Description

  The present invention relates to a waterproof protective fence installed in a coastal area, and in particular, a waterproof protective fence suitable for preventing water intrusion due to a storm surge caused by an tsunami, flood, typhoon, etc. caused by an earthquake, and a resin panel used therefor It relates to a unit connection.

  Conventionally, embankments and water-proof guard fences have been constructed along riverbanks and coasts to prevent water from entering areas where people live due to storm surges caused by tsunamis, floods, and typhoons caused by earthquakes. Yes. However, the Great East Japan Earthquake that occurred on March 11, 2011 was unable to stop a huge tsunami that exceeded the assumptions made at the time of construction, resulting in tremendous damage. For this reason, levee and waterproof fences to be constructed in the future are required to have higher levels of durability against floods and tsunamis.

  Various techniques for improving durability against floods and tsunamis have been conventionally proposed (for example, see Patent Document 1). The waterproof protective fence disclosed in Patent Document 1 is intended to improve the durability as a fence and to be quickly installed by a simple operation. The hollow part formed in this is equipped with a metal channel, and a plurality of the resin plate-like bodies are connected to each other. Since the plate-like body can be reduced in weight by using a resin as the material for the plate-like body, it is possible to construct a protective fence quickly and easily. In addition, it is possible to improve the rigidity by using a metal with high rigidity as the channel, and even if the external force transmitted to the plate-like body increases due to flooding, it is possible to suppress the amount of bending of the panel and repeat it over a long period of time. It can also be used.

  However, in the disclosed technique of Patent Document 1, since the metal channel is internally provided in the hollow portion in the resin plate-like body, the translucency cannot be ensured, and the built protection fence can Since the road is shaded, there is a problem that the surrounding area of the protective fence is always dark. Furthermore, in the disclosed technique of Patent Document 1 in which this translucency cannot be ensured, the scenery on the sea side cannot be expected, and the scenery is damaged, and the presence of a protective fence gives a feeling of blockage and pressure. It will also end up.

  Furthermore, depending on the assumed tsunami level, it may not be possible to stop with a protective fence alone. For this reason, if you overestimate the power of the protective fence, the evacuation will be delayed, and the possibility of personal injury cannot be denied. In such a case, the disclosed technique of Patent Document 1 cannot ensure translucency, so that it is impossible to visually recognize that the field of view is blocked by the protective fence and the tsunami is approaching, and evacuation is delayed. There was also a risk of it.

  Therefore, in the future, it will be necessary to build a dike that can visually check the approach of tsunamis and floods while preventing the invasion of tsunamis.

Utility Model Registration No. 3166822

  In addition, by providing translucency to the protective fence itself, the visibility is surely improved, it is also possible to evacuate by confirming the approach of tsunami and flood at an early stage, the problem that the sunlight by the protective fence is blocked, It is possible to improve the problem of a feeling of obstruction and pressure. When the protective fence is made translucent, it is generally considered that the material is composed of a resin such as acrylic resin or polycarbonate having translucency. However, such a resin is weaker than metal, and when the external force transmitted to the plate-like body due to flooding or tsunami is large, the amount of bending of the panel is increased, leading to brittle fracture.

  For this reason, when the protective fence or embankment is made of resin, even if the external force transmitted to the plate-like body is increased due to floods or tsunamis, durability is maintained for a long time without being greatly bent and broken. It was necessary to show it.

  Accordingly, the present invention has been devised in view of the above-described problems, and the object of the present invention is to provide waterproof protection capable of improving durability against floods and tsunamis while ensuring translucency.

That is, the support column 2 is formed with a groove portion surrounded by the support column web portion 21 and the support flange portions 22 and 23. This support | pillar flange part 22 is arrange | positioned toward the land side, and the support | pillar flange part 23 is arrange | positioned toward the sea side (river side). Further, as shown in FIG. 7, a through hole 65 for attaching the pressing member 5 is provided at the upper end of the column web part 21 in the column 2. The column 2 is desirably made of H-shaped steel from the viewpoint of manufacturing cost, but is not limited to this, and may be composed of a steel material having any cross-sectional shape as long as sufficient rigidity can be secured. .

  The resin panel unit connector 30 is configured by connecting a plurality of resin panel units 3. The panel unit 3 is formed in a so-called U-shaped cross section including a web 31 and flanges 32 and 33 formed at both ends of the web 31. That is, since the flanges 32 and 33 are configured to extend in the same direction with respect to the web 31, it is possible to configure such a U-shaped cross section.

  FIG. 4 is a perspective view of the resin panel unit connector 30, FIG. 5A is a side view showing only the panel unit 3, and FIG. 5B is a front view thereof. The panel unit 3 is extended in the longitudinal direction as shown in FIG. 5 (b), and its length corresponds to the interval between the columns 2. The panel unit 3 is made of a resin exhibiting translucency such as acrylic resin or polycarbonate. In the panel unit 3, the web 31 and the flanges 32 and 33 are integrally formed by, for example, a method such as injection molding or a thermal bending process of a plate-like body.

  A locking piece 34 is attached to the upper surface of the web 31 of the panel unit 3. The locking piece 34 may be provided over two near the both ends of the web 31, but is not limited to this. For example, as shown in FIG. The locking piece 34 may be affixed over substantially the entire surface excluding both ends of the upper surface of the web 31. The locking piece 34 may be extended in the longitudinal direction as shown in FIG. 5B, but is not limited to this, and is provided intermittently in the longitudinal direction. May be.

  The locking piece 34 is made of a translucent resin like the panel unit 3 and is attached to the upper surface of the panel unit 3 by, for example, adhesion or heat welding. Note that the locking piece 34 is not limited to a case where what is manufactured independently of the panel unit 3 is attached to the panel unit 3 afterwards, and may be formed integrally with the panel unit 3. Good.

  When the panel unit 3b having such a configuration is attached to the panel unit 3a, the flanges 32a and 33a of the panel unit 3a are fixed to the web 31b of the panel unit 3b. FIG. 6 is an enlarged view of the portion B showing the fixing portion in FIG. 3, but the end of the flange 32a is fixed to the web 31b of the panel unit 3b. The end portion of the flange 32a is fixed to the web 31b while being locked to the outside of the locking piece 34b. As for this flange 32a, it is desirable to adjust the position etc. of the latching piece 34b so that it may form the same plane as the flange 32b at the time of adhering. By actually forming the locking piece 34b in advance, it is possible to align the fixing position of the flange 32a, and it is also possible to prevent the displacement of the flange 32a.

  When the flange 32a is actually fixed to the web 31b by heat welding, the flange 32a may be heated by using a burner 7 or the like from the outside as shown in FIG. By disposing the locking piece 34b on the inner side of the flange 32a, it is possible to prevent the locking piece 34b from becoming a barrier when heated by using the burner 7 from the outside. Further, since the locking piece 34b is formed, it is possible to prevent the heat from escaping inward when heated by the burner 7 from the outside. In addition, when fixing the flange 32a to the web 31b, it is desirable from the viewpoint of water stoppage to be performed by heat welding, but fixing using an adhesive is desirable from the viewpoint of workability.

  Incidentally, the locking piece 34b is not limited to the case where it is arranged inside the flange 32a, but may be arranged outside the flange 32a. In particular, when the flange 32a is fixed to the web 31b with an adhesive, the fixing piece 34b can be fixed to the outer side of the flange 32a, and the fixing work can be performed while being locked. is there.

  In this way, it is possible to form a closed space in a cross-sectional view between the web 31a and the flanges 32a and 33a in the U-shaped panel unit 3a and the web 31b in the other panel unit 3b. Similarly, the panel unit 3b can also form a closed space in sectional view with the other panel unit 3n in the lower stage.

By inserting the water blocking material 71, it is possible to prevent water from entering from the gap between the column flange portions 22 and 23 and the resin panel unit connector 30 into the inside.

  Incidentally, the resin panel unit connection body 30 is not limited to the case where the individual panel units 3 are connected so that the opening having a U-shaped cross section is on the lower side, but is upside down. The panel unit 3 may be connected so that the U-shaped opening of the panel unit 3 is on the upper side.

  Further, the panel unit 3 may further include an inscribed plate in which the periphery is inscribed in the web 31 and the flanges 32 and 33 constituting the closed space. The inscribed plate 181 is made of acrylic resin, polycarbonate, or the like, and has a shape in which a notch 182 is provided at the lower end of a rectangular plate material, for example, as shown in FIG. The inscribed plate 181 has a shape that can be fitted while the upper end of the inscribed plate 181 is in contact with the web 31 and the side ends are in contact with the flanges 32 and 33. At this time, the notch 182 is made in accordance with the shape and size of the locking piece 34, so that the locking piece 34 can be prevented from becoming a barrier when fitted into the panel unit 3. can do. In addition, the inscribed plate 181 to be attached to the lowermost panel unit 3 only needs to have a rectangular cross section in which the notch 182 is not provided.

  Further, the fitting position of the inscribed plate 181 in the longitudinal direction of the panel unit 3 is provided at a location where the shearing force is concentrated. In this embodiment, as shown in FIG. 2 (a), it is desirable to correspond to the end position D of the support flange portion 22. In other words, the end position D of the support flange portion 22 can also be referred to as a panel support position D from which the panel unit 3 protrudes from a groove formed by the support web portion 21 and the support flange portions 22 and 23. It is desirable to fit the inscribed plate 181 in accordance with such a panel support position of the panel unit 3. Further, when the shape of the support column 2 and the water stop structure are different from those of the present embodiment, the location where the shear force is concentrated is not limited to the end position D of the support flange portion 22, and the inset position of the inscribed plate 181 at that time Is set according to the location where the shear force is concentrated.

  The inscribed plate 181 may be fixed to the web 31 and the flanges 32 and 33 by an adhesive, or may be fixed by heat welding.

The pressing member 5 includes a contact plate 57 that contacts the support web portion 21 of the support 2, and a press plate 56 and a stiffening plate 55 that are orthogonal to the contact plate 57. A through hole (not shown) is formed in the contact plate 57, and a bolt 59 is passed through the through hole. The front end of the bolt 59 is inserted through a through hole 65 provided in the support web portion 21 and is screwed and fixed by a nut 66 from the opposite side of the support web portion 21. The holding plate 56 is angle-adjusted so that it forms a horizontal plane when fixed, and the stiffening plate 55 forms a vertical plane when fixed. Then, the bottom surface of the pressing plate 56 is fixed so as to press the upper surface of the resin panel unit connector 30. Accordingly, it is possible to suppress the resin panel unit connector 30 from being lifted by receiving an external force such as a tsunami through the pressing plate 56.

  Incidentally, the shape of the pressing member 5 is not limited to the above-described configuration, and at least the contact plate 57 that can contact the support web portion 21 of the support 2 and the resin panel unit connector 30 from above. Any shape may be used as long as it has a pressing plate 56 that can be pressed.

  In the waterproof fence 1 having the above-described configuration, the resin panel unit connector 30 is made of a translucent resin. For this reason, it is possible to prevent the building or road from being shaded by the constructed waterproof protective fence 1 and to prevent the surroundings from becoming dark due to the presence of the waterproof protective fence 1. . Moreover, since this resin panel unit coupling body 30 can ensure translucency, it is possible to see the sea side view, so that the scenery can be improved, and the presence of the waterproof protective fence 1 exists. Therefore, it is possible to prevent a feeling of obstruction or pressure from being given. Moreover, since this resin panel unit coupling body 30 can ensure translucency, it is possible to visually confirm that a tsunami or the like is approaching without obstructing the field of view, and to start evacuation early. It becomes possible to do.

  Further, in the waterproof protection fence 1 having the above-described configuration, as shown in FIG. 10, when an external force due to a tsunami is applied from the lateral direction, a shearing force τ in the arrow direction in the figure acts. However, even when this shearing force τ is applied, the panel units 3 are firmly fixed to each other through heat welding or an adhesive, so that this can be countered, and the durability against tsunami is improved. It becomes possible. Further, since the locking piece 34 is formed, it is possible to support the flange 33 of the upper panel unit 3 locked by the locking piece 34 so as not to move.

  Further, according to the present invention, a closed space is formed in a cross-sectional view surrounded by the web 31 of each panel unit 3 and the flanges 32 and 33. In particular, the flanges 32 and 33 are disposed on the sea side. It is provided in double from the land side. For this reason, compared to the case where the wall body is configured by a single resin plate, the cross-sectional secondary moment can be increased, and even when the water pressure due to the tsunami is loaded from the lateral direction, the amount of bending deformation can be reduced. This can be countered.

  Furthermore, according to the present invention, since the panel units 3 are firmly fixed through thermal welding or adhesive, it is possible to strongly prevent water from entering the panel unit 3 due to a tsunami or flood. It becomes possible.

  Further, since the space between the panel units 3 is formed through the web 31 and the flanges 32, 33, the tsunami can be achieved while reducing the material cost as compared with the case where the panel unit 3 is formed in a solid shape. It is possible to maintain high durability against external force due to the like.

  Further, according to the present invention, the fitting position of the inscribed plate 181 in the longitudinal direction of the panel unit 3 is made to correspond to the panel support position D of the panel unit 3. In particular, the panel support position D of the panel unit 3 has a large shearing force when an external force due to a tsunami or the like is applied to the panel unit 3. On the other hand, by providing the inscribed plate 181 along the shear direction at the panel support position D, it is possible to secure a shear force transmission path. In addition, this makes it possible to increase the cross-sectional area at the panel support position D and locally improve the rigidity inside the panel unit 3. As a result, according to the present invention, it is possible to prevent the panel unit 3 from being sheared and broken even when an external force due to a tsunami or the like is applied to the panel unit 3.

As for this flange 83b, it is desirable for the position etc. of the latching piece 34a-2 to be adjusted so that it may form the same plane as the flange 83a at the time of adhering. By actually forming the locking piece 34-2 in advance, it is possible to align the fixing position of the flange 83b, and it is also possible to prevent the displacement of the flange 83b.

  After the alignment is performed in this manner, the panel units 8 are firmly fixed using heat welding, an adhesive, or the like.

  Incidentally, in the above-described example, the case where the panel unit 8a and the panel unit 8b are connected has been described as an example, but the connection with the other panel unit 8 can be similarly realized. The panel unit 8b is formed with a locking piece 34b-2 on the lower surface thereof, which is used to lock the flange 83c in the panel unit 8c at the lower stage thereof. The flange 83c is fixed. Further, the lower end of the flange 82b is fixed to the upper surface of the web 81c while being locked to the locking piece 34c-1.

  Thus, in 2nd Embodiment, it has the flange 82 extended below with respect to the web 81, and the flange 83 extended upwards, Moreover, the locking piece 34-1 is on the upper surface of the web 81, By providing the locking piece 34-2 on the lower surface of the web 81, the panel units 8 adjacent in the vertical direction can be connected to each other as described above. As a result, it is possible to form a closed space in a cross-sectional view through the web 81 and the flanges 82 and 83 between the panel units 8 having a Z-shaped cross section.

  Incidentally, in FIG. 11, the lowermost panel unit 8c is connected with a lid body 85 having a cross-sectional shape capable of forming a closed space in a cross-sectional view between the web 81c and the flange 82c of the panel unit 8c. May be. In this example, a lid 85 having an L-shaped cross section is fixed to the web 81c and the flange 82c. The lid 85 includes a face plate 86 and a face plate 87 which are orthogonal to each other, and the locking piece 34 is provided in the vicinity of the end of the upper surface of the face plate 87 in the same manner as described above.

  And when attaching such a cover body 85, the upper end of the face plate 86 is contact | abutted to the web 81c, and this is fixed. At this time, it is carried out while being locked to a locking piece 34c-2 provided in the vicinity of the end of the lower surface of the web 81c. Similarly, the right end of the face plate 86 is brought into contact with the flange 82c of the panel unit 8c to be fixed. At this time, it is fixed to the locking piece 34 formed on the upper surface of the face plate 87 while being locked.

  Similarly, with respect to the panel unit 8a in the uppermost stage, a lid 85 having a cross-sectional shape capable of forming a closed space in a cross-sectional view is connected between the web 81a and the flange 33a of the panel unit 8a. Good. In this example, a lid 85 having an L-shaped cross section is fixed to the web 81a and the flange 83a. Even in such a case, similarly, the lower end of the face plate 86 is brought into contact with the web 81a to be fixed. At this time, it is carried out while being engaged with an engaging piece 34a-1 provided in the vicinity of the end of the upper surface of the web 81a. Similarly, the left end of the face plate 87 is brought into contact with the flange 83a of the panel unit 8a to fix it. At this time, it is fixed while being locked to the locking piece 34 formed on the lower surface of the face plate 87.

  Thereby, it becomes possible to form a closed space in a cross-sectional view between the web 81, the flange 82, the flange 83 and the lid body 85 of the panel unit 8. However, the lid 85 is not limited to the L shape, and any shape can be used as long as a closed space can be formed between the web 81 and the flanges 82 and 83 of the panel unit 8 in a sectional view. Also good. Further, the method of fixing the lid 85 to the panel unit 8 is performed by either an adhesive bonding or a thermal welding method.

  By connecting a plurality of panel units 8 having such a configuration by the above-described method, the resin panel unit connecting body 40 can be configured. And the resin panel unit coupling body 40 which consists of such a structure has an effect similar to the resin panel unit coupling body 30 mentioned above.

  Of course, the panel unit 8 may further include an inscribed plate 181 in which the periphery of the web 81 and the flanges 82 and 83 constituting the closed space are inscribed.

  Moreover, in the waterproof protection fence 1 which consists of the structure mentioned above, even when the external force by a tsunami is added from the horizontal direction, between panel units 8 are firmly fixed through heat welding or an adhesive agent, and this is countered. As a result, durability against tsunami can be improved. Further, since the locking piece 34 is formed, it is possible to support the flanges 82 and 83 of the upper panel unit 8 locked by the locking piece 34 so as not to move.

  Further, according to the present invention, a closed space is formed in a sectional view surrounded by the web 81 of each panel unit 8 and the flanges 82 and 83, and in particular, the flanges 82 and 83 are on the sea side. It is provided over two from the land side. For this reason, compared with the case where the wall body is constituted by a single resin plate, the sectional secondary moment can be increased, and the amount of bending deformation can be reduced even when an external force due to the tsunami is applied from the lateral direction. It becomes possible.

  Furthermore, since the resin panel unit connector 30 is made of a translucent resin, the visibility is not obstructed, and it is possible to visually recognize that a tsunami or the like is approaching, and to start evacuation early. Of course, it becomes possible.

  The present invention is not limited to the first and second embodiments described above. A resin-made panel unit having a web, flanges formed on both ends of the web, and a locking piece provided on the web surface is connected in a vertical direction, and the above in one panel unit. Any web may be used as long as the end face of the web is fixed to the panel while the flange end of the other panel unit connected to the web is locked to the locking piece. Moreover, what is necessary is just to be able to oppose with the flange formed in the said both ends, when the closed space is mutually formed in the cross sectional view between the said panel units to connect, and when receiving a hydraulic pressure from an outer side surface.

  In addition, the present invention is applied only to prevent the invasion of tsunami and flood, but is not limited to this, and can be used to prevent the invasion of water based on any other cause. Of course.
