BRIEF SUMMARY
FIELD OF THE INVENTION
The invention concerns a construction module comprising a fire proof cover plate and a base plate of a cellular light weight material. The invention also relates to a method for producing such modules and the use of the module. A module of this type is known from U.S. Pat. No. 4,557,961, corresponding to WO-84/04727. The present invention is especially developed with a view to its being used for laying floors on board ships and other areas with a large floor space, but will also be able to be used in practically all environments and thereby also in connection with both ceiling and wall spaces.
BACKGROUND OF THE INVENTION
When surfaces are covered, after smoothing a coating is normally affixed to a base surface, or panel plates or other plates can be attached to battens for covering. Where floors are concerned it will be essential to have a flat surface on which boards, planks or, e.g. parquet blocks are laid in a certain pattern, which have to be glued or affixed to one another in order to provide a continuous surface. In order to provide it with sufficient rigidity, these planks or boards will have to be relatively thick and when hard wood is employed this will also entail a relatively large weight load on the base.
Particularly in connection with public places such as in assembly halls, but especially also on board ships, there are increasingly stringent requirements for the use of fireproof materials. This also applies to floor materials and other coverings. At the same time on board ships, for example, there is a desire to use wooden floors, both from traditional as well as practical and decorative considerations. On ships and other means of transport, however, weight is also important and a solid wooden floor implies a major weight load.
In connection with fitting out aircraft, where weight is also a crucial consideration, a panel has been developed with a metal core in the form of an open cell structure, a so-called waffle structure, on which by means of adhesive films on both sides of the metal structure there are affixed thin cover plates, which are preferably impregnated with a fire-retardant agent. These are regular cover plates or panels intended for mounting by conventional means. A panel of this type is described in the above mentioned WO-84/04727, corresponding to U.S. Pat. No. 4,557,961. Similar panel types are also described in SE 429988 and SE 430180.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a module, a method for production thereof and use thereof, the module permitting surfaces to be constructed in a simplified manner compared to conventional laying or construction methods, while at the same time permitting a rationalization of the manufacture, thus enabling a surface to be completed in a substantially shorter time than by conventional means. A second object of the invention is to produce a module of the lightweight type which simplifies the manufacture of the completed surfaces, thus enabling the work to be performed in a shorter time and at a lower cost.
These objects are achieved with a module, a method and a mode of application which are characterized by the features presented in the patent claims.
By means of the invention, for example, a weight saving of up to 2/3 of the weight for a conventional wooden floor constructed from a hard wood can be achieved in the construction of ship's floors or decks. By means of the invention prefabricated modules are obtained, with which relatively large surface units which are connected can be laid at the same time. The construction of the modules can be arranged so as to provide the maximum size possible in order to enter the room through suitable openings. Due to the basic element of cellular light metal, the element will have an inherent rigidity, thus enabling large surface modules to be transported and the form of construction results in a weight which is so low that transport does not represent a problem.
Since the module's rigidity is provided by the light metal structure, a ve
