Elementary safety warnings

Symbols usedThe following symbols are used in this booklet:

MiscellaneousWe reserve the right to make alterations in the inter-ests of technical progress.Unless otherwise stated, all dimensions are given in cm.

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

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

● 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!

● Do not exceed the permitted fresh-concrete pressures. Excessively high pouring rates lead to formwork overload, cause greater deflection and risk causing breakage.

● 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 stripping the gang-form, never use the crane to break concrete cohesion. Use suitable tools such as timber wedges or a special pry-bar.

● 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!

● Observe all regulations applying to the hand-ling 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, follow-ing all the special Doka instructions given in the relevant sections of this User Information book-let!

● Further safety instructions may be found in each of the sections of this booklet!

System overview

Doka bridge edge beam formwork T-

the fast manual bridge edge beam

formwork (type-tested)This formwork is a quick and easy way of construct-ing edge kerbs on bridges. It only has a small number of separate parts, which combine high load-bearing capacity with low unit weight. This makes it possible to erect Doka bridge edge beam formwork T by hand.

Cost-effective areas of utilisation include the cast-ing of edge kerbs in the following cases:● shorter bridge superstructures (completely scaf-

folded)● medium-length bridges with a small number of

repositioning cyclesThe system is also suitable for curved bridges.

The many plus-points of Doka bridge edge

beam formwork include:

● Quick-attachment facility for the Bridge edge beam bracket

● Continuous height adjustment of the Bridge edge beam support on the Bridge edge beam bracket

● Quick-fix connection between the Bridge edge beam support and the Bridge edge beam bracket

● Wide angle-setting ranges ensure great flexibility● Components have high load-bearing capacity yet

low unit weight● Galvanised, long-life constructional design

Patents (DE 196 40 396 and AT 409 281) have been filed for the system components of the Doka Bridge edge beam formwork T.

Example using Doka forming wagon T:

A Bridge edge beam bracket T 0.80m

B Bridge edge beam support T 1.40m

C Bridge edge beam clamp T 0.40m

D Handrail post 1.00m or Handrail post T 1.80m

Instructions for assembly and use

Preconditions for use:The suspension points must be pre-fitted in the superstructure at the correct intervals (see the sec-tion headed "Suspension point with Bridge edge beam anchor").For erecting the formwork, we recommend using a mobile elevating work platform, or a personnel hoisting cage lowered from a construction crane, mobile crane or truck-mounted crane.Various types of assembly carriage for edge-kerb formwork are available on the market. Whether a particular carriage is suitable for erecting Doka bridge edge formwork T will depend upon the dimensions of the edge kerb, and must be verified separately for each project.

As the Doka bridge edge beam formwork takes only a very short time to set up, the hoisting equipment is not "tied up" here for long.

Suspending the first Bridge edge

beam bracket➤ Screw in the Screw-in cone 30 kN/15.0 (see "Sus-

pension point with Bridge edge beam anchor" for details).

➤ Mount the Bridge edge beam bracket (see "Sus-pension point with Bridge edge beam anchor" for details). This job can be made easier by lowering the Bridge edge beam bracket by cable.

➤ On the first Bridge edge beam bracket, roughly set the height of the connecting slide (see "Man-ual erection" for details)

Suspending further Bridge edge

beam bracketsBefore being suspended, all the other Bridge edge beam brackets can now be pre-adjusted to match the first bracket.➤ Screw in the Screw-in cones 30 kN/15.0 (see

"Suspension point with Bridge edge beam anchor" for details).

➤ Mount the Bridge edge beam brackets (see "Sus-pension point with Bridge edge beam anchor" for details).

Mounting the Bridge edge beam supports➤ Mount all Bridge edge beam supports T 1.40 m

and level them (see "Manual erection" for details).

Mounting the Bridge edge beam

clamp➤ Stand the Bridge edge beam clamp T 0.40m on

the support and wedge it at the required distance from the edge of the structure (see "Manual erec-tion" for details).

☞ Important note:

All equipment used must be officially approved for the conveyance of persons!

9730-243-01

9730-289-01

9730-329-01



Mounting the handrail posts➤ Slot Handrail posts 1.00m into place, and fasten

the guard-rail boards (see chapter "Manual erec-tion" for details).

➤ Lay the deck-boards (these must overlap by at least 20 cm).

Board thicknesses:● floor decking min. 20x4 cm● guard-rail boards min. 15/3 cm

Scaffold components made of timber must con-form - as a minimum - to grading category S10 (as per DIN 4074 Pt 1), and must bear the symbol "Ü!After this, no hoisting equipment is needed for any of the remaining operations.

Mounting the formworkThis is performed from the bridge superstructure on one side, and from the decking on the Bridge edge beam supports on the other.➤ Mount the bottom formwork (see "Erecting the

formwork" for details).➤ Mount the side-formwork (may be preassembled

– see "Erecting the formwork" for details).

Before pouring: Adjusting the form-

work and reducing playThe adjusting spindles of the Bridge edge beam clamps are subjected to compressive force during pouring. As the bolted connections naturally have a certain play, it is possible that some spindles will be loose (i.e. under tension) after the formwork is mounted. During pouring, this play in the spindles would result in deviations from the pre-set dimen-sions.

To prevent this effect, please observe the following points:

➤ Check whether there is any play in the spindle. If not, the adjustment is OK.If there is:

➤ Screw the spindle clockwise (to move it apart) until the play is eliminated, but not so far that the formwork is also moved at the same time.

9730-333-01

9730-292-01

☞ At the same time as checking the spindle, also check the wedge tension of the Bridge edge beam clamp.

Retrofitted suspension pointsBridge edge beam formwork T is also ideal for use in bridge renovation. However, in this area of use, ready-prepared anchoring points will rarely be found. In such cases, suspension points can be pre-pared as shown in the example below. More suspension methods are available on request!

Example using a heavy duty anchorThe HILTI heavy duty anchors HSL-3 M16/50 or HSL-3-B M16/50 (European approval ETA-02/0042) can be used for retrofitting safe suspension points for Bridge edge beam brackets T in "cracked and uncracked concrete".These heavy duty anchors are not part of the Doka product range and so must be requested directly from the manufacturer concerned.

Erecting the formwork

Side-formwork with "upright" Doka

beamsThe formwork configuration can be exactly tailored to the requirements encountered on the site.The use of upright Doka H20 beams has proved par-ticularly effective. The beams can easily be over-lapped, giving great flexibility in terms of formwork erection. The side formwork can also be pre-assem-bled and repositioned in one piece.The ready-drilled holes in the Bridge edge beam clamp make it possible to fasten the beams with e.g. square bolts M10x110 (not included with prod-uct).

Side-formwork with "flat" Doka

beamsWhere necessary, the Doka H20 beams of the side formwork can also be placed "flat on their sides".The ready-drilled holes in the Bridge edge beam clamp make it possible to fasten the beams with e.g. square bolts M10x110 (not included with prod-uct).

☞ When planning the formwork, allow for the 9.3 cm wide zone x in which clamping is not possible.Because of the spindle connection point, the clamping wedge (A) cannot be positioned in this zone.

Platforms on wide edge beams

Widening the platformA minimum distance a is stipulated between the outer edge of the formwork and the sideguard rail-ings in situations where the top of the sideguard is less than 1.0 m above the outer edge of the form-work.

In order to comply with these regulations in the case of wide edge beams, either of the following 2 methods can be used:● widening the Bridge edge beam support T 1.40m

by adding a Bridge edge beam support extension T 0.20m.

● using the Handrail post T 1.80m to widen the Bridge edge beam support T 1.40m.

Platforms on bridges over traffic routes

with the Bridge edge beam platform

T 2.70mIf bridge edge formwork is erected above public transportation routes (roads, waterways, railways) then an enclosed platform (protective canopy) will also be required, to prevent any objects dropping onto the route beneath. The Bridge edge beam platform T 2.70m (D) is avail-able for this purpose.Rough angle adjustment is possible by means of a hole grid (H) .

☞ First mount the Bridge edge beam platform T 2.70m (D) ,and only then hang the Bridge edge beam support T 1.40m (B) into place.

For design data, please see the section headed "Extended system" in the type test for "Bridge edge beam formwork T".

e.g. for spark arrester platforms

The Doka bridge edge beam formwork T is extremely flexible. For example, it can also be used - without difficulty - for spark arrester platforms, as required on bridges crossing electrified railway lines.These must be dimensioned on a project-specific basis.

Additional precautions needed for solid (i.e.

gap-free) boarding

The rules may require solid (i.e. gap-free) boarding to be fitted to the Handrail posts – on bridges over railway lines, for example.The wind forces which are likely to occur (impact pressure), or other extra loads, may make it neces-sary to use the Support beam T.These must be dimensioned on a project-specific basis.

Abutments

Variant 1

Bridge edge beam clamp located directly on

Bridge edge beam bracket

For smaller cantilevering projections b of up to approx. 48 cm.For this, the integral slide of the Bridge edge beam bracket must be dismantled first.To facilitate plumbing and striking of the formwork, the beams of the bottom formwork are rested on hardwood wedges (lift-out distance of bracket).

c ... 16.0 cmb ... Cantilever 0 - 48.0 cm (applies only where the side-formwork beams are in the positions shown)

For information on how to calculate the permissi-ble centre-to-centre distances of the anchorages, see the section headed "Extended system" in the type test for "Bridge edge beam formwork T".

User information Doka bridge edge beam formwork T Component overview



Fast, efficient manual forming of bridge edge kerbsBridge edge beam formwork T is ideal for shorter, completely scaffolded bridge superstructures, or for

bridges of medium length. It can also be used for fast, economical forming of curved bridges with tight radii. The low weight and high load-bearing capacity of the component parts – which are few in number – make this

system particularly suitable for manhandled forming applications.Doka bridge edge beam formwork T is available for rental, leasing or purchase.
