As this floating body, a frame body in which the inside is formed in a hollow shape by concrete or steel, or a monocoque type in which a resin foam is arranged in the frame body is known. There is also known a simple one in which floating panels formed by FRP or the like are connected by a rope or the like.

  As disclosed in Patent Document 1, the applicant of the present application has proposed that a plurality of long plate-like bodies are combined to form a frame, and a foamed resin is disposed inside the frame.

Japanese Patent No. 4143701

  However, the above conventional floating jetty is relatively light and is greatly swayed by waves.

  In order to prevent the floating pier from shaking, it is conceivable to increase the weight of the floating body. However, a heavy floating body is difficult to carry and has a low buoyancy and tends to sink.

  This invention is made | formed in view of the situation which concerns, and makes it a subject to provide the floating body structure which is lightweight and can suppress the shaking by a wave.

  The present invention is a floating body structure having a foamed resin body made of a foamed resin and a frame body surrounding the foamed resin body, wherein the bottom of the frame body is unidirectionally positioned at a substantially central portion of the bottom portion. An inverted T-shaped first ridge member extending in a long shape, and at a position having a predetermined gap on at least one side of the first ridge member, substantially parallel to the first ridge member. It has a 2nd protrusion member extended and made to protrude toward the said 1st protrusion member, and the protrusion tip piece is characterized by the above-mentioned.

  Since the above floating structure is composed of a frame body and a foamed resin body, it is lightweight. In addition, an inverted T-shaped first ridge member and a second ridge member project at a predetermined gap on at least one side facing the first ridge member at the bottom of the frame. Yes. For this reason, when the floating structure is floated on the water, water enters the gap between the first protrusion member and the second protrusion member. The first and second ridge members serve as resistors that suppress the movement of water. The water that has entered the gap between the first ridge member and the second ridge member is surrounded by the first ridge member and the second ridge member and collides with these to gradually attenuate the movement of the water. Is done. For this reason, it is possible to suppress the shaking of the floating structure due to the movement of waves and water.

  The second protrusion member is preferably formed integrally with a side plate of the frame. In this case, the floating body can have a simple configuration.

  It is preferable that the second protrusion member includes an extending portion extending downward from a bottom portion of the frame body and a protruding tip portion provided at a lower tip of the extending portion. In this case, the extension portion and the projecting tip portion can be water resistance to suppress water movement.

  It is preferable that a through hole is formed in the extended portion of the second protrusion member. When the water movement or wave energy is too large, the water that has entered the bottom of the floating body is released to the outside through the through hole. Thereby, the swing of the floating body due to excessive movement of water can be suppressed.

  It is preferable that the floating body structure is fastened by a rod-like fastening member. In this case, the rigidity of the floating structure can be increased.

  The floating body structure is preferably a floating pier. Since floating structures are less susceptible to waves and water movement, people and luggage can be placed stably.

  Since the floating body structure of this invention has a foamed resin body and a resin-made frame, it is lightweight. Moreover, since the 1st, 2nd protrusion member is protrudingly provided facing each other in the bottom part of the frame, the shaking by a wave can be suppressed.

It is a top view of the floating body arranged together.

  A floating body structure according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the floating body structure is a floating body 10 for a floating pier. The floating body 10 includes a foamed resin body 1 and a frame body 2 surrounding the foamed resin body 1. The foamed resin body 1 has a rectangular parallelepiped shape made of a foamed resin. Examples of the foamed resin used for the foamed resin body 1 include polystyrene foam, polyurethane foam, polyethylene foam, and polypropylene foam. Of these, polystyrene foam is preferable.

  The frame 2 is made of resin or metal. Examples of the resin used for the frame 2 include plastics such as polypropylene and reinforced plastics (FRP). Among them, FRP having high rigidity is preferable. As a metal used for the frame 2, a lightweight metal such as aluminum is preferable.

  As shown in FIGS. 1 and 2, the frame body 2 has a substantially rectangular shape, and an upper portion thereof is formed by joining two upper plates 21. The side part of the frame 2 is formed by a side plate 22 that surrounds the periphery of the upper plate 21 in a square frame shape. A bottom plate 23 is formed at the bottom facing the top plate 21. In the space surrounded by the upper plate 21, the side plate 22, and the bottom plate 23 of the frame body 2, the foamed resin body 1 is accommodated with almost no gap. The vertical size of the frame 2 is 200 cm, and the horizontal size is 100 cm. The thickness size of the portion of the frame body 2 in which the foamed resin body 1 is accommodated is 20 cm.

  A first ridge member 3 and a second ridge member 4 project downward from the bottom plate 23 of the frame body 2. The first ridge member 3 is elongated in one direction at a substantially central portion of the bottom plate 23. The first ridge member 3 has an inverted T-shape, and includes an extending portion 30 that extends downward, and a protruding tip piece 31 that protrudes from the lower end of the extending portion 30 to both sides in the horizontal direction.

  The second ridge member 4 has an L-shape, and has an extending portion 40 that extends downward, and a protruding tip piece 41 that protrudes to one side in the horizontal direction at the lower tip of the extending portion 40. The extending portion 40 of the second protrusion member 4 is formed integrally with the side plate 22 at the lower part of the four side plates 22 surrounding the four directions.

  As shown in FIGS. 1 and 3, a projecting tip piece 41 projecting toward the first projecting member 3 is provided at the lower end of the rectangular frame-shaped extending portion 40 of the second projecting member 4. Yes. Moreover, the extending part 40 of the 2nd protrusion member 4 has the through-hole 43 formed in two places toward each direction of four directions. The second ridge member 4 is disposed at a position where a predetermined gap 8 is opened on both sides facing the first ridge member 3. The through-hole 43 plays a role of escaping a part of the water that has entered the gap 8 between the first and second protrusion members 3 and 4 to the outside in the case of a large wave. The second ridge member 4 extends in one direction of the bottom plate 23 in parallel with the first ridge member 3. The protruding tip piece 41 of the second protruding member 4 faces the protruding tip piece 31 of the inverted T-shaped first protruding member 3.

  As shown in FIG. 1, the protrusion amount T from the bottom plate 23 of the 1st protrusion member 3 and the 2nd protrusion member 4 is 10 cm. The width H1 of the protruding tip piece 31 of the first protrusion member 3 is 10 to 15 cm. The width H2 of the protruding tip piece 41 of the second protrusion member 4 is 5 to 10 cm.

  In manufacturing the floating body 10, the side plate 22 of the frame body 2 and the second protrusion member 4 are integrally formed. The bottom plate 23 of the frame 2 and the first protrusion member 3 are integrally formed. The periphery of the bottom plate 23 is welded to the center of the inner surface of the side plate 22 of the frame 2. From the opening above the frame body 2, the resin foam 1 having substantially the same shape as the frame body 2 is accommodated, and the foamed resin body 1 is placed on the bottom plate 23. After housing the resin foam 1, the upper plate 21 of the frame body 2 is covered and the upper plates 21, the upper plate 21 and the upper peripheral edge of the side plate 22 are welded together.

  As shown in FIGS. 2 and 3, the floating body 10 is fastened with a metal brace 60 in order to increase rigidity. The metal brace 60 is a rod-shaped fastening member. The four corners of the floating body 20 have a stepped shape, and substantially L-shaped metal fittings 62 are provided at the notched corners. Four metal braces 60 are extended in the vertical and horizontal directions of the floating body 10. Each metal brace 60 penetrates the vicinity of the outer periphery of the floating body 10 and tightens the floating body 10. Both end portions of the metal brace 60 are inserted into through holes formed in the substantially L-shaped metal fitting 62 and fastened with nuts 63.

  Only one floating body 10 may be used to form the floating pier 5, or a plurality of floating bodies 10 may be connected to form the floating pier 5. In the case where the floating pier 5 is formed by connecting a plurality, the direction of the extending direction of the first and second ridge members 3 and 4 may be directed to the connecting direction as shown in FIG. 4 (a)) may be directed in a direction orthogonal to the connecting direction (FIG. 4B). In connecting a plurality of floating bodies 10, the ends of the metal braces 60 of adjacent floating bodies 10 are joined together. Moreover, you may connect the some floating body 10 using a rope and a fixing metal fitting. For example, the floating pier 5 may be fixed with a rope to the opposite shore, or may be stopped at a predetermined water surface by dropping a kite in water.

  Since the floating body 10 of the present embodiment includes the resin frame body 2 and the foamed resin body 1, it is lightweight. The bottom 1 of the frame 1 has an inverted T-shaped first protrusion member 3 and a second protrusion member 4 with a predetermined gap 8 formed on at least one side facing the first protrusion member 3. Is protruding. For this reason, when the floating body 10 floats on the water, water enters the gap 8 between the first ridge member 3 and the second ridge member 4. The water is surrounded by the first ridge member 3 and the second ridge member 4, and the water collides with these to attenuate the movement of the water. For this reason, the shaking of the floating body 10 by the motion of a wave or water can be suppressed.

  In this embodiment, although the 2nd protrusion member 4 is arrange | positioned at the both sides of the 1st protrusion member 1, it may be arrange | positioned only at one side. Moreover, although the 2nd protrusion member 4 is integrally formed in the lower part of the side plate 22 of the frame 2, it may be formed separately from the side plate 22. FIG. The second ridge member 4 only needs to be disposed in parallel with a predetermined gap 8 between the second ridge member 4 and, for example, is disposed closer to the center of the bottom plate 23 than the side plate 22. May be.

  Further, the first and second protrusion members 3 and 4 extend in the longitudinal direction of the frame body 2. For this reason, the area of the part which water collides in the bottom part of the floating body 10 can be ensured large. Therefore, the effect of suppressing the movement of water and water that has entered the bottom of the floating body 10 is high. On the other hand, the first and second protrusion members 3, 4 may extend in the short side direction orthogonal to the longitudinal direction of the frame 2. Even in this case, waves can be suppressed.

  In addition, the planar shape of the floating body 10 is rectangular, but may be square. In this case, the wave suppressing effect is substantially the same regardless of which direction the first and second protrusion members 3 and 4 are directed.

  The water floating structure of the present invention can be used for floating piers, water walkways, etc., as well as various water applications such as water piers, water flower beds, fishing berths, and water work tables.
