Description

  The present invention relates to a waterproof panel and a waterproof panel fence that prevent damage to buildings and roads in the coastal area due to tsunamis and storm surges in the coastal area due to river floods and earthquakes caused by typhoons.

  As countermeasures against typhoon floods and tsunamis caused by earthquakes, embankments and water-proof panel fences are built up along the river banks and coasts to prevent water from entering areas where people live. In the case of a waterproof panel fence, if a waterproof panel having a large area is provided, it is required to have sufficient cross-sectional rigidity because it receives a large amount of water pressure and wave pressure. In particular, since the panel portion will be broken when greatly bent, a structure having high rigidity and little bending is required.

  Various proposals have conventionally been made as techniques for improving the durability of waterproof panel fences against such floods and tsunamis. For example, in the technique disclosed in Patent Document 1, a metal channel is internally provided in a hollow portion formed inside a resin plate body having a hollow structure, and a plurality of the resin plate bodies are connected to form a panel. It is composed. By using resin as the material of the panel, the panel can be reduced in weight, and a waterproof panel fence can be quickly constructed in the event of an emergency such as a flood. Here, in a waterproof panel fence, when a general flat resin panel is used, the panel is greatly bent by an external force due to water pressure such as flood. On the other hand, the disclosed technique of Patent Document 1 is excellent in that the whole is made of resin and is reduced in weight, but is reinforced by a metal channel inside thereof to improve rigidity and suppress panel deflection. I can say that.

Utility Model Registration No. 3166822

  However, when water pressure or wave pressure is applied to the entire panel, stress is concentrated particularly on the fixed portion between the panel and the column. That is, there is a case where a stronger reinforcement is required for the fixed portion between the panel and the column than to suppress the bending of the panel. In such a case, if the hollow portion of the resin panel is uniformly reinforced with a metal channel as in the technology disclosed in Patent Document 1, it matches the rigidity of the fixed portion between the panel and the column where the highest rigidity is required. Reinforced. That is, when the reinforcement as in Patent Document 1 is performed when the shearing force applied to the fixed portion between the panel and the column is large, the panel becomes excessively strengthened near the center of the panel. Even if a hollow resin material is used to reduce the weight, the overall weight is increased due to uniform reinforcement of the metal channel. As a result, a complicated structure as a whole requires a lot of materials, which is uneconomical.

  Therefore, for the waterproof panel used as the waterproof panel fence, the area near the center of the panel has rigidity enough to suppress bending, and the fixing portion between the panel and the column has higher rigidity, and an economical structure. It was sought after.

  Therefore, the present invention has been devised in view of the above-described problems, and the object of the present invention is to provide economical waterproofing that performs necessary reinforcement at a location where stress is concentrated without excessive reinforcement. It is to provide panels and waterproof panel rails.

It is characterized by being.

  According to the first aspect of the present invention, a plurality of the panel units each having the metal hollow square pipe and the reinforcing member in the hollow portion are connected in the vertical direction. For this reason, since it is hollow, material cost is reduced as compared with the case where it is configured in a solid state. In addition to this, since the hollow square pipe is made of metal and the reinforcing member is provided inside the hollow square pipe, it is possible to maintain high durability against external force due to water pressure or wave pressure. It becomes possible. In particular, since the reinforcing member is provided at a location corresponding to a fixed portion to the support in the hollow portion of the hollow square pipe, even if stress is locally concentrated at the location due to water pressure or wave pressure, The reinforcing member can prevent breakage of the portion of the panel unit.

  According to the second invention, since the reinforcing member is inscribed in the short direction perpendicular to the direction in which the hollow square pipe is connected, the force such as water pressure or wave pressure is applied to one side of the panel unit. Can be effectively transmitted from one side to the other side. In addition, by providing the reinforcing member at a predetermined position, it is possible to reinforce the location where stress is concentrated.

According to the third invention, since the reinforcing member has a gap, when the hollow square pipe is plated or coated for rust prevention, the raw material or paint for plating is applied to the inside of the panel unit. It can be easily made to flow in and out. This is because waterproof panel fences are often installed in coastal areas, where corrosion resistance is required, and when the hollow square pipe and the reinforcing member are made of steel, it is necessary to apply plating or painting. It is.

According to the fourth invention, one or more corners of the reinforcing member are cut away, so that the corners of the hollow part of the hollow square pipe and the corners of the reinforcing member are joined together.

FIG. 6 is a cross-sectional view taken along line aa ′ shown in FIGS. 1 and 5. FIG. 4 is a perspective view of a fixing portion between the waterproof panel and the column, and FIG. 5 is a plan view thereof.

  The waterproof panel fence 1 includes a column 2 erected at a predetermined interval with respect to the foundation 31, a waterproof panel 9 fitted between the columns 2, and the column 2 on the outer surface of the waterproof panel 9. A side water-stopping rubber 29 provided therebetween and a panel fixing bracket 6 attached to the upper end of the column 2 are provided.

  The foundation 31 is made of, for example, concrete. As shown in FIG. 1, the foundation 31 is provided in a coastal area such as the sea (or river). The foundation 31 may be provided with a fitting hole (not shown) for fitting the column 2 to be erected, and the vicinity of the fitting hole (not shown) may be raised higher than the surroundings. Moreover, the foundation 31 may be an embankment installed in a coastal area.

In addition, the place where the foundation 31 is provided and the waterproof panel fence is installed is not limited to the coastal area, and a plurality of waterproof panel fences may be installed step by step toward the inland area in consideration of tsunami and flood overflow. included.

  The support column 2 is made of H-section steel in which a pair of support flange portions 4 and 5 are connected to both ends of the support column web portion 3. That is, the column 2 is formed with a groove portion surrounded by the column web portion 3 and the column flange portions 4 and 5. This support | pillar flange part 5 is arrange | positioned toward the land side, and the support | pillar flange part 4 is arrange | positioned toward the sea side (or river side). Further, an insertion hole 13 for attaching the panel fixing bracket 6 is provided at the upper end of the support web portion 3 in the support 2 as shown in FIG. As for the support | pillar 2, it is desirable to use a H-section steel from a viewpoint of manufacturing cost. However, the support column 2 is not limited to this, and any cross-sectional shape can be used as long as a groove portion is formed and the groove portion surrounds the vicinity of the end portion of the waterproof panel 9 and sufficient rigidity can be secured. You may be comprised with steel materials.

  FIG. 6 is a perspective view of the waterproof panel 9, and FIG. 7 is a side view thereof. As shown in FIGS. 6 and 7, the waterproof panel 9 includes a plurality of panel units 10 connected in series up and down, a waterproof sheet 26 interposed between adjacent panel units 10, and an adjacent panel unit 10. A connecting portion water stop rubber 27 is provided between the matching panel units 10 and attached to the end of the panel unit 10.

  The panel unit 10 includes a hollow square pipe 11 and reinforcing members 12 provided in the vicinity of both ends of the hollow part 25 provided inside the hollow square pipe 11.

  FIG. 8 is a perspective view of the panel unit 10, FIG. 9 (a) is a plan view thereof, and FIG. 9 (b) is a front view thereof.

  The hollow square pipe 11 is formed by an upper surface 21, side surfaces 23 and 24 orthogonal to both ends of the upper surface 21, and a lower surface 22 parallel to the upper surface 21 and orthogonal to the side surfaces 23 and 24. The hollow square pipe 11 is substantially rectangular in a plan view and substantially rectangular in a sectional view, but the corners of the four corners are curved. The hollow square pipe 11 is a metal steel material. Further, since the hollow square pipe 11 is hollow, it is made of metal and has high durability against external force due to water pressure, wave pressure, etc. while reducing the material cost compared to the case where it is configured in a solid state. Can be maintained. The hollow square pipe 11 may be of any shape, size and type as long as it is hollow and can ensure sufficient rigidity.

  As shown in FIG. 7, the hollow portion 25 has a substantially rectangular shape that is the same as the shape of the hollow square pipe 11 in a side view, and the corners of the four corners are preferably curved. However, the present invention is not limited to this, and any cross-sectional shape may be used as long as sufficient rigidity of the hollow square pipe 11 can be ensured.

  FIG. 9C is a cross-sectional view taken along the line bb ′ in FIG. However, FIG. 9C shows a case where the reinforcing member 12 is a substantially quadrangular reinforcing member 41 having a substantially quadrangular shape with a corner cut out. FIG. 10A is a cross-sectional view taken along the line bb ′ in FIG. 8 when the reinforcing member 12 is a reinforcing member 42 having a substantially octagonal shape. FIG. 10B is a cross-sectional view taken along line bb ′ in the case where the reinforcing member 12 is a substantially rectangular reinforcing member 43 that is separated from the upper surface 21 and the lower surface 22 of the hollow square pipe 11. FIG. 10C is a cross-sectional view taken along the line bb ′ when the reinforcing member 12 is a reinforcing member 44 that is a substantially square pipe (or a round pipe). FIG. 10D is a cross-sectional view taken along the line bb ′ when the reinforcing member 12 includes two reinforcing members 45 each including upper and lower steel bars and two reinforcing members 46 each including left and right steel bars.

  For example, the reinforcing member 12 is shown in FIG. 9C and FIGS. 10A to 10D, but is not limited to these shapes. The reinforcing member 12 is inscribed in at least one surface of the hollow rectangular pipe 11 in any shape. In particular, it is desirable that the reinforcing member 12 is fixed to at least the side surfaces 23 and 24 of the hollow square pipe 11 by welding or the like. Thereby, rigidity can be strengthened, even if water pressure or wave pressure is applied to the side surface 23 from the direction of the water pressure and wave pressure A in FIG. 1, and stress on the fixed portion of the column 2 and the waterproof panel 9 is concentrated. It is possible to prevent the waterproof panel 9 from being damaged. Further, it is desirable that the reinforcing member 12 is in contact with the upper surface 21 and the lower surface 22 of the hollow rectangular pipe 11 and is further fixed. Since the reinforcing member 12 and the upper surface 21 and the lower surface 22 are in contact with each other, the cross-sectional shape of the hollow rectangular pipe 11 can be prevented from being deformed into a parallelogram.

  The reinforcing member 12 has a gap 19 that communicates with the hollow portion 25 of the hollow square pipe 11. As shown in FIG. 9 (c) and FIGS. 10 (a) to (d), the presence of the gap 19 allows the hollow portion 25 to communicate with both ends of the hollow square pipe 11 for the rust prevention of the panel unit 10. This is because when plating or painting is performed, it is possible to easily inflow and discharge of the plating raw material and the paint into the interior. The plating material is, for example, zinc. However, the present invention is not limited to this, and other plating such as copper may be used. From the viewpoint of rust prevention of the panel unit 10, it is not limited to plating, and may be paint. Further, in any of the shapes shown in FIG. 9C and FIGS. 10A to 10D including the gap 19, the vicinity of the corner of the reinforcing member 12 is notched, so that a hollow square pipe is obtained. It is desirable to be separated from the inside of the 11 corners. Thereby, it is not necessary to manufacture the reinforcing member 12 having the outer periphery of the same shape in order to be inscribed with the inner periphery of the hollow rectangular pipe 11, and it is not necessary to match the shapes of the hollow rectangular pipe 11 and the reinforcing member 12. . Therefore, it becomes easy to attach the reinforcing member 12 to the inner surface of the hollow square pipe 11.

  The vertical width of the substantially rectangular reinforcing member 43 shown in FIG. 10B needs to be a certain length. This is because, when the force is received from the direction of the water pressure and the wave pressure A shown in FIGS. 4 and 5, if the vertical width is short, the force may not be properly transmitted from the side surface 23 to the side surface 24. . For the same reason, also in the two steel bar reinforcing members 46 provided on the left and right shown in FIG. 10 (d), the upper and lower widths need to have a certain length. The reinforcing member 12 is not limited to a material made of steel, and may be made of concrete or a composite material of steel and concrete.

  Further, as shown in FIGS. 6 and 7, the adjacent panel units 10 are connected to the insertion holes 14 in the vicinity of the ends of the lower surface 22 of the upper panel unit 10 and the upper surface 21 of the lower panel unit 10. The connecting bolt 15 may be inserted through the upper surface 21 of the panel unit 10 on the lower side and may be screwed and fixed by the connecting nut 16 on the lower surface 22 of the panel unit 10 on the upper side. Alternatively, the present invention is not limited to this. For example, as long as sufficient rigidity and waterproofness of the panel unit 10 can be secured, the side surfaces 23 and 24 of the panel units 10 adjacent to each other may be fixed by welding or the like. Good.

  The waterproof sheet 26 is interposed between the lower surface 22 of the panel unit 10 on the upper side and the upper surface 21 of the panel unit 10 on the lower side in the panel units 10 adjacent to each other vertically. Further, as shown in FIG. 6, the waterproof sheet 26 has a substantially rectangular shape in plan view, and the width of the waterproof sheet 26 in the short direction is the same as the upper surface 21 and the lower surface 22. It may be smaller, and is interposed from one end to the other end in the entire longitudinal direction of the panel unit 10. Moreover, the raw material of the water stop sheet | seat 26 is comprised by elastic bodies, such as rubber | gum, for example. The presence of the water blocking sheet 26 can prevent water from entering the land side against the tsunami and flooding from the water pressure, wave pressure A direction in FIG. Note that the shape, size, and material are not limited to this, and the sheet may be formed of any shape, size, and material as long as sufficient water stoppage can be secured. In addition, since the water stop sheet | seat 26 is interposed to the both ends of the longitudinal direction of the panel unit 10, the connection bolt 15 penetrates the water stop sheet | seat 26 at the time of the connection of the above-mentioned connection bolt 15, and it adjoins mutually. The upper and lower panel units 10 are fastened. Thereby, the panel units 10 adjacent to each other can be connected in a state where the water-stop sheet 26 is elastically deformed, and a high water-stop effect is produced.

  As shown in FIGS. 6 and 7, the connecting portion water blocking rubber 27 is attached to the end of the panel unit 10, and in the panel units 10 adjacent to each other, the lower surface 22 of the upper panel unit 10 and the lower panel unit. 10 is attached so as to fill a gap between the upper surfaces 21 of the ten. This gap is generated when the corner portion of the substantially rectangular shape in the panel unit 10 is curved in a sectional view. In particular, in the gap D at the end of the panel unit 10, a caulking material 28 such as silicone, modified silicone, or polyurethane may be used in place of the connecting portion waterstop rubber 27.

  The side waterstop rubber 29 may be fitted or fixed in the panel unit 10 with almost no gap between the column flange portions 4 and 5 of the column 2. Alternatively, the side water blocking rubber 29 may be arranged so as to provide a gap such as a gap B between the panel unit 10 and the column flange portions 4 and 5 as shown in FIGS. . Since the side waterstop rubber 29 also serves as a fulcrum for supporting the vicinity of the end of the panel unit 10 and the column flange portions 4 and 5, the side waterstop rubber 29 is made of relatively hard rubber. The side water blocking rubber 29 can prevent water from entering from the gap B formed between the waterproof panel 9 and the support column 2 shown in FIG. Furthermore, in order to enhance the water stop effect, by attaching the above-mentioned connecting portion water stop rubber 27, it is possible to prevent water from entering the gap C shown in FIG. That is, the entire gap between the lower surface 22 of the upper panel unit 10 and the upper surface 21 of the lower panel unit 10 is formed by the side surface waterproof rubber 29 and the connecting portion water stop rubber 27 in the vicinity of the ends of the adjacent panel units 10. Can be filled. The side water blocking rubber 29 may be provided at the same position outside the side surfaces 23 and 24 in correspondence with the position of the reinforcing member 12 in contact with the side surfaces 23 and 24 of the panel unit 10.

  As shown in FIGS. 4 and 5, the panel fixing bracket 6 is provided for pressing and fixing the panel unit 10 fitted between the columns 2 from above. The panel fixing bracket 6 includes a contact plate 61 that contacts the support web portion 3 of the support 2, and a pressing plate 62 and a stiffening plate 63 that are orthogonal to the contact plate 61. The contact plate 61 has an insertion hole (not shown) through which the bolt 7 is inserted. The tip of the bolt 7 is further inserted through an insertion hole 13 provided in the support web portion 3 and is screwed and fixed by a nut 8 from the opposite side of the support web portion 3. The holding plate 62 is angle-adjusted so that it forms a horizontal plane when fixed, and the stiffening plate 63 forms a vertical plane when fixed. Then, the bottom surface of the pressing plate 62 is fixed so as to press the upper surface 21 of the panel unit 10. Thereby, when water overflows due to unexpected flooding or tsunami height, it is possible to suppress the panel unit 10 from going up due to buoyancy via the pressing plate 62. The shape of the panel fixing bracket 6 is not limited to the above-described configuration. At least the contact plate 61 that can contact the support web portion 3 of the support 2 and the panel unit 10 can be pressed from above. Any shape may be used as long as it has a possible holding plate 62.

  Next, in the waterproof panel and the waterproof panel fence to which the present invention is applied, how to receive the stress when water pressure or wave pressure such as flood or tsunami is applied, and how to attach the waterproof panel to the column while referring to the drawings This will be described in detail.

  As shown in FIGS. 4 and 5, the reinforcing member 12 is provided corresponding to the position where the side water blocking rubber 29 in the gap B between the waterproof panel 9 and the column 2 is in contact with the outer surface of the hollow square pipe 11. It has been. Thereby, the force received on the side surface of the panel unit 10 is transmitted to the side water blocking rubber 29 and the support column 2 through the reinforcing member 12.

  The method of assembling the waterproof panel 9 and the support column 2 is not shown in the eyebolt insertion holes 17 shown in FIGS. 1 and 2 provided near both ends of the upper surface 21 of the uppermost panel unit 10 of the waterproof panel 9, for example. It can be assembled by inserting an eyebolt and screwing and fixing the eyebolt from the lower side of the upper surface 21 with an eyebolt nut 18 and hanging the eyebolt on a wire with a crane or the like. In that case, you may assemble to the support | pillar 2 by making the whole waterproof panel 9 into one panel. Alternatively, two or more panel units 10 are combined to form a small panel, and eyebolts are inserted into eyebolt insertion holes 17 provided in the uppermost panel unit 10 and suspended by a crane or the like, and divided into several times. May be assembled to the support column 2. In any case, since each panel unit 10 is connected to the top and bottom, it can be installed on the support column once or several times compared to the case where the panel unit 10 is fixed to the support column one by one. Are better. Moreover, since each panel unit 10 is connected, the favorable water stop effect can be anticipated.
