Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a storage tank,

The present invention relates to a method of manufacturing a storage tank and a method of manufacturing a storage tank.

Liquefied natural gas and liquefied petroleum gas mined from the sea are in a gaseous state at room temperature and normal pressure, so they are bulky and poor in transportability. Therefore, the gas mined at sea is often transported after it has been stored in liquefied form, that is, as liquefied gas.

In order to transport such liquefied gas, a liquefied gas storage tank is required to store and store the liquefied gas at a cryogenic temperature so that the liquefied gas can maintain the liquid state. The liquefied gas storage tank is provided with a heat insulating material for preventing heat exchange between the inside and the outside of the storage tank in which the liquefied gas is stored. Therefore, in order to manufacture a liquefied gas storage tank, it is necessary to install a heat insulating material.

On the other hand, in order to install the heat insulating material in the liquefied gas storage tank, a foot plate for installing the heat insulating material is provided around the storage tank. That is, the scaffold provides a path through which the heat insulating material constituting the storage tank moves, and a person performs the heat insulating material installation work on the scaffold.

In addition, the heat insulating material installation work of the liquefied gas storage tank is generally performed in a state in which a floating body having a storage tank is floated in water. Therefore, it is necessary to consider the tilting of the working space due to the rolling motion when the work is carried out while the floating body floats on the water.

Such a rolling phenomenon is also a problem in the installation work of the insulation. 1, a pedestal 1 and a post 2 for supporting the pedestal 1 may be provided around the storage tank.

However, when a rolling sway phenomenon occurs during the heat insulating material installation work, the load of the foot plate 1 is shifted to one side. As a result, the foot plate 1 tilts with respect to the storage tank. A side stopper 3 for preventing the inclination of the foot plate by connecting and supporting the side wall 5 and the post 2 of the storage tank is provided to prevent the inclination of the foot plate 1 . A side plate 4 for effectively supporting the side wall of the storage tank 5 may be provided at one end of the side stopper 3 on the side wall 5 side.

However, since the side stopper 3 and the side plate 4 must be separately manufactured, there arises a problem that material and installation cost increase. In addition, by providing the side stoppers 3 and the side plates 4, there arises a problem that a restriction is imposed on utilizing a part of the inside of the storage tank or the surrounding space.

Accordingly, it is an object of the present invention to prevent a tilting of a foot plate to a storage tank without a separate constitution in the manufacturing process of the liquefied gas storage tank.

According to an aspect of the present invention, there is provided a footrest used in a manufacturing process of a storage tank for storing liquefied gas, the footrest comprising: a footrest frame constituting a skeleton of the footrest; And a side plate for a foot plate provided at one end of the foot frame and capable of contacting one side wall of the storage tank; Wherein the footrest is provided so as to be spaced apart from the bottom of the storage tank.

The vertical cross-sectional area of the foot plate may be greater than the vertical cross-sectional area of the foot frame.

The scaffold may be of a telescopic type so that the scaffold side plate may contact one side wall of the storage tank or be spaced from one side wall of the storage tank.

Wherein the foot frame includes a fixed foot frame fixed to the storage tank; And a movable pedestal frame movable relative to the storage tank so as to be able to contact one side wall of the storage tank or to be spaced from one side wall of the storage tank; The side plate for footrest may be provided at one end of the movable footrest frame.

According to another aspect of the present invention, there is provided a method of installing a footrest for use in manufacturing a storage tank for storing a liquefied gas, the method comprising: Wherein one end of the foot frame constituting the skeleton of the foot plate is provided with a foot side plate capable of contacting with one side wall of the storage tank and the vertical side face of the foot side frame Is provided with a post which supports the foot so as to prevent the foot from tilting and a side stopper which connects one side wall of the storage tank with a vertical cross section of the foot frame There is provided a method of installing a scaffold for manufacturing a storage tank which is not required.

The scaffold may be of a telescopic type so that the scaffold side plate may contact one side wall of the storage tank or be spaced from one side wall of the storage tank.

Wherein the foot frame includes a fixed foot frame fixed to the storage tank; And a movable pedestal frame movable relative to the storage tank so as to be able to contact one side wall of the storage tank or to be spaced from one side wall of the storage tank; . ≪ / RTI >

A hole may be formed in the side surface of the fixed footrest.

The footrest can move through the hole and fix the moving footrest to the fixed footrest by connecting the movable footrest and the fixed footrest. As shown in FIG.

According to the present invention, the tilting of the foot plate to the storage tank can be prevented without a separate structure in the manufacturing process of the liquefied gas storage tank.

1 is a view showing an example of a structure of a footrest used in the process of manufacturing a liquefied gas storage tank and its surroundings.
2 is a view showing a foot frame and a peripheral structure of a foot plate according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. While the present invention will be described with reference to the embodiments shown in the drawings, it is to be understood that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims

On the other hand, the present invention can be applied to a manufacturing process of a liquefied gas storage tank for storing liquefied gas, which is provided in a floating body. For example, the present invention can be applied to a process of installing a heat insulating material in a storage tank during the manufacture of a liquefied gas storage tank. Further, the liquefied gas in this specification should be interpreted as a concept including liquefied natural gas and liquefied petroleum gas.

2 is a view showing a foot frame and a peripheral structure of a foot plate according to an embodiment of the present invention.

As shown in FIG. 2, according to one embodiment of the present invention, a foot plate used for manufacturing the liquefied gas storage tank is provided around the side wall 5 of the liquefied gas storage tank. The footplate provides a path through which the insulation moves during the installation process of the insulation material constituting the storage tank, and the person performs the installation of the insulation material on the footplate.

The scaffold may be installed so as to be spaced from the bottom of the storage tank. A post 20 may be provided between the bottom of the storage tank and the footplate to serve as a pillar for supporting the footplate so that the footplate can be spaced from the bottom of the storage tank.

Meanwhile, the foot plate according to one embodiment of the present invention may be telescopic type which is stretchable.

During the manufacture of the storage tank, the footplate may be in contact with the side wall of the storage tank, and sometimes away from the side wall of the storage tank. Accordingly, the foot plate according to one embodiment of the present invention may be telescopic type that can be stretched to be selectively adjustable in distance from the side wall of the storage tank according to circumstances.

In addition, the foot plate may be provided with a foot plate (12) serving as a skeleton and a foot plate (not shown) provided on the foot frame so that the foot plate can maintain its original shape in the manufacturing process of the storage tank. That is, the above-described heat insulating material mounting work can be performed by the foot plate provided with the foot plate on the foot frame 12.

As described above, the scaffold may be of a telescopic type that is stretchable, for which the scaffold frame 12 may include a fixed scaffold frame 14 and a movable scaffold frame 16. The meaning of 'fixed type' and 'movable type' means that the foot frame can be moved relative to the side wall 5 of the storage tank in the manufacturing process of the storage tank (that is, the process of installing the insulation) after the installation of the footplate is completed Is defined. That is, the 'fixed footing frame' means a footing frame that does not move relative to the side wall 5 of the storage tank, and the 'mobile footing frame' means a footrest frame capable of moving relative to the side wall 5 of the storage tank Means a foot frame.

At this time, the movable footrest frame 16 is provided closer to the side wall 5 than the fixed footrest frame 18. 2 shows a case where the movable pedestal frame 16 is provided on the left side closer to the side wall 5 than the fixed pedestal frame 14 when the side wall 5 is formed on the left side.

As described above, since the movable footrest frame 16 can move relative to the side wall 5, it can move relative to the fixed footrest frame 14 as well. To this end, part or all of the movable footrest frame 16 as shown in Fig. 2 may be a structure that can be inserted into the fixed footrest frame 14. That is, in the manufacturing process of the storage tank, the movable pedestal frame 16 may be inserted into the fixed pedestal frame 14 or moved in the horizontal direction so as to protrude from the fixed pedestal frame 14, if necessary. For this purpose, the interior of the fixed footing frame 14 may be hollow. In addition, the movable pedestal frame 16 may be moved in the horizontal direction, and the fixed pedestal frame 14 may be inserted into the movable pedestal frame 16 as shown in FIG. In this case, the movable pedestal frame 16 may be hollow.

On the other hand, in many cases, the manufacturing process of the storage tank is performed while the floating suspension having the storage tank floats on the sea. Therefore, it is necessary to consider the tilting of the working space due to the rolling motion when the work is carried out while the floating body floats on the water. If a rolling phenomenon occurs during the insulation installation work, the load on the foot plate is shifted to one side. As a result, the foot plate tilts relative to the storage tank. According to an embodiment of the present invention, a side stopper and a side plate may be separately provided as described above in order to prevent the tilting phenomenon of the foot plate. However, And a side plate for a foot plate 30 is provided at one end of the storage tank side wall 5 side.

The side plate for footboard 30 is a structure for effectively fixing the footplate to the side wall 5 instead of providing the side stopper and the side plate. Therefore, according to the present invention, it is possible to prevent the tilting of the foot plate due to the rolling motion in the manufacturing process of the storage tank without any additional configuration.

As shown in Fig. 2, the vertical cross-sectional area of the side plate for footboard 30 may be larger than the vertical cross-sectional area of the footplates 14, 16. This is to more effectively support the footrest, thereby effectively preventing inclination of the footrest.

Meanwhile, as described above, the movable pedestal frame 16 is movable, and it is necessary to fix the movable pedestal frame 16 at a position where the movement is completed after the movement of the movable pedestal frame 16 is completed according to the manufacturing process of the storage tank. If the movable pedestal frame 16 is not fixed to the point but can move horizontally after the movement of the movable pedestal frame 16 is completed, there is a possibility that the risk of accidents in the manufacturing process of the storage tank becomes large.

Therefore, according to one embodiment of the present invention, a configuration may be provided in which the movable pedestal frame 16 and the fixed pedestal frame 14 are fixed to each other after the movement of the movable pedestal frame 16 is completed.

To this end, a hole 40 may be formed on the side surface of the fixed footing frame 14. Further, a fixing unit 50 that can move through the holes 40 may be provided. The fixed unit 50 can move in the vertical direction with respect to the fixed pedestal frame 14 through the hole 40. The fixed unit 50 may be a screw. A method of fixing the fixed pedestal frame 14 and the movable pedestal frame 16 using the fixed unit and the hole will be described as follows.

When the movement of the movable pedestal frame 16 is required, the fixed unit 50 is spaced apart from the movable pedestal frame 16. This is for allowing the movable footrest frame 16 to move in the horizontal direction. Thereafter, the movable footrest frame 16 is moved in the horizontal direction to a desired position. When the movement of the movable pedestal frame 16 is completed, the fixed unit 50 moves and comes into contact with the movable pedestal frame 16 to connect and fix the fixed pedestal frame 14 and the movable pedestal frame 16 . When the fixing unit 50 is a screw, the fixed pedestal frame 14 and the movable pedestal frame 16 are connected and fixed by screwing and loosening the screws. For example, when the screw is loosened, the connection between the fixed pedestal frame 14 and the movable pedestal frame 16 is released so that the fixed pedestal frame 14 is movable. When the screw is tightened, the fixed pedestal frame 14 A movable footrest frame 16 is connected to fix the movable footrest frame 16.

2, the movable pedestal frame 16 can be inserted into the fixed pedestal frame 14, and the inside of the fixed pedestal frame 14 is fixed to the inside of the fixed pedestal frame 14 It can be applied in the case of an empty structure. 2, the fixed pedestal frame 14 can be inserted into the movable pedestal frame 16, so that the movable pedestal frame 16 can be applied in the opposite manner to that described above have. That is, a hole can be formed in the movable scaffold frame, and the fixed unit passing through the hole is contacted with or spaced from the fixed scaffold frame 14, so that the movable scaffold frame can be moved and fixed.
