Definitions

  • the invention relates to a floating element made of an essentially prismatic plastic hollow body which has connecting parts on the side walls, preferably in the side edge regions, for assembling with other identical floating elements.
  • Such floating elements can be used for floating platforms, boat and landing jetties, but also for work platforms, transport rafts, bridges, oil and dirt barriers and the like. The like. Compose and have already proven themselves due to their diverse range of uses. So far, however, the floating elements consist of closed hollow bodies, the production of which is relatively complex and which, particularly because of their low immersion depth, swim a little uneasily and under load, in waves and. The like. Quite strongly fluctuate.
  • EP-A-0015 352 shows an industrial platform which consists of a floating steel structure with buoyancy chambers formed from web walls and opening downwards. Pipe sockets protruding into the chambers allow ventilation and thus an adjustment of the respective water level in the chambers in order to be able to adapt the buoyancy effect to the different loads. There is a large structure that practically does not allow any comparison with small generic plastic floating elements.
  • the invention is therefore based on the object of providing a floating element of the type described at the outset, which ensures the assembly of a particularly stable, calmly and securely lying on the water platform or the like with little effort, light weight and skillful handling.
  • the plastic hollow body is open in a manner known per se Has underside and at least one air hole arranged at a distance from the underside is provided in the walls.
  • the open underside allows the water to penetrate into the cavity of the floating element to a depth determined by the arrangement of the air hole, so that the water which has penetrated into the hollow body ensures the stable, low-fluctuation floating position of the floating element.
  • the hollow body, which is open at the bottom, is efficient, for example, can be produced by a spraying process, and the missing underside helps to save material and weight.
  • the air hole is dimensioned relatively small, for example with a diameter of 1 or 2 mm, the element sinks slowly only to the extent of the possible air escape, but the remaining cavity can only be ventilated slowly when there is a swell and the air hole is released, which is one of the swell largely undisturbed quiet location guaranteed. Strong fluctuations or even an undesirable lifting of the elements from the water is practically impossible and the swimming stability can be easily adapted to the different conditions by selecting the hole spacing from the underside and also by selecting the hole dimension.
  • the hollow body is divided into chambers which are open at the bottom by at least one partition and each chamber is provided with an air hole, the floating position is rationally further stabilized, since the water cushions in the individual chambers counteract mutual level differences and thereby make tilting movements of the floating element considerably more difficult , where four chambers are advantageously prepared by two intersecting partitions, each having the air hole in one of its outer walls. If internal chambers are provided, which are only delimited by partitions, these chambers are connected to the neighboring chambers through their air holes connected or they can also be ventilated through the top, but this does away with their contribution as a buoyancy chamber.
  • At least one wall has a height measuring scale for the subsequent setting of the air holes, drilling the air holes on the spot of the area of use can be facilitated according to the respective circumstances, the measuring scale simplifying and maintaining the selected distances from the underside, especially in the case of several air holes the use of the floating elements can be used to read the immersion depth.
  • the plastic hollow body has an open underside and is divided into chambers that are open at the bottom by at least one partition, each chamber accommodates an air duct that runs vertically and is attached to the top wall of the hollow body and that passes through an air hole the top wall air-accessible air duct consists of a corner chamber delimited by web walls in a corner region of vertical wall inner edges and forms an inlet opening at a distance above the underside.
  • the hollow body is evenly vented and the floating elements sink in evenly until the water rising inside the hollow body closes the inlet openings of the air ducts, the air holes on top not being able to be moved or even closed by adjacent floating elements or the like. which would affect the ventilation. Because fluctuations and Wave movements in the interior of the hollow body in the area of the inlet openings are only attenuated and softened in comparison to the outside, there is no longer any fear of exposing the inlet openings and the floating element lies in the water with a safe, constant depth of penetration.
  • the manufacture of the hollow bodies remains simple, since the corner chambers forming the ducts can be produced practically without additional effort in the course of the hollow body production, for example in the injection molding process, the web walls of the air ducts bringing additional stiffening of the hollow body or the partition walls.
  • the floating elements are usually cambered on the top and rounded in the upper edge areas, and it is also possible to stack the floating elements on top of one another to increase the platform or the like. If the end faces on the underside of the side walls and dividing walls and any stiffening ribs which may be present have a shape which is adapted to the rounding of the upper side, when the elements are placed one on the other, the elements are centered and positioned securely.
  • a fender which consists of a longitudinally slotted plastic tube forming angled slot flanges outward to fastening flanges, horizontally attachable to the tabs on the adjacent free side walls of at least two assembled floating elements and with the thickness of the tab thickness being interposed adapted washers can be screwed tight, this fender allows the tabs on the free sides of the platform to be clamped together perfectly, as in conventional connecting knots, so that a constant, firm floating element connection is also created in the edge area of the platform.
  • the fender at the same time the desired collision protection for boats or the like. achieved, whereby the fenders also create a supply channel through their tube shape, through which water or power cables are laid but also the air lines for ventilation of the chambers can run.
  • the plastic pipe of the fender has a thinner wall thickness in the jacket area than in the flange area, the required elasticity of the fender, which can thereby reduce the force of boats or the like, and the required strength of the fastening flanges, which hold the tabs together, are easily obtained and connecting the floating elements allowed.
  • the floating element 1 shown consists of an essentially prismatic hollow body 2, which is produced as a plastic injection-molded part with an open underside 3 and the side walls 4 and the top side 5 along stiffening ribs 6 and two intersecting partition walls 7.
  • the partitions 7 divide the hollow body 2 into four downwardly open chambers 8, whereby according to the exemplary embodiment according to FIGS. 1 and 2, the side walls 4 have a small air hole 9 for each of the chambers, which air holes 9 are arranged at the same distance from the underside 3 .
  • a height measuring scale 10 on the side or partition walls allows not only a simple retrofitting of the air holes 9, but also a reading of the immersion depth of the floating element 1. As indicated in the embodiment according to FIGS.
  • an air hole 9 may be provided, which lead to air holes 9 in the interior of the hollow body 2 on the top wall 5 attached air channels 11.
  • These air channels are arranged in the intersection area of the dividing walls 7 and are created by the dividing walls 7 web walls 12 delimiting them to corner chambers.
  • the air channels 11 extend downward only up to a certain distance above the lower part page 3, where they form inlet openings 13.
  • the underside in order to achieve centering and non-slip positioning when two hollow bodies 2 are placed one on top of the other to increase the floating elements, the underside, as indicated by dash-dotted lines in FIG. 2, can have one of the shape of the top side 5 in the region of the lower end faces of side and partition walls or stiffening ribs with their roundings 14 in the upper edge region or the like.
  • the floating elements 1 can be combined with other identical elements to form platforms 16 or the like, each floating element 1 having connecting parts designed as tabs 17 in the side edge regions. These tabs 17 are offset in height from one another and provided with an eye 18 for receiving a locking bolt 19.
  • the eyes 18 have circumferential indentations 20 for carrying out the corresponding locking cam 21 equipped locking bolt 19 and the lowest tab 17a additionally has on the underside between the indentations 20 locking recesses 22, into which the locking cams 21 of the locking bolt 19 snap when twisted, so that the locking bolt 19 is secured against unwanted pulling out.
  • the floating elements 1 can, as can be seen in particular from FIGS. 3 and 4, be assembled according to the modular principle in the most varied of floor plans, with four adjoining floating elements being connected and locked by means of a common locking bolt 19 which can be inserted and locked through the overlapping tabs of the adjacent floating elements are held together so that platforms 16 or the like are formed in the desired shape and size.
  • a fender 23 can be plugged onto the tabs 17 on these sides and screwed tight, which, as can be seen in FIG. 5, consists of a slotted one Plastic tube 24 with slotted edges angled to mounting flanges 25.
  • the fender 23 is screwed to the tabs 17 via the mounting flanges 25, which have 17 mounting holes 26 at a distance from adjacent tabs, the washers in each case being one Replace the correct knot of four overlapping straps, missing two straps.
  • the plastic tube 24 is thin-walled in the jacket area than in the flange area, so that despite sufficient rigidity for the attachment creates a desired elasticity of the pipe part and the task of a fender can be fully fulfilled.
  • the fender 23 can also be used due to its tubular shape as a supply channel through which water pipes, power lines and the like. Like. Can be laid easily and protected.
  • the surface of the floating elements 1 can be provided with a non-slip profiling and the elements can also be used with other conventional additional devices. Equip and equip.
