Definitions

  • the present invention refers to a ship cabin structure and method of assembly of a prefabricated cabin.
  • This type of floor calls for the floor surface to be separated from the deck of the ship and/or from the vertical walls of the ship structure by means of a layer of material adapted to provide acoustic insulation with regard to vibration transmission.
  • the floor surface is made of cementitious material or metal sheet, whereas the layer of acoustic insulating material is made of mineral wool.
  • the cabin structure is also made once the flooring has been placed on the deck, so that the cabin walls are also decoupled from the ship deck.
  • each cabin is then assembled one by one to build the perimeter of the cabin.
  • This construction technique is used often and is effective at decoupling the deck from the floor surface to reduce the transmission of structural noise between the deck and cabin and thus reduce airborne noise inside the cabin.
  • This assembly technique essentially requires that a prefabricated cabin be made and, once it has been made, it is brought on board the ship, positioned on the deck, and then locked into position.
  • the travel of the prefabricated cabin is impeded due to the reduced vertical space given the thickness of the floating floor.
  • an additional purpose of this invention is to provide a cabin structure that makes for more effective acoustic insulation between the ship's structure and the cabin compared to prior art systems.
  • Yet another purpose of this invention is to provide a prefabricated cabin structure and a corresponding installation method that makes it possible to decrease the transmission of vibrations from the ship's structure to the cabin compared to the systems used in the prior art.
  • Figure 1 shows a ship cabin structure according to one embodiment of this invention, indicated as a whole with reference number 12.
  • Cabin structure 12 comprises at least one wall 14 provided with fastening means 16 for fastening said wall 14 to a deck 18 of a ship.
  • wall 14 may comprise an insulating layer covered with finish surfaces such as sheet metals.
  • wall in the present description refers to a substantially flat surface intended to divide internal spaces and which, in use, sits substantially perpendicular to the position of deck 18.
  • cabin structure 12 is shown with two walls 14, however this does not prevent the cabin structure from comprising a plurality of walls which may be consecutive to each other.
  • FIG. 1 shows a schematic view of an embodiment of fastening means 16.
  • Fastening means 16 comprise:
  • the mounting bracket 20 may have a C-shaped cross-section comprising two arms 28, 30 and a connection portion 32.
  • Connection portion 32 is adapted to be secured to a deck 18 of a ship.
  • mounting bracket 20 may be made of metal such as steel. If mounting bracket 20 is made of metal, it may be secured to deck 18 by means of welding, for instance.
  • figure 2 shows a weld bead 21 connecting the outer side surface of an arm 30 to deck 18.
  • mounting bracket 20 may be adapted to partially contain elastic element 26 between arms 28, 30 so as to protrude from mounting bracket 20 toward said connecting bracket 22.
  • Mounting bracket 20 may comprise a fastening bolt 34 protruding from connection portion 32 in a direction substantially parallel to the direction of two arms 28, 30.
  • fastening bolt 34 may be provided with side projections 35 adapted to engage with a corresponding hole 36 on the elastic element 26.
  • the connection between fastening bolt 34 and corresponding hole 36 is an interference connection.
  • fastening bolt 34 protruding from connection portion 32 in a direction substantially parallel to that of two arms 28, 30, is provided with a threaded portion 38.
  • elastic element 26 is provided with a hole 36 adapted to engage with fastening bolt 34.
  • elastic element 26 may be locked into position on mounting bracket 20 with a nut 40 that engages with a shoulder provided on hole 36.
  • connecting bracket 22 may be provided with a C-shaped cross-section comprising a central body 42 and a first and a second branch 44, 46.
  • Central body 42 can be secured to edge portion 24 of wall 14 so that first and second branches 44, 46 protrude from edge portion 24.
  • First and second branches 44, 46 are adapted to partially contain between them elastic element 26 so that it can protrude from connecting bracket 22 toward mounting bracket 20.
  • connecting bracket 22 has an H-shaped cross-section comprising a central body 42 and a first and a second branch 44, 46, and a third and a fourth branch 48, 50.
  • Central body 42 is designed to be put in contact with edge portion 24 of wall 14 so that first and second branches 44, 46 protrude from edge portion 24.
  • First and second branches 44, 46 are adapted to partially contain between them elastic element 26 so that it can protrude from connecting bracket 22 toward mounting bracket 20.
  • Third and fourth branches 48, 50 are designed to at least partially contain edge portion 24 of said wall 14.
  • connection means 52 may, for example, be a bolt, rivets, or other elements known to a person skilled in the art.
  • connecting bracket 22 and mounting bracket 20 extend in the longitudinal direction for the entire length of corresponding wall 14.
  • brackets 20, 22 could have breaks in continuity along the longitudinal length of wall 14, and be arranged in positions corresponding to each other at regular intervals, for instance.
  • elastic element 26 may be a so-called metal dowel.
  • elastic element 26 may be a metal dowel with steel mesh.
  • the metal dowel is designed to ensure the non-combustibility required by the fire certification (class B) of cabin structure 12.
  • elastic element 26 may be inserted with an interference fit between arms 28, 30 of mounting bracket 20 and between first and second branches 44, 46 of connecting bracket 22.
  • the elastic element may be locked in position with respect to mounting bracket 20 through the use of at least one fastening bolt 34 placed inside hole 36.
  • elastic element 26 may be glued to connecting bracket 22.
  • elastic element 26 may be glued at central body 42 of connecting bracket 22.
  • fastening means 16 will now be described in reference to the longitudinal direction in relation to edge portion 24 of wall 14.
  • fastening means 16 may comprise a plurality of elastic elements 26 along edge portion 24.
  • a panel of mineral wool 52 may be provided between at least two consecutive elastic elements 26.
  • the part of mineral wool 52 in contact with central body 42 of connecting bracket 22 may be glued.
  • the cabin structure can then be preassembled before being placed on the deck.
  • cabin structure 12 may be provided with fastening means 16 comprising a mounting bracket 20, an elastic element 26, and a connecting bracket 22 before being brought on board the ship to be installed on a deck 18.
  • cabin structure 12 comprising a plurality of walls 14 may be installed to make a prefabricated cabin and be subsequently positioned and assembled on a ship's deck.
  • the method for assembling a cabin structure 12 and a floating floor 56 on a deck 18 of a ship comprises the steps of:
  • the floating floor comprises at least one layer of mineral wool arranged with a coating of concrete or sheet metal.
  • floating floor 56 may be made with at least one layer of metal mesh adapted to afford elasticity to the flooring, covered on the top with sheet metal suitable for walking.
  • step (c) between step (b) and step (c) is a step (c') wherein a layer of mineral wool 54 is placed between fastening means 16 and floating floor 56.
  • the layer of mineral wool 54 is built in between the wall and the floating floor to ensure class B.
  • fastening means 16 between wall 14 and deck 18, of a type comprising an elastic element affords a noteworthy reduction in low-frequency noise.
  • an average attenuation of between 5 dB and 10 dB is achieved in the low-frequency range (50 Hz to 200 Hz) compared to a conventional installation in which the wall is installed directly on the floating floor. Furthermore, the attenuation is just as significant at high frequencies.
  • a cabin structure designed to form a prefabricated cabin that allows for installation even on parts of a ship's deck where a floating floor is to be used is made available.
  • the prefabricated cabin may be installed directly on the ship's deck before the floating floor is made, while still maintaining at least the insulation properties that are possible to achieve with a cabin wall installed on a floating floor using the method of the prior art.
  • the insulation properties are increased even more compared to a floating floor installation.
