A device for supporting and attaching panels to a roof including an added sealing covering on the surface thereof includes brackets for tiltedly supporting and bearing the panels, including a bottom bearing portion and at least one top portion for supporting the panels, the brackets having a triangular structure and consisting of a hollow body. The device is characterized in that the bottom portion () of the brackets () is provided, on the underside thereof, with at least one added plate () secured to the console (), wherein the plate(s) () consist of a material or contain a material that is compatible with and/or similar to the layer or the surface coating of the roof covering (), and are bonded to the layer or the covering by an adhesive bond, and in that the top portion (') provides bearing surfaces for the edges of the panels or profile members for mounting such panels.

Device for supporting and attaching panels or the like, and roof system comprising such a device

A device for fixing elements in the form of plates to a roof cover for a building, at a distance therefrom, the cover including, on the surface, a coating or a sealing layer attached to the essentially continuous support forming the roof, the device including blocks that can be height-adjustable or not, for supporting and holding the plate-shaped elements, each block having a base with a lower smaller plate to be applied to the surface of the cover and secured thereto, and a head or upper part for directly or indirectly supporting at least one plate-shaped element, the bottom face of the smaller plate () of the base () of each block () being provided with a part () of the plate, forming a protector, which is mechanically fixed to the smaller plate ().

Device for fixing plates or panels to a cover, and resulting composite cover

The present invention has for its object a prefabricated sealing membrane formed by a support, coated on at least one surface, and preferably impregnated throughout, with a modified bitumen base composition, characterized in that the thermoplastic bituminous composition for coating and/or impregnation is a bituminous binder modified by a thermoplastic polyurethane having the following weight proportion:

Prefabricated membrane based on modified polyurethane bituminous binder and process for production

A waterproofing UV-resistant bituminous membrane, a system incorporating such a membrane, and a manufacturing process are disclosed. In a particular embodiment, a UV-resistant waterproofing membrane includes a mass of at least one bituminous composition, formed in at least one continuous layer, and of at least one ply of filamentous or fibrous material, embedded in the mass. The membrane is characterized in that the at least present bituminous composition consists of a bituminous mixture based principally on bitumen, SBS elastomeric polymer and mineral fillers and in that said at least one ply () consists of a fine web, of open-work structure, with no preferred direction of stress resistance and formed of filaments and/or fibers in a material that is preferably resistant to UV, said web () being embedded in the mass () of bituminous composition(s) while being situated next to the face () designed to be visible or exposed, after laying said membrane ().

Waterproofing UV-resistant bituminous membrane, system incorporating such a membrane, and manufacturing process

A greening device for fa&#xe7;ades or walls, consisting mainly of a support structure fixed on the fa&#xe7;ade to be covered and by at least two modules with flat structure and square or rectangular profile, containing a cultivating substrate and including on one of its large surface apparent vegetation elements, the modules being removably mounted on the support structure substantially concealing the latter. The support structure includes at least two spaced apart vertical rails whereon the modules are mounted in vertical rows being located away from the fa&#xe7;ade or wall and being individually detachable, each module being in the form of a box with globally flat parallelepiped structure of slight thickness compared to its lateral dimensions, the open side of the box opposite the base being closed with an open-work wall. The vertical opposite side walls have catching elements designed to co-operate with reception sites on the mounting rails.

Modular greening device for facades, walls or the like

A process and an installation for the production of a bituminous sealing sheet, comprises a strip impregnated and/or coated with a given bitumen and having a zone in the shape or a band or a portion of a band of a different bitumen from the first bitumen. A strip ( ) is produced which is impregnated and/or coated except for at least one zone in the form of a strip or a strip portion ( ) on at least one of its surfaces ( ), having a thinner thickness of bitumen ( ) or no application of bitumen ( ), to be used at the at least one strip or strip portion ( ), over a controlled thickness, a different bitumen ( ) from that initially applied and finally, after cooling and solidification of the eventually added bitumen ( ), processing the resulting sheet or sealed membrane ( ) 5 in the desired form, the processing operations being carried out by continuous movement of the strip ( ) in an installation ( ) or suitable coating line comprising at least two coating stations ( ).
