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 booklet!
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 calculations must be produced for checking, as well as supplementary assembly instructions.

erected and dismantled, reset and generally used for its intended purpose in accordance with the applicable laws, Standards and rules, under the direction and supervision of suitably skilled persons. 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 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 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 s whenever the construction operations require (particularly after exceptional events such as storms), and to tighten them if necessary. It is strictly forbidden to weld Doka products – in particular anchoring/tying components, suspension components, connector components and castings etc. – or otherwise subject them to heating. Welding causes serious change in the microstructure of the materials from which these components are made. This leads to a dramatic drop in the failure load, representing a very great risk to safety. The only articles which are allowed to be welded are those for which the Doka literature expressly points out that welding is permitted.

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 Doka for advice first. The equipment/system must be assembled and erected in accordance with the applicable laws, Standards and rules by suitably skilled personnel of the customer's, having regard to any and all required safety inspections. It is not permitted to modify Doka products; any such modifications constitute a safety risk.
Closing the formwork ▪ Doka products and systems must be set up so that all loads acting upon them are safely transferred!
Pouring ▪ Do not exceed the permitted fresh-concrete pres-
sures. Over-high pouring rates overload the formwork, cause greater deflection and risk breakage.
Stripping out the formwork ▪ Do not strip out the formwork until the concrete has
▪
▪
reached sufficient strength and the person in charge has given the order for the formwork to be stripped out! When stripping out 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 stripping out 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!

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 booklet!

Introduction
Information Timber formwork beams
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!
Rd Rd
Design value of the resistance (R ... resistance; d ... design) Design capacity of cross-section (VRd, NRd, MRd) Rk Rk Timber: Rd = kmod · Steel: Rd = M M
Rk
Characteristic value of the resistance e.g. moment resistance to yield stress
M
Partial factor for a material property (in of material; M...material) e.g. for steel or timber Values from EN 12812
kmod
Modification factor (only for timber – to take 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: F = 1.5 M, timber = 1.3 M, 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.

Instructions for assembly and use Doka beams and Doka formwork beams can be used only as formwork beams for floor and wall formwork and only when subjected to the loads occurring in situations of direct for floor or wall formwork in structural concreting, but not for higher individual loads (e.g. safety beams). Practical example
9768-200-01
In order to maximise durability, it is important to handle the components with due care; this applies particularly when stripping out floor-slab formwork. You will also find information on correct usage in the in information for the individual products, for example: ▪ Large-area formwork Top 50 ▪ Dokaflex ▪ Doka Xtra To prevent any staining of the concrete from direct with new formwork beams, we recommend covering the formwork beams with a non-woven fabric.

All persons working with the product described herein must be familiar with the contents of this booklet 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. Information booklets, Instructions for Assembly and Use, Operating Instruction manuals, plans etc.) are available to all s, 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, s are obliged to ensure compliance with national laws, Standards and rules throughout the entire project and to take appropriate additional or alternative workplace safety precautions where necessary.

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 booklet!
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 calculations must be produced for checking, as well as supplementary assembly instructions.

erected and dismantled, reset and generally used for its intended purpose in accordance with the applicable laws, Standards and rules, under the direction and supervision of suitably skilled persons. 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 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 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 s whenever the construction operations require (particularly after exceptional events such as storms), and to tighten them if necessary. It is strictly forbidden to weld Doka products – in particular anchoring/tying components, suspension components, connector components and castings etc. – or otherwise subject them to heating. Welding causes serious change in the microstructure of the materials from which these components are made. This leads to a dramatic drop in the failure load, representing a very great risk to safety. The only articles which are allowed to be welded are those for which the Doka literature expressly points out that welding is permitted.

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 Doka for advice first. The equipment/system must be assembled and erected in accordance with the applicable laws, Standards and rules by suitably skilled personnel of the customer's, having regard to any and all required safety inspections. It is not permitted to modify Doka products; any such modifications constitute a safety risk.
Closing the formwork ▪ Doka products and systems must be set up so that all loads acting upon them are safely transferred!
Pouring ▪ Do not exceed the permitted fresh-concrete pres-
sures. Over-high pouring rates overload the formwork, cause greater deflection and risk breakage.
Stripping out the formwork ▪ Do not strip out the formwork until the concrete has
▪
▪
reached sufficient strength and the person in charge has given the order for the formwork to be stripped out! When stripping out 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 stripping out 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 booklet!

Introduction
Information Timber formwork beams
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!
Rd Rd
Design value of the resistance (R ... resistance; d ... design) Design capacity of cross-section (VRd, NRd, MRd) Rk Rk Timber: Rd = kmod · Steel: Rd = M M
Rk
Characteristic value of the resistance e.g. moment resistance to yield stress
M
Partial factor for a material property (in of material; M...material) e.g. for steel or timber Values from EN 12812
kmod
Modification factor (only for timber – to take 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: F = 1.5 M, timber = 1.3 M, 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.

Information Timber formwork beams
Instructions for assembly and use Doka beams and Doka formwork beams can be used only as formwork beams for floor and wall formwork and only when subjected to the loads occurring in situations of direct for floor or wall formwork in structural concreting, but not for higher individual loads (e.g. safety beams). Practical example
9768-200-01
In order to maximise durability, it is important to handle the components with due care; this applies particularly when stripping out floor-slab formwork. You will also find information on correct usage in the in information for the individual products, for example: ▪ Large-area formwork Top 50 ▪ Dokaflex ▪ Doka Xtra To prevent any staining of the concrete from direct with new formwork beams, we recommend covering the formwork beams with a non-woven fabric.

Transporting, stacking and storing
☞
Protect stacked beams from extreme climatic influences such as exposure to sunshine or moisture by covering them (with breathable tarpaulins). This reduces cracking. Only cover them – never envelope them completely.
➤ Always sort beams for stacking, in other words do not stack beams N and P together in a mixed stack. P

be adequately firm and level. Best-case conditions are concreted or paved storage areas. Storage on asphalt: Depending on the parts stored, place wooden battens, strips of formwork sheeting or metal sheet between the parts and the asphalt surface to ensure that the weight is adequately spread. Storage on other surfaces (sand, gravel...): Adopt suitable measures for storage (e.g. place thick plywood sheets underneath the loads).

Reprocessing scrap material Doka formwork beams contain no wood preservatives and, consequently, they can be deposited for reprocessing. Reprocessing by incineration in suitable incineration plants is recommended. It is advisable not to attempt to burn scrap material in open fires or domestic woodburners. Always comply with the applicable local or national regulations.
