Title:
RISER CLAMP WITH A VIBRATION ISOLATION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/078710
Kind Code:
A8
Abstract:
An isolation element for a riser clamp has two opposed clamp halves made of metal strip. Each of said clamp halves has a semi-circular section placed opposite each other against a riser pipe extending through a passage hole in a floor. The clamp halves have at the ends of its semi-circular section outwardly extending clamp flanges to be tightened towards the corresponding opposing clamp flanges of the other clamp half. The riser clamp is in use supported from beneath by a support structure e.g. a floor. The isolation element is adapted to be provided on at least one of two opposing damp flanges and to extend only along said at least one clamp flange. The isolation element includes a profile of vibration isolating material comprising a pad portion, which pad portion in use is located below the corresponding clamp flange for resiliency supporting it, and further comprising at least one upstanding portion extending along the corresponding clamp flange, wherein said upstanding portion is attachable to the corresponding clamp flange. The isolation element furthermore includes a reinforcing profile made of a stiffer material than the vibration isolating material. The reinforcing profile has an angular shape comprising a web and a first flange which are joined at an angle portion, wherein the first flange of the reinforcing profile is associated with the pad portion and wherein the web is associated with the upstanding portion of the isolation element.
