Definitions

• the invention relates to a buoyant structure for carrying loads as a rigid unit, and more particularly to such a structure composed of buoyant individual bodies connected to elongated connecting means having cavities.
• Floatable structures according to the invention can be used for a variety of applications, e.g. Loads such as roads, houses, movable structures, gardens, terraces and objects hung beneath the structures, such as liquid containers, pipes and walk-in submarine space for marine life observation.
• Loads such as roads, houses, movable structures, gardens, terraces and objects hung beneath the structures, such as liquid containers, pipes and walk-in submarine space for marine life observation.
• a floating foundation is known from the prior art as a rigid platform.
• the invention is based on the object to develop a frictional connection of concrete floating bodies with Styrofoam insert or other floating basic elements with the aim to produce floating foundations as a supporting, rigid platform for receiving different sized loads.
• This object is achieved by reinforced concrete floating body with Styrofoam insert, which are arbitrarily assembled depending on the structural design, existing recesses in the webs by means of reinforced concrete beams in place in the water, so that different sized loads can be transferred to the floating foundation.
• a disadvantage of such a known floating foundation is that an elongate foundation either has a relatively low torsional rigidity. or its production is associated with relatively high material costs. Furthermore, it is disadvantageous that the construction of the known foundation is not suitable for approximating any shapes, in particular rounded shapes.
• a buoyant structure is formed as a rigid unit of a plurality of buoyant individual bodies, wherein the buoyant individual bodies are each provided with one or more elongated recesses. These recesses are preferably provided in the same direction in which the structure has its greatest extent. In the recesses elongate connecting means are inserted, which connects at least two of the buoyant individual body with each other.
• the connecting means according to the present invention may have suitable profiles, for example a box profile or a triangular hollow profile or a honeycomb-like profile.
• a box section made of reinforced concrete can advantageously be used as a connecting means.
• Such a box profile not only allows the saving of material and thus reduces costs, but it also leads to a weight reduction. Low weight is of great importance, especially for buoyant structures. tung.
• further struts can be provided inside the profile.
• the cavities of the connecting means according to the invention offer the possibility of using the same with lightweight, buoyant materials, e.g. Fill in styrofoam.
• Internal flotation bodies may also be interior linings of non-corrosive material such as e.g. Plastic material, to be used.
• a box profile made of plastic material can be introduced, which can optionally be closed at its ends, thus creating a water-protected space that can accommodate other equipment. This avoids that in the case of leaks in the outer wall larger amounts of water can accumulate in the interior of the connecting means.
• the same also applies to the buoyant single bodies.
• the cavities of the connecting means may also be used to supply supplies such as e.g. Pipes or cables. In conjunction with openings in the top of the box profiles so homes or other facilities can be supplied on the buoyant structure.
• supplies such as e.g. Pipes or cables.
• Reinforced concrete is treated with reinforcement overlays to protect against corrosion, which are above 1, 5 cm, usually in the range of 2 cm to 5 cm.
• the water composition must also be taken into account in buoyant structures.
• buoyant structures an overlap of 4.5 cm or more is usually used.
• Carbon fibers or glass fiber materials can be used according to the invention for the connecting means.
• textile-reinforced concrete in contrast to reinforced concrete, there is no risk of corrosion. As a result, it is also possible to work with significantly lower probation coverage. This leads to lighter constructions and more efficient use of materials.
• a plurality, in particular four, mutually parallel connecting elements can be used.
• the exact arrangement or orientation of the recesses in which the connecting means are introduced depends on the geometry and the requirements of the buoyant structure. Constructions are also conceivable in which connecting means do not run parallel to one another. If a plurality of connecting means are used, they can, according to the requirements of the buoyant structure, consist of different materials and / or have different profiles / dimensions.
• the connecting means extend over the entire length of the structure, as a result of which the structural unit of the rigid structure is ensured in an advantageous manner.
• the walls of the floatable individual bodies may contain carbon fiber or glass fiber materials just like the connecting means.
• floating single bodies are used which, in plan view, have a shape substantially corresponding to the shape of an equilateral triangle.
• the floating single body preferably has the shape of a straight prism with the base of an equilateral triangle.
• the element floats, its surface is parallel to the water surface. This is essential for a buoyant structure. For example, would you use a non-equilateral triangle and no special ones Take precautions with regard to the weight distribution, the surface of the buoyant body would not be parallel to the water surface.
• equilateral triangles lies in the fact that they can be composed of larger structures without gaps. Any outlines of buoyant structures can be easily approximated. However, desired areas may also be left blank, e.g. To clear rooms for obstacles or building elements such as columns.
• Profiled walls showing profiles as described above can be used.
• the cavities of the profiles can be filled with Styrofoam.
• a uniform covering layer is applied over a plurality of individual bodies, this being advantageous for the rigid connection of the individual bodies.
• a sealing bottom plate protects the interior of the single body from water and damage, but is not absolutely necessary.
• the interior of the single body is filled with Styrofoam or other buoyant material.

• vibrations of the structure which are caused for example by waves, can be efficiently reduced.
