Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting device for controlling the spacing and movement between structures of a floating structure or a gravity type K hand,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a connecting device for controlling the spacing and movement between structures of a floating structure or a gravity type K hand, and a connecting method using the connecting device and a large-sized floating structure such as a gravity type K- For more than 100 years, it is necessary to maintain the spacing between large floating structures in a stable state without the use of metal for safe use, to improve the separation between structures of floating structures or gravity type And a connection method using the same.

In the ocean, a large floating structure must be constructed to be connected to an articulated joint, which can not be built solidly, and whose force and moment are difficult to transfer. In order to maintain the overall shape of the structure and to withstand the external forces It shall be held in a soft / refracting connection structure.

When a large floating structure is to be connected, for example, 100mBx150mLx40mD = weight of 50,000ton of concrete can not be lifted up and down without using buoyancy when connecting dozens, hundreds or thousands of weight, (Tug Boats) can be used to move slightly in the lateral direction. In this state, it is usually possible to use a ballard to hold anchor, wire or rope, prevent collision with each other, It is common to use tires or similar fenders.

For example, in the case of the registered patent application No. 1131423 filed by the applicant of the present invention, the sea current transmission type breakwaters are restrained in a state of being bound together by anchor chains, and rubber fenders are arranged on the faces facing each other, (Snake type), so that even when the impact energy is applied to the current transmission type breakwater by the current or the wave, it is configured to absorb the impact energy while being deformed like a snake.

However, since anchor chains and the like are metals, they have a very long life, for example, more than 100 years.

In addition, the US Coast Guard Engineering Center, which covers the entire literature and status of floating breakwaters around the world, has been using metals to prevent collisions between breakwaters even in 1981, It is almost unprecedented to treat metal-free connectors (see, for example, Hales, Lyndell Z .: Floating Breakwaters: State-of-the-Art Literature Review, Technical Report No. 81-1, October 1981, US Army, Corps of Engineers, Coastal Engineering Research Center, Kingman Building, Fort Belvoir, Va., 22060, USA, pp. 279).

Patent No. 1096094 is disclosed as an example in which no metal is used. However, in the case of the above-mentioned Patent No. 1096094, it is preferable that no metal is used, but it is preferable that the clearance is controlled in a single direction, , It is possible to control the direction perpendicular to the longitudinal direction, which is the same direction as the incident angle of the wave, which is the greatest external force. However, no other external force generated in the sea, that is, a clearance control for a force acting in the other direction is not described It has structural limitations.

In addition, when the external force in the longitudinal direction is very large, the force and the variation in the longitudinal direction are not controlled, which may cause structural safety problems.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

The connection device that controls the separation and movement of the floating structure or the gravity type K hand structure of the sea is very long when the floating structures are interconnected in the gravity type K hand etc. as well as the floating breakwater installed for the purpose of securing the warm water area, For example, in order to be usable for more than 100 years, the metal connecting means (anchor, wire, etc.) should not be used, but the present invention is configured to realize this.

When connecting very large floating structures at sea, it is necessary to maintain mutual clearance to prevent individual structures from colliding with each other due to blue and storm.

In addition, when it is necessary to separate floating marine floating structures from the marine vessel for the purpose of repairing, the connecting device according to the present invention is easy to separate and disassemble, so that large floating marine floating structures can be easily separated.

In particular, it is very difficult to connect the connecting devices with the floating floating structures floating, which means that forcing the gap-retaining member into the gap between the floating structures to maintain the spacing is very large, for example, Structures can not be pushed out, requiring considerable difficulty and hard work.

However, the connecting device according to the present invention has a merit that the floating structures can be easily and quickly installed without difficulty by naturally fitting and fixing the floating structures with each other even if they are simply fitted on the upper part.

However, if you do not use metal in the connection device for a very long time, for example over 100 years, and almost permanently, you can not simply change the material. This is because large floating structures are floating on water rather than fixed at a specific location, such as on land. For example, floating structures in the sea can be lifted by buoyancy, heaving, pitching, roll and sway Sway), as well as the phase difference due to the motion between the floating structures.

For this reason, the force and the movement are transmitted and dispersed only when they are held together, so that the aggregate of the whole structure can be stabilized. Therefore, it is preferable that the connecting device is controllable from a complete coupling in which no relative movement is allowed to a slightly loosely connected one. However, in the present invention, a small gap is provided between the solid structures, To achieve such loosening of the degree of connection.

1 to 3, the connecting device according to the present invention includes a connecting ring 100 and a wedge 200. As shown in FIG.

At this time, the connection ring 100 and the wedge 200 should be formed of a material other than a metal, and various types of the connection ring 100 and the wedge 200 may be used, but preferred examples thereof include Teflon and silicone.

Particularly, the most significant feature of the present invention is that, for example, a large-scale floating structure 300 with more than 50,000 tons should be connected for at least 100 years, and therefore the metal flow must be excluded.

In addition, the connecting device according to the present invention is also characterized in that it is configured to be able to cope with various external forces generated in the sea by inducing a loose connection, not a tight connection. This is because it is possible to maintain the clearance in the longitudinal direction as well as the direction perpendicular to the longitudinal direction beyond the features of the existing technologies in which the clearance is controlled only in the direction perpendicular to the longitudinal direction of the large-scale floating structure 300, Including the concept of control.

In the connecting device according to the present invention, the annular groove 310 is formed on the slope of the large-scale floating structure 300 for the connection ring 100.

For example, referring to FIG. 3, a ring installation groove 310 having a shape facing each other is provided on a side where the large-sized floating structure 300 and the adjacent large-size floating structure 300 'face each other.

In addition, the coupling ring 100 is inserted into the ring mounting groove 310.

In this case, it is easy to understand that the connection ring 100 is not a metal as described above, but is assembled in a form of assembling a kind of a lEGO block.

At this time, it is preferable that the annular groove 310 has a substantially trapezoidal flat cross-section, and the connecting ring 100 is not fitted in the annular groove 310, but has a loose coupling .

In addition, the wedge 200 is inserted into the upper portion of the connection ring 100 to surround the connection ring 100.

The wedge 200 has a substantially "∩" shape, and both ends have a wedge shape, that is, a sharp "V" shape toward the bottom.

The reason for wedge-shaped both ends of the wedge 200 is that, as described above, the gap between the large-size floating structure 300 and the adjacent large-size floating structure 300 ', which are larger than 50,000 tons, So that the large-scale floating structures 300 can be naturally lowered and fitted as they move along with the movement of seawater even if they are slightly wedged in the upper part.

That is, according to the present invention, there is no need to forcibly insert the device into the device, and the device is configured to simply drop the device on the device, and then automatically lower the device while inserting the device.

A method of connecting large floating floating structures 300 using such a coupling device is as follows. First, a first step of vertically forming a trapezoidal ring installation groove 310 on a slope of a large floating floating structure 300 is performed do.

When the annular groove 310 is formed through the first step, a second step of floating and arranging the large-sized floating structure 300 on the sea is performed.

Thereafter, a third step of binding the plurality of large-scale floating structures 300 to each other is performed by inserting the coupling ring 100 into the ring installation groove 310.

When the third step is completed, the wedge-shaped lower end of the wedge 200 is inserted into the spacing space between the large-sized floating structures 300 while the wedge-shaped bottom end of the wedge 200 is inserted in the width direction of the connection ring 100 The wedge-shaped lower end of the wedge 200 is completely inserted into the wedge-shaped lower end of the wedge 200 as the large-scale floating structures 300 are moved in accordance with the flow of seawater, .

By doing so, it is possible to maintain a constant degree of mutual separation while buffering the flow in the longitudinal direction as well as the flow in the width direction of the large-scale floating structure 300.

Particularly, since the wedge 200 is easy to separate, the wedge 200 can be separated from the large floating structure 300 only by lifting the wing 200 separately.

In addition, the connection hook 100 is not inserted and fixed so as to be completely tightly fitted to the ring installation groove 310, but retains a loose connection constraint state with a slight clearance, So that the flow of the adsorbent can be absorbed and buffered sufficiently and stably.
