Abstract

Cover element for forming a floating covering for a liquid tank, comprising a housing (1a, 1b) having a first longitudinal coupling profile (2) and a second longitudinal coupling profile (3), as a result of which two adjacent housings (1 a, 1 b) may be coupled to one another by means of hook hinge profiles (2a, 3a) at the bottom and top coupling profiles (2b, 3b) and a locking profile (7). The end faces of the housings (1a, 1c) are provided with a transverse coupling profile (10) which is configured to cooperate with a sliding coupling profile (9) which is slid over the transverse coupling profiles of both adjacent housings. In this configuration, the cover elements are coupled to one another by a coupling construction that does not protrude beyond the main planes (4a, 4b) of the cover elements, as a result of which the surface of the entire floating roof is smooth, resulting in a substantial reduction in the accumulation of dirt etc. on the roof due to the absence of the vertical coupling flanges.

Dependent claims

A device, intended and configured as a cover element for forming, coupled with similar cover elements, a floating covering for contents of a liquid tank,

which device comprises an elongate housing having a first longitudinal coupling profile on one side and a second longitudinal coupling profile on another side,
wherein both longitudinal coupling profiles are configured such that two adjacent housings may be coupled to one another by means of the first longitudinal coupling profile of the one housing and the second longitudinal coupling profile of adjacent housing,
wherein the first longitudinal coupling profile and the second longitudinal coupling profile do not protrude substantially above or below an upper main plane of the housing,
wherein lower portions of the first longitudinal coupling profile and the second longitudinal coupling profile have a first hook hinge profile and a second hook hinge profile, respectively, which are configured, and shaped, in such a way that the housings may be hooked together at bottom in a hinged manner, after which top sides of said housings may be moved towards each other,
and wherein upper portions of the first longitudinal coupling profile and of the second longitudinal coupling profile have a first top coupling profile and a second top coupling profile, respectively, which are configured to be able to be coupled to one another by means of a locking profile that can be fitted over the first top coupling profile and the second top coupling profile.
