[0001] In the building world the tile is one of least evolutionised but most solid products
in terms of the breadth of its uses and tasks.
[0002] From ancient times there exists a great variety, nearly all of them being deep-rooted
in their different areas of impact.
[0003] But nowadays specific materials (insulators, waterproof seals) have appeared that
seek to replace the traditional ones, thereby relegating them to an aesthetic end.
[0004] In this way there now exists a clear struggle between the new and the established
products that, in the case of the tile, results in it only having an architectural
style purpose - because it has an irreplaceable tradition - and is dependent on the
technical solutions of the new specific products.
[0005] This situation responds to the supposed efficiency lack of tiles as the only solution
to the necessities of a roof. But above all, this substitution comes from the need
of our society to use arguments of profitability to justify the application of various
products where traditionally only one was used.
[0006] The aim, however, of the present patent is to obtain a product that, with the simplicity
of the traditional product, has the qualities introduced by those newly appeared,
avoiding the use of a sum of products that would lead us to a clear increase in the
cost.
[0007] In this way, the whole of tiles that concern us should resolve, with great efficiency,
the waterproofing problems of the roof, entirely avoiding the negative incidents of
the effects of the wind, the mobility, the capillarity, the lack of resistance, and
at the same time, respond to the insulation, instalation and the maintenance.
[0008] We are going to define and analyse the distinct characteristics that a roof should
have and what is its technical state.
[0009] In this way the primary function of a roof is to collect the rainwater and drain
it completely to avoid water leakage into the interior of the building.
[0010] This function should be unified to the whole of tiles on a roof, that is , there
should be an interaction between the work of each one of them. Each tile collects
the water from the preceeding tile, and the water then flows over it until it reaches
the next one.
[0011] To achieve this end, in all the different kinds of tiles, an overlapping has been
defined that, with the help of the covering slope, permits the drainage from one tile
to another.
[0012] The overlapping should cover the union of the tiles both transversally and longitudinally,
or phrased in another way, it should cover as much between the courses (horizontal
disposition of the tiles) as between the lines (vertical disposition).
[0013] For the tiles with reliefs or waves, the common overlap is the superposition of the
transversal and longitudinal tiles. For the plane tiles the overlap is only made between
the edges, as it is necessary that a line of the tiles overlap to the two immediate
predecessors (respecting the slope), to achieve what is commonly called "to kill two
birds with one stone ".
[0014] In both cases the correct overlap (specified in due form) will stop , whatever the
causes , the water from being able to leak through the roof.
[0015] But it is true that frequently this function breaks down for reasons that have yet
to be fully resolved.
[0016] The most important of these reasons is the movement of the tiles (because of wind
action, birds or even of maintenance) that uncovers the overlaps or is the cause of
breaks. Another, very frequent one, although not solely attributed to the tile, is
poor instalation (bad props, the squares incorrectly dealt with, or incorrect fastening).
Also the passing of time , ice, fabrication defects, are all negative influences.
[0017] With this whole of tile being the object of this patent, we offer the only tile that
includes a double protection of the waterproofing face to combat these problems.
[0018] The solutions that come with this are common in whatever other tile, but for those
cases that, as we have seen, could have leakage, there exists a second level of overlapping
that acts entirely as a second independent covering which, can also protect against
the weather.
In this whole of tiles a single piece, made in huequeria (hollow ceramic piece), the
upper face that corresponds to the first covering of the primary roof body has its
overlappings defined and also incorporates the true aesthetic of the tile, as far
as it is its visible face.
[0019] Below this, the interior chambers defined by the hollow ceramic piece have the propriety
of being ventilation chambers, which considerably favour the dryness of the tiles
and notably help with the waterproofing.
[0020] There exist predecessors of tiles in hollow ceramic piece such as the " brick tile
", the " insulating tile " or the " hollow extruding tile ".
[0021] The base of the piece , which is plane to help the support (where some grooves in
the lateral arrises can be made to mount the tiles directly on the joints), functions
as an authentic second roof, with full capacity to drain the water which has leaked
from the upper faces of the pieces.
[0022] This draining capacity is attained by a characteristic overlapping of the surface,
defined by a prolongation of the sole of the posterior part of the tile and in this
way the sole of the upper tile can be assembled above this prolongation. In this case
the longitudinal (or between the lines) overlapping is not necessary but establishes
a corrugation of its own to induce the flow of water through the central zone of the
sole.
[0023] In being a characteristic of double waterproofing that most solidly defines this
product the whole of tiles that we are dealing with have other very interesting properties,
one of which, an absolute novelty, will be commented on at the end.
[0024] The first of these is the great resistance of the pieces. On being made from hollow
ceramic piece they have a structure which absorbs whatever force or pressure used
against them. This is strengthened by the good support on top of the board.
[0025] Another considerable advantage is the direct setting, that defines the passage of
the tile, that is, the longitude mount of the tiles, less its overlap. This permits
a very simple reopening and a fastening without nails or joining materials.
[0026] The insulation is a new advantage of this whole of tiles. Although it is a single
piece, it includes ventilation chambers, which give it an intermediate air passage
that works as the same time as the insulation. And not being airtight the air cannot
heat them.
[0027] The hollow ceramic pieces are known for their use of insulating packing materials.This
is unviable in the fabrication of tiles, because the ventilation qualities , a far
more important function , would be lost.
[0028] Only the " insulating tile " shares these three last advantages with the whole of
tiles that we are now presenting.
[0029] But, as has already been anticipated, this whole of tiles has one more exclusive
advantage, and an absolute novelty.
[0030] All the tiles with waves aesthetically imitate the so-called " Arab " or " Roman
". Their design tries to reproduce the visual effect of the combination of fluting
and coping tiles.
[0031] In this way, the mixed tile or " Roman" type has a defined curved fluting part and
a plane coping part.
[0032] The concrete tiles present different combination profiles of two parts fluting and
two parts coping.
[0033] But neither of these two achieve aesthetic independence from their distinctive pieces.
Both stay within the continuity of their line that varies in length, no doubt, obliged
by the determinants of the stacked overlapping.
[0034] The only progress in its pretension is to try and emphasize the shadows that reproduce
the deep characteristic of the distinct superplaced pieces.
[0035] In the whole of tiles now invented, it is possible to make the fluting and the coping
pieces clearly independent in terms of the aesthetic, keeping the join between them
defined by the aforementioned element of the hollow ceramic piece and which remains
hidden beneath the whole of tiles.
[0036] The key to this advance is that the overlapping is made facing or pointing towards
the pieces on the same longitudinal plane, not vertically as they do in all other
types of tiles.
[0037] Also, the design of a new form of cutting, a combination of wire cutting and blade
cutting, permits the volumetric cut that this whole of tiles requires.
[0038] As can be seen from everything described up until now, this invented whole of tiles
opens a new industrial path (tiles of hollow ceramic pieces with a double level of
overlapping), present unknown advantages for tiles.
[0039] Where nowadays complementary materials of insulation and waterproofing and joining
and fixing materials are used or, on the contrary, where traditional products of limited
characteristics are available, the employment of this complete and single whole of
tiles, with its low productive cost and instalation ease, all the problems related
to roofs are integrally solved.
[0040] In as much as the aesthetics which can be developed with this patent the possibilities
are endless.The freedom to use different pieces and profiles, from plane ones to wholes
of total curvature, gives us total aesthetic independence.
[0041] To round off the description and with the object of helping a better understanding
of the characteristics of the invention, we are going to make a detailed description
accompanied by a set of drawings, and where with a merely orientative object the following
is shown:
[0042] Figure 1 shows a posterior elevated view of the whole of tiles made according to
a form preferred by the invention, which includes two fluting tiles and two coping
tiles.
[0043] Figure 2 shows an upper plan view of the whole of tiles represented in the previous
figure.
[0044] Figure 3 shows a lateral elevated view of the same whole of tiles.
[0045] Figure 4 shows a lateral elevated view of two longitudinally overlapped modules or
wholes.
[0046] Figure 5 shows a plan view of the overlapping of the two wholes represented in the
last figure.
[0047] As can be seen from the figures, the module or whole of curved tiles, preferably
of " Arab" type, is made up of one or more fluting tiles (1) and one or more coping
tiles (2). All of them form part of a lower element of the hollow ceramic piece which
is determined by a lower supporting platform (3) and a series of vertical partitions
(4) which emerge from that platform.That is to say,(4) every two of them remain close
to each other, and the two most distant in respect to the other two adjacent. This
means that the upper edges of the nearest partitions make up half the support for
the coping tiles (2), so that the fluting tiles (1) remain situated between the most
distant partitions. This gives alternate levels of fluting tiles and coping tiles,
which is normal in the roofs with curved tiles.
[0048] Each whole or module of tiles, which will include at least one fluting tile (1) and
one coping tile (2), presents a lateral plane (5) and whose height and upper edge
will correspond to the lateral edge of a fluting tile (1), whereas that of the other
lateral (6) of the whole has the plane part of the lateral opposite and also one part
in the projecting lateral (7) of the corresponding coping tile (2).
[0049] On the other hand, the module constituted in this way previously presents an upper
projection (8), determined as a consequence that both the fluting tiles (1) and the
coping tiles (2) overlap in respect to their own anterior edge of the partitions (4).
All this has the objective of making possible the longitudinal projection of the modules
or wholes form a continuity, as can be seen in the figures 4 and 5. Also, a type of
visor overlaps the posterior edge of the platform (3), sticks out a visor (9) which
helps the contiguous longitudinal module avoid possible leakages when water flows
along the fluting tiles(1).
[0050] The hollow spaces (10) determined by the partitions (4), tiles (1) and (2) and the
platform (3) constitute a ventilation chamber to avoid the condensation and moistness
that could originate from the porosity of the ceramic material used. It also forms
an efficient insulating medium.
[0051] In the lateral overlapping of the wholes and modules, the lateral (5) of one will
lean against the lateral (6) of the other, while its projecting lateral (7) will remain
above it partially covering a wide upper band of the fluting tile (1) from the other
module or whole. That is to say, the tiles will stay laid out as if they were of the
same module or whole. In that case it depends on more than one pair as has occurred
in the realization.
[0052] In short, it could be said that the object of the invention is no other than to supply
the market with a unit of various joined tiles with an element of lower hollow ceramic
pieces.
[0053] Nevertheless, there exist risks of breaks during fabrication of the whole, due to
the corresponding to the fluting and coping tiles.
[0054] Likewise, the supports for the tiles on the surface of the roof, in some cases are
only made to support the extreme or posterior edge, and as the anterior support in
the immediate anterior in the tile is the classic form of support, tile breaks are
frequent. Also no uniformity exists in the forces produced in the supports, since
there normally exists a decomposition of the forces that could produce movements of
the tile, on having unequal support.
[0055] All these inconveniences are resolved by a variant of the described whole.
[0056] This variant, consists in that the support of each module on the surface of the roof,
functions by means of lower longitudinal ribs, that decrease progressively in height
from the anterior edge to the posterior edge of the module. A rib corresponds to each
partition included in the module. This new characteristic gives the unit an uniformity
in support and a greater resistance, avoiding cracks and possible movements. Another
variant consists in that the fluting tiles, instead of being concave, are formed from
a plane part extending between the two corresponding partitions, which also provides
a greater resistance to cracking, in the process of fabrication.
[0057] This and other characteristics, such as the windows and features derived from the
same, will be better understood in the description which is going to be carried out
shortly with the help of the figures 6, 7, 8, and 9.
[0058] Figure 6 shows an elevated posterior view of a module or whole of tiles which includes
two fluting tiles and two coping tiles.
[0059] Figure 7 shows a view plan of the same module or whole of tiles represented in the
preceeding figure.
[0060] Figure 8 shows an elevated lateral view of the module or whole represented in the
preceeding figures.
[0061] Figure 9 finally shows the elevated lateral view of the longitudinal overlapping
between two modules or wholes, as its represented in previous figures.
[0062] As can be observed, the whole or module, that defines the curved tile, " Arab " type,
includes a lower platform (11), rectangular and plane, from whose upper face pairs
of ribs (12) emerge vertically. Depending on the number of tiles there will be one
pair, two pairs or more. We can see included a pair of central ribs (12), a pair of
ribs (12') in a lateral and a rib of greater height (12''), in the opposite lateral.
[0063] The distance between the ribs (12) or (12') of each pair is reduced, whereas the
distance of each one of those in respect to the corresponding contiguous rib to another
pair is considerably greater.
[0064] Between the ribs (12) or (12') of each pair a plane surface determines the fluting
tiles (13), whereas between the rib (12) of one pair and the rib (12') of the other,
or put better between the other rib (12) and the rib (12'') of the opposite lateral,
the coping tiles are determined (14).
[0065] The fluting tile (13) of a lateral is at the top of a ledge (15) to stop water escaping
towards the lateral, whereas the coping tile (14) of the opposite lateral overlaps
in a small projection (16) all along the module or whole.
[0066] Corresponding to the previously cited ribs, and in opposition to them, other ribs
have been anticipated (17) that emerge from the lower face of the platform (11), ribs
(17), that get progressively smaller from the extreme anterior to the extreme posterior,
and in this fusing with the edge of the platform (11).
[0067] Such ribs (17) constitute the support of the tile module or whole on the surface
(18) of the roof, proportioning the correct stabilisation and inclined support to
the module on this surface (18).
[0068] For the anterior parts that form the fluting tiles (13) and the coping tiles (14)
a projection juts out to permit the transversal overhanging,(19) whereas the longitudinal
overlapping is achieved by means of the projection (16) of the coping tiles (14) over
the edge (15) of the opposite lateral.
[0069] Between the tiles, ribs and the platform passages or hollow ceramic pieces that give
origin to the ventilation chambers are fixed. Being open both at the front and at
the back, they also fix a double waterproofing, one originated by the tiles and the
other by the platform.
[0070] The module or whole depends on a reduced zone or recess (20) in the extreme posterior
of the projection (16) of the coping tiles (14), prepared to achieve a perfect longitudinal
and transversal coupling in the overlap, in the confluence link between the four modules
or wholes.
1. Whole of tiles, fluting and coping, with a double waterproofing body and with both
a transversal and longitudinal overlap, is preferably formed with a ceramic material
and where possible made to overlap laterally and/ or longitudinally with other analogues
to form a continuous roof with corresponding slope. It is characterised essentially
in that, obtaining by extrusion, it is made up of a lower part determinant of, at
least, a fluting tile and a coping tile.This means that the element or part of the
hollow ceramic piece is determined by an inferior plane support platform, and a plurality
of emergent vertical partitions of the same, in such a way that a fluting tile remains
situated between each partition. However the upper rim of one of those two partitions
and the upper rim of the other partition stay closer to the anterior, than the existent
separation between the first pair of partitions. This constitutes a support for the
coping tile, leaving this on a higher level than the contiguous fluting tile. This
means that among such tiles, partitions and the lower platform open hollows are fixed
at the front and the back, forming ventilation and insulating chambers.
2. Whole of tiles, fluting and coping, with a double waterproof body and with both a
transversal and longitudinal overlap, in accordance with the claim 1, characterised
in that the fluting tiles and the coping tiles jut out in projection in respect to
the vertical partitions and the lower platform, to make the longitudinal overlap with
the other analogous whole possible.
3. Whole of tiles, fluting and coping, with a double waterproof body and with both a
transversal and longitudinal overlap, in accordance with the previous claims,characterised
in that the posterior rim of the platform is extended in a type of visor to support
the other whole overlapping longitudinally with the first to form a second waterproofing
body.
4. Whole of tiles, fluting and coping, with a double waterproof body and with both a
transversal and longitudinal overlap, in accordance with previous claims, characterised
in that one of the laterals is plane and reaches a height that corresponds with that
of the lateral edge of the fluting tile, whereas that of the other lateral, also being
plane, presents an upper part of the projection that belongs to a coping tile to permit
the lateral overlapping between wholes and to determine a continuity in the construction
of the roof.
5. Whole of tiles, fluting and coping, with a double waterproof body and with both a
transversal and longitudinal overlap, in accordance with previous claims, characterised
in that the fact that corresponding with the support partitions of the tiles, and
in opposition to them, other such vertically emergent partitions from the lower face
of the platform have been shown, being those lower partitions diminishing progressively
in height from the extreme anterior to posterior part, determining some means of continuous
support of the module or whole on the inclined surface support of the roof.
6. Whole of tiles, fluting and coping, with a double waterproof body and with both a
transversal and longitudinal overlap, in accordance with the claim 5, characterised
in that fluting tiles are plane and remain disposed in a lower plane to the coping
tiles, between the partitions of each of those shaped in the module or whole.
7. Whole of tiles, fluting or coping, with a double waterproof body and with both a transversal
and longitudinal overlap, in accordance with the claims 5 and 6, characterised in
that the lateral edge of the fluting tile determined in one of the laterals of the
module, presents an upward rim for the canalisation of the water and the overlapping
of the corresponding projection to the coping tile of the opposite lateral.
