Description
TECHNICAL FIELD OF THE INVENTION
[0001] The present invention relates to a roof design that
comprises an external sheet covering, an insulating layer provided
beneath the sheet covering and a load carrying structure that
supports the insulating layer.
PRIOR ART
[0002] From DE 198 16 980 A1 a building component is previously
known, said building component being manufactured by having a
floating moulding material pumped into a space between a permanent
mould constituting two sheet metals and an opposite mould. When the
moulding material has hardened a building component is achieved
where the external layer in the permanent mould constitute the
external roof covering. A pipe system is also included in the
building component, said system being arranged between the two
sheet metals in the permanent mould. In the pipe system liquid is
circulated, said liquid collecting solar energy.

roof design where the external sheet covering is given a sufficient
underlying support.
[0004] Still an object of the present invention is that the
underlying support of the sheet covering has a heat insulating
function.
[0005] A further object of the present invention is to avoid

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
[0019] The embodiment, shown in FIGS. 1-4, of a roof design
according to the present invention comprises an external sheet
covering 1, that for instance may constitute sections of sheet
metal that are assembled in such a way that there is an overlap
between adjacent sections. In the embodiment according to FIGS. 1-4
the sheet covering 1 constitutes a sheet metal that has been given
a tile profile.
[0020] The sheet covering 1 is supported by an insulating layer 3
that preferably constitutes self-supporting cellular plastic.
Thereby, the side of the insulating layer 3 that faces towards the
sheet covering 1 has been given a shape that is adapted to the
sheet covering 1. Since the sheet covering 1 has a tile profile,
the side of the insulating layer 3 that faces towards the sheet
covering 1 has a shape comprising valleys and ridges. This brings
about that the sheet covering 1 is in tight contact with the
insulating layer 3.
[0021] As is evident from FIG. 4 the insulating layer 3 is in the
shape of prefabricated elements 5 that are mutually assembled by
cooperating connecting means along the edges of the elements 5.
When the prefabricated elements 5 are assembled in a correct way
they form a continuous bed upon which sections of sheet metal may
be located and assembled to create the sheet covering 1. When
assembling the elements 5 that constitute the insulating layer 3 a
continuous groove 9 is also created.
[0022] As is most evident from FIGS. 3 and 4 a flexible hose 7 is
embedded in the insulating layer 3. To that purpose the insulating
layer 3 is equipped with the continuous groove 9 that in the
disclosed embodiment has straight portions that are interconnected
by U-shaped portions. This groove configuration is of course only
an example of a number of feasible variants. Generally, the groove
configuration should be such that the hose 7/the groove 9 has an
extension covering a major part of the surface of the insulating
layer 3 that faces the sheet covering 1. The hose 7 may for
instance constitute a freeze resistant elastomer. In the groove
configuration shown in FIGS. 3 and 4 the groove 9 is located in the
valleys of the insulating layer 3.
[0023] The hose 7 may now be mounted in the continuous groove 9. It
is favourable if the hose 7 somewhat projects above the insulating
layer 3. When the sheet covering 1 is mounted on top of the
insulating layer 3 a perfect contact is established between the
hose 7 and the sheet covering 1, this improving the energy
exchange.
[0024] In FIG. 3 it is shown schematically, by means of the arrows
P1 and P2, how an energy absorbing medium is supplied at one end of
the hose 7 and discharged at the other end of the hose 7. The
energy absorbing medium preferably constitutes a liquid. If needed
an anti-freezing agent may be added to the liquid. The energy
absorbing medium is preferably collected in an accumulator tank
(not shown). The energy that is obtained during the day may then be
used during the night.
[0025] As is most evident from FIGS. 1 and 2 the insulating layer 3
is supported by a load carrying structure 10 that in the shown
embodiment constitutes tongued and grooved boards. The sheet
covering 1 and the insulating layer 3 are anchored in the load
carrying structure 10 by means of through-going screws 15 that
extend through the sheet covering 1 and the insulating layer 3 and
reaches into the load carrying structure 10.
[0026] The roof design according to the present invention also
comprises means to circulate a liquid in the hose 7. This may be
effected by means of a pump. Since a relatively large amount of
water may be circulated through the hose 7 the recovered energy,
preferably in combination with an accumulator tank, may be used to
heat tapwater and/or for floor heating. Of course an accumulator
tank is not necessary but the hose may be a direct part of a heat
exchange system.
[0027] In FIG. 4A a corresponding section is shown as in FIG. 4 of
an alternative embodiment of a roof design according to the present
invention. The principal difference between the roof according to
FIG. 4A compared to the roof according to FIG. 4 is that the hose
107/the groove 109 are located on the ridges of the insulating
layer 103. This means that contact between the hose 107 and the
sheet covering 101 occurs at the highest points of the sheet
covering 101.
[0028] In FIGS. 5 and 6 sections are shown through an alternative
embodiment of a roof design according to the present invention,
said embodiment generally being more suitable for industrial
buildings. A significant feature of the roof design according to
FIGS. 5 and 6 is that the sheet covering 201 essentially constitute
completely planar elements, e.g. of sheet metal, that are mutually
assembled by means of welts 202. The sheet covering 201 is
supported by an insulating layer 203 that also may have a
substantially planar surface that is equipped with grooves, said
surface facing the sheet covering 201. A hose 207 is received in
the grooves and liquid is brought to circulate in the hose 207 in a
corresponding way as described in connection with the embodiment
according to FIGS. 1-4.
[0029] Further examples of the design of a sheet covering, being
part of the roof design according to the present invention, is
shown in FIGS. 7-9. In connection therewith the insulating layer of
the roof design has been given a shape that is adapted to the sheet
covering. In FIGS. 8 and 9 the groove that receives the hose is
provided in the ridges of the insulating layer.
[0030] To sum up the roof design according to the present invention
offers a stable, insulating base for essentially all types of
roofing sheets, regardless if they are planar or corrugated. As
regards the material in the sheet covering reference is made to
what is stated under the headline Feasible Modifications of the
Invention. The roof design according to the present invention also
has a groove provided in the insulating layer, a hose being
received in said groove. Thereby collection and distribution of
solar energy is made possible.
Feasible Modifications of the Invention
[0031] In the embodiments described above the sheet covering 1;
101; 201 is preferably manufactured from sheet metal. However,
within the scope of the present invention it is also feasible that
the sheet covering is manufactured from other materials. Plastic
may be mentioned in exemplifying and non-restricting purpose.
[0032] In the embodiment described above according to FIGS. 1-2 the
load carrying structure 10 constitutes tongued and grooved boards.
However, within the scope of the present invention also other types
of load carrying structures are feasible. Secondary spaced boarding
or plywood may be mentioned in exemplifying and non-restricting
purpose.
[0033] In the embodiments described above the energy absorbing
medium constitutes a liquid. However, within the scope of the
present invention other energy absorbing media are feasible. Air
may be mentioned in exemplifying and non-restricting purpose.
