Prefabricated Panels
INDEX
Precast concrete panels have been extensively
used in the past. Currently, these panels can
be used and have been employed in the
construction of a variety of structures such as
offices, warehouses, apartments, recreation
centers, markets, churches and all types of
industrial and commercial buildings.
The panels can be manufactured in many
different shapes and sizes, although most
manufacturers have a standard panel.
All these panels are usually designed to meet
the needs of a particular work and have
advantages over other materials of possible
use.
The panels offer greater thermal insulation
than traditional elements, resulting in lower
energy consumption for heating or cooling
of buildings. Something similar can be said
about fire safety and savings obtained
insurance in the event.
The use of pre cast panels offers other
advantages, which may include eliminating
the need for perimeter columns and
horizontal greater resistance to impacts
of horizontal loads, which are possible in
industrial establishments.
The pre-cast concrete panels are more
resistant to penetration of air and moisture,
allowing storage of the walls without danger
of deterioration, often used in car washes
where the panels are permanently wet with
no signs of deterioration.
The pre-cast concrete panels can be fabricated
and raised, to a height of 15 m, which is an
important factor in some buildings.
These pre-cast panels can be manufactured
with a very large variation in both surface
texture and color. The interior smoothness
are finished can, with minimal preparation,
paint or cover with paper or other coatings.
Structures using pre cast concrete panels can
be built in 75% of time spent on the case of
using conventional elements. With respect
to conventional concrete structures can
save time spent in preparing the forms and
concrete with the appropriate placement
and curing of the latter. Finally it should be
noted that these elements pre achieve high
quality molded to be prepared at a central
facility where they can easily be practiced all
the controls are deemed necessary

1.1. Generalities
The machine of this manual is called Tilt
Table. Used for the production of concrete
panels. Basically, it consists of a tubular
structure supported on legs of laminated
profiles. This structure is manufactured in
modules of 12, 12.5 and 13 meters long, with
a maximum spacing between supports of
6.25 m. Modules is achieved by joining the
table length required by the Customer.
On the tubular structure there goes a sheet
of 10mm, which later takes a treatment of
polished, and a few bands on both sides of
the table that they make the dovetailing one
in the plate of concrete. The band performed
the female in the concrete is fixed and the
male is performing the swing.
The table has a working width of 2.5 meters
(optionally can be fabricated from 3 m-3.5-
4m) and can manufacture plates 12, 14, 16
and 20 cm thick.
The tilting of the table is by telescopic
hydraulic cylinders attached to the support
legs.
The regulation plate thickness and the
opening of the band folding is done by the
same mode by double-acting hydraulic
cylinders.
The table is accompanied by a hydraulic
control unit and electrical panel from which
you perform all these maneuvers.
The set comes complete with a pneumatic
vibration facility consists of vibrating
independently driven VSP 6623 and collector
of 1 “to connect the compressor Customer
owns.

2. Procedure of manufacture
2.1. Release Agent application
Within the panel manufacturing process,
one of the most important operations is the
application of release agent.
The table surface must be clean of impurities,
water and concrete debris. We will use a
clean cloth, and give the entire surface of the
table.
The application of release agents (type
recommended “CHRYSO DEM e-10), is by air
pistol, ensuring that the spray pattern in the
discharge is as closed as possible, consistent
with the pressure, it is advisable to be media/
high.
Bathe all trying to cover the maximum surface
without causing an over layer.
This operation as mentioned above, is
essential for the subsequent stripping of the
manufacturing line, in this case panels. This
will achieve a good surface finish of the panel
and it will prevent us from sticking to the
table.

2.2. Placement of partitions
This phase will suppose that the panels go out to the measures reflected in the planes.
The dividers can be fixed to the table of two forms: by means of magnets incorporated in his interior (low
photos) that prevent the movement of these during the vibrated one; ó with cats for simple dividers.
(To see top photo).

2.3. Manufacture and placement of armors
The design of the armor and the types of materials used can be varied. However the armor used
conventionally in precast concrete panels (except express customer specifications) will be the
type B400S.
B400S type is ideal for corrugated steel arm, equipped with a high ductility, which allows the time
to cut and fold, these operations safer and more effective. A number of studies have shown that
there are no tears or cracks when the steel is subjected to bending roller / spindles, etc
The armor is composed of: 150x150x6 mm
mesh. the entire surface of the plate. H170
perimeter lattice welded wire mesh on. Pin
extraction (2.5 TN. OR 5 TN. As plate) welded
to a corrugated bar ø16 mm., Which in turn is
welded to provide total body mesh.

The concrete we will do this with gentleness and Cuba
shaking or pouring spout so that the distribution is uniform
across the table.
Pour the concrete should be avoided with great force, since
it could sweep the release agent and we stick to the plate.
Vat for release
of concrete
The ideal procedure
would be poured,
carefully, a soft layer of
about 2 or 3 cm. around
the table, the rest of the
thickness can be filled
faster then exposed
concrete that sits on the
plate is the most sensitive
in the filling process.

The concrete used for this process is usually the type HA30 or HA35.
This type of quick-setting concrete is justified by the need for daily stripping of the panels, due to
high demand that exists today of these prefabricated components.
The quality finish is guaranteed.
2.2. Placement of partitions
With posteriority to the spillage of the concrete one will proceed to the levelled one and vibrated
of the same one. The level is achieved with the “rules vibrant” (see photo). With this transaction
we get the intended surface finish on one side of the panel.
Terminal and level
2.6. Shake and removal of panels
The release and removal process is quite
simple.
Just bring down the upper band and remove
the panels by bolts which, as previously
explained in paragraph 4 of armor, we have
placed.
For this operation one advises to use a
balance beam (to see photo) instead of
hooking them with the cables or chains of
the bridge crane directly, avoiding disorders
and losses of time. Then we will roll slightly
forward, so get it off the plate and also put it
in the vertical position we want.
Once this process gently remove the panel
up, and take you to the bridge crane to the
storage place. (See diagram pg. below).
NOTE: It is suitable to leave the panel setting
as minimum one week, to proceed to the
assembly.
