Description
A ROOFING PRODUCT
This invention relates to a roofing product, and in particular insulative roofing products.
The following insulative roofing products are
known:
(1) Asbestos type tiles:
Most developed countries have legislated against
the use of asbestos because of its harmful effect
to human health.
(2) Hollow type tiles:- As there is, no air "convention effect" in the
hollow part of the tile, heat will accumulate and
cannot be dissipated. Roof-tops laid with a
layer of such tiles cannot b used to walk on by
people, and oozing will easily occur.
(3) Concrete foam tiles By using the process of shotcrete grouting, the
whole roof-top is laid with a layer of 8-lO cm of
concrete foam. The thermal insulation effect is
better than that of hollow type tiles. However.,
this method is difficult to handle and in
particular to lay. Its biggest dcfect is that
the glal.ity of concrete foam is very fragile and
may disintegrate under slight pressure. The
material is also subject to weathering as time
passes and is bygroscopic so as to cause oozing.
Roof-tops laid with such tiles cannot be used to
walk on by people.
( Hard PU (High Density Polyurethane) type roofing: - As PU plastic material has a heat insulating
effect, this current heat insulative products may
he laid on top of another material or laid on the
roof and covered on top with other material, or
sandwiched in the middle with PU in a rigid form
(the so called "sandwich type"). There are
numerous varieties, however, they all share the
same defects as those of concrete foam in that
they are fragile, will absorb water and weather
with time, leading to oozing. At the same time,
its price is more expensive and its volume more
bulky, and the roof-top is unusable for walking
on by people after installation.
(5) Pleat screening paste type roofing:- This type is a kind of chemical coating material
applied by spraying the material on to the
surface of the roof-top. It will be effective
initially but will lose the effect of reflecting
heat when dust accumulates on its surface as time
passes. Another problem is that with such
application the roof-top cannot be used for
walking on by people. It is also expensive.
(6) Fibre-Glass type roof ing:- This type of roofing is extremely expensive. Its
defects are the same as those of the previous two
types.
It is an object of the invention to provide an insulative roofing product having improved characteristics over known roofing products.
In accordance with the invention, a roofing product is provided in which the interior thereof is substantially of polystyrene insulating material.
Such is light, strong, and easy to apply, yet superior in thermal screening and water-proof ing. It will increase the usability of and decrease problems associated with roof-tops of buildings, since it will be possible for the occupier of the top-floor of a building to eliminate the twin problems of "heat" and "oozing" without reducing the usable areas of roof-tops, thus improving living conditions.
Such a roofing product has a very good thermal insulating effect. The polystyrene insulating material is relatively light and reluctant in combining with other materials, and has a flexible load strength sufficient to allow people to walk on the roofing product. The roofing product is not only thermally insulative, but also water-proof.
Suitably, the insulating material is expanded polystyrene (also known as Soly Foam Styropor).
Advantageously, the roofing product includes an internal mass of insulative material surrounded by a crust of concrete material. Preferably, the mass of insulative material is provided with a plura y of grooves in the upper and lower layers thereof, the plurality of grooves on the upper surface being offset from the plurality of grooves provided on the lower surface. The concrete during moulding fills these various grooves provided on the upper and lower surf aces, in order to strengthen the resultant outer crust of concrete.
Suitahly, the mass of insulative material has a plurality of holes passing completely therethrough from the upper to the lower surfaces thereof, and in particular the plurality of holes are situated within the grooves provided on the upper surface of the mass of insulative material.
Similarly, the concrete during moulding fills these holes, in order to provide a solid connection between the upper and lower surfaces of the resultant concrete crust, thereby strengthen the whole arrangement.
Suitably, the mass of insulative material occupies at least 80% (and more preferably at least 90%, and most preferably at least 95tut) of the plan cross-sectional area of the roofing product.
The invention will now be described by way of reference to the accompanying drawings, in which: Fibre 1. is a perspective view of a roofing
product in accordance with the invention;
Figure 2 is a perspective view of an internal
component of the roofing product of Figure 1;
Figure 3 is a side cross-sectional view of
product of Figure 1;
Figure 4 is an underneath cross-sectional view of
the product of Figure 1;
Figure 5 is a plan cross-sectional view of the
product of Figure 1;
Figure 6 is a cross-sectional side view of a roof
with roofing products as shown in Figure 1; and
Figures 7A to E show the manufacturing steps of a
roofing product as shown in Figure 1.
The roofing product shown in Figure 1 is in the form of a tile or brick 10 which comprises an outer shell of concrete 12 provided around an internal component 14, details of which are shown in Figures 2 to 5.
The internal component 14 shown in Figure 2 comprises a slab of expanded Polystyrene (EPS - also known as Poly Foam Styropor) with a series of criss-cross channels 16 on the upper and lower surf aces thereof, together with four holes 18 provided in the upper series of criss-cross channels, which holes 18 pass completely through to the bottom of the component. The channels 16 on the upper surface are offset from the channels 16 on the lower surface.The channels 16 and holes 18 are provided in order to strength the outer shell of concrete, since connecting plugs of concrete between the upper and lower layers of concrete are formed in the holes lS, and the upper and lower layers of concrete are rigidly secured to the upper and lower layers of the internal component respectively due to concrete filling the channels 16.
In Figure 6, an arrangement. showing use of the roofing product is shown, and in particular two roofing products 10 are shown side by side on a roof 20, the two products 10 being connected together (and to the side wall of the roof 20) by an appropriate adhesive mixture 22 (such as a water-proof cement or an elastic and long-lived silicone glue).
The roofing product of Figure 1 is manufactured using the internal component shown in Figure 2 by the manufacturing steps shown in Figures 7A to E In particular, a mould box 30 having a base 31 and sides 33 as shown in Figure 7A is used upon which a lower layer 32 of concrete is formed (see Figure 7B), whereafter the internal component 14 of Figure 2 is placed within the mould box and pressed onto the layer 32 of concrete such that concrete fills the channels 16 on the bottom of the internal component (see Figure 7C), and finally a final layer 34 of concrete is placed in the mould box 30 on top of the internal component 14, which concrete also firstly moves around the sides of the internal component to form the sides 35 of the roofing product, secondly fills up the holes 18 thereof, and thereby provides connecting plugs between the upper and lower concrete layers 32 and 34 of the roofing product 10, and thirdly fills the channels 16 on the top of the internal component. The sides 33 of the mould box 30 are then removed to reveal the formed roofing product 10 which is then ready for removal (see Figure 7E) from the base 31.
The invention will now be described in greater detail, and in particular the deign, function and manufacturing aspects of the invention will be described.
Design of the roofing product is as follows: (I) Size:- Length : 300 mm
Width : 300 mm
Thickness: 38 mm
(or other sizes) according to need.
(2) Material:- cement, sand and EPS internal component of
specified size.
(3) The thickness of the six outer surfaces of the
roofing product crust (1 top, 1 bottom and 4
lateral sides) is 5 mm; the whole interior is
filled with the high dens.ity EPS internal
component, (4) The EPS internal component is moulded to the
specified measurement and shape, and then formed
into the interior of the roofing product.
(5) To increase the srenth of the outer surfaces. of
the roofing product (i.e. the crust), a criss-cross rectangular internal component is
used having grooves lG concaved inwards on the
top and bottom layers, which causes during
moulding the internal top and bottom surfaces of
the crust to be formed with ribs thereby
providing an arrangement equivalent to a "Grillage beam", in other words distributing the
pressure on the roofing product surface evenly
from 300 mm down to 75 rnm.
Also there are at least four holes 18 piercing
through the EPS internal components from the top
to bottom layer which form connecting plugs when
the mould box is filled. The "Grillage beam" and
plugs crust arrangement needs to be reverse
designed to make it fit into the concaves of the
EPS internal component, and in this regard the
EPS internal component will become the "base
mould". When the mould box is filled up with
cement paste, the inner shape of the crust may be
set in a single step.
Function of the roofing product is as follows: (1) Although the apparent conductive area of the
roofing product is 300 mm x 300 mm, heat can
practically only he conducted to the bottom part
(that is the floor of the roof-top) from the four
sides of the crust of the roofing product (5 mm
in width), and the four connecting plugs of 8 mm
in diameter each. That is to say the effective
conductive area of the roofing product is only 1/28 of the total roofing product area. The rest
of the heat, being unable to permeate through the
interior of the EPS "screening layer", can only
stay at the surface of the roofing product,
exerting no influence at the bottom (in other
words the original top layer of the roof-top).
(2) For the same reason, the heat absorbed by the
surface of the roofing product 10 can, since it
is in contact with moving air, be quickly
dissipated, whereas other known heat insulating
materials require a much longer time to dissipate
the heat accumulated at their interior.
(3) As the body (material) of the roofing product is
largely made up of EPS of very light specific
gravity, its weight is only about 2/5th of
roofing products of the same size. Therefore,
cost for materials, transportation and
application is greatly reduced.
(4) As the mould for producing the roofing product is
specifically designed, the surf ace of the roofing product is smooth and good-looking (and in fact
could also be provided with an ornamental surface
design), and can carry a load of 220 kilogram without danger of disintegration. This is
unrivaled by other insulating roofing materials.
(5) Since, apart from the four sides and the four
connecting plugs, 27/28 of the roofing product
body is absolutely water-proof EPS, one need only
fill up the gaps between adjacent roofing
products with water-proof cement (or elastic and
long-lived silicone glue) during the process of
application of the roofing products to a roof to
ac.hieve an ooze-proof roof-top.
Manufacturing of the roofing product is as follows:- (S) Production eguipment:- (a) raw material mixer.
(b) mould: made of aluminium alloy, and each
mould set for the roofing product, including
one bottom board, four templets, and four
fixing locks.
(2) Basic materials:
(a) hydrophobic cement
(b) fine sand (C) EPS internal component (3) Manufacturing steps:
(a) fix the four templets onto the bottom board
with the fixing locks (see Figure 7h).
(b) apply a layer of S mm thick mixed cement
paste inside the mould (see Figure 7B).
(c) place the pre-made EPS internal component
inside the middle of the mould with a gap df 5 mm from each of the four sides of the
mould (see Figure 7C).
(d) fill up the space between the four side
frames and the EPS internal component until tho BPG internal component is covered up; then top up to the surface of the mould (see
Figure 7D).
(e) apply a little vibration.
(f) smooth out the cement paste at the top of
the mould.
(g) dry it naturally until solidification.
(h) after a lapse of about 24 hours the cement
solidifies, the roof product is then pulled
out from the mould and the process is
completed (see Figure 7E).
For mass production, the mould should be modified to a standing type so as to produce 6 to 8 pieces at a time.
Comparison tests between the roofing product of the present invention and known roofing products have been conducted, and the results thereof will be ascertained from the following table:

Roofing prodct' of present MOoQoo M e 0 0 0 0 # EXCELLENT # GOOD # FAIR XNO GOOD X H M MEDIAN L LOW A thermal insulation test was also conducted on a roofing product in accordance with the present invention, namely heat was applied on one surface for six hours at 360C, whereafter the temperature of the other side was measured and found to be 30.50C (room temperature was 29.50C), The roofing product of the invention has superior heat insulation properties due to the interior construction of the product.In particular, a quasi vacuum thermal insulation layer reduces the superficial area of thermal conduction to 1/28, thus obtaining ideal thermal insulation,
In particular, the internally ribbed crust of the roofing product together with the internal connecting plugs act like grillage beams of a building structure, and in conseTuence the flextural load of the roofing product is greatly enhanced without having the fragility normally found in ordinary roof-top insulation materials.
The roofing product is extremely water-proof, due to the fact that the internal construction, which is formed of expanded polystyrene is 100% water-proof. The materials of the roofing product are simple, namely cement, sand and expanded polystyrene, and therefore the roofing product is simple and relatively cheap to manufacture. Furthermore, its weight is light, and in particular is about 2/5th of that of a cement roofing product of the same volume.
