2 CHARACTERISTICS
The vibrating screeds are used for the vibrating and the finishing of the floors in the construction industry
and for the finishing of parts in the pre-cas industry. The double beam screed depth-effect is from 15 to 25
cm. For very thick concrete layers, we recommend to use pokers at the same time in order to obtain the
right compaction and consistence of the concrete mass as well as its finishing.
The vibrations come from the vibrating group that consists on an exciter powered by a petrol engine or an
electric motor.
Double beam screed consists on a set of aluminium or steel beams (sold separately) able to extend from
2,7 or 3,5 meters to 4,5 or 6 meters length. To increase the length it is necessary to free the vibrating group
clamps and to pull the beams to get the required length. Then, fix the vibrating group clamps again.
The vibrating group fit in the beams and is fixed to them with two clamps (one on each side).
It is possible to choose a vibrating group powered by an electric vibrator or a petrol engine. In the case of
the petrol engine, vibration is produced by an eccentric weight, assembled with bearings, inside a steel
housing. This housing also works as an oil tank for lubricating the bearings. A belt transmits the movement
from the engine (assembled on four silent-blocks to isolate it from vibrations) to the pulley of the eccentric
weight to produce the vibration.
There is a hook on each edge of the beam where the pulling handle must be inserted for pulling the screed
while working.
***S/L=no time limitation, taking as a reference a working period of 8 hours a day.

convenient socket must be used.
Do not use damaged cables.
Avoid heavy loads on cables
To determine the transversal section, follow the following procedure:
Procedure to determine the necessary transversal section in cable extensions:
Do the following verifications and take the highest section of cable:
1.- The ohmic resistance and inductive resistance of the cable with the permitted loss of voltage of
2%,
cos
= 0.8 through the frequency and voltage curve.
I.e.: Nominal voltage:………………… 1- 230 V 50 Hz
Nominal current:…………………...10 A
Cable length:……………………….100 m
Entering the curve with the product: Intensity x Length = 10 x 100 = 1000 A m.
We obtain a 4 mm2section.

8 RECOMENDATIONS OF USE
The screeds are used to the vibration and the finishing of the floors. You can work directly on the
surface with guides. Before starting the guides must be adapted. Then the steel structure is posed
on the concrete mass. The screed is laid over the guides and the work can start. (two operators are
demanded). Thanks to its weight and to its mechanism producing a powerful vibration, the screed is
ideal to smooth rapidly and easilythe floors (more than 15 cm).
For the floors which measure more than 30 cm the concrete mass is also vibrated with vibrating
equipment before the finishing with the screed.
In order to get a good finishing of the concrete surface, we recommend you to follow these
instructions:
1.- Before pouring the concrete mass on the structure, it is necessary to properly level the concrete
mass. To an easier compaction of the concrete, you should use the vibrating pokers additionally. It's
important to take references or levels out of the mass to see the level objective clearly. The markings
of the feet and tools disappears after the last pass of the screed. The vibration wave produced
reaches a depth until 18 cm depending on the type of concrete mass.
2.- When the mass is prepared, the screed is laid over the concrete mass with the motor running at
the top speed and you must pull the handles slightly in order not to spring over the surface and not
create "waves" and "markings" with edges. Pull constantly the screed, it is important to get a smooth
surface. The screed must be always in contact with the concrete when working. The screed must not
show a big resistance to pulling, it must slip over the concrete. The speed to pull the screed depends
on the depth and the consistencyof the mass.
3.- To judge the quality of the vibration, the markings of the feet and of the beam must disappear. In
the case of the concrete is not really smooth repeat the previous instruction.
4.- Then, we see a mix that we call "milk" on the surface (3-4 mm water, concrete, small sand
particles).
5.- The water will evaporate quickly and the surface becomes dull. The fine layer called "milk" is
acting as a cinder paper for the under layers and avoids the sweating effect. The water stays in the
under layers and the surface moistens.
6.- Some hours later, the concrete is ready for additional finishing operations. You can use a trowel
(single or double ride-on-type) or re-vibration equipment (double roller unit with integrated vibrating
system). The machines provide a higher resistance to wearing but are not required for all the types
of floors.
