Elementary safety warnings

User target groups● This User Information booklet (Method Statement) is

aimed at everyone who will be working with the Doka product or system it describes. It contains informa-tion on the standard design for setting up this sys-tem, and on correct, compliant utilisation of the sys-tem.

● All persons working with the product described herein must be familiar with the contents of this man-ual and with all the safety instructions it contains.

● Persons who are incapable of reading and under-standing this booklet, or who can do so only with dif-ficulty, must be instructed and trained by the cus-tomer.

● The customer is to ensure that the information mate-rials provided by Doka (e.g. User Information book-lets, Instructions for Assembly and Use, Operating Instruction manuals, plans etc.) are available to all users, and that they have been made aware of them and have easy access to them at the usage location.

● In the relevant technical documentation and form-work utilisation plans, Doka shows the workplace safety precautions that are necessary in order to use the Doka products safely in the usage situations shown. In all cases, users are obliged to ensure compliance with national OH&S (occupational health and safety) rules throughout the entire project and to take appro-priate additional or alternative workplace safety pre-cautions where necessary.

Hazard assessment● The customer is responsible for drawing up, docu-

menting, implementing and continually updating a hazard assessment at every job-site. This document serves as the basis for the site-spe-cific hazard assessment, and for the instructions given to users on how to prepare and utilise the sys-tem. It does not substitute for these, however.

Remarks on this document● This User Information booklet can also be used as a

generic method statement or incorporated with a site-specific method statement.

● Many of the illustrations in this booklet show the situation during formwork assembly and are therefore not always complete from the safety point of view.

● Further safety instructions, especially warnings, will be found in the individual sections of this document!

Planning● Provide safe workplaces for those using the form-

work (e.g. for when it is being erected/dismantled, modified or repositioned etc). It must be possible to get to and from these workplaces via safe access routes!

● If you are considering any deviation from the details and instructions given in this booklet, or any application which goes beyond those described in the booklet, then revised static cal-culations must be produced for checking, as well as supplementary assembly instructions.

Rules applying during all phases of the assignment:● The customer must ensure that this product is

erected and dismantled, reset and generally used for its intended purpose under the direction and super-vision of suitably skilled persons with the authority to issue instructions. These persons' mental and physical capacity must not in any way be impaired by alcohol, medicines or drugs.

● Doka products are technical working appliances which are intended for industrial/commercial use only, always in accordance with the respective Doka User Information booklets or other technical docu-mentation authored by Doka.

● The stability of all components and units must be ensured during all phases of the construction work!

● The functional/technical instructions, safety warn-ings and loading data must all be strictly observed and complied with. Failure to do so can cause acci-dents and severe (even life-threatening) damage to health, as well as very great material damage.

● Fire-sources are not permitted anywhere near the formwork. Heating appliances are only allowed if properly and expertly used, and set up a safe dis-tance away from the formwork.

● The work must take account of the weather condi-tions (e.g. risk of slippage). In extreme weather, steps must be taken in good time to safeguard the equipment, and the immediate vicinity of the equip-ment, and to protect employees.

● All connections must be checked regularly to ensure that they still fit properly and are functioning cor-rectly. It is very important to check all screw-type connec-tions and wedge-clamped joins whenever the con-struction operations require (particularly after excep-tional events such as storms), and to tighten them if necessary.


5999732002 - 07/2009 NK


Assembly● The equipment/system must be inspected by the

customer before use, to ensure that it is in suitable condition. Steps must be taken to rule out the use of any components that are damaged, deformed, or weakened due to wear, corrosion or rot.

● Combining our formwork systems with those of other manufacturers could be dangerous, risking damage to both health and property. If you intend to combine different systems, please contact Doka for advice first.

● The assembly work must be carried out by suitably qualified employees of the client's.

● It is not permitted to modify Doka products; any such modifications constitute a safety risk.

Erecting the formwork● Doka products and systems must be set up in such

a way that all loads acting upon them are safely transferred!

Pouring● Do not exceed the permitted fresh-concrete pres-

sures. Excessively high pouring rates lead to form-work overload, cause greater deflection and risk causing breakage.

Striking the formwork● Do not strike the formwork until the concrete has

reached sufficient strength and the person in charge has given the order for the formwork to be struck!

● When striking the formwork, never use the crane to break concrete cohesion. Use suitable tools such as timber wedges, special pry-bars or system features such as Framax stripping corners.

● When striking the formwork, do not endanger the stability of any part of the structure, or of any scaf-folding, platforms or formwork that is still in place!

Transporting, stacking and storing● Observe all regulations applying to the handling of

formwork and scaffolding. In addition, the Doka slinging means must be used - this is a mandatory requirement.

● Remove any loose parts or fix them in place so that they cannot be dislodged or fall free!

● All components must be stored safely, following all the special Doka instructions given in the relevant sections of this User Information booklet!

Regulations; industrial safety● Always observe all industrial safety regulations and

other safety rules applying to the application and uti-lisation of our products in the country and/or region in which you are operating.

Instruction as required by EN 13374:● If a person or object falls against, or into, the side-

guard system and/or any of its accessories, the side-guard component affected may only continue in use after it has been inspected and passed by an expert.

Maintenance● Only original Doka components may be used as

spare parts.

Eurocodes at DokaIn Europe, a uniform series of Standards known as Eurocodes (EC) was developed for the construction field by the end of 2007. These are intended to provide a uniform basis, valid throughout Europe, for product specifications, tenders and mathematical verification.The EC are the world's most highly developed Stand-ards in the construction field.In the Doka Group, the EC are to be used as standard from the end of 2008. They will thus supersede the DIN norms as the "Doka standard" for product design.

The widely used "Permissible stress design" (compar-ing the actual stresses with the permissible stresses) has been superseded by a new safety concept in the EC.The EC contrast the actions (loads) with the resistance (capacity). The previous safety factor in the permissible stresses is now divided into several partial factors. The safety level remains the same!

Comparison of the safety concepts (example)

Ed Design value of effect of actions (E ... effect; d ... design) Internal forces from action Fd (VEd, NEd, MEd)

Rd Design value of the resistance (R ... resistance; d ... design) Design capacity of cross-section (VRd, NRd, MRd)

Fd Design value of an actionSteel: Rd =

Rk Timber: Rd = kmod ·Rk

Fd = γF · Fk γM γM

(F ... force)Fk Characteristic value of an action

"actual load", service load (k ... characteristic) e.g. dead weight, live load, concrete pressure, wind

Rk Characteristic value of the resistance e.g. moment resistance to yield stress

γF Partial factor for actions (in terms of load; F ... force) e.g. for dead weight, live load, concrete pres-sure, wind Values from EN 12812

γM Partial factor for a material property (in terms of material; M...material) e.g. for steel or timber Values from EN 12812

kmod Modification factor (only for timber – to take account of the moisture and the duration of load action) e.g. for Doka beam H20 Values as given in EN 1995-1-1 and EN 13377

The "permissible values" communicated in Doka documents (e.g.: Qpermissible = 70 kN) do not correspond to the design values (e.g.: VRd = 105 kN)!➤ Avoid any confusion between the two!➤ Our documents will continue to state the per-

missible values. Allowance has been made for the following par-tial factors: γF = 1.5 γM, timber = 1.3 γM, steel = 1.1 kmod = 0.9In this way, all the design values needed in an EC design calculation can be ascertained from the permissible values.

Instructions for assembly and useThe sequence shown here is based on a straight wall. However, you should always start to form from the cor-ner outwards.Ladders must be located so as to create viable "traffic routes" in the horizontal. (On a straight wall, for exam-ple, one ladder on the first element and another on the last).

Pre-assembly➤ Pre-assemble the elements face-down on an

assembly bench (see "Element assembly").

➤ Mount the platforms to the face-down element (see "Pouring-platforms with single brackets").

➤ Mount the ladder system to the face-down element (see "Ladder system").

➤ Mount panel struts to the face-down element (see "Plumbing accessories").

Erecting the formwork➤ Attach the crane suspension tackle to the lifting-

brackets (see "Lifting by crane").

➤ Pick up the element by crane.➤ Spray the ply with release agent (see "Cleaning and

care").

➤ Fly the element to its new location.

➤ Fix the panel struts firmly to the ground (see "Plumb-ing accessories").

➤ Mount the top guard-rail board.

The element is now stable and can be plumbed and aligned exactly, with no need for the crane.

➤ Detach the element from the crane.➤ Continue lining up elements in this way, and link

them together (see "Inter-element connections").

Preconditions for use:

Platforms and all accessories must only be mounted to the element when this is face-down on the ground.

It must be possible for all formwork set-up, pouring and stripping operations to be carried out from safe workplaces.

The professionals from the Doka "Ready-to-Use Service" plan and assemble site-ready and custom formworks exactly to your speci-fications.

Erecting the opposing formwork:Once the reinforcement has been placed, the form-work can be closed.➤ Spray the ply with release agent (see "Cleaning and

care").➤ Lift the opposing formwork by crane to its next loca-

tion.

➤ Working from the ground, insert the bottom rows of form-ties (see "Form-tie system").

➤ Detach the element from the crane.➤ Insert the remaining form-ties. These form-tie loca-

tions can be reached from the platforms.➤ Continue lining up elements in this way, and link

them together (see "Inter-element connections").

Pouring

➤ Pour the concrete.➤ Make only moderate use of vibrators, carefully co-

ordinating the times and locations of vibrator use.

WARNINGThere is not yet an opposing guard-rail on the formwork!Danger to life from fatal falls!➤ Use personal protective equipment to pro-

tect against falls.

Before disconnecting from the crane:➤ If there are no panel struts on the opposing

formwork, do not disconnect the element from the crane until a large enough number of form-ties have been installed to keep it safely in the upright.

Striking

➤ Remove any loose items from the formwork and plat-forms, or secure them firmly.

Begin work on striking the formwork on the oppos-ing formwork:➤ Undo the connectors to the adjacent elements.

➤ Take out the form-ties from the top rows of ties. These form-tie locations can be reached from the platforms.

➤ Attach the element (incl. platforms) to the crane.➤ Working from the ground, take out the bottom rows

of form-ties.

➤ Lift the element away and to its next location, or place it face-down for intermediate storage.

➤ Clean residual concrete off the form-ply (see "Clean-ing and care").

➤ Where the element has panel struts attached to it, first attach this element to the crane, and only then detach the floor anchorages of the panel struts.

☞ ➤ Observe the stipulated striking times.

WARNING➤ There must be at least as many form-ties left

in place as are needed to keep the element safely in the upright.

WARNINGThe formwork tends to adhere to the concrete. When stripping the formwork, do not try to break concrete cohesion using the crane!Risk of crane overload.➤ Use suitable tools such as timber wedges or

a special pry-bar to detach the formwork from the concrete.

Flexibility

SizeTop 50 elements can be assembled in widths of up to 6 m and in heights of up to 12 m.

Pressure of fresh concreteDepending on the concrete pressure required, the Doka beams and the walings are spaced closer together or further apart. This ensures optimum form-work design and the greatest economy of materials.For more information on structural design of Top 50 elements, see "Structural design".

SurfaceAny type of form-face can be used, as required:● Doka formwork sheets 3-SO● Dokaplex formwork sheets● Doka textured formwork sheets● Xlife sheets● Tongue-and-groove board formwork etc.The tie-hole pattern and the element size-grid are eas-ily adapted to suit architectural demands. The large-area elements and exact connections deliver perfect joint patterns.

ShapeCreating complex concrete shapes demands a high degree of formwork flexibility. On the large-area form-work Top50, this is achieved by the use of profiled tim-ber formers.

Inside corners

with Corner waling 20With the Corner waling 20, it is possible to make a gen-uine inside-corner element. The Doka beams give the element the necessary rigidity, and also ensure dimen-sional accuracy.The adjacent Top 50 elements are fastened with the normal connector components.

with Internal angle plate H20 Top50An economical way of making inside corners with a closure function. (For closures of up to 32 cm in 1 cm increments)By nailing a form-ply to the end face of standard ele-ments, these are turned into corner elements. The con-crete pressure on the end face is transferred by means of reinforcements (e.g. Fastening plate) on the edge beam.

with Shaft corner waling WS10 Top50The Shaft corner waling WS10 Top50 is a 90°-welded steel waling used for making sturdy corner elements. This special waling is custom-built on a project-specific basis.The Shaft corner waling is often used for shaft form-work (see "Shaft formwork").

A Where statically necessary - place a tie through the Corner wal-ing 20.

☞ When connecting the Corner waling 20 to adjacent elements, please remember:If the Adjustable waling extension (A) reaches a long way into the Corner waling 20, no Form-work element connector FF20 Z may be used on the 2nd leg. Because of the "pull-tight function hole-grid", it is not possible to mount the Formwork element connector FF20 Z one hole-grid further along.In this case, use an Anchoring plate FF20/50 (B) instead.

Acute & obtuse-angled cornersFor non-right-angled corners, too, the standard compo-nents of the Large-area formwork Top 50 will always provide an optimum solution.

Outside cornersIn a similar way to the right-angled corners, on outside corners the elements are also mainly connected using Universal angle tie brackets.

Inside corners

with Articulated connecting plate A Top50 ..... °● Can be used on walings of 0.75 m and longer● Makes it possible to set two steel walings at any

angle (in a range between 61° and 299°)● Can be used over and over again

If there are no planned moments that need to be trans-ferred by the connecting plate (i.e. if it is being used as an ordinary user-adjustable form connector), it is suffi-cient to tighten the threaded joint using ordinary tools such as the Reversible ratchet 3/4".In order to achieve the stability required when the form-work is being lifted, a force of approx. 400 N should be applied to the approx. 75 cm long lever arm of a "Reversible ratchet 3/4" (to give a tightening torque of approx. 300 Nm).When used in this way as an ordinary user-adjustable form connector, it is not necessary to insert a new alu-minium locking ring. The hexagonal bolt M30x90 and the nut of the connection must always be greased before being tightened.

with Half splice plateHalf splice plates are used for fabricating low-cost cor-ner plates, with any angle, directly on the site.To make a corner plate in this way, two Half splice plates are needed. After the formwork has been plumbed at the prescribed angle, these two plates must be welded firmly together.

Permitted load:The Articulated connecting plate A Top50 .....° is designed to transfer a permitted bending moment of 9 kNm. If tensile forces (e.g. ring tensile forces) are to be transferred at the same time, the moment load must be reduced accordingly.

with Swivel joint plateThe Swivel joint plate is an alternative to using two Half splice plates welded onto one another.● Angles of between 45° and 180° are possible.● Rough adjustment is carried out in 35.7 mm incre-

ments (= 1/3 of the hole-grid of the Multipurpose wal-ing).

● Fine adjustment is carried out using the integral adjusting thread, with a max. theoretical formwork deviation of ±2.5 mm.

● Use suitable sealing tapes on any gaps which occur at joints.

Stop-end formwork

The Large-area formwork Top 50 is a complete form-work system. As such, it also offers practical solutions for e.g. the stop-end formwork.

Walls up to approx. 20 cm thickPlanks are simply nailed onto the Top50 element and a strip of formwork sheeting is inserted.

Walls thicker than approx. 20 cmThe Anchoring plate FF 20/50 ensures that the loads are safely transferred into the waling system of the Top50 elements.

The tie rods are screwed into the Anchoring plate, and the correct spacing of the stop-end element is adjusted using the Super plate 15.0.

Vertical stacking of elementsThe vertical-stacking methods shown here are only suitable for:● lifting● setting down and● crane-handlingthe formwork.

with Stacking plate H20The Stacking plate H20 serves as a bolt-on longitudinal connector for Doka beams, and is used for vertical stacking of formwork elements. The plate is bolted onto the beams through the pre-drilled holes at either end of the beam.

a ... min. 40 cm

The number of Stacking plates H20 needed will depend on the overall height of the gang-form:● Up to an overall height of 6.0m: A Stacking plate

H20 must be fastened to every other beam.● Up to an overall height of 8.0m: A Stacking plate

H20 must be fastened to every beam.In addition, it is advisable to place extra multipurpose walings across the horizontal joins, in order to achieve greater stability.

● Over 8.0 m, up to a max. overall height of 14.0 m: A Stacking plate H20 must be fastened to every beam.In addition, it is absolutely essential to place extra multipurpose walings across the horizontal joins, in order to achieve sufficient stability.

Included in scope of supply:● 4 hexagonal bolts M20x70 (width-across 30 mm)● 4 hexagon nuts M20● 4 spring washers A20

Note:Make sure that the bolted connections are tightened firmly!

with board-platesAn in-situ solution that often works well in practice. The existing holes at the end of the beam can be used for making the bolted connections.

Items needed for each beam join:

*) It is also possible to use strips of 3-SO 21 or 27 mm formwork sheet instead of the planks.

☞ Important note:The vertical stacking joint must not be exposed to loads from concrete pressure or concrete weight. This means:● that the cantilever arms at the beam-joints

must be as short and symmetrical as possi-ble,

● or that users must take all statically required measures (e.g. extra waling level).

Plumbing accessories

Panel struts, Eurex 60 550 and Adjustable plumb-ing struts secure the elements against wind loads, and make it easier to plumb and align the formwork.

Permitted spacings [m] of the plumbing accesso-ries:

The values apply where the wind pressure we = 0.65 kN/m2. This results in an impact pressure qp of 0.5 kN/m2 (120 km/h) where cp, net = 1.3. In cases where higher wind pressure is encountered, the number of props must be determined by statical calculation.

Note:Every gang-form must be supported by at least 2 panel struts.

Example: Where the formwork height is 7.00 m, the fol-lowing are needed for every 8.00 m wide gang-form:● 2 Panel struts 340● 2 Eurex 60 550 / Adjustable plumbing struts

Pouring platforms with single brackets

Doka brackets can be used to make pouring platforms that can easily be assembled by hand.They can be attached to any point on the Doka beam. This also makes it possible to erect intermediate plat-forms.

Universal brackets

Possible ways of fixing Universal brackets in the Doka beam H20

Preconditions for use:

Observe all applicable safety regulations.

Only fix the pouring platform onto formwork construc-tions that are sufficiently stable to transfer the expected loads.

Ensure that the formwork gang has sufficient stiff-ness.

Shore the formwork in a windproof manner when erecting it and when it is temporarily placed in the standing position.

☞ The brackets must be secured against acciden-tal lift-out
