Description

  The present invention relates to an antifouling panel member connection structure, an antifouling panel, a structure on which the antifouling panel is installed, and a connecting member for an antifouling panel, and particularly, for example, by attaching a plurality of antifouling panel members to a wall surface in contact with seawater. The present invention relates to an antifouling panel member connection structure, an antifouling panel, a structure on which the antifouling panel is installed, and a connecting member for the antifouling panel, which are connected to form an antifouling panel that prevents adhesion of marine organisms.

  Marine organisms such as mussels and barnacles adhere to the wall surface of the structure in contact with seawater, but such adhesion of marine organisms may be a problem. For example, power plants use seawater as cooling water, but if marine organisms adhere to the waterway (seawater channel) for drawing in seawater, the water intake flow rate may decrease, causing normal functions of the seawater channel. Will be disturbed. Therefore, many techniques have been proposed in order to prevent marine organisms from adhering to the wall surface in contact with seawater. Among them, as a technology to prevent the attachment of marine organisms without generating harmful substances, the organic material is decomposed by generating oxygen by electrolyzing the seawater using an anode sheet attached to the wall in contact with the seawater. Therefore, the technology that prevents the attachment of marine organisms is considered promising. An example of such a technique is disclosed in Patent Document 1.

Patent Document 1 discloses a marine organism in which an anode forming plate (anode sheet) is mounted on the surface of an insulating material, and a plurality of cathode forming strips extending in the flow direction of the intake channel are mounted on the back side of the insulating material. A marine organism adhesion prevention device is disclosed in which an adhesion prevention plate is disposed on the inner wall surface of a water channel, and an anode-forming plate-like body and a cathode-forming belt-like body are electrically joined to an external DC power source. In the technique of Patent Document 1, the marine organism adhesion prevention plate is composed of a plurality of composite plates (antifouling panel members). Each of these composite plates includes a panel-like titanium plate comprising a main body part, an upper overlapping part and a lower overlapping part, an insulating material disposed on the back surface of the main body part and the lower overlapping part of the panel-like titanium plate, It consists of a long stainless steel plate arrange | positioned through the insulating material at the end of the titanium plate. The long stainless steel plate has a protruding portion protruding from the lower overlapping portion of the panel-like titanium plate, and the insulating material is an insulating resin arranged in the fixed portion and a foam arranged in the other portion. It consists of materials.
Japanese Patent No. 4256319 [A01M 29/00]

  In the technique of Patent Document 1, the composite plate is fixed to the inner wall surface of the intake channel by driving anchor bolts to both ends of the fixed portion of the composite plate in a state where the upper and lower overlapping portions of the panel-like titanium plate are overlapped. The electrical conductivity between adjacent panel-like titanium plates (and thus the whole anode sheet) is to be secured. However, in the technique of Patent Document 1, since only the both side ends of the overlapping portion of the panel-like titanium plate are pressed by the anchor bolts, floating or gaps are easily generated in the overlapping portion between the anchor bolts. , There is a risk that stable current conduction cannot be ensured. For example, if the panel-like titanium plate is bent due to construction failure or the like, and the upper and lower overlapping portions are not firmly overlapped with each other, it is not possible to secure stable electrical conductivity. For this reason, in actual construction, it may be necessary to perform spot welding between the upper and lower overlapping portions in order to ensure stable electrical conductivity, and this work takes time and effort.

  Furthermore, since the titanium bar is tightened with bolts and nuts using a conductive titanium bar to connect the titanium plates to each other, the tightening may be loosened after a long period of time. In this case, the surface contact between the overlapping portions of the panel titanium plate cannot be properly maintained.

  Therefore, in the technique of Patent Document 1, appropriate surface contact between the upper and lower overlapping portions of the panel-like titanium plate cannot be maintained over a long period of time, that is, the conductivity of the anode sheet is stable over a long period of time. May not be maintained.

  Therefore, a main object of the present invention is to provide a novel antifouling panel member connection structure, an antifouling panel, a structure on which the antifouling panel is installed, and a connecting member for the antifouling panel.

  Another object of the present invention is to provide an antifouling panel member connection structure, an antifouling panel, and a structure in which the antifouling panel is installed, which is simple in construction and can stably secure the conductivity of the anode sheet over a long period of time.

The interval between the panel members 12 is preferably equal to or slightly larger than the width of the protruding portion 34 of the connecting member 14. Then, the antifouling panel 16 is formed over the entire construction portion by sequentially connecting the panel members 12 with the connecting member 14 in the manner described above.

  At this time, as shown in FIG. 10, the panel members 12 are connected to the cathode-equipped connecting member 42 (14) at a predetermined interval with respect to the connecting direction, for example, at a ratio of about one to the five panel members 12. Use to connect. The cathode-equipped connecting member 42 is formed in the same manner as the above-described connecting member 14 except that the cathode body 44 is embedded in the member main body 30. Will not be described.

  Briefly described, as shown in FIGS. 11 and 12, the cathode-equipped connecting member 42 includes a cathode body 44 embedded in the member main body 30, and seawater using an anchor bolt 46 and a nut. Anchored to the wall surface of the road 102. The cathode body 44 is formed in a long rectangular flat plate shape from a metal such as stainless steel, and extends over the entire length of the member body 30 in the width direction. The cathode-side conductor is connected to the end of the cathode body 44 in the width direction and the anchor bolt 46. The width of the cathode body 44 (the length in the connecting direction of the connecting member 42) is, for example, 30 mm, and the thickness thereof is, for example, 3 mm. Further, the through hole 36 is enlarged in a portion above the cathode body 44 so as to ensure insulation between the anode element 32 and the anchor bolt 46. Furthermore, in this embodiment, as shown in FIG. 10, a protrusion 46a is formed on the head of the anchor bolt 46 so as to protrude from the surface of the connecting member 42 having a cathode. This protrusion 46a is not necessarily formed, but seawater can be electrolyzed more efficiently by the portion protruding from the surface acting as a cathode.

  In this way, when the antifouling panel 16 is formed over the entire construction portion, the anode 18 formed on the surface of the antifouling panel 16 is connected to the positive electrode of the DC power supply device 104 installed outside. By connecting the negative electrode of the DC power supply device 104 to the cathode-side conductor, the installation work of the antifouling system 100 in the seawater channel 102 is completed.

  As described above, according to this embodiment, the connecting member 14 is arranged so as to straddle the adjacent panel members 12, and the connecting member 14 is pressed against the surface side of the panel member 12 and anchored to the wall surface. The anode element 32 of the connecting member 14 can be electrically connected to the anode element 22 of the panel member 12 to ensure the electrical conductivity between the anode elements 22 of the adjacent panel members 12. That is, since it is not necessary to perform spot welding or the like in order to ensure the conductivity between the anode elements 22 of the adjacent panel members 12, the antifouling panel 16 can be formed by simple construction. .

  In addition, since the connecting member 14 is pressed against the surface side of the panel member 12 so that the anode elements 22 and 32 are electrically connected, the panel member 12 does not expand in the surface direction due to a change in the temperature of seawater. Even when contracted, the contact portion between the anode element 22 of the panel member 12 and the anode element 32 of the connecting member 14 is caused to follow the expansion and contraction of the panel member 12, so that the anode element 22 of the panel member 12 and the anode element 32 of the connecting member 14 are. It is possible to ensure the conductivity between the two. Therefore, the conductivity of the anode body 18 can be stably ensured over a long period of time.

  Furthermore, according to this embodiment, since the anode element 32 is attached to the member main body 30 so as to be wound up to the back side of the member main body 30, the tightening force of the anchor bolt 40 acts on the connecting member 14. The anode element 32 of the connecting member 14 is uniformly pressed against each of the anode elements 22 of the adjacent panel members 12 and brought into surface contact. Furthermore, since the surface edge part of the panel member 12 is covered with the connection member 14, and the edge of the anode element 22 is not exposed in seawater, it is also possible to prevent the anode element 22 from dripping. Therefore, according to this embodiment, the conductivity of the anode body 18 can be secured more stably.

  Furthermore, according to this embodiment, the stepped portion 26 having the surface height lower than that of the other stepped portion is formed at the end of the connecting direction of the panel member 12, and straddles the stepped portion 26 of the adjacent panel member 12. Since the connecting member 14 is arranged, it is possible to prevent the connecting member 14 from protruding above the panel member 12 by, for example, aligning the heights of the panel member 12 and the connecting member 14. Therefore, the connection member 14 does not obstruct the flow of seawater after construction, or is reduced.

  In the above-described embodiment, the panel members 12 are connected to each other using the connecting member 42 having a cathode, at a predetermined interval in the connecting direction, for example, at a ratio of about one to the five panel members 12. However, it need not be limited to this. For example, when the construction length of the antifouling panel 16 is short, the cathode-equipped connecting member 42 can be omitted as appropriate, or the cathode-equipped connecting member 42 may be used at a higher rate.

  Furthermore, the cathode-equipped connecting member 42 is configured by embedding the cathode body 44 inside the member main body 30, but is not limited thereto. As an example, although not shown, a groove extending in the width direction is formed on the surface of the flat plate portion 24 of the panel body 20, and an insulator such as a rubber lining is provided on the anode element 22 attached to the inner surface of the groove. The cathode body 44 may be provided on the insulator. For example, the cathode body 44 is fixed to the flat plate portion 24 using fixing means such as an insulating screw or rivet. Alternatively, the cathode body 44 may be fitted and fixed to the panel body 20 by forming the groove in a tapered shape and forming the cathode body 44 in a trapezoidal cross section.

  Further, in the above-described embodiment, the leading panel member 12 is anchored to the wall surface of the seawater channel 102 using the anchor bolt 38, and then the panel member 12 that is followed by the anchor bolt 38 is fixed at a certain interval. A procedure of using the anchor bolt 40 to anchor the connecting member 14 provided so as to straddle the adjacent panel member 12 to a predetermined position on the wall surface of the sea water channel 102. However, it is not necessary to be limited to this. For example, the leading panel member 12 is anchored to the wall surface of the sea channel 102 using the anchor bolt 38, and then the connecting member 14 is temporarily fixed to a predetermined position on the wall surface of the sea channel 102 using the anchor bolt 40. Then, after anchoring the succeeding panel member 12 to a predetermined position on the wall surface of the sea water channel 102 using the anchor bolt 38, the anchor bolt 40 is tightened and the connecting member 14 is pressed against the panel member 12. Installation work may be performed.

  Furthermore, in the above-described embodiment, the step portions 26 extending in the same direction as the surface direction of the flat plate portion 24 are formed at both ends in the connecting direction of the panel member 12, but it is not necessary to be limited to this.

  For example, referring to FIG. 13, in connection structure 10 according to another embodiment of the present invention, stepped portion 26 of panel member 12 is made thicker toward the edge of panel member 12. That is, on the surface of the step portion 26, an inclined surface 26 a is formed that has a predetermined upward slope in a direction from the flat plate portion 24 side toward the edge of the panel member 12. Further, the member main body 30 of the connecting member 14 is also made thicker toward the end edge of the connecting member 14. That is, inclined surfaces 30 a are formed on the back surfaces of both end portions of the member main body 30, with a predetermined upward slope in a direction from the protruding portion 34 side toward the end edge of the connecting member 14.

  As shown in FIG. 13, when the panel members 12 are connected to each other by the connecting member 14 and attached to the wall surface of the sea channel 102, first, the panel members 12 are arranged at a predetermined interval, and the anchors are placed on the wall surface of the sea channel 102. Stop. And the connecting member 14 is arrange | positioned so that the inclined surface 30a of the member main body 30 may follow the inclined surface 26a of the level | step-difference part 26 ranging over the level | step-difference part 26 of the adjacent panel member 12. FIG. Then, the anchor bolt 40 is inserted into the through hole 36 of the connecting member 14, and the connecting member 14 is anchored to the wall surface of the seawater channel 102, whereby the anode element 32 attached to the inclined surface 30 a of the member main body 30 is removed. Then, the anode element 22 affixed to the inclined surface 26 a of one panel member 12 and the anode element 22 affixed to the inclined surface 26 a of the other panel member 12 are brought into surface contact. By doing so, the stepped portion 26 of the panel member 12 and the connecting member 14 are fitted to each other, and electrical conductivity between the anode element 22 of the panel member 12 and the anode element 32 of the connecting member 14 is ensured.

  According to the embodiment shown in FIG. 13, the stepped portion 26 of the panel member 12 is given a gradient, and the member main body 30 of the connecting member 14 is given a gradient so that they fit each other. Positioning when anchoring to the wall surface of the seawater channel 102 is facilitated, and displacement of the connecting member 14 in the connecting direction is prevented.

  Here, especially in underwater construction, the light is only a light source such as a headlamp, and the field of view is not good, so it is difficult to finely adjust the positioning when attaching the connecting member 14, but the implementation shown in FIG. According to the example, since the positioning of the connecting member 14 becomes easy, the antifouling panel 16 can be formed by simpler construction.

  Further, as described above, one panel member 12 is anchored to the wall surface of the sea channel 102 using the anchor bolt 38, and then the connecting member 14 is fixed to the predetermined wall surface of the sea channel 102 using the anchor bolt 40. After temporarily fixing in position and then temporarily placing the other panel member 12 at a predetermined position on the wall surface of the sea channel 102, the anchor bolt 40 is tightened to press the connecting member 14 against the panel member 12, and then Even when the installation work is performed in the procedure of anchoring the other panel member 12 to the wall surface of the sea water channel 102 using the anchor bolt 38, the fastening force of the anchor bolt 40 acts on the connecting member 14. The other panel member 12 enters the back side along the inclined surface 30a of the connecting member 14, and is less likely to shift in the connecting direction after the anchor bolt 40 is tightened. It is possible to reduce the possibility that member 12 is placed inclined.

  Further, in the above-described embodiment, the anode element 32 is attached to the member main body 30 so as to be wound up to the back surface side of the member main body 30, and the portion extending to the back surface side is brought into surface contact with the anode element 22 of the panel member 12. However, the present invention is not limited to this.

  For example, referring to FIG. 14, in connection structure 10 according to another embodiment of the present invention, connection member 14 is provided with a conductor 48 that penetrates connection member 14 in the front and back direction (that is, in the thickness direction). . The conductors 48 are, for example, rivets and screws, and are provided on both sides of the connecting member 14 in the connecting direction. For example, in this embodiment, two conductors 48 are arranged in a line in the width direction of the connecting member 14 on each side of the connecting direction of the connecting member 14. The conductor 48 penetrates through the member main body 30 and the anode element 32 attached thereto, and is electrically connected to the anode element 32 on the front surface side of the coupling member 14, and on the back surface side of the coupling member 14, It protrudes from the back surface of 30 and is pressed against the anode element 22 of the panel member 12. For this reason, if the conductor 48 is provided in the vicinity of the anchor bolt 40 (through hole 36), the conductor 48 is more strongly pressed against the anode element 22 of the panel member 12. It becomes possible to secure stably. The anode element 32 is attached to the member main body 30 so as to cover the entire surface of the member main body 30 and the both end portions thereof are wound up to the side surface side of the member main body 30.

  As shown in FIG. 14, when the panel members 12 are connected to each other by the connecting member 14 and attached to the wall surface of the sea channel 102, first, the panel members 12 are arranged at a predetermined interval, and the anchors are placed on the wall surface of the sea channel 102. Stop. And the connection member 14 is arrange | positioned ranging over the level | step-difference part 26 of the adjacent panel member 12. FIG. Then, the anchor bolt 40 is inserted into the through hole 36 of the connecting member 14, and the connecting member 14 is anchored to the wall surface of the seawater channel 102, so that the conductor 48 of the connecting member 14 is stepped on the one panel member 12. The anode element 22 affixed to the part 26 and the anode element 22 affixed to the step part 26 of the other panel member 12 are pressed against and brought into contact with each other. In this way, the anode element 32 of the connecting member 14 is electrically connected to the anode element 22 of the panel member 12 via the conductor 48, and the anode element 22 of the panel member 12 and the anode element 32 of the connecting member 14 are Is ensured.

  In the embodiment shown in FIG. 14 as well, since there is no need to perform spot welding or the like, the antifouling panel 16 can be formed by simple construction, and the anode element 22 of the panel member 12 and the conductivity of the connecting member 14 can be formed. Since the contact portion with the body 48 can follow the expansion and contraction of the panel member 12, the conductivity of the anode body 18 can be ensured stably over a long period of time.

  Furthermore, since it is not necessary to extend the anode element 32 to the back surface side of the member main body 30, and the usage amount of the anode element 32 can be reduced, the cost of the connecting member 14 can be reduced.

  In the embodiment shown in FIG. 14, a rivet having an elliptical cross section at the end (head) is used as the conductor 48, but the cross sectional shape of the end of the rivet is not particularly limited, and is a hemispherical shape. It may also be formed in a disk shape. The same applies hereinafter.

  Further, in the embodiment shown in FIG. 14, two conductors 48 are provided on both sides in the connecting direction of the connecting member 14. However, the present invention is not limited to this. Any number of conductors 48 may be provided.

  Further, in the embodiment shown in FIG. 14, the anode element 32 is attached to the member main body 30 so as to cover the entire surface of the member main body 30 and the both ends thereof are wound up to the side surface side of the member main body 30. It is not necessary to cover the entire surface and side surfaces of the member main body 30 with the anode element 32, and the anode element 32 only needs to cover the surface of the member main body 30 to a position where the conductor 48 is provided.

  Furthermore, although illustration is omitted, it goes without saying that the cathode body 44 may be embedded in the member main body 30 of the connecting member 14 of the embodiment shown in FIG. 14 and used as a connecting member having a cathode. In this case, care is taken so that the cathode body 44 and the conductor 48 do not come into contact with each other.

  Furthermore, in the above-described embodiment, a stepped portion 26 having a lower surface height than the others is formed at the connection direction end of the panel body 20 of the panel member 12, and straddles the stepped portion 26 of the adjacent panel member 12.

The portion is made thicker toward the edge of the panel member 12. That is, an inclined surface 24 a having a predetermined upward slope in the direction toward the edge of the panel member 12 is formed at the surface end portion of the flat plate portion 24. Further, the member main body 30 of the connecting member 14 is also made thicker toward the end edge of the connecting member 14. That is, inclined surfaces 30 a are formed on the back surfaces of both end portions of the member main body 30, each having a predetermined upward slope in a direction from the protruding portion 34 side toward the end edge of the connecting member 14. Although it is not always necessary to provide a gradient to the end surface of the flat plate portion 24 and a gradient to the rear surface of the end portion of the member main body 30, as described above, by doing so, the connecting member 14 is connected to the sea channel 102. Positioning when anchoring to the wall surface is facilitated, and further, displacement of the connecting member 14 in the connecting direction can be prevented.

  As shown in FIG. 15, when the panel members 12 are connected to each other by the connecting member 14 and attached to the wall surface of the sea channel 102, first, the panel members 12 are arranged at a predetermined interval, and the anchors are placed on the wall surface of the sea channel 102.

Although formed in a substantially reverse convex shape, the shape of the connecting member 14 is not particularly limited, and may be formed in a trapezoidal cross section or a rectangular flat plate shape. Further, it goes without saying that any shape of the connecting member 14 may be used as a cathode-equipped connecting member by embedding the cathode body 44 in the member main body 30.

  As an example, as shown in FIG. 17, the anchor accommodating portion 50 may be formed in the connecting member 14. The anchor accommodating portion 50 is a circular recess in a top view in which the vicinity of the center of the surface of the member main body 30 is recessed, and is provided at a position corresponding to the through hole 36. When the panel members 12 are connected to each other by the connecting member 14 and attached to the wall surface of the seawater channel 102, the head portion of the anchor bolt 40 inserted into the through hole 36 of the connecting member 14 is accommodated in the stepped portion 50. By carrying out like this, since the head of anchor bolt 40 used for anchoring of connecting member 14 does not protrude from the surface of connecting member 14, obstruction of the flow of water after construction is reduced, and the landscape is also improved. .
