Description

[Detailed explanation of the idea] The present invention relates to an offshore connection structure for a floating body.

For example, one method of constructing a large-scale floating structure on the ocean, such as one used as a floating airport, is to connect many floating structures on the ocean.In this case, the floating structure is shaken by wind or waves. Even when the floating bodies are moved, the connections must be made so that there are no gaps between the top surfaces of the connecting parts of each floating body.

In order to satisfy this requirement, a method has been proposed in which all floating bodies are fixed together by means of connection such as welding.

However, with this method, when the floating structure is shaken by wind or waves, for example, the floating structure
In the case where the floating structure is lifted using several supporting points in the longitudinal direction, the weight of the floating structure is most applied to the connection part of the floating structure located near the center of each supporting point,
There was a risk that this connection would be damaged.

The purpose of the present invention is to solve such problems, and the adjacent parts of the upper surface periphery of adjacent floating bodies each have a leg space that is bent downward in the deep part, and the leg space is bent downward. A concave portion with a widening bottom is provided, and an elastic material injected and solidified is inserted between both of these concave portions so that the upper surface thereof is located in the same plane as the upper surface of the floating body. This objective is achieved by providing an offshore connection structure for floating bodies configured to connect the floating bodies through the floating body, thereby creating no gap between the top surfaces of the connecting parts of each floating body under any circumstances. However, it can absorb shocks caused by wind or waves.

The configuration of the present invention will be explained in detail below based on the drawings showing one embodiment thereof.

In FIG. 1, reference numeral 1 denotes a floating structure used as a floating airport, etc. The floating structure 1 is constructed by connecting a number of floating bodies 2, and the floating bodies 2 have a plurality of floating bodies fixedly attached to the lower surface thereof. It floats on the sea surface 4-1 due to the buoyancy of the supporting floating body 3.

An elastic material 5 made of silicone rubber or the like is provided at the connecting portion of the floating body 2.

As shown in detail in FIG. 2, this elastic material 5 is located at adjacent portions of the upper surface peripheries of adjacent floating bodies 2 and is interposed across both recesses partitioned by partition walls 6, 7 and 8. The upper surface thereof is located in the same plane as the upper surface of the floating body 2.

This recess has a downwardly bent leg space in its inner part, and the leg space widens at the bottom.

Further, in the lower half of the elastic member 5, a leg portion 5a is formed between the partition walls 6 and 8 and corresponds to the leg space of the recess, and this leg portion 5a extends from its base end to its lower end. The width gradually increases towards the end.

The elastic material 5 is obtained by injecting and solidifying a liquid elastic material across both of the recesses partitioned by the partition walls 6, 1 and 8, and 9 is an outflow prevention material that prevents the liquid elastic material from flowing out.

The outflow prevention material 9 is made of a material that is easily damaged by the swinging of the floating body 2 after the elastic material 5 has solidified, or a material that has elasticity.

Further, 10 is an outer wall of the floating body 2, and 11 is a surface member made of a material depending on the intended use of the floating body structure 1.

With such a configuration, if the floating structure 1 were to be swayed by wind or waves, the impact such as deflection or tension applied to the connecting portion of the floating body 2 would be absorbed by the elastic deformation of the elastic member 5.

Therefore, there is no possibility that a gap will be formed on the upper surface of the connection part, and there will be no possibility that an extremely large force will be applied to some of the connection parts due to the weight of the floating structure 1, as would be the case if all the floating bodies 2 were fixed together. There is no risk of damage to the connection part.

Further, a leg portion 5a is provided in the lower half of the elastic member 5, and the leg portion 5a is formed so that its width gradually increases from the base end to the lower end, so that the floating body 2 can swing. Therefore, there is no possibility that the elastic material 5 will be pulled out of the recess partitioned by the partition walls 6, 7, and 8.

As described above, according to the present invention, when the floating structure is swayed by wind or waves, the impact applied to the connection parts of the floating structures can be absorbed by the elastic deformation of the elastic material, so that in any case, the upper surface of the connection parts of each floating structure can be absorbed. Although it does not create gaps, it does not cause large forces to be applied to some of the connections due to the weight of the floating structure, unlike when all floating bodies are fixed together, and there is no risk of damage to the connections. It is possible to provide an offshore connection structure for floating bodies.

In fact, since the connection of the floating structure is made at the periphery of the upper surface of the floating structure by injecting and solidifying the elastic material into the recess,
It is easy to construct, and inspection after construction is also easy.In addition, there is a leg space bent downward in the deep part of the floating body at the adjacent part of the upper surface periphery. Since a recess is provided in which the bottom space widens at the bottom, the elastic material injected and solidified into this recess will have its legs widen to correspond to the leg space, and can be tightened using bolts, etc. Even if the floating body is not connected to the floating body, it can be prevented from being pulled out due to the rocking of the floating body.
