Description

APPARATUS FOR CONNECTING CONCRETE BLOCKS OF A FLOATING STRUCTURE IN SEA}

The present invention relates to a device for connecting the blocks constituting the floating structure to each other in the ocean or the lake shore, and more specifically, to a single floating by integrating each other between the adjacent floating blocks constituting the floating structure through the connecting means. It relates to an interblock connection device of a floating structure to behave as a structure.

In general, there are a growing number of cases of using floating bodies as floating structures in the sea. Examples of such floating structures include offshore plants, container terminals, oil storage facilities, offshore tunnels, or offshore parks.

Such a floating structure is generally made of concrete, by connecting and assembling several floating concrete blocks of a rectangular parallelepiped shape having a hollow portion to form a single floating concrete structure.

Such floating concrete structures are made of floating concrete blocks, for example, at a manufacturing site near the coast, and the floating concrete blocks produced by lifting devices such as cranes are launched at sea, and then a plurality of floating There is a method of completing floating concrete structures by connecting and assembling the concrete concrete blocks.

Another conventional technique is to use a floating concrete block in the dry dock (dry dock), this method is mainly used for the production of large vessels, in the dry dock (dry dock) provided on the shore near the coast It is a method of producing floating concrete blocks by making floating concrete blocks and launching the floating concrete blocks by filling the sea water by opening the gate of dry dock.

Meanwhile, another conventional technique is to manufacture a floating concrete block in a floating dock, which manufactures a floating concrete block while floating a pre-fabricated floating dock at sea, and a floating dock. After the floating concrete structures are launched from the sea to connect them to each other and assembled to complete the floating concrete structure.

In this way, the floating structures, each floating in the sea has its own buoyancy, so that they are floating in the sea, and are connected to each other integrally through the connecting devices.

For example, the marine floating structure 1 has a plurality of blocks 10, as shown in FIG. 1A, and these blocks 10 are provided with compartments 12 forming buoyancy spaces therein. Maintain buoyancy.

Such a floating structure (1) has a connecting portion (10a) between the adjacent blocks 10, such a connecting portion (10a) to form a concave hole 14 on both sides of each block (10). And, inserting the steel rods of the tension material 20 to these holes 14, and then introduce a tension force through the fixing device 30 including a nut these blocks 10 are pressed to each other are coupled.

However, the method of integrally connecting the blocks 10 of the floating structure 1 is to simply connect the blocks 10 integrally and integrally with each other, so that when a typhoon or a wave is large at sea, You will not respond properly.

For example, when there is a typhoon or a large blue wave (tsunami, etc.), the floating structure 1 of the sea will be rocked up and down according to the waves. In the conventional integrated floating structure 1, the flexibility is vertically up and down. Since the structure does not have a rocking force transmitted up and down as it is transmitted from the wave, as a result, the load is increased in the block connection portion (10a) has a problem that the connection portion (10a) of the floating structure (10) is damaged Was.

Therefore, in order to effectively resist the typhoon or the big wave, the floating structure 1 further increases the cross-sectional size and height (h ==> H) of the floating structure 1 as shown in FIG. 1B. As a method of increasing the rigidity of the floating structure 10, the connection part 10a of the floating structure 10 should be prevented from damage. In normal) there was a problem that it is very uneconomical to make the floating structure 10 needlessly large.

This is very useful if there is a means (connecting device 100 according to the present invention) that can have a cross-sectional size and height (h) of the conventional floating structure (1) while being able to effectively resist typhoons or large waves. It can be seen that this is a technique to do.

Accordingly, the present invention effectively blocks the typhoon or the big blue wave (tsunami, etc.) to form a more economical and safe floating structure even when the blocks of the floating structure are manufactured and connected to each other with the cross-sectional size and height (h) corresponding to the usual. Was intended.

The present invention to achieve the above object

An apparatus for integrally connecting floating structures at sea,

Hinge connecting unit 130 is connected to each other floating blocks 120 adjacent to each other, the floating block 120 is mounted to be rotatable with each other; And by connecting the floating blocks adjacent to the upper or lower portion of the hinge connection portion, to selectively restrain or allow the (bending) moment so that the entire connection structure of the floating blocks 120 is floating around the hinge connection portion. By using the inter-block connecting device of the floating structure comprising a; variable connecting portion 140 that can be selectively operated to constrain or allow rotational deformation of the formula blocks 120

In use under a small load, the variable connection restrains the (bending) moment of the floating blocks to ensure usability.In the event of a large load such as during a typhoon, the variable connection part allows the (bending) moment of the floating blocks to be hinged. The entire connecting structure consisting of the connecting portion and the variable connecting portion allows rotational deformation of the floating blocks, thereby preventing the structure from being damaged by the (bending) moment.

Preferred variable connector 140 is

A cylinder shaft having both ends mounted on a side of the floating block, a housing configured to provide a space for reciprocating while the cylinder shaft penetrates, and a hydraulic cylinder and a hydraulic pressure adjusting device 200 including pressure oil inside the housing. The hydraulic pressure adjusting device 200 includes a hydraulic pipe 210 connected to the hydraulic cylinder 140 to apply the hydraulic pressure; A hydraulic control unit 220 capable of changing the hydraulic pressure in the hydraulic pipe; And a hydraulic accommodating part 230 having an upper portion for supplying hydraulic pressure to the hydraulic tube.
That is, by releasing the valve which is the hydraulic control part (opening), the hydraulic oil can be moved from the hydraulic cylinder to the hydraulic receiving part so that the pressure oil in the housing is reduced, and the cylinder shaft is pushed in the housing and moved as the cylinder shaft is freely moved. To allow rotational deformation of the equation block,
When the valve which is the hydraulic control unit is blocked (closed), the hydraulic oil cannot be moved from the hydraulic cylinder to the hydraulic receiving unit so that the cylinder shaft restricts the movement and restricts the movement of the blocks connected to the cylinder shaft, thereby disallowing rotational deformation of the floating block. To provide an inter-block connecting device of the floating structure.

In addition, the hydraulic control unit 220 is a valve, when the sudden large load such as a tsunami by acting as an automatic hydraulic pressure adjusting valve or a manual hydraulic pressure adjusting valve to be released automatically when the hydraulic pressure is over a certain amount by an external force. It is possible to prevent the structure from breaking.

In addition to the hinge connecting portion and the variable connecting portion, the auxiliary means is further mounted on the side of the floating blocks to change or adjust the characteristics of the variable connecting portion to improve safety. The auxiliary means includes a spring unit 150 installed on the sides of the floating blocks adjacent to each other, an elastic pad unit 160 fixed to the sides of the floating blocks adjacent to each other, and a damping unit 170 installed on the sides of the floating blocks adjacent to each other. One of them may be installed, or may be configured as a combination of the elastic pad unit, spring unit or damping unit.

According to the inter-block connecting device of the floating structure according to the present invention, since the floating blocks are connected to each other by means of connecting means consisting of a hinge connection part and a variable connection part, the floating structure has an optimized cross-sectional shape, and in general, the connection of blocks. It is structured like a rigid part (rigid connection) to secure usability and to allow rotational movement of the connecting means to secure flexibility in case of typhoon or wave so as to secure both economic efficiency and safety of floating structure. do.

In addition, it is possible to change the characteristics of the variable connection portion by additional auxiliary means and further secure the safety.

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

As shown in FIG. 2, the inter-block connecting device 100 of the floating structure according to the present invention is an apparatus for integrally connecting the blocks 120 of the floating structure having the compartment 122 formed therein at sea. .

The inter-block connecting device 100 of the floating structure according to the present invention is provided with a compartment 122 of a floating space therein to maintain buoyancy, and connect opposite sides of the floating blocks 120 adjacent to each other to Equipped with a hinge connector 130 for allowing rotation, and a variable connector 140 including a hydraulic cylinder to limit or allow the rotational deformation between the floating blocks by the hinge connector, and the hinge connector In addition to the variable connection portion, the auxiliary means (150, 160, 170) mounted on the opposite side of the floating block 120 is mounted.

As shown in FIG. 2 and FIG. 3, the hinge connection unit 130 includes the holes 132a of the hinge frames 132 installed on the side surfaces of the floating blocks 120 adjacent to each other, respectively, as the hinge pins 134. By connecting to allow rotation between the adjacent floating block 120, but has a function to block the displacement in the vertical and horizontal directions.

Such a hinge frame 132 is formed integrally during the concrete placing of the block 120, a fixed plate 136 is formed on one side, a plurality of anchor members 138 formed on the fixed plate 136 block 120 It is integrally installed on one side of the.

And the hinge frame 132 is a hinge pin 134 is inserted through the hole 132a formed in the center, respectively, such a hinge pin 134 of the vertical block between the floating block 120 adjacent to each other It is to connect the single floating structure by integrating the floating blocks 120 with each other while blocking the transmission of (bending) moment without displacement.

At this time, the hinge connector 130 has a connection function that does not restrain the rotation of the floating block 120, so if there is a typhoon or a large blue (tsunami, etc.) in the process of rotating while the floating block 120 is constrained with each other Since the cross-sectional force generated by a typhoon or a large wave (tsunami, etc.) can be reduced, a smaller cross-sectional size and height can be reduced without increasing the cross-sectional size and height of the floating blocks (h ==> H) as shown in FIG. The advantage is that the floating block can be manufactured and installed.

In other words, when the floating blocks are rigidly connected by a typhoon or a big wave (tsunami, etc.), the rotation between the floating blocks is constrained, and a large (bending) moment is generated in the floating blocks, but if the rotation is not constrained (bending) Since the moment is not generated in the floating blocks, the cross-sectional force (bending moment) of the floating blocks generated by the typhoon or the big wave (tsunami, etc.) can be reduced.

However, when the floating blocks 120 are simply connected by the hinge connector 130, the rotation of the blocks is not restricted even when the typhoon or the big blue (tsunami, etc.) are normally constrained by the somewhat weaker waves. 120) are somewhat rumbled. This rocking will eventually affect the usability of the floating structure.

Therefore, in addition to the hinge connector 130, it is necessary to improve the usability, such as floating structure floating by the wave in a way that the floating blocks 120 are rigidly connected to each other.

It is the variable connection portion 140 of the present invention that plays a role in this, which selectively operates so that the entire connection structure of the floating blocks 120 constrains or permits rotational deformation of the floating blocks 120 about the hinge connection. It is configured to be.

That is, the meaning of the variable connection portion is to have a rigid connection function in normal to restrain the rotational deformation of the floating block by the hinge connection portion so that the floating block 120 does not slack,

When a typhoon or a big blue (tsunami, etc.) occurs, it means that the rigid coupling function is released so that the hinge coupling function is performed. In other words, the rigid coupling function and the hinge coupling function are switched simultaneously.

In order to implement a switching function at the same time for the rigid connection and the hinge connection function, the variable connection unit 140 may be composed of a hydraulic cylinder 140a and a hydraulic control device 200, for example.

That is, the hydraulic cylinder 140a and the hydraulic control device 200, which are variable connection parts 140, are mounted on adjacent portions of the hinge connection part 130 respectively installed on the side surfaces of the floating blocks 120 adjacent to each other.

The hydraulic cylinder 140a is composed of a cylinder shaft having both ends mounted on the side of the floating block 120, a housing providing a space for reciprocating while the cylinder shaft penetrates, and a pressure oil inside the housing.

When the movement of the hydraulic oil inside the housing is limited (this is to close the valve as a hydraulic control unit 220 to be described later to limit the movement of the hydraulic oil. See the enlarged view on the right side of Figure 2) ), So that the blocks are rigidly connected to each other, such as to be connected to each other by steel rods.

If the movement of the pressure oil is not restrained (this is to open the valve as the hydraulic control unit 220 to be described later to allow the movement of the pressure oil. Refer to the enlarged view on the left side of FIG. 2). It can be seen that the reciprocating movement to allow the rotational deformation of the floating blocks 120 to eventually control the movement of the hydraulic fluid to be able to variably allow or constrain the rotation of the entire connection.

Therefore, the present invention uses the floating blocks having the cross-sectional size and height (h) that can be applied to the usual, as usual, the variable connection portion 140 so that the (bending) moment of the hinge connection 130 is transmitted between the blocks. By restricting the movement of the hydraulic oil in the hydraulic cylinder by the, so as not to be affected by the usability, such as slacking,

If a typhoon or a large blue (tsunami, etc.) occurs, the hydraulic pressure is constantly maintained (closes the valve by the hydraulic pressure adjuster) by the variable connection portion 140 by allowing the movement of the hydraulic oil in the hydraulic cylinder to the hinge connection portion The entire connecting part consisting of the variable connecting part can reduce the cross-sectional force of the structure by preventing the (bending) moment from being transmitted between the blocks.

At this time, the means for limiting or allowing the movement of the pressure oil is the hydraulic pressure control device (200). That is, the oil pressure adjusting device 200 has a function to selectively adjust the movement of the pressure oil inside the hydraulic cylinder, which is a variable connection unit 140 as needed.

The hydraulic pressure adjusting device 200 includes a hydraulic pipe 210 connected to the hydraulic cylinder 140 to apply hydraulic pressure; A hydraulic control unit 220 capable of changing the hydraulic pressure in the hydraulic pipe; And a hydraulic accommodating part 230 having an upper portion for supplying hydraulic pressure to the hydraulic tube.

The hydraulic pipe 210 is a pipe through which pressure oil (fluid accommodated in the hydraulic cylinder) flows, one end of which is connected to the housing of the hydraulic cylinder, and the other end of the hydraulic receiving part 230, which is an upper pressure oil tank in which a kind of pressure oil is received. ) Accordingly, the hydraulic control unit 220 having a function of controlling (limiting or allowing) the movement of the hydraulic oil from the hydraulic accommodation unit 230 to the housing is implemented as a valve.

That is, by releasing the valve which is the hydraulic control unit 220 (open), the hydraulic oil may be moved from the hydraulic cylinder which is the variable connection unit 140 to the hydraulic receiving unit 230, thereby reducing the pressure oil inside the housing and thus the cylinder shaft. As the cylinder shaft moves freely as it is pushed inside the housing, it allows rotational deformation of the floating block (so that the (bending) moment of the hinge connection is not transmitted between the blocks).

Blocking the valve, which is the hydraulic control unit 220 (closed), since the hydraulic oil cannot be moved from the hydraulic cylinder to the hydraulic accommodating unit 230, while the cylinder shaft restricts the movement to limit the movement of the blocks connected to the cylinder shaft. Rotational deformation of the floating block is tolerated (allowing the (bending) moment of the hinge connection to be transmitted between the blocks).

At this time, the movement or restriction of the hydraulic oil may be manually performed at that time by a manpower (manual hydraulic pressure regulating valve), but even if a rapid response is difficult, even if it is predicted like a tsunami, automatic adjustment is possible. It is necessary to.

Of course, the automatic supply of pressure oil may be complicated and expensive automatic adjustment means may be used, but this means an increase in cost. It is preferable to enable a simple automatic pressure oil supply in such a way as to open (not shown), the configuration of the valve for automatic pressure oil supply in the present invention will be able to use a valve capable of automatic closing can be used conventionally.

Furthermore, a configuration may be adopted in which the valve is automatically released when the hydraulic pressure becomes higher than a certain amount due to external force.

In addition, a plurality of spring units 150 may be added to the basic configuration to connect side surfaces of the floating blocks 120 adjacent to each other as a control means of (bending) moment transmission.

That is, the spring unit 150 may play a role of partially transferring the (bending) moment when the hydraulic pressure of the variable connection part is released and the hinge connection part and the variable connection part according to the present invention are fully hinged. As the stiffness of the spring unit increases, the transfer amount of (bending) moment increases, so it is closer to the rigid connection. As the stiffness of the spring unit decreases, the transfer amount of (bending) moment decreases. Will work.

 The spring unit 150 may be installed so that both ends of the spring is fixed to the side of the floating block 120 adjacent to each other.

In addition, the floating blocks integrated by being connected to each other by the hinge connection unit 130 and the variable connection unit 140 as described above may be damaged by hitting each other while causing rotation and position displacement (rotation). Means for preventing is the elastic pad unit 160 of the present invention. That is, as shown in Figure 5 is fixed to the side edges of the floating block 120 adjacent to each other.

As the elastic pad unit 160, the elastic pad is made of a foamed plastic material or a rubber material having excellent elasticity and resilience, and the distance d between the blocks 120 is too narrow to be disposed between the side surfaces of the blocks that are to collide with each other. Also, the adjacent blocks 120 can be prevented from being damaged when they are moved by the waves and collide with each other, thereby acting as a means for supporting the function of the connection device according to the present invention (prevention of damage).

Next, the damping unit 170 is fixed to the side edges of the floating block 120 adjacent to each other as an energy dissipation means as shown in FIG.

As the damping unit 170, the damper has a similar shape to the hydraulic cylinder, but its operation is completely different, and the hydraulic pressure inside the hydraulic cylinder as a variable connection part basically maintains the amount thereof without additional hydraulic control device 200. In other words, since there is no change in the internal hydraulic pressure of the hydraulic cylinder, the movement of the cylinder shaft constituting the hydraulic cylinder is inevitably limited.

The damper can be passed through the cylinder shaft end plate through the cylinder shaft in the housing so that the cylinder shaft is reciprocating movement of the cylinder shaft in the housing when the space between the blocks change due to the wave, etc. It has a function of absorbing and has a kind of energy dissipation function.

That is, the damping unit 170 has a secondary function that can prevent the occurrence of excessive hydraulic pressure in the variable connection portion in the connection device according to the present invention.

Meanwhile, the inter-block connection device 100 of the floating structure according to the present invention may be installed in combination with each other on the side of the floating block 120 adjacent to the auxiliary means (150, 160, 170).

For example, by combining the respective features of the spring unit 150, elastic pad unit 160 and damping unit 170, adjacent blocks 120 can more effectively respond to external forces caused by waves and the like.

In addition, the adjacent floating blocks 120 are mounted on a side thereof with a sheath 180 so as to surround the hinge unit 130, the variable connector 140, and the auxiliary unit, for example, the spring unit 150. The sheath 180 may have a structure in which an edge thereof is fixed to each side of the floating block 120.

The sheath 180 may be made of a flexible rubber material, or may be made of a sheet material in which wrinkles are formed. Such a sheath 180 surrounds the hinge connector 130, the variable connector 140 and the auxiliary means so as not to be exposed to the outside. Through this, the hinge connector 130, the variable connector 140, and the auxiliary means 150 are protected from external shock and are not damaged.

The inter-block connecting device 100 of the floating structure according to the present invention configured as described above through the hinge connecting portion 130, the variable connecting portion 140, the auxiliary means (150, 160, 170) between the adjacent floating blocks 120 Block (120) can be integrated through the hinge connection and rigid connection with each other while blocking and allowing (bending) moment transmission.

In addition, the hinge connector 130, the variable connector 140, the auxiliary means (150, 160, 170) is preferably to be installed on the top or / and bottom of the side between the blocks, it is not excluded to be installed in other positions The installation location, the number of installation and the combination method may be optional according to the designer.

The protection scope of the present invention is limited only by the matters described in the claims, and those skilled in the art can change and change the technical idea of the present invention in various forms.
