developed a re

ormwork element

tto implem

reinforccement arm
mours in rreinforced concrete cconstruction
n elementss. This invvention is
characcterized thrrough its perfect ad
daptation tto any co
onstruction element currently
availab
ble in the m
market, resisting the p
pressure exerted thro
ough the co
oncrete. It is also a
low cosst element, quick and
d simple to use it, and
d it allows tto obtain clean and g
geometric
concre

MAIN ADVANT
TAGES OF
O THE T
TECHNO
OLOGY
The ad
dvantages o
of this elem
ment over ccurrently exxisting devvices on the
e market are:

It is reusab
ble, so tota
al cost of th
he work pro
oduct is red
duced.

The materrial used iin its manufacture iss resistantt to the thrusts derivved from
concreting
g.

The size and
a
weigh
ht of the element is reduced, sso it can b
be used th
hrough a
single operator.

It is not ne
ecessary an
ny addition
nal equipme
ent (craness) for handling.

The imple
ementation
n is quickk and sim
mple, reduccing execcution time
e of the
formwork.

Low cost o
of labour du
uring use.

It is possible to ma
anufacture different sizes and
d shapes, so it has a great
versatility to
t be used in any typ
pe of work a
and in any linear or surface
s
con
nstructive
element off reinforced
d concrete (e.g. slabss, tiles, bea
ams, walls, etc.).

It is easy tto be produ
uced, since
e it is a small element of simple
e geometryy that can
be manufa
actured thro
ough comp
panies from
m different sectors.

It has a lo
ow acquisition cost, ssince it is a piece of simple geo
ometry tha
at can be
manufactu
ured with diifferent ma
aterials.

Transporta
ation from the place of manufaccture is sim
mple, as it is a piece
e of small
size and w
weight that can be sta
acked or rolled.

It allows tto obtain cclean, geo
ometric an
nd easily-continued joints in re
einforced
concrete.

It can be re
emoved wiithout caussing damag
ge or abnormal jerking in concre
ete.
