Joists are the primary structural component of the QuikDeck® Suspended Access System. Joists connect with nodes to form a grid for deck supports and decking.

Cage nuts are positioned along the joist top-member in eight locations and are used to fasten deck retainers and toeboards. Each joist has three “hard point” locations that provide structural connection for auxiliary suspender brackets. Removal of cage nuts is required to install auxiliary suspender bracket.

Anti-rotation pin location limits joist rotation during platform installation.

Joist-to-node connection contains a tubular end connection that strengthens the joist, guides node pins, and provides location for handling and tie-off during assembly.

1.2 Assembling the Starter PlatformTo ensure safe and efficient erection of the QuikDeck® Suspended Access System, starter platform size and hoisting configuration should be developed through careful planning and preparation.

To prevent excessive drifting of the platform during hoisting, starter platforms should be assembled directly under their final location.

The area under and around the starter platform must be secured to prevent danger of falling objects. Falling objects may result in property damage, personal injury or death.

! WARNING CONTACT BRANDSAFWAY FOR REVIEW AND APPROVAL OF STARTER PLATFORM CONFIGURATIONS NOT SHOWN IN THIS GUIDE.

HOISTING OF EXCESSIVELY LARGE STARTER PLATFORMS OR STARTER PLATFORMS IMPROPERLY RIGGED MAY CAUSE COMPONENT FAILURE, RESULTING IN PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

Assembling the Starter Platform

1.1 Material Handling

! WARNING THE AREA UNDER AND AROUND THE STARTER PLATFORM MUST BE SECURED TO PREVENT DANGER OF FALLING OBJECTS. FALLING OBJECTS MAY RESULT IN PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

! WARNING OVERLOADING THE QUIKDECK® SUSPENDED ACCESS SYSTEM CAN CAUSE COMPONENT FAILURE, RESULTING IN PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

Material handling can require significant resources when staging and assembling large platforms. For safety and efficiency, plan ahead to secure adequate unloading, staging areas and appropriate material handling equipment. If ground access and hoisting and/or material handling equipment are available, it may be possible to unload materials directly onto the QuikDeck® platform.

However, always be aware of the loads being applied to the platform. It is likely that the largest loads ever applied to the platform will be from the staging of QuikDeck® components.

1.12 Angled SuspendersWhen using suspenders at an angle, it is important to insert the chain in the proper node chain slot.

The node is equipped with 4 chain slots - one chain slot for each of four quadrants. Chain must be inserted into a chain slot such that the load on the chain seats the chain further into the slot, rather than pulling the chain out of the slot and applying side load against the chain retainer. The chain retainer is designed to prevent the chain from being withdrawn from the node–thechainretainerisnot designed to take side load from an angled suspender.

! WARNING FAILURE TO INSERT THE CHAIN IN THE PROPER CHAIN SLOT COULD CAUSE FAILURE OF A SUSPENDER, RESULTING IN PROPERTY DAMAGE, PERSONAL INJURY OR DEATH. MAXIMUM ALLOWABLE CHAIN TENSION/ANGLES DEPEND ON PLATFORM RATING AND SUSPENSION LOCATION.

1.13 Leveling the Platform1. Repeat Section 1.11 at 3 other hoist locations.2. For remaining nodes, use QDTH or other appropriate hoist

to level and support the node locations while installing suspension chains.


Figure 50 – Leveling the Platform


Figure 52 – Completed Starter Platform, 75 psf (366 kg/m²)

Guidelines for use of the QuikDeck® lever hoist as a suspender adjuster:

■■ The suspender adjuster shall only be used by properly trained personnel.

■■ Never use the suspender adjuster as a permanent suspension component.

■■ Never use the suspender adjuster to hoist personnel or materials.

■■ Never use the suspender adjuster in configurations where failure of the suspender adjuster will result in failure of the platform or its components.

Prior to using the QuikDeck® Suspender Adjuster:■■ Ensure that removal of selected suspender

will not result in failure of the platform or its components.

■■ Always remove live and dead loads surrounding the suspender to be adjusted.

■■ Never overload the suspender adjuster. The suspender to be adjusted should NEVER support loadsofmorethan3,000lbs.

! DANGER LOAD RATINGS OF THE QUIKDECK® SUSPENDED ACCESS SYSTEM MAY BE REDUCED BY OVERLOADING, DAMAGE, DECAY, CORROSION, MISUSE, MODIFICATION OR IMPROPER MAINTENANCE.

Daily Inspection1. Inspect Platform For Excessive Deflection

Excessive deflection is a clear sign of platform overloading. If excessive deflection is observed, immediately evacuate the platform and secure area under platform. Remove load from platform and inspect platform, suspension components and supporting structural members for damage. Replace with BrandSafway-supplied components as required.

2. Inspect Wire Rope Clips Using torque wrench, and following manufacturer's instructions, inspect all wire rope clips used for suspension and wire rope guardrails for proper torque specifications. Re-torque as required.

3. Inspect Suspension Connections Check all platform and suspension assembly connections to ensure that they are in proper position and are in good working condition. Start inspection with beam clamp connections to structural members and chain leading from beam clamps to nodes. Ensure chain retainers are installed and are properly retained by plastic ties.

4. Inspect Wire Rope Check wire rope for signs of damage or exposure to heat or flame. Wire rope should be kept clean from build-up of debris and foreign materials. Replace wire rope as required.

5. Inspect Suspension Chain Check chain for twists or bends, nicks or gouges, stretch, signs of wear, and exposure to heat or flame. Replace chain as required.

6. Inspect For Missing Fasteners and Lanyards Check all connections for missing pins, fasteners and lanyards. Replace pins, fasteners and lanyards as required.

7. Inspect All Nuts and Bolts for Proper Torque Specifications Inspect all threaded fasteners for proper torque specifications. Re-torque fasteners as required.

8. Inspecting Decking Inspect decking for damage and decay. Replace decking as required. Always inspect decking panels prior to installation and after removal. Damaged decking panels can fail under load, resulting in property damage, injury or death. Damaged decking panels should never be used for decking on QuikDeck®. Deck panels suspected of damage should

be immediately removed from service. Proper inspection, storage, handling and use are necessary to ensure structural integrity and safe application of decking panels. Use of damaged decking panels may result in property damage, injury or death.

9. Damaged Decking Panels Some common types of damage to decking panels are:■■ Decay.Decay(orrotting)cansignificantlyreduce

load carrying capacity of decking panels. Indications of decking panel decay include changes in hardness, stiffness, color, texture and fiber brashness (low resistance to shock and failure across the grain without splintering).Deckingpanelswithsignsofdecayshould be immediately removed from service.

■■ Face Breaks. A break on the surface of a decking panel is the result of overloading. A face break looks like an irregularcrackacrossthetensionface(bottom)ofthedecking panel, or a small, straight wrinkle across the compressionface(top).Facebreaksresultinsignificantloss of load carrying capacity. Decking panels showing face breaks should be immediately removed from service.

■■ Accumulated Layers of Paint, Concrete, etc. Paint, concrete or other materials can accumulate on decking panels and prevent proper inspection. Decking panels that have accumulated layers of paint, concrete, etc. should be immediately removed from service, and all layers of accumulated materials or debris from decking panels should be removed to allow for proper inspection. Discard and replace decking panels if damage or decay is evident after removal of layers of materials or debris or if layers of materials or debris cannot be removed without causing damage to decking panel.

■■ Saw Cuts, Drilled Holes, and Notches. A saw cut, partially or fully through the decking panel, will significantly reduce the load capacity of a decking panel. Notches or drilled holes can have similar effects. Decking panels with saw cuts, drilled holes, or notches in them should be removed from service.

■■ Dents. Dents are caused by impact from falling objects or a dropped decking panel striking an object. Decking Panels with dents deeper than ¹⁄₁₆"(1.6mm)should be immediately removed from service.

Inspection and Maintenance


56

■■ Gouges and Depressions. Gouges or depressions (where pieces of wood have been torn from the faceofthedeckingpanel)maybetheresultofdamage from forklift handling, decay or chemical attack. Decking panels with gouges or depressions should be immediately removed from service.

■■ Splitting or Cracking. Splits or cracks are separations that extend through the decking panel from one face to another. Decking panels with end splits should be removed from service.

■■ Delamination. Delamination is a split that separates wood layers on the edge of a decking panel. Delamination can be caused by overloading, mechanical damage, decay or chemical attack. Delaminating layers that migrate diagonally across adjacent veneers may have been caused by overloading. Delaminating layers caused by overloading are likely to be accompanied by face breaks. Decking panels with delaminating layers should be removed from service.

■■ Discoloration. Discoloration might indicate exposure to decay, high temperatures or chemical attack. Decking panels that are entirely or partially discolored should be removed from service until the cause of the discoloration has been determined to be harmless.

■■ Other. Soft or crumbly wood might indicate chemical attack or decay. Odd odor might also indicate chemical attack. Decking panels that have soft or crumbly areas on them should be removed from service.

10. Preventing Damage to Decking Panels ■■ Impact Loads. Decking panels can be damaged if

objects are dropped or thrown onto the platform. Impose loads on suspended scaffolds gently and without impact. Decking panels that have been damaged by objects dropped or thrown onto the platform should be removed from service.

■■ Improper Handling. Decking panels can be damaged if dropped or thrown from the platform. Remove and store decking panels in an orderly manner. Corner protection should be used when moving bundles. Do not dump decking panels from trucks. Do not push bundles of decking panels with the ends of forklift forks. Decking panels that have been damaged by improper handling should be immediately removed from service.

■■ Decay. Decay of decking panels can significantly reduce load carrying capacity. To prevent wood decay, and subsequent loss of load carrying capacity, keep decking panels dry, and allow wet decking panels to dry quickly by providing adequate air circulation. Referto"ProperStorageofDeckingPanels."

■■ Improper Storage. Decking panels that are improperly stored are subject to biological and chemical attack and mechanical damage. Decking panels that have been damaged through improper storage should be carefully evaluated before use. Referto"ProperStorageofDeckingPanels."

■■ Overloading. If decking panels deflect significantly, or make cracking noises as load is being applied, they are being overloaded. Do not store heavy materials on decking panels. Decking panels that have been overloaded should be immediately removed from service.Referto"InspectionofDeckingPanels."

■■ Misuse. Decking panels should never be used for loading ramps, walkways, etc. or anything other than use as decking panels for QuikDeck®. Improper use of decking panels may cause damage to decking panels. Decking panels that have been misused should be immediately removed from service.

■■ Improper Reinforcement of Decking Panels. Consult "CustomizedApplications"(pgs.73–78)whendeckingpanels must be cut to fit around an obstruction to provide additional support in the area as detailed.

■■ Jumping. Never jump or bounce on decking panels.■■ Chemicals. Wood is susceptible to chemical attack. ObtainMaterialSafetyDataSheets(MSDS)foranychemicals being used on a job that are likely to come in contact with decking panels, and determine if there is risk of degradation of decking panels. Decking panels contaminated with hazardous chemicals should be immediately removed from service.

■■ Heat. Decking panels should not be exposed totemperaturesthatexceed150°F(65°C)asprolonged exposures to extreme heat can result in permanent loss of strength. Decking panels that have been subjected to high temperatures should be immediately removed from service.

11. Proper Storage of Decking Panels Proper storage and handling of wood decking panels will prevent unnecessary damage, decay and reduction of service life. To prevent decay, and to ensure structural integrity and long service life of decking panels, store decking panels in a manner that minimizes moisture and ensures proper air circulation. Do not store decking panels in contact with the ground and always separate with stickers to provide air circulation between panels.

12. Labeling and Storing Decking Panels Properly sticker and store neat bundles of decking panels on a level surface and protected from weather. To prevent water from coming in contact with stored decking panels, place bundles under a roof, cover with material, etc.

Provide adequate air circulation and drainage to ensure water, moisture and condensation can escape. Bundles of decking panels should be stacked with stickers spaced nomorethan6'(1.8m)on-center.Stickersshouldlineupvertically to provide access for forklift forks. Banding should be in-line with stickers. Banding that is misaligned with stickers or banding that is overly tensioned can result in bowed or damaged decking panels.



57

Weekly Inspection1. Inspect platform and components for damage or excessive

deflection. Damage or excessive deflection is a clear sign of platform overloading. Inspect all nodes, joists and beam clamp tubes for deformation of holes, bending or excessive deflection. If excessive deflection is observed, immediately evacuate the platform and secure area under platform. Remove load from platform and inspect platform, suspension components and supporting structural members for damage. Replace with BrandSafway-supplied components as required.

2. Inspect components for corrosion and decay. Check all structural components, pins and fasteners for evidence of corrosion and nodes, joists and beam clamp tubes for deformation of holes, bending or excessive deflection. Again, if excessive deflection is observed, immediately evacuate the platform and secure area under platform. Remove load from platform and inspect platform, suspension components and supporting structural members for damage. Replace with BrandSafway-supplied components as required.

3. Inspect components for damage to finish. Check for chipped or damaged galvanizing, paint or other surface coatings. Repair finish with zinc rich paint as soon as possible to prevent further corrosion. Note: this repair should only be performed by a person qualified to refurbish equipment.

Using Cut-to-Fit Joists

Cut-to-fit joists should only be used in applications where standard length joists will not fit and bending loads will not be applied. Contact BrandSafway Engineering Department for more information regarding use of cut-to-fit joists.

Cut-to-fit joists have limited bending strength and are not to be used to create spans longer than one cut-to-fit joist, or in cantilevered applications.

Guidelines for Application of Cut-to-Fit Joists■■ Nodes at either end of cut-to-fit joists

must have suspenders installed.■■ Cut-to-fit joists should never be cantilevered.

1. Determining the Span Length To prevent rotation of nodes, insert node pins at all anti-rotation locations where standard joists connect to nodes. Measure the center-to-center distance between the node holes that the cut-to-fit joist will span (Fig.108).Thisisthespanlengthandisacriticaldimension. Check the distance before proceeding. Note:Spanlengthmustnotexceed103"(2.6m).

2. Cutting the Support Tube to Length Subtract9¾"(0.25m)fromthespanlength.Measure out this distance from the pre-drilled end of the cut-to-fit tube, and mark on the undrilled end (Fig.109).Cuttubetolength(±0.013",±0.33mm).

Unless located at corner of platform, do not install platform suspension at nodes secured by fewer than 3 joists.

When using short joists, nodes should be supported by 3 joists unless located at corner of platform. If unable to use a third joist to secure the node, install deck retainers tostabilizenode(Fig.107).

Secure deck retainers to short joist in the usual manner utilizing ½-13deckretainerbolts.Install20deckscrewsthrough outer holes in deck retainer into plywood decking panel.

! DANGER UNLESS LOCATED AT CORNER OF PLATFORM, A NODE SUPPORTED BY ONLY TWO JOISTS MAY NOT HAVE PROPER STABILITY, RESULTING IN IMPROPER SUPPORT AND FAILURE OF PLYWOOD DECKING PANEL (FIGS. 105, 107).

FAILURE OF PLYWOOD DECKING PANEL MAY RESULT IN PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

3. Installing Joist Ends Using the standard QuikDeck® node pin and hitchpin clip, install two joist ends at the same node locations used to measure the span length (Fig.110).

4. Test Fitting and Marking Support Tube Using the pre-drilled hole locations in the support tube, temporarily attach to one of the installed joistends(Step3)using½-13x4½"hexboltsandlock nuts. Slide the other end of the support tube down into the pocket on the opposite joist end. Mark the four holelocations(twooneachside)onthesupporttube(Fig.111).Removethesupporttube.

Auxiliary Suspender Mounting Brackets


! DANGER WHEN USING AUXILIARY SUSPENDER BRACKETS SECURED TO JOISTS ON THE PERIMETER OF A PLATFORM, SUSPENSION LOADS MUST BE DIRECTED TOWARD THE INTERIOR OF THE PLATFORM.

DIRECTING SUSPENSION LOADS TOWARD THE OUTSIDE OF THE PLATFORM MAY RESULT IN JOIST FAILURE. JOIST FAILURE CAN RESULT IN PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

Suspension chain attached to auxiliary suspender mounting brackets must be in-line with perimeter joist or in toward the plywood decking.

Auxiliary suspender bracket loads can apply side loads to joists. Joists are normally braced against side loads by plywood decking panels.

However, joists located at perimeter of platform have plywood decking panels located only on interior side of joist.

Fitting Obstacles and Platform InterruptionsUsing optional components, the QuikDeck® Suspended Access System can be configured for a variety of applications. The following examples address building around obstructions and penetrations such as:

■■ Piping and conduits■■ Bridge piers■■ Bridge bearings

Components have been specifically designed to build around obstacles and penetrations. These include:

■■ Optional joists■■ Deck supports without pins■■ Deck reinforcement kits

Example 2

The obstacle falls completely within a single 8' x 8' (2.4 m x 2.4 m) grid, interfering with installation of a standard deck support.

1. Install two deck supports without pins on opposing sides of the obstacle. These deck supports may be installed in either direction, depending on the size and location of the obstacle.

2. Installa2"x6"(51mmx152mm)wooddeckreinforcement(withhangers)onthesidesoftheobstacle perpendicular to the deck supports.

3. Secure each end of deck reinforcement to a hanger withfour#10x1stainlesssteelwoodscrews. Hangers can be supported by a joist or a deck support.

Load PlacardsPlatform load signage is required on all suspended scaffolds.

For your convenience, load placards for the QuikDeck® Suspended Access System's three standard ratings are provided in this section. Copy and laminate the placard that correlates with the specific rating for your job.

Standard ratings are: 20 psf (97 kg/m²) 25 psf (122 kg/m²) 50 psf (244 kg/m²) 75 psf (366 kg/m²)

Contact BrandSafway for replacement load placards or if your configuration deviates from these standard load ratings.

Load placards should be displayed at all platform entry locations and elsewhere on the platform, in sufficient quantity determined by the contractor, so personnel can quickly determine platform load capacity.

For the highest visibility, load placards contain the same information on each side. It is recommended to keep these signs double-sided when copying. They can also be copied and placed back-to-back if printed single-sided.
