Description

  The present invention relates to a vertical electrolytic apparatus.

  As an electrolyzer, a vertical electrolyzer is known in which an electrolytic cell is arranged in a vertical direction, that is, a vertical arrangement is made to save space (for example, see Patent Document 1). The vertical electrolyzer is formed by assembling a cylindrical outer cylinder in the vertical direction and inserting an electrode module from above the outer cylinder. At the time of the insertion, in order to prevent damage to the electrode module, the periphery of the electrode module is inserted with an electrode support frame. In addition, a reinforcing material is separately disposed between the electrode support frame and the outer cylinder so that the electrode module does not rattle inside the outer cylinder during the insertion.

JP 2010-222594 A

However, in the conventional vertical electrolyzer, the reinforcing material is disposed for the purpose of preventing the backlash of the electrode module, and therefore, the reinforcing material is scattered between the inner wall of the outer cylinder and the electrode support frame. Therefore, there is a vertical flow path between the inner wall of the outer cylinder and the electrode support frame, and the liquid to be electrolyzed by the vertical electrolyzer is not only inside the electrode module, but also the outer cylinder and the electrode support frame. There was also the possibility of flowing during. That is, there is a possibility of affecting the electrolysis performance.
Moreover, since the reinforcing material was installed between the outer cylinder and the electrode support frame when the apparatus was assembled, the process was complicated.

  It is an object of the present invention to provide a vertical electrolytic device that can simplify the assembly process of the vertical electrolytic device and can maintain good electrolysis performance.

  The vertical electrolysis device of the present invention is a rectangular cylinder-shaped electrode module in which a cylindrical outer cylinder and a plurality of electrode plates are stacked inside the outer cylinder, the stacking direction being the outer An electrode module disposed perpendicular to the central axis of the cylinder, a pair of first support frames sandwiching the electrode module in the stacking direction, and the pair of first supports in a direction perpendicular to the stacking direction A pair of second support frames that are fixed to the first support frame with a frame interposed therebetween, and the first support frame has a rectangular shape corresponding to an axial length of the central axis of the electrode module A first plate portion, and a plurality of first flange portions integrally formed on the first plate portion and arranged at predetermined intervals in the axial direction, wherein the second support frame is the electrode module of the electrode module A rectangular second plate portion corresponding to the length in the axial direction, and an integral type with the second plate portion A plurality of second flanges arranged at the predetermined intervals in the axial direction, and when the first flange and the second flange are combined, A circular flange having a diameter substantially the same as the inner diameter and a slightly smaller diameter is formed, introduced from one axial side of the outer cylinder, and the pair of first support frames and the pair of second The electrode module performs electrolysis on the liquid flowing between the support frames.

According to such a configuration, since the first plate portion and the first flange portion of the first support frame are integrally formed, the assembly process of the vertical electrolytic device can be simplified and the manufacturing cost can be reduced. .
In addition, the first collar part and the second collar part form a circular collar part having a diameter substantially the same as the inner diameter of the outer cylinder and a slightly smaller diameter, so that the electrode module can be used during the assembly process. Can be prevented, and rattling of the electrode module after assembly can be prevented.
Furthermore, since the first collar part and the second collar part form a circular collar part, the electrolysis performance can be affected between the inner wall of the outer cylinder and the first support frame or the second support frame. The formation of a liquid flow path can be substantially prevented, thereby improving the electrolysis performance of the vertical electrolyzer.

In the vertical electrolysis device, the outer electrolysis device is installed in at least one flange portion of the flange portions disposed above the axial center of the outer cylinder, and the flange portion and the inner peripheral surface of the outer cylinder You may have the elastic part which fills a space.
According to such a structure, the play between the collar part and the outer cylinder can be more effectively prevented by the elastic part. Moreover, the electrolysis performance of the vertical electrolyzer can be further improved by filling the gap between the collar portion and the outer cylinder with the elastic portion.

In the vertical electrolysis device, the elastic part may have an opening that allows communication between an upper part and a lower part of the elastic part in the axial direction.
According to such a configuration, it is possible to prevent the gas generated accompanying the electrolysis from accumulating inside the vertical electrolyzer, and to improve the safety of the vertical electrolyzer.

In the above vertical electrolytic device, the opening may be a notch formed in the outer periphery of the elastic part, having a width in the circumferential direction of 8 mm to 12 mm and a depth in the radial direction of 2 mm to 4 mm.
According to such a configuration, even when gas such as hydrogen gas is generated depending on the type of liquid that is electrolyzed by the electrode module while further improving electrolysis performance, it is quickly discharged to the outside of the apparatus. Therefore, it is possible to provide a vertical electrolyzer with higher performance and higher safety.

In the vertical electrolysis device, the first support frame further includes a first rib integrally formed with the first flange portion and the first plate portion adjacent to each other in the axial direction, and the second support frame includes: You may further provide the 2nd rib integrally formed with the said 2nd collar part and said 2nd board part adjacent to the said axial direction.
According to such a configuration, it is possible to prevent the deformation of the first support frame and the second support frame, increase the strength, and more effectively protect the electrode module. Therefore, the electrolysis performance of the vertical electrolyzer can be improved and the safety can be improved.

  ADVANTAGE OF THE INVENTION According to this invention, a process can be simplified in the assembly of a vertical electrolyzer, and the vertical electrolyzer which can maintain favorable electrolysis performance can be provided.

It is a perspective view of the vertical direction of the vertical electrolyzer of the embodiment of the present invention. It is a perspective view of the horizontal direction of the electrolytic cell main body of the vertical electrolyzer of FIG. It is a disassembled perspective view of the electrode support frame (a 1st support frame and a 2nd support frame) of the vertical electrolyzer of embodiment of this invention. It is a layout of the elastic part of the vertical electrolysis device of the embodiment of the present invention. It is a layout of the elastic part of the vertical electrolysis device of the embodiment of the present invention. It is an enlarged view explaining opening of an elastic part.

  The vertical electrolyzer of the present invention uses a predetermined liquid such as urea-containing water to synthesize marine organism adhesion prevention device (inorganic electrolytic synthesizer) that electrolyzes seawater or the like, ADCA (azizocarbonamide), or the like. Any liquid can be used as the liquid to be electrolyzed, such as an organic electrolytic synthesis apparatus that performs electrolysis.

A vertical electrolysis apparatus 1 according to an embodiment of the present invention will be described in detail with reference to the drawings. Here, the example which uses the vertical electrolyzer 1 for a marine organism adhesion prevention apparatus is shown. For this reason, the liquid W to be electrolyzed will be described as seawater (or salt water). Needless to say, when the vertical electrolytic device 1 is used as, for example, an organic electrolytic synthesis device, the liquid W becomes a predetermined liquid.
FIG. 1 is a perspective view in the vertical direction of the vertical electrolysis device, and is a perspective view in a state where the entire surface of a first support frame 23 described later can be seen. FIG. 2 is a horizontal perspective view of the electrolytic cell main body 2 described later.

Here, the vertical electrolysis apparatus 1 will be described as an example of an arrangement in which the vertical electrolysis apparatus 1 stands in the vertical direction, that is, in a vertical arrangement so that the central axis of the outer cylinder 7 is vertical. The liquid electrolysis (electrolysis) of the liquid W may be performed by installing the vertical electrolysis apparatus 1 in an oblique arrangement inclined by a predetermined angle from the vertical direction while disposing the lid 10 above the lower lid 8. For example, after assembling the vertical electrolysis apparatus 1 in a vertical arrangement, the vertical electrolysis apparatus 1 may be installed in an oblique arrangement to perform the operation of the vertical electrolysis apparatus 1, that is, electrolysis. Here, the oblique arrangement means a state in which the vertical electrolysis apparatus is arranged obliquely so that the central axis of the outer cylinder 7 of the vertical electrolysis apparatus 1 is inclined with respect to the horizontal plane. It is a concept including an arrangement in which the central axis is inclined by an angle of several degrees from the angle of, for example, an angle of about 5 °, that is, a substantially horizontal arrangement (substantially horizontal arrangement).
In other words, the “vertical electrolyzer” of the present invention is named “vertical”, but is installed in a vertical arrangement or an oblique arrangement (substantially horizontal arrangement) to perform electrolysis of the liquid W. It is.

As shown in FIG. 1, the vertical electrolyzer 1 includes a lower lid 8 having an inlet 9 into which seawater (or salt water) W is introduced, and an outlet 11 from which seawater (or salt water) W is discharged. The upper lid 10 and the lower lid 8 and the electrolytic cell main body 2 sandwiched and connected to the upper lid 10 from the vertical direction (axial direction DA). The pair of positive electrode rods 15 </ b> A are electrically connected to the positive electrode of an electrode module 3 described later disposed inside the electrolytic cell main body 2, and protrude vertically and upward from the upper lid 10 to the outside of the vertical electrolysis apparatus 1. Yes. The pair of negative electrode bars 15 </ b> B is electrically connected to the negative electrode of the electrode module 3, and protrudes vertically downward from the lower lid 8 to the outside of the vertical electrolysis apparatus 1. These electrode rods (the positive electrode rod 15A and the negative electrode rod 15B) serve as external terminals for electrically connecting the vertical electrolyzer 1 to an external device.
Seawater (or salt water) W flows in the vertical direction (axial direction DA) of the vertical electrolyzer 1, that is, into the inlet 9 of the lower lid 8, and flows upward in the electrolytic cell main body 2. It flows out of the vertical direction (axial direction DA) of the mold electrolysis apparatus 1, that is, from the outlet 11 of the upper lid 10. And while passing through the inside of the electrolytic cell main body 2, seawater (or salt water) W is electrolyzed by an electrode module 3 described later disposed in the electrolytic cell main body 2.

  As shown in FIG. 2, the electrolytic cell main body 2 includes a cylindrical outer cylinder 7 having a central axis extending in the vertical direction (axial direction DA) and open at both ends, and electrodes accommodated in the outer cylinder 7. A support frame (first support frame 23, second support frame 27) and the electrode module 3 are provided.

  The outer cylinder 7 is a pipe made of metal or reinforced plastic, for example. The electrode support frame 4 includes a pair of first support frames 23 and a pair of second support frames 27 made of an electrically insulating material, for example, made of reinforced plastic. The electrode support frame 4 will be described in detail later with reference to FIG.

  The electrode module 3 is a quadrangular prism-shaped electrode module in which a plurality of rectangular electrode plates 18 are stacked. The electrode plate 18 is a bipolar electrode plate in which both an anode (positive electrode) and a cathode (negative electrode) are formed on one electrode plate. Here, a bipolar electrode plate is taken as an example, but not limited to this, a monopolar electrode plate in which only one of an anode and a cathode is formed on one electrode plate may be used. Regardless of the type of electrode plate, the electrode plates are sequentially laminated in the laminating direction DL so that the anode and the cathode face each other alternately. Since electrolysis is performed by flowing seawater (or salt water) W in the direction of the central axis, the laminating direction DL is a horizontal direction, and is in a positional relationship perpendicular to the central axis, in other words, perpendicular to the axial direction DA.

  As shown in FIG. 2, the plurality of electrode plates 18 are arranged in parallel to each other at a predetermined interval by an annular spacer 21 so as not to be electrically short-circuited. The arrangement in which the plurality of electrode plates 18 are parallel to each other at a predetermined interval by the annular spacer 21 is treated as a state in which the electrode plates 18 are stacked in the embodiment of the present invention.

  The electrode module 3 is sandwiched between the pair of first support frames 23 in the stacking direction DL, and is fixed to the pair of first support frames 23 by bolts 22A and nuts 22B formed of an electrically insulating material such as plastic. Be bound. Further, the pair of first support frames 23 are sandwiched between the pair of second support frames 27 from the direction perpendicular to the stacking direction DL in the horizontal plane, and the first support frames are formed by bolts 32 formed of an electrically insulating material such as plastic. 23 and the second support frame 27 are fixed. Specifically, the screw hole 24 a formed in the end surface of the first plate portion 24 of the first support frame 23 is inserted into the through hole formed in the second plate portion 28 of the second support frame 27. By fastening the bolt 32, the first support frame 23 and the second support frame 27 are fixed.

  Thereby, in the horizontal plane, the periphery of the electrode module 3 is entirely covered by the electrode support frame 4 from the upper side to the lower side in the vertical direction, so that the electrode module 3 secured to the electrode support frame 4 is inserted into the outer cylinder 7. At this time, the electrode plate 18 can be easily inserted and assembled without worrying about damage that may be caused by contact with the inner wall of the outer cylinder 7.

  FIG. 3 is an exploded perspective view of the electrode support frame 4. The first support frame 23 is integrally formed with the first plate portion 24 and the rectangular first plate portion 24 corresponding to the length of the electrode module 3 in the axial direction DA of the central axis of the outer cylinder 7, and is axially DA. And a plurality of plate-shaped first flange portions 25 arranged at predetermined intervals along the two, and of the plurality of first flange portions 25, two adjacent first flange portions 25 and the first plate portion 24 are integrated with each other. A formed plate-like first rib 26 is provided. The length in the horizontal direction (length in the width direction) of the first plate portion 24 corresponds to the length in the horizontal direction (length in the width direction) of the electrode module 3.

  The first flange portion 25 has an outer surface (electrode module 3) of the first plate portion 24 such that the main surface of the first flange portion 25 is orthogonal to the central axis of the outer cylinder 7 and the main surface of the first plate portion 24. Is disposed on the surface opposite to the surface of the first plate portion 24 on which is disposed. The outer shape of the first flange 25 includes a first side 33 along the main surface of the first plate portion 24, a pair of second sides 34 orthogonal to the first side 33, and a first edge forming the outer periphery of the flange 14. And an external shape constituted by 35. The 1st board part 24 and the 1st collar part 25 are integrally formed, for example by adhesion | attachment.

  The first rib 26 is arranged so that the main surface of the first rib 26 is orthogonal to the main surface of the first plate portion 24 and the main surface of the first flange portion 25. The first rib 26 is integrally formed with the first plate portion 24 and the first flange portion 25, for example, by bonding. In FIG. 1, FIG. 2, and FIG. 3, two first ribs 26 are formed between adjacent first flange portions 25, but this is not limiting, and one first rib 26 is formed depending on the design. In some cases, three or more may be formed.

  By providing the first rib 26, the deformation of the first support frame 23 is prevented, and the strength of the first support frame 23 can be increased. The strength of the first support frame 23 can be increased as the number of first ribs 26 is increased, and the electrode module 3 can be protected more effectively. However, as the number of first ribs 26 is increased, the manufacturing cost increases. Therefore, in view of cost effectiveness, an appropriate number of first ribs 26 is formed.

Moreover, the 1st collar part 25 and the 1st rib 26 can be made into the plate-shaped member of the same material and thickness as the 1st board part 24, for example. In this case, since the member of the same material and thickness as the 1st board part 24 can be used, manufacturing cost can be reduced.
If the first support frame 23 is not deformed without the first rib 26 by design, and the strength of the first support frame 23 can be maintained without the first rib 26, the first support It is not necessary to form the first rib 26 on the frame 23. In this case, the number of first ribs 26 formed on the first support frame 23 is “0”.

  The second support frame 27 is integrally formed with the rectangular second plate portion 28 corresponding to the length of the electrode module 3 in the axial direction DA of the central axis of the outer cylinder 7 and the second plate portion 28, and is axially DA. And a plurality of plate-like second collar portions 29 arranged at predetermined intervals along the two, and of the plurality of second collar portions 29, two adjacent second collar portions 29 and second plate portion 28 are integrated with each other. The formed plate-shaped second rib 30 is provided. Note that the length in the horizontal direction (length in the width direction) of the second plate portion 28 corresponds to the length in the stacking direction DL (length in the horizontal direction and width direction) of the electrode module 3.

  The second flange portion 29 is configured so that the main surface of the second flange portion 29 is orthogonal to the central axis of the outer cylinder 7 and the main surface of the second plate portion 28 (electrode module 3). Is disposed on the surface opposite to the surface of the second plate portion 28 on which is disposed. The outer shape of the second flange portion 29 is along the main surface of the second plate portion 28, the third side 36 that contacts the second side 34 of the first flange portion 25, and the second edge 37 that forms the outer periphery of the flange portion 14. It is an outer shape composed of The 2nd board part 28 and the 2nd collar part 29 are integrally formed, for example by adhesion | attachment.

  The second rib 30 is disposed so that the main surface of the second rib 30 is orthogonal to the main surface of the second plate portion 28 and the main surface of the second flange portion 29. The second rib 30 is integrally formed with the second plate portion 28 and the second flange portion 29, for example, by bonding. In FIG. 1, FIG. 2, and FIG. 3, two second ribs 30 are formed between adjacent second flanges 29. However, the present invention is not limited to this, and one second rib 30 is formed depending on the design. In some cases, three or more may be formed.

  By providing the second rib 30, the deformation of the second support frame 27 can be prevented and the strength of the second support frame 27 can be increased. As the number of the second ribs 30 is increased, the strength of the second support frame 27 can be increased, and the electrode module 3 can be more effectively protected. However, since the manufacturing cost increases as the number of the second ribs 30 is increased, an appropriate number of the second ribs 30 is formed in view of cost effectiveness.

Moreover, the 2nd collar part 29 and the 2nd rib 30 can be made into the plate-shaped member of the same material and thickness as the 2nd board part 28, for example. In this case, since the member of the same material and thickness as the 2nd board part 28 can be used, manufacturing cost can be reduced.
If the second support frame 27 is not deformed without the second rib 30 by design, and the strength of the second support frame 27 can be maintained without the second rib 30, the second support frame 27 can be maintained. It is not necessary to form the second rib 30 on the frame 27. In this case, the number of the second ribs 30 formed on the second support frame 27 is “0”.

When the electrode support frame 4 is formed, that is, when the first support frame 23 and the second support frame 27 are fixed to each other, the first flange portion 25 and the second flange portion 29 have the above-described external shapes, Combined with each other, the circular flange portion 14 is substantially the same diameter as the inner diameter of the outer cylinder 7 (the diameter of the inner wall (inner peripheral surface) of the outer cylinder 7) and is slightly smaller than the inner diameter of the outer cylinder 7. Is formed automatically.
Unlike the reinforcing member that is separately installed between the outer cylinder and the electrode support frame when the vertical electrolytic apparatus is assembled as in the prior art, the flange 14 is integrally formed with the electrode support frame from the beginning. Therefore, the assembly process is simplified.

Further, since the flange portion 14 has a circular shape having a diameter substantially the same as the diameter of the inner wall of the outer cylinder 7 (inner diameter of the outer cylinder 7), the electrode module 3 is rattled inside the outer cylinder 7. It is prevented.
Further, the flange 14 substantially seals the horizontal gap between the outer cylinder 7 and the electrode support frame 4 at the position where the flange is disposed, and prevents the formation of a flow path of seawater (or salt water) W. Since it becomes a baffle plate, seawater (or salt water) W becomes difficult to flow through the gap. In other words, the formation of the flow path of the gap can be substantially prevented. As a result, seawater (or salt water) W flowing from the inlet 9 of the lower lid 8 substantially passes through the inside of the electrode module 3 surrounded by the electrode support frame 4. The electrolysis is efficiently performed by 3. That is, the electrolysis performance of the vertical electrolysis apparatus 1 can be improved.

  As shown in FIG. 1, among the plurality of flanges 14 (parts formed by combining the first support frame 23 and the second support frame 27), the uppermost flange 14 in the vertical direction includes An elastic portion 19 that fills the space between the portion 14 and the inner wall (inner peripheral surface) of the outer cylinder 7 is provided. As shown in FIGS. 4 and 5, the elastic portion 19 has an outer diameter larger than the outer diameter of the flange portion 14 and is the same as or equal to the diameter (inner diameter) of the inner wall (inner peripheral surface) of the outer cylinder 7. It has a circular plate shape (or a circular sheet shape) having a slightly larger diameter (a diameter such that the elastic portion 19 slightly contacts the inner wall of the outer cylinder 7), and a through hole 39 is formed near the center thereof. . The through hole 39 is formed in a shape such that the elastic portion 19 and the electrode support frame 4 do not interfere in the horizontal direction so that the elastic portion 19 can be easily inserted into the electrode module 3 covered with the electrode support frame 4. ing. The elastic part 19 is made of an elastic material such as synthetic rubber.

  When the vertical electrolysis apparatus 1 is assembled, the electrode module 3 fixed to the electrode support frame 4 is inserted from above the outer cylinder 7 leaning in the vertical direction, but the elastic part 19 is the uppermost flange part. 14, the insertion work can be facilitated. Further, the elastic part 19 is elastically deformed and can be brought into close contact with substantially the entire inner wall of the outer cylinder 7 (substantially the entire circumference of the inner peripheral surface) in the horizontal plane on which the elastic part 19 is arranged. Accordingly, since the elastic portion 19 fills the space between the flange portion 14 and the inner peripheral surface of the outer cylinder 7 in the horizontal plane where the elastic portion 19 is disposed, the electrolysis is performed in the gap between the outer cylinder 7 and the electrode support frame 4 described above. It is possible to more effectively prevent the formation of a flow path that can affect the performance of the.

  Here, the example in which the elastic portion 19 is installed on the flange portion 14 that is located at the uppermost position in the vertical direction is shown. However, depending on the design, the elastic portion 19 is at least above the center in the vertical direction of the outer cylinder 7. The elastic part 19 may be installed in the part 14. If the elastic part 19 is disposed below the center of the outer cylinder 7 in the vertical direction, the elastic part 19 comes into contact with the inner wall of the outer cylinder 7 to become a resistor, so that the above insertion operation is performed smoothly. However, since the elastic part 19 is installed in the collar part 14 above the center of the outer cylinder 7 in the vertical direction, the difficulty of the insertion operation can be greatly reduced.

  Moreover, you may install the elastic part 19 in the some collar part 14 above the at least center of the vertical direction of the outer cylinder 7 according to design. Since the elastic portions 19 are installed in the plurality of flange portions 14, the electrode module 3 is further prevented from rattling inside the outer cylinder 7, and the function of the baffle plate is further improved. As a result, the vertical type The electrolysis performance of the electrolyzer 1 can be further improved.

  As shown in FIG. 5, the elastic part 19 is installed and fixed to the collar part 14 by being sandwiched between the collar part 14 and the plate-shaped fixing plate 40. The flange 14 and the fixing plate 40 can be fixed by, for example, a bolt (not shown). The fixing plate 40 may be a single part or a plurality of parts as long as the elastic part 19 can be fixed to the entire flange part 14 with substantially equal pressure. Any shape such as a semi-circle can be used.

  As shown in FIG. 6, the elastic part 19 has an opening 41 that communicates the upper part and the lower part of the elastic part 19 in the vertical direction (the axial direction of the central axis of the outer cylinder 7). The opening 41 is a notch formed on the outer periphery of the elastic portion 19 and having a dimension in which the circumferential width WI is 8 mm or more and 12 mm or less, and the radial depth D is 2 mm or more and 4 mm or less. The openings 41 are provided at, for example, four locations at equal intervals in the elastic portion 19.

  When the vertical electrolysis apparatus 1 is used as an inorganic electrosynthesis apparatus or an organic electrosynthesis apparatus, an ignitable or flammable gas (such as hydrogen or oxygen) can be generated by electrolysis using the electrode module 3. The baffle part 14 and the elastic part 19 substantially block all the horizontal gaps between the outer cylinder 7 and the electrode support frame 4 at the position where the collar part is disposed, and prevent the formation of the flow path of the liquid W Thus, the liquid W substantially does not flow through the gap. However, in either case where the vertical electrolysis apparatus 1 is installed in a vertical arrangement or in an oblique arrangement, the gas moves upward toward the upper lid 10 by its buoyancy and passes through the opening 41. be able to.

That is, the gas existing in the space between the outer cylinder 7 and the electrode support frame 4 can be safely discharged from the outlet 11 of the upper lid 10 while moving upward at an early stage. Accordingly, it is possible to prevent problems (deformation, ignition, etc. of the vertical electrolysis apparatus 1) that may occur due to the accumulation of the gas inside the vertical electrolysis apparatus 1. That is, the safety of the vertical electrolytic device 1 can be improved.
The opening 41 preferably has a circumferential width WI of about 10 mm and a radial depth D of about 3 mm. Gases such as hydrogen and oxygen can be sufficiently discharged through the opening 41 having such a small size.
Here, the opening 41 has been described as a notch formed on the outer periphery of the elastic portion 19. However, if the flange portion 14 and the elastic portion 19 can sufficiently perform the function of the baffle plate, the opening 41 is not elastic. The through-hole formed in 19 may be sufficient. Further, the number of the openings 41 is not limited to four, but may be three or less or five or more.

The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes design changes and the like within a scope not departing from the gist of the present invention. .
For example, the first plate part 24 and the first collar part 25, the first collar part 25 and the first plate part 24 and the first rib 26, the second plate part 28 and the second collar part 29, the second collar part 29 and the second The member formed integrally with the plate portion 28 and the second rib 30 may have an uneven portion that facilitates fixing, may be formed integrally with different members such as screws, and from the formwork. Individual members may be integrally formed at the stage of molding.
