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!

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

Symbols used

● Doka products and systems must be set up in such a way that all loads acting upon them are safely transferred!

The following symbols are used in this booklet:

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!

● If a person or object falls against, or into, the sideguard component and/or any of its accessories, the 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.

☞

Important note Failure to observe this may lead to malfunction or damage.

CAUTION / WARNING / DANGER Failure to observe this may lead to material damage, and to injury to health which may range up to the severe or even life-threatening.

Instruction This symbol indicates that actions need to be taken by the user.

Sight-check Indicates that you need to do a sight-check to make sure that necessary actions have been carried out.

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!

Tip Points out useful practical tips.

Reference Refers to other documents and materials.

Miscellaneous We reserve the right to make alterations in the interests of technical progress.

Introduction

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!

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

γM

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 permissible values. 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

User information Doka form-ties for special requirements

Preliminary remarks To pour walls, it is necessary to have wall-ties with sufficient load-bearing capacity. In general, a distinction is made between: ● wall-ties where no special requirements are made – these only need sustain the pressure of the fresh concrete – and ● wall-ties for special requirements that are fulfilled by additional measures aimed at making the tie-points e.g.: - water-impermeable - fire-resistant - sound-insulating - gas-impermeable - radiation-proof This manual offers ideas and suggested solutions for form-tie points that need to meet one or more of the requirements stated above. General remarks: ● Choosing a suitable formwork system with a widely spaced form-tie pattern is one way of reducing the number of expensive wall-ties that are needed. This will, of course, depend upon the circumstances and requirements applying on each site. ● If the main sealing function is intended to be in the middle of the wall (in the same way as with joint-sealing tape), this has the advantage that the form-tie point is watertight from the moment the formwork is stripped. ● Sealing measures that are carried out on the outside only, e.g. by bonding, call for extremely skilled, painstaking work. ● Tie-holes with small conical openings are more pleasing to the eye (fair-faced concrete) and easier to close off. ● In order to ensure that the wall-tie fulfils the requirements made of it, the points below must be followed, regardless of which design variant is selected: - the wall-tie must be precisely defined in the tendering documents - the relevant regulations and Standards must be observed - the manufacturer's installation instructions must be followed - the personnel involved must be sufficiently skilled

Water-impermeable concrete, and the wall-ties used in it

Concrete with high water-penetration resistance (watertight concrete without any extra sealing layers), has been in use for many years now. When it comes to manufacturing and casting watertight concrete, there is plenty of good, detailed literature with references to DIN regulations etc. Watertight form-ties, on the other hand, do not receive anything like as much attention in the pertinent Standards. ● Recent investigations have shown that the depth of water penetration into watertight concrete is only approx. 7 cm Source: "Feuchtetransport durch Bauteile aus Beton" (Moisture transmission through concrete structural components) in "Beton- und Stahlbetonbau" (Concrete and reinforced concrete construction), 4 1999 d a

"Water-impermeable" means that more water vaporises from the side facing away from the water pressure than penetrates into the side which is exposed to it. 10

999779002 - 05/2011 The Formwork Experts

User information Doka form-ties for special requirements

Form-tie points for special "dry" applications The sealing techniques for fireproofing, acoustic insulation, radiation protection etc. are mostly similar to those for creating water-impermeable form-tie points, and use the same components.

Fitting the wall-tie The properties set out in the test report can only be attained if the following conditions are met: ● only undamaged and clean components are used ● the components are only fitted by trained, skilled personnel ● all the relevant installation instructions are followed

☞

● Do not unscrew form-ties prematurely (in "green", i.e. new, concrete) or with violent hammer-blows. This would break the adhesion between the tie-rods and the concrete in which they are embedded, and might mean that the form-tie point is no longer watertight.

Introduction

Minimum wall thicknesses The wall thickness will be determined by the function that the structure will have to fulfil. The following practical site-related factors may necessitate a larger wall thickness: ● the type of reinforcement ● the concrete-placement method (be careful regarding drop heights and de-mixing) ● the type of compaction (internal or external vibrators) In practice, the wall thickness will already have been decided. If the thickness stipulated is not ideal, then a suitable approach will need to be taken to tackling this situation. Wall thickness required for placing the concrete by drop-pipe in accordance with the regulations a B

Concrete and concrete placement In order for concrete structures to be cast in such a way that they fulfil architectural specifications, properly prepared wall-ties have to be combined with careful placing of the concrete. ● the concrete must be defined in accordance with the requirements - bid description to EN 206-1:2000 ● attention must be paid to the quality of concrete placement - vibration, weathering, concrete-placement method etc.

Tender documents It is on the basis of the tender documents that the most suitable design variant will be chosen ("suitable", that is, in terms of the use to which the structure will later be put). All the variants outlined must make clear what additional work / costs will be involved, and the care that will need to be taken. It is advisable to give detailed descriptions of sizes, materials, fitting instructions and problem points. Also, there are several different design variants, as outlined in the following sections.

● Always use fibre-concrete tubes of the same length – otherwise the formwork cannot be closed cleanly, and laitance may penetrate into the Universal cones, making it difficult to remove them. ● Keep fibre-concrete tubes well away from release-agent. Also, do not wear releaseagent-smeared gloves when fitting them. Otherwise, the in-situ concrete will not bind sufficiently tightly to the tubes. ● Thoroughly moisten the fibre-concrete tubes before pouring. ● Time any interruptions to placement correctly.

➤ Then insert the second plug, after dipping it into the glue in the same way. Push it in until it is flush with the end of the tube, then spread the rest of the glue.

Cleaning the centre-hole ➤ e.g. with a round brush or a drill bit. The fibre-concrete tubes should be as dry as possible; any water must be removed. If the plugs will not fit into the tube because cement paste has run into the opening and dried, this can be drilled out with a Widia drill bit. Specially short drill bits with exactly calibrated diameters are available for this job. Mixing the REPOXAL two-component glue ➤ Completely empty the contents of the hardener pot into the can of REPOXAL glue. Thoroughly mix the hardener and the glue to make a completely homogeneous mass.

Sealing the tubes with plugs ➤ Always start fitting the plugs on the side of the wall exposed to water pressure. Wherever possible, wear gloves when fitting the plugs. Any glue that gets onto your hands can be cleaned off with spirit or thinner. After this, wash your hands thoroughly with water and soap. ➤ Dip the first plug into the glue and briefly rotate it in the glue so that its entire circumference is wetted. Now push in the plug with the tamping tool until the top of the plug is approx. 5 mm inside the fibre-concrete tube.

➤ Now these plugs should be left for several hours so that the glue can harden before the end of the tube facing away from the water-pressure is closed off with plugs in the same way. If you do not leave sufficient time for the glue to set, the air being compressed inside the tube may push out or loosen the plugs at the first end of the tube.

☞

9779-202-02

If a hydrostatic pressure test is intended, this should be performed with only the two plugs on the water-pressure side inserted – i.e. before the plugs on the other side have been fitted. After the plugs have been inserted on the water-pressure side, the glue must be allowed to set. The waiting time is highly temperaturedependent. For the structure temperatures given below, it will be as follows: ● 20°C – approx. 10 days ● 10°C – approx. 24 days ● 5°C – approx. 40 days After the end of this waiting time, the tank or vessel (for example) can be filled. Once any pressure test has been carried out, the end of the tube facing away from the waterpressure can be closed off with two plugs as described above.

REPOXAL two-component glue

How to use REPOXAL two-component glue is used for plugging fibre-concrete tubes. Product description Owing to its chemical composition, REPOXAL twocomponent glue reacts with the REPOXAL hardener. This chemical reaction results in a hard, watertight, chemical-resistant adhesive. Pot life The ready-mixed adhesive remains workable for max. 4 hours at 20°C. Setting time At temperatures of 20°C, the glued plugs can be subjected to gentle loading after 48 hours, and to normal loading after 96 hours. Higher temperatures shorten the pot-life and the reaction times, while lower temperatures prolong them. At temperatures below +5°C, no chemical reaction takes place and the glue cannot set. For this reason, do not attempt to use the glue at temperatures below +5°C. The temperatures given here always refer to the temperature of the building component. Yield For 1000 plugs, each 2 cm long, the following quantities of REPOXAL two-component glue will be consumed: ● Ø 22 mm - approx. 3 kg ● Ø 27 mm - approx. 4 kg ● Ø 32 mm - approx. 5 kg ● Ø 40 mm - approx. 7 kg Resistance REPOXAL two-component glue is resistant to tap water, seawater, waste water in sewage treatment plants and water containing ozone or chlorine used in swimming pools. In addition, loading tests have been carried out with a wide variety of agents, to which REPOXAL two-component glue has been proven resistant.

Closing off the form-tie point In its technical bulletin entitled "Fair-faced concrete", the DBV (German Concrete Association) recommends leaving cone indentations as they are. This is because attempts to grout them level with the rest of the surface normally produce unsatisfactory results (colour differences, grouted areas have unclean edges).

☞

If it is still necessary to close off the form-tie point, for rust protection reasons (tie-rod), we recommend gluing in a fibre-concrete plug. The job of closing off the form-tie point should only be carried out by reliable skilled workers or competent subcontractors.

Example with fibre concrete plug We recommend the following materials for gluing in the plugs: ● Commercially available cement mortar, e.g. repair and renovation mortar, watertight exterior grouting compound etc. Pay attention to the colour of the concrete here! ● Tile bonding cement (is mostly dark) in cases where the colour of the concrete is unimportant. ➤ Evenly distribute the mortar mixture in the conical opening and then slowly press the Fibre concrete plug 54mm (K) into the opening while gently turning it. (Using a piece of wood makes it easier to fit the plug on the right plane).
