- the pins are in the upper edge and/or lower edge of the walls of the room units and openings, which fit the pins, are in the attaching element.
- the attaching element is arranged to cover the space between the walls of superposed room units at least mainly completely.
- the attaching element is thus at least as long and as wide as the entire upper or lower edge of the wall. It can also be conceived that one space between superposed walls is covered with several smaller attaching elements.
- one attaching element is arranged to be as long as the entire building or cabin compartment of a ship.
- a sound-insulating mat or band or a corresponding insulating material is placed in a manner known as such between the attaching element and the walls of the room unit.
- the openings needed for the pin connection can be arranged into this insulating material.
- the arrangement comprises adjacent room units.
- one attaching element can have centering pins and/or centering openings for the lower edges of the walls of two adjacent upper room units and the upper edges of the walls of two adjacent lower room units meant to be underneath them.
- the adjacent and superposed room units are attached to the same attaching element.

- a distance for example 50-500 mm
- insulations or various kinds of cords, pipes and possible support structures can be placed in these spaces.
- the attaching element can thus be as wide as two adjacent walls and the space between them.
- one or more drawbar openings have been arranged in at least two superposed attaching elements.
- One or more drawbars can thereby be arranged through the drawbar openings in the superposed attaching elements. With the aid of the drawbars, superposed attaching elements and thus superposed room units can be held together in the direction of the drawbar.
- the drawbar openings and the drawbar are between adjacent room units. It is possible to attach the drawbars also in other ways than in the attaching elements according to the invention.
- the drawbar does not penetrate the wall structures of the room unit.

Even though there are no great defects in the solutions presented in the above-mentioned publication, new alternatives may in some cases be wanted for attaching room units. Simpler, more easily realized and if possible better functioning solutions are always welcome. - Patent publications
WO 98/40573 JP 11081481 US 3643390 present some manners of attaching room units to each other. - It is an object of the present invention to reduce or even to eliminate problems appearing in the above-mentioned and also other prior art.
- It is especially an object of the present invention to provide a solution, with which the attaching of prefabricated load-bearing room units to each other is made simpler, quicker and more efficient.
- It is an object of the present invention to efficiently provide safe multi-storey structures, such as apartment buildings or cabin compartments in ships.
- It is an object of the present invention to provide multi-storey rooms, for example cabin compartments in ships or apartment buildings, which do not need middle decks or intermediate floors between the storeys.
- In order to realize among others the objects mentioned above, the arrangement, method, ship, building and other objects of the invention are characterized by what is presented in the characterizing parts of the enclosed independent claims.
- The embodiments and advantages mentioned in this text apply, when applicable, both to the arrangement, method, ship and building according to the invention, even though it is not always specifically mentioned.
- The embodiments of the invention are suitable for use in connection with various kinds of ships and buildings.
- A typical arrangement according to the invention for attaching prefabricated load-bearing room units to each other comprises an upper and a lower prefabricated room unit, and attaching means between them for attaching the room units to each other. Typical attaching means according to the invention comprise a pin connection. Additionally typical attaching means according to the invention comprise at least one drawbar, which is arranged to hold superposed room units together in the direction of the drawbar.
- In a typical method according to the invention for attaching prefabricated load-bearing room units to each other, the upper and lower prefabricated room units are attached to each other with a pin connection between them. Superposed room units are further held together with one or more drawbars.
- In this text room unit means a self-bearing unit which is used in construction and which comprises a ceiling, a floor and walls. The room unit can typically be moved in one piece and installed to its location in one piece. The room unit can for example be a prefabricated cabin of a ship or an apartment in an apartment building or a part of an apartment.
- In this text room arrangement means a structure that is formed of several room units, which have been attached together, for example superposed apartments of an apartment building or a cabin compartment in a ship or a part of them.
- In this text prefabricated means that the ceiling, floor and walls of a room unit have been connected together already prior to its installation to its location in a ship or a building. Interior design of the rooms, such as furniture, carpets, wall papers, bathroom design, and heating, plumbing, ventilation and electrical installations, has typically also been made as ready as possible in the prefabricated room unit before the room unit is brought to its installation location. All walls, typically two side walls and two end walls, are preferably ready in the prefabricated room unit. The walls are typically provided with necessary doors and possibly windows. Typically the walls, floor and ceiling also have a necessary number of openings for cords, pipes etc.
- In this text load-bearing structure means a structure, which carries its own weight as well as the weight above it. A typical load-bearing structure forms a support frame for the entire structure, which support frame carries forces directed to the structure, and provides a sufficient functional rigidity.
- In an embodiment of the invention the room units have a ceiling, a floor and at least two walls, which are made at least mainly of cellular board. By using cellular board know as such as a main structure for the floor, ceiling and walls of the room units, an extremely rigid, self-bearing and light structure is easy to achieve. By using cellular boards, the room unit can be made into a self-bearing structure without any specific beam structures or the like. Room arrangements formed of superposed and/or adjacent room units according to the invention can form a self-bearing structure. The room arrangements can also be manufactured of something else than cellular board.
- In this text cellular board means a structure known as such, formed of two substantially parallel surface plates and of a core arranged between them. Typically also the core is of a plate-like material, but its shape has been arranged to differ from the direction of the surface plates, for example by forming folds and grooves between the folds in the plate material. Typically, the core comprises several adjacent and parallel straight shapes having usually mainly the length of the whole cellular board. In this text such longitudinal direction of the shapes of the cellular board core is called a core direction. The cellular board resists bending in a transversal direction in relation to the direction of the cores especially well. Typically the core of the cellular board according to the invention has been firmly attached to the surface plates. For example the surface plates and the core can be welded together, for example by laser welding. Typically the surface plates and the core of the cellular board according to the invention are made of metal, such as steel, for example stainless steel, or aluminium, but also other materials can be used. The thickness of the surface plates and the core of the cellular board, the material, and the shape of the core can be dimensioned to be appropriate for each situation. By means of a cellular board structure, a structure can be achieved, which is considerably lighter, more rigid and has better bending resistance than a continuous plate structure. The shape of the core has a great impact on the rigidity and strength of the cellular board. For example, a core made of steel can have the shape of a wavelike bent plate, where wave crests are typically welded to the surface plates. The cores can also be arranged for example in the shape of a letter V, or formed of plates substantially perpendicular to the surface plates, i.e. of plates arranged in the shape of a letter I. The core can consist of a plate bent in the form of a honeycomb. It is also possible to use beams that have the shape of a pipe, the cross-section of which is circular or another shape, as a core. In an embodiment of the invention the surface plates and the core of the cellular board are of the same material.
- According to an embodiment of the invention the cellular board is manufactured from individual profiles, by joining several profiles adjacently. The profiles are manufactured from a plate-like material, which can be for example steel or aluminium. The plate-like material can on its one or both sides be coated, for example with a PVC sheet. The thickness of the plate-like material can for example be 0.5-5 mm or 0.5-3 mm.
- According to an embodiment of the invention each individual profile is meant to form in the completed cellular board a planar first surface protrusion, a planar second surface protrusion or a core, which is arranged to join the first and the second surface protrusion together. The profiles of the cellular board are attached together so that the first surface protrusions are arranged adjacently and form the first surface plate of the cellular board, the second surface protrusions are arranged adjacently and form the second surface plate of the cellular board, and the cores of the profiles are attached to the first and second surface protrusions, whereby they make up the core structure of the cellular board. The length of the profiles can in the so-called core direction be for example 0.5-20.0 m or 1.0-10.0 m. The width of an individual profile can be for example 0.1-1.0 m, 0.1-0.5 m or 0.1-0.2 m. The thickness of a completed cellular board can be for example 0.1-1.0 m, 0.1-0.5 m or 0.1-0.2 m. A completed cellular board can have for example 5-1000, 10-200 or 20-100 profiles joined adjacently. Generally the length i.e. size of the completed cellular board is approximately the same in the direction which bears more load as the length of the profiles in the so-called core direction. The width of the cellular board in the direction, which is perpendicular to the core direction, can be for example 0.5-50 m, 1-25 m or 5-20 m. In an advantageous embodiment the direction of the cores of the cellular boards, which make up the walls of the completed room module and building, is arranged to be vertical.
- In an embodiment of the invention attaching folds, which fit into each other, have been formed in the edges of the profiles which are to be joined with other profiles. Typically an attaching fold of a profile, which forms the core of a cellular board, has also been arranged to fit in connection with the attaching folds of two adjacent surface protrusions. The attaching folds can be formed so that the attaching folds formed in the ends of three separate profiles in one contact point can be attached to each other. The attaching is easy to perform for example by pressure seaming in a way known as such. Before the pressure seaming or after it, a seam insulating substance, such as a mineral wool sheet or glue, for example urethane glue, can be arranged between the profiles of the cellular board.
- Now it has thus surprisingly been noted that the room units are easy to arrange firmly on top of each other with the aid of a simple pin connection, if the superposed room units are at the same time held together with one or more drawbars. Pin connections are known as such, and several different models of pin connections are suitable for this invention. The pin connection efficiently prevents movement of the superposed room units other than in the direction of the pin. For example if the pins are in the vertical direction, the pin connection efficiently prevents horizontal movement of the room units. By planning the locations of the pins of the pin connections in detail beforehand, the superposed and adjacent room units are easy to install just in the desired position and place in relation to each other. In an embodiment of the invention the attaching means comprise centering pins and centering openings which fit them. The pins can be for example of steel, some other metal or plastic. The edges of the centering openings can be of metal, and a sleeve for example of plastic can be installed on them. The necessary amount and size of the pins and the openings fitting them can be planned separately for each situation.
- With the aid of the drawbars, superposed room units can be held firmly together in the direction of the drawbar. The amount and size of the drawbars can be solved separately for each situation. For example only two, three or four superposed room units can be attached to each other in the vertical direction with one drawbar. On the other hand even an entire multi-storey building can be attached in the vertical direction with one bar. Drawbars are known prior art as such, and they will not be described in this text in further detail.
- In an embodiment of the invention the attaching means comprise an attaching element, which can be fitted between the lower edge of a wall of the upper room unit and the upper edge of a wall of the lower room unit. The centering pins and/or centering openings can be situated in this attaching element. Centering pins and/or centering openings which fit these pins and/or openings can thus be situated in the lower edge of the wall of the upper room unit and in the upper edge of the wall of the lower room unit. Thus the wall of the upper room unit, the wall of the lower room unit and the attaching element are attachable to each other with the aid of a pin connection.
- In an embodiment of the invention the attaching element is a mainly planar steel plate, which is for example 3-100 mm, 5-50 mm or 7-30 mm thick. The centering pins can for example be welded to such a plate, for example perpendicularly in relation to the level of the plate, up or down from the level of the plate.
- In an embodiment of the invention the pins are in the attaching element and openings, which fit the pins, are in the upper edge and/or lower edge of the walls of the room units.
- In an embodiment of the invention the pins are in the upper edge and/or lower edge of the walls of the room units and openings, which fit the pins, are in the attaching element.
- In an embodiment of the invention the attaching element is arranged to cover the space between the walls of superposed room units at least mainly completely. The attaching element is thus at least as long and as wide as the entire upper or lower edge of the wall. It can also be conceived that one space between superposed walls is covered with several smaller attaching elements. In an embodiment of the invention one attaching element is arranged to be as long as the entire building or cabin compartment of a ship.
- In an embodiment of the invention a sound-insulating mat or band or a corresponding insulating material is placed in a manner known as such between the attaching element and the walls of the room unit. The openings needed for the pin connection can be arranged into this insulating material.
- In an embodiment of the invention the arrangement comprises adjacent room units. Thereby one attaching element can have centering pins and/or centering openings for the lower edges of the walls of two adjacent upper room units and the upper edges of the walls of two adjacent lower room units meant to be underneath them. Thus the adjacent and superposed room units are attached to the same attaching element.
- In an embodiment of the invention one attaching element is arranged to extend from the outer edge of the entire building or cabin compartment of a ship to the opposite outer edge. In an embodiment of the invention an edge of the attaching element extends outside the outer walls of the building or cabin compartment of a ship by for example 5-50 cm or 10-30 cm. Other structures, for example a balcony, can be supported on this protruding edge.
- In an embodiment of the invention the centering pins and/or centering openings in the attaching element are arranged so that the walls of two adjacent room units are situated at a distance, for example 50-500 mm, from each other. For example insulations or various kinds of cords, pipes and possible support structures can be placed in these spaces. The attaching element can thus be as wide as two adjacent walls and the space between them.
- In an embodiment of the invention one or more drawbar openings have been arranged in at least two superposed attaching elements. One or more drawbars can thereby be arranged through the drawbar openings in the superposed attaching elements. With the aid of the drawbars, superposed attaching elements and thus superposed room units can be held together in the direction of the drawbar. In an embodiment of the invention the drawbar openings and the drawbar are between adjacent room units. It is possible to attach the drawbars also in other ways than in the attaching elements according to the invention. In an embodiment of the invention the drawbar does not penetrate the wall structures of the room unit. In an embodiment of the invention the drawbar is mainly vertical.
- The lower end of the drawbar can be attached for example to the deck of the ship or the bottom of the building, whereon the arrangement according to the invention has been erected. In an embodiment of the invention only the uppermost storeys of the arrangement are attached to each other with the aid of drawbars. For example the uppermost 2, 3, 4 or 5 storeys in an arrangement according to the invention, which has more than 6, more than 8 or more than 10 storeys, can be attached with drawbars. In an embodiment of the invention the attaching element is arranged on top of the upper edge of the wall of the uppermost room unit and/or below the lower edge of the wall of the lowest room unit. The attaching element is thus not necessarily always between the walls of two superposed room units. Also in such attaching elements, there can be drawbar openings. If the drawbar is attached to such attaching elements, one drawbar can be used to hold together the uppermost or bottom storeys or even all the storeys of the arrangement.
- In an embodiment of the invention balconies mainly outside the room units have been supported on one or more attaching elements.
