A fireproof covered structure for covering a penetration part formed in a fireproof beam of a wooden building to make the penetration part fireproof, wherein a tubular fireproof covering material is attached to the penetration part while covering an inner peripheral surface of the penetration part. The tubular fireproof covering material is formed by stacking a plurality of gypsum board pieces cut out from commercially available gypsum boards of thicknesses of 9.5 mm to 25.5 mm, in the thickness direction and unitarily connecting the gypsum board pieces. The tubular fireproof covering material is inserted into and attached to the penetration part such that a connecting portion That connects gypsum board pieces That are adjacent in the stacking direction is disposed at a boundary portion between a structural member and a covering member of the fireproof beam, or at a portion close to the boundary portion.

A hose is provided capable of meeting fireproof requirements per AS1055 under no flow condition. The hose has multiple layers of fire protection comprising a silicone rubber layer impregnated with additives including zinc borate and expandable graphite.

A firestop assembly configured for sealing about a pipe extending through a passage in a building structure division with a sealing element sealing the passage about the pipe. The firestop assembly includes a tube configured to be positioned about the pipe and secured relative to the building structure division. An intumescent material is positioned within the tube. A heat reduction insulation is supported by the tube such that the heat reduction insulation extends about the sealing element and minimizes heating of the sealing element.

A fire prevention apparatus includes an inner pipe having multiple perforations along a length of the inner pipe. The fire prevention apparatus also includes an outer pipe surrounding the inner pipe, the outer pipe having a slit along a length of the outer pipe. The fire prevention apparatus also includes fire retardant disposed in a gap between the inner pipe and the outer pipe. The outer pipe is configured to compress when a force is applied to the outer pipe, so as to cause the fire retardant to pass through the perforations into the inner pipe.

The present invention concerns in particular the nautical equipment sector, with particular reference to the installation of pipes on board of boats of any size and kind. In particular, the present invention deals with safety devices for routing pipes between different sectors of the hull, passing through the bulkheads separating the various vans/spaces/housings of a boat. More specifically, the present invention describes a device (1) for the passage of pipes (5) for liquids or gases through bulkheads and decks of yachts, mega yachts and naval vessels in general with fireproof characteristics preferably and in a particularly innovative way, even watertight/tight.
