EP3388593B1 - Eaves capping for a tiled roof, method for applying said capping and building roof comprising same - Google Patents

Description

The present invention relates to a roof slop shutter dedicated to tiled roofs terminating in a sealed finish. It applies for roofs in all types of tiles, including channel tiles (tiles running and tiles covering or hat), Roman tiles, flat tiles, flat tiles of Marseille, rhombuses, ....

The present invention also relates to a method of laying said closet, and a building roof comprising it.

Such roofs are typical of an architectural heritage.

This type of roof is however doomed to disappear because of the regulatory constraints related to the thermal regulation and the use of a roof underlay. Under-roofing screens help to improve roofing performance: protection against snow and dust, wind resistance, waterproofing, insulation protection, as explained in detail in the review «The Artisan Building» N ° 570 - February 2017 - pages 45 and 46 and required by the regulatory text DTU 40.21 P1-1.

This by-law stipulates that under-roofing screens applied to the upper part of the framing lumber must not be closed at the bottom of the slope in such a way as to favor the ventilation of the underside of the roof and the evacuation of penetrations. accidental water, which in practice requires the use of a method of laying dry roofs and no longer to a sealed laying mode.

We know from documents JP 2002 349031 A , DE 200 09 597 U1 , DE 20 2010 009638 U1 and AU 85931 82 A roof drainage devices.

Patent documents are known GB 2 383 806 A , US 4,418,505 , US 2,962,745 low slope closures which are in contact with the outside by a closing wall at the end of the roof, the border tiles just bearing against the closure. The sealed installation mode is not allowed with this type of closures.

The present inventor has sought a solution to this problem and has developed a bottom of slope closure to respect the regulatory constraint by maintaining a sealed installation mode: free under-roof screen down slope, water recovery, ventilation in underface, invisible partition.

• l'aile ne comportant pas la paroi de fermeture est destinée à venir s'appliquer sur les voliges de la charpente et à être couverte au moins dans sa partie de bordure libre par la base de l'écran de sous-toiture, laquelle sera fixée à l'aile précitée ;

The present invention therefore firstly relates to a bottom of slope closure for a roof tile with a roof underlay and ending at the bottom of the slope with a sealed finish, characterized in that it comprises the characteristics of claim 1, in particular an elongated flat body made of a rigid material, folded along a longitudinal line to form two open V-shaped wings, one of the wings being folded along its free edge towards the internal space V to form a wall, said closure wall, which has openings which are spaced from each other and to each of which is connected a barbacan located outside the internal space V, where, in the mounting position of the closoir,

• the wing not including the closure wall is intended to be applied to the trenches of the frame and to be covered at least in its free edge portion by the base of the under-roof screen, which will be fixed to the aforementioned wing;
• the wing with the closing wall is intended to be applied, with their barbacans, on the upper surface of the wall or a cornice overlooking the wall facing the lower slope of the roof; and
• barbacans are intended to open out of the building, between the roof and the wall or cornice, being drowned in the sealed part of the bottom of the slope.

By barbacan means here an outlet tube of the infiltration water.

In the mounting position, the closure according to the present invention, with its barbican, is completely invisible, thus preserving the architectural character of the building, the building and its roof.

The rigid material of the closure may include aluminum, zinc-plated aluminum, zinc, steel or a rigid plastic such as rigid PVC.

The open angle of the V formed by the two wings may in particular be 180 ° less than the angle α which corresponds to the slope p of the roof. The angle α which corresponds to the slope of the roof and the slope (p) are connected by the formula p = 100 x tan (α). Thus, a slope of 30%, 33%, 35% corresponds to an angle α of respectively 16.699 °, 18.263 °, 19.29 °.

According to a particular embodiment of the closure according to the present invention, the closing wall is arranged at 90 ° with respect to the wing which carries it and is advantageously at least partly folded towards the internal space of the V along its free edge to form a stiffening flange of said closure wall.

• une pièce dite d'about droit Pad ;
• une pièce dite de jonction Pj ;
• une pièce dite de structure Ps ;
• à nouveau une pièce dite de jonction Pj ; suivie
• par une pièce dite de structure Ps ; en faisant suivre le cas échéant par au moins une succession d'une pièce de jonction Pj, puis une pièce de structure Ps ;
• une pièce de jonction Pj ; et
• une pièce dite d'about gauche Pag.

The closoir 1 is obtained by assembling the following successive parts:

• a so-called right-hand piece Pad;
• a so-called junction piece Pj;
• a so-called piece of structure Ps;
• again a so-called junction piece Pj; followed
• by a so-called piece of structure Ps; by following if necessary by at least one succession of a junction piece Pj, then a piece of structure Ps;
• a connecting piece Pj; and
• a so-called piece about left Pag.

In mounting position, as can be seen on the Figure 2a , the closoir 1 consists of an elongated flat body 2 folded along a longitudinal line to form a wing 3 and a wing 4 arranged in an open V, the wing 4 being, along its free edge, folded square towards the inside of the V, to form a so-called closing wall 5.

The closure wall 5 is folded square along its free edge except here in the vicinity of its two ends to form a flange 6 towards the inside of the V. Also, it has, at intervals, openings 7 to each of which is connected externally a barbican 8.

The barbican 8 is a tube of rectangular section whose base is formed by a large side of the rectangle and is located along the fold line between the flange 4 and the closure wall 5.

The closure 1 is closed at both ends by a fold of square 9 transverse edges along each wing 3 and 4, this fold being perpendicular to the closing wall 5, and itself being provided with an inward rim 10 similar to the flange 6.

An insect comb 11 (see Figure 1a ) is provided to be placed at the entrance of each barbacan 8 being pressed against the inner surface of the closing wall 5.

The closure 1 is made of a material such as aluminum, steel, galvanized steel, a plastic material such as PVC, Pad, Pj, Ps and Pag parts being all made from the same material, barbican 8 being integral, for example molded, parts Pj which carry them.

If we go back to Figure 1a it can be seen that the parts of each of the pieces Pad, Pj, Ps and Pag have been designated by the same reference numerals as those appearing on the Figure 1b , followed by the letters ad, j, s and ag, respectively. Indeed, each of these pieces has the same general shape as the finished 1 closoir that can be seen on the Figure 1a .

Thus, a piece Pj has two wings 3j and 4j, a closing wall 5j and its flange 6j. A room Ps has two wings 3s and 4s, a closing wall 5s with its edge 6s. The right abutment piece Pad has two wings respectively 3ad and 4ad, a closure wall 5ad and a transverse border fold 9ad with its flange 10ad. The same notation is used for the left end piece Pag.

• les pièces Pad ou Pag (voir également Figures 2a à 2f) ne présentent pas de rebord de leur paroi de fermeture et présentent, sur leur face inférieure, au voisinage des replis de bordure respectivement 9ad, 9ag, une bande adhésive respectivement 12ad, 12ag dont le rôle est indiqué plus loin. (Ces bandes adhésives n'ont pas été représentées sur la Figure 1a pour ne pas la surcharger) ;
• les pièces de jonction Pj (voir également les Figures 3a et 3b) ont leur paroi de fermeture 5j sur toute leur largeur excepté dans les régions d'extrémité et elles présentent, sur leur face supérieure, transversalement et de façon centrale, une bande adhésive 13j dont le rôle est indiqué plus loin. (Sur la Figure 3a, on peut voir que le rebord 6j est replié vers l'intérieur le long de sa bordure libre et que l'on y fait figurer les joints de silicone qui seront appliqués lors de la pose comme cela sera décrit dans ce qui suit) ; et
• les pièces de structure Ps (voir également Figures 4a et 4b) ont leur paroi de fermeture 5s sur toute leur largeur excepté dans leurs régions d'extrémité et elles présentent, sur leur face supérieure, au voisinage de la bordure libre de leur aile 3s, une bande adhésive longitudinale 14s dont le rôle est indiqué plus loin.

If we look at the Pad or Pag, Pj and Ps pieces individually, we can see that:

• Pad or Pag coins (see also Figures 2a to 2f ) have no rim of their closure wall and have, on their underside, in the vicinity of the edge folds respectively 9ad, 9ag, a band adhesive respectively 12ad, 12ag whose role is indicated below. (These tapes were not shown on the Figure 1a not to overload it);
• the connecting pieces Pj (see also the Figures 3a and 3b ) have their closure wall 5j over their entire width except in the end regions and they have, on their upper face, transversely and centrally, an adhesive tape 13j whose role is indicated below. (On the Figure 3a it can be seen that the flange 6j is folded inwards along its free edge and that the silicone seals which will be applied during the laying will be shown as will be described in the following); and
• the structural parts Ps (see also Figures 4a and 4b ) have their closing wall 5s over their entire width except in their end regions and they have, on their upper face, in the vicinity of the free edge of their flange 3s, a longitudinal adhesive strip 14s whose role is indicated later .

The adhesive strips 12ag, 12ad, 13j and 14s are, before mounting the closoir 1, covered by a peelable protective strip. It is also possible that these adhesive strips mentioned above are applied by the operator during assembly.

Holes 15 are made along the free edge of the wings 3j parts Pj and 3s parts Ps. Their role is indicated below. They can also be trained only at the time of assembly.

On the Figure 5 , there is shown between two pieces Pj carrying barbacans 8 a corner piece out Pa to use in the case of a roof having two adjoining sloping sides. The widths of the wings 3a and 4a must be respected to be in the extension of the wings respectively 3j, 3s, and 4j, 4s.

The outgoing corner piece Pa comprises wings 3a, 4a, a closing wall 5a and a flange 6a each forming an angle so that the corner piece Pa can cooperate with each of the adjacent pieces Pj. The closure wall 5a does not extend to each end of the wing 4a as is the case for the pieces Pj and Ps of the Figure 1 but the pieces Pj of the Figure 5 have a closing wall 5j which extends to the end of the wing 4j intended to interlock in the piece Pa.

• longueur d'une pièce de structure Ps : 1,5 m à 2 m
• longueur d'une pièce de jonction Pj : 33 cm
• longueur de chaque aile 3, 4 : 10 cm
• hauteur d'une paroi de fermeture : 3 cm
• longueur d'une barbacane : variable, pouvant être diminuée par découpe à partir de longueur de 10 cm
• largeur intérieure d'une barbacane : 6 cm
• hauteur intérieure d'une barbacane : 2,5 cm

As an example, we can cite the following dimensions for the closoir that has just been shown:

• length of a structural part Ps: 1.5 m to 2 m
• length of a connecting piece Pj: 33 cm
• length of each wing 3, 4: 10 cm
• height of a closing wall: 3 cm
• length of a barbican: variable, can be reduced by cutting from 10 cm length
• inner width of a barbican: 6 cm
• inner height of a barbican: 2.5 cm

We will now describe the assembly of the closure according to the Figure 1b starting from the parts of Figure la and with reference also to Figures 6a, 6b and 7 .

On a building whose walls M have been erected with or without a cornice C (see respectively Figure 6a where we showed the Jcorniche cornice joint, and Figure 6b ) and placed the vices V of the frame, one comes to put, at one end, the piece of right end Pad then successively the pieces Pj, Ps, Pj, ... Ps, Pj and Pag that one imbrrique ones in others.

The ends of the barbacans 8 have been cut out if necessary according to the structural recoil so that they come, in the installed closure, flush the seal S above the outer wall of the wall M or the cornice C.

In the example illustrated, the Pad, Pag pieces are not completely nested in the adjacent piece Pj, because the extent of the nesting is adjustable according to the total length of the slope of the slope which is variable of a roof to the other.

The piece Pj is slid by its wall 5ad in the return 6j of the neighboring piece Pj and wings 3ad, 4ad are placed on the wings 3j, 4j. The adhesive strips 12ag and 13j ensure the bonding. Silicone seals are disposed along the edges of the overlapping regions to seal the closure.

This progresses to the implementation of the left end piece Pag.

In the example shown, the connecting pieces Pj are completely covered by the structural parts Ps (except at the ends of the enclosure where they are partially covered), the silicone seals being applied to the edges of the pieces Pj (see Figure 3a ) and along the united edges of two pieces Ps (see Jsilicone of the Figure 1b ), and the bands 13j ensuring the bonding together parts Pj and Ps.

In the drawing, there are illustrated Pad, Pag, Ps and Pj pieces capable of nesting in a particular nesting mode. Other forms of room could be provided as soon as they can be interlocked to constitute the sealed complete closure of the invention.

In the example shown as well as for a closoir having an outgoing corner piece, barbacans were placed near the right or left end pieces or the corner piece. The other barbacans are placed in regular distances between the previous ones. This represents a particular embodiment, allowing a well-distributed water evacuation.

The pieces Pad, Pj, Ps and Pag are each time secured to the battens V by pointing through the holes 15 (all the holes have not been shown in the drawing).

Then we put the EST underlayment screen that is sticking along its base on the adhesive strips 14s on the closure that has just been placed.

The CL battens and the L beams of the framework are then laid.

The sealing mortar is then placed in the ZS sealing zone ( Figure 7 ), this mortar drowning the closoir, then we put the Tcourant running tiles which are sealed in the mortar which will form the S seal, then the hat Tchapeau tiles ( Figure 9 ) to form the first line of sewer tiles. The traditional laying of the other tiles is then performed.

The installation of a closoir at the bottom of the slope for a roof with several faces, is carried out in the same way, except that one replaces, as the case may be, at least one end piece with an outgoing corner piece.

The barbacans 8 ensure the flow of water outwardly and the ventilation of the roof on the underside.

The capping according to one of claims 1 to 5, characterized in that the weep holes (8) are formed in one piece with the closing wall (5) that carries them, and are able to be cut at their free ends to adjust their length along the frame withdrawal distance in order to position the capping relative to the tiles, the weep holes having to emerge in the sealed part of the eaves.
7. The capping according to one of claims 1 to 5, characterized in that:

   - in the case where it is intended to be placed at roof eaves with one or several non-adjacent slopes, it is closed by bends (9) of the two wings (3-4) toward the inner space of the V, at the two opposite lateral borders intended to be placed at the two respective ends of an eave; and

   - in the case where it is intended to be placed at a roof eave having at least two adjacent slopes, a protruding corner piece (Pa) is provided that tightly joins the two capping parts associated with the two adjacent eaves.
8. The capping according to one of claims 1 to 7, characterized in that the wing (3) not including the closing wall has, along its free border, screw passage holes (15) for fastening thereof on the battens (V) and has, if applicable, in the vicinity of its free border, longitudinal adhesive strips protected by an anti-adhesive strip for gluing of the base of the roof underlay (EST).
9. The capping according to one of claims 1 to 7, characterized in that it is formed in several pieces capable of connecting tightly to one another along transverse junction lined and of being secured to reconstitute a finished tight capping, said pieces advantageously being sized to overlap in their connecting zones, where:

   - in the case where the capping is intended to be placed at the eaves of a roof with one or two nonadjacent slopes, two butt pieces (Pad, Pag) are provided each including a bend of two wings of the capping toward the inner space of the V; and

   - in the case where the capping is intended to be placed at the eave of a roof having at least two adjacent slopes, a protruding corner piece (Pa) is provided,

   at least a portion of the pieces bearing a weep hole.
10. The capping according to claim 9, characterized in that outside the butt pieces and/or corner pieces, the pieces making up said capping consist of:

    - structural pieces each formed by a strip of material bent along a longitudinal line and forming two wings in an open V, one of the wings being bent along its free border toward the inner space of the V to form a wall called closing wall not including a weep hole; and

    - joining pieces, alternating with the structural pieces, with a shorter length than the structural pieces, with the same general shape as the latter but each including a weep hole, the structural pieces and the butt or protruding corner pieces being able to interleave with the joining pieces and to be secured thereto in particular by gluing to reconstitute a tight finished capping, the openings of the weep holes being left free during the interleaving of the pieces with one another, the span of the overlaps between the pieces, in particular between the butt pieces and the protruding corner pieces and the adjacent pieces being able to be chosen to adapt to the size of the capping in the assembly position, and the joining pieces advantageously being provided next to the butt pieces and/or the protruding corner pieces.
11. The capping according to one of claims 1 to 10, characterized in that an insect grate or comb is adapted against the closing wall (5) to extend in the opening region of a weep hole (8).
12. A method for placing an eaves capping as defined in one of claims 1 to 11, characterized in that it includes the following successive steps:

    - once the masonry walls with or without cornice are erected and the frame battens are installed, the capping is placed by successively placing its component pieces and producing the sealing gaskets between them, the wings of the capping not including the closing wall being pressed on the battens of the frame and being fastened thereto for example by screwing, the wings of the capping including the closing wall being pressed, with their weep holes, on the upper surface of the masonry wall or of the cornice overhanging the masonry wall, the weep holes having, if applicable, been cut to the necessary length to emerge just outside the building;

    - the roof underlay is placed, which covers at least part of the wings not including the closing wall, and said underlay is glued on said wings;

    - next, the counter-battens of the roof are placed, then the battens;

    - next, the mortar is placed for placement of the eave tiles, embedding the capping that has just been placed;

    - next, the tiles at the bottom of the slope are placed to form the first row of sewer tiles and the operations are continued to cover the roof.
13. A building roof including a roof underlay and an eave capping, said capping being as defined in one of claims 1 to 9,

    - the wing (3) of the capping (1) not including the closing wall being pressed and fastened on the frame battens of the roof;

    - the wing (4) of the capping (1) including the closing wall (5) being pressed on the upper surface of the masonry wall or of a cornice overhanging the masonry wall opposite the eave of the roof; and

    - the weep holes (8) emerging outside the building, between the roof and the wall or the cornice, in a sealed finishing region.
