Algeroz to be incorporated in the roofs with hollow roof tiles and a roofing process that includes the use of such downspouts

The present invention relates to downspouts to be incorporated

on roofs that comprise a hollow roof covering, as well as a process for assembling such gutters on existing roofs or on new roofs under construction.

There is a need, or even a legal obligation, to collect run-off water from roofs in order to protect walls, foundations and, in cities, passers-by. This collection is done in general with the help of gutters or downspouts placed on the water's edge of the roof.

From an architectural point of view, the gutters have the great advantage of covering the upper part of the cornices or trim that crown the buildings. Gutters, which perform the same function as gutters, but which are placed on top of the cornices, present risks of infiltration. It is true that there are gutters, called English (or gutters> English), that avoid the risks of infiltration, but their very visible presence on the edge of the roofs is very damaging to the aesthetics of the building. In certain cases, gutters and gutters are not only unsightly but also anachronistic considering the time or architectural style of the building.

So there has been a need for a long time to avoid the unaesthetic and / or anachronistic presence of a gutter or a caη

ç.

evacuated later by a descent pipe.

The object of the present invention is roof gutters which are intended to be integrated and concealed in a roof tile with hollow tiles, thus satisfying the requirements mentioned above.

Another object of the present invention is the process

placement of such a downspout, preferably at the bottom of the cover,

According to one of its aspects, the present invention provides for a roof water covered with hollow tiles arranged in a series of alternating rows of current tiles and roof tiles forming a regular and repetitive pattern that determines a length of wave, a downspout that comprises a globally sink bottom not between a downstream longitudinal wall and an upstream longitudinal wall and, connected to the downstream longitudinal wall, a corrugated strip adapted to cover the chain tiles covered by the roof tiles.

A corrugated band thus conceived makes it possible for all of the current tiles to be covered and the roof can proceed without interruption. Thus, roof tiles can cover a good gutter layer by themselves, which

Downspouts according to the present invention can be carried out by cutting, bending and welding metal sheets, or by molding any suitable plastic material or with a

said wavelength, each element being closed at the ends by a terminal transverse wall connected to the longitudinal wall downstream in the vicinity of a Christian of the band on'du lada and with at least one descent hole in each

ment.

The advantage of providing for the closure of the ends of the downspout by terminal transverse walls in the vicinity of a Christian of the wavy band, lies in the fact that the said transverse walls are concealed under roof tiles. In addition, several gutter elements so closed can be placed in the

with each other with free expansion spaces, if necessary, under cover tiles.

algeroz will be advantageously constructed in such a way that the average plane of the corrugated band according to the present one. the invention forms with the bottom plane of the algeroz an acute angle roughly equal to the angle of inclination of the current tiles on the general plane of the roof water.

The width of the corrugated band that will come to cover the so-called resumption of current tiles may advantageously be between one seventh and one third of the length of the tiles, which proves to be convenient to ensure a good tightness.

The present invention also aims at a roofing process which comprises the placement of said downspouts, characterized in that the rows of chain tiles are interrupted in the downspout of the downspout and then resumed, on the downstream side, by chains of so-called chain. resumed, covered by the wavy band

while the roof tile fiacles continue. without discontinuity.

According to another aspect of the present invention, in the process of placing such downspouts, the bottom of the downspout is placed directly on the rafters of the roof lumber thanks to a corresponding interruption of a current lath on the upstream side, this interruption being followed by a resumption of a fan

with over-thickness on the downstream side, ensuring this over-thickness a continuity of aspect of the roof: this process allows the realization of a virtually invisible downspout and, therefore, with a great aesthetic interest, while offering the advantage of increasing the retention capacity for draining rainwater in the descent pipes associated for this purpose to each element.

The characteristics and advantages of the present invention will moreover be more evident in the description that will follow, by way of example, with reference to the attached drawings, whose figures represent:

According to the embodiment represented by figs. 1 to U, for a roof with channel tiles, a roof that includes a lath or slats (10) laid in the usual way on the lime, bridges (11) of a wood (not shown in detail) is covered by tiles. channel in rows (12) of chain tiles based on the slats (13), alternating with the rows (ih-) of roof tiles that partially cover them, forming the rows' a

regular and repetitive motif that determines a wavelength

Since the lath is interrupted in front of a hood (15), a gutter (20) is placed directly on the rafters (11), being guided by a terminal lath (16) of two layers, in turn terminated by an end cap (17) water from the roof. The bottom of the gutter is supported by a bar (110) resting on chases (111) nailed to the face of the rafter. The term eaves bar is generally used in the language of roofers to designate the barges such as (15) and (17) , while the support element (110) of a gutter bottom is called phonecure.

The downspeed (20) according to the present invention has a planar feature (21) that extends between a longitudinal wall of monent (22) and a longitudinal wall of downstream (2U) in a width (Ll) that corresponds substantially to the length of a tile and

which varies depending on the slope of the roof. In the case in question, a gutter made of a plate, the upright wall (22) ends with a straightened edge (23) smoothed and rigid by a sheet fold. The downstream wall (2 ^) ends, in turn, with a straight edge (2%) cut according to a wavy layout, whose sinusoidal shape is adapted to match the profiles of the roof channel tiles. A corrugated band (26) is connected to this wavy edge (26), of a strength O ^{: S s} i ^nus ° ic! Al, which extends over a width (L2), for example, between one third and one quarter of the width (Ll) of the gutter and ensuring in the last budget of tiles downstream a sufficient covering.

In the longitudinal direction, the gutter can extend for any distance, usually several meters, depending on the dimensions of the roof water to be equipped and the dilation coefficient of the material used, and always comprises at least one opening at the bottom ( 27) connecting to a water drop pipe (23)

rainwater, making this connection in general by means of a section of tube (28 ') welded on the edge of the opening. The downspeed can advantageously be subdivided into elements of appropriate length, with at least one opening (27) per element. Each element being delimited at each of its ends by a terminal transverse wall (29), it is always located in front of a vertex of the edge undulation (2%) [or a Christian (33) of the wavy band (26)] so that the length of a downspout element according to the present invention will advantageously correspond to an integer multiple of the wavelength Xj of its corrugated plate (26).

As is still visible in fig. * +, the angle (A) formed by a g-eratriz of the wavy band (2c) with. the downstream wall plane (2à) of the downspout is an obtuse angle: the generatrix in question (or the median plane of the wavy edge) is oriented, in effect, approximately parallel to the general direction of the current tiles ( 12), which direction forms an acute angle (a) (fig. 1) I ran the general plane of the roof water. Therefore, the same angle of inclination (a) is found again between the middle plane of the corrugated edge (26) and the flat bottom (21) of the downspout.

Each row (12) of chain tiles is interrupted at the downside of the downspout: a tile such as ¢ 21) is laid down by its downstream part in the hood (15) and the upstream wall (22) of the downspout will defuse the bottom (21) of the latter of a distance that corresponds substantially to the current covering of the successive tiles. in each row. Each chain tile (121) is thus adapted to release the runoff water that reaches it. The next chain tile of the row, that is to say (122), will thus be inserted between the corrugated band (26) of the downspout and the lath pias (16). The course continues and then ends normally with one or more chain tiles (123) terminating the roof.

The thickness of the double lath (16) and the corresponding height of the downstream wall (2à) of the downspout are advantageously chosen dgs in such a way that the position in the space of the so-called resumption chain tile (122) corresponds substantially to the position in which this tile would be placed in the absence of the downspout in an interrupted row.

Thanks to this arrangement, the appearance of the roof as a whole is practically unchanged and the gutter is almost invisible, since the arrangement and continuity of the rows (1U) of roof tiles are intact.

the relative increase that results, on the other hand, from the

Γ8 of the downstream wall (2U) of the downspout contributes to increase the retention capacity of the latter, so that the risk of overflow to the terminating current tiles (122,123) is not to be feared except in the case of exceptional rainfall. However, the multiplicity of flow paths constantly available over the curled rim constituting the same is well a backup or even a guarantee against the risk of entu Pepper gutter by solid materials, nomeademente ori © ^{No vegetation} ^ (t ^ol h ^{the and} other things) that could tend to be deposited there, since the access to the gutter for these materials is also severely limited thanks to their protection by the roof tiles.

As can be seen clearly, in particular in fig. 3? the downstream network (2U) of the downspout ensures a closure of the access to the space, located below the resumption tiles (122) and the corresponding current tiles. The same does not happen on the side of the wall

upstream (22) whose upper edge (23) is straight and follows the top face of the hood (15) on which they rest, the last chain tiles (121) of the rows (12) of chain tiles: the access is like this open between the support areas of the chain tiles, which ensures the desirable ventilation of the underside of the roof.

According to another embodiment of the present invention represented by figs. 5 to 3, for a Roman tile roof, a roof comprising a lath (210) laid in the usual way on the rafters (211) of the roof lumber (not detailed) is covered with tegules in rows (212) alternating with rows. of overlapping tiles (21U) that partially cover them, forming the rows in a regular and repetitive pattern that determines an À2 wavelength ·

continuation of the lath and whose thickness grows in the upstream and downstream direction having an upstream thickness equal to the uniform thickness of the chilled phase. A copper gutter (220) rests directly on the bridges (211) and is followed by a terminal lath (216) which is continued by an end cap (21?) Of the roof water. The latter cap also has a thickness that grows upstream and downstream with a thickness equal to the uniform thickness of the lath. The gutter (220) according to the present invention has a globally flat bottom (221) that extends between an upstream longitudinal wall (22b ·) and a longi wall. downstream tudinal (22b-) in a length (L3) that corresponds to approximately half the length of a tile and that varies by. tilt of the roof. This bottom (221) has reinforcement ribs (300) constituted here by folds joined by the small amplitude edges protruding from the outer wall of this bottom. These ribs extend according to the length of the downspout and parallel to the longitudinal walls (222,22b-). By giving rigidity to the gutter joint between two successive rafters, these ribs prevent the additional seating of a support bar placed on hoods as in the case of the previous embodiment. The ribbed gutter is therefore self-supporting. In the case of a gutter made of copper plate, the upstream wall (222) and terminated by a straight edge (223) smoothed and rigidized by a fold of the plate. The downstream wall (22b ·) is, in turn, terminated by a straightened edge (225) smoothed and rigidized by a fold of the plate. The height (H) of the downstream wall is substantially equal to the value obtained by adding 10 the thickness of the lath (216), two thicknesses of tegula and the thickness of the plate.

A corrugated strip (226) having a rectangular shape is welded, in a globally parallel manner, to the edges (223,225) of the downspout, outside the downstream wall (22U). This wavy band features rectangular platforms

flat, bottom (230) and upper (231) perpendicular to sink in the downstream wall (22U) and the upstream wall (222) and downstream ^(1¼ 22) substantially perpendicular to the bottom (221).

The lower platforms (230) queform _the m cavities of the corrugated strap are fixed at a distance (h) from the bottom (221) equal substantially to the sum of the lath thickness (216) and a greed okay, so that cover, lightly touching it, the bottom of the downstream tégulas (323) called resumption, next to the downstream wall (22U) of the downspout. The upper platforms (231) that form the Christians (232) of the wavy band are located at a distance (i) from the bottom (221), roughly equal to the sum of the thickness of the lath (216) and the edges of a tégula, in a way to cover these edges, however they can be covered by overlapping tiles (32 ¹ ¼).

This corrugated strip (226) extends along a length (iA) between one seventh and one third of the length of the tile used and ensures a sufficient covering of the downstream tiles (323) ·

In order to better conceal the gutter, each of the lower platforms (230) is covered with adapted pieces (322) that are substantially identical to the tégula cut with the straight edge. These pieces (322) are in the alignment of the upper pieces (321) of tégula that defoam the gutter. Between each piece

(322) a piece (320) missing by dashed lines is already missing. Pieces (322), (320) and (321), joined in this order, would reconstitute an entire tegula. The missing piece (320) ensures a discontinuity in the rows of tegula, which allows to collect in the downspout the runoff water from the mountain top

this discontinuity. The adapted pieces (322) are held in place on lower platforms (230) by rows of overlapping tiles (32 * +) that cover them.

In the longitudinal direction, the gutter can extend for any distance, usually several meters, depending on the dimensions of the water of the roof to be equipped and always comprises at its bottom at least one opening (227) connecting to a pipe (228 ) of rainwater descent, this connection being made in general by means of a section of pipe (228 ') that surrounds the opening (227).

As in the previous embodiment, the gutter can be advantageously subdivided into elements of appropriate length with at least one opening (227) per element. Each element delimits

at each of its ends by a transverse wall (229), the latter is preferably located in front of an upper platform (231) forming a Christian (233) of the wavy band (226) in order to be better concealed through the row (21 ¹ ¼) of corresponding overlapping tiles, which passes seamlessly across the straight edge (232), upper edge of the transverse wall (229).

In this embodiment, if there is no overflow, the alge roz works in the same way as in the first embodiment. In the event of gutter clogging, the downstream wall (22 ¹ ¼) of the aX geroz does not close the access to the space located downstream of this wall (22 ¹ ¼) and under the overlapping tiles (32 ¹ ¼) and hs shortened overlapping tiles (325) · It is therefore advisable to seal the spaces (326) between the edges of the tiles downstream of the gutter with mortar, to avoid the possibility of water infiltration into the terminal lath (216) and / or the extremi hood.

(217). A slightly rounded shape can also take place, even in a circular arc, Is upper platforms (231). in order to relaunch the waters on each side to the lower platforms (230).

It is evident that the present invention is not limited to the details of the embodiments which have just been described by way of examples. Thus, instead of being made of sheet metal, downspouts can also be manufactured by molding any suitable plastic material or even a cement-based mixture, such as asbestos-cement. Production will generally be organized in elements of standard lengths, for example between 2 and 10 meters. One can also envisage continuous manufacturing with cut to

each case of channel tiles, the tiles being able to be laid in parent. corrugated asbestos cement or similar. In general, the elements can be terminated by transverse walls perpendicular to the longitudinal walls, but at the junction between two different waters, it will, of course, be possible to provide transverse walls forming an appropriate angle with the longitudinal walls.

Does the orientation need the wavy band in relation? longitudinal wall could result from a deformation in the assembly, in the case of construction elements of easily deformable materials, such as copper or zinc sheet, for example.

In the same way, the reinforcement ribs at the bottom of the downspout may be replaced by small amplitudes whose Christians and armholes form lines of longitudinal orientation.
