Complementary adaptation elements, formed along the adjacent internal edges of the adjacent composite panels provide a second connection between the inner faces of said composite panels, to avoid differential vertical movement between one inner face and the other, for the purpose of preventing the degradation of the vapor barrier on the inner face of the roof structure.

The present invention is particularly useful in composite roof panels, of the type comprising an inner liner, an outer liner and an insulating core that connects the inner liner in relation to transfer of shear stresses to the outer liner.

The present improved seal is characterized by the fact that the outer liners have a first and second side walls that extend upwards, formed along the adjacent longitudinal edges of the outer liners, first connecting means, in shape of a nerve usually your * * · • · · bular, are provided along the upper edge of the first side wall.

This joint is further characterized in that a tongue is formed along the longitudinal edge of one of the internal linings and that extends laterally outwardly thereof, and because a groove is formed, complementary along the longitudinal edge of the internal sheath4 adjacent and extending laterally into it. The tongue penetrates into the complementary groove in order to provide a positive mechanical connection between the inner linings.

The present gasket is also characterized in that a seal material disposed within the internal space between the first and second tubular ribs, provides a hemetic weather seal on the exposed surface of adjacent roof panels.

The coatings -11- and -12- can have an inlay design and have a decorative coating, applied on ··· * • their external surfaces. The insulating core -13- can comprise any insulating material; preferably it comprises a foamed plastic material, such as polyurethane which is foamed in; if you between the coverings -11 and -12-. To improve the light covering capacity of the roof panel -10-, the external lining -11- can be provided with upwardly projecting ribs -14-. The remaining portions of this outer liner can be profiled as shown in Figure 1. The inner liner -12- can be provided with spaced depressions -15-. This profiling of the two coatings

-11- and -12- helps eliminate undulation, thereby improving the appearance of their external surfaces.

Along the opposite longitudinal edges of the outer sheathing -11- first and second marginal connecting means -16- and -17- of this invention are provided, and along the opposite longitudinal edges of the inner sheathing -12- It has provided first and second adaptable elements -18- and -19- of the invention itself. The outer covering -11- is displaced laterally with respect to the inner covering -12- to improve the thermal efficiency of the joint. The insulating core -13- has an exposed surface -20- in the region between the first connection means -1 6- and the _or .

With reference to Figure 2, the outer liner -11- includes a central outer bore -21- having first and second upright side walls -22- and -23 that extend upwards from the opposite longitudinal edges of the bore -21- . The first connection means -16- comprise a generally tubular rib -24-, formed along an upper edge -25- of the first side wall -22-, which comprises an incomplete circumference and has a terminal flange - 26- which extends tangentially from said nerve, downwards and towards the central outer bore -21-. A longitudinal opening 927-, formed between the terminal flange -26- and the upper edge -25-, provides a communication with the inside of the rib -24-. The second connection means -17- comprise an open and arched loop -28-, formed along an upper edge -29- of the second side wall -23- and having an ellipse-like cross-sectional profile (for the For the purposes of the illustration, a dashed ellipse has been indicated in -30-) · The open loop -28- extends away from the central upper bore -21- and includes a terminal strip and turned inward -31-, which extends towards outside and towards the plane of the outer bore -21-. On the inner surface of the open loop -28- and along the entire length of the same, a strip -32-, relatively wide and · '· * is applied.

of a suitable sealing material. . ζ · ..

To facilitate the formation of the gasket of the invention and to avoid an upward, unnecessary and undesirable bending of the open and arched loop -28-, the strip. I.

terminal and turn in -31- is arranged at a level (height -33-) located above the level (height. · • · * ·

-34-) of the tubular nerve -24-. ' Thus, with reference to Figure 3, the terminal strip and turned inward -31B- freely passes over the tubular rib -24A- when the second roof panel -1OB- is moved towards the first -10A-. When the loop -28B- and the nerve -24A- are inter-coupled as in Figure 3, a suitable self-acting shaping device is used, which incorporates shaping rollers, to bend and close the loop -28Wrap around the nerve -24A- in order to form , with the aid of sealant -32B-, a primary and weatherproof seal, illustrated in Figure 4. It will be seen in this last figure that the terminal strip and turned inward -31B8 extends around the terminal flange -26A- now bent, and engages with it, and extends through the longitudinal opening -27 A-, inside the nerve -24A-. The loop -28b-, now closed, and the nerve -24A- are interlocked securely and exclude the entry of rain or other liquids driven by the wind through the primary joint.

The primary seal can also be formed as indicated in Figures 5 and 6. a sealing material and ·.

-28- is closed, the terminal strip and turned inwards -31penetrates into the flexible and sealing material -44- as indicated in Figure 6. if desired, the sealant strip -32 «indicated in figure 2, can be provided between the inner ribs * and · * · in addition to the sealing and flexible material -44 From a comparison between figures 3 and 4, a20 will appreciate that when the shape of the loop -28B- is transformed from the generally elliptical to a generally tubular one, essentially only an arc segment, identified with -35- in Figure 2, undergoes bending. It is also noteworthy that the terminal strip and turn inwards -31B- cut.25 serve its arcuate shape. Original · Thus, due to its initially elliptical shape, the loop -28B- experiences only smaller bending requests when it is closed around the nerve -24A-. Consequently, a corative coating that is applied to the outer surface of the external coating -11- will not experience any undesirable deterioration when the loop -28B- is closed. Since only minor bending stresses are presented, the number of different types of decorative coating materials that can be applied to the coating -11- is significantly increased.

With reference to Figure 2, the first adaptable element -18- comprises a tongue -36- that extends laterally outward from a longitudinal edge -37- of the · "• · ·&gt;

* · Central internal bore -41-. The second adaptable element -19- comprises a complementary groove -38- that extend. · ♦ ** * »from laterally into the opposite longitudinal edge ·&gt; ·«.

-39-. The slot -38- is provided with a second sealant 'Z * «

-40-. The tongue ^ 36- and the groove -38- extend generally parallel to the inner bore -41- and meet.

between the planes of the latter and the external bore -21-. '··.

When assembling adjacent roof panels -10A- and

-10B- in collateral relationship as indicated in Figure 3, the tongue -36a- enters the groove -38b- and penetrates the sealing material -40B-, forming with Qllo an effective sweep against the vapor in the part board internal. The central internal bores -41 A- and -41B- of the adjacent panels —1OA— and —10B— provide a continuous internal surface.

The outer and inner liners -11- and -12 are made of a material that has a selected development. When manufacturing the roof panel -10-, the shape of the arched bu10 -28- and the complementary groove -38- are preserved as illustrated in Figure 2. Consequently, if the development of the material exceeds that selected, the excess or excess material will appear, in the outer covering -11-, as a flange illustrated by the outline of strokes -42-, which extends into the interior of the tubular nerve -24-, while in the outer covering -12- it will appear as an extension, indicated with dashed line in -43-, of the tongue -36-. The flange -42- will not interfere with the connection formed between the loop -28- and the rib -24-, and the extension -43- will not interfere with the fused connection between the tongue and a groove, nor with the placement of the fixing means
