Description

  The present invention relates to an assembly pool made of plastic used in a facility for children such as a kindergarten and a nursery school.

Conventionally, a relatively large plastic assembly pool having a length of 210 cm, a height of 58 cm, and a width of 210 cm to 420 cm or more is used in the facility.

  Because of the size, each segment is formed of high strength FRP.

Utility Model No. 63-28790 Utility Model Gazette

None.

  In the conventional example, a plurality of segments are connected, and as described above, the segments are long and made of FRP, so the weight is large, so that assembly, transportation and storage are not easy, and recycling is not easy. It is not an exaggeration to say that it is possible, and FRP itself is a single layer, and due to the fiber used as the core material, it must be thick, hard, and the swimmer has a large impact on the peripheral wall. If added, the swimmer may not be injured. Furthermore, much labor and time are required for production, such as lamination and sticking peculiar to FRP.

  In the conventional example, the steps necessary for entering and exiting the pool need to be manufactured as a separate part and retrofitted as in the above-mentioned patent document.

  This invention makes it a subject to eliminate the said fault, after raising intensity | strength.

  According to a first means of the present invention, in an assembly pool in which a plurality of plastic segments are connected by bolts and nuts, each segment is formed by connecting a pair of cells having the same shape and having a peripheral wall and a bottom. Forming a double structure having a hollow portion by blow molding polyethylene resin, and forming a first reinforcing means formed by partially integrating the peripheral wall of the hollow portion, and a floor plate and a ground plate at the bottom having the hollow portion A plurality of second reinforcing means for partially connecting the two are formed.

  According to a second means of the present invention, in the first means, the cell is four corner cells.

  According to a third means of the present invention, in the second means, the corner cell has an integral inner step and outer step.

  According to a fourth means of the present invention, in the first means, the segment is composed of one or a plurality of segments composed of four corner cells and a pair of intermediate cells, and each corner cell and each of the intermediate cells are arranged vertically. The horizontal and height dimensions are the same.

  According to a fifth means of the present invention, in the first means, an engaging step is formed on the upper surface of the opposing end of each cell, a concave portion is formed on the opposing outer surface, and a bolt insertion hole is formed in the concave portion and the opposing inner surface. The bush portion of the outward flanged bush is inserted into a hollow portion formed by the opposed inner surface and the opposed outer surface, the collar portion is locked to the recess, the collarless end is in contact with the opposed inner surface, and the bolt is It penetrates the inside of the insertion hole and the bush with outward flange, and is fastened with a nut.

  A sixth means of the present invention is characterized in that, in the fifth means, a recessed portion for tightening a bolt and a nut is formed for each bolt and nut, and a waterproof cap is removably provided in the recessed portion. To do.

  According to a seventh means of the present invention, in the second, third, or fourth means, each corner cell is provided with a drain hole, and the first plug is detachably provided in the drain hole and a hose attaching / detaching means is provided. It is a feature.

  According to an eighth means of the present invention, in the second, third, fourth, or seventh means, a bottomed recessed hole is formed in each corner cell, the hole is drilled as desired, and the second plug is detachably attached to the drilled hole. Is provided.

  The present invention has a double structure having a hollow portion made of polyethylene resin and has first and second reinforcing means, has good water resistance, high strength, low weight, assembly and transportation.・ Easy storage, and one segment is formed of a pair of cells of the same shape, making it even more compact in the disassembled state, easier to transport and store, and a pool that combines only corner cells When manufacturing, one type of mold, and when manufacturing pools combining corner cells and intermediate cells, two types of molds are sufficient, and they can be manufactured very easily and quickly compared to FRP. In addition, it can be easily crushed and recycled, and despite its high strength, its hardness is lower than that of FRP. Also participating is possible avoidance by elasticity, there is no risk of injury.

  Further, since the present invention integrally forms the inner step and the outer step in the corner cell, it is not necessary to separately form and retrofit these steps.

  Furthermore, the present invention has a double structure having a hollow portion, but in the bolt and nut fastening portion, a bush is inserted into the hollow portion of each opposing end, and the outward flange portion of the bush is locked to the concave portion, and the end portion without the flange Since each of the opposing ends having the hollow portion is not deformed, the cells can be reliably connected even if the bolts and nuts are tightened firmly.

  Further, since each corner cell is provided with a drain hole, a first stopper and a hose attaching / detaching means, a drain hose can be attached at a desired position, and a bottomed recessed hole is formed at each corner cell. It is possible to remove the mud if the bottomed concave hole is easily drilled and plugged and then opened after using the pool, and it is not necessary to drill the unnecessary part.
