Introduction User information Doka load-bearing tower Staxo 100

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.


5999800302 - 06/2008 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

Introduction User information Doka load-bearing tower Staxo 100

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 action Steel: Rd =Rk Timber: Rd = kmod

RkFd = F Fk M M(F ... force)

Fk Characteristic value of an action"actual 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

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

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

Load-bearing tower Staxo 100 the extra-high-capacity, fast load-bear-ing tower made of steel, with inte-gral safety featuresStaxo 100 comes with all the field-proven advan-tages of Staxo meaning that it is robust, fast and versatile. On top of all this, Staxo 100 has been given an extensive package of built-in safety fea-tures, and its load capacity greatly increased.Sturdy galvanised steel frames, in three different heights, are the basis of this high-speed, high-per-formance load-bearing tower system.High load-bearing capacity, quick and easy assem-bly using integrated connectors, and great versatil-ity - these are the outstanding characteristics of Staxo.Wherever high loads occur, in either the building-construction or civil-engineering fields, this load-bearing tower is the ideal solution.

The high-performance load-bearing tower

high capacity of up to 97 kN per leg with lightweight components (frames up to

h=1.20 m can be manhandled) ergonomical: easy-to-handle parts

... speeds up work

the small number of system components makes for easier handling and means that no time is wasted searching for parts

the connector components are captively inte-grated into the frames and so cannot be lost

no tools are needed for assembling the towers

... provides optimum safety

high stability, due to its 1.52 m wide frames slip-proof ladders integrated in the frames suspension points for chest harness

... is flexible

the inter-frame spacing can be varied (from 0.60 m to 3.00 m), for optimum utilisation of the frames' load-bearing capacity. (From 1.00m, in 50 cm increments).

different frame heights - 0.90 m, 1.20 m and 1.80 m - for rough height adjustment in 30 cm increments: 0.90, 1.20 and 1.80 m

fine adjustment by means of screw-jack U-heads and feet

can be used in conjunction with floor props and Dokaflex

... is economical

The tower units are quick and easy to assemble:- either on their sides or in the upright- for tall towers, tower units can be pre-assem-

bled on their sides, and then simply stacked by crane

- clip-on assembly battens make it easy to erect and dismantle the tower and the superstruc-ture

with special wheel units, complete tableforms can quickly be wheeled to their next location

the Forklift shifting device TG makes the job of erecting, dismantling and transporting Doka load-bearing towers very much easier.

User information Doka load-bearing tower Staxo 100 System description


Areas of useThe Load-bearing tower Staxo is ideal: as falsework for use in bridge-building, where

high loads occur and where great stability is called for in that horizontal forces such as wind loads have to be safely transferred

in the building construction field, e.g. for admin-istration buildings and multistorey car-park decks, where large-area tableform units reduce forming-times

in the industrial and power-station construction field, as a load-bearing tower for all manner of applications

Doka stair tower 250The Doka stair tower 250 consists of 1.20 m frames and a small number of lightweight aluminium stair-way elements.Quick to erect, the stair tower provides "high-level" safety and lets the site crew get quickly to their workplaces.

Practical examplesTableforms and tower frames are both assembled from the same system components.

Tableform units For repetitive use, the load-bearing tower can be

assembled into complete table-forms.

Combined with DokaflexFor floor-beams, load-bearing towers and beam-forming supports can be combined very effectively with Dokaflex 1-2-4.

Edge floor-beam

Tower framesWith a load-bearing capacity of up to 97 kN per leg, Staxo 100 is an extremely strong load-bearing tower system.It safely withstands horizontal forces such as wind loads.The wide frames make for high stability right from the word "go".Close inter-frame spacing is possible, for transfer-ring high loads.

Adapts to different ground plans, heights, floor shapes and loadsThe different sizes of diagonal brace for each height of frame enable the frames to be spaced close together or further apart, depending on the load.

In this way, only as much material is used as is really needed.

Height adjustment The 3 different heights of frame (0.90 m, 1.20 m

and 1.80 m) enable coarse adjustment to within 30 cm.

Fine adjustment, down to the last millimetre, is done using the various head and base units.

Horizontal assembly

Horizontal assemblyPreliminary remark: The terms "vertical" and "horizontal" (e.g. refer-

ring to the diagonal crosses) are always used here with reference to their installation situation in the finished, upright tower.

The job of erecting the load-bearing tower begins with the bottom (i.e. first) section.

Arrow on frame must be pointing upwards.(= yellow locking spring at bottom)

Erecting the first section Having regard to the instructions given above,

place the tower frames on their sides on timber supports (min. 4cm high).

Bracing the frames in the vertical Link the frames with diagonal crosses (F) .

Plan-bracing the frames (in the horizontal)

Slot diagonal crosses (K) onto the gravity latches of the horizontal frame tubes and secure them.

Press the yellow locking springs (E) on the frame (D) inwards (to open) the connection sleeves can now be moved freely.

Push in and secure the base units. See the sec-tion headed "Lifting by crane".

General remarks: As soon as you have slotted a diagonal cross onto the latch-type peg, secure it with the safety catch.

When erecting the tower, make sure that the climbing rungs are in the right position rela-tive to the tower.

Seen from outside, the ladder must always be on the left-hand side.This makes it possible to use assembly bat-tens where needed (see "Assembling towers in the upright with mounted-ahead rail-ings").

Lifting into the upright by crane Check before attaching the crane suspension

tackle:

Lifting into the upright

Attach the crane suspension tackle to the frames of the top section and lift the entire tower into the upright.

DismantlingAfter the tower has been placed back on its side, it can be dismantled in reverse order.

All the locking springs must be closed = pushed outwards (to link the frames).

All safety catches must be closed. All base units must be secured.

Max. extension length of the base units when the tower is being lifted into the upright: 35 cm!

Important note: Erect the load-bearing tower in the verti-cal on ground that is statically capable of supporting the load.

If the load-bearing tower is over 6 m high, back-stay it or combine it with other tow-ers.

When the tower is standing in the upright, check once again to make sure that all the safety catches are closed.

Travelling the towerframe units

Assembling the towerframe units

Build each section at ground level. Use a forklift truck to stack the towerframe sto-

reys into a single towerframe unit.


Important points to remember when wheel-ing load-bearing towers: As well as the fork-lift driver, a specially

trained watchman must also be on hand during all lifting, assembly and travelling operations:

max. inclination of trackway: 2%. The floor must be stable, firm and suffi-

ciently smooth (e.g. concrete).

For details of how to assemble and join together the individual sections ("tower-frame storeys"), see "Assembling towers in the upright"!

Important note:Always only dismantle the bottom "storey" of the towerframe unit.

Accessory for transporting the winches when empty:The Double-wheeled transporter (A) is bolted into the connecting sockets on the wheel flange and makes it easier to wheel the (empty) wheel units.

Shifting carriage TGThis is an easy-to-operate, manual hydraulic lifting carriage for shifting light to medium-weight table-form units. As well as making the tableforms easier to move around, it also makes it easier to erect and strike the formwork.

Hydraulic, for near-effortless lifting. Tables can be "inched" down slowly with handle-

control. 3 guide-rolls, for maximum manoeuvrability. With an overall width of only 82 cm, the carriage

can pass easily through any doorway when empty.

Push the Shifting carriage TG (A) up against the front and rear faces of the tableform - the slot-in lifting profile (B) reaches under the bottom crossbar of the frame.

Secure the foot-pieces to prevent them dropping out. See the section headed "Lifting by crane".

Lifting by crane

Where the tableforms are to be repositioned in the vertical, i.e. crane-lifted, they must be fitted with a Lifting rod 15.0 and Retaining plate 15.0 , which make it easy to attach the transfer cables.

Mounting instructions Mount the Lifting rod 15.0 (A) and Retaining

plate 15.0 (B) .

Preparations

Connect superstructure components together e.g. connect the primary and secondary beams to

rafter plates, and nail on the form-ply.

Connect the superstructure to the head units e.g. with Locking rod 15.0 (D) , Clamping plate (E)

and Wing nut 15.0 (F) .

Secure the head units so that they cannot be lifted out Slot the fixing-handle (G) into the cross-bar of

the frame.

Secure the base units to prevent them drop-ping out: On Screw jack foot (H) and Heavy duty screw jack 70 or 130 using Split nut B Slot the fixing-handle (I) into the cross-bar of the

frame.

Important note:The max. height of towerframe unit that can be lifted in one piece is 20 m!

Max. load:1000 kg per Lifting rod 15.0 - where the load is applied centrally

Use a 20 mm diam. bit to drill the hole through the form-ply. It can later be filled with a Universal plug R20/25.

Important note:Separate proof must be provided, by a suit-ably skilled person, regarding the founda-tion. Particular attention must be paid here to the ground-bearing pressure!



Load-bearing tower held at topBasic points regarding the statical proof:1. On the basis of the extension lengths of the

screw-jacks in the base zone (LF1 and LF2), ascer-tain the relevant range A or B in Diagram 1.See the legend to Diagram 1 for details of the resulting limitations in the head zone.Range B is divided into 2 sub-ranges:- B1 ... No need to brace the spindles- B2 ... Spindles must be braced with a scaffold-

ing tube (Z) .2. Use the result obtained (Range A or B) to ascer-

tain the permitted vertical load and height of the load-bearing tower from the following Diagrams 2 to 9.

Diagram 1: Finding the applicable Range

a ... Max. eccentricity of junction or coupling: 10 cm

Practical example: Height adjustment to steps (mixture of Range B1 and B2)

Bracing-strut plane:e.g. LF1 = 25 cm, LF2 = 75 cm: B1 (no need for bracing with scaf-folding tubes)Frame plane 1: (on the right in the illustration)e.g. LF1 = 75 cm, LF2 = 75 cm: B2 (bracing with scaffolding tubes required)Frame plane 2: (on the left in the illustration)e.g. LF1 = 25 cm, LF2 = 25 cm: A (no need for bracing with scaffold-ing tubes)

Practical example: All spindles extended by more than 70 cm (all planes in Range B2)

Custom application: Load capacity up to 85 kN per leg

Height ranges and materials sched-uleChoose the right diagonal crosses for the distance between the frames.

1.20m and 0.90m frames are possible here.

Table A

The schedule of materials does not include assembly battens.

The assembly battens have to be planned separately for each set-up configuration. Provided they are located in the same level, they replace the Diagonal crosses 9.xxx needed for horizontal bracing. This reduction in the number of diagonal crosses needed must be allowed for in the schedule of materials.

The minimum values "hmin." given inTable A are only applicable if the biggest possible frame is always used in the base section.

The lowering distance of 6 cm is already allowed for in Table A!

LK and LF are in accordance with the dimensioning diagrams
