Definitions

• the invention relates to an elastic fastening of structures such as deck houses and. Like. On a ship deck.
• the elastic fastening is arranged in an intermediate space between the superstructure and the ship deck and possibly covered by an apron and consists of rails fastened to the ship deck, the profile of which tapers upwards and that of several on the floor attached to the structure, open at the bottom, possibly combined into a continuous rail parts overlapped, which are secured against lifting and on which elastic bearing elements are attached.
• the bearing elements are generally those which have an elastic body, for example made of rubber or a comparable elastic material, arranged firmly adhering to them between two rigid, preferably plate-shaped parts. The bearing elements are fastened to the profile parts via their plate-shaped parts and sit with the other plate-shaped part on the rail attached to the ship's deck, slipping off being prevented by securing elements welded onto this rail.
• the safeguard against lifting consists of a part on the deck house and on the ship deck or a part that is fixed with it spring-loaded bolts or the like
• Deck structures of this type which are elastically fastened, are, however, only rarely permanently defined in terms of their room layout and, in particular, in terms of their equipment. Rather, they are very often subject to subsequent conversions, which no longer result in a uniform load on the elastic bearing elements prepared and installed as planned.
• an emergency power unit in such an elastic deck house or to increase the comfort of passengers and crew by installing a swimming pool.
• the installation can generally never be carried out in such a way that the load distribution on the elastic bearing elements originally designed for uniformity is retained.
• the size of the load changes can be measured if, for example, the retrofitting of a swimming pool with a floor area of 4 x 4 m and a water depth of 1.6 m is considered.
• a retrofitted swimming pool leads to an additional load of just over 25 t at the corresponding installation point and thus to a corresponding unevenness of the load distribution on the elastic bearing elements, the arrangement of which is designed for the elastic support of the structures without such a swimming pool.
• the invention seeks to remedy this and proposes to solve the problem of being able to even out the load distribution on the elastic bearing elements with the least amount of work, if necessary, that the elastic bearing elements be detachably and displaceably arranged along the rail fastened to the ship deck.
• a sliding bar fixed to the rail is provided, which engages in a corresponding recess on the elastic bearing element.
• the possibility is also created to compensate for a generic position, i. H. a position where the bow is higher than the stern.
• Such positions can lead to a height difference of 4 m if the load of the ship is shifted aft. This can be the case, for example, if a drinking water tank provided in the bow part of the ship is emptied during the journey.
• Other changes in load during travel are possible, for example when deleting goods in such a way that a flat keel is no longer present. Even under such circumstances there are different loads on the bearing elements, the different deflections of which can be measured automatically, if necessary.
• the unbalance of the load can also be compensated for by the fact that new elastic bearing elements are used locally and such bearing elements are removed if necessary.
• the sliding bar can also be provided only in sections.
• a particular advantage of the design according to the invention is that the anti-slip devices provided on the rail fastened to the ship's deck can be dispensed with because their task is fully taken over by the sliding bar.
• elastic stoppers are provided at the ends of the rails by support plates supported by knee plates supported on the deck, which on the other hand were connected to the superstructure and have the task of building the deck in the longitudinal direction of the ship to secure against undesired movement on the rails and to make this elastic resilient.
• the stoppers are pretensioned and the knee plates are screwed to the rail.
• the stoppers themselves are constructed in the manner of the elastic bearing elements. Independent protection is sought for this type of preloaded stopper.
• flanks of the rail or profile parts fastened to the deckhouse floor and thus forming an integral part of the deckhouse floor are provided with holes for fastening the elastic bearing elements. Holes are also provided for the arrangement of support angles.
• these support angles are not screwed directly onto the profile parts, but are fastened to the profile parts via an adjustable wedge with surface toothing. This allows shipbuilding tolerances to be compensated for by appropriate displacement of the wedge, which previously had to be done by burning or planing.
• the elastic mounting elements such as those used in particular for the elastic fastening according to the invention, generally consist of an outer rigid plate-shaped part, an inner rigid plate-shaped part and an elastic body arranged firmly between them.
• a lift-off device which has an elastic pressure plate which consists of two ring bodies, one of which has an inner, boss-like projecting part which over an annular intermediate layer made of elastic material is firmly bonded to the inside of the other ring body.
• the problem also arises here that the screw connections rust due to water penetration and are therefore no longer detachable. Therefore, the intermediate layer is also pulled over the end face of the hub-like projecting part and fastened there firmly.
• Figure 1 is a schematic side view of a deck house, which is mounted on the ship deck by means of an elastic fastening.
• Figure 2 is a plan view of the deck house with dashed elastic attachment, and walls.
• FIG. 3 shows a schematic section along the line III-III of FIG. 2 transversely;
• Fig. 4 is an enlarged detail section along the line
• Figure 7 is a partial section through the top and bottom rails and a support bracket.
• FIG. 9 shows a section through an elastic pressure plate used in the anti-lift device according to FIG. 7.
• the deck house 1 partially shown in FIG. 1 is fastened elastically on the ship deck 3 by means of a fastening device 2.
• Fig. 2 shows that a corresponding division of space in the deck house is made by partitions 4, 4a, 5, 6.
• the elastic fastening is indicated schematically in dashed lines at 7 and has stoppers 8 and 9 at their ends.
• FIG. 3 shows the ship deck 3 and part of the deck structure 1a, 1b.
• the elastic fastening 7 is indicated on both sides.
• a schematic section is shown in each case through a rail 10 fastened on the ship's deck 3, over which a second rail 12 fastened at the bottom on the floor 11 of the deck house 1 sits, which is seated on the rail 10 via elastic bearing elements 19, 20 to be explained in more detail.
• the deckhouse 1 does not rest directly on the ship's deck 3, but is elastically supported on the ship's deck 3 by means of elastic bearing elements 19, 20.
• An apron 13 can be seen in each case, which covers the storage.
• the total with 42 designated lifting safety device is shown in more detail in FIG. 8.
• the rail 10 can be seen in cross section in FIG. 4. 4 shows upper profile pieces 12a and 12b of the second rail 12, which are stiffened by the arrangement 14, but can also be designed as a continuous rail 12 (FIG. 3). They have bores through which screws 15 and 16 are guided, which connect a rigid plate-shaped part 17 and 18 (FIG. 6) of elastic bearing elements 19, 20 to parts 12a, b. A large number of such elastic bearing elements are provided, as are indicated purely schematically in FIG. 1, for example, at 20.
• the rail 10 carries sliding strips 21, 22 which are firmly connected to the rail, for example welded (FIG. 4).
• Corresponding grooves 25, 25a are accordingly provided in the second fixed plate-shaped part 23 or 24 of the elastic bearing elements 19, 20, which engage over the sliding strips 21, 22. While in the previous arrangements anti-slip devices 62, as indicated by dashed lines, were provided on the side cheeks of the rail 10, these can now be eliminated because their function is taken over by the interaction of the sliding strips 21, 22 with the grooves 25, 25a. 4 also shows the apron 13, which covers the elastic fastening of the deck structure. At A the location of a lift-off device 42 is indicated, which will be explained in more detail later in FIG. 8.
• FIG. 5 shows one of the stoppers 8 and 9, which are basically of the same design, namely the stopper 9 (FIGS. 1 and 2) in an enlarged individual illustration.
• a plate 51 is firmly connected to the floor 11 of the deck house 1 via struts 52 and face plates 53.
• the elastic element 54 which is firmly connected to a support plate 55, is supported on this plate 51.
• This support plate 55 is screwed to a plate 57 by means of screw connections 56, which is connected to the ship deck 3 via face plates 58, 59 and brackets 63, the bracket 63 being an extension of the rail 10.
• the elastic element 54 with its on. him fixed support plate 55 is inserted between the plates 51 and 57 and fixed by the screw 56 at its installation location.
• the stop element consisting of the elastic element 54 with its support plate 55 fixed to it is installed in the prestressed state.
• Suitable means e.g. B. the elastic element 54 penetrating Switzerlandsschreibauben 61 used. These are in threaded holes or threaded sockets, which are attached to the support plate
• both plates 60/55 are vulcanized onto the elastic element 54 or are connected to it in a suitable manner.
• the face plates 58 and 59 are not welded directly to the ship's deck, but are detachably screwed to the bracket 63 or rail 10 in a suitable manner, so that the stopper element 8, 9 can be relaxed without any risk of replacement.
• Fig. 6 shows how an elastic bearing element 19 is constructed.
• the fixed plate-like part 23 has the groove 25 (FIG. 4) and consists, for example, of metal.
• the fixed plate-like part 17 has the threaded bore 15a for receiving the fastening screws 15, which are indicated in Fig. 4. It can be seen in the sectional view shown in Fig. 6 that the elastic part 19a between the plate-like parts 17 and 23 overlaps the edges 17a and 23a and thus prevents access of moisture along the inner wall of the fixed plate-like parts 17 and 23, which from is of particular importance in the plate-like part 17, because there in particular the access to the threaded bores 15a along the contact surface between elastic Part 19a and plate-like part 17 is prevented.
• FIG. 7 a partial section from 12a is indicated, the upper rail 12 or a profile section 12a, while at 10 a partial section is drawn from the lower rail.
• support brackets 26 are normally fastened, which prevent the deckhouse from completely sagging in the event of failure of the elastic bearing elements 19, 20, but rather only permit such a movement to a small extent, which is indicated at D in FIG. 7.
• This dimension can be changed in that, according to the invention, the support angle is divided into two parts, namely into the actual support angle 26 and into a wedge part 27, which has a large elongated recess 28.
• the wedge part 27 can thus be moved relative to the support bracket 26 after loosening the screw 29 and the nut 30, as a result of which the distance D can be changed accordingly.
• Wedge part 27 and support bracket 26 are secured against each other by a flat toothing 28a.
• the elastic fastening shown is imperfect if lifting safeguards 42 are not provided. These lifting safeguards 42 are spaced at intervals along the rail 10 (see FIG. 2) and have, for example, the appearance according to FIG. 8.
• the exemplary embodiment shown is in each case elastic pressure plates arranged on the rail 12 and on the rail 10 via brackets 32 and 33, which are identical in the exemplary embodiment shown and, according to FIG. 9, consist of a ring 34 and a further ring 35, which are provided with through openings 36 and 37, through which - covered by a sleeve 38 - a screw 39 (FIG . 8) is passed, which receives at its two threaded ends a nut 40 and 41, respectively.
• the two rings are connected to one another by a rubber intermediate layer 43 which, in the exemplary embodiment shown, covers the end face 44 of the hub-like projecting part 45 of the ring 35 and thus protects this surface exposed to the open (see FIG. 9).
