User target groups

Planning

● This User Information booklet (Method Statement) is aimed at everyone who will be working with the Doka product or system it describes. It contains information on the standard design for setting up this system, 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 contains. ● Persons who are incapable of reading and understanding 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 Information 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. ● In the relevant technical documentation and formwork 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 appropriate additional or alternative workplace safety precautions where necessary.

● Provide safe workplaces for those using the formwork (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 calculations must be produced for checking, as well as supplementary assembly instructions.

Hazard assessment ● The customer is responsible for drawing up, documenting, implementing and continually updating a hazard assessment at every job-site.

This document serves as the basis for the site-specific hazard assessment, and for the instructions given to users on how to prepare and utilise the system. 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.

Any safety accessories not shown in these illustrations must still be used by the customer, in accordance with the applicable rules and regulations. ● Further safety instructions, especially warnings, will be found in the individual sections of this document!

4

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.

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 documentation 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 warnings and loading data must all be strictly observed and complied with. Failure to do so can cause accidents 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 distance away from the formwork. ● The work must take account of the weather conditions (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 functioning correctly.

It is very important to check all screw-type connections and wedge-clamped joins whenever the construction operations require (particularly after exceptional events such as storms), and to tighten them if necessary.

Introduction

Assembly

Regulations; industrial safety

● 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.

● 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.

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 pressures. 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 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 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 relevant sections of this User Information booklet!

Instruction as required by EN 13374: ● If a person or object falls against, or into, the edge protection system and/or any of its accessories, the edge protection 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. Repairs may only be carried out by the manufacturer or authorised facilities.

Introduction

User information Doka dam formwork

Eurocodes at Doka In 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 Standards 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" (comparing 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!

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

Introduction

Product description Doka dam formwork - the formwork system for mass concrete structures On mass concrete structures, it is not normally feasible to place form-ties through to the opposing formwork.

For this reason, the pressure of the fresh concrete has to be transferred into the previous concrete block. Doka dam formwork ensures that the forces which occur here are transferred safely and reliably.

Areas of use: ● Dams and barrages ● Run-of-river power stations ● Navigation locks The formwork and dam scaffold are lifted to the next casting section in one single crane cycle.

2 systems For optimum adaptation to every construction project, Doka offers two different dam formwork systems, both of which always use the same method of working:

Dam formwork D15 for anchor tensile forces of up to 150 kN ● Dam formwork D15 K - for block heights of up to 3.0 m - formwork is tiltable ● Dam formwork D15/3 - optimised for a block height of 3.0 m - formwork is tiltable, and can also be modified to make it retractable

The dam scaffold can be fitted with various different formwork systems, e.g.: ● Large-area formwork Top50 ● Framed formwork ● Steel formwork

Dam formwork D22

☞

● Dam formwork D22 K - formwork is tiltable ● Dam formwork D22 F - formwork is retractable

The Doka dam formwork system is extremely flexible. For this reason, detailed planning and static calculations are required for every single project.

- for block heights of between 3.0 and 4.0 m for anchor tensile forces of up to 220 kN

Dam formwork D15 K and D15/3 Dam formwork D15

Doka dam formwork D15 is used for forming block heights of up to 3 m. The Dam scaffold D15 can sustain anchor tensile forces of up to 150 kN. The formwork can be tilted backwards to leave enough space for preparing the suspension points.

Doka dam formwork D15 is easy to adapt to sloping wall surfaces and to kinks in the walls.

2 versions Dam formwork D15 K When tilted backwards, the formwork leaves plenty of space for preparing the suspension points. The platforms are a generous 1.7 m wide, making it easy to operate the spindle strut.

Dam formwork D15/3 The Dam formwork D15/3 is the optimum dam scaffold for block heights of 3.0 m. Its 2.2 m wide platforms allow great freedom of movement.

The Dam formwork D15/3 can easily be modified to equip it with a travelling unit. This makes the formwork retractable as well.

Anchoring in the base slab

☞

As a basic rule: The anchoring arrangements for the starter-block formwork are always dimensioned on a project-specific basis.

● The loads from the diagonal anchors are transferred via anchor walings (E) . ● The tie-rod 15.0mm and the super-plate 15.0 (F) together secure the anchor waling so that it cannot tilt or slip out of position. ● For each starter-block unit, two anchors are each placed 15 cm either side of the vertical axis of the starter-block unit.

Exception: If the load-bearing capacity is sufficient for 1 anchor per starter-block unit, the anchors on each unit must be placed symmetrically.

Both the positioning points and the suspension points are prepared using one single type of cone, the Universal climbing cone (A) .

The Cone screw B 7cm (C) also fulfils 2 functions: ● On the positioning point - for fastening the Universal climbing cone. ● On the suspension point - as a safe means of suspending the cantilever bracket.

Preferably, pigtail anchors (D) are used, or - depending on the characteristics of the structure - stopanchors (F) .

Dimensioning the suspension point The required cube compressive strength of the concrete at the time of loading must be specified separately for each project by the structural designer. It will depend on the following factors: ● the tensile force actually occurring ● length of stop-anchor or pigtail anchor ● distance from edge The introduction of the forces, the transfer of these forces into the structure, and the stability of the overall construction, must all be verified by the structural designer.

WARNING - against not screwing the pigtail anchor or stop anchor far enough into the Universal climbing cone.

This may subsequently lead to reduced loadbearing capacity and to the failure of the suspension point - resulting in injury and damage. ➤ Always screw in components until they fully engage (i.e. up to the depth mark).

CAUTION ➤ For the positioning point and suspension point, ONLY use Cone screws B 7 cm (head of screw is red, to indicate its high load-bearing capacity)! ➤ The axis of the cantilever bracket and the axis of the Universal climbing cone must align - maximum angle-deviation 2°. ➤ Every time the Universal climbing cones are used, fit them with new sealing sleeves first.

WARNING Sensitive rod steel! ➤ Never weld or heat tie-rods. ➤ Tie rods that are damaged or have been weakened by corrosion or wear must be withdrawn from use. ➤ Only use approved tie-rods.

Tools needed: ● Reversible ratchet 3/4" ● Spanner for Universal climbing cone 15.0/20.0 ● Box nut 50 3/4"(for Cone screw B 7cm)

The required cube compressive strength fck,cube,current must be at least 10 N/mm2, however.

On dam projects using concretes that have been specifically tailored to the project, the required length of the pigtail anchors must be determined in on-site trials (regarding concrete strength, type of concrete etc.).

Form-ply protection The "Form-ply protector for cone 15.0" protects the form-ply from damage around the positioning-point.

This is a particular advantage for formwork with high numbers of repeat uses.

Possible thicknesses of form-ply: 18 - 27 mm In order to fit the Form-ply protector, a 46 mm diam. hole must be drilled in the form-ply first.

Note: Universal climbing cones are supplied with Sealing sleeves K (B) . Every time the Universal climbing cones are used again, fit them with new sealing sleeves first!

☞

Important note: The cone-fixing method that involves drilling through the form-ply is the one that is most suitable for the working conditions encountered on dam construction sites.

If the large size of the drilled hole makes it impracticable to use the Cone screw B 7cm for the positioning-point, (e.g. if the suspension points are often not in the same position as in the previous casting section), then the Positioning clamp M30 must be used (hole diam. = 9 mm).

The cone should only be fixed with the Positioning disc M30 in exceptional situations!

However, in this case additional precautions must be taken to ensure that it is not dislodged from its exact installation location during pouring!

Plumbing & aligning the formwork Length adjustment

Adjusting the formwork In order to permit exact adjustment of the formwork elements in relation to one another and to the structure, they are adjustable in both the vertical and the horizontal.

☞

➤ Push the formwork to either side.

To make it possible to compensate for any deformations during pouring, the formwork should be adjusted with a forward inclination.

The extent of this forward inclination (see project plan) will depend on the following factors: ● Block height ● Pressure of the fresh concrete ● Influence width per parallel frame section

Tools needed: ● Hammer ● Reversible ratchet 1/2" ● Box nut 24 1/2" and ● Fork wrench 22/24 (for the threaded joins on the adjusting spindles)

CAUTION There is a risk of the formwork tipping over in high winds. ➤ If high wind speeds are likely, and when work finishes for the day or before prolonged work-breaks, always take extra precautions to fix the formwork in place.

Suitable precautions: Move the formwork up against the concrete and wedge it firmly against the concrete.

9706-210-02

Height adjustment ➤ Turn both adjusting spindles.

For more information (wind loads etc.) see the section headed "Vertical and horizontal loads" in the Doka Calculation Guide.

Press the formwork to the concrete For clean, exact concrete surfaces and transitions, the formwork element must be pressed very tightly against the previous section.

This can be done quickly and easily with the pressure wedge of the swivel bearing plate. ➤ After adjusting the formwork elements, tighten the pressure wedges (A) .

This presses the formwork element up against the previously cast section.

Resetting by crane

☞

Important note: ● Observe all regulations applying to the operation of cranes where higher wind speeds are experienced. ● Only fasten the crane-cable hook to the suspension bolt (A) of the vertical waling.

The crane-hoisting lugs on the formwork elements must not be used for lifting the formwork unit. ● Angle of inclination β: max. 30° ● Brace the vertical waling sufficiently against oblique pull (B) .

Tightening torque of the couplers (C) : 50 Nm ● Bring the travelling unit as close to the centre-of-gravity position as possible, and secure the Swivel bearing plate with the Swivel bolts. ● If lifting past sloping walls, fasten an overhanging lifting device to the vertical waling.

Where the formwork is inclined forward, check whether a tension guy-bracing chain is needed. ● When a single dam formwork unit is lifted, two open ends are left in the formwork system. These must be secured by mounting side protection (e.g. Handrail clamp S).

Structural design The cantilever centres are computed from various different influences: ● Pressure of the fresh concrete ● Block height ● Angle of inclination of formwork ● Wind loads

☞

Allow for the following when performing the structural design calculations: The formwork used must be dimensioned as required by the cantilever centres (e.g. the correct steel walings must be selected).

Max. service load of the working platform: 1.5 kN/m2 (incl. loads occurring as a result of pouring)

This is why dam formwork must always be dimensioned on a project-specific basis.

When determining the pressure of the fresh concrete, allow for the following: ● Additional loads from concrete spreading devices (e.g. caterpillar concrete spreader). ● Slow setting of the concrete (fly-ash)) ● Low concrete temperature (cooled concrete) ● Low proportion of cement in the concrete

Determining the cantilever centres for perpendicular formwork* * Formwork and cantilever bracket perpendicular and in one plane (no kink in wall)

Ready-to-use formworks - for even the most unusual assignments

Formwork training pays

Whatever it is you need to construct from concrete, the Doka Ready-to-Use Service can put together the right formwork for you - quickly, and in guaranteed Doka quality.

The professionals from the Doka Ready-to-Use Service plan and make ready-to-use standard and custom formworks exactly to your specifications.

By delivering "just-in-time", straight to your site, we save space on your site and reduce the amount of planning and assembly work that you have to do.

Pre-assembled platform decking reduces assembly times The pre-assembled platform decking has many advantages: ● Pre-assembly in the factory or at the depot helps to cut costs. ● Operations scheduling ensures efficient assembly. ● High precision ensured by use of assembly bench. ● No space problems. ● No need for on-site improvisation. ● Reduces assembly times on the site. ● Cantilever brackets are quickly ready for use. ● Low transport volume.

Forming operations account for the lion’s share of labour costs on concrete construction sites. Modern formwork equipment helps to rationalise operations. 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 equipment.

Doka can help here, with its specialist training 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.
