Elementary safety warnings

User target groups

● This User Information booklet (Method State-ment) is aimed at everyone who will be working with the Doka product or system it describes. It contains information on how to set up this sys-tem, and on correct, compliant utilisation of the system.

● All persons working with the product described herein must be familiar with the contents of this manual and with all the safety instructions it con-tains.

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

● The customer is to ensure that the information materials provided by Doka (e.g. User Informa-tion booklets, 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.

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 formwork (e.g. for when it is being erected/dis-mantled, 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 supervision of suitably skilled persons with the authority to issue instructions.

● Doka products are ONLY to be used in accord-ance with the Doka User Information booklets or other technical documentation provided by Doka.

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

● The functional/technical instructions, safety warnings and loading data must all be strictly observed and complied with. Failure to do so can cause accidents and severe (even life-threaten-ing) 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 distance away from the formwork.

● The work must take account of the weather con-ditions (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 equipment, and to protect employees.

● All connections must be checked regularly to ensure that they still fit properly and are function-ing correctly.It is very important to check all screw-type con-nections and wedge-clamped joins whenever the construction operations require (particularly after exceptional events such as storms), and to tighten them if necessary.

Assembly

● The equipment/system must be inspected by the customer before use, to ensure that it is in suita-ble 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 con-tact Doka for advice first.

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


5999787002 - 07/2008 Ü The Formwork Experts

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 formwork 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 sys-tem features such as Framax stripping corners.

● When striking the formwork, do not endanger the stability of any part of the structure, or of any scaffolding, 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 rele-vant sections of this User Information booklet!

Regulations; industrial safety

● Always observe all industrial safety regulations and other safety rules applying to the application and utilisation 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

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

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 pro-vide a uniform basis, valid throughout Europe, for product specifications, tenders and mathematical verification.The EC are the world's most highly developed Standards in the construction field.In the Doka Group, the EC are to be used as stand-ard 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" (com-paring the actual stresses with the permissible stresses) has been superseded by a new safety con-cept in the EC.The EC contrast the actions (loads) with the resist-ance (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 pres-sure, wind

Rk Characteristic value of the resistancee.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, windValues from EN 12812

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

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

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

Product description

Dokaflex 1-2-4 -

the versatile hand-set system for

floor-slabs

Dokaflex 1-2-4 can easily be adapted to fit any lay-out, simply by telescoping the Doka H20 top beams. The materials planning work is done by slide-rule, which appreciably reduces the costs of planning and operations scheduling.● no structural-design work is needed, as 1-2-4

shows you the maximum spacings for all slabs up to 30 cm thick

● you can tell at a glance whether the formwork has been set up correctly

Further advantages:● infill zones are managed within the system, mak-

ing it easy to accommodate walls and columns● for shoring heights of up to 5.50 m● any type of form-facing can be used● no need to measure up

Dokaflex 1-2-4 is ideal for enclosed spaces where the formwork superstructure can rest up against walls on all sides.Horizontal forces at exposed slab-edges, drop beams or steps in ceiling slabs must be restrained by strutting or back-stays.

Notes



System logic for all floor-slabs up to 30 cm thickThe straightforward logic underlying the Dokaflex 1-2-4 system means that there is no need for plan-ning and operations scheduling work. The quanti-ties are simply computed using the materials slide-rule

Spacing and positions of the compo-nent partsNo matter whether the beams are resting on, between or next to the marks, the maximum spac-ing is always plain to see.You can tell at a glance whether the formwork has been erected correctly, and without having to measure up.

x ... 0.5 m

Primary and secondary beamsThe 3.90m long Doka beam H20 top is used as a pri-mary beam, and the 2.65m long H20 top beam as a secondary beam.

Format of the formwork sheetsThe Dokadur panels, in formats of 200x50cm and 250x50cm (21 or 27mm), have just the right dimen-sions to fit exactly into the increment-grid of the Dokaflex system.

Instructions for assembly and use

Erecting the formwork

Putting up the floor props

➤ Place primary and secondary beams along the edges.The marks on the beams show you the maximum spacings:- every 4 marks for primary beams- every 6 marks for props with removable folding tripods

➤ Roughly adjust the height of the floor prop, using the fastening clamp.

The pegging holes are all numbered, which makes it easier to adjust the props to the same height.

➤ Insert a Lowering head H20 into the floor prop. Leave the correct amount of lowering play (a)!

➤ Put up each removable folding tripod.

➤ Put the floor prop into the tripod and fix it in place with the clamping lever.Before stepping onto the formwork, check again to make sure that the props have been correctly fixed in the tripods.

Setting up tripods in corners or up against walls

If it is not possible to completely unfold the legs of the tripod – e.g. at the edges of a structure or at floor breakthroughs etc. – we recommend fas-tening this tripod to an adjacent floor prop instead, where there is room for the legs to be completely unfolded.

☞ Important note:

As well as the instructions given here, the section headed "Reshoring props, concrete technology and striking" MUST be followed.

Caution!

➤ If the floor props are transported with the lowering heads still attached, you must secure these with a Spring-locked con-necting pin 16 mm to prevent them drop-ping out. This is particularly important when they are transported in the horizon-tal.

Clearance a between wedge and head-plate: 6 cm

9720-006

a

9720-006

☞ ➤ Do not oil or grease wedge-clamped joins.

The lowering heads that will be under the primary beams next to the walls must be turned inwards so that they can be knocked undone when the time comes to take down the formwork.

9720-240-019720-241-01

9720-204-01

9720-335-01



Inserting the primary beams

➤ Using beam-forks, place the primary beams into the lowering heads.

The lowering heads can hold both single beams (on edge-of-room props) and double beams (at overlaps).

➤ Adjust the primary beams to the correct floor-slab height.

Placing the secondary beams on the primary beams

➤ Use the beam forks to place the secondary beams on the primary beams, with an overlap.

Maximum spacing of secondary beams: 1 mark

Warning!

➤ It is not permitted to set down any loads on the floor-slab formwork (e.g. beams, panels, reinforcements) until the interme-diate props have been set up!

Planks can be attached to the floor props as diagonal braces, using the Bracing clamp B. (This is only to help stand the props upright and is not suitable for restraining horizontal loads).

9720

-003

9720-205-01

Putting up the intermediate props

➤ Place the Supporting head H20 DF on the inside tube of the floor prop and secure it with the inte-gral spring-steel stirrup.

➤ Put up the intermediate props.

Maximum prop spacing: 2 marks apart

Laying the Dokadur panels

➤ Mount guard rails around all exposed edges.

There are 4 possible ways of ensuring safety when laying the Dokadur panels:● A mobile fall barrier makes it possible to lay the

Dokadur panels safely when working from above.

● The Wheel-around scaffold DF makes it possible to place the Dokadur panels from below.

● It is also possible to use a lightweight platform – as described in Section 8D - 7 of the "Construc-tion Health and Safety Manual" – to provide pro-tection along edges where panels need to be laid in the course of forming operations.

● If no fall barrier is used, all persons placing the panels from above must be secured with safety harnesses.

➤ Lay the Dokadur panels at right angles to the sec-ondary beams.

➤ Spray the Dokadur panels with parting agent.

PouringTo protect the surface of the form-facing, we rec-ommend using a vibrator with a protective rubber cap.

Striking

Removing the intermediate props

➤ Remove the intermediate props and put them in the stacking pallet.

After the intermediate props have been removed, there remain only props spaced 2.0 m apart in the direction of the secondary beams and 3.0 m apart in the direction of the primary beams. This leaves enough space to manoeuvre wheel-around scaf-folds and stacking pallets without difficulty.

Where necessary (e.g. edge zones), secure the form-ply with nails.

Recommended nail lengths● sheet thickness 21 mm - approx. 50 mm● sheet thickness 27 mm - approx. 60 mm

☞ Windproofing

● For increased stability, in larger rooms, the full erection sequence of "primary beams + secondary beams + formwork sheets" should be carried out progres-sively for successive sub-areas of the room.When doing this, provide suitable bracing to walls or columns.

● If there is any risk of the formwork being blown over, all free-standing, non-enclosed areas of slab formwork must be secured during work-breaks and when work finishes for the day.

9720-330-01

☞ Observe all stipulated stripping times!

The Wheel-around scaffold DF is ideal for striking the formwork from floor-slabs above rooms of medium height.

● collapsible wheelaround platform made of light alloy

● variable working heights of up to 3.80 m (max. platform height: 1.75 m)

● platform width: 0.80 m

For greater heights than this, the Doka mobile scaffold tower Z is ideal.

9720-006

9768-219-01



Lowering the floor-slab formwork

➤ Lower the floor-slab formwork by striking the wedge on the lowering head with a hammer.

Removing parts that are no longer needed

➤ Turn the secondary beams over onto their sides, pull them out and put them in the stacking pallet. Leave the beams under the panel-joints in place.

➤ Take out the Dokadur panels and put them in the stacking pallet.

➤ Remove the remaining secondary beams and the primary beams, and put them in the stacking pal-let.

Removing the floor props

1) Hold the inner tube with one hand.2) Open the fastening clamp to unfix the inner tube.

Guide this by hand while lowering it into the outer tube.

➤ Put the removable folding tripods and props in the stacking pallet.

Repropping➤ Before pouring the next floor-slab (i.e. above the

one that has just been stripped), put up reshoring props.

9720-007

-008

9720-009

When lifting the equipment to the next sto-rey, it is better to transport the floor props and the lowering heads separately (the floor props on their own can be stored much more space-savingly in the stacking pallet).

System components of Dokaflex 1-2-4– also for slab thicknesses of over 30 cm

Only one system in use on the siteUp to a slab thickness of 30 cm, no structural design work is needed. However, it is also possible to com-pute the exact quantities – of the same system com-ponents – that will be needed for any given thick-ness of slab, with reference to the table.In this way, only as much formwork equipment is used as is really needed, as dictated by the slab load.The following tables assume a live load of 20 per-cent of the dead load of the fresh concrete, but not less than 1.5 kN/m² (150 kg/m²). Mid-span deflection has been limited to l/500.

On the site, the easy-to-use slide-rule is ideal for determining the permissible spacing of primary beams and props.

Floor formwork around edgesIt can be advantageous to combine Dokaflex 1-2-4 with Dokamatic tables, particularly in edge-zones.The formwork for drop-beams and stop-ends, and the safety railings, can all be integrated in the edge tables.

Without edge drop-beam

Using Dokaflex 1-2-4 on edge zones

If no separate edge tables are available, the follow-ing points must be remembered when using Dokaflex 1-2-4:● In order to be able to transfer the horizontal

forces, the superstructure components must be firmly attached to one another.

● The back-stay can be fastened to either the sec-ondary or primary beam.

Beam forming supportThe Beam forming support 20 is the professional way of forming drop beams and slab stop-ends. In conjunction with the "Extension 60 cm for beam support", exact height adjustment to within 1 cm is possible.This does away with time-consuming jobsite squared-timber constructions. The Beam forming support automatically clamps the formwork tight, resulting in clean concrete surfaces and grout-tight edges.

How to use the Beam forming sup-

port 20➤ Place the Beam-forming support onto the H 20

secondary beam and push it up against the side-wall formwork.

The large bearing surface of the Beam-forming support gives the sidewall formwork a high degree of (90°) angle accuracy.

➤ Clamp the Beam forming support firmly into position

The diagonal bracing of the Beam-forming sup-port ensures that the joint between the form-ply sheets is automatically pressed together tightly when the Beam forming support is clamped.

This results in a clean concrete surface.

Formwork beams horizontal

(up to a height of 60 cm)

Note:

As a basic rule, it is forbidden to use formwork beams "horizontally" (i.e. with the load-direction perpendicular to the web). However, the specific applications shown here, using the Beam forming support, are permitted.

Combining Doka table systemsBecause the superstructures of all Doka floor-slab systems share the same basic structure, they can also be used together on the site.

Dokamatic and Dokaflex tablesThe Doka tables are pre-assembled, and save on both labour and crane time. With the shifting trolley plus attachable drive unit, the tables can easily be wheeled across to their next location by just one man working on his own. The system is optimised to give the very shortest forming-times on large areas, and copes well even with varying structural-design and geometrical requirements.

Doka XtraThis value-for-money, high-speed system has a pre-defined stripping sequence which boosts effi-ciency and evens out the site crew's workload. Any type of form-facing can be used, enabling all archi-tectural wishes regarding the concrete surface to be met.

For more information, see the User Informa-tion booklets "Dokamatic table" and "Dokaflex table".

For more information, please see the User Information booklet "Doka Xtra".

Reshoring props, concrete technology and striking

When is the best time to strike?In the building construction field, the load occurring during pouring (i.e. the weight of the uncovered floor) will generally be approx. 50% of the design load of the floor-slab (dead weight + flooring + serv-ice load).This means that the formwork can be struck once the concrete has reached 50% of its 28-day strength. The loading safety of the floor-slab is then equal to that of the finished structure.

Why put up reshoring props after

striking the formwork?Depending on the construction sequence, reshor-ing props may be needed to carry service loads on the new floor-slab, and/or concreting-loads from the next floor to be poured.

Positioning the reshoring props cor-

rectlyReshoring props have the job of spreading loads between the new floor-slab and the floor beneath it. This load distribution will depend on the relation-ship between the rigidities of these two floor-slabs.

The required numerical relationship between reshoring props and formwork props can be stated for the following two limit cases:● only approx. 0.4 reshoring props per formwork

prop where both floor-slabs have similar rigidi-ties

● only approx. 0.8 reshoring props per formwork prop where the floor-slab below has a considera-bly higher rigidity (foundation slab).

Strength development in the new

concreteThis diagram shows the strength development where different grades of cement are used. The pre-condition here is that there is an average tempera-ture of 20°C in the concrete during the curing period.

Water/binding-agent (cement) ratio = 0.50

Deflection of the new concreteThe modulus of elasticity of the concrete has already reached more than 90 % of the 28-day value after only 3 days, regardless of the formulation of the concrete. The increase in the elastic deforma-tion taking place in the new concrete is thus only negligible.The creep deformation, which only finally ceases after several years, is several times more than the elastic deformation.However, early striking - e.g. after 3 days instead of 28 - only leads to an increase in the total deforma-tion of less than 5 %.The part of this deformation accounted for by creep deformation, however, may be anything between 50 % and 100 % of the standard value, due to such variable influences as the strength of the aggre-gates, and the atmospheric humidity. This means that the total deflection of the floor-slab is practi-cally independent of the time at which the form-work was struck.

☞ Important note:

If the load is not removed from the floor props at this stage, they will remain loaded with the dead weight of the floor-slab.When the floor above is concreted, this may lead to a doubling of the load that is being applied to the floor props.

The floor props are not designed to cope with such an overload, and the result may be damage to the formwork, the floor props and the structure.

☞ Ask an expert!

As a rule, the question of using reshoring props should be referred to the responsible experts, regardless of the information given above. If there is any doubt, particularly where dissimilar floor systems are involved, the decision must be referred to the respon-sible structural designer.

Cracks in new concreteThe bonding strength between the reinforcement steel and the concrete develops more rapidly in the new concrete than does its compressive strength. This means that early striking does not have any negative influence upon the size and distribution of cracks on the tension side of reinforced concrete constructions.Other cracking phenomena caused by e.g. shrink-age, premature striking, impeded deformation etc. can be countered effectively by appropriate curing methods.

Curing of new concrete

New site-placed concrete is exposed to influences which may cause cracking and slow down its strength development:● premature drying● over-rapid cooling in the first few days● excessively low temperatures or frost● mechanical damage to the surface of the con-

crete● etc.The simplest precaution is to leave the formwork on the concrete surface for longer. As well as the famil-iar extra curing measures, this measure should be carried out in any case.

Striking the formwork from wide-

spanned floor-slabs with support centres of over 7.5mIn the case of thin, wide-spanned concrete floor-slabs (e.g. in multistorey car parks), the following points must be remembered:When the formwork is removed from beneath these floor-slab spans (i.e. when the load is taken off the floor props), the floor props that are still in place are briefly subjected to additional loads. This may lead to overloading, and to the floor props being dam-aged.When planning and designing floor formworks for these very thin concrete floor slabs, it is thus essen-tial to allow for the loads occurring during form-work removal, as well as for the usual design loads.Please consult your Doka technician.

l ... Effective floor-slab spans of 7.50 m and over

☞ The basic rule is:

The formwork should be removed starting from the middle of the floor slab (i.e. from mid-span), and working towards the edges. For wide spans, this procedure MUST be fol-lowed!

Formwork planning with Tipos

Tipos-Doka helps you to form even

more efficientlyTipos has been developed to assist you in planning the use of your Doka formwork. For wall formwork, floor formwork and platforms, it puts the same tools into your hands that we at Doka use our-selves for formwork planning.

Easy to use, fast and accurate

resultsThe easy-to-use interface makes for very fast work-ing. From when you input your layout (with the "Schal-Igel"® on-screen assistant), all the way through to when you manually put the finishing touches to the formwork solution the program gives you. All this saves time - yours.The program contains a large number of templates from formwork practice, so you can be sure of always getting the optimum technical and econom-ical solution to your formwork task. This makes for greater operational reliability, and cuts costs.You can get to work right away with the piece-lists, plans, views, sections and perspective drawings that the program gives you. Operational reliability is also enhanced by the high level of detail of the plans.

Formwork drawings really can be as clear and detailed as this! Both for the layout and for spatial representations, Tipos-Doka sets an impressive new standard of visual presentation.

Always the right quantities of form-

work and accessories

You can import the automatically generated piece-lists into many other programs for further processing.

Formwork components and accessories that have to be organised at short notice, or replaced by improvisation, are the ones that cost the most. This is why Tipos-Doka offers complete piece-lists that leave no room for improvisation. Planning with Tipos-Doka eliminates costs before they have a chance to even arise. And your depot can make the best possible use of its stocks.

Doka customer training

Formwork training pays

Forming operations account for the lion’s share of labour costs on concrete construction sites. Modern formwork equipment helps to rationalise opera-tions. By improving the overall construction sequence at the same time, however, further very worthwhile gains in efficiency can be achieved.This requires not only better equipment, but also greater skill in making optimum use of this equip-ment. Doka can help here, with its specialist train-ing programme - to help each and every member of the team do his bit towards boosting efficiency and lowering costs.Doka customer training events also look at the formwork equipment and handling methods that are needed in order to achieve optimum safety - knowledge and awareness which can only enhance workplace safety on the site.You’ll find the Doka training programme well worth looking into.

Your nearest Doka branch will be pleased to tell you more about Doka's various training offerings.
