  As described in Patent Document 1, in order to support the load of a deck (vehicle deck) having an area (vehicle area) on which an automobile is loaded, it is necessary to arrange a plurality of pillars in the bow-stern direction.

  However, when pillars are placed on the hull centerline, the same number of car trains must be placed on the port side and starboard side in consideration of the load balance on the hull. A passage with a predetermined width had to be secured on both sides of the row, and a passage with a predetermined width had to be formed on both sides of the pillar in the center of the hull.

  Therefore, there is a problem that the space for two or more passages must be secured in the center of the hull, resulting in a wide ship width and a lack of freedom in hull design.

  The present invention has been made in view of such problems, and an object thereof is to provide a vehicle deck structure and a vehicle ferry capable of improving the degree of freedom in hull design while observing the ship inspection knowledge. .

According to the present invention, it comprises a plurality of parking areas for parallel parking of vehicles in the stern direction, a passage formed between the adjacent parking areas, and a pillar disposed in at least one of the passages, The center line in the fore-and-aft direction of the pillar is set so as not to coincide with the center line of the passage, and the pillar is either left or right so as to secure a passage width through which a person can pass in the passage. A vehicle deck structure for a ship , which is disposed at a position close to the parking area .

Further, according to the present invention, a plurality of parking areas in which vehicles are parked in parallel in the stern direction, a passage formed between the adjacent parking areas, and a pillar disposed in at least one of the passages, A center line of the stern direction of the pillar is set so as not to coincide with a center line of the passage, and the pillar has left and right sides to ensure a passage width through which a person can pass in the passage. An automobile ferry having a ship's vehicle deck structure disposed at a position close to any of the parking areas is provided.

In the vehicle deck structure and automobile ferry described above, the pillar may have a flat shape in which the width in the bow-stern direction is wider than the width in the ship width direction. The pillar may have a cylindrical shape with an internal space that can be used for other purposes. Further, the pillar may be disposed at a position separated from the engine casing in the bow-stern direction.

Further, when the width of the passage in the ship width direction is Wt, the lateral width of the pillar in the ship width direction is Wp, and the passage width is Ww, the relationship may be Wt = Wp + Ww. The passage width is, for example, 60 cm or more.

  According to the vehicle deck structure and automobile ferry of the ship according to the present invention described above, by setting the center line of the head and tail direction of the pillar so as not to coincide with the center line of the passage, for example, the pillar is provided at the center of the hull. Even in the case of arrangement, it is sufficient to secure a space where one passage and one pillar can be arranged, the width of the ship can be made narrower than before, and the ship inspection knowledge is observed. However, the degree of freedom in hull design can be improved.

  As shown in FIGS. 1 to 2A, for example, the vehicle deck structure 1 for a ship according to the first embodiment of the present invention includes a plurality of parking systems that park vehicles in parallel in the fore-and-aft direction (X-axis direction). A region 3, a passage 3 formed between adjacent parking regions 2, and a pillar 4 disposed in at least one passage 3, and a center line Cp in the stern direction of the pillar 4 is the center of the passage 3 It is set so as not to coincide with the line Ca.

  In FIG. 1, for convenience of explanation, a direction from the stern portion 1s toward the bow portion 1b is referred to as a stern direction, and this direction is set as the X axis. The direction from starboard to port is called the ship width direction, and this direction is set as the Y axis.

  The vehicle deck structure 1 is used for the vehicle deck 11 of the ship which can carry several vehicles, such as a ferry, a RORO ship, a motor vehicle special ship, for example. The vehicle deck 11 is a deck having a vehicle area (area where a vehicle is loaded). The rectangle of the alternate long and short dash line shown in FIG. 1 means a vehicle (automobile), and the longitudinal direction indicates the longitudinal direction of the vehicle.

  For example, as shown in FIG. 1, an engine casing 12, an occupant elevating means (elevator 13 and stairs 14), an outboard lamp connecting portion 15, and the like are disposed on the vehicle deck 11. The engine casing 12 is a casing that connects an engine room arranged at the lower part of the hull and a funnel arranged at the upper part of the hull, and is arranged so as to penetrate each deck. Although not shown, the vehicle deck 11 may be provided with an inboard lamp for the vehicle to travel between the upper and lower decks.

  As shown in FIG. 1, the vehicles are parked in parallel in the fore-and-aft direction (X-axis direction). Here, the case where the vehicles are parked in parallel in 8 rows is illustrated, but the present invention is not limited to this configuration, and is not limited to even rows. As shown in FIG. 2 (A), the parking area 2 (the hatched portion) where vehicles are parked in parallel is generally partitioned by a boundary line 21 such as a white line.

  A passage 3 is disposed between the parking areas 2. As shown in FIG. 1, a plurality of pillars 4 are arranged along the bow-tail direction (X-axis direction) in the passage 3 located on the hull center line. In addition, arrangement | positioning of the pillar 4 is a mere example, and although the pillar 4 is arrange | positioned in the channel | path 3 on a hull centerline in FIG. 1, it is not limited to this structure. For example, the pillar 4 may be disposed in the passage 3 at a position deviated from the hull center line, may be disposed around the opening constituting the inboard ramp, or may be disposed in the plurality of passages 3. May be.

  The pillar 4 has, for example, an H shape. Here, if the width of the pillar 4 in the bow-tail direction (X-axis direction) is the vertical width Lp, and the width in the ship width direction (Y-axis direction) is the horizontal width Wp, the pillar 4 has the vertical width Lp larger than the horizontal width Wp. It has a wide flat shape. The pillar 4 is not limited to a flat shape, and the vertical width Lp and the horizontal width Wp may have the same length, or the vertical width Lp may be narrower than the horizontal width Wp. Good.

  Further, the pillar 4 is not limited to the H shape, and may be a substantially U shape as shown in the first modification of FIG. 2B, or the second shape of FIG. As shown in the modification, it may have an I shape, may have a substantially C shape as shown in the third modification of FIG. The shape may be rectangular as shown in the fourth modification, or may be O-shaped as shown in the fifth modification in FIG.

  Also, as shown in FIG. 2A, the center line of the passage 3 in the fore-and-aft direction (X-axis direction) is the center line Ca, and the center line of the pillar 4 in the fore-and-aft direction (X-axis direction) is the fore-and-aft. Assuming that the direction center line Cp is used, the fore-and-aft center line Cp is set at a position offset by Δc with respect to the center line Ca. That is, the pillar 4 is disposed in the passage 3 at a position close to either the left or right parking area 2.

  Although FIG. 1 illustrates a state in which all the pillars 4 are offset to the right side in the passage 3, the configuration is not limited to such a configuration. For example, all the pillars 4 may be offset to the left side in the passage 3, or the pillars 4 offset to the right side and the pillars 4 offset to the left side may be mixed.

  Here, the positional relationship between the pillar 4 and the passage 3 will be described with reference to FIGS. 3 (A) to 3 (C). FIG. 3 is an explanatory view showing the relationship between pillars and passages, in which (A) shows a conventional example, (B) shows a first embodiment, and (C) shows a modification.

  As shown in FIG. 3A, in the conventional vehicle deck structure, the center line Ca of the passage 3 'and the center line Cp in the fore-and-aft direction of the pillar 4' coincide with each other. In this case, it is necessary to secure a passage width Ww through which a person can pass on the left and right sides of the pillar 4 '. Therefore, the total width Wt of the passage 3 ′ is 2 × Ww + Wp. The passage width Ww is set to 60 cm or more according to the vehicle ferry structure standard of ship inspection knowledge.

  On the other hand, in the vehicle deck structure 1 according to the present embodiment, the pillar 4 is offset with respect to the center line Ca of the passage 3 as shown in FIG. In this case, by securing a passage width Ww through which a person can pass to the left side of the pillar 4, a space of 60 cm or more defined in the vehicle ferry structure standard of ship inspection knowledge can be secured between the adjacent parking areas 2. . Therefore, the total width Wt of the passage 3 in the present embodiment is Ww + Wp, and the total width Wt of the passage 3 can be made narrower than the conventional example shown in FIG.

  In the modification shown in FIG. 3C, the pillar 4 has a relationship of the vertical width Lp = the horizontal width Wp. Also in this modification, the total width Wt of the passage 3 becomes Ww + Wp, and the total width Wt of the passage 3 can be made narrower than the conventional example shown in FIG. Comparing the first embodiment shown in FIG. 3 (B) with the modification shown in FIG. 3 (C), the first embodiment shown in FIG. Can be narrowed.

  Thus, according to the vehicle deck structure 1 according to the present embodiment, the center line Cp of the fore-and-aft direction of the pillar 4 is set so as not to coincide with the center line Ca of the passage 3. Even if the pillars 4 are arranged in the main body, it is sufficient to secure a space for arranging one passage and one pillar, and the ship width can be made narrower than before, and the hull design The degree of freedom can be improved.

  Next, a vehicle deck structure 1 for a ship according to a second embodiment of the present invention will be described with reference to FIGS. 4 to 5 (D). Here, FIG. 4 is a plan view showing the vehicle deck structure of the ship according to the second embodiment of the present invention. 5A and 5B are diagrams showing the box pillar shown in FIG. 4, wherein FIG. 5A is an enlarged view of a portion P in FIG. 4, FIG. 5B is a first modified example of the box pillar, and FIG. Modification (D) is a third modification of the box pillar. In addition, about the same component as the vehicle deck structure 1 which concerns on 1st embodiment mentioned above, the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.

  The vehicle deck structure 1 shown in FIG. 4 has a box pillar 4b. As shown in FIG. 5A, the box pillar 4b is a pillar having a cylindrical shape having an internal space that can be used for other purposes. Here, a state where a pipe 5 for supplying water to a sprinkler or a fire hydrant is inserted into the box pillar 4b is illustrated.

  Thus, by arranging the pipe 5 in the box pillar 4b, the pipe 5 that has been conventionally arranged along the hull outer plate is inserted into the box pillar 4b arranged approximately near the hull center line. Therefore, it is possible to shorten the distance of the pipe 5 and facilitate the handling.

  In addition, the internal space of the box pillar 4b is not limited to the use which arrange | positions the piping 5 which supplies water. For example, the internal space of the box pillar 4b can be used as a ventilation path, or can be used as a space for arranging electric wires and cables.

  The box pillar 4b includes, for example, an outer shell 41 that forms a cylindrical body, and a reinforcing member 42 that reinforces the outer shell 41. As shown in FIG. 5A, the outer shell 41 has, for example, a rectangular shape in which the vertical width Lp is wider than the horizontal width Wp. The lengths of the vertical width Lp and the horizontal width Wp can be arbitrarily changed according to the required strength and the number of pipes. The box pillar 4b has the same strength as the plurality of pillars 4 shown in FIG.

  For example, the outer shell 41 may have a square shape as shown in the first modified example of FIG. 5B, or a rounded rectangle as shown in the second modified example of FIG. The shape may be sufficient, and a circular shape may be sufficient as shown in the 3rd modification of FIG.5 (D).

  For example, as shown in FIG. 5A, the reinforcing material 42 is arranged in the vertical direction. Further, although not shown, a reinforcing material may be arranged in the horizontal direction as necessary. The arrangement and number of the reinforcing members 42 can be arbitrarily changed according to the strength required for the box pillar 4b. Further, as shown in FIG. 5D, the reinforcing material 42 may be omitted.

  Further, the box pillars 4b may be arranged at substantially equal intervals in the bow-stern direction (X-axis direction) with reference to the position of the engine casing 12. By disposing the box pillar 4b in this way, the vehicle deck 11 can be effectively supported.

  In addition, arrangement | positioning of the box pillar 4b is not limited to the structure shown in figure, You may make it arrange | position the box pillar 4b only in any one of the bow part 1b or the stern part 1s. Further, the arrangement of the box pillars 4b may not be based on the position of the engine casing 12.

  Further, as shown in FIG. 5A, the bow-tail direction center line Cp of the box pillar 4b is offset by Δc with respect to the center line Ca of the passage 3 in the bow-tail direction (X-axis direction). That is, the fore-and-aft direction center line Cp of the box pillar 4 b is set so as not to coincide with the center line Ca of the passage 3.

  When such a box pillar 4b is used, the lateral width Wp is wider than that of the normal pillar 4, and therefore the box pillar 4b is preferably arranged by using a part of the parking area 2. In this way, by using the box pillar 4b in which the plurality of pillars 4 are aggregated, the minimum necessary parking area 2 and passage in the portion where the box pillar 4b is not disposed (for example, the QQ line portion in FIG. 4). 3 can be used to design the ship width.

  Further, in the portion where the box pillar 4b is disposed, the bow center direction center line Cp of the box pillar 4b does not coincide with the center line Ca of the passage 3 like the pillar 4 according to the first embodiment described above. What is necessary is just to ensure the space which can arrange | position one path and one box pillar by having set.
