The bottom 10 refers to a part that plugs the bottom of the cage block 2 in a state where liquid can flow in, and has a plurality of through holes 10a for liquid to flow in. In addition, in the center of the bottom portion 10, a connection portion that connects the bottom portions 10 up and down is formed when the accumulation unit 1 is stacked.

Here, as shown in FIGS. 2 to 4, when the structure 4 constituting the accumulation unit 1 is composed of two cage-shaped blocks 2, One cage block 2 is provided with a convex portion 10e protruding from the bottom 10 toward the outer side of the cage block 2 as a connecting portion; the other cage block 2 is provided with a bottom 10 embedded in the cage block 2 The inner concave portion 10f serves as a connecting portion. Furthermore, the connecting portion is supported by a plurality of rib materials so as to be located at the center of the bottom 10.

Fig. 5 is a plan view showing the reinforcing frame constituting the accumulation unit 1 of the embodiment, and Fig. 6 is a perspective view of the reinforcing frame viewed from above. As shown in FIGS. 5 and 6, the reinforcing frame 6 has a structure in which four square frame portions 6a are connected, and is formed by injection molding polypropylene. Here, each frame portion 6a has a shape corresponding to the flange portion 12. In addition, the four frame portions 6a are formed in a square frame shape by connecting two of the four sides constituting the frame portion 6a with two sides of the other frame portion 6a, and forming a cross-shaped rib in the center.

In addition, on the front and back surfaces of the reinforcing frame 6, concave portions 6b for accommodating the protrusions 12a (refer to Figs. 2 and 4) are provided at predetermined intervals so as to surround the respective frame portions 6a.

Next, taking the case of constructing a rainwater storage tank by stacking even-numbered layers of structures 4 as an example, the procedure for constructing a rainwater storage tank using the storage unit 1 of the embodiment will be described. Furthermore, in the following description, because it is only The content of the description is focused on the construction of the rainwater storage tank, so the arrangement sequence of the attached parts such as the laying of the bottom protection sheet or the connection of the water supply pipe is omitted.

First, as shown in FIG. 7(a), the worker places the cage-shaped block 2 on the bottom surface of the excavated foundation so that the opening 8 is on the upper side. Here, the cage-shaped block 2 which has the convex part 10e in the bottom part 10 among the cage-shaped block 2 located in the lowermost layer is placed after cutting the convex part 10e. Thereby, the heights of the bottom 10 and the flange 12 of the cage block 2 located at the lowermost layer can be made uniform.

Next, the operator makes the position of the recessed portion 6b (see Figures 5 and 6) formed on the reinforcement frame 6 and the protrusion 12a formed on the flange portion 12 of the cage block 2 (see the second Figure, Figure 4) are in the same position, and the reinforcing frame 6 is placed on the cage block 2 above. Thereby, the protrusion 12 can be fitted into the concave portion 6 and the reinforcing frame 6 can be fixed to the structure 4.

Next, as shown in FIG. 7(b), the worker system further covers the cage-shaped block 2 above the reinforcing frame 6 so that the opening 8 becomes the lower side. Here, in the case of covering the cage block 2, for example, as shown in Fig. 8, the operator straddles the two reinforcing frames 6 to cover the structure 4, thereby connecting the plurality of reinforcing frames 6 to the horizontal direction.

Next, as shown in Fig. 7(c), the operator is attached to the upper side of the cage block 2 with the opening 8 as the lower side and placed on the reinforcing frame 6, and further places the opening 8 as the upper side. State of the cage block 2. In this case, the operator attaches the cage block 2 where the convex portion 10e has been formed on the bottom 10 and overlaps the cage block 2 where the concave portion 10f has been formed on the bottom 10, and the concave portion 10f has been formed on the bottom 10 The upper part of the cage block 2 The overlapping convex portion 10e has been formed on the cage block 2 of the bottom 10. Thereby, the convex part 11e can be fitted into the recessed part 10f, and the cage-shaped block body 2 which forms the direction of the opening part 8 in the opposite direction can be mounted up and down so that it may not shift in a horizontal direction.

Hereinafter, as shown in Fig. 9, by repeating the same operation, a rainwater storage tank composed of a plurality of layers of cage-shaped blocks 2 can be constructed. In addition, the cage-shaped block body 2 which has the convex part 10e in the bottom part 10 among the cage-shaped block body 2 located in the uppermost layer may be placed after cutting the convex part 10e. Thereby, the heights of the bottom 10 and the flange 12 of the cage block 2 located at the uppermost layer can be made uniform.

According to the invention of this embodiment, by covering the cage block 2 across the two reinforcing frames 6 to connect the accumulation units 1 horizontally, a plurality of accumulation units 1 can be firmly connected to each other. Moreover, instead of using a conventional joint member, a reinforcing frame 6 is used to connect a plurality of structures 4, whereby the storage units 1 can be connected to each other with a simple structure. Therefore, the horizontal tolerance of the accumulation unit 1 can be enhanced. In addition, since the joint member is not used, the number of parts constituting the rainwater storage tank can be reduced, and the rainwater storage tank can be constructed at low cost.

In addition, since the reinforcing frame 6 has a structure in which four square-shaped frame portions 6a are connected, and the structure 4 is composed of two cage-shaped blocks 2, even if the structure is covered by spanning the two reinforcing frames 6 The structure 4 connects the reinforcing frames 6 to each other, and there is no excess or deficiency in the structure 4. For example, as shown in Figure 10 (a) and (b), the direction of the structures 4 arranged at both ends of the rainwater storage tank is orthogonal to the direction of the other structures 4 The configuration can be configured to match the shape of the reinforcing frame 6 物4.

Furthermore, according to the invention of this embodiment, since the storage unit 1 can be easily connected without using a joint member, the storage unit 1 can be connected with a complicated shape, for example, as shown in FIG. 11.

Furthermore, in the above-mentioned embodiment, although the case of stacking even-numbered layers of structures 4 to construct a rainwater storage tank has been described as an example, it is also possible to stack odd-numbered layers of structures 4 to construct a rainwater storage tank. In this case, first, as shown in Figure 12(a), the operator places the reinforcement frame 6 on the bottom surface of the excavated foundation, and above the reinforcement frame 6, the opening 8 becomes the lower side Way to cover the cage block 2.

Hereinafter, as in the case of stacking even-numbered layers of structures 4, the reinforcement frame 6 and the structures 4 are alternately stacked, and as shown in FIG. 12(b), a rainwater storage tank with a predetermined layer thickness is completed.

However, according to the present invention, since the reinforcing frame 6 replaces the joint member to withstand the horizontal earth pressure, as shown in Figure 12(a), it is also possible to construct a rainwater storage composed of a storage unit 1 composed of only one layer groove. Therefore, even if the underground depth is relatively shallow, the rainwater storage tank can be buried. Furthermore, since the storage unit 1 can be constructed using the reinforcing frame 6 with strong horizontal resistance, even if the bottom surface of the excavated foundation is deepened, the rainwater storage tank can be buried. Therefore, by appropriately stacking the structures 4 into even-numbered or odd-numbered layers, rainwater storage tanks that meet various depths can be constructed.

In addition, in the above-mentioned embodiment, the cage-like block 2 included in one structure 4 may be provided with the same kind of connection part. That is, the following structure 4 may also be provided: as shown in Figure 13(a), only a cage provided with a convex portion 10e The structure 4 of the shaped block 2; and the structure 4 having only the cage-shaped block 2 provided with the recess 10f as shown in FIG. 13(b). Even in this case, it is possible to overlap the concave portion 10f over the cage block 2 where the convex portion 10e is formed on the bottom 10 in the same order as that described using FIGS. 7-9. The cage block 2 formed on the bottom 10 or the cage block 2 with the convex portion 10e formed on the bottom 10 overlaps the cage block 2 with the concave portion 10f formed on the bottom 10 while constructing a rainwater storage tank .

Furthermore, in the case where only the structure 4 having the cage block 2 provided with the concave portion 10f is used in the lowermost layer or the uppermost layer, the lowermost layer or the uppermost layer can be easily made without cutting the convex portion 10e. The bottom 10 and flange 12 of the structure 4 have the same height.

In this way, even when the structure 4 having only the cage block 2 with the convex portion 10e and the structure 4 having only the cage block 2 with the concave portion 10f are used to construct the rainwater storage tank, it is still possible By fitting the convex portion 10e into the concave portion 10f, the cage-shaped blocks 2 are loaded up and down so as not to be displaced in the horizontal direction.

In addition, in the above-mentioned embodiment, the structure 4 and the reinforcing frame 6 are not limited to polypropylene, and may be formed of other thermoplastic resins. In addition, the structure 4 or the reinforcing frame 6 may be produced by a method other than injection molding.

In addition, in the above-mentioned embodiment, the structure 4 may not necessarily be composed of two cage-shaped blocks 2. For example, it may have an L-shaped solid state composed of three cage-shaped blocks 2. In addition, it may be composed of four cage-shaped blocks 2, and each cage-shaped block 2 corresponds to each frame portion 6a constituting the reinforcing frame 6.

In addition, in the above-mentioned embodiment, although it has been described that the rainwater storage tank can be constructed without using the joint member, it is also possible to construct the rainwater storage tank using the joint member. In addition to the reinforcing frame 6, a joint member is further used to construct a stronger rainwater storage tank.

Moreover, in the above-mentioned embodiment, as shown in FIG. 14, when constructing a rainwater storage tank, you may attach the top plate 14 to the structure 4 which comprises the uppermost layer of a rainwater storage tank. Here, the top plate 14 refers to a member having two openings 14a that is substantially rectangular in plan view, and the openings 14a have the same size as the bottom 10 of the cage block 2. After cutting the convex portion 10e, the top plate 14 is attached to the structure 4 constituting the uppermost layer of the rainwater storage tank so that the bottom 10 is nested in the opening, as shown in Figure 15, so that the rainwater can be removed. The upper surface of the water storage tank is formed in a flat shape.

Moreover, in the above-mentioned embodiment, the reinforcement frame 6 may have a shape combining thin-walled members. That is, the reinforcement frame 6 may be formed with a plurality of concave portions surrounded by the thin-walled side walls and the thin-walled bottom surface, and the concave portion may be formed to appropriately reinforce the resistance of the reinforcement frame 6 rib.

Thereby, the reinforcing frame 6 can be formed as a light-weight and high-strength member, and especially the horizontal resistance can be strengthened. In addition, in this case, the concave portion 6b may use a concave portion located at a position corresponding to the position of the protrusion 12a when the flange portion 12 is superimposed on the reinforcing frame 6.

Similarly, the flange portion 12 may also have a shape combining thin-walled members. That is, the flange portion 12 may be formed with a thin There are a plurality of concave portions surrounded by the side walls of the wall and the bottom surface of the thin wall, and ribs are formed in the concave portions to appropriately strengthen the resistance of the flange portion 12.

Moreover, in the above-mentioned embodiment, although the case where the cross-sectional shape of the recessed part 6b formed in the reinforcement frame 6 is rectangular was demonstrated as an example, the cross-sectional shape of the recessed part 6b may be circular.
