DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a sanitary cell for mounting on a bearing structure of crafts and comprising frame elements, functional units, connection conduits having coupling members for connection with the fixed installation conduits and/or functional elements of the craft and fitting elements.
The present application particularly relates to sanitary cells in the form of toilet rooms for mounting in crafts in the form of train wagons. However, the invention will also be applicable in combination with other kinds of sanitary cells in other kinds of crafts.
Thus, the invention also relates to sanitary cells in the form of shower rooms, kitchen rooms and other rooms with technical installations designed to be mounted in crafts for transport by sea, on land and in the air, such as ships, busses and aeroplanes.
Thus, the invention may advantageously be used in all crafts in which a large part of the craft construction has been completed before the mounting of the sanitary cell is initiated. However, the invention and the advantages obtained by it will subsequently only be described with reference to the building of toilet rooms in train wagons.
When building train wagons, one would first mount a wagon frame with wheels and installations related thereto. Next, the outer enclosure in the form of outer walls, floor and ceiling as well as the fixed installation conduits are mounted therein. Then the inside furniture and room partitions as well as the installations that are necessary therein are mounted. So far toilet rooms have been mounted as one of the last things. It has been normal so far for 3 to 5 different trades to work with the mounting and for the total mounting time to extend over 2 to 3 weeks.
This is disadvantageous in several respects.
Thus, mounting takes place in such a manner that the trades in several turns accomplish a partial mounting of the functional units or fitting elements falling within their field of trade. The mounting time is consequently very dependent on a tight and precise control of the partial mountings of the individual trades. If a single, in itself minor, mounting operation is delayed, it will make a subsequent mounting operation impossible or cause considerable delay for it. Therefore, even minor deviations or delays may have considerable influence on the total mounting time of the toilet room and consequently on the time of delivery.
The toilet room is built up as an integral assembled part of the train wagon. Due to the tolerances involved in building it is necessary to perform an individual adaptation of many components. This is very time-consuming, and such individual adaptation may further give rise to considerable delay in subsequent mounting operations.
The fitting elements will often be mounted in an initial stage as they serve as full or partial support of functional units and/or connection conduits. As a major part of the fitting elements is composed of thin cover plates, a damage to these frequently occurs during subsequent mounting of unhandy and heavy elements such as frame profiles, toilet bowl, pipes and the like. This has made time-consuming replacements necessary, wherein there may also have been a need for the cooperation of several trades in dismounting and remounting.
As mentioned, the fitting elements are thin cover plates. In use they are exposed to a load that may cause them to be broken and to require frequent replacements. As the fitting elements serve as full or partial support of technical installations, such subsequent replacement will make it necessary for the train wagon to be taken out of operation for a long period. Thus, there will be a frequent need for dismounting several elements that require the cooperation of several trades. This is obviously time-consuming and costly.
As the toilet room is constructed as an integral part of the train wagon, and since the fitting elements and technical installations are built together, it requires quite considerable storage capacities to be able to produce train wagons wit
