Description

FIELD OF THE INVENTION [0001] The present invention relates to a buoyant body for floating structures,

The present invention relates to a buoyant body for a floating structure and a method of manufacturing the same. More specifically, the present invention relates to a buoyant body for a floating floating structure that is more economical and stable because a large-scale floating structure can be stably installed in the sea, and a manufacturing method thereof.

1A is a perspective view of a conventional floating dock (Patent No. 10-1302037).

That is, the hull unit 10 includes at least one hollow hole portion 14 penetrating the deck and the bottom of the ship.

A plurality of ballast tanks (20) disposed in the hull portion; And

And a pumping unit installed in the hull unit for supplying seawater to the plurality of ballast tanks or discharging seawater supplied to the plurality of ballast tanks,

The pumping unit (30, 40) is installed in the hull portion, and seawater is discharged from the bottom of the hull portion along the hollow hole portion (14) passing through the ballast tank adjacent to the central portion of the hull portion A first pumping unit (30) for discharging the seawater supplied to or supplied to the ballast tank adjacent to a central portion of the plurality of ballast tanks; And a second pumping unit (40) installed in the hull unit for supplying seawater from the outside of the hull unit to the ballast tank adjacent to the outer periphery of the hull unit among the plurality of ballast tanks or for discharging the supplied seawater .

In other words, the dock for making the ship is formed as a floating dock. The floating dock is mounted on the floating dock after making the large blocks close to the maximum capacity of the crane on the land, , The seawater is supplied to the ballast tanks of the floating dock to submerge the floating dock below the sea level, and then the completed ship is launched,

Particularly, it is possible to reduce the movement path of seawater by supplying seawater to ballast tanks or discharging seawater from ballast tanks through a hollow hole (14) penetrating the deck and bottom of hull, and to precisely control the amount of seawater So that a stable floating dock can be installed at sea.

As a result, most of the ballast tanks are constructed to be a structure that is advantageous for algae and waves due to seawater in order to construct a ship from a floating dock. Mostly, due to the weight of the ship, ballast tank control of floating dock made of concrete or steel The focus is focused on.

FIG. 1B shows a construction diagram of a conventional floating floating pension structure (Patent Laid-Open Publication No. 10-0056407).

That is, a house 51 that provides a space where a person can live, a top plate 53 that supports the house 51 and is provided with buoyancy but is formed of a plurality of plates 52 on the upper surface, A water house formed by an extension plate 56 which can be retracted between the upper plate 53 and the frame 55 and which includes a supporting portion constituted by a hexahedral frame 55 provided with a plurality of buckets 54, .

In other words, it can be seen that the houses 51 can support the weight of the water houses through the holes 54 provided in the frame 55.

Therefore, it is possible to easily secure the buoyancy of the float to support the water house and to adjust the buoyancy by separately installing a ballast tank in the frame.

However, the above water houses are not so large in weight, and a large-sized concrete structure can be directly applied to the float, but there is no specific description about the prefabricated float which is easy to construct. Especially, the integration of the float and the concrete structure The means for this has not been otherwise disclosed. That is, if the large concrete structure and the floating body are not integrated with each other, there is a limit to securing stability only by the ballast tanks before and after the construction.

Accordingly, the present invention provides a float capable of stably constructing a reinforced concrete structure in a river or sea, and can serve as an efficient ballast tank without a large weight, and can be used as a floating ballast structure The present invention provides a buoyant structure for a floating structure that is structurally safe.

To this end,

The buoyant body for a floating structure according to the present invention makes a buoyant buoyant structure for a floating structure by making and connecting a temporary buoyant body. These hypothetical buoyant bodies can be fabricated as segmented buoyant bodies for easy connection at sea and buoyant bodies for sea floating structure construction by connecting them at sea.

In this case, since the floating structure in the sea is made of cast-in-place concrete, a formwork is required. Such a formwork is installed in the assembling and building buoyancy body, and in constructing the concrete, the assembled construction buoyant body and the concrete, So that the on-site cast concrete connection material is integrally formed on the body surface.

The buoyant body for the floating structure in which the assembly suspended buoyant body according to the present invention and the poured concrete are integrated with each other can further serve as a diverging plate for various floating structures in the upper portion. The buoyant body for the floating structure, It is possible to adjust the balance in waves and adjust the eccentric load due to the construction of the floating structure in the freeway so that it is possible to provide the buoyant structure for the floating structure in which the floating floating structure can be constructed more quickly and economically, do.

[Buoyancy body for floating structure (A)]

FIG. 2A is a perspective view of a buoyant body A for a floating structure according to the present invention, and FIGS. 2B and 2C are views showing a configuration of a buoyant buoyancy body 100 constituting a buoyant body A for a floating structure according to the present invention. FIG.

The buoyant body A for the floating structure is formed to include the assembled temporary buoyant body 100 and the field mounted base plate 200 in which the spotted concrete connection members 113 are integrally formed as shown in FIG.

As shown in FIG. 2B, the assembling and building buoyant body 100 is assembled to a desired size by assembling a plurality of segmented buoyant bodies 110 and assembling them together in a sea (meaning river or sea).

The segmented buoyant body 110 includes a hypothetical buoyant body 111 and a ballast control pipe 112, both of which are made of a cuboid body.

First, as shown in FIG. 2C, the hypothetical buoyant body 111 in the form of a flat plate box body is a box body formed of a bottom plate 111a, a side plate 111b and an upper plate 111c having a constant thickness. It can be seen that the ballast space S is formed by the upper plate and the ballast space S formed by the upper plate.

When a ballast control pipe 112 having an upper portion extending upward is installed to penetrate the upper plate 111c and the lower portion is exposed to the ballast space S and water is injected through the ballast control pipe 112, The balance adjustment for balancing the water in the ballast space S of the water tank 111 at the sea level becomes possible.

2C, the partition walls 114 are formed in a lattice shape intersecting with each other, so that the structural rigidity of the hypothetical buoyant body 111 is ensured and the water injected through the through holes 115 can flow, And the position of the ballast control pipe 112 can be freely selected.

2B and 2C, it can be seen that the ballast control pipe 112 is installed at the right corner of the temporary buoyant body 111. Also, by the ballast control pipe 112 provided at the corner, The injected water can be gradually filled in the whole of the temporary buoyant body 111 through the through hole 115 of the partition wall 114 and is advantageous for balance adjustment.

On the upper surface of the hypothetical buoyant body 111, as shown in FIG. 2A and FIG. 2C, an on-site concrete connection member 113 is integrally formed. It can be seen that such a spotted concrete connector 113 is formed in the form of a beam having a T-shaped cross section according to FIG. 2C.

That is, since the hypothetical buoyant body 111 is a kind of plastic material (polyethylene), when the temporary buoyant body 111 is made of the same material, .

It can be seen that the on-the-spot concrete connection member 113 extends in one direction on the upper surface of the hypothetical buoyant member 111. In this on-site concrete connection member 113, an insertion hole 116 is formed as shown in FIG. 2C So that it is possible to install the concrete reinforcing member 120 such as a reinforcing bar through the through-hole.

Therefore, the site-cast concrete connection member 113 functions to integrate the concrete paved for forming the site foundation foundation plate 200 with the assembly building fly's eye member 100.

As shown in FIGS. 2A and 2B, the segmented and buoyant buoyant members 110 are connected to each other to form a built-up and stacked buoyancy member 100. On the upper surface of the segmented buoyancy member 110, And a concrete reinforcing member 120 such as a reinforcing bar is installed in the on-the-spot concrete connecting member 113.

2A and FIG. 3A, the spot-placing base plate 200 is formed by curing a concrete placed inside a mold 210 installed along the outer surface of the assembling and building buoyancy body 100, And a concrete reinforcing member 120 such as a reinforcing bar, so that the rigidity can be ensured. The mold 210 is finally deformed as shown in FIG. 3B.

2A, the EPS block 130 is further installed on the upper surface of the assembled and suspended buoyant body 100, and the EPS block 130 is fixed to the mold by a concrete stiffener 120 such as a reinforcing bar. It is preferable to pour concrete therein to minimize the weight.

As a result, the buoyant body A for the floating structure according to the present invention has a small weight and is easy to assemble and install, and the EPS block 130 is mounted on the upper surface of the assembly building buoyancy body 100, As shown in FIG. 4, it is possible to secure the structural rigidity enabling the construction of the large floating structure (B) on the upper surface of the floating body (A) for the floating structure, It is possible to adjust the balance according to the construction of the large floating structure (B) by using the ballast function of the hypothetical buoyant body (100).

[Flowchart for producing the buoyancy body (A) for the floating structure for the sea]

FIGS. 3A and 3B illustrate a flow chart for manufacturing the buoyant body A for a floating structure according to the present invention.

3A, the segmented and buoyant buoyant body 110 constituting the buoyant body A for the floating structure is set on the sea (steel, sea, etc.) and a plurality of segmented buoyant bodies 110 The assembling and building buoyant body 100 is firstly assembled in the sea.

The number of connection of the segmented buoyant body 110 may be determined by considering a work space in which the floating structure can be installed, Since the self weight is not large, the connecting portions are not defective in the connection.

At this time, it can be seen that the ballast control pipe 112 of the segmented buoyant buoyant body 110 is arranged to extend upward and is arranged to be gathered at the central portion.

It can be seen that on the upper surface of the assembling and building buoyant body 100, the above-mentioned on-cast concrete connection member 113 is protruded and the on-site concrete connection member 113 and the concrete reinforcement member 120 are constrained to each other .

Next, a die 210 in the form of a vertical plate is disposed outside the assembly building buoyancy member 100. In addition, a large number of EPS blocks 130 are disposed above the spot-inserted concrete connecting members 113.

Further, it can be seen that a concrete reinforcing member 120 such as a reinforcing bar is additionally installed to prevent buoyancy generated when the EPS block 130 is buried in concrete. At this time, it can be seen that the ballast control pipe 112 is further extended upward from the upper surface of the mold 210.

The EPS block 130 and the concrete stiffeners 120 are embedded in the upper part of the cast concrete connection member 113 by pouring concrete into the mold 210. After curing, the mold 210 is demolded, The ballast control pipe 112 from the upper surface of the field-place foundation board 200 can be seen to be located at the center of the formwork It can be seen that it is further extended upward from the upper surface of the substrate 210.

At this time, the site-cast foundation board 200 integrated with the assembling and building buoyancy body 100 can be formed by dividing concrete in consideration of the size of the floating structure B and the like.

That is, as shown in FIG. 3B, the dies 210 in the form of a vertical plate are further disposed on the outer periphery of the field-placing foundation board 200 integrated with the assembly and building buoyancy body 100. Further, a large number of EPS blocks 130 are additionally disposed on the spotted concrete connection member 113.

Further, it can be seen that a concrete reinforcing member 120 such as a reinforcing bar is additionally installed to prevent buoyancy generated when the EPS block 130 is buried in concrete. At this time, it is also understood that the ballast control pipe 112 is further extended upward from the upper surface of the mold 210.

The EPS block 130 and the concrete stiffeners 120 are then embedded in the upper part of the concrete placement block 113. The concrete block 210 is then finally demolded It can be seen that the field mounted base plate 200 integrally formed with the assembling and building buoyant body 100 can be finally completed by the spotted concrete connection member 113 and the ballast control pipe 200 112 are further extended upward from the upper surface of the mold 210. [

It is a matter of course that it is possible to form the field-place foundation plate 200 by dividing the stage into a single stage or a multi-stage according to the desired thickness of the final spotting foundation board 200.

When water is injected into the ballast control pipe 112, the ballast space S of the assembling and building buoyancy body 100 is filled and the balance can be adjusted while adjusting the buoyancy.

[Balance adjustment by buoyant body for floating structure in the sea]

Fig. 4 shows the balancing action of the buoyant body A for a floating structure according to the present invention.

2A, the assembled temporary buoyant body 100 is located at the lower part of the buoyant body A for the floating structure. A plurality of the segmented buoyant buoyant bodies 110 are assembled together .

The ballast control pipe 112 is installed in each of the segmented buoyant bodies 110 so that buoyancy of each segmented buoyant body 110 can be adjusted by injecting water using a pump or the like not shown.

It can be seen that on the upper surface of the assembling and building buoyancy body 100, the field-placing foundation board 200 is formed integrally with the site-cast concrete connection member 113.

Also, as shown in FIG. 2A, the concrete stiffener 120 can secure the structural rigidity according to the construction of the large floating structure (B).

Thus, it can be seen that the floating structure (B) is installed on the top surface of the spot-placed foundation board (200).

Since the construction of the floating structure (B) is sequentially performed as in the first and second layers, a uniform load action is not applied to the assembling and building buoyancy body (100) integrated with the site foundation foundation board (200) And there is a case where additional construction is difficult due to the lack of balance.

In the present invention, water is injected into the ballast control pipe (112) by using water or the like around the water (W) to the segment building buoyant body (110) It can be seen that the balance adjustment becomes possible.

That is, the balance is adjusted by adjusting the buoyancy by filling the ballast space S of the segmented buoyancy member 110 divided by the partition with the ballast control pipe 112.

[Another embodiment of the buoyant body (A) for a floating structure for a floating body]

Figures 5A, 5B and 5C show another embodiment of the buoyant body (A) for a floating structure of the present invention.

First, when a large floating structure with a large size of the floating structure (B) is needed, the floating structure (A) for the floating structure as shown in FIG. 5A must be thick or large. It is relatively easy to adjust the size of the assembling and building buoyancy body 100. However, when the field-placing foundation board 200 is made larger, the thickness thereof becomes larger, There is a problem in that the number of times of pouring is increased to make it difficult to make the pouring quickly, and that the weight of the pouring is excessively large.

The present invention particularly optimizes the size of the buoyant body (A) for the floating structure by arranging the reinforcing beam (220) further in the field mounted base plate (200) .

That is, as shown in FIG. 5B, it is known that the steel beam 220a or the precast beam 220b or the like is further installed before the concrete is inserted when the field-cast foundation board 200 is manufactured to form the field foundation foundation board 200 And the installation direction of the reinforcing beams 220 may be longitudinal and transverse directions so as to cross each other so as not to interfere with the EPS block 130.

3A, the reinforcing beam 220 may be installed on the upper surface of the spot-inserted concrete joint member 113 together with the EPS block 130, and the concrete may be installed in the concrete after the concrete reinforcement member 120 is installed.

As shown in FIG. 5C, it can be seen that the buoyant body A for the floating structure with the additional reinforcement beam 220 is installed, and the floating structure B is installed on the buoyant body A for the floating structure. have.
