CLASSIFICATION OF THE PIL PRODUCTS



2.1 FUNDAMENTALS OF THE PIL SYSTEM

The PIL construction system is based on a series of

polystyrene panels and galvanized steel wire

meshes. The shape has been especially designed

for the introduction of traditional or structural plaster

during on-site panel installations.

PIL provides a system of industrialized modular

panels allowing for faster assembly than

conventional systems. The PIL system fulfils the

required structural and load-bearing functions,

offering high thermal and sound resistance and a

wide range of shapes and finishes to provide

versatility in the design compaction process.

2.2 COMPOSITION OF THE PIL PANELS

The following are the basic components:

a) A foam polystyrene core which is non-toxic, non-

hazardous, self-extinguishing and chemically inert

with varying density and thickness depending on

panel type.

b) Electro-welded steel wire meshes made

of galvanized drawn steel wires placed

on both sides of the polystyrene panel

and connected by means of joints of the

same material. The wire gauge steel net

varies according to panel type and mesh

direction.

2.3 PLASTERING

After the panel assembly, structural

plaster should be sprayed and/or poured

on the panel-depending on panel type.

2. DESCRIPTION OF THE PIL SYSTEM



A. Versatility & diversity of panels to accommodate

different architecture and design features.

B. Thermal properties and sound resistance

C. Easy to move, rapid assembly with little or no need

for lifting equipment and high durability

D. Structural capacity and resistance to earthquakes

and hurricanes

E. No skilled labour is required

F. Less construction time

G. Lower foundations costs compared with traditional

systems

H. Full utilization within the same building system

I. PIL system easily integrates with traditional

systems

J. Highly fire-proof material

K. Easy and rapid installation of plumbing,

heating, electric, telephone system etc.

L. Panels can be fabricated to customised

lengths and thickness.

N. Panel surface and PIL plastering machines are

especially designed for a smooth plaster

spraying

O. PIL panel meshes also include connection

flanges

P. The polystyrene core can avoid the thermal

bridge

Q. PIL panels density does not change following

exposure to weather conditions over time.

The double panel PSM consists of

two single panels facing each other

and joined by steel pins keeping

them at the distance established by

the static requirement to be met.

The space between them is filled

with cast concrete having suitable

resistance strength.

Externally, the panels must be

sprayed on with plaster as the

single panels.

Although no additional

reinforcement is necessary for

buildings up to three storey’s, for

taller buildings the panel should be

further reinforced with internal

additional meshwork.

Soundproofing index: I > 38 dB at 500 Hz (in frequency band between

100 and 3150 Hz)

This type of panel enables the use of

the PIL system for floors and roofs

by inserting reinforced ribs in the

special spaces and subsequent

concrete casting on site. In fact the

reinforcement of the panel is

integrated during the panel

assembly by the insertion of

additional reinforcement bars-to be

substantiated by calculations –

inside the panel ribs.

It is an ideal solution for floor slabs

having spans up to 6.5m. and the

double rib for spans of up to 10m

overloading up to 400 daN/m2.

furthermore, where the assembly

sequence needs to be maximised,

as far as the erection schedule is

concerned, it is possible to use iron

stiffening rib in the pods of the panel.

Fire resistance REI 120*:

The panel consists of an expanded

polystyrene block shaped according to

designing requirements and reinforced by a

steel mesh. The block is joined by steel wire

connectors welded in electro-fusion across

the polystyrene core.

Suitable reinforced and finished with casting

on site in the suitable spaces, it is used for

the construction of flight of stairs up to a

maximum spans of 20 ft having a live load

of 82 lb/ft2 (400 Kgm2)

The reinforcement steel bars have to be

placed inside the holes.

4.6 TECHNICAL SPECIFICATIONS AND USE OF STAIRCASE PANEL

This panel is used for the construction of

flight of stairs of up to 6m long (floor at

approx. 3-m intervals) having an accidental

overload of 400 kg/m².

During construction and prior to panel

assembly, the stair panel, lower channels

are filled with concrete (the panel being

placed upside down). This pre-cast operation

confers greater stiffness to the panel during

its assembly enabling at the same time a

drastic reduction of the number of props

used.

Once the stair panel is assembled and the

lattice is placed inside the panel internal

channels, the latter are completed with

gravel concrete (whose particles size is < 12

mm and its minimum strength is Rck > 250

dN/cm²

The concrete may be cast in the panel ribs

contemporaneously with casting of the upper

coating. In case this already exists, the

concrete may be applied to both the ribs and

upper joist.

Successively, the plaster layers (2.5cm thick)

are applied upon the flight of the stairs, first

the lower side and then the upper one, in

order to form the basis on which the flooring

(marble, ceramic tiles, etc) is to be laid.

User’s Instructions

• The air pressure should be kept constant within a

70-120 pound _500-800kPa range.

• No special plastering-machines are needed and the

panel to be plastered required no previous

preparation.

• For the plaster to be applied to the wall, the container

should be placed at a distance of 10-20cm.

• For the plaster to be applied to the ceiling, the upper

edge of the container should almost touch the panel

at a maximum distance of 2-3cm.

Plaster sprayers maintenance

• During the usual interval between the application of

two layers of plaster, we recommend you place the

empty container in a bucket filled with water and

make it work two or three times.

• Remove lateral bolts and wash the inside of the

machine at least once a week.

Compressors:

Either electrical or internal-combustion engine

compressors may be used keeping in mind the

following data.


Note 2:

When only one plastering-

machine is used, the ideal

cubic capacity of the

compressor container is

220 litres (not lower than

130 litres, but with pressure

regulator).

6. PIL PLASTER SPRAYERS FOR WALL

AND CEILINGS

The use of the devices easily enables time saving by

50% and with no need for skilled labour. With PIL

sprayers, the plaster may be applied with a degree of

adherence that could not be achieved manually, in one

hour, one worker using a plaster sprayer with a

continuous flow of material placed nearby can apply a

plaster layer of about 1cm over an area of up to 646 ft2

(60 m2). PIL plaster sprayers are available in two

versions.

W for walls and C for ceilings. Both models feature four

holes for different types of plaster and come with all the

necessary tools to clean the machine after use.

Note 1:

We recommend the use

the use of high pressure

½” hoses note exceeding

30 linear meters.

CONSTRUCTION TECHNIQUE

1. FOUNDATION

Typical foundation incorporating DPCs should be

used. Starter bars either from foundation or ground

floor slab.

3. BRACING AND MESHWORK INSTALLATION

All Internal walls are reinforced with angular mesh whichgives the structural mesh greater continuity. By reinforcingcorners where two walls join. This mesh is applied to theinside and outside of the wall and every intersection.

Door & Window Openings are braced using flat mesh at 45°above (this acts as the lintel therefore no lintel is needed)and below corners of the opening. “U” shaped meshreinforces the top of every panel, door frames and windowsills to provide extra-strong threshold to anchor frames.


2. ASSEMBLY OF WALL PANELS

PIL Panels are anchored to the foundation or floor slab

at ground level with starter bars. In order to guarantee

the continuity among the elements, the PIL panels are

equipped on both sides with mesh overlap from panel

to panel and binding wire is used to secure the mesh

panels.


4. SERVICES

The layering of pipes for plumbing, electrical

installation...etc takes place after the polystyrene panels

have been erected and before the spraying of concrete

take place.

The polystyrene is melted using a hot air gun or similar

tool. The electrical flexible pipes are placed under the

meshwork.

The area surrounding the cut should be restored by the

addition of extra mesh connected to the meshwork of

the panel.


5. SPRAYED CONCRETE

An approved concrete mix of 25Mpa is sprayed

on the panels using a plaster sprayer/spray gun.
