Firestop device including an expandable fold-out collar

The firestop device comprising a collar to be mounted to a partition surface at a location where a plastic pipe or another non-fire resistant duct penetrates the partition, wherein the collar has an inner side on which an intumescent material is arranged,

• wherein
• the collar is a fold-out collar including a first collar half and a second collar half,
• the first collar half and the second collar half each comprise a semi-cylindrical wall and a radial flange for abutting the wall surface, wherein the semi-cylindrical wall has a radial inner side on which the intumescent material is arranged,
• the first collar half is adapted to be mounted to the partition surface with its radial flange secured in abutment with the partition surface,
• the first collar half and the second collar half having corresponding end portions which are hingedly connected to each other, such that the collar halves are moveable from a folded state, in which the second collar half substantially overlaps the first collar half, to a folded out state, in which the first collar half and the second collar half form a ring shaped collar,
• the device furthermore comprises an actuator arranged and configured to move the second collar half from the folded state to the folded out state.

A firestop device comprising:

• a collar to be mounted to a partition surface at a location where a plastic pipe or other non-fire resistant duct penetrates the partition, the collar including a first collar half and a second collar half, the first collar half and the second collar half having corresponding end portions which are connected to each other;
• a fire resistant extendable and collapsible cap circumferentially connected to the collar and for closing off the penetration location when the pipe or duct is collapsed or destroyed by the fire;
• and
• an actuation assembly for moving the fire resistant cap from a collapsed state to an extended state over the penetration location to close it off;
• wherein
• the collar is a fold-out collar in which said corresponding ends of the first and second collar halves are hingedly connected to each other so as to be moveable from a folded state, in which the second collar half substantially overlaps the first collar half, to a folded out state, in which the first collar half and the second collar half form a ring shaped collar, wherein the first collar half is adapted to be mounted to the partition surface, wherein the fire resistant cap is attached to the first collar half and the second collar half, and wherein the actuation assembly includes the second collar half, said second collar half pulling the fire resistant cap from its collapsed state to its extended state over the penetration location when moving from the folded state to the folded out state.
