Abstract: A drainage device for a construction, e.g., a roof of a building or a terrace, for discharging rainwater, is provided. The drainage device includes a drainage head supported on the construction around a flow channel and defining a recovery space communicating with the outside and with the flow channel; and a mounting element having a support or attachment element capable of being engaged inside the discharge channel and abutting against the peripheral wall of the discharge channel. The device further includes a biasing element which connects the drainage head and the support or attachment element and is capable of acting on the support or attachment element so as to keep the drainage head supported on the outer surface of the construction.

Abstract: A drainage device is provided. The drainage device includes a drainage head having at least one head portion having an internal collection space and provided with at least one through recovery passage, and an attachment sleeve at least partially deformable. The attachment sleeve can be secured to the drainage head and capable of being inserted inside the flow pipe. The drainage device further includes a compression washer attached on the attachment sleeve and a central screw. The central screw can be movable in relation to the drainage head and threadably engaged with the compression washer to obtain, under the effect of a rotation of the central screw relative to the drainage head, an axial movement of the compression washer on the side of the drainage head and an outward radial deformation of the attachment sleeve.

Abstract: The sealing device for construction comprises a duct and a linking member mounted around and rigidly connected to the duct, wherein the duct comprises: an axial main portion around which the linking member is mounted, a radial bead formed on the main portion and extending radially outwards, and a distal end portion extending the main portion radially outwards and which is axially facing the bead to form therebetween an outwardly radially open annular mounting slot, the distal end portion extending radially beyond the bead, the main portion, the distal end portion and the bead of the duct being made of one piece, the linking member being mounted in the mounting slot and gripped axially between the bead and the distal end portion of the duct.

Abstract: The drainage device 10 comprises: a drainage head 24 internally delimiting a collection space 34 and provided with at least one through recovery passage 36, 38, an attachment sleeve 26 at least partially deformable, secured to the drainage 24 and capable of being engaged inside the flow pipe 20, a compression washer 28 attached on the attachment sleeve 26, and a stressing element 30 movable in relation to the drainage head 24 and cooperating with the compression washer 28 to obtain, under the effect of a movement of said stressing element relative to the drainage head, an axial movement of the compression washer 28 on the side of the drainage head and an outward radial deformation of the attachment sleeve 26.

Abstract: The present disclosure provides sealing devices and construction methods thereof. The sealing devices include a duct having a main axial portion, an intermediate annular portion facing the main axial portion, and an annular end portion facing the intermediate annular portion. The intermediate annular portion and the end annular portion are connected by an annular fold so as to form an axial annular mounting slot that is axially open opposite this annular fold. A connecting member comprises a radial plateau and, around a through-opening, an axial annular mounting portion. The axial annular mounting portion of the connection member is engaged and grasped in the axial mounting slot between the intermediate annular portion and the end annular portion of the duct.
