Description

  The present invention relates to a ship deck structure.

  FIG. 5 is a cross-sectional view for explaining a conventional ship deck structure. In FIG. 5, 1 is a steel plate as a hull structure, 2 is a thick plate wood made of a plurality of teak materials or the like disposed on the steel plate 1, 3 is a stud bolt implanted in the steel plate 1 (welded), 4 Is a nut that can be screwed onto the stud bolt 3. The plurality of thick plate timbers 2 are fixed to the steel plate 1 by the stud bolts 3 and nuts 4, respectively. The plurality of thick plate timbers 2 constitute a wood deck disposed on the steel plate 1.

  A cutout portion 2b is formed on the upper surface side of the joint portion 2a between the respective thick plate woods 2, and the joint portion 2a is sealed with water by filling, for example, a resin sealant 5 therein. ing. In addition, a wooden plug 6 is also provided in the space where the nut 4 of each thick plate wood 2 is disposed, and water sealing in the vicinity of the stud bolt 3 is performed.

No. 7-26231

  As described above, conventionally, in order to prevent water from entering between each of the thick plate timbers 2 and the steel plate 1, the wood sealant 5 is filled with a resin sealant 5 or the like. It has been performed that the space between each plank wood 2 constituting the deck is watertight.

  However, even if the sealing as described above is performed, the thickness of the resin sealant 5 is actually increased due to cracks due to aging or the like, warpage or cracking due to heat or drying of the plank wood 2, and the like. Water enters and stays between the wooden deck (each thick wooden board 2) and the steel plate 1 from a gap between the wooden boards 2 (the joint portion 2a), and the wooden deck (each thick wooden board 2) or There was a problem that the steel plate 1 would corrode.

  Further, conventionally, in order to prevent water from entering between the wooden deck (each thick wooden board 2) and the steel sheet 1, the work of sealing the space between the thick wooden boards 2 constituting the wooden deck is watertight. (Work such as filling the notch 2b with the resin sealant 5) was necessary, but there was a problem that the construction cost of the ship deck increased due to the work.

  Furthermore, conventionally, in order to cope with the aging deterioration of the sealing agent that seals the space between the thick board timbers 2 constituting the wood deck as described above, the sealing agent 5 is filled every time a predetermined period elapses. Maintenance such as repairs was necessary, and this was a factor in increasing the ship's running cost.

  The present invention has been made paying attention to such problems of the prior art, and avoids the problem that water invades between the conventional wooden deck and the steel plate and corrodes the wooden deck and the steel plate. In addition, the work of sealing the gaps between the thick wooden pieces constituting the wooden deck, which has been conventionally performed to prevent water from entering between the wooden deck and the steel sheet, can be eliminated. The purpose of the present invention is to provide a ship deck structure that can reduce the construction cost of the deck and can reduce the running cost of the ship without requiring maintenance such as refilling of the sealant every predetermined period. And

  The deck structure of a ship according to the present invention for solving such problems is inclined so as to gradually descend from the line connecting the bow and stern and the vicinity thereof to both ends in the direction substantially perpendicular to the line. A thermally conductive plate fixed on the steel plate so as to extend in a direction intersecting the line and to be arranged along the line at a predetermined interval. It includes a plurality of joists made of a low material, and a plurality of plastic plates fixed on the joists so as to face the upper surface of the steel plate through a predetermined distance.

  In the ship deck structure according to the present invention, the joist is preferably made of a plastic material containing glass fiber.

  In the ship deck structure according to the present invention, it is preferable that the plastic plate is formed by mixing wood powder.

  In the ship deck structure according to the present invention, it is preferable that the plastic plate has a plurality of hollow portions formed therein.

  In the ship deck structure according to the present invention, a plurality of plastic plates are inclined so as to gradually descend from the line connecting the bow and stern and the vicinity thereof to both ends in the direction substantially perpendicular to the line. It fixes to the said steel plate through several joists so that the upper surface of the arrange | positioned steel plate may oppose through a predetermined distance. That is, in the present invention, since a high-strength plastic plate is used as a member constituting the surface side of the ship deck, wood is used as a member constituting the surface side (wood deck) of the conventional ship deck. Unlike the case where it is used, the members constituting the surface side of the deck can be arranged to face each other through the joist without directly fixing to the lower steel plate, that is, through a predetermined distance from the lower steel plate. It becomes possible.

  Therefore, according to the present invention, even if water enters between a plurality of plastic plates constituting the wood deck and enters between the plastic plate and the steel plate, the intruded water is a ship according to the inclination of the steel plate. Since it flows out into the sea from both ends, water does not stay between the plastic plate and the steel plate, and the steel plate is not corroded by water.

  In addition, as described above, according to the present invention, even if water enters between the plurality of plastic plates and enters between the plastic plate and the steel plate, the water remains between the plastic plate and the steel plate. In order to prevent the steel sheet from corroding due to water intruding into and staying in the gap between the wooden deck and the steel sheet, which is conventionally done, the steel sheet is not corroded by water. The work of sealing the gap at the joint between the woods constituting the deck is completely unnecessary, and the construction work of the ship deck can be made more efficient and cost-effective.

  In addition, according to the present invention, as described above, the sealing work for the gaps between the pieces of wood constituting the wood deck is completely unnecessary. Maintenance such as refilling with a sealant is not required every time the time elapses, so that the ship's running cost can be reduced.

  Further, in the present invention, when the joist is made of a material having low thermal conductivity such as a plastic material containing glass fiber, the joist is thermally deformed when a ship sails in a tropical region or the like. Therefore, it is possible to prevent the fixing state of the plastic plate to the steel plate from being weakened.

  In the present invention, when the plastic plate is made of a mixture of wood powder, while maintaining a high-grade appearance almost the same as a conventional wooden deck made of expensive teak material, etc. It is possible to construct a deck (surface side) that is less deformed and has a higher strength at a lower price.

  Furthermore, in the present invention, when a plurality of cavities are formed inside the plastic plate, the members constituting the surface side of the deck can be reduced in weight, so that the workability at the time of deck construction is further improved. It will be improved.
