Description

The present invention relates to an intermediate piece intended to be placed on adjacent battens of a roof so as to support covering means.

More specifically, the invention relates to a spacer intended to be placed on adjacent battens of a roof, usually two adjacent battens, so as to support flat covering means, including slates and / or flat tiles, positioned adjacent and to improve the tightness of the assembly thus formed, of the type comprising an oblong core which has an upper face capable of supporting said covering means and a lower face and which is provided with transverse edges and longitudinal edges, these the latter having distal portions of folded edges.

It has been described in the patent EP 0710314 an intermediate piece, intended for supporting slates or tiles, whose corrugated core comprises portions of longitudinal edges provided with notches for attachment to a roof batteau and one of the transverse edges is provided with tabs for retaining the transverse edges of two tiles or slates positioned adjacent to said piece.

This however has the disadvantage of use in relation only with metal battens given the notch configuration of the means provided for attachment to them. In addition, this piece reveals, in use, poor weathertightness and corrosion problems occurring in the bent portion or in the portion that extends over the lower ends of a slate or flat tile.

Similarly, it has been reported in the patent application WO03 / 023164 a piece for supporting tiles on adjacent battens of a roof whose upper face has at least two seals, one in the form of a bead inserted in a groove running along the longitudinal edges and a transverse edge of the piece, the other in the form of a transverse strip overlapping the longitudinal axis of this piece. On the other hand, it is also provided with a transverse flange for attachment to a first batten and longitudinal edge portions having notches for attachment to a second batten. Furthermore, this piece is also provided with a wire hooking tiles, this wire having ears adapted to fit into openings in said flanges.

The part in question however has several disadvantages including the need to use a tile fastening means not commercially available and which, for this reason, must be manufactured expressly, which costs the cost. In addition, the means of securing to the battens prevents attachment to traditional wooden battens but requires metal battens with a particular profile.

The purpose of the present invention is to propose an intermediate piece capable of improving the attachment of slates and / or flat tiles to the battens of a roof, this piece being inexpensive, easy to manufacture, flexible and flexible in use since it can be considered in relation to both wooden and metal battens, while offering a particularly effective seal.

To achieve this purpose, the part of the type indicated above is characterized in that the core comprises at least four portions of non-folded longitudinal flanges forming wings, generally four portions of flanges of this type, for a securing of said piece with two battens adjacent, the portion of these wings adapted to provide this fixation being located in the plane of the soul or in a lower plane parallel thereto.

In the context of the present description as in the claims, the terms "distal" and "proximal" will be used to designate a position of an element or component of the part, respectively the furthest position and the position the closer to the transverse end of the soul which, when the soul is attached to two adjacent battens uneven of a roof, is at a level below the second transverse end.

• « partie, zone ou extrémité distale de l'âme », la portion d'extrémité transversale de l'âme en contact avec le liteau de niveau supérieur dans un recouvrement de toiture en pente, par « partie ou zone intermédiaire », la portion de l'âme située au niveau du liteau adjacent de niveau inférieur et par « partie, zone ou extrémité proximale de l'âme », la portion d'extrémité transversale située en contrebas de ce liteau de niveau inférieur,
• « face supérieure», une face tournée en direction des ardoises ou tuiles plates à supporter et par « face inférieure», une face tournée en direction des liteaux de toiture,
• « rebord replié », un rebord issu d'un bord de l'âme de la pièce et plié à environ 90° en direction de la face inférieure et « rebord non replié », un rebord issu d'un bord de l'âme de la pièce et situé dans le plan de cette âme.

Thus, we will designate for example by:

• 'Part, zone or distal end of the web' means the transverse end portion of the web in contact with the top level battlement in a sloped roof covering, 'part or intermediate zone', the the core located at the level of the adjacent lower level batt and "part, zone or proximal end of the web", the transverse end portion situated below this lower level batt,
• 'Upper face' means a face turned towards slates or flat tiles to be supported and 'lower face', a face turned towards the roof battens,
• "Folded edge" means a rim from one edge of the web of the workpiece and bent at approximately 90 ° to the underside and "non-folded edge", a rim from an edge of the web of the room and located in the plane of this soul.

Usually, the part according to the invention can be made of any metal conventionally used in connection with roof reinforcements, for example made of preferably stainless steel, zinc, copper or a rigid synthetic polymeric material. This piece comprises four wings grouped in pairs, each pair of wings being intended to overlap a batt for its attachment thereto, namely a pair of distal wings in the distal zone of the soul and a pair of wings. proximal wings in the middle zone of this soul.

Advantageously, the proximal wings will be uneven in a lower plane relative to the distal wings.

Consequently, according to another characteristic of the invention, the insert has two distal wings located in the plane of the soul and two proximal wings, possibly provided with support feet, uneven in a lower plane.

These support feet come, in general, a folded longitudinal rim portion of which an end section is curved externally to the workpiece.

In addition, the difference in elevation in particular makes it possible to soften the slope of the flat covering means when it is placed on the part according to the invention itself fixed to roof battens uneven in opposite directions. Moreover, this difference in elevation of the proximal wings is particularly advantageous when this fixation of the part at its intermediate zone is carried out by means of traditional double hooks, of the hook-and-hook type, which are preferably positioned not between slates or flat tiles but beneath them. When positioned under a slate or a flat tile, the double hook is usually associated with a means for its restraint, a medium secured to the soul. For this reason, the unevenness of the wings relative to the plane of the soul is at least equivalent to the thickness of the retaining means in relation to the stem of this double hook, as will be explained in more detail later.

Usually, the wings come from an extension of the plane of the upper face of the soul, the wings located in the intermediate zone or proximal wings being provided with support feet capable of causing this unevenness of the intermediate zone with respect to the distal zone .

However, when they are located in a plane lower than that of the soul, these proximal wings usually take an L configuration, that is to say at right angles.

According to a first preferred embodiment, the part according to the invention is devoid of means for its attachment to roof battens.

In this case, each wing is provided with at least one orifice. These orifices are intended for the passage of any means for fixing the intermediate part to roof battens, namely a totally independent means of this part, for example a screw, a slate nail or a hook with staples.

Similarly, the core of this intermediate piece may also present, in its distal zone and along its longitudinal axis, an orifice which allows the passage of a means for attaching a covering means, by for example, a pointed hook for hanging a slate or a flat tile. However, this piece may, if necessary, present in place of this orifice, a nipple emerging from the upper face of the soul. This nipple is intended to be pierced during the passage of the attachment means, causing the crushing of said nipple and consequently, increased sealing.

Advantageously, the upper face portion of the wings and the core that could be made to support the passage of a hook tip or the like will be grooved so as to insert this hook at least partially in the wing or in the soul and thus avoid excessive overflow of this hook above this face.

According to another preferred embodiment, the part according to the invention comprises both own means for its attachment to the battens and own means for the retention of these attachment means. These retaining means can be reported on this part or, preferably, from it. In such a configuration, the orifices provided at the wings may be present or absent.

Thus, according to another characteristic of the invention, the intermediate piece is provided with means for attaching it to a batten, means consisting of double hooks each comprising a rod provided with a distal end loop capable of cooperating with a batten of roof and a proximal end loop adapted to cooperate with a flat covering means such as a slate or a flat tile.

Typically, this double hook or "hook hook" is in the form of a rod, generally metallic, whose ends are provided respectively with a distal loop and a proximal loop, also metallic, taking place l one and the other in the same plane and in opposite directions. This double hook can be secured to the intermediate part, by means of a support means, which can take different forms depending in particular the material used for the production of this part.

Thus, according to a further feature of the invention, each double hook is secured to the intermediate part by means of retaining means forming tongs, these tongs being derived from portions of folded or non-folded longitudinal edges.

In addition, according to a particularly advantageous feature of the invention, each double hook is retained by a distal clip substantially perpendicular to the lower face of the core and by a proximal clamp substantially parallel to the longitudinal axis of the soul and to the underside of it.

According to another embodiment of the intermediate piece according to the invention, a first portion of the distal loop of the double hook, generally a portion substantially perpendicular to the lower face of the core, is secured to a distal gripping clamp reported on the piece or, preferably, stemming from the soul of it.

1. a) soit sous la forme d'un S dont la boucle dirigée vers l'extrémité proximale de l'âme est apte à enserrer la boucle distale du double crochet, soit sous la forme d'un U dont l'unique boucle dirigée vers l'extrémité distale de cette âme est apte à enserrer cette boucle distale.
   De telles configurations sont avantageusement utilisées lorsque la pièce intercalaire, selon l'invention, est réalisée en métal.
2. b) sous la forme d'une rainure ou cannelure pratiquée dans ladite section terminale recourbée, rainure apte à loger ladite boucle distale.

Advantageously, this distal clamp is derived from a portion of folded longitudinal edge of which an end section is curved externally to said part, this clamp being:

1. a) in the form of an S whose loop directed towards the proximal end of the core is able to grip the distal loop of the double hook, or in the form of a U whose single loop facing the distal end of this soul is able to grip this distal loop.
   Such configurations are advantageously used when the insert, according to the invention, is made of metal.
2. b) in the form of a groove or groove formed in said curved end section, groove adapted to accommodate said distal loop.

Usually this groove or groove is designed perpendicular to the underside of the core. In addition, an embodiment of this type is generally reserved for an intermediate piece made from a rigid synthetic polymeric material.

In the embodiments described above, the distal loop of the double hook for hanging the lower batt of a pair of adjacent battens is located under the plane of the underside of the core.

Together, a second portion of the distal loop of the double hook, portion substantially parallel to the longitudinal axis of the web of the part and the lower face thereof, is also secured to a proximal clamping clamp reported on the room or, preferably, resulting from it.

1. a) d'une portion de rebord longitudinal replié qui subit une première courbure jusqu'à créer une pince apte à enserrer la boucle distale du double crochet, puis une seconde courbure jusqu'à créer une aile proximale.
   Ce type de pince est, en général, réservé à une pièce intercalaire fabriquée en métal.
2. b) d'une rainure ou cannelure pratiquée à partir de la face inférieure d'une aile proximale, y compris de son pied support, et apte à loger ladite boucle distale du double crochet.
   Habituellement, cette rainure ou cannelure se présente sensiblement parallèle à l'axe longitudinal de l'âme.

Usually, this proximal clamp is formed:

1. a) a portion of folded longitudinal rim which undergoes a first curvature to create a clamp adapted to grip the distal loop of the double hook, then a second curvature to create a proximal wing.
   This type of clamp is, in general, reserved for a spacer made of metal.
2. b) a groove or groove made from the underside of a proximal wing, including its support foot, and adapted to accommodate said distal loop of the double hook.
   Usually, this groove or groove is substantially parallel to the longitudinal axis of the core.

As in the case of the distal forceps, this embodiment of a proximal clamp, in which a groove or groove intervenes, is used more in connection with an intermediate part made of a synthetic polymeric material.

In these various embodiments involving grooves or grooves, the insertion of the distal loop of the double hook may be reinforced by means of any additional means which may consist for example of a bonding or welding.

In addition, in the embodiments of the proximal clamp described above, the portion of the distal loop of the double hook, portion substantially parallel to the lower face of the core, is preferably located under the plane of this face. lower. This position may cause difficulties in fixing the piece to a batten by means of a double hook when the batten is already furnished by a transverse edge of slate or flat tile. For this reason, the proximal wings of the soul of the piece are advantageously uneven relative to the plane of this soul as mentioned above. However, it is possible to provide, optionally, at least one relief, placed under the core of the part, capable, when laying this piece on a batten, to abut against the support face of this batten, usually a lower batt. This stop may be attached to the lower face of the core or, in a preferred embodiment, formed of a folded rim portion from a longitudinal edge of the core of the workpiece. On the other hand, this stop will be at least the same height as the thickness of the rod of the double hook.

According to another characteristic of the invention, each portion of folded longitudinal rim, comprising a distal gripping clamp, is located between two wings, one distal the other proximal.

These flange portions, each provided with a distal gripping pliers, have a length that corresponds substantially to the interval between two adjacent flats. Consequently, these distal portions of folded edges, associated with the distal tongs, provide the advantage, when positioned between two battens, of serving as a distance gauge between them and reinforcing elements for the soul of the room.

According to a further characteristic of the invention, the upper face of the core comprises a stamped portion, possibly traversed by integral relief lines possibly from splines made from the underside.

This stamped portion has the advantage of being able to drain a water which would have infiltrated under slates or flat roofing tiles, for example by capillarity or following bad weather notably due to a possible lack of tightness between two slates or tiles flat on both sides of a hook. For this reason, this stamped portion, which may represent a significant portion of the upper face of the core of the part, is positioned on either side of the longitudinal axis of this core and usually symmetrically with respect to this one.

On the other hand, the longitudinal edges of this stamped portion, which are derived from the proximal end of the core of the part, are parallel or substantially parallel to the longitudinal edges of this core, extend close to these and terminate at a transverse and distal edge also near the transverse edge of the distal end of the core of the workpiece. This transverse and distal edge of the stamped portion, is generally in the form of a circular arc including a semicircle although other forms may be adopted. By way of non-limiting example, this transverse and distal edge of the stamped portion may be rectilinear and parallel or substantially parallel to the transverse and distal edge of the core.

Thus, the embossed portion in question being open at the proximal end of the core of the workpiece therefore has no transverse and proximal edge there.

In addition, the possible grooves in question, made from the lower face of the core of the piece generate, on the side of the upper face, lines of relief or unevenness, generally rectilinear and parallel to the longitudinal edges of the soul , lines of relief whose height does not exceed the outcrop to the unembossed face of this soul. These lines of relief have the particular advantage of strengthening the strength of the soul of the room. If necessary, similar lines of relief can traverse the underside of the soul so as to further enhance the strength of the latter.

Incidentally, the upper face of the stamped portion may have a plurality of raised features, spaced and aligned. In this case, two line alignments of this type will be considered on both sides of the longitudinal axis of the core and in its distal zone. The space separating these two alignments will be substantially equivalent to the thickness of a hook with a point so that these raised features may advantageously serve as a guide when fixing such a hook.

According to another characteristic of the invention, the upper face of the core of the part is adorned with at least one sealing means.

This sealing means is advantageously arranged so as to slightly exceed the plane of the non-stamped face of the core and circumscribe, without a solution of continuity, the edges of the stamped portion. For this purpose this sealing means can be configured in different ways.

Thus according to a first embodiment, the sealing means may adorn the perpendicular or substantially perpendicular edges of the stamped portion and possibly extend to cover the most uneven surface of this stamped portion including the lines of relief that she can present. In another way, this sealing means may be limited only to an overlap of this most uneven surface possibly comprising the relief lines in question.

According to another embodiment, this sealing means can cover the unsworn portion of the upper face of the core, and possibly the edges of the stamped portion, or be limited to one or more fixed cover strips said upper face or be inserted in one or more grooves made from this upper face.

Advantageously, according to an additional and particularly advantageous feature of the invention, the sealing means completely covers the upper face of the core of the workpiece.

In this embodiment, the sealing means matches all the contours of this upper face.

Usually, this sealing means is made of a flexible material to semi-rigid, non-porous and waterproof, generally a synthetic polymeric material. Advantageously, this material will be selected from substances or compositions of substances capable of withstanding without major disadvantages temperatures ranging from -60 ° C to + 130 ° C.

This sealing means is generally in the form of a layer or film or a bead of such a flexible material to semi-rigid depending on whether the means respectively covers a surface or is housed in a groove. It is also possible to provide that this material, when it is placed on the non-stamped portion or on the projecting portion of the beads or on the tops of the stamped portion, is embellished with a series of asperities also produced in this manner. material.

When the upper face of the core of the part is covered only partially by a sealing means, the uncovered portions may themselves be coated with a layer of a protective means.

By way of example, this protective layer may be formed or comprise a layer of bitumen, tar, silicone or any materials or compositions of similar materials.

Moreover, when it is fixed on the upper face of the core, this sealing means is usually in the form of a sealing strip which extends in one piece, from the proximal end. of the soul, between the outer edges of the soul and the edges of the stamped portion. On the other hand, when inserted into a groove, this sealing means generally takes the form of a sealing bead.

According to a preferred embodiment, the thickness of the piece, at its upper end not stamped, is greater than at its lower end.

Accordingly, according to another characteristic of the invention, the unsworn portion of the core has, along its longitudinal edges, a substantially triangular profile or, preferably trapezoidal.

The invention will be better understood and other objects, features and advantages thereof will appear more clearly in the following explanatory description made with reference to the accompanying drawings given solely by way of examples illustrating various embodiments of the invention. the invention and in which:

• the figure 10 is a partial perspective view of the piece at the figure 9 ,
• the figure 11 is a plan view of an assembly of slates placed on pieces shown in Figures 7 to 10 .

As shown in figure 1 , the intermediate piece according to the invention comprises a core 1 which has longitudinal edges 1a and 1b and transverse edges, namely a transverse edge 1c at the distal part or end of the core and a transverse edge at the end proximal 1d thereof. The figure 1 also shows four portions of flanges, forming wings, from the longitudinal edges 1a and 1b. These wings are divided into a pair of wings 2 at the distal end of the core and in the extension of the transverse edge 1c and a pair of wings 3 positioned at the intermediate portion of this core and in relation to wings 2, as visible in figure 4 . This difference in height has the advantage of allowing easy attachment of the workpiece on battens despite the presence of slates or flat tiles placed under the portion A of recovery. On the other hand, each of these wings is provided with an orifice 4 for passage for example of a slate nail during attachment of the piece to the battens. Furthermore, the distal portion of the core shows, in its longitudinal axis Y, an orifice 5 intended for the passage for example of a hook with a point for attaching a slate to overlap a portion of the distal portion of the soul 1 of the room. As also represented figures 1 and 2 this core has a central portion 6 stamped whose edges are provided with a sealing bead 7 in one piece while the central portion of this stamped portion is occupied by lines of relief 8 obtained from grooves made on the underside of the soul of the room. On the other hand, as shown both figure 2 and the figure 4 , the wings 3 are uneven relative to the non-stamped portion 9 of the core of the piece.

In addition, figure 4 , that this unsworn portion of the core of the piece varies substantially linearly along its transverse edge 1a thus giving rise to a trapezoidal profile. This configuration makes it possible to gently soften the slope of a slate or flat tile partially overlapping two slates or flat tiles whose two adjacent edges overlap the soul 1 of the room.

We also notice, figures 9 and 10 , that the edge 1a of the piece is provided with a portion of longitudinal flange 10 folded at about 90 ° towards the lower face and positioned between the wings 2 and 3. When fixing the piece with two battens, as represented at figure 9 this flange portion is positioned between these two battens.

According to another embodiment at figure 5 , the upper face of the core 1 is completely coated with a seal 11 revealing, on the non-stamped portion, lines 12 of asperities of this seal. These lines of asperities, devoid of continuity solution, will crash when laying slates or flat tiles on the piece thus ensuring increased sealing.

Finally, we have represented figure 6 an assembly of slates 13 arranged in rows on parts according to the invention themselves fixed, through the orifices 4 to wooden battens 14 and 14a secured to rafters (not shown) of a roof.

So, we understand, referring to this figure 6 , that the piece according to the invention is first placed on the batten 14a through its distal zone comprising the wings 2 and on the adjacent batten 14 through its intermediate zone comprising the wings 3, this batten 14 being placed at a lower level than the batten 14a, guided in this by the portions of longitudinal flanges 10 which are interposed between these battens. After nailing, to the battens 14 and 14a, respectively of the distal part and the intermediate part of the piece and this, through the orifices 4, then fixing a hook tip 15 to the batten 14a through the l orifice 5, two slates 13 and 13a are placed on either side of the hook 15. The slate 13b is then placed, which will be held in place by the hook 15, the hook 15a, after being fastened to the hook 15. liteau 14b located at a higher level and the slate which will be positioned adjacent to this slate 13b.

According to another embodiment more particularly intended for a metal intermediate piece, the piece in the figure 7 , similar to that of the figure 1 , additionally comprises a double hook 16 secured to the core 1 by means of a distal clip 17 issuing from a folded longitudinal flange portion and a proximal clamp 18. The clip 17 is obtained by substantially shaped folding of S while the clamp 18 is formed by a curvature of a longitudinal flange portion in the direction of the underside of the core. This curved flange portion then undergoes a second curvature to create the uneven wing 3 in a lower plane than that of the wing 2 or the non-stamped portion 9, as visible in FIGS. Figures 2 and 4 .

In another way, and as represented in figure 8 , the distal clip 17 can also be produced from a folded longitudinal edge portion and this, by substantially U-shaped folding. The distal loop of the double hook 16 is thus brought to house the latter which is for example welded there to prevent possible disconnection during the attachment phase of the insert to a batten.

Similarly, according to another embodiment intended more particularly for an intermediate piece made of rigid synthetic polymeric material, the distal clip is derived from a portion 19 of flange 10, portion curved externally as shown in FIGS. figures 9 and 10 . This curved portion 19 is cut with a groove 20 forming a distal clamp while the wing 3 and its support foot 21, which form part with the portion 19, are themselves provided with a groove 22 forming a proximal clamp.

It is therefore understandable, and with reference to figure 11 , that the part according to the invention is first laid, via its intermediate zone on the batten 14, its distal zone being raised relative to the batten 14a, the clamps 17 being located between the batten 14 and 14a. By pulling on this piece, the clamps 17 are then brought to grip and firmly grip the batten 14 while the distal zone is rotated so as to join the batten 14a where it is fixed for example by nailing at the openings 4 and possibly in the orifice 5. In this operation the clip 17 advantageously plays the role of abutment preventing any separation between this clamp and the double hook 16 during traction. The slate 13 can then be placed on the intermediate piece and engaged in the proximal loop of the double hook 16.

The intermediate piece according to the invention has substantial advantages both in terms of sealing against water flowing over the roof covering or infiltrating by capillary action as well as resistance to leakage. wind, the anchoring strength or the speed of installation.

Thus, this piece can be used in connection with any shape and thickness of flat cover such as slate, flat tile or the like. Unlike the parts of the state of the art described above, the insert according to the invention can find use in connection with different types of roof reinforcement (battens, battens, rafters), for example a frame as well in wood as metal. On the other hand, the tightness it provides is perfect. In addition, this insert allows a roof covering installation three times faster compared to a traditional pose. Furthermore, the piece according to the invention can be fixed to battens by using any fixing means known to date in the field of roof covering, for example screws, nails hooks to nail or staple and this, through several anchor points.

The use of the piece according to the invention also allows a gain of at least 50% cover material since the overlap area of two slates or flat tiles can be reduced by half. As a corollary, this gain of slates or flat tiles ensures a reduction in the weight of the roof covering and, consequently, a reduction in the weight of structural accessories such as rafters, battens or battens. Considering the possibility of using three or even five anchoring points for its attachment, the piece according to the invention ensures high resistance to wind and weather including storms and heavy rains. Due to the particular configuration of this one, a contact between the slates or flat tiles of partial covering can be avoided, which makes it possible to ventilate the roof and to avoid an infiltration of water by capillarity as well as its consequences such as appearance of mosses and molds.

Finally, the piece according to the invention is completely invisible after its installation on battens even after minor adaptations for its application to banks left or right or valleys, for example after folding along its longitudinal axis at the desired angle.
