Description

INTERIOR PIECE FOR THE SUPPORT OF SLABS OR FLAT TILES

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

More specifically, the invention relates to an insert intended to be placed on adjacent battens of a roof, usually two adjacent battens, or cladding slats, usually two adjacent slats, so as to support flat means of recovery, including slates and / or flat tiles, positioned adjacent and to improve the tightness of the assembly thus formed, of the kind comprising an elongate core having: a) an upper face, optionally covered with ^one sealing means capable to support said covering means, as well as a lower face, this upper face being provided on the one hand with transverse edges located respectively at the distal and proximal ends of said core and on the other hand longitudinal edges, the latter comprising portions distal folded edges, b) at its distal end, two portions of non-folded longitudinal edges forming the distales •

Patent Application JP 04327635 describes an insert intended to support a means of covering a roof, the piece whose core comprises first a folded rim forming clamp for attachment to a first roof batting then longitudinal edge portions provided with notches for attachment to a second adjacent batt. The distal zone of this core is also provided with a hole cooperating with a hook for the retention of the covering means. On the other hand the soul in question is provided with a pair of wings at its distal end and a pair of wings at its proximal end.

Given the use of a clamp and notches as a means of attachment to a batten, this piece however has the disadvantage of use in relation only with particular configuration of battens including metal battens. In addition, the piece in question has a pair of proximal wings apparently without any particular utility.

Furthermore, EP 0710314 describes an intermediate piece intended for the support of slates or tiles, the corrugated core of which comprises portions of longitudinal edges provided with notches for attachment to a roof battens and of which 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 also has the disadvantage of use in relation only to 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, the patent application WO03 / 023164 discloses a part intended to support tiles on adjacent battens of a roof, the part of which the upper face comprises at least two sealing joints, one in the form of ^λ a bead inserted in a groove running along the longitudinal edges and a transverse edge of the workpiece, the other in the form of a transverse band overlapping the longitudinal axis of this workpiece. On the other hand, it is also provided with a transverse flange forming gripper 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 metal wire for attachment to 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. For this reason, this means must be manufactured expressly, which costs the cost. In addition, the securing means to the battens, provided in this patent application, prevents attachment to traditional wooden battens but requires metal battens with a particular profile.

The object of the present invention is to provide an intermediate piece capable of improving the attachment of slates and / or flat tiles to battens of a roof or slats for a cladding, this part being inexpensive and easy to manufacture. Modular and flexible to use since it can be considered in relation to wooden and metal battens, while offering a particularly effective sealing. To achieve this goal, the part of the type indicated above is characterized in that:

The transverse distal end edge does not have a folded rim forming a clamp and the proximal end of the core is devoid of wings derived therefrom,

On the other hand, according to another preferred embodiment of the invention:

The transverse distal end edge is devoid of a collapsed rim forming a clamp and the proximal end of the core is devoid of wings derived therefrom;

The transverse distal end edge possibly has a groove for guiding a means intended for fastening a covering means,

The distal wings and / or the distal end of the core are configured to join said part to a first batten or a first batten and possibly for a fastening of a covering means, and in that it comprises an assembly support on which are arranged: a) two proximal wings pierced possibly orifices for passage of a any means of attachment to a batten or slat, these wings being spaced from each other by a distance at least equal to the width of the core, b) retaining means of double hooks for hooking of said part to a second adjacent batt or to a second adjacent batten and hooking of covering means, c) as well as fastening means cooperating with retaining means arranged at the level of the distal portions of folded longitudinal flanges for a solidarization to this soul.

According to another particular characteristic of the invention of the invention, the distal and proximal wings as well as the distal end of the core each comprise an orifice for the passage of a fixing means as defined above, the edge transverse distal end has a guide groove as defined above and the proximal wings comprise retaining means for double hooks as defined above.

In the context of the present description as in the claims, the term "distal" will be used to designate a position of a configuration element or component of the part, namely the position farthest from the transverse end. of the soul which, when this soul is fixed to two adjacent battens uneven of a roof or two slats uneven of a cladding, is at a level higher than the second transverse end. Similarly, the term "proximal" will be used to designate a position of a configuration element or component of the part, namely the position closest to the transverse end of the soul which, when that soul is attached to two adjacent slabs of uneven roof or two adjacent slats uneven of a cladding, is at a lower level than the second transverse end. 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 'underside' means a face turned towards roof battens or cladding slats,

"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 may be made of any metal traditionally used in connection with roof reinforcement or lattice for cladding, for example preferably stainless steel, zinc, copper or a rigid synthetic polymeric material . I.- DISTAL WINGS AND PROXIMAL WINGS

The insert according to the invention preferably comprises four flanges grouped in pairs, each pair of flanges being intended to overlap a batten or batten for fixing thereto, namely a pair of distal flanges in the flange. distal zone of the soul and a pair of proximal wings in the middle zone of this soul. In addition, according to a further feature of the invention, the sum of the lengths of a distal wing and a proximal wing, determined along the longitudinal axis of the core, is less than the width of a batt or a batten to which they are attached.

Usually, the wings in question come from the spacer since they come from an extension of the plane of the upper face and the plane of the lower face of the soul. This configuration is particularly indicated in the case of distal wings. However, as indicated above, the proximal wings, for their part, can be derived from the soul of this piece or be removably attached.

Also, according to another characteristic of the invention, the insert comprises two distal wings whose lower faces are located in the plane of the lower face of the core and two proximal wings whose lower faces are uneven in a lower plane to lower faces of the distal wings.

So,

A. - in the case where the proximal wings are coming from the soul άe the intermediate part, a) their upper face is derived from the plane of the upper face of the soul while their lower face is uneven in a lower plane to the lower face of this soul and, consequently, in a lower plane to the lower face of the wings distal, or b) their upper face is uneven in a lower plane to the upper face of the soul while their lower face is uneven in a lower plane to the lower face of the soul and, consequently, in a lower plane to the underside of the distal wings.

In this second case, the proxitnal wings in question are totally uneven relative to the upper face of the soul and this, by means of support legs that ensure the junction to the soul. Each support foot comes, in general, a folded longitudinal flange of which an end portion curved outwardly to the workpiece forms the proximal wing proper. The proximal wing / support leg assembly usually takes an L-shaped configuration, that is to say at right angles.

B.- in the case where the proximal wingsε are removably attached to the insert at the core, these are advantageously arranged on an assembly support and spaced apart from each other. a distance at least equal to the width of the insert, the assembly support being configured to cooperate with said part to attach to it, as will be described in more detail later. In addition, the total height of these proximal wings will be such that their upper face, after fixation to the piece, will be positioned substantially in the plane of the upper face of the soul and their lower face will be advantageously uneven in a lower plane to the plane of the soul, accordingly in a lower plane to the lower faces of the distal wings.

The unevenness of the lower faces of the proximal wings with respect to the lower faces of the distal wings provided in the previous embodiments makes it possible, in particular, to soften the slope of the flat covering means when it is placed on the part according to the invention itself. fixed for example to battens of a roof uneven in opposite directions. Moreover, this unevenness of the proximal wings is particularly advantageous when this attachment of the part at its intermediate zone is achieved by means of traditional double hooks hook 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.

II.- FIXING AND HITCHING

The implementation of the insert according to the invention requires its attachment and / or possibly its attachment to the battens or slats, for example to perform a roof covering or cladding. According to a first embodiment, the part according to the invention is devoid of own means for its attachment or attachment to roof battens or slats for cladding. In this case, each distal wing is preferably pierced with at least one orifice, each proximal wing possibly having such an orifice. These orifices are intended for the passage of any means for fixing the intermediate part to roof battens or slats for cladding. This is usually a completely independent means of this piece, for example a screw, a slate nail or a hook tip.

Likewise, the core of this intermediate piece may also be pierced in its distal zone and substantially along its longitudinal axis or in the immediate vicinity of at least one orifice which allows the passage of a means suitable for the attachment of a covering means, for example a hook tip for hanging including 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 core which will be pierced and crushed during the passage of the attachment means thereby ensuring increased sealing.

According to another embodiment, the transverse distal end edge of the piece comprises a groove, for example profiled in a circular arc, in particular a semicircular groove, for guiding a fastening means to the batt or batten, for example a hook tip for hanging including a slate or a flat tile. This point hook, after fixing the piece to one of the two adjacent battens or to one of the two adjacent battens is itself fixed respectively to the batt or batten supporting the distal wings after embedding in the distal groove in question.

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 or slats and own means for the retention of these attachment means. These retaining means may be an integral part of this part, in the case in particular where the proximal wings are derived from or be attached thereto. In these different embodiments, the orifices provided at the wings may be present or absent.

Thus, according to another characteristic of the invention, the intermediate part is provided with means for attaching it to a batten or batten, means consisting of double hooks each comprising a rod provided, at its distal end, with a suitable buckle. to cooperate with a roof batten or a lath for cladding and, at its proximal end, a 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 piece, through a means that can take different forms depending in particular the material used for the realization of this piece.

Thus, according to a further characteristic of the invention, each double hook is secured to the intermediate piece:

a) when the proximal wings are issued from this piece, by means of retaining means, preferably in the form of tongs, these tongs coming from portions of folded or non-folded longitudinal edges of the core.

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. On the other hand, these distal and proximal clamps are located in the same plane.

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 retained retaining clip on the piece or, preferably, stemming from the soul of it.

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

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 hooking the lower batt of a pair of adjacent battens or the lower batt of a pair of adjacent battens is located under the plane of the underside of the batt. soul. Together, a second portion of the distal loop of the double hook, portion substantially parallel to the longitudinal axis of the core of the part and the lower face thereof, is also secured to a proximal retaining clamp reported on the piece or, preferably, resulting from it.

Usually, this proximal clamp is formed:

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.

b) a groove or groove made from the underside of a proximal wing 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, the insertion of the distal loop of the double hook in grooves or grooves can be reinforced by means of any additional means which may consist for example of a gluing 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 when hanging the piece to a batten or slat by means of a double hook when the batten or slat is already furnished with a transverse edge slate or flat tile. For this reason, the proximal wings of the core of the part are advantageously uneven by relation to the plan of this soul as mentioned above. However, it is possible to provide, optionally, at least one relief, placed under the core of the piece, able relief, when placing this piece on a batten or batten, to abut against the support face of this batten or batten, usually a lower batten or a lower batten. 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 retaining clip, is located between two wings, one distal to the other proximal.

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

b) when the proximal wings are, removably, attached to the insert, by means of retaining means, preferably in the form of clamps, these clamps coming from the assembly support, on which said proximal wings are arranged or reported. Thus, according to another characteristic of the invention, the proximal wings removably attached to said piece are disposed on an assembly support fixed to the core via the distal portions of folded longitudinal edges and are spaced apart. from each other by a distance at least equal to the width of the piece.

On the other hand, according to a further feature of the invention, the assembly support comprises means for retaining double hooks.

In addition, according to another characteristic of the invention, each means for retaining a double hook comprises a distal clamp substantially perpendicular to the upper face of the core of the workpiece and a proximal clamp substantially parallel to this upper face.

Thus, the distal and proximal clamps are perpendicular to the axis of the assembly support, perpendicular to each other and located in the same plane. Ordinarily, each distal clamp is represented by a groove in a support leg for the assembly support while the proximal clamp, also in the form of a groove, is made from the upper surface of the proximal wings or even from the underside of these. In the latter case, the distal and proximal clamps are in the extension of one another and merge into a single groove. In any case, the depth of the proximal groove made from the upper face of the core will be such that the stem of the double hook embedded in this groove will not exceed this upper face so as not to interfere with the installation of the means of recovery on the soul of the room. In addition, the assembly formed by the proximal wings disposed on the assembly support and by the retaining means of the double hook is provided, according to another characteristic of the invention, a means of solidarization of this support of assembly to said intermediate member itself is provided with a retaining means, generally disposed at the core, in particular at the folded longitudinal edges.

Usually, this securing means corresponds to arms optionally provided with an end stop. These arms, attached to the assembly support or from it, are arranged between the proximal wings.

Various embodiments of the securing means disposed on the assembly support and adapted to cooperate with retaining means at the core of the intermediate part may be envisaged. For example, the retaining means in question, usually arranged at the folded longitudinal edges of the core, corresponding for example to notches, orifices or portions themselves folded with folded longitudinal edges.

Thus, according to different implementations, each securing means represented by an arm of the assembly support can fit into a notch made in a folded longitudinal flange or be provided with one or more external lateral studs spaced apart from each other. others, one of these nipples coming to fit into an opening made in this folded longitudinal edge. In addition, each arm also has a "spacer" function. Indeed, a variation of the length of this arm from the assembly support to the retaining means at the core of the part, for example the notch or the orifice in the longitudinal flange, enables the proximal wing associated with this arm to vary in location along the longitudinal edge of the core and thus to modify the distance separating this proximal wing from the corresponding distal wing. According to another embodiment, each arm is placed and held, thanks to an end stop, on the upper face of a longitudinal flange portion and folded of the core of the workpiece, this folded edge being folded again. parallel to the lower face of the soul to give, ultimately, an L-shaped configuration. After folding, this parallel portion will be located or not under the soul of the piece. In each of these configurations, the upper face of the removable proximal wings and secured to the core of the intermediate piece will be substantially in the plane of the upper face of the soul.

According to another of its features, the invention relates to a module for fastening, to a roof battens or a lath for cladding, an intermediate part intended to support adjacent flat means of overlapping covering, characterized in it comprises an assembly support on which are arranged two wings possibly pierced orifices for the passage of a fastening means to a batten or batten, these wings being spaced apart from each other a distance at least equal to the width of said piece as well as retaining means for double hooks for attachment to a batten or slat and means adapted to cooperate with said part for a connection thereto.

In the light of the foregoing, it appears that the insert can be attached to a batten or batten of any kind, for example a batten or a batten of wood or metal, by means of various means taken in combination or separately and in particular:

by means, for example, of nails, screws or pointed hooks when the distal wings and / or the proximal wings are provided with orifices,

by means of, for example, pointed hooks or double hooks (hooks with hooks) when the web of the workpiece comprises a groove made along the distal transverse edge, by means, for example, of nails, screws or hooks with a point when the core of the part has an orifice preferably located in the longitudinal axis thereof,

by means of staple hooks when the proximal wings have a suitable configuration such as that described above.

III.- AME

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 because of a possible lack of sealing between two slates or tiles flat on both sides of a hook. For this reason, this stamped portion, which can represent a significant portion of the upper face of the soul of the piece, is positioned on either side of the longitudinal axis of this soul and usually symmetrically with respect thereto.

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 can 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 lines in relief, 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 a preferred embodiment, the thickness of the workpiece, at its unsplit upper end, 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.

IV.- SEALING

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 can adorn the perpendicular or substantially perpendicular edges of the stamped portion and possibly extend to cover the most uneven surface of the stamped portion including the lines of relief that she can present. In another way, this sealing means can be limited only to an overlap of this most uneven surface. possibly including 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 cover strips fixed to said same upper face or still 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.

Furthermore, whatever the embodiment adopted to ensure the seal in question, an additional sealing bead having a thickness at most slightly greater than that of the covering means can be fixed along the longitudinal axis of the seal. blade. This bead will also fulfill the guide function when laying two adjacent covering means on the insert. 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 chosen 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 to semi-rigid material depending on whether this 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 affixed to 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 it 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.

The intermediate piece according to the invention can be used for covering a flat surface such as a roof slope but also for covering angular surfaces such as left bank, right bank or valley of a roof.

Accordingly, according to another feature of the invention, the insert is folded along its longitudinal axis, at an appropriate angle, for use at a right bank, a left bank or a valley. of a roof. 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:

As represented in FIG. 1, the intermediate piece according to the invention comprises a core 1 which has longitudinal edges 1a and 1b as well as transverse edges, namely a transverse edge 1c at the distal part or end of the core and a transverse edge at the proximal portion or end Id thereof. FIG. 1 also shows four flange-like flange portions originating from the longitudinal edges 1a and 1b. These flanges are distributed in a pair of flanges 2 at the distal end of the core and in the extension of the transverse edge Ic and a pair of wings 3 positioned at the intermediate portion of this soul and in level with respect to the wings 2, as visible at Figure 4. This difference in elevation has the advantage of allowing easy attachment of the piece on the battens despite the presence of slates or flat tiles placed under the portion A covering. 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 shown in Figures 1 and 2, this core has a central portion 6 stamped whose edges are provided with a bead 7 sealing 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 piece. On the other hand, as shown both in Figure 2 and Figure 4, the wings 3 are uneven relative to the non-stamped portion 9 of the core of the piece.

It is further observed in Figure 4, that this unsplit portion of the core of the part varies substantially linearly along its transverse edge 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.

It will also be noted in FIGS. 9 and 10 that the edge la of the part is provided with a portion of longitudinal flange 10 folded at approximately 90 ° in the direction of the underside and situated between the flanges 2 and 3. fixing of the piece with two battens, as shown in Figure 9, this rim portion is positioned between these two battens.

According to another embodiment in FIG. 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, there is shown in Figure 6 a slate assembly 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.

Thus, it will be understood, with reference to this FIG. 6, that the part 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 by way of its intermediate zone comprising the flanges 3, this batten 14 being placed at a lower level than that of the batten 14a, guided thereby by the longitudinal flange portions 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 is held in place by the hook 15, the hook 15a, after it has been fastened to the slat 14b located at a higher level and by the slate that will be positioned adjacent to this slate 13b. According to another embodiment more particularly intended for a metal insert, the part in FIG. 7, similar to that of FIG. 1, additionally comprises a double hook 16 secured to the core 1 by means of a clamp. distal 17 from a portion of folded longitudinal flange and a proximal clamp 18. The clamp 17 is obtained by substantially S-shaped folding while the clamp 18 is made by a curvature, a longitudinal flange portion, in the direction of the lower face of the soul. This portion of curved flange then undergoes a second curvature to create the wing 3 uneven in a lower plane than that of the wing 2 or the non-stamped portion 9, as visible in Figures 2 and 4.

In another way, and as shown in FIG. 8, the distal clip 17 can also be made from a folded longitudinal edge portion by substantially U-shaped folding. The distal loop of the double hook 16 is thus brought to accommodate the latter which is for example welded therein to prevent possible disconnection during the attachment phase of the insert to a batteau.

Similarly, according to another embodiment intended more particularly for an intermediate piece made of rigid synthetic polymeric material, the distal clamp is derived from a portion 19 or end section 10 of flange, portion bent outwardly as shown in Figures 9 and 10 This curved portion 19 is cut with a groove 20 forming a distal clamp while the flange 3, which is integral with the portion 19, is itself provided with a groove 21 forming a proximal clamp. It is therefore understood, and with reference to FIG. 11, that the part according to the invention is firstly placed via its intermediate zone on the batten 14, its distal zone being raised relative to the batten 14a, the tongs 17 being located between the battens 14 and 14a. By pulling on this piece, the distal loops of the double hooks 16 are then brought to grip and firmly grip the batten 14 while the distal zone of the core of the part is rotated so as to join the batten 14a where it is fixed for example by nailing at the openings 4 and possibly at the orifice 5. In this operation the clamp 17 advantageously plays the role of stop preventing any separation between the clamp and the double hook 16 during the pulling. The slate 13 can then be placed on the intermediate piece and engaged in the proximal loop of the double hook 16.

In FIGS. 1 to 11, the embodiments of the part according to the invention show proximal wings 3 arranged fixed at the level of the core 1 since they emerge entirely from the latter.

According to another embodiment in FIG. 12, the intermediate piece 22 is provided with distal wings 2 located in the non-visible portion. There is distinguished the upper face 23 of the core, a pressed portion 24 thereof, a peripheral sealing bead 25 and a sealing strip 26 running along the longitudinal axis of the workpiece. This piece 22 is, however, devoid of wings at the intermediate portion of the core. On the other hand, the rim 10 has, at its own transverse edge, a notch 27 intended to receive a module 28, represented in FIG. 13. This module 28 comprises an assembly support 29 on which the wings 3 are arranged. from these support, these wings ensuring the function of proximal wings in the intermediate zone of the soul in Figure 12. These wings 3 are spaced from each other by at least the width of the soul of the piece 22 and reveal a groove 30 made from their upper face. This groove 30 serves to allow the passage, if necessary, the rod of a hook tip, the depth of this groove at least equivalent to the thickness of this rod to ensure easy installation of a recovery means on the soul of the room. This FIG. 13 also shows, for each wing, a proximal clamp 31 and a distal clamp 32 in the form of both grooves in which will be embedded a double hook 16 (not shown), as well as a arm 33 which, when the module 28 is joined to the intermediate piece 22 in FIG. 12, will fit into the notch 27. This distal clamp is made in a support leg for the assembly support 29 whereas the proximal clamp is made so that its depth is at least equivalent to the thickness of the stem of a double hook.

Depending on the depth of insertion of the arms 33 in the notches 27, the position of the wings 3 of the module 28 may vary along the part 22 so as to change, if necessary, 1 'spacing between the distal wings 2 and the wings 3 proximal according to the distance between two adjacent battens to which the module 28 secured to the piece 22 must be fixed.

As will also be seen in FIG. 12, the flange 10 of the piece 22 also shows an opening 34. This opening is intended for another embodiment of the arms 33 of the module 28. According to this alternative embodiment, these arms 33 are provided on their outer longitudinal edges, that is to say on their edges not facing one another, nipples capable of snapping into these openings 34.

According to another embodiment in FIGS. 14, 16 and 17, the module 28 comprises an assembly support 29, wings 3 as well as arms 33 provided with a flange 35. FIG. 17, which illustrates the lower face of FIG. this module further shows that the proximal and distal clamps 31 are located in the extension of one another and merge into a single clamp. Such a module may be secured to the core 1 of an intermediate piece which comprises, as a retaining means, a folded longitudinal edge portion 10 as shown in FIG. 15. This portion, itself folded to give a configuration final L-shaped form a support 36. When joining the module to the core of the insert, as shown in Figure 14, the arm 33 is placed on the support 36 and is maintained thanks on the one hand to the assembly support 29 in abutment against the flange 10 and secondly the flange 35 itself abuts against the edge of the support 36

According to an alternative embodiment of the part in Figure 15, the support 36 consists of a flange portion 10 folded under the core 1 of this piece.

The intermediate part according to the invention has substantial advantages both in terms of sealing against the water which is allowed to flow over the roofing or to infiltrate 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 pieces of the state of the art described above, the intermediate part according to the invention can find use in connection with different types of roof reinforcement (battens, battens, rafters), for example a frame of both wood and metal. On the other hand, the sealing it provides is perfect. In addition, this insert allows a roof covering installation three times faster compared to a traditional pose. Furthermore, the part according to the invention can be fixed to battens by implementing any fastening means known to date in the field of roof covering, for example screws, nails, hooks to be nailed or stapled and this , via several anchor points. In addition, according to a particular embodiment, the part according to the invention has a modular configuration in that the distance separating the distal wings of the proximal wings can be adapted according to the distance separating two adjacent battens or adjacent slats to which this part must be fixed. 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. Because of 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 prevent water infiltration by capillarity and its consequences such as the appearance of moss and mold.

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