Description

本発明は幼稚園、保育園等の子供用施設で用いられるプラスチック製の組立プールに関する。   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.

従来から前記施設では、例えば縦210cm、高さ58cm、横210cm〜420cm以上の比較的大きいプラスチック製の組立プールが使用されている。 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.

前記大きさなので、各セグメントを強度の高いFRPで形成している。   Because of the size, each segment is formed of high strength FRP.

実公昭63−28790号実用新案公報Utility Model No. 63-28790 Utility Model Gazette

なし。None.

従来例は複数のセグメントを接続するものであり、既述のとおりセグメントの縦寸法が長く、しかもFRP製であるので、重量が大きく、このため組立、運搬、保管が容易ではなく、リサイクルも不可能といっても過言ではなく、またFRPはそれ自体が単層であり、芯材とする繊維の関係上、肉厚にならざるを得ず、硬度が高く、遊泳者が周壁に大きい衝撃を加えた場合、逆に遊泳者が負傷するおそれがないとは限らない。さらにFRP特有の積層・貼り付け等、製造に多くの労力と時間を必要とする。   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.

本発明は強度を高くした上で、前記欠点を解消することを課題にする。   This invention makes it a subject to eliminate the said fault, after raising intensity | strength.

本発明の第1の手段は、複数のプラスチック製セグメントをボルトおよびナットにより接続する組立プールにおいて、各セグメントを周壁と底部を有する同一形状の1対のセルを接続して形成し、しかも各セルをポリエチレン樹脂をブロー成形して中空部を有する二重構造にし、また前記中空部の周壁を部分的に一体化してなる第1補強手段を形成し、前記中空部を有する底部の床板と接地板を部分的に連結する第2補強手段を形成し、さらに各セルの対向端の上面に係合用段部、対向外面に凹部を形成し、前記凹部および対向内面にボルト挿通孔を穿設し、外向鍔付きブッシュのブッシュ部を前記対向内面および前記対向外面により形成される中空部に入れるとともに鍔部を前記凹部に係止し、鍔なし端部を前記対向内面に当接し、ボルトを前記ボルト挿通孔および前記外向鍔付きブッシュ内を貫通し、ナットで締着することを特徴とするものである。 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 the formation of the second reinforcement means you partially connected, further engaging step portion on the upper surface of the opposite ends of each cell, and forming recesses in opposing outer surface, drilled bolt insertion holes in the recess and the opposing inner surface The bush portion of the bush with an outward flange is inserted into a hollow portion formed by the opposed inner surface and the opposed outer surface, the flange portion is locked to the concave portion, and the flange-less end portion is in contact with the opposed inner surface. The bolt insertion hole and through said outward flange with a bushing, is characterized in that fastened in the nut.

本発明の第の手段は、第の手段において、ボルトおよびナット締め作業用の凹陥部を各ボルト・ナットごとに形成し、前記凹陥部に防水キャップを嵌脱自在に設けることを特徴とするものである。 The second means of the present invention is characterized in that, in the first means, a recessed portion for tightening a bolt and a nut is formed for each bolt and nut, and a waterproof cap is provided in the recessed portion so as to be detachable. To do.

本発明の第の手段は、第の手段において、各コーナーセルに有底凹孔を形成し、所望により穿設するとともに前記穿設孔に第2閉栓を着脱自在に設けることを特徴とするものである。 A third means of the present invention is characterized in that, in the first means, a bottomed concave hole is formed in each corner cell, and if necessary, a second plug is detachably provided in the hole. To do.

本発明はポリエチレン樹脂による中空部を有する二重構造であるとともに第1および第2の補強手段を有しており、耐水性が良好で、かつ強度が高い上に、重量が小さく、組立・運搬・保管が容易であり、また1個のセグメントを同一形状の1対のセルで形成するので、分解状態ではさらにコンパクトになり、より運搬および保管がしやすく、しかもコーナーセルのみを組み合わせたプールを製造する場合には一種類の金型、コーナーセルと中間セルとを組み合わせたプールを製造する場合には二種類の金型で足り、かつFRP製に比べて極めて容易かつ迅速に製造することができ、しかも容易に粉砕してリサイクル化することもでき、また強度が高いにもかかわらず、FRPに比べ硬度が低く、遊泳者によるプール内外での衝突等、強い衝撃が加わっても弾力性による回避が可能であり、負傷するおそれがない。   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.

さらに本発明は中空部を有する二重構造でありながら、ボルト・ナット締結部において、各対向端の中空部にブッシュを入れるとともに前記ブッシュの外向鍔部を凹部に係止し、鍔なし端部を対向内面に当接するので、ボルト・ナットをいくら強く緊締しても中空部を有する各対向端が変形することがなく、各セルを確実に接続することができる。   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.

た各コーナーセルに有底凹孔を形成するので、所望の位置の有底凹孔を容易に穿設して閉栓し、プール使用後に開栓すれば泥抜きをすることができ、不要個所には穿孔作業をしなくて足りるものである。
Since forming a bottomed concave hole in each corner cell was or was stoppered and easily bored bottomed concave hole at a desired position, it is possible to mud vent if unplugging after pool use, unnecessary location There is no need for drilling work.
