LITEFORM and the new reinforcement system for
traditional slabs and slabs cast in place present the
advantages of improving efficiency, reducing the
assembly time and increasing safety on site.

LITEFORM
Formworks for slabs
It is a security lightweight formwork for traditional and cast in site slabs, it has been
designed with the purpose to increase safety on site, improve productivity and reduce slab
implementation times. The system is especially suited for residential construction with rafter
and hollow block slabs but it is also suitable for monolithic concrete slab.
Safe (it is assembled from below), handy and easy to be assembled (aluminium panels are very
light), modular and highly productive, LITEFORM is the reinforcement system for slabs ideal for
small and medium-companies for any type of slabs.

Weight of LITEFORM falling head 5.3 kg.
It is suitable for monolithic slabs up to 26 cm thick (without lightening)
and conventional brick slabs.The expected loads can change from 4.5
to 7.0 KN/m2 with values for single prop from 9 to 15 kN. It included the
use of Class B or Class D props (according to EN 1065).
It can be used with any type of Liteform shore head. A special latch
prevents accidental release of the head from the shore.

ASSEMBLY
Before installation, the props must be reinforced with the related dismantling heads or fixed head.
It is sufficient to insert the head into the props the hooking device, prevents the accidental ejection and rotation of the head. Reinforce the
props with the related dismantling or fixed heads and place a first row of props by using the tripods (Fig. 1). Position the frames on the heads (it is
)2!"$*#$ '#$"#&"(*#(L?*")&"! ##0$1 #,))"$)* *#$>,*#2*()0#!!"$* ) &&$1#2*#*""(#%*"&(#&K1=<L=
The positioning of the frames on the heads can be carried out through a rotation of the frame by using the forklift. This operation completes
the reinforcement of the slab (Fig. 3). To reinforce brick or prefabricated slabs, the installation of all components is performed safely directly
on LITEFORM frames, the casting completes the work stage (Fig. 4). For the reinforcement of monolithic slabs, it is necessary to use a counter
casting surface in plywood or other panels placed directly on LITEFORM frames; then proceed with the reinforcement and casting.
Thanks to a device equipped on the dismantling head, it is possible to perform dismantling just a few days after casting (Fig. 5). Once the drop
heads have been lowered, all frames are recovered to reuse them in the subsequent stages and a new cycle of production can start (Fig. 6).
