Elementary safety warnings
User target groups
• ●This User Information booklet (Method
Statement) is aimed at everyone who will be
working with the Gael Form product or system
it describes. It contains information on how to
set up this system, and on correct, compliant
utilization 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 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 Gael Form (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.
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/
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.
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.
• ●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
3
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.
Assembly
• ●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
Gael Form for advice first.
• The assembly work must be carried out by
suitably qualified employees of the client’s.
Erecting the formwork
• ●Gael Form 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.
• ●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!

Gael Flex H20 Loose Deck - the versatile hand-set system for floor-slabs
Gael Flex H20 Loose Deck can easily be adapted to
fit any lay- out, simply by telescoping the Gael Form
H20 beams. The materials planning work is done by
slide-rule, which appreciably reduces the costs of
planning and operations scheduling.
• ●no structural-design work is needed, as H20
Loose Deck shows you the maximum spacing for
all slabs up to 30 cm thick
• ●you can tell at a glance whether the formwork
has been set up correctly
Further advantages:
• ●infill zones are managed within the system,
making it easy to accommodate walls and
columns
• ●for shoring heights of up to 5.50 m
• ●any type of form-facing can be used
• ●no need to measure up
Gael Flex H20 Loose Deck is ideal for enclosed
spaces where the formwork superstructure can rest
up against walls on all sides.
Horizontal forces at exposed slab-edges, drop
beams or steps in ceiling slabs must be restrained
by strutting or back-stays
Small number of system components - all perfectly coordinated

• The marks on the beams show you the maximum spacing:
- every 4 marks for primary beams
- every 6 marks for props with removable folding tripods
The straightforward logic underlying the Gael Flex H20 Loose Deck system means that there is no need for
planning and operations scheduling work. The quantities are simply computed using the materials sliderule

Instructions for assembly and use
IMPORTANT NOTE: As well as the instructions given here, the section headed “Reshoring props, concrete technology and striking” MUST be followed.!
CAUTION! If the floor props are transported with the lowering heads still attached, you must secure these with a Spring-locked pin 16 mm to prevent them dropping out. This is particularly important when they are transported in the horizontal.
!
IMPORTANT NOTE: Do not oil or grease wedge-clamped joins.!
The lowering heads that will be un-der the primary beams next to the walls must be turned inwards so that they can be knocked undone when the time comes to take down the formwork.
Erecting the formworkPutting up the floor props
• ●Place primary and secondary beams along the
edges.
Max centre of secondary beams 500mm on
3000mm deep slab
- 4 for primary beams 2m centres on primary
beam on 3000mm deep slab
- 2nd 1m for props on 3000mm deep slab
• ●Roughly adjust the height of the floor prop, using
the fastening clamp.
• ●Put up each removable folding tripod.
• ●Put the floor prop into the tripod and fix it in place
with the clamping lever. Before stepping onto
the formwork, check again to make sure that the
props have been correctly fixed in the tripods.
Setting up tripods in corners or up against walls
If it is not possible to completely unfold the legs
of the tripod – e.g. at the edges of a structure or at
floor breakthroughs etc. we recommend fastening
this tripod to an adjacent floor prop instead,
where there is room for the legs to be completely
7
WARNING!It is not permitted to set down any loads on the floor-slab formwork (e.g. beams, panels, reinforcements) until the interme- diate props have been set up!
!
IMPORTANT NOTE: Wherever necessary, connect secondary and primary beams using the Connector clip H20.
!
Be sure to place a beam (or double beam) wherever there is to be a joint between the Gael Form ply panels.
!
Planks can be attached to the floor props as diagonal braces, using the Bracing clamp B. (This is only to help stand the props upright and is not suit-able for restraining horizontal loads).
Inserting the primary beams
• ●Using beam-forks, place the primary beams into
the lowering heads
• The lowering heads can hold both single beams
(on edge-of-room props) and double beams (at
overlaps).
• ●Adjust the primary beams to the correct floor-
slab height.
Placing the secondary beams on the primary beams
• ●Use the beam forks to place the secondary
beams on the primary beams, with an overlap.
• Maximum spacing of secondary beams 500mm
3000mm deep slab

A Supporting head H20 DF
B Gael Form beam H20 top
IMPORTANT NOTE: Put on personal protective equipment before starting to mount the guard rails.
!
Putting up the intermediate props
• Place the Supporting head H20 GF on the inside
tube of the floor prop and secure it with the
integral spring-steel stirrup
• Put up the intermediate props.
Maximum prop spacing: 2 marks apart
Laying the Gael Form 21mm 3-ply panels
• Mount guard rails around all exposed edges.
There are 4 possible ways of ensuring safety
when laying the Gael Form21mm 3-ply panels:
» A mobile fall barrier makes it possible to
lay the Gael Form 21mm 3-ply panels
safely when working from above.
9
IMPORTANT NOTE: Windproofing
●For increased stability, in larger rooms, the full erection sequence of “primary beams + secondary beams + formwork sheets” should be carried out progres-sively for successive sub-areas of the room. When doing this, provide suitable bracing to walls or columns.
●If there is any risk of the formwork being blown over, all free-standing, non-en-closed areas of slab formwork must be secured during work-breaks and when work finishes for the day.
!
Where necessary (e.g. edge zones), secure the form-ply with nails.Recommended nail lengths
• sheet thickness 21 mm- approx. 50 mm
• sheet thickness 27 mm- approx. 60 mm
The Wheel-around scaffold is ideal for striking the formwork from floor-slabs above rooms of medium height.
• collapsible wheelaround platformmade of light alloy
• variable working heights of up to3.80 m (max. platform height: 1.75 m)
• platform width: 0.80 m
For greater heights than this, the Gael Form mobile scaffold tower is ideal.
Observe all stipulated stripping times!!
• Lay the Gael Form panels at right angles to the
secondary beams.
• Spray the Gael Form 21mm 3-ply panels with
parting agent.
PouringTo protect the surface of the form-facing, we
recommend using a vibrator with a protective rubber
cap.
Striking
Removing the intermediate props
• Remove the intermediate props and put them in
the stacking pallet.
After the intermediate props have been removed,
there remain only props spaced 2.0 m apart in
the direction of the secondary beams and 3.0 m
apart in the direction of the primary beams. This
leaves enough space to manoeuvre wheel-around
scaffolds and stacking pallets without difficulty.
10
When lifting the equipment to the next storey, it is better to transport the floor props and the lowering heads separate-ly (the floor props on their own can be stored much more space efficiently in the stacking pallet)
IMPORTANT NOTE: For further information (number of props etc.), see “Reshoring props, concrete technology and striking”
!
Lowering the floor-slab formwork
• Lower the floor-slab formwork by striking the
wedge on the lowering head with a hammer
Removing parts that are no longer needed
• Turn the secondary beams over onto their sides,
pull them out and put them in the stacking pallet.
Leave the beams under the panel-joints in place.
• Take out the Gael Form 21mm 3-ply panels and
put them in the stacking pallet.
• Remove the remaining secondary beams and the
primary beams, and put them in the stacking pallet.
Removing the floor props
1) Hold the inner tube with one hand.
2) Open the fastening clamp to unfix the inner tube.
Guide this by hand while lowering it into the outer
tube
Put the removable folding tripods and props in the
stacking pallet.
Repropping
• Before pouring the next floor-slab (i.e. above the
one that has just been stripped), put up reshoring
props.

System components of Gael Flex H20 Loose Deck – also for slab thicknesses of over 30 cm
Only one system in use on the site
Up to a slab thickness of 30 cm, no structural design work is needed. However, it is also possible to compute
the exact quantities of the same system components that will be needed for any given thickness of slab,
with reference to the table. In this way, only as much formwork equipment is used as is really needed, as
dictated by the slab load. The following tables assume a live load of 20 percent of the dead load of the fresh
concrete, but not less than 1.5 kN/m² (150 kg/m²). Mid-span deflection has been limited to l/500. On the
site, the easy-to-use slide-rule is ideal for determining the permissible spacing of primary beams and props.
