Applications
Fast-EZ High-Ribbed Formwork,
consisting of steel sheets formed
into mesh and U pattern rib bone,
will produce a surface with
concrete which will bond directly
to the next pour without any
special treatment.
The formwork is widely used
in building construction to form
retaining walls, columns,
stopends, construction joints and
used to support slab flooring.
Quality Approval
British CP114 armoured concrete
structure standards 1969
British 399 Chapter 1 standards
on application of constant load
and exerted load 1984 (CP3T Book
5 Chapter 1)
Materials
Fast-EZ High-Ribbed Formwork is
manufactured from hot-dip zinc
coated steel sheet to BS 2989 Z2
G275 standards.
Manufacture
The mesh and ribs are formed
on machines which first cut and
press the mesh and then roll-form
the ribs. At the same time the
material is stretched to form an
expanded mesh.
Model: HR26G
Thickness: 0.35MM
Weight: 3.4KG/Sqm
Size: 450MMx2500MM
Features & Advantages
Structure & Mechanism
Fast-EZ High-Ribbed Formwork
will wedge its projections on the
mesh into the concrete when it is
poured in, and mechanical wedges
thus are formed to bond adjacent
cement blocks. The jointing
quality is subject to strict
control and the bonding and
shearing strength are capable of
matching to that of specially
treated bonds.
1.Good mechanical performance and
low side pressure
Fast-EZ High-Ribbed Formwork
is only subject to 60% of side
pressure compared with common
formwork, thus enabling to
decrease weight of rib bone by
40%.
2.Visual concrete pouring
Because it is comprised of
porous open mesh, Fast-EZ High-
Ribbed Formwork reduces the risk
of voids and/or honeycombing
occurring within the concrete.
3.Lightweight and convenience for
transportation and installation
Fast-EZ High-Ribbed Formwork is
only 10% as heavy as the common
steel module, featuring fast
installation and convenient
transportation.
4.Optimizing technologies and
increasing shearing strength
Fast-EZ High Ribbed Formwork
will produce an ideal surface
with high shearing strength
combined with poured mortar that
will penetrate into the formwork
through the mesh pores.
5.Convenience for reinforced
steel bar to go through and tie
continuously
Fast-EZ High-Ribbed Formwork
is of multiple pores and special
mesh. It is easy to let
reinforced steel bar 12mm below
to go through the formwork just
with little force. For reinforced
steel bar with large diameter, it
can go through by shearing the
mesh. Besides, the formwork can
be installed before tying the
bars that can then penetrate into
the form through the mesh.
6.Suitable for segmented concrete
pouring
Fast-EZ High-Ribbed Formwork
is a permanent one that is easy
for concrete to bond with the
next pour without dismantling the
formwork or making a juncture,
thus simplifying bonding work.
7. Easy for muff coupling and
shearing
Fast-EZ High-Ribbed Formwork
is multifunctional, easy to cut
and bendable to form different
shape to meet different
requirements.
Installation
Fast-EZ High-Ribbed Formwork can
be used combined with traditional
frame.
It is equivalent to 20mm plywood.
It can be installed with the ribs
placed horizontally or
vertically, but support members
should always be at right angles
to the ribs.
Ribs should be always face the
side towards which concrete is
poured in.
Mesh is suitable to be cut with
heavy scissor or grinder on the
site.
Adjacent sheets should jointed by
overlapping the ribs by 150mm.
End sheets are overlapped by
150mm over the supports.
Fast-EZ High-Ribbed Formwork
can be used with all conventional
support systems. To eliminate
stripping of support, suitably
formed rebar can be sued instead
of conventional timber studs.
Fastening to supports can be by
nailing to timber or by wire
tying to steel and rebar.
Adjacent sheets of high-ribbed
formwork are joined by
overlapping the ribs and tying
the outer ribs at 150mm
intervals. The rim of sheets
should be overstepped by 150mm
over the support.
Fast-EZ High-Ribbed Formwork
can be installed with the ribs
placed horizontally or vertically
to meet different requirements.
Support members should always be
at right angles to the ribs to
withstand the formwork.
On-Site Operation
Fast-EZ High-Ribbed Formwork is
suitable for use with most grades
of concrete including concrete
pumping and plastic concrete.
The slump should be between 70mm
and 100mm although slumps up to
125mm can be used. In this
situation the use of concrete
vibrators in proximity to the
high-ribbed formwork has to be
limited in order to minimize
grout loss.
It is most suitable to pour the
concrete much behind the
formwork. In this way, it can not
only decrease shock load and
enable the concrete to be poured
in the appropriate position but
also produce high bonding
quality.
The formwork will be embedded in
the concrete. To obtain suitable
wedge surface, the formwork
surface should be corrugated.
Allow concrete to exude from the
mesh of the formwork until a
corrugated surface is formed.
Application of vibrators can help
speed up the flow of concrete up
to the formwork. The vibrators
should be at least 450mm away
form the formwork, especially
used for damped concrete.
Excessive vibration should be
avoided near the bonding of the
concrete so as to ensure no voids
and/or honeycomb occurring in the
concrete. Meanwhile, it is also
unallowable to let concrete flow
down along the form surface.
The water gathered on the surface
during vibration should be
quickly removed away, because it
is easy to flush the ripple when
flowing down.
Generally, when it is hard to
form the surface required, it is
not because that the concrete is
too wet but that it is too dry.
So the possible reason is that
you have not complied with the
standard to mix the concrete.
Due to continual product
improvement, specifications are
subject to change without prior
notice.
