[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a cross-sectional view showing a ship deck structure 1 according to an embodiment of the present invention. Fig. 2 is a cross-sectional view of the ship deck structure 1 seen from another angle. Fig. 3 is a plan view of the ship deck structure 1 seen from above Z1. Fig. 4 is a perspective view for explaining the assembly procedure of the ship deck structure 1.

[0012] As shown in Figures 1 and 2, the deck structure 1 of the ship of this embodiment is installed on steel plates 2 that constitute the ship, and is composed of metal joists 3 bolted to the steel plates 2, a height adjustment section 4 provided between the steel plates 2 and the joists 3, and deck material 5 fixed to the steel plates 2 via the joists 3.

[0013] In the following, arrows X, Y, and Z are perpendicular to one another. Arrow X is the direction connecting the bow and stern of the ship (longitudinal direction of the ship) and is referred to as the "longitudinal direction X of the ship," arrow Y is the direction perpendicular to the longitudinal direction X of the ship (width direction of the ship) and is referred to as the "width direction Y of the ship," and arrow Z is the direction perpendicular to the longitudinal direction X of the ship and the width direction Y of the ship and is sometimes referred to as the "up-down direction Z."

[0014] As shown in Fig. 2, drainage sections 6 are provided at the ends of the ship in the width direction Y. The drainage sections 6 are provided on both sides of the steel plate 2 described below in the width direction Y of the ship, and include drainage ports 61 provided at intervals in the longitudinal direction X of the ship, and a mesh section 62 supported by the deck material 5 described below and provided above Z1 the drainage ports 61 for draining water from the deck material 5 into the drainage ports 61. The drainage port 61 is provided in a cylindrical shape with its axis in the vertical direction Z.

[0015] The steel plates 2 are provided in the form of plates extending in the longitudinal direction X and width direction Y of the ship, and are configured to slope downward Z2 toward both ends of the ship in the width direction Y. Stud bolts 31 for fixing joists 3 (described later) are provided upright on the steel plates 2 at appropriate positions.

[0016] As shown in Figures 1 and 3, the joists 3 are formed in the shape of strips having a predetermined thickness. The joists 3 are provided extending in the width direction Y of the ship and spaced apart from one another in the longitudinal direction X of the ship. Furthermore, the joists 3 are provided spaced apart in their longitudinal direction (the width direction Y of the ship), and water is drained into the drain outlet 61 from spaces S (shown in Figure 3) between adjacent joists 3 in the width direction Y of the ship. In this embodiment, the joists 3 are made of stainless steel square pipes.

[0017] 1, the common joist 3 is provided with a threaded portion 30. The threaded portion 30 is configured to include a stud bolt 31 erected on the steel plate 2, a lower threaded hole (not shown) through which the stud bolt 31 is inserted, a nut 32 having an opening with a larger diameter than the lower threaded hole at a position communicating with the lower threaded hole and threaded onto the stud bolt 31, a washer 33, and a nut accommodating chamber 34 that accommodates the nut 32 and the washer 33.

[0018] Furthermore, the common joist 3 is provided with a screw hole (not shown, hereinafter sometimes referred to as "upper screw hole") into which a bolt 91 of a fixing device 9, which will be described later, is screwed.

[0019] 1 and 2, the height adjustment unit 4 is configured with a first flat member 4A and a pair of second flat members 4B, 4B provided above Z1 and below Z2 the first flat member 4A. The first flat member 4A and the second flat member 4B have holes (not shown) through which stud bolts 31 are inserted, and are configured as plates with different thicknesses. The height adjustment unit 4 is used to adjust the height position of the upper surface of the deck material 5, which will be described later, and is used by appropriately combining the first flat member 4A and the second flat member 4B depending on the gradient of the steel plate 2.

[0020] As shown in Figure 2, the deck material 5 is made of artificial wood and includes strip-shaped board materials 50 installed opposite the steel plate 2 via height adjustment parts 4 and joists 3, and a sealing structure 8 that seals between adjacent board materials 50. In this embodiment, the artificial wood that makes up the board materials 50 is a "wood-plastic recycled composite material" as defined by the Japanese Industrial Standards.

[0021] 2, the plate material 50 has an entrance recess 51 on its end surface, into which an extension piece of a fixing device 9, which will be described later, enters. The entrance recess 51 is recessed into the end surface of the plate material 50 in the width direction (width direction X of the ship), and extends in the longitudinal direction of the plate material 50 (longitudinal direction X of the ship).

[0022] 2, the seal structure 8 is configured to include a fixture 9 having a fixture bolt hole (bolt hole) and spanning between adjacent plate materials 50, a lower seal part 81 (one-side seal material) positioned below Z2 a connecting plate 90 that is part of the fixture 9 (on the side of the connecting plate 90 provided on the fixture 9 that is closer to the joist 3), and an upper silicone material 82 (other-side seal material) filled above Z1 the connecting plate 90 (on the side of the connecting plate 90 that is farther from the joist 3) with the bolt 91 screwed into the joist 3. Such a seal structure 8 is provided between adjacent plate materials 50 to connect these plate materials 50 and to absorb expansion and contraction of the plate materials 50 due to temperature and moisture absorption.

[0023] As shown in Figure 2, the fixing device 9 is composed of a connecting plate 90 having a fixing device bolt hole through which a bolt 91 is inserted, which enters each entry recess 51 in adjacent plate materials 50 to connect the adjacent plate materials 50, a bolt 91 (threaded member) which is inserted into the fixing device bolt hole and screwed into the joist 3, and a leg portion which is formed extending downward Z2 from the connecting plate 90 and is installed on the upper surface of the joist 3.

[0024] The connecting plate 90 is formed in a rectangular plate shape and is composed of a connecting body having a fixing bolt hole in the center, and a pair of extension pieces that extend in the width direction of the connecting body (the width direction Y of the ship) and enter the entry recesses 51 of each plate material 50.

[0025] The connector body is installed so as to extend in a plane including the longitudinal direction X of the ship and the width direction Y of the ship. The pair of extension pieces are configured to be bent downward Z2 at the boundary positions between the connector body and each extension piece.

[0026] The bolt 91 is configured to have a length such that its tip portion can be screwed into the floor joist 3 .

[0027] The legs include a pair of first legs and a pair of second legs.

[0028] The pair of first legs are provided contiguous with the connecting body, and extend obliquely downward Z2 toward both sides of the connecting body in the longitudinal direction (longitudinal direction Y of the ship).

[0029] The pair of second legs are provided on both sides of the fixing tool bolt hole in the width direction of the connecting part body (the width direction X of the ship), and are formed obliquely extending downward Z2.

[0030] 2, the lower seal component 81 is made of elastic soft silicone such as silicone rubber or silicone sponge. The lower seal component 81 is provided in a string-like shape and is sandwiched between adjacent plate materials 50. In this embodiment, the lower seal components 81 are provided side by side in the longitudinal direction X of the ship so that a gap is formed at the position where the bolt 91 is inserted.

[0031] 2, the upper silicone material 82 is formed by dropping a liquid silicone sealant between the adjacent plates 50 and allowing it to harden. The upper silicone material 82 buries the bolts 91 and seals the gap between the adjacent plates 50.

[0032] Next, the procedure for assembling such a ship deck structure 1 will be described with reference to FIGS.

[0033] 1, the hole portions of the second flat member 4B, the first flat member 4A, and the second flat member 4B are brought close to each other and inserted into the tip of the stud bolt 31 erected on the steel plate 2 in this order. Depending on the gradient of the steel plate 2, the first flat member 4A and the second flat member 4B may be combined as appropriate.

[0034] Next, the lower screw hole of the joist 3 is brought close to the tip of the stud bolt 31 and inserted. After this, the hole of the washer 33 is brought close to the tip of the stud bolt 31 and inserted. After this, the hole of the nut 32 is brought close to the tip of the stud bolt 31 and screwed. As the screwing progresses, the nut 32 abuts against the bottom surface 3A (shown in FIG. 1 ) of the nut accommodating chamber 34, and screwing of the nut 32 is stopped. As a result, the joist 3 is bolted (fixed) to the steel plate 2. The joists 3, while bolted to the steel plate 2, are provided at intervals in the width direction Y of the ship and are installed so that water can be drained from the spaces S between adjacent joists 3 in the width direction Y of the ship to the drain outlet 61.

[0035] Furthermore, in order to support the plate material 50, floor joists 3 that are not bolted to the steel plate 2 may be installed at appropriate positions.

[0036] Next, as shown in FIG. 4, a board 50 (hereinafter sometimes referred to as "first board 50A") is placed on the top surface of the floor joist 3.

[0037] 2, lower sealing parts 81 are placed on the upper surface of the floor joist 3, and the fixing device 9 is installed by bringing the fixing device bolt holes of the fixing device 9 close to the gaps between adjacent lower sealing parts 81. At this time, the fixing device 9 is installed by bringing the extension piece of the fixing device 9 close to the entry recess 51 of one of the boards 50A and inserting the extension piece into the entry recess 51. An adhesive (not shown) may also be interposed between the floor joist 3 and the boards 50 to fix them together.

[0038] Thereafter, the tip of the bolt 91 is brought close to the fixing tool bolt hole of the fixing tool 9 and inserted through it. The tip of the bolt 91 is screwed into the upper screw hole of the floor joist 3.

[0039] Thereafter, in the width direction Y of the ship, the plate 50 (hereinafter sometimes referred to as "another plate 50B") is installed on the opposite side of the fastener 9 from the first plate 50A. At this time, the extension piece of the fastener 9 is brought close to the entrance recess 51 of the other plate 50B, and the extension piece is inserted into the entrance recess 51 while the other plate 50B is installed.

[0040] After this, liquid silicone sealing agent is dripped between the adjacent plate materials 50A, 50B and allowed to harden. This forms the upper silicone material 82. The upper silicone material 82 seals the space between the adjacent plate materials 50A, 50B while embedding the bolts 91. This process is repeated to assemble the deck material 5.

[0041] Finally, the drainage section 6 is assembled by installing the mesh section 62 above Z1 the drainage ports 61 located at both ends in the width direction Y of the ship. This allows rainwater, water from waves, etc. to be drained from the top surface of the deck material 5, and also from the gaps S between adjacent joists 3 in the width direction Y of the ship. In this way, the assembly of the deck structure 1 for the ship is completed.

[0042] According to the above-described embodiment, the deck material 5 has a plurality of plate materials 50A, 50B (50) arranged side by side in the width direction Y (width direction Y) of the ship and extending in the longitudinal direction X (ship longitudinal direction) of the ship, and a seal structure 8 that seals between adjacent plate materials 50A, 50B (50), and the plate materials 50 are made of artificial wood. As a result, even if artificial wood is used for the plate materials 50, the seal structure 8 absorbs expansion and contraction caused by the temperature and moisture absorption of the artificial wood. As a result, the seal structure 8 can fill the gap between adjacent plate materials 50A, 50B (50).

[0043] Here, even if the sealing structure 8 deteriorates and rainwater or the like seeps into the steel plates 2 from between the plates 50A, 50B (50), the water is configured to drain from the spaces S between the adjacent joists 3 to the drainage outlets 61, so it is possible to obtain a configuration in which the water is drained without accumulating on the steel plates 2. This makes it possible to use artificial wood as a flooring material, and obtains a ship deck structure 1 that can be used for a long period of time while avoiding corrosion due to infiltration.

[0044] The deck structure also has a height adjustment unit 4 that is provided between the steel plate 2 and the joist 3 and adjusts the height of the deck material 5, the joist 3 being made of metal, and the joist 3 is inserted into a stud bolt 31 that is erected on the steel plate 2 and is bolted to the steel plate 2 via the height adjustment unit 4. This provides a configuration in which the height adjustment unit 4 allows the height of the deck material 5 to be adjusted.

[0045] The sealing structure 8 also includes a connecting plate 90 having a fastener bolt hole and spanning between adjacent plate materials 50 to connect them, a lower sealing part 81 (one-side sealing material) provided on the joist 3 side of the connecting plate 90, a bolt 91 (threaded member) inserted into the fixing bolt hole and screwed into the joist 3, and an upper silicone material 82 (other-side sealing material) filled on the side of the connecting plate 90 away from the joist 3 with the bolt 91 screwed into the joist 3. The presence of this sealing structure 8 makes it possible to fill the gap between adjacent plate materials 50A, 50B (50) and to absorb expansion and contraction caused by temperature and moisture absorption of the artificial wood plate material 50.

[0046] Although the best configurations and methods for carrying out the present invention have been disclosed above, the present invention is not limited thereto. That is, although the present invention has been particularly illustrated and described mainly with reference to specific embodiments, those skilled in the art can make various modifications to the above-described embodiments in terms of shape, material, quantity, and other detailed configurations without departing from the scope of the technical idea and purpose of the present invention.
