摘要： PURPOSE:To enable long materials to be kept with stability by forming a bulwark having a buoyant space therein on the peripheral edge of a deck member except for the stern end, a container extending longitudinally in the bulwark and an opening having a water tight lid on the rear end of the bulwark. CONSTITUTION:A section surrounded by a hull member 2 and a deck member forming of a deck 3, seat bed 5 and a rise section 31 on peripheral edge except for the stern end forms an enclosed space to provide displacement space. The upper end of the rise section 31 is folded back to form a folded-back section 33 and the lower end is connected to the upper end of a side plate 22 to provide an enclosed buoyant space 30 and form a bulwark 8. The space 30 is partitioned by a partition wall 81 so that the upper space is formed as an container 80 for receiving materials like a fishing rod. The rear end of the bulwark 8 is opened so that a water tight lid can be removably mounted thereon. Thus, the stable movement of a boat can be achieved and the long materials can be stored.

摘要： PURPOSE:To increase fatigue strength in a supplementary member fitting part and to reduce thickness increasing and reinforcing weight by performing welding via a long-sized band-plate-shaped pad plate to increase the weld zone fatigue strength at the time of welding and fitting a supplementary member to a main structural member. CONSTITUTION:The long-sized band-plate-shaped pad plate 3 is fitted to a horizontal brace 1 which is the main structural member at a continuous fillet weld zone 4 and a hand rail column 2 which is the supplementary member is fitted on said long-sized band-plate-shaped pad plate 3. A great part of a fillet welding parallel part 4a of the long-sized band-plate-shaped pad plate 3 to the horizontal brace 1 runs parallel to the variable stress direction with the exception of a fillet welding end 4b. By this method, the fillet welding parallel part 4a has the high fatigue strength and the plate thickness of material of the central part 12 of the horizontal brace 1 can be reduced.

摘要： PURPOSE:To simplify to mount a gutter and a hand rail after loaded on a block building berth by assembling the gutter and the hand rail in a body on land. CONSTITUTION:A gutter 3 and a hand rail portion (hand rial 4, fall-in preventing round bar 5, hand rail strut 6) are assembled in a body as a unit on land and both ends of the hand rail 4 are bent in 90 deg. to joint to the gutter 3 for avoiding to tie-in with piller 2 directly.

摘要： PURPOSE:To prevent resonance in a vessel by compressively supporting up and down a supporting pole via compressed gas, and changing the natural frequency of the supporting pole by adjusting the pressure of the compressed air. CONSTITUTION:Bellows-like sealing members 6, 7 which are airtight and pressure resistant are mounted between the lower outside circumference of a supporting pole 2 and the outside circumference of a base pole 3, and between the inside circumference in the lower part from a cover plate 5 of the supporting pole 2 and the inside circumference of the base pole 3 respectively. A chamber which is completely sealed by the supporting pole 2 and the base pole 3 connected to sealing members 6, 7 is formed between the cover plate 5 and a floor plate 4. Compressed gas is filled in the chamber to form a compressed gas chamber 8. A compressed gas supply hole 9 is installed in the lower wall of the base pole 3 and connected to a compressed gas supply source through a valve 10.
