  • the resilient supports can be e.g. steel springs or rubber-containing support elements.
  • the base frame can also comprise a plurality of resilient supports for supporting an engine and/or a generator against the base frame.

  • Fig. 2 shows a cross-sectional end view of a base frame according to an embodiment of the invention.
  • FIG. 1 shows schematically a cross-sectional view of a base frame 1 according to an embodiment of the invention.
  • the base frame 1 is a common base frame for an engine 4 and a device driven by the engine 4.
  • the base frame 1 supports a piston engine 4 and a generator 5.
  • the engine 4 is a large internal combustion engine, such as a power plant or ship engine.
  • the rated power of the engine 4 is at least 500 kW.
  • the generator 5 is coupled to the engine 4 with a flexible coupling 6.
  • the coupling 6 transmits the torque of the engine 4 to the generator 5 but allows movements of the engine 4 and the generator 5 in relation to each other in other directions.
  • the base frame 1 could be used for supporting a pump that is coupled to the engine 4.
  • the base frame 1 has a sandwich structure.
  • the base frame 1 comprises a core 2 and a shell layer 3.
  • the shell layer 3 completely encloses the core 2.
  • the shell layer 3 thus forms a casing, inside which the core 2 is arranged.
  • Be- cause of the sandwich structure of the base frame 1 the core 2 together with a relatively thin shell layer 3 forms a rigid structure capable of supporting a large piston engine 4 and a generator 5.
  • the core 2 of the base frame 1 can be a solid block. An advantage of a solid block is that it is easy to manufacture by casting.
  • the core 2 can be provided with one or more cavities. The cavities can be used for making the structure lighter. In addition, the cavities can be used for accommodating functions needed by the engine 4 or auxiliary devices of the engine 4.
  • the core 1 can be provided with a duct for intake air of the engine 4 or the cavities can be used for accommodating cooling liquid channels.
  • Figure 2 shows an embodiment of the invention, where the core 2 is provided with cavities 8, which are used as intake ducts.

  • the core 2 could also be formed of several parts.
  • the shell layer 3 is made of a metal or an alloy.

  • Sheet metal refers here to a sheet-like material that is made of a metal or an alloy and has a thickness of not more than 6 mm.
  • the shell layer 3 is made of steel.
  • the shell layer 3 can have a uniform thickness, or the surfaces 3a on which the engine 4 and/or the generator 5 are arranged can be made of a thicker material.
  • the shell layer 3 is made of a plurality of sheets or plates, which are joined together by welding.
  • the core 2 of the base frame 1 is at least partly made of concrete.
  • crete refers here to a building material obtained by mixing cement, water and any suitable additional substances, such as sand.
  • the core 2 can be reinforced, for instance, by steel bars that are embedded in the core 2.
  • the core 2 can also be pretensioned to increase the tension stiffness of the base frame 1 .
  • all the parts forming the core 2 comprise concrete.
  • the core 2 could consists of one or more blocks comprising concrete.
  • the core 2 could also be formed of one or more parts comprising concrete and one or more parts made of some other material or materials, such as steel.
  • the base frame 1 is easier and less expensive to manufacture than conventional base frames. Compared to a conventional steel structure used for supporting an engine and a genera- tor, the base frame 1 according to the invention needs less weld seams. The seams are also easier to make and the manufacturing process can be automated to a greater extent.
  • the base frame 1 can be manufactured by first forming the shell layer 3, but leaving at least part of the upper surface of the shell layer 3 open. After forming the shell layer 3, possible reinforcing bars and/or cores needed for forming cavities 8 into the base frame 1 are arranged into the space formed by the shell layer 3. After that, the concrete can be cast- ed to form the core 2 inside the space formed by the shell layer 3.
  • the shell layer 3 can be completed by closing the openings which had been left for the casting of the concrete.
  • An alternative way to man- ufacture the base frame 1 is to form the core 2 first and then enclose the core 2 inside the shell layer 3.
  • the properties of the base frame 1 can be improved by suitable selection of the start materials of the core 2.
  • the core 2 or part of the core 2 can be made of lightweight concrete.
  • lightweight concrete With the use of lightweight concrete, the weight of the base frame 1 can be reduced.
  • the term "lightweight concrete" re- fers here to both lightweight concretes made by using lightweight aggregates and lightweight concretes made by increasing the porosity of the mixture making up the concrete.
  • the latter group of lightweight concretes includes, for instance, autoclaved aerated concrete (AAC).
  • AAC comprises aluminum powder, which reacts in the manufacturing process with calcium hydroxide and wa- ter to form hydrogen.
  • the hydrogen gas causes foaming of the mixture and increases the volume of the mixture. Later during the manufacturing process the hydrogen escapes from the concrete and is replaced by air.
  • the result of the process is solid but still soft material, which has a much smaller density than normal concrete.
  • the blocks are placed in an autoclave chamber, where they are held in increased temperature and pressure for 12 hours.
  • quartz sand reacts with calcium hydroxide and forms calcium silica hydrate, which gives AAC its characteristic properties.
  • the properties of the core 2 can also be improved by mixing rubber with the other substances used for manufacturing the concrete.
  • the rubber in the con- crete improves the damping properties of the base frame 1 .
  • crushed car tires are mixed into the core material.
  • tires also contain steel fibers, which function as a reinforcing elements in the concrete.
  • the base frame 1 can be provided with resilient supports 7 for supporting the base frame 1 on a floor surface of a power plant or against the hull of a ship.
  • the resilient supports 7 can be, for instance, steel springs or support elements, which contain rubber.
  • the resilient supports 7 below the base frame 1 reduce transmission of vibrations from the base frame 1 to the surface supporting the base frame 1 .
  • the engine 4 and the generator 5 can be either rigidly mounted to the base frame 1 or resilient supports 9 can be arranged between the base frame 1 and the engine 4 and/or the base frame 1 and the generator 5.
  • Figure 2 shows resilient supports 9 that are provided for mounting an engine 4 onto the base frame 1 .
