The present invention relates to an assembly pool formed by connecting with nuts. 2. Description of the Related Art Conventionally, a joint flange is integrally formed on each of a plurality of pool segments formed of plastic, a waterproof strip is interposed between adjacent joint flanges, and the joint flanges are connected by bolts and nuts. The assembled pool is being implemented. Further, the conventional pool segment is formed in a shape obtained by dividing the water tank body in parallel only in the vertical direction. [0004] In the conventional example, the pool segment itself is large because the pool segment is divided only in the vertical direction, and a large area is required when the assembled pool is disassembled for transportation or storage. In particular, it is difficult to secure a storage place in an urban area, and the assembly pool having the above structure is difficult to use. For this reason, if the water tank body is divided so as to intersect in a plurality of directions, the pool segment can be downsized. In this case, however, a waterproof strip is provided between the divided edges of each pool segment as in the conventional example. If the bolts and nuts are only tightened with water, water will leak at the position where the divided edges intersect, and it is extremely difficult to make the liquid at the intersecting position. As a result, it is not possible to implement an assembled pool composed of pool segments in which the water tank body is divided so as to intersect in a plurality of directions. The present invention is to solve the above-mentioned problems, that is, a joint flange is integrally formed on each of a plurality of pool segments formed of plastic, and the joint flanges are formed between adjacent joint flanges. In an assembled pool in which a waterproof strip is interposed and the joining flange is connected by a bolt and a nut, the plurality of pool segments are formed in a shape in which the water tank body is divided so as to intersect in a plurality of directions. Is formed on the divided edge of each pool segment, a concave portion having a wall surface is formed at the intersection of the divided edge, and a concave portion is formed by the assembly of the plural concave portions associated with the connection of the plural pool segments. An elastic plug is removably provided in the concave portion, and the elastic plug has a plug expansion / contraction that vertically penetrates the elastic plug. A male screw is provided, and the elastic plug is brought into close contact with the wall surface by tightening the male screw and the female screw. The shape of the aquarium body divided so as to intersect in a plurality of directions is, for example, a shape in which the aquarium body is vertically and horizontally divided, a shape in which the aquarium body is radially divided, or a shape in which the aquarium body is vertically and horizontally and radially divided. Alternatively, when the water tank body is formed in a vertically and horizontally divided shape, the intersecting positions of the dividing edges are orthogonal to the dividing edges. [Action] A plurality of pool segments are brought close to each other, a waterproof strip is interposed between the divided edges of the adjacent pool segments, and bolts and nuts are tightened to connect the adjacent connection base flanges.
Next, an elastic plug is inserted into a recess formed by a set of a plurality of recesses, and the screw is tightened with a screw for expanding and contracting the plug. Here, the elastic plug contracts in its longitudinal direction, and a force acts to swell in the centrifugal direction, so that the more the screw is tightened, the more the elastic plug is fitted into the recess.
