extend to a solid base.

• Never use the Scaffold Bracket with only one scaffold plank. • Always use two approved 2x12 scaffold planks side by side.

DOs

• The vertical 2x4 stiff-back must always extend to a solid base — the concrete footing, a floor slab or to compacted soil.

• The Scaffold Bracket must be attached to the second cam-lock form. Never attach the Scaffold Bracket to the top row of cam-lock brackets and form ties.

• A 2x4 stiff-back cam must always be attached directly below the Scaffold Brackets.

• A second 2x4 stiff-back cam must be attached directly below the Scaffold Bracket.

• Add an additional stiff-back cam at the bottom of the vertical 2x4 stiff-back to stabilize it.

• Scaffold Brackets are to be used on 6’ centers along the form with two 2 x 12” scaffold planks.

• A 42” guardrail with a 2x4 toeplate, mid-rail and top rail must also be used.

Since we cannot aniticpate every problem that may arise on the job in conjunction with the use of our product, we urge you to work safely and refer to your manuals for proper construction of concrete wall forming and scaffolding procedures.

The NCA Tyscru is an extra strong, resistance welded Ty designed totake the abuse encountered in medium and heavy concreteconstruction. An extremely simple Ty, capable of many combinationsand uses in the field, it may be used with or without Tycones orcombined with Continuous Threaded Lagstud to form an AdjustableTyscru.

Determining your Tyscru Requirement

Tyscru: The Tyscru length is determined by subtracting each set backrequirement from the wall thickness at the tie location. Lagstud orlagstud bolt length is determined by adding the form thickness to theset back on one side plus the Tyscru coil length plus 13 mm (½").Lagstud or Lagstud Bolt are furnished standard in even 50 mm (2")lengths. Select the next higher full unit over actual lengthdetermined. For extreme adjustment requirements, 25 mm to 50 mm(1" to 2") may be added.

2:1 Safety Factor

Wall thickness: Distance between the form facings at the Tyscrulocation.

Set Back: Required distance of Ty metal from the finished concreteface with or without the use of Tycones. Set back may be required atone or both faces, usually both. Total set back is the sum of set backsfrom both wall faces. When Tycones are used, their length is equal tothe required set back.

Form Thickness: Distance measured between the finished concretesurface to the outside face of the flat washer — includes plywoodsheeting material, studs, wales and washer.

Coil Penetration: Distance the Lagstud should penetrate the Tyscrucoil length plus 13 mm (½").

General instructions: For extreme penetration or extendedconcrete curing requirements, the Lagstud or Lagstud Bolt is normallygreased to facilitate removal. To break the bond and permit easyremoval, it is a good practice to turn the lagstud or lagstud bolt aquarter to one-half turn, in and out, eight to twelve hours after theconcrete has been poured.

The minimum Lagstud Bolt length required is equal to the sum of theflat washer, waler studs, form ply, set back and the coil length plus 13mm (½").

NCA suggests a minimum safety factor of 2:1. On site conditions such as, poor concrete,placing technique, concentrated loads on the formwork, improper use of cranes or concretepumping could increase the risk. If such site conditions exist, the user must increase the safetyfactor to compensate.

For anchoring situations not associated with forming, industry practice is to apply a safetyfactor of 4:1 minimum. For applications of greater risk a larger safety factor may be selected.

For edge distance and load reductions contact NCA technical representative.Specifications subject to change without notice.

NCA Bowlag Anchors provide an effective and efficient She-Boltreanchorage for cantilever and Ty back lift forms. The continuous lagthread and the bow shape provide good anchorage even in greenconcrete and consistently outperforms smooth crimped rods and/orpigtails. The lag thread engagement is quick to install or disconnect.The bow shape prevents loosening during vibration and resistsrotating or spinning during stripping.

The NCA Screw Anchor Bolt System provides a permanent ortemporary cast in place anchorage. The Screw Anchor embedded inconcrete effectively distributes bolt loads into the surroundingconcrete. The Screw Anchor Bolts are removable and reusable asrequired.

Installation Considerations

After the Screw Anchor is spun onto and bottoms against the ScrewAnchor Setting Bolt, it should be tightened securely. This tighteningconforms the coils against the bolt threads for proper fit andfunction. If not properly tightened as described above, a thread mis-match may occur. It is a good practice to back-off the Setting Bolt aquarter to a half turn about eight to twelve hours after the concretehas been poured. This breaks the concrete bond and permits easierbolt removal.

Determining Screw Anchor Bolt Length

Screw Anchor Setting Bolt

To calculate proper Setting Bolt LengthSetting Bolt Length = A+B+Grip

A = Length of Screw AnchorB = Set Back of the Screw Anchor

from the face of the concrete.Grip = Thickness of the form and/or Setting Template

through which the Setting Bolt passes.

Standard Screw Anchor Bolt

To calculate final bolt length (Standard Screw Anchor Bolt)Final Bolt Length = (A+B+Grip) - ½d

A = Length of Screw AnchorB = Set back of the Screw Anchor from

the face of the concreteGrip = Thickness of the form or fixture to be anchored.½d = One half of the Setting Bolt’s diameter.

Limitations: The NCA Wilson Anchor Sleeve is not recommendedwhere high heat is used, such as inside an oven.

Caution: When using the NCA Wilson Anchor Sleeve outdoors orunder freezing conditions, the sleeve must be sealed around the boltto prevent moisture penetration or filled with Antifreeze.

Installation: The bottom of the sleeve is passed over the top of thebolt until the threaded portion engages the self-threading top of thesleeve. The sleeve is turned until the proper projection is obtained.The entire assembly is cast into the concrete, with the top of thesleeve at foundation level. When the anchor bolt is ready foradjustment, the top of the sleeve is cut off and discarded. The boltmay now be adjusted within the sleeve. Expansion or non-shrinkinggrout is cast into the sleeve around the bolt when equipment is set.Other applications are done in a similar fashion.

Required Screw Anchors

Determining total load

To determine the total load to be supported by each falsework bracket, compute the total mass (weight of concrete) plus the liveload (weight of form and other temporary loads) and divide by the number of brackets to be used.

Example:The dimension of a concrete beam to be poured over two columns and supported by 4 brackets is as follows:

750 mm wide x 1200 mm high x 18,500 mm long(30" wide x 48" high x 740" long)

Density of concrete assumed = 2,400 kg/m3 (150 lb/Ft3)Live load or mass per unit area assumed = 365 kg/m2 (75 lb/Ft2)

Mass of beam .75 m x 1.2 m x 18.5 m x 2400 = 39,900 kg (18,100 lbs)Mass of live load .75 m X 18.5 m X 365 = 5,065 kg (2,300 lbs)

_________________________________44,964 kg (20,400 lbs)

Force exerted by mass = 44,964 x .00981 = 441.10 kN (99,100 lbs)

Force per bracket: 441.10 = 110.28 kN (24,800 lbs)

Therefore use 4 hole bracket with four 32 mm (1¼") diameter Screw Anchors.

NCA RICH-COTETM

A premium liquid debonding agent developed especially for concrete.Through a chemical reaction, RICH-COTETM produces a smooth, white,flat concrete surface which is free of voids and will bond with paint,plaster, tiles and any other coating applied directly to the concrete.

RICH-COTETM reacts positively with the alkalis in the concrete forminga water resistant barrier with the concrete that prevents it frombinding to the forms.

RICH-COTETM waterproofs plywood forms preventing the alkalis in theconcrete from being absorbed and rotting the wood. It is compatiblewith any pre-oiling done at the mill or any other substance previouslyused for treating forms. It will not wick out or wash off. Continueduse makes forms completely waterproof and extends their lifeconsiderably.

RICH-COTETM can be sprayed at sub-freezing temperatures. It will notstain and will reduce finishing time by 50%. RICH-COTETM makes formstripping easier and faster. For the most effective and economicalmethod of application use the NCA Form Sprayer.

Drying Time:1 - 2 hours — leaving a completely workable, non-slip surface.

Coverage: 12-18 square metres per litre on most forms. 18 - 25 square metres per litre on plastic coated and steel forms.

NCA Expamet Hy-rib is easily formed on the jobsite, making itadaptable to varying bulkhead conditions. Sheets allow quick tying ofreinforcing. The thinness and flexibility of Hy-rib allows it to be usedin dense rebar sections. It accommodates heavy bending anddoweling of rebar more cheaply. This would be difficult to do withconventional plywood.

With some construction joints, plywood is almost impossible toremove. With Expamet Hy-rib, the sheets remain in the concrete with

no labour involved for removing the sheets.

General Guidelines and ConditionsSAFE WORKING LOADS: The Safe Working Loads published in this brochure can only be obtained whenNCA products and accessories are used together. Products must be installed correctly to obtain the fullstrength development as illustrated below.

Ensure that internal vibrationhas not caused Snap-Ty Wedgesto bounce around, loosen or falloff.

It is important to properlyposition the Snap-Ty head andthe wedge.

Walers spaced too far apart maycause crushing of the wales orbending of the wedge, causingthe form to bulge outward.Incorrect wall thicknesses willresult and cause the Ty SpreaderWashers or Cones to becomeembedded in the concrete.Embedded Ty Washers or Coneswill make it difficult to breakback the Tys.

The Ty Head must not bepositioned lower than themidpoint of the wedge. Theproper Ty Head position is at themidpoint of the wedge slot, orhigher.

Page 105: NCA Concrete Forming Systems

APPENDIX

103

Ty cones and metal washers areused to act as form spreadersonly.

The wedge should not beovertightened by any method.Attempting to draw-up warpedwales with the wedge shouldnot be attempted. Metalspreader washers will bend outof shape and plastic cones willbreak if over tightening isattempted, resulting in incorrectwall thickness.

To achieve proper formstructures, it is important that allform tys are installed and usedproperly.

Excessive loads will betransferred to adjacent tys andcan result in form failure if tysand/or their required hardwareare omitted.

Ensure that form tys are properlyaligned. Increased loads placedon form tys because ofmisalignment may cause formfailure to occur. Also, reducedload capacities can result fromform tys damaged because ofmisalignment during installation.

The maximum space betweendouble walers should be 13 mm(½") more than the nominaldiameter of a forming devicebeing used ie He-Bolts, Taper-Tys,She-Bolts and Lagstud Bolts.

Lag stud bolts and other lagthread products must have properlag penetration. A minimum ofone diameter of the bolting devicepast the coil is the properpenetration. As an example, alagstud bolt that is 25 mm (1") indiameter should extend aminimum of 25 mm (1") past thecoil. Form failure can result ifthreaded items are penetratedincorrectly. Excessive wear on thebolt’s first few threads are causedfrom improper penetration andthe entire bolt load is placed on asmaller portion of the coil welds.The coil welds can fail and causeform failure because of thisincreased load.

Wales may be crushed or washersmay bend if too much space isallowed between the walers. Toomuch space causes the form tomove outward and will result inincorrect wall thickness andspreader cones becoming trappedin the concrete. Incorrect wallthickness can also be caused fromwashers being deflected due tothe increased lateral formpressure.

Page 107: NCA Concrete Forming Systems

APPENDIX

105

Do not force tys into position.Forcing the tys may damage the tyand result in form failure.

Do not use incorrect length Tys anddo not mix incorrect form Tylengths with correct ones. Doing sowill cause a transfer of lateralpressure to adjacent tys and mayresult in form failure.

Do not use the form tys forclimbing.

Impact wrenches should not beused to tighten form tying devices.

Do not vibrate the concreteexcessively or the concrete at thebottom of the form will stay inliquid state longer than should beexpected. The liquid state willcause a higher than expectedlateral form pressure and couldcause a form failure.

The recommended rate ofplacement should not be exceeded.If the concrete at the bottom ofthe form is still in liquid state donot continue to place concrete.Form failure may result.

Working parts below the specifiedrequirements should not be usedwith forming accessories.

Use accessories and hardware ofproper length, diameter andcapacity. If it is necessary to use a greater safety factor, the safeworking load must be reducedaccordingly.

Use caution when welding anyforming system component.Material properties may beaffected by welding and result in lower product performance. Agood working knowledge ofmaterials, heat treating andwelding procedures is requiredbefore welding any formingaccessory. National ConcreteAccessories does not guarantee any product altered in any wayafter leaving the factory.

Stripping of Snap-Tys and guidelines for break back

NCA Snap-Ty break backs are manufactured to exacting standards thatensure that they perform to load requirements while providing aconsistent and reliable breaking point. However, many factors affectthe performance of the break backs.

• Snap-Tys must not be bent during installation as the break backcould be adversely affected.

• For best results, Tys are not to be removed until concrete hasgained sufficient strength to prevent the Ty upset from rotating —typically 2 to 3 days. Attempting to break the Ty in green concretemay result in the Ty rotation in the concrete and make it difficult tobreak the Ty.

• Only Space-Tys have a guaranteed break back.• Other Snap-Ty products are designed to provide a consistent break

back, but can be affected by the concrete, which could generatedifficulties in achieving a consistent break back.

• Products like the Steel Washer, No Washer and No Spreader Snap-Tys where the break back could be contained within the concreterequire extra attention. With increased bond length NCA cannotguarantee that the Ty will consistently provide the proper breakback. For these products, this is especially important where breakbacks of over ¾" (20 mm) are desired. A good quality releaseagent/grease (acceptable non-staining) applied between the breakback and the face of formwork (grease wire to be embedded, thatwill be removed — do not grease head area) may facilitate moreconsistent results. On site tests should be conducted to identify ifconsistent results can be achieved with the concrete mix and Ty.

• If the washer or cone is not free of the concrete, chip away theconcrete using a hammer, screwdriver or drill to free the embeddedcomponents. Failure to free up the embedded components couldresult in the break back closer to the surface of the concreteinstead of the desired break back location.

Use of the NCA Snap-Ty and Space-Ty wrenches will assist withconsistency, reduce risk of injury and speed up removal (see pages 22and 23).

If in doubt, contact NCA’s technical department for assistance.

Concrete inplastic state

Once bottomfoot is cured

Once second foot ofconcrete is cured

Lateral pressure decreases from bottom as concrete cures.

Concrete cures and gains strength faster with an increase in temperature.

As you increase the height of plastic concrete to the forms, the pressure will build at a rate of 150 PSF per foot of depth. This will be true as long as all concrete remains in a plastic state.

Example: Ten feet of fluid or plastic concrete bears on the bottom foot of forms with a pressure of 10 X 150 lbs/ft3 or 1500 PSF.

Example: At 21˚ C (70˚ F), concrete sets in approximately 1¼ hour. At 4.5˚C (40˚ F) concrete will set up in about 1¾ hour.

5) Wood design is based on CAN3-086-M84 Engineering Design in Wood(working stress design).

6) Formwork design based on CAN/CSA-S269.3-M92 concrete formwork —National Standard of Canada.

Wallform Pouring InformationForm Tys are spaced for maximumconcrete pressure of 1500 PSF at safeload values of Tys. Assumed pouring ratefor “Portland Cement” concrete only atvarious temperatures as indicated inabove charts.

Estimated time of set for charts:1.75 hours @ 40° to 50° F, 1.25 hours @

60° to 70° F, 1.5 hours @ 50° to 60° F,1 hour @ 70° to 80° F

Wallform and product design is based onthe following assumptions:

— Concrete is placed by bucket from topof form (not pumped)

— Concrete pressures are full liquid headunless a maximum concrete pressure isspecified above

— Concrete mix using type 10 or type 30cements maximum slump of 100mm(4") for controlled pours

— Compliance with “ConcreteFormwork” standard CAN/CSA-S269.3-M92

Loads based on mechanicalproperties only

Consult the National ConcreteAccessories Technical Departmentwhen concrete strengths are less than3.4 MPa (500 psi). Estimated practicalload values are shown for variousstrengths of concrete. Safety factors(ultimate load: working load) isdetermined at 2:1.

Use lighter anchor unit in concreteabove 4.8 MPA (700 psi) for same loadcapacity.

A good forming practice is to preloadre-anchorage units to safe workingload prior to pouring lift. Slippage willindicate inadequate concrete strength.This practice is especially critical inconcrete under 3.4 MPa (500 psi).

These are guide figures drawn fromcomprehensive tests and accumulateddata, and performance will varysomewhat under different conditions.For specific job conditions a check testis recommended under field conditionsafter a selection is made. It is notconsidered desirable to plan canteliveroperation below 2.7 MPa (400 psi).Type 50, cement jobs have run as lowas 450 psi @ 7 days. Below 400 psi,cycle increases for 400 psi minimumare indicated as good procedures.
