The prefabricated element is also fixed on a support structure by means o the ribs of ~he internal face.
The general aim of the invention is to make full use of the advantages offered by the design concept outlined in the foregoing~ These advantages are mainly as follows :
- an ascending circulation of air beneath the roof of a housing structure, thereby eliminating condensation phenomena and achieviny enhanced thermal comfort within
-2-e~
the occupied enclosure of said housing structuxe ;
- connections and attachments provlded or the prefabricated elements and ~er~tting various degrees o~ freedom for accommodating relative expansions ;
- a system o~ connection provided between the prefabricated elements and so designed as to permlt draining of rain water both longitudlnally ~Id transve.rsely , - the bearing points on the support structure are chosen independently of the spacing of imi~ated relief patterns on the external face of the prefabricated elementO
According to the present invention, it is sought in particular to achieve an even more de5irable objective/
namely that of preventing any formation of moisture beneath the internal face of the wall constituted by prefabricated elements. This result is obtained not only by permitting free circulation of ascending air but by ensuring in addition tha~ streamlng rainwater i5 drained-off at the periphery of the prefabricated element.
With this objective, the prefabricated element according to the invention and designa~ed hereinafter as an '`element" is distinguished by the fact that the ends of said element considered in opposite pairs are provided with structural sections of complementary shap~ which are trans-verse and parallel to the ribs and which are intended to interengage in order to couple said element with other adjacent elements. Two of said end sections are placed 9 ~ ~
consecutively on tha periphery of the element and are formed in the wall of sald element by a depression having a U-shaped cross-section which is open on ~he side corr~
sponding to the ex~ernal face. Said two end sections are so arranged that the U-shaped depression of one end section communicates with ~he U-shapecl depression of the other end section at the junction between the two and in particular at the top corner of an element which is in position.
The re~ult thereby achieved ls that any streamlng rainwater which may in~iltrate between the assemblles of interengag~d elements is recovered transversely and then collected in the longitudinal direction down ~o the base of the panel by virtue of the communicating U-section depressions. When streaming of rainwa~er stops, a circula-tion of air replaces the rainwater and performs acontributory role in drying the internal face of the panel and any wet mud which may have formed on the joints of the elements together with atmospheric dust particles.
Moreover, water-tigh~ness of the transverse 20 a~sembl~ is enhanced by completing the interlocking action by means of an engagement in the plane and within the ; thickness of the wall of the element. This provides the additional advan~age of making the elements indissociable, particularly in the presence of wind. This assembly by lateral engageme~t is so arranged that coupling of elemen~s ; takes place withi.n the transverse U-shaped drainage channel, 9 ~ ~
thus ensuring that any water whlch might otherwise seep through the assembly ~oint i~ collected in all cases.
To this end, the element is provided with m~ans for assembling two elements in side-by-side relation by 5 means of the ends which aIe transverse to ~he ribs. Said mean~ are provided by interengagem2nt of complementary structural sections and especially arrises fitted within a depression having a U-shaped cross-section. The means aforesaid are completed by the engagement, substantially in the direction of the plane of the element, of a tong~le within a groove which opens into said U-section ~ransverse depression on that arm of the U which is placed on the inside of the element.
Furthermore, the existence of ribs has made it possible to devise a simple system for attaching the element in accordance with the invention to the support structure. Fastening members are advantageously provided within the thickness of the rib and capable of cooperating with rigidly fixed members of the support structure in order to lock said element in position.
In a preferred bu~ non-limitative embodiment, metallic nuts are included in the webs of the ribs. In this case, the element is rigidly fixed to the support structure hy means of threaded rods screwed into the nuts on the side corresponding to the in~ernal face. This type of fastenlng retains the advantage of the invention as dlsclosed in the main patent by making it posslble to select the spacing of the ~earing points on the support structure independently of thP pitch of the patterns form~d in relief or the attractive appearance of the external face of the element. To thi5 end, at least two ribs o~ the element are provided locally with a fastening member and especially a nut which is included in the web of the rib and emerges on its arris. Said fastening member is adapted to engage on another fastening member and especially a threaded rod rigidly fixed to the support structure for locking the element in position.
In a preferred alternative embodiment, the element can be retained by clamping a lateral edge against the support structure by means of a bracket rigidly fixed to said structure. Clamping by simply applying the element against the structure provides the degrees of reedom which are necessary for accommodating relative expansionsO The aforementioned clamping bracke~ will advantageously be mounted on a complementary transverse sectional member which will be so designed as to integrate and then complete ly mask the clamplng bracket behind the external surfaces of the assembled elements.
With this end in view, the element comprise5 complementary sectional members for transverse assembly 25 which serve to lock the element in posi~ion by clamping the outer arm of the U o the transverse depression against the ~ ~ 8 ~
support structure by means of the free arm of a right~
angled bracket which is rigldly fixed to said support structure.
It is assumed that the prefabricated element according to the invention is designed for the construction of roo.fing panels for houses but this application ls con-sidered only by way of example and not in any sense by way of limi~ation. The fastening system is so arranged that a gap is left between the two elements located at the ridge 10 of the roof. It is therefore necessary to fill and seal this gap. Accordingly, the ridge member is constituted by an L-section member which covers the top ends of the roof panels and is provided on the internal face of each of its ~langes with a sectional member or locking the ridge elements in position by engagement within a complementary sectional member which is rigidly fixad to each free edge of the panels.
These and other features of the invention will be more apparent to those skilled in the art upon consid~ration 20 of the following description and accompanying drawings, wherein :
- Fig. 1 is a part-sectional view in perspective showlng a covering panel according to the inventlon ;
- Fig. 2 is a side view of two assembled elem~n~s ;
- Fig. 3 is an end view showlr.g the assembly of two consecut:ive panels;
9 ~ 7 - Fiq. 4 is a view in perspec~ive showing the maans adopted for clamping an element on the support 5 tructure ;
- Fig. 5 is a schematic diagram of a ridge 5 element according to ~le invention.
In the ex~mple described hereinafter and illus trated in the accompanying drawings, it ~ill be postulated that the prefabricated element accordlng to the invention is designed for the construction of rooflng panels for houses. It will be understood, however, that this applica-tion is not given in any limiting sense.
Accordingly~ it should first be mentioned with reference to Fig. 1 that the ridge of the roof is located at the top of the figure and that the bottom edge of the roof is located at the bottom of the figure.
In the example shown, the prefabricated element is generally designated by the reference numeral 1 and has a square or substantially rectangular shape. Said pre-fabxicated element is molded in one piece from synthetic material which may or may no~ be reinforced and comprises a thln wall 2 having a thickness of a few millimeters. The vislble external face 3 of said thin wall has a special decorative appearance which imitates a series of overlapping slates in the example which is illustrated in the figure.
The reference numeral 5 desi~lates shoulders which consti~-ute the visible edges of the slates. F-ur~hermore, alt~r-~8--nate grooves 4 are ~ormed ln the external face 3 in thedirection of slope of the roof in order to complete th~
imitation~
Starting from the internal face 6 of the wall 2, provision is made for a series of parallel ribs 7 which extend in the direction of slope of the roof. The ribs 9a and 9c form the opposlte lateral edge~ of the elem nt whllst the ribs 7 designate the intermediate ribs. Said ribs are preferably formed opposite to grooves 4, with the result that the local reduction ln strength resulting from said grooves is compensated to a substantial extent by the over-thickness of the ribs 7.
At the top end of the element 1 which is intended to be mounted near the ridge of the roof, provision is made for a structural ~ection formed by a depression 12 having the shape of a ~ which is open towards the exterior. Said depression 12 has two partitions lO and ll which are sub-stantially perpendicular to the wall 2. A groove 17 which is substantially parallel to the wall 2 opens into the 20 partitio~ 10 of the depression 12. Said groove 17 is intended to xeceive the tongue 16 of the complementary structural section of the o~her transverse end portion.
The d~pression 12 communicates with the depression 15 of the lateral sectlon of the element, This communication is established by means of the opening or passageway 21.
Ra:Lnwater which is drained-off within the g ~ '~
depression 12 is collected in the depr~ession 15 at~r passing through the openirlg 21 and is finally discharged at the base of the roof panel.
At the bottom end of the element 1, provision is made for a structural section formed by a partition 8 which is substantially perpendicular to thQ wall ~ and for a tongue 16 which is substantially parallel to the surface of the element. Said partition 8 i5 intended to be applied again~t the complementary partition 10 whilst the tongue 16 engages wi~hin the groove 17 of a transverse end portlon of another element.
As shown particularly in Figs. 1 and 2, the elements complete each other in a wholly satisfactory manner after they have been placed in position and the drainage depression 12 is masked by the wall 2. The other partition 11 of the depression 12 is adapted to engage within a recess 23 of the ribs 7 and more particularly within the notch 22. In anothex form of construction, the partition 11 could be fitted agains~ a complementary partition on the underface of the element, thus coupling the bottom ends of the ribs.
The assembly of elements in the longitudinal direction of the roof i~ shown in Fig. 3. It is apparent that this assembly is carried into practical effect by engagement of two lateral end ribs 9a and 9b forming the arms o a U over the partitions 13 and 14 of the depression 15. The special ribs 9a and 9b as well a~ the partitions 13 and 14 are all substantially perpendicular to the wall 2. After side-by-side interengagemen~ of two elements, the depression 15 is completely masked by the wall 2. In order to ensure that one element is correctly positioned with respect to the other, lugs 18 placed between the rib 9c and the partition 13 at uniform inter~als are adapted to engage wi~lln the recesses 19 ~ormed in the rib 9a, the shape of said recesses being compl.em0n~ary ~o the lugs.
~he method adopted for attaching the elements to tha support structure L will now be described. This attach-rnent is shown,in Fig. 4, in which an element 1 is clamped against a wall plate L of the support structure by means of the right-angled bracket 24 which is rigidly fixed to said wall plate by means of the fastening device 25.
The arm of the clamping bracket 24 maintains the element 1 against the wall plate by bearing on the partition 11 of the end structural section. It is apparent that the thickness of said bracket arm and the height of the partition 11 must be such that, when they are placed one above the other at the time of clamping, the adjacent element is permitted to engage within the groove I7 and ovsr the partition 11. This attachment becomes invisible aftar assemhly of the elements which form the roof panel and permits slight displacemen~s in a parallel or trans-verse direction with respect to the ribs. The presence of 9 ~ PJ
ribs 7 benea~h the U-shaped depression 12 ensure~
continuity of the longitudinal Eree spaGes and free cir-culation of ascending air beneath the wall of the element.
If ~he s~lpport struc:ture is provided in the form 5 of a continuous flat surface, the clamping bracket 24 lg modified while retaining the s~me method of attachment.
The new bracket i5 accordingly provided in the form of a do~le S shaped bracket, one arm of which is adapted to clamp the partition 11 as before whilst the other arm, which is substantially parallel to the first, i5 applied against and fixed on the flat structure.
The two standard elements 1 of the invention which are located at the ridge of the roof are placed in spaced relation so as to form an intermediate gap. Pro-v~sion is therefore made for a ridge element which, as shownin Fig. 5, can be constituted by an L-section member 26 which is intended to cover the two end elements. The L-section member 26 is fixed in position by making use of an intermediate locking member 28 which is designed in the form of a structural shape. The groove 29 of said locking member is adapted to fit over the wall 2 of the element.
The locking member is rigidly fixed to the element by fitting a rivet 31 which serves to couple the wall 2 to the member 28.
A sectional member 30, one edge of which is rigldly fixed to or integral with the locking member 28, forms a deep groove on the surfac~ o said locking member.
The two upper end elements of the roof are equipped with said locking member 28. The two tongues 27 provided on the internal surface of the flanges of the L-section member 26 are then inserted in the g:roove~ formed on the locking members 28. The ridge element i5 thus rl.gidly fixed to ~he roof covering. It will be noted that fixing o the L-section member 26 on the ridgle can be effected simply by sliding said member along the arris of the roof.
At the level of the ridge 26, ventilation is ensured by lateral escape of air at the ends of the roof, thus maklng it possible to dispense with all types of ventilating systems.

These and other features of the invention will be more apparent to those skilled in the art upon consid~ration 20 of the following description and accompanying drawings, wherein :
- Fig. 1 is a part-sectional view in perspective showlng a covering panel according to the inventlon ;
- Fig. 2 is a side view of two assembled elem~n~s ;

9 ~ 7 - Fiq. 4 is a view in perspec~ive showing the maans adopted for clamping an element on the support 5 tructure ;
- Fig. 5 is a schematic diagram of a ridge 5 element according to ~le invention.
In the ex~mple described hereinafter and illus trated in the accompanying drawings, it ~ill be postulated that the prefabricated element accordlng to the invention is designed for the construction of rooflng panels for houses. It will be understood, however, that this applica-tion is not given in any limiting sense.
Accordingly~ it should first be mentioned with reference to Fig. 1 that the ridge of the roof is located at the top of the figure and that the bottom edge of the roof is located at the bottom of the figure.
In the example shown, the prefabricated element is generally designated by the reference numeral 1 and has a square or substantially rectangular shape. Said pre-fabxicated element is molded in one piece from synthetic material which may or may no~ be reinforced and comprises a thln wall 2 having a thickness of a few millimeters. The vislble external face 3 of said thin wall has a special decorative appearance which imitates a series of overlapping slates in the example which is illustrated in the figure.
The reference numeral 5 desi~lates shoulders which consti~-ute the visible edges of the slates. F-ur~hermore, alt~r-~8--nate grooves 4 are ~ormed ln the external face 3 in thedirection of slope of the roof in order to complete th~
imitation~
Starting from the internal face 6 of the wall 2, provision is made for a series of parallel ribs 7 which extend in the direction of slope of the roof. The ribs 9a and 9c form the opposlte lateral edge~ of the elem nt whllst the ribs 7 designate the intermediate ribs. Said ribs are preferably formed opposite to grooves 4, with the result that the local reduction ln strength resulting from said grooves is compensated to a substantial extent by the over-thickness of the ribs 7.
At the top end of the element 1 which is intended to be mounted near the ridge of the roof, provision is made for a structural ~ection formed by a depression 12 having the shape of a ~ which is open towards the exterior. Said depression 12 has two partitions lO and ll which are sub-stantially perpendicular to the wall 2. A groove 17 which is substantially parallel to the wall 2 opens into the 20 partitio~ 10 of the depression 12. Said groove 17 is intended to xeceive the tongue 16 of the complementary structural section of the o~her transverse end portion.
The d~pression 12 communicates with the depression 15 of the lateral sectlon of the element, This communication is established by means of the opening or passageway 21.
Ra:Lnwater which is drained-off within the g ~ '~
depression 12 is collected in the depr~ession 15 at~r passing through the openirlg 21 and is finally discharged at the base of the roof panel.
At the bottom end of the element 1, provision is made for a structural section formed by a partition 8 which is substantially perpendicular to thQ wall ~ and for a tongue 16 which is substantially parallel to the surface of the element. Said partition 8 i5 intended to be applied again~t the complementary partition 10 whilst the tongue 16 engages wi~hin the groove 17 of a transverse end portlon of another element.
As shown particularly in Figs. 1 and 2, the elements complete each other in a wholly satisfactory manner after they have been placed in position and the drainage depression 12 is masked by the wall 2. The other partition 11 of the depression 12 is adapted to engage within a recess 23 of the ribs 7 and more particularly within the notch 22. In anothex form of construction, the partition 11 could be fitted agains~ a complementary partition on the underface of the element, thus coupling the bottom ends of the ribs.
The assembly of elements in the longitudinal direction of the roof i~ shown in Fig. 3. It is apparent that this assembly is carried into practical effect by engagement of two lateral end ribs 9a and 9b forming the arms o a U over the partitions 13 and 14 of the depression 15. The special ribs 9a and 9b as well a~ the partitions 13 and 14 are all substantially perpendicular to the wall 2. After side-by-side interengagemen~ of two elements, the depression 15 is completely masked by the wall 2. In order to ensure that one element is correctly positioned with respect to the other, lugs 18 placed between the rib 9c and the partition 13 at uniform inter~als are adapted to engage wi~lln the recesses 19 ~ormed in the rib 9a, the shape of said recesses being compl.em0n~ary ~o the lugs.
~he method adopted for attaching the elements to tha support structure L will now be described. This attach-rnent is shown,in Fig. 4, in which an element 1 is clamped against a wall plate L of the support structure by means of the right-angled bracket 24 which is rigidly fixed to said wall plate by means of the fastening device 25.
The arm of the clamping bracket 24 maintains the element 1 against the wall plate by bearing on the partition 11 of the end structural section. It is apparent that the thickness of said bracket arm and the height of the partition 11 must be such that, when they are placed one above the other at the time of clamping, the adjacent element is permitted to engage within the groove I7 and ovsr the partition 11. This attachment becomes invisible aftar assemhly of the elements which form the roof panel and permits slight displacemen~s in a parallel or trans-verse direction with respect to the ribs. The presence of 9 ~ PJ
ribs 7 benea~h the U-shaped depression 12 ensure~
continuity of the longitudinal Eree spaGes and free cir-culation of ascending air beneath the wall of the element.
If ~he s~lpport struc:ture is provided in the form 5 of a continuous flat surface, the clamping bracket 24 lg modified while retaining the s~me method of attachment.
The new bracket i5 accordingly provided in the form of a do~le S shaped bracket, one arm of which is adapted to clamp the partition 11 as before whilst the other arm, which is substantially parallel to the first, i5 applied against and fixed on the flat structure.
The two standard elements 1 of the invention which are located at the ridge of the roof are placed in spaced relation so as to form an intermediate gap. Pro-v~sion is therefore made for a ridge element which, as shownin Fig. 5, can be constituted by an L-section member 26 which is intended to cover the two end elements. The L-section member 26 is fixed in position by making use of an intermediate locking member 28 which is designed in the form of a structural shape. The groove 29 of said locking member is adapted to fit over the wall 2 of the element.
The locking member is rigidly fixed to the element by fitting a rivet 31 which serves to couple the wall 2 to the member 28.
A sectional member 30, one edge of which is rigldly fixed to or integral with the locking member 28, forms a deep groove on the surfac~ o said locking member.
The two upper end elements of the roof are equipped with said locking member 28. The two tongues 27 provided on the internal surface of the flanges of the L-section member 26 are then inserted in the g:roove~ formed on the locking members 28. The ridge element i5 thus rl.gidly fixed to ~he roof covering. It will be noted that fixing o the L-section member 26 on the ridgle can be effected simply by sliding said member along the arris of the roof.
At the level of the ridge 26, ventilation is ensured by lateral escape of air at the ends of the roof, thus maklng it possible to dispense with all types of ventilating systems.

A prefabricated element for the construction of covering panels, comprising a substantially flat wall, one face of which is intended to be placed at the exterior and is provided with a decorative relief pattern which may imitate the appearance of traditional covering materials, the internal face of said flat wall being provided with substantially parallel stiffening ribs which are oriented longitudinally along the line of greatest slope of the pre-fabricated element and alone bear on the support structure, thus delimiting free spaces between the aforesaid wall and the support structure along the longitudinal dimension of the panel formed by the assembly of prefabricated elements, means for joining each element to other identical elements placed in side-by-side relation, and means for fixing each element to a stationary support structure, wherein the ends or each element considered in opposite pairs are provided with structural sections of complementary shape which are transverse and parallel to the ribs and which are intended to interengage in order to couple said element with other adjacent elements, two of said end sections being placed consecutively on the periphery of the element and formed in the wall of said element by a depression having a U-shaped cross-section which is open on the side corresponding to the external face, said two end sections being so arranged that the U-shaped depression of one end section communicates with the U-shaped depression of the other end section at the junction between the two and in particular at the top corner of an element which is in position.
2. A prefabricated element according to claim 1, comprising means for assembling two elements in side-by-side relation by means of the ends which are transverse to the ribs, said means being provided by interengagement of com-plementary structural sections and especially arrises fitted within a depression having a U shaped cross-section and being completed by the engagement, substantially in the direction of the plane of the element, of a tongue within a groove occupying each transverse end of the element, wherein the groove which receives said tongue opens into the U-section transverse depression on the arm of the U which is placed on the inside of said element.
3. A prefabricated element according to claim 1 or claim 2, wherein at least two ribs of said element are pro-vided locally with a fastening member and especially a nut which is included in the web of said rib and emerges on its arris, said fastening member being adapted to engage on another fastening member and especially a threaded rod rigidly fixed to the support structure for locking said element in position.
4. A prefabricated element according to claim 1, wherein the complementary sectional members for transverse assembly serve to lock the element in position by clamping the outer arm of the U of the transverse depression against the support structure by means of the free arm of a right-angled bracket which is rigidly fixed to said support structure.
5. A roof for a building and constituted by an assembly of prefabricated elements according to claim 1, wherein the ridge of said roof is constituted by an L-section member which covers the top ends of the roof panels and is provided on the internal face of each of its flanges with a sectional member for locking the ridge elements in position by engagement within a complementary sectional member which is rigidly fixed to each free edge of said panels.
