Description

Technical Field [0001] The present invention relates to a fixing support for a liquefied gas insulating structure,

The present invention relates to a fixed support for a liquefied gas insulation structure and a method of manufacturing a liquefied gas insulation structure using the same. More particularly, the present invention relates to a fixed support for a liquefied gas insulation structure, And a method of manufacturing a liquefied gas insulating structure using the same.

The liquefied gas is a liquid made by cooling or compressing gas, and is a gas phase liquid phase change industrially at room temperature for convenience of transportation and storage. One of the most widely used and important resources in liquefied gas is Liquefied Natural Gas (LNG). Liquefied natural gas refers to a colorless transparent cryogenic liquid with methane-based natural gas cooled to -162 degrees Celsius and its volume reduced to 1/600.

As such liquefied gas is used as an important energy source, an efficient transportation method capable of transporting liquefied gas from a production base to various demand sites has been examined. As part of this effort, a liquefied gas transport vessel capable of transporting large volumes of liquefied gas through the sea has been developed.

The liquefied gas transport vessel shall be provided with a liquefied gas cargo hold capable of storing and storing the liquefied gas liquefied at a cryogenic temperature. Since the liquefied gas has a higher vapor pressure than the atmospheric pressure and has a boiling temperature of ultra-low temperature, in order to safely store and store such liquefied gas, the liquefied gas storage window must be made of a material that can withstand the extremely low temperature, It should be designed with a unique insulation panel structure to prevent intrusion.

Generally, the heat insulating structure of the liquefied gas holding window is composed of a structure in which a primary barrier, an upper insulating board, a secondary barrier and a lower insulating board are sequentially combined. This is to prevent additional leakage of the fluid in the secondary barrier, even if there is a small leakage of cryogenic fluid in the primary barrier. The secondary barrier includes a secondary kitchen wall and a secondary auxiliary barrier.

Since the size of the liquefied gas hold is very large, tens of thousands of insulation structures of the liquefied gas hold are installed in a unit box. The heat insulating structure of the liquefied gas hold is formed by fixing a plurality of lower heat insulating boards having the same thickness on the inner wall of the hold, installing a secondary main wall on the lower heat insulating board, forming an upper heat insulating board and a primary barrier .

Meanwhile, an upper auxiliary panel made of a material such as a flywood is inserted between the upper insulating board and the primary wall to compensate the rigidity of the upper insulating board. The upper auxiliary panel is provided with an anchor strip, And a plurality of primary walls adjacent to each other are welded to each other to secure hermeticity and are installed on the upper heat insulating board.

Liquefied gas holders are very large in size, so tens of thousands of primary barriers are required for welding on anchor strips. When the welding work is manually performed by a worker, labor and working time are excessively consumed, which is inefficient. Therefore, it is necessary to automatically perform a welding process using an automatic welding device or the like. However, in the welding process, it is required to support a device such as a welding device or a guide rail for guiding the traveling direction of the welding device.

Therefore, there is a need for a method for stably supporting a device or member used for a manufacturing process of a heat insulating structure or a welding process without affecting the performance and quality of the heat insulating structure of the liquefied gas holding window.

In addition, the liquefied gas cargo holds include not only the facilities installed on the sea, but also those used for facilities to store or produce liquefied gas installed on land.

Hereinafter, a membrane-type cargo hold of a liquefied gas holding cargo will be described as an example. FIG. 1 is a perspective view showing an example of a heat insulating structure of a liquefied gas holding window to which a fixed support of a liquefied gas insulating structure and a method of manufacturing a liquefied gas insulating structure using the same according to an embodiment of the present invention is applied. FIG. 1 is a block diagram illustrating an exemplary embodiment of the present invention. Referring to FIG.

1, the liquefied gas holding window surrounds a space capable of accommodating liquefied gas and includes a primary barrier 50 in direct contact with the liquefied gas, a primary barrier 50 surrounding the primary barrier 50, And an outer wall surrounding and supporting the liquefied gas insulating structure.

The heat insulating structure can be made of a double heat insulating structure in order to improve the heat insulating performance and to facilitate repair and maintenance. Specifically, the heat insulating structure of the liquefied gas holding window may include a lower heat insulating board 20 provided on the outer wall side and an upper heat insulating board 30 provided on the upper side of the lower heat insulating board 20. [ An inner hull can be used as the outer wall and supports the load of the storage fluid.

The lower insulation board 20 may be coupled to the outer wall by various fixing members including a stud bolt or the like so that the lower insulation panel 20 can be firmly fixed to the outer wall. The lower reinforcement panel 21 may be made of a material such as plywood or the like and attached to the bottom surface of the lower heat insulation board 20 using an adhesive such as epoxy glue or the like.

On the upper portion of the lower insulation board 20, a lower sub-panel 22 may be laminated for installing a secondary barrier 40 to be described later. The lower sub-panel 22 may be made of a material such as plywood or the like as the lower reinforcement panel 21 and may be attached to the lower heat-insulating board 20 using an adhesive such as epoxy glue.

A panel fixing unit 25 for fixing the upper heat insulating board 30 may be provided on the upper side of the lower heat insulating board 20. The panel fixing unit 25 may be coupled to the upper surface of the lower sub-panel 22 and the panel fixing unit 25 may have a coupling portion 25a And a protrusion 25b protruding upward from the lower sub-panel 22 and engaging with the upper heat-insulating board 30. [ The protrusions 25b may be threaded on the outer circumferential surface and coupled with the upper heat-insulating board 30 in a screwed manner. The panel fixing unit 25 is welded to the secondary barrier 40 to be described later.

The insulating structure of the liquefied gas hold can include a secondary barrier (40) interposed between the upper and lower insulating boards (30, 20). The secondary barrier 40 protects the lower insulation board 20 even if the primary barrier 50 loses airtightness, thereby greatly reducing the time and cost required for repair and maintenance.

The secondary barrier 40 may be made of a metallic material such as an INVAR, stainless steel (SUS), or an aluminum alloy in the same manner as the primary barrier 50, and may be formed of a rigid triplex and a shuffle triplex (Supple triplex) can be used.

The secondary barrier 40 may be attached to the lower insulation board 20 by welding. When the secondary barrier 40 is attached by welding, it is welded to an anchor strip 24 made of a metal material and joined to the lower sub-panel 22. The anchor strip 24 may be mechanically coupled to the lower sub-panel 22 by means of a rivet or the like and the anchor strip 24 may be received in a groove formed in the lower sub- As shown in Fig.

The anchor strip 24 is positioned below the weld line during welding between adjacent sheets of the secondary barrier 40 as described later, so that the secondary barrier 40 sheet can be prevented from being deformed by welding heat. The anchor strips 24 may be arranged in different directions to form an intersection. For example, two strips orthogonal to each other.

In Fig. 1, eight lower insulation boards 20 are disposed adjacent to each other, and a secondary barrier 40 having a shape corresponding to the shape of the anchor strip 24 provided on the lower sub-panel 22 is formed in eight lower insulation But it is not limited to the number and the shape of the board 20.

The secondary barrier 40 can be constituted by a plurality of secondary barrier 40 sheets and the secondary barrier 40 has a hole through which the panel fixing unit 25 can pass. After the installation of the secondary barrier 40 is completed, the secondary barrier 40 and the panel fixing unit 25 are welded to each other to ensure airtightness and continuity of the heat insulating structure.

After one secondary barrier 40 sheet is fixed, another secondary barrier 40 sheet is fixedly installed on one adjacent side. At this time, the sheets of the secondary barrier 40 and the sheets of the secondary barrier 40 adjacent to each other are disposed so as to overlap with each other on the adjacent edges.

The secondary barrier 40 may include a corrugation 41 to have a low surface stiffness. The corrugated portion 41 can elastically deform its shape corresponding to the thermal stress applied to the secondary barrier 40, thereby reducing the thermal stress at the welded portion.

The secondary barrier 40 includes a first corrugation 41-1 and a second corrugation 41-2 which are arranged in different directions and an intersection 42 where the two corrugations intersect. The thermal stress acting in the in-plane direction of the secondary barrier 40 can be relieved by the wrinkles 41 in different directions. That is, the thermal stress acting in the longitudinal direction of the first wrinkled portion 41-1 is canceled by the elasticity of the second wrinkled portion 41-2, and the thermal stress acting in the longitudinal direction of the second wrinkled portion 41-2 The thermal stress can be solved by the stretchability of the first wrinkle portion 41-1.

In FIG. 1, the two wrinkles 41 are arranged in directions orthogonal to each other. However, the wrinkles 41 may be formed in various numbers according to design requirements. For example, when the folds are arranged in three directions, they may be provided at an angle of 60 degrees with respect to each other.

The corrugated portion 41 provided in the secondary barrier 40 may be formed in a convex shape downward and may be located at the boundary of the adjacent lower heat-insulating board 20. Chamfer is formed at the corner of the lower heat insulating board 20 to prevent interference with the corrugated portion 41.

An upper reinforcing panel 31 may be coupled to the bottom surface of the upper insulating board 30 so that the upper insulating board 30 can be firmly fixed to the lower insulating board 20. The upper reinforcing panel 31 may be made of a material such as plywood or the like and may be attached to the upper heat insulating board 30 using an adhesive such as epoxy glue.

The upper insulating board 30 and the upper reinforcing panel 31 are provided with through holes 30a and 31a so that protrusions of the panel fixing unit 25 can be inserted or inserted. A thread is formed on the inner circumferential surface of the through holes 30a and 31a so that the upper heat insulating board 30 can be fixedly installed by screwing the projecting portion 25b of the panel fixing unit 25. [ The airtightness can be maintained by inserting the foam plug 30b into the through holes 30a and 31a.

The upper insulating board 30 may be provided in a size and shape corresponding to the area where the two lower insulating boards 20 are disposed adjacent to each other and may be fixed by the two panel fixing units 25, Can be prevented from rotating.

An upper sub-panel 32 may be provided on the upper surface of the upper insulation board 30 for installing the primary barrier 50. The upper sub-panel 32 may be made of a material such as plywood or the like and may be attached to the upper heat-insulating board 30 using an adhesive such as epoxy glue or the like.

An anchor strip (34) may be provided on the upper surface of the upper sub-panel (32). The anchor strip 34 may be made of a metal such as SUS and welded to the primary barrier 50 and may be mechanically coupled to the upper sub-panel 32 by rivets or the like. A groove 32a may be formed on the upper surface of the upper sub-panel 32 so that the anchor strip 34 may be seated and the anchor strip 34 may not protrude from the upper surface of the upper sub-

The anchor strips 34 may be arranged in different directions to form an intersection. For example, two strips orthogonal to each other and may be provided at a position corresponding to a corner shape of the primary barrier 50. The anchor strip 34 is provided with a fixed support 100 to be described later.

The primary barrier 50 is welded to the anchor strip 34 of the upper sub-panel 32. The primary barrier 50 may be made of a metal material such as INVAR, stainless steel (SUS), or aluminum alloy so as to maintain its physical and chemical state even at a low temperature. The primary barrier 50 may be formed by connecting a plurality of unit primary barrier 50 sheets, and they are bonded and bonded to each other to secure airtightness.

Because the primary barrier 50 is in direct contact with the cryogenic storage fluid, it is exposed to rapid contraction and expansion. The primary barrier 50 may accumulate fatigue due to repeated heat shrinkage and thermal expansion, or may damage the welded portion during heat shrinkage and degrade the airtightness. Due to this problem, the primary barrier 50 includes the corrugations 51 to have an in-plane stiffness. The corrugated portion 51 can elastically deform its shape corresponding to the thermal stress applied to the primary barrier 50, thereby reducing the thermal stress at the welded portion.

The primary barrier 50 includes first and second corrugated portions 51-1 and 51-2 disposed at different directions and an intersection portion 52 where the two corrugations intersect with each other. The thermal stress acting in the in-plane direction of the primary barrier 50 can be relieved by the wrinkles 51 in different directions. That is, the thermal stress acting in the longitudinal direction of the first wrinkled portion 51-1 is canceled by the elasticity of the second wrinkled portion 51-2, and the thermal stress acting in the longitudinal direction of the second wrinkled portion 51-2 Can be solved by the stretchability of the first wrinkled portion 51-1.

Generally, the liquefied gas holders are very large in size and the number of primary barriers 50 to be welded is also very large. Accordingly, the primary barrier 50 is welded using an automatic welding device. In order to operate the automatic welding device, an automatic welding device or a guide rail is fixedly installed on the heat insulating structure, and the automatic welding operation is performed.

However, when a separate structure is provided in the heat insulating structure for fixing the member or device 200 used in the manufacturing process of the heat insulating structure such as the automatic welding device or the guide rail, the performance of the heat insulating structure may be affected, Labor and time are required.
