  An object of the present invention is to provide a structure capable of remarkably increasing the capacity used for storing and infiltrating rainwater and the like, and a storage and infiltration facility for rainwater and the like.

  In order to solve the above-described problem, the structure according to the present invention includes a plurality of partition members, a plurality of side plate members, and a plurality of face plate members. Each of the partition members has a flat shape, has two sides facing each other in the width direction, and is arranged at a distance from each other.

  The side plate member has a flat shape and is coupled to the two sides of the partition member. Each of the face plate members has a concave portion on one side of the two opposite sides, and has a convex portion corresponding to the concave portion on the other side. It is integrated as a whole by concave-convex fitting into which the part is fitted. In the partition plate and the side plate member, the sides in the height direction are unevenly fitted between two protrusions provided on one surface of the face plate member between adjacent face plate members.

  The structure according to the present invention is combined with a water-permeable layer or a water-impervious layer, and constitutes a storage and infiltration facility such as rainwater. In storage and penetration facilities such as rainwater, the structure is buried in the ground. The water permeable layer or the water shielding layer is provided around the structure. When a permeable layer is used, a rainwater penetration facility is configured, and when a water shielding layer is used, a rainwater storage facility is configured.

  In this case, each of the partition members has a flat shape and is spaced from each other, and a flat side plate member is coupled to two sides in the width direction. Accordingly, the number of partition members corresponding to the length of the side plate members can be arranged at intervals, and the capacity used for storing and penetrating rainwater or the like can be remarkably increased.

  Moreover, the structure according to the present invention includes a plurality of face plate members, and each of the face plate members has a concave portion on one side of the two opposite sides, and a convex portion corresponding to the concave portion on the other side. The adjacent face plate members are integrated as a whole by concave / convex fitting into which the other convex portion is fitted into one concave portion. The partition plate is unevenly fitted between two projections provided on one surface of the face plate member between adjacent face plate members in the height direction. Therefore, a structure with high mechanical assembly strength can be obtained by the concave-convex fitting structure between the face plate member and the partition plate while being easily assembled.

  Furthermore, the partition member, the side plate member, and the face plate member are all flat. Therefore, since these can be transported in a mode that is not bulky, the transportation cost can be reduced. Moreover, since it is lightweight, the assembly work to a structure can be performed easily.

  Other objects, configurations and advantages of the present invention will be described in more detail with reference to the accompanying drawings. The drawings are merely examples.

  As described above, according to the present invention, it is possible to provide a structure that allows a worker to enter the inside and perform maintenance management such as sediment removal, and a storage and penetration facility for rainwater and the like.

  FIG. 1 is a perspective view of a structure according to the present invention. The illustrated structure includes side plate members (3A, 3B), (3C, 3D), a plurality of partition members 4, and a plurality of face plate members 1. These can be configured as a molded product using an appropriate plastic material or a composite material in which a plastic material and an inorganic powder are mixed.

  The partition member 4 is flat and has two sides that face each other in the width direction. The through hole 41 penetrates from one surface to the other surface. A plurality of partition members 4 are arranged at intervals in the length direction. The side plate members (3A, 3B), (3C, 3D) have a flat shape and are coupled to two opposite sides of the partition member 4 in the width direction.

  As described above, each of the partition members 4 is flat and spaced from each other, and flat side plate members (3A, 3B), (3C, 3D) is bound. Accordingly, the number of partition members 4 corresponding to the lengths of the side plate members (3A, 3B) and (3C, 3D) can be arranged at an interval to significantly increase the capacity for storage and infiltration of rainwater and the like. .

  As shown in an enlarged view in FIG. 2, the face plate member 1 has an approximately regular square shape as a whole, and is provided with a concave portion 13 at a substantially middle portion between two adjacent sides, and is projected at a middle portion between the other two adjacent sides. A portion 14 is provided. Convex portions 14 are provided on both sides of the concave portion 13, and concave portions 13 are provided on both sides of the convex portion 14. The concave portion 13 and the convex portion 14 have a shape that can constitute a so-called “Hatoo joint”. Therefore, in the adjacent face plate members 1, 1, a flat bottom plate arrangement structure that is integrated as a whole can be realized by concave / convex fitting in which the other convex portion 14 is fitted into one concave portion 13.

  Unlike the embodiment, the face plate member 1 may have another square shape, for example, a hexagonal shape, an octagonal shape, or the like. The formation positions of the concave portions and the convex portions are selected according to the outer shape of the face plate member 1.

  A pair of protrusions 15 and 16 are provided along one side on one or both surfaces of the face plate member 1. FIG. 3 is an enlarged partial sectional view showing the portions of the protrusions 15 and 16. In the illustrated embodiment, two protrusions 15 and 16 are provided on the convex portion 14 at opposite positions on both surfaces of the face plate member 1 with a gap therebetween.

  FIG. 4 is a partially enlarged cross-sectional view showing another example of the protrusions 15 and 16. In this embodiment, the two protrusions 15 and 16 have inward hook portions at their upper ends.

  In order to configure the structure of the illustrated embodiment, the face plate member 1 is used as a bottom plate, the partition member 4 and the side plate members (3A, 3B), (3C, 3D) are coupled to each other by concave and convex fitting. In addition, another face plate member 1 need only be concavo-convexly fitted as a top plate. For this reason, the assembling work becomes extremely easy.

  Moreover, in the face plate member 1, one side of the two opposite sides has a recess 13, and the other side has a projection 14 corresponding to the recess 13. Therefore, in the adjacent face plate members 1, 1, it is possible to realize a flat bottom plate arrangement structure that is integrated as a whole by concave / convex fitting into which the other convex portion 14 is fitted into one concave portion 13. In this way, the face plate member 1 serving as the bottom plate is laid by uneven fitting, so that the assembling work becomes extremely easy. The face plate members 1 are arranged in a necessary number according to the length required for the structure, and are connected to each other by concave and convex fitting.

  On one side of the face plate member 1, side plates (3A, 3B), (3C, 3D) and one side of the partition plate 4 are joined by concavo-convex fitting. Concave / concave fitting is performed by inserting one side of the side plate members (3A, 3B), (3C, 3D) and the partition plate 4 between the two protrusions 15, 16 provided on one surface of the face plate member 1. Is done. As described above, since the coupling of the face plate member 1, the side plate members (3A, 3B), (3C, 3D) and the partition plate 4 is also due to the concave / convex fitting, the assembling work becomes extremely easy.

  In the embodiment, the side plate members (3A, 3B), (3C, 3D) and the partition plate 4 are shared by the adjacent face plate members 1. Therefore, cost reduction, easy assembly, and quick assembly can be achieved.

  On the side plate members (3A, 3B), (3C, 3D) and the partition plate 4, a face plate member 1 (not shown) serving as a top plate is coupled by concave-convex fitting. For this reason, the assembling work of the face plate member 1 with respect to the side plate members (3A, 3B), (3C, 3D) becomes extremely easy.

  In addition, in the face plate member 1, one of the two opposite sides has a recess 13 and the other side has a projection 14 corresponding to the recess 13, so that the other recess 13 in one face plate member 1 The convex plate 14 of the face plate member 1 is fitted and integrated as a whole by fitting the concave and convex portions, and a flattened top plate arrangement structure can be realized. For this reason, the assembling work becomes extremely easy.

  Furthermore, the partition member 4, the side plate members (3A, 3B), (3C, 3D), and the face plate member 1 are all flat. Therefore, since these can be transported in a mode that is not bulky, the transportation cost can be reduced. Moreover, since it is lightweight, the assembly work to a structure can be performed easily.

  FIG. 5 is a perspective view showing an assembly structure of the side plate members (3A, 3B), (3C, 3D) and the partition member 4, and FIG. 6 is an exploded perspective view of the assembly structure shown in FIG. As illustrated, the two side plate members (3A, 3B) and (3C, 3D) are coupled to two sides in the width direction of the partition member 4. The coupling means is preferably a mechanical coupling means, in particular, concave-convex fitting, from the viewpoint of ease of assembly and mechanical coupling strength.

  The partition member 4 has an outer frame portion 42, and has a through hole 41 in a plane surrounded by the outer frame portion 42. Moreover, it has the several rib 45 extended radially from the ring part 44 which comprises the through-hole 41 toward the outer side. The through hole 41 has a size that allows a human to dive through. The side plate members (3A, 3B) and (3C, 3D) are also flat and have a through hole 31 penetrating from one surface to the other surface.

  In the illustrated embodiment, the side plate members (3A, 3B) and (3C, 3D) include two types. The first side plate member 3A and the second side plate member 3C belong to the first type, and the first side plate member 3B and the second side plate member 3D belong to the second type.

  In the first side plate member 3 </ b> A and the second side plate member 3 </ b> C belonging to the first type, the through hole 31 has a size that allows a human to dive through. The through holes 31 of the second side plate member 3B and the second side plate member 3D of the second type are not intended for humans to dive through, but are used as insertion ports for cleaning hoses.

  The length, width, and height of the structure can be arbitrarily changed by selecting the number of face plate members 1 to be laid. Therefore, in a practical situation, a structure having a required length, width and height can be easily realized. Furthermore, the number of stages can be increased to increase the volume.

  For example, as shown in FIG. 7, it is possible to employ a structure in which face plates are arranged after a plurality of the structures shown in FIGS. 5 and 6 are directly stacked.

  The structure described above is used to construct a storage and penetration facility for rainwater and the like. 8 and 9 are diagrams schematically showing a configuration of a rainwater infiltration facility in which the structure F according to the present invention is embedded in the ground. The structure F according to the present invention is buried in the ground, and the upper side is covered with a layer 8 such as soil, gravel, concrete or asphalt. The periphery of the structure F is covered with a protective layer 6 such as a non-woven fabric according to a well-known technique to prevent the inflow of earth and sand into the structure F.

  The inflow pipe 5 is inserted into the structure F. The inflow pipe 5 is inserted into the partition member 4 included in the structure F. One end of the inflow pipe 5 is connected to the water collecting tank 7. Accordingly, the rainwater collected in the water collecting trough 7 flows into the structure F from one end of the inflow pipe 5. Rainwater that flows into the structure F from the inflow pipe 5 penetrates into the ground.

The structure F includes an assembly constituted by the face plate member 1, the side plate members (3A, 3B), (3C, 3D) and the face plate member 1, and the internal space volume becomes extremely large. For this reason, compared with the case where the crushed stone is spread, a structure having a very high space ratio and a high capability of rainwater storage and rainwater infiltration is obtained. Moreover, the partition member 4, the first side plate member, and the second The side plate members include through holes 31 and 41, respectively. The through hole 41 penetrates from one surface to the other surface. Therefore, by designing the hole diameters of the through holes 31, 41 provided in the partition member 4 and the side plate members (3A, 3B), (3C, 3D) to a size that allows an operator to pass, A member can enter the inside of the storage and penetration facility such as rainwater through the through holes 31 and 41, and can remove deposits such as dust accumulated therein.

  Moreover, the partition member 4 and the side plate members (3A, 3B), (3C, 3D) included in the structure F are each flat. Therefore, since the partition member 4 and the side plate members (3A, 3B) and (3C, 3D) can be transported in a manner that is not bulky, the transportation cost can be reduced. Moreover, since the partition member 4 and the side plate members (3A, 3B), (3C, 3D) are lightweight, they are easy to handle when assembling the structure F, and the assembly work can be easily performed.
