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 for example known from AT-Psen 312 039 and 325 094, 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 their worth due to their diverse range of applications. 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.
  • the invention is therefore based on the object to remedy these defects and to provide a floating element of the type described, which ensures the assembly of a particularly stable, quiet and safe lying on the water or the like with little effort, light weight and skillful handling .
  • the plastic hollow body has an open underside in a manner known per se and at least one air hole is provided in the walls at a distance from the underside.
  • 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 also only vent slowly when the waves are blowing and the air hole is released Tet, which ensures a quiet location largely unaffected by the waves. 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 at least one partition into downwardly open chambers 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
  • four chambers are advantageously prepared by two intersecting partitions, each having the air hole in one of its outer walls.
  • internal chambers are provided, which are only delimited by partitions, these chambers are connected to the neighboring chambers by their air holes or they can also be ventilated through the upper side, but this does away with their contribution as a buoyancy chamber.
  • At least one wall has a height measuring scale for the subsequent placement 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 chambers can also be inserted after the Floating and venting floating elements as required and the immersion depth of the elements remains adjustable. It is possible to connect the existing air holes with air lines to a common, central valve or to provide each air hole with its own valve, the height of the air holes being of minor importance, but will be chosen so that if the valves fail an immersion limit of the elements cannot be exceeded.
  • the interior of the hollow body takes at least one air duct or the like that runs in height. on which air ducts form inlet openings at a distance above the underside and into which the air holes lead at a distance above the inlet openings.
  • the immersion depth is no longer determined by the height of the air holes, but by the position of the inlet openings in the air channels, which are in constant communication with the outside air even through the air holes.
  • 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 channels.
  • the air channels are attached to the top wall of the hollow body, in which the air holes are also located, since the hollow bodies can be produced easily and without difficulty despite the air channels the overhead air holes or the like through adjacent floating elements. cannot be installed or even locked, which would impair the ventilation.
  • each chamber is provided with an air channel, wherein corner chambers delimited by web walls in the corner regions of vertical inner wall edges preferably form these air channels.
  • the water cushions in the individual chambers counteract mutual level differences and make tilting movements of the floating element more difficult.
  • the air ducts can be made in and of themselves in any way, for example by gluing plastic pipes or the like, but corner chambers are particularly well suited for this purpose, since the air ducts are produced practically without additional effort in the course of hollow body production, for example in the injection molding process, the web walls of the air channels bring additional stiffening of the hollow body or the partition walls with them.
  • 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 underside end faces of the side and partition walls and any stiffening ribs that may be present have a shape that is adapted to the rounding of the top, the elements are mutually centered and positionally positioned.
  • a fender which consists of a longitudinally slotted plastic tube forming slot edges angled outward to fastening flanges, can be plugged horizontally onto 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 consistently firm floating element connection is also created in the edge area of the platform.
  • the fender 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 bottom 3 and the side walls 4 and the top 5 along stiffening ribs 6 and two intersecting partitions 7.
  • the partitions 7 subdivide 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.
  • air holes 9 can 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.
  • air channels 11 are arranged in the intersection area of the dividing walls 7 and are created by the dividing walls 7 web walls 12 which delimit 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 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 each other 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 latching 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 being pulled out undesirably.
  • 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 down, as shown in FIG. 5, from 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 proper 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 profile and that the elements can also be used with other conventional additional devices. Equip and equip.
