In general, liquefied natural gas refers to a cryogenic liquid which is reduced by compressing its volume to 1/600 by cooling a natural gas mainly composed of methane to minus 162 degrees. As liquefied natural gas emerges as an energy resource, an efficient transportation method that can transport a large amount from the production base to the receiving site is considered to use this gas as energy, and the result is liquefaction for sea transportation of liquefied natural gas. It appeared as a natural gas (Liquefied Natural Gas) LNG carrier.

LNG carriers need to design and build tanks that can withstand ultra-low temperatures of minus 162 degrees and require the highest level of drying technology for the entire shipbuilding industry, and classify LNG carriers according to the most characteristic type of tank. It can be divided into independent type and membrane type.

The liquefied natural gas storage tank of such a liquefied natural gas carrier has a heat dissipation panel made of two layers of urethane foam attached to the inner wall and welded a membrane inside the heat dissipation panel. The adhesive is applied to each other to attach them.

The storage tank of the liquefied natural gas transport ship is formed of a very thin membrane, and the height thereof is considerable, so that the scaffolding system does not fall or come into contact with the storage tank during installation work of the storage tank and surrounding facilities. You should work by configuring it. This general scaffolding system is as shown in Figure 1 below.

1 is a perspective view showing a general scaffolding system.

Referring to Figure 1, the storage tank (1) stores the liquefied natural gas, the scaffolding pillars (2) are installed at each of the left and right sides at both ends, the support panel (5) is the working and moving space of the operator, The board bearer 4 supports the support panel, and the guide rail 3 guides the space when the worker moves or works and supports the worker.

In one side space in which the storage tank 1 is installed, the scaffolding pillars 2 are installed on the left and right sides of both ends, respectively, and the support bearings are connected to predetermined heights of the scaffolding pillars 2, respectively. And the support panel 5 is seated on the upper side of the board bearing 4, the support panel 5 is fixed to the board bearing (4). In addition, the guide rail (3) is fixed to the footrest column (2) on one side and the other side at a height that can guide or support the operator to the upper side of the support panel (5).

Here, the guide rail 3 is fastened and fixed to a hinge 2a (see FIG. 2) formed by welding on the outer circumferential surface of the scaffolding pillar 2, which is an enlarged portion A of FIG. 1. As shown in.

2 is an enlarged perspective view of a portion A of FIG. 1 showing a conventional guide rail connecting device.

Referring to Figure 2, the conventional guide rail (3) connecting device is bent to cover the front and left and right sides except for the upper part and the lower part and the part that is welded to the outer peripheral surface of the scaffolding pillar (2) It includes a hinge (2a) is formed in the penetrating portion (2b) on the inside, and fastening portions formed on both ends of the guide rail (3), respectively. Wherein the fastening portion is formed through the upper plate (3a) forming a plane on the upper side and the lower surface plate (3b) forming a plane on the lower side and the insertion hole (3c) formed in the plane of the upper plate (3a) and the lower plate (3b) ), And a taper key 3d (Taper Key) through which the upper plate 3a and the lower plate 3b are inserted into the insertion hole 3c. Here, the upper plate 3a and the lower plate 3b are spaced apart from each other at one side and bent at the other side to be connected to each other so that the front surface of the fastening part is opened to form a predetermined space at the center.

In the above configuration, the fastening part is fastened so that the hinge 2a is positioned inward through an open space at the front, and the upper plate 3a is disposed on the upper side of the hinge 2a. 3b is in close contact with the lower end of the hinge 2a, and the insertion hole 3c of the upper plate 3a and the lower plate 3b coincides with the penetrating portion 2b of the hinge 2a. .
