A through pipe for a vessel piping}

The present invention is provided in each partition wall partitioning the cabin or cargo compartment, and is applied to prevent the flame and heat from moving to other cabins in the case of fire of the cabin or cargo compartment and to protect the pipes passing through the partition walls. As related to the through-hole, more specifically, by completely blocking the conduction of heat conducted through the pipe to completely prevent the fire generated in the cabin or cargo compartment from spreading to other cabins, cargo compartments and other interior bulkheads, The present invention relates to a through-hole for ship piping that tries to extend the time that fire spreads to other cabins by blocking high-temperature conduction through the pipe.

In general, a vessel is a general term for transportation on water, and in Korea, the vessel currently handles more than 5 tons of gross tonnage by law, but in the world, the Lloyd's Register of Steel ships with a gross tonnage of 100 tons or more, adopted by ships as statistical data, are treated as ships. However, the present invention is applicable to all steel wires regardless of tonnage.

In addition, the ship includes various interior spaces such as a crew cabin, cabin, cargo compartment, engine room, control room (hereinafter, collectively referred to as "cabinet"), and the cabins are wall bulkheads and ceiling plates (hereinafter referred to as "bulk bulkheads"). It is configured to be divided into "."

Therefore, the present invention relates to a through hole for protecting various pipes penetrating the partition wall and preventing fire. First, an embodiment of a through hole that is used to penetrate a partition wall of a conventional vessel is as follows.

In the ship's piping through-hole which penetrates the partition body 101, etc., and protects the piping 200, The said pipe through hole is penetrated by the said partition body 101, and the said pipe 200 penetrates inside. It is characterized by consisting of the clearance (300).

That is, the through pipe 300 is manufactured by cutting a pipe shape of a predetermined length.

Therefore, in the case of constructing the through-tube 300, the through-pipe 300 is first penetrated by the partition body 101 and welded, and then the pipe 200 is inserted through the inside of the through-pipe 300 for construction. To finish.

On the other hand, according to the 2002 regulations of the International Maritime Safety Equipment Organization (IMO), the thermal conductivity of the pipes is extremely limited so that the flames of the cabin can spread to other cabins when the fire breaks out, and the evacuation and extinguishing time can be maximized. have.

That is, in the piping drawn out from the engine room with the highest risk of fire, the thermal conductivity of the pipe as described above is more strictly limited.

By the way, in the case of using a pipe through-hole consisting of a conventional through-pipe, the space is formed between the through-pipe and the through-pipe through which the flame and high heat generated in the fire cabin is quickly transmitted to the other cabin.

In particular, since the high heat of the flame is quickly conducted to the other cabin by the pipe, the fire rapidly spread to the other cabin had a problem.

Therefore, it is expected that such a through tube may not pass the safety regulations of the above International Maritime Safety Equipment Organization, and thus cannot be used in the future.

In addition, in the case of using the pipe through-hole consisting of the single through-pipe, there is a problem that the pipe is repeatedly collided with the inner surface of the through-pipe due to the flow of the hull during the operation of the ship frequently causes the pipe to rupture.

In addition, when the through pipe is applied to the bulkhead of the ceiling, the vertically penetrating pipe flows up and down inside the vertically penetrating pipe due to its own weight so that the connection part of the pipe easily ruptures frequently. There was also a problem that occurred.

The present invention is designed to solve the above problems, by completely sealing the pipe and the through hole with a high temperature insulation to prevent the passage of flame and to lower the thermal conductivity of the pipe through the inside of the pipe through hole to the maximum It is an object of the present invention to provide a through-hole for ship piping, which is intended to extend the time that the flame generated from the fire cabin is transferred to the other cabin to the maximum.

It is also intended to prevent the pipe from flowing inside the through hole by fixing the pipe passing through the inside of the through hole to the center of the through hole.

In addition, even if the through-hole is mounted vertically to the ceiling bulkhead, it has the purpose of preventing the pipe from flowing up and down.

The present invention for achieving the above object, in the ship's piping through-hole for protecting the pipe through the partition wall, such as the wall or ceiling partitioning between the cabin, the inside is hollow and relatively inner diameter than the outside diameter of the pipe The through tube is formed through the bulkhead body and the intermediate outer periphery is welded and fixed to the bulkhead body, the outer surface is tightly fixed to the inner surface of the through tube, the inner surface of the flame-retardant material through which the pipe is mounted It is characterized by consisting of a cylindrical insulation.

The through tube may include a pipe support tube provided on one side and a spiral portion formed on an outer side thereof, a wedge portion for holding an external appearance of the pipe which is mounted inside the pipe support tube and penetrated, and an outside of the pipe support tube. Wrapped and fastened to the inner portion of the through pipe is fastened to the inside of the through pipe is narrowed, characterized in that it further comprises a pipe fixing portion consisting of a pipe fixing cap for fixing the pipe in the center of the through pipe.

The through-hole according to the present invention, through the partition wall 11, such as a wall or ceiling partitioning between the various cabins 1 of the vessel to protect the pipe 2 through the vessel pipe through hole for protecting the partition wall 11 It is mounted through.

Accordingly, the pipe through hole according to the present invention has a hollow inside and a larger inner diameter than the outside diameter of the pipe, and penetrates the partition wall 1 so that the middle outer circumference is welded to the partition wall 1 to be fixed to the pipe 3. ) And a cylindrical heat insulating material 4 of flame-retardant (non-flammable) material through which the outer surface is tightly fixed to the inner surface of the through pipe 3 and the outer surface of the pipe 2 is closely adhered to the inner surface. .

In addition, a portion of the outer circumference of the cylindrical heat insulating material 4 is inserted and filled in the inner surface of the through pipe 3 so as to prevent the cylindrical heat insulating material 4 from flowing inside the through pipe 3. (31) is provided.

Therefore, when the pipe through hole configured as described above is used for the partition wall body, the cylindrical heat insulating material 4 made of a flame retardant (non-flammable) material is provided between the inner surface of the through pipe 3 and the outer surface of the pipe 2. The flame of the cabin in which the fire occurred is blocked from moving between the inside of the through pipe 3 and the outside of the pipe 2.

That is to prevent the heat is moved to the other compartment through the heat insulating material.

In addition, since the cylindrical heat insulating material 4 is made of a flame retardant (non-flammable) material, it can be lowered to the maximum by absorbing the thermal conductivity of the pipe 2 penetrating the inside thereof.

In other words, as the heat transferred through the pipe itself of the pipe passes through the cylindrical insulator 4, the temperature is transmitted to below the safety regulations, thereby preventing the heat of flame from one cabin from being quickly conducted to the other cabin through the pipe. .

In other words, by completely sealing between the pipe and the through pipe to prevent the movement of flames, and by lowering the thermal conductivity of the pipe through the inside of the pipe through hole to the maximum, the fire generated in one cabin is spread to the other cabin. By extending the time to the maximum, the evacuation time of the crew and the fire extinguishing time can be maximized.

Meanwhile, as illustrated in FIGS. 1 to 3, the through pipe 3 includes a pipe support tube 51 provided on one side and a spiral portion 511 formed on an outside thereof, and the pipe support tube 51. Wedge portion 52 which is mounted on the inner side of the pipe to hold the exterior and fastened to wrap around the outside of the pipe support tube 51 and pushes the wedge portion 52 into the through tube (3). It is characterized in that it further comprises a pipe fixing portion 5 consisting of a pipe fixing cap 53 for fixing the pipe in the center of the through pipe 3 while the inner diameter is narrowed.

In particular, the outer surface of the pipe fixing cap 53 is formed with a plurality of tool locking grooves 531 in which the rotating rod is inserted at equal intervals so as to easily rotate the pipe fixing cap 53.

4 is an enlarged view of a portion A of FIG. 1, wherein the wedge portion 52 has an arc surface 522 which is in close contact with the pipe 2 and an inclined surface which is inclined from the insertion side to the outside thereof. The conical body 521 having 523 is formed in a conical cylindrical shape by combining a plurality of conical bodies 521 with a spaced space portion 524. That is, the inner diameter of each conical body 521 is reduced through the gap space portion 524 so that the pipe can be received.

In addition, the inner side surface of the pipe support tube 51 is the same as the outer inclined surface 523 of each conical body 521 constituting the wedge portion 52 to facilitate the movement of the wedge portion 52. The inclined inner surface 512 is provided.

Therefore, the process of fixing the pipe through the pipe fixing part 5 will be described with reference to FIGS. 1 to 4.

First, as described above, the pipe is mounted through the inside of the cylindrical heat insulating material 4 formed inside the through pipe 3.

Next, by rotating the pipe fixing cap 53, which penetrates the outside of the wedge portion 52 and penetrates the pipe 2, is fastened to the spiral portion 511 of the pipe support pipe 51 to the center of the through pipe 3 When moved, the wedge portion 52 inserted into the inside of the pipe support tube 51 is moved to the inside of the through tube 3, and at the same time, each conical body 521 constituting the wedge portion 52 By reducing the diameter of the inner surface of the pipe 2 is to be fixed to the center of the wedge 52.

In addition, the wedge portion 52 is fixed to the inner surface of the pipe support tube 51 integrally formed with the through tube 3, so that the through tube 3, the wedge portion 52 and the pipe (2) Interconnection is fixed through the fastening movement of the pipe fixing cap (53).

Therefore, since the pipe passing through the inside of the through pipe 3 is fixed to the inside center of the through pipe 3, the pipe can be prevented from flowing inside the through pipe 3 during the operation of the ship.

On the other hand, Figure 5 shows a state in which the through-hole of the present invention is mounted on the ceiling bulkhead body, even if the through pipe 3 is mounted vertically to the ceiling bulkhead 11, the pipe 2 to the wedge 52 As it is fixed to the center of the through-pipe 3 through, due to its own weight of the pipe (2) can be prevented from flowing up or down due to sag of the bottom or shaking of the hull.

On the other hand, as shown in Figure 1, the outer periphery of the through tube 3, the heat insulating material 6 is provided to surround the outer periphery so as to prevent the external heat is conducted into the through tube (3).

Therefore, by delaying the transmission of the flame heat of the cabin in which the fire occurred to the through pipe 3 to the maximum, it is possible to delay the maximum time that the fire generated in one cabin is moved to the other cabin.

In addition, the present invention described above has been described in a state of being applied to the bulkhead of the ship, it is also applicable to the bulkhead of Daehyeon building.

The present invention as described above, completely prevents the movement of the flame by completely sealing between the pipe and the through hole, as well as to lower the thermal conductivity of the pipe through the inside of the pipe through hole to the maximum, a fire generated in one cabin It has the effect of maximizing the time to be delivered to other cabins to maximize the evacuation and extinguishing time of the crew.

In addition, the pipe is prevented from being ruptured due to the flow of the hull during operation of the ship, there is also an effect that can more stably protect the pipe.

In addition, even though the through-hole is vertically mounted on the ceiling bulkhead, the pipe is fixed to the center of the through-hole through the wedge, thereby preventing the pipe from sagging downward due to its own weight or flowing up and down due to the shaking of the hull. By doing so, there is an effect that can protect the pipe more stably.

Although the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many various obvious modifications are possible without departing from the scope of the present invention from this description. Therefore, the scope of the present invention should be construed by the claims described to include many such variations.
