14 Claims. (01. 10813) The framework of the roof, in the embodiments hereinafter described, includes ratters 2 supporting transverse purlins 3.

This framework is covered with a plurality of elements 4 called, in the present description, tiles although they diiier in many points from conventional tiles.

As already described in my prior patent above referred to, these tiles are disposed to make each an angle (preferably approximately the same for all of them) with the general direction of rafters so that the whole constitutes a succession of steps. Each step corresponds to the interval between two successive purlins 3 and fixation means 5 (for instance nails or screws) extendmg in a direction substantially parallel to the general slope of the roof secure the tiles to the framework (for instance to the lower side wall of purlins 3).

For this purpose, each tile is advantageously made of rectangular shape, with. upper and lower sides bent at right angles, one downwardly and the other upwardly, to form flanges l and 4 The upper flange 4" of a tile is applied against the lower side wall of a purlin and is covered by the lower flange 4 of the tile located immediately above.

Such tiles may be made of any suitable material, such as clay, fibre-cement, etc., but preferably, for roofings of tropical buildings, they are made of sheet metal, the main portion of the tile being preferably plane.

According to a feature of the present invention, each tile, made, in a general manner, as

above described, is provided with lateral. upward With such an arrangement, supposing that two adjacent tiles are separated from each other by a rod it supported by purlins 3, the flanges 4a of the two respective tiles applied against the sides of said rod It will be covered by means of an arch-shaped cover ll adapted to span the whole of rod i6 and said two flanges la.

Advantageously, each cover ll includes, in addition to its lateral flanges Ila, a lower flange H" and an upper flange ll.

Lateral flanges Ila are advantageously of a height corresponding substantially to that of rods l6 and flanges l'l and I7 are made of a height approximately equal to the sum of the heights of a purlin 3 and a rod IS, the flanges 4 and 4 of tiles 4 being then made of a height corresponding to that of a purlin 3 whereas their i flanges ia are made of a height corresponding to that of said rods l6.

It is pointed out that, in order to facilitate transportation and storing of the tiles, the flanges of said tiles may be bent at an obtuse angle to the main part thereof, as shown by Fig. 3.

In this case, of course, rods l6 and covers il' will be made of trapezoidal section.

With an arrangement as above described, the tiles, fixed on their four sides on the framework, are assembled in a perfectly watertight manner. At every point of its outline, each tile is protected against rain or wind infiltration since, along its lateral sides, it is covered by a cover ll, at the top it is covered by the overlapping lower flange of the tile located above it, whereas, at the bottom it is bent downwardly to cover the upper flange of the tile located under it.

This structure does not include any part driven perpendicularly to the general surface of the roof and therefore no infiltration can take place at the points of fixation.

On the other hand, as the tiles are each fixed along its four sides, it is possible to make use of longer tiles which involves a reduction of the costs for covering a given area. Finally, due to their lateral fixation on rods it, the tiles are less liable to vibrations of the kind of those which may occur when a violent wind is acting on an ordinary sheet metal roof covering.

Concerning the connection of the covering with the ridge-piece, it will be effected in the same manner as described in my above mentioned prior patent application, i. e. by providing, if necessary, between the lower flanges oi the tiles of the last row at the top and the purlin located immediately below the ridge-piece, a thickness piece capable of compensating for the excess of length of said tiles with respect to the height of the strip that remains to be covered.

. As for the covering of the width of a roof slope, it will suflice, if this width does not constitute a true multiple of the width of the tiles,

to reduce the width of the tile resting on the ridge piece (if such a piece exists) and then to form a new flange on this side of the tile.

In the particular case of roof surfaces of trapezoidal or triangular shape, the angle tiles must 'be cut to fit on the ridge pieces, suitable flanges being formed along the edges thus cut.

Figs. 4 to '7 are sectional views intended to illustrate the above stated features.

' It has been supposed, in the preceding description, that the tiles were intended to be secured to a wood framework, but, according to my invention, these tiles can be used in the same manner in the case of a metallic framework in which 'l'i so that the flanges Ila thereof are applied against the outer faces of said irons ifla.

If the rod is constituted by a single angle iron 55a, as illustrated by Fig. 10, I may associate with 'said element a wood rod i6 about which is fitted cover ll, transverse tie-rods [8 being advantageously provided to keep the various elements of the assembly tightly applied against one another.

If the rod is constituted by an inverted T iron,

as shown by Fig. 11, the lateral flanges 4a of the tiles may be applied against the respective sides of the vertical portion of said iron i'ta, the three thicknesses of metal thus juxtaposed being surrounded by cover I? the branches i'la of which are at a distance from each other substantially equal to the total of these three thicknesses.

If, instead of metallic tiles, I make use of fibrocement or analogous tiles, a particular arrangement is to be used for connection of the tiles with a ridge piece, because, in this case, it is not possible, after having out off a portion of the tile, to form a flange along the new edge. I may, for this purpose, make use of the arrangement of Fig. 12.

As shown by the drawing, I provide an independent flange piece or angle piece l9 one of the sides of which rests upon tile 4 whereas the other side bears against the ridge piece lBb, a ridge-piece cover I? surrounding the whole of said ridge-piece and the last mentioned side of piece I9.

Advantageously, suitable means will be provided for fixing said piece is on purlins 3 and cementing means will be applied to prevent any infiltration of water between the lower wing of piece it and the tile 4 on which it rests.

However, this may b avoided by preliminarily providing, against the ridge piece 561), a piece 13%, for instance of zinc, curved at its lower part so as to form a drain lilBb, whereby any water as may have leaked is evacuated through this kind of gutter iilflb.

Fig. 13 shows a particular embodiment of the invention according to which, instead of keeping the upper flanges of tiles 4 and covers I! in contact with the lower flanges of the corresponding tiles and covers of the row located immediately above (case of Fig. 4) the tiles and covers are made substantially longer than the distance between purlins 3, whereby a space may remain between the corresponding upper flanges 4 and the lower flanges d each tile and cover thus extending slightly beyond (in the downward direction) the purlin 3 on which the corresponding element (tile or cover) is resting.

The interval between said flanges will then be filled by a small block IH.

Furthermore, in order in particular to reduce the height of the respective flanges and also to reduce the load supported by each flange, the upper ends of tiles 4 may rest on a' supporting wood block I52, provided along every purlin on the lower side wall thereof.

It should be noted that block Hi will tend to prevent inflltrations of water between the two flanges located on opposite sides of said block. Fluidtightness of the assembly may be further improved by bending downthe upper edge a of the upper flange 4 of the tile, as shown by Fig. 16. In this case, block HI serves also to prevent crushing of this curved edge.
