Definitions

• the invention relates to a floating body for use as a floating dock, bathing island, boat dock or the like, consisting of a body to be anchored floating in the water.
• Known floating jetties, jetties or the like generally consist of wood, which are either made buoyant by buoyancy barrels or are firmly anchored to the water bed. Such constructions are also used as swimming islands in swimming pools or in lakes. The local positioning is done on floating docks by anchoring or by means of steel cables, chains or the like.
• the known devices have the disadvantage that both the wood material and the additional buoyancy elements are subjected to severe wear due to weather conditions and the water. This applies in particular to firmly anchored webs with fluctuating water levels. Accordingly, such floating bodies rot in a relatively short time or they become unsightly very quickly.
• the invention has for its object to provide a floating body which does not have the disadvantages described and which is inexpensive and technically simple to manufacture.
• the invention has the advantage over the known floating jetties, jetties, bathing jetties, etc. that a working device was created by means of largely rotting-resistant materials, which can be easily and inexpensively manufactured with flat outer surfaces and is largely insensitive to environmental influences with regard to its service life .
• a shapely design is achieved by the smooth outer surfaces and the risk of injury or damage is also reduced. Due to the large mass, such floating jetties are still in the water even when the waves are swell.
• the invention is based on the known finding that the total weight of the floating body, including the load on it, is equal to the weight of the amount of liquid displaced. From this technical context, the given external dimensions of the float Calculate immersion depth very precisely. In addition, the immersion depth can be increased by additional weights, e.g. B. also increased by additional lightweight concrete or reduced by additional buoyancy.
• the floating body according to the invention is therefore suitable for the most precise laying of such floating docks, bath islands, etc.
• the subclaims provide for further measures to achieve the object according to the invention or for advantageous further training and improvement of the object according to the invention.
• a rigid foam for. B. Styrofoam o. Like. Used, which is welded into a waterproof plastic film.
• the plastic film is recommended because the lightweight concrete shell cannot completely strip the hard foam buoyancy body from the water.
• a buoyancy body made of rigid foam a polyester container filled with air can also be used.
• the polyester shell can be made completely watertight, so that a rot-free floating body is also created here.
• other buoyancy bodies made of other materials can also be used, provided they are suitable as buoyancy bodies.
• the total weight of the floating body is selected such that, with given external dimensions, the immersed volume of the floating body corresponds to approximately 2/3 of the total volume.
• This advantageous embodiment causes 2/3 of the floating dock to be immersed, while 1/3 projects above the water surface.
• it is provided that these can be connected to one another via a type of piano hinge. This has the advantage that the individual floating bodies can swing up and down against each other during waves and do not represent a rigid structure. As a result, the durability of such webs is significantly improved.
• Fig. 2 is a compilation of several floating docks in plan view
• Fig. 3 shows the type of connection between two floating docks.
• the floating body 10 shown in FIG. 1 is constructed as a cuboid 11.
• the floating body 10 consists of an inner buoyancy body 12 which is designed as a rigid foam body in FIG. 1. When using rigid foam, it is enclosed by a waterproof plastic film 13 so that no water can penetrate into the rigid foam.
• the outer shell of the floating body 10 is formed by a lightweight concrete jacket 14, which the buoyancy body fully constantly surrounds.
• the Lei ⁇ htbetonhülle 14 consists of a concrete with light aggregates as it is known under the name expanded clay or pumice, foam concrete.
• the density of this lightweight concrete can be set between 1.0 to 1.5 g / cm 3 . In this way, the weight of the floating body can also be influenced.
• the thickness of the lightweight concrete cover is about 5 - 15 cm. To adjust the draft of the floating dock, the weight can be varied through the lightweight concrete cover, which in turn depends on the shape of the floating body.
• the lightweight concrete casing 14 has a shoulder 16, ie. H. the concrete shell normally protrudes beyond the base body. This shoulder serves as a contact edge or fastening edge for further floating bodies and gives it a certain freedom of movement.
• Fig. 1 the water surface is shown schematically at 17.
• FIG. 2 several floating bodies 10 are connected to one another via hinges 18.
• These hinges 18 are constructed in the manner of a piano hinge, as shown in Fig. 3.
• tube sections 20 are alternately welded to two flat steel irons 19 with respect to the longitudinal direction of the hinge.
• the weld seams are shown schematically at 21.
• An inner round rod 22 then connects the individual pipe sections and assembles the joint.
• the hinge is anchored in the lightweight concrete by means of screws or bolts 23.
• brackets 24 are further anchored laterally, which serve to receive fastening piles 25 which are rammed into the ground 26.
• the floating jetty can move up and down in waves or water level fluctuations without changing its position in the rest.
