Description

Technology Field

[0001] The present invention relates to an aluminum deck, and more specifically, to a lightweight and safe aluminum deck installed in a workspace such as a membrane of an LNG vessel for workers to move and work. Background Technology

[0003] Recently, as environmental issues such as global warming have emerged worldwide, the government's eco-friendly policies for carbon reduction and the public's interest in eco-friendliness are on the rise.

[0004] In particular, there is a trend of applying strict regulations to means of transportation that emit carbon dioxide using fossil fuels, such as automobiles and ships powered by gasoline or diesel fuel.

[0005] In accordance with these eco-friendly policies, the development and adoption of eco-friendly energy vehicles, such as hydrogen cars and electric cars, are accelerating in the automotive sector, and the development of hydrogen ships, ammonia ships, and LNG ships is also accelerating in the shipbuilding sector.

[0006] In particular, there is very high interest in LNG vessels in the shipbuilding sector, and a large volume of orders have actually been received, leading to the construction of LNG vessels.

[0007] As interest in these LNG vessels increases and they are being mass-produced, interest in LNG carriers to supply the aforementioned LNG is also rising.

[0008] The above LNG carrier is a vessel specialized in transporting liquefied natural gas, which is produced by reducing the volume of natural gas to about 1 / 600 at a temperature of minus 162 degrees. Since it must withstand high pressure and extremely low temperatures, it is essential to manufacture insulated tanks capable of withstanding these conditions.

[0009] These LNG carriers can be broadly classified into Moss type and membrane type.

[0010] The Moss type has the advantage of ensuring sufficient stability because the structure of the cargo tank is a relatively simple spherical shape, and the low impact phenomenon allows space for inspection and maintenance to be secured within the hull.

[0011] However, there are disadvantages, such as reduced space efficiency of the hull and the requirement of advanced technology for manufacturing spherical steel plates.

[0012] To solve these problems, rectangular prism-shaped membranes have recently been mainly used.

[0013] It is manufactured by attaching thin steel plates as protective barriers, which allows for the free deformation of the thin steel plates, enabling efficient use of space, increased payload, and minimized protrusion on the deck, thereby offering the advantage of high stability.

[0014] In order to manufacture these membrane-type LNG tanks, scaffolding is installed so that workers can work at a height on the membrane, and a platform made of wooden plywood is placed on top of it to be used as a workspace.

[0015] However, the aforementioned plywood for timber has a problem in that, due to the environment where work is mainly carried out near the sea, it absorbs moisture generated in the sea, which increases its weight and weakens its durability.

[0016] In addition, in winter, there was a problem where the internal moisture would freeze after absorbing moisture, causing slippage on the flat wooden platform and potentially posing a safety risk to workers.

[0017] In addition, there was a problem where the worker's workspace was reduced because it was difficult to dismantle the scaffolding even when the worker was not moving.

[0018] In addition, there is a demand for work decks that enhance durability and stability and are easy to assemble and disassemble, in addition to the membrane work area of ​​LNG vessels, in various other workspaces.

[0019] Therefore, in recent years, in order to solve these problems, decks that are safe, resistant to the external environment, and easy to install and dismantle have been used.

[0020] For example, Korean Registered Patent Publication No. 10-2344623 (December 24, 2021) discloses an aluminum deck panel that is easy to install, reduces the overall load, allows for easy replacement to diversify colors, and reduces fatigue by being formed to act as a cushion when moving over a deck board.

[0021] However, even in this case, the top cover portion (200) and the main body (300) of the deck panel are each configured, so when installing, the top cover portion (200) and the main body must be connected to each deck panel, and the connected deck panels must be joined together to complete the installation, so there is still a limitation that installation and dismantling are difficult.

[0022] To solve these problems, if an aluminum deck consisting only of a frame and a deck is provided that is easy to assemble and disassemble, the deck can be quickly installed and disassembled in the large space of the membrane, thereby reducing the waste of manpower and time required for deck installation and disassembly.

[0023] In addition, since installation and dismantling can be carried out quickly, unused parts can be disassembled and stored, making it easy to secure workspace for workers.

[0024] In addition, the inventor arrived at the present invention by noting the possibility that using an aluminum deck instead of conventional wood would make it resistant to external environments such as moisture, thereby eliminating the need for frequent replacement and increasing durability, which could reduce economic losses.

[0047] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings in order to enable a person skilled in the art to easily practice the present invention.

[0048] FIG. 1 is an overall perspective view of an aluminum deck according to one embodiment of the present invention.

[0049] FIG. 2 is an upper and lower view of an aluminum deck according to one embodiment of the present invention.

[0050] FIG. 3 is a configuration diagram of a folding device (600) according to one embodiment of the present invention.

[0051] FIG. 4 is an application diagram of an anti-slip part according to one embodiment of the present invention.

[0052] FIG. 5 is an example diagram of an aluminum deck connection according to one embodiment of the present invention.

[0053] Referring to FIGS. 1 to 5, the aluminum deck (1000) is installed in a workspace such as an LNG vessel membrane and is connected to the scaffolding pipe of the workspace. It is an aluminum deck that can be unfolded when a worker moves and folded when not in use to secure additional workspace for the worker.

[0054] As illustrated in FIGS. 1 and 2, the aluminum deck (1000) of the present invention may be composed, overall, of an outer frame (100), a deck frame (200), a joist frame (300), a deck section (400), and a fastening member (500).

[0055] First, the outer frame (100) may be formed by connecting a plurality of vertical frames (110) and horizontal frames (120) overall.

[0056] The lengths of the vertical frame (110) and the horizontal frame (120) may vary depending on the application site and situation, and may be formed as a rectangle or a regular hexagon.

[0057] The above outer frame (100) may have a through hole (130) formed by penetrating one side.

[0058] The above through hole (130) may be combined with the deck portion described above later.

[0059] Additionally, the outer frame (100) may additionally be provided with drainage holes (140), and the drainage holes (140) may be formed in multiple numbers by penetrating from the upper part to the lower part of the outer frame.

[0060] With the above drainage hole (140) provided, the problem of increased weight due to accumulated moisture after deck installation and corrosion caused by moisture can be prevented, thereby improving durability.

[0062] Next, the deck frame (200) may be formed by connecting vertically to the horizontal frame (120) and arranging multiple frames at regular intervals.

[0063] In addition, one side of the deck frame (200) may be provided with a plurality of fastening holes (210) formed through it at a predetermined distance apart.

[0064] It is most preferable that the above fastening hole (210) be drilled toward the top so that it can be joined to the deck section thereafter.

[0065] The above-mentioned joist frame (300) is vertically connected to the above-mentioned vertical frame and deck frame and may support the above-mentioned deck frame (200).

[0066] The joist frame may be joined vertically on the same plane as the vertical frame and deck frame, or it may be joined vertically in contact with the lower part of the vertical frame and deck frame to support the vertical frame and deck frame.

[0067] Additionally, the above-mentioned joist frame (300) may be provided in multiple numbers and combined with the deck frame (200) in a grid shape.

[0068] The supporting capacity of the deck frame (200) can be improved, and the durability of the deck frame (200) can be increased by preventing sagging that may occur in the central part of the deck frame over time after the deck is installed.

[0069] In addition, the rigidity of the deck frame (200) can be increased so that it can be supported more stably when a worker moves or moves work tools.

[0070] The above deck portion (400) has an overall flat panel shape and can be mounted so that the lower surface of the deck portion contacts the upper part of the outer frame (100) and the deck frame (300).

[0071] The above deck section (400) may be provided as a single unit of the same size as the outer frame (100) and connected, or a plurality of panels formed of small pieces may be arranged continuously and connected.

[0072] If the above deck section (400) is provided in a single unit, there will be no additional attachment process, making it easy to install and dismantle.

[0073] If the above deck section (400) is provided in multiple units, there will be an advantage of easy maintenance because when a defect such as damage to the deck section (400) occurs, only the defective deck section needs to be replaced.

[0075] Referring to FIG. 3, the deck portion (400) may include an anti-slip portion (410).

[0076] The above anti-slip portion (410) may be provided in the form of a protruding checkerboard shape or a hole perforated in the upward direction, and may be formed continuously or repeatedly at regular intervals on the upper surface of the deck portion (400).

[0077] When the above anti-slip part (410) is provided with a protruding checkerboard shape, the checkerboard shape generates friction when the deck surface and the work shoe come into contact when a worker moves, thereby preventing slipping and reducing the contact area, which can increase stability.

[0078] When the above anti-slip part (410) is provided in the form of a hole perforated in the upward direction, the outer surface of the hole generates friction when the work shoe contacts it, thereby preventing slipping, and the hole shape prevents the entire sole of the work shoe from coming into contact with the deck surface, thus increasing stability when the worker moves.

[0079] The fastening member (500) may be inserted through the through hole (130) of the deck portion (400) and the outer frame (100) or the fastening hole (210) of the deck frame (200), and may be able to combine and fix the deck portion (400) and the outer frame (100) or the deck frame (200).

[0080] The above fastening member (500) may be a rivet or a screw.

[0081] If rivet-type fasteners are used, the deck section can be installed and secured through a simple process.

[0082] If a screw-type fastening member is used, it will be effective in strongly securing the deck frame and the deck section because a nut is additionally provided for fixation.

[0083] FIG. 4 is a configuration diagram of a folding device (600) according to one embodiment of the present invention.

[0084] Referring to FIG. 4, the aluminum deck (1000) may additionally be equipped with a folding device (600).

[0085] The above folding device (600) may be composed of a rotating part (610), a rotating shaft (620), and a connecting part (630).

[0086] First, the above-mentioned pivoting part (610) may be formed at the end of the vertical frame (110) or horizontal frame (120) to enable the aluminum deck to be rotated by a predetermined angle.

[0087] It is preferable that the above rotation angle be set to 75 to 90 degrees, which will allow for the formation of a movement space and work space for workers while minimizing interference with the scaffolding pipes when the aluminum deck connected to the scaffolding pipes is rotated.

[0088] The above-mentioned pivot shaft (620) may be in the shape of a column, with one end connected to the pivot part and the other end extended.

[0089] The above-mentioned connecting part (630) may be provided in a 'C' shape with an opening in one direction overall, and may be formed by extending from the other end of the rotation axis.

[0090] Additionally, the binding portion (630) may be provided with a binding hole (631), which may be formed by penetrating both sides of the binding portion.

[0091] FIG. 5 is an example diagram of an aluminum deck connection according to one embodiment of the present invention.

[0092] Referring to FIG. 5, the opening of the connecting part (610) formed by extending from the outer frame (100) can be inserted into the scaffolding pipe to be installed.

[0093] Afterwards, the scaffolding pipe and the aluminum deck (1000) can be connected by inserting a connecting member through the connecting holes (631) formed on both sides of the connecting part.

[0094] When in use after binding, the rotating part can be rotated to unfold the aluminum deck (1000) for use in moving the worker, and when not in use, the rotating part can be rotated to fold the aluminum deck (1000) to secure additional workspace for the worker.

[0096] Although the invention has been described with specific details such as specific components, limited embodiments, and drawings, this is provided only to aid in a more comprehensive understanding of the invention and the invention is not limited to the above embodiments, and a person skilled in the art to which the invention belongs can make modifications and variations from this description.
