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.
Claims9
A drainage device intended to be installed on a construction having an external surface and provided with a discharge channel, the drainage device comprising:
- a drainage head comprising an external wall delimiting a recovery space and having a discharge passage around which the external wall has a support shoulder able to bear on the external surface of the construction, around the discharge channel, and at least one recovery passage;
- and
- a mounting element comprising a support or attachment element capable of being engaged inside the discharge channel, and a biasing element connecting the drainage head and the support or attachment element, the support or attachment element comprising a plurality of elastically deformable arms spaced from each other in the circumferential direction,
- the biasing element being able to act on the support or attachment element, so that the ends of the arms of the support or attachment element, abutting against the discharge channel, under the effect of the biasing element, are able to hold the support shoulder of the drainage head in abutment on the external surface of the construction,
- wherein the support or attachment element comprises a central portion provided with the arms at the periphery thereof, the arms being disposed around the central portion,
- wherein in the engaged position of the attachment element inside the discharge channel, the arms of the support or attachment element are curved towards the drainage head by the radial contact against the internal surface of the discharge channel in a position deformed counter to their elasticity, the ends of the arms bearing against the internal surface of the discharge channel at points spaced apart in the circumferential direction, and
- wherein the biasing element comprises a central rod intended to extend axially into the discharge channel in the engaged position of the attachment element inside the discharge channel and coupled to the central portion of the support or attachment element by screwing to the curvature of the arms during screwing in the engaged position.
