STRUCTURE

To provide a structure in which both ends of an additional horizontal pipe can be coupled between vertical pipes to which both ends of a horizontal pipe are coupled already, more easily.SOLUTION: A horizontal pipe coupling tool 2 fitted to a vertical pipe 1 comprises: a fitting cylinder 10 which is detachably fitted to a periphery of the vertical pipe 1; and engagement protrusions 11, 12 provided on the fitting cylinder 10. The fitting cylinder 10 is formed of first and second divided bodies 14, 15 obtained by dividing the fitting cylinder into two bodies in a peripheral direction, the first and second divided bodies 14, 15 comprise: a first divided protrusion 16/second divided protrusion 17 in one end part in the peripheral direction, and the other end part of the divided bodies in the peripheral direction are coupled by a hinge shaft 10a. In a state of assembling the first and second divided bodies 14, 15 into a cylindrical state, the first and second divided protrusions 16, 17 form an engagement protrusion 12. There is provided a C-shaped joint part 22 capable of accommodating the engagement protrusions 11, 12 on an end part of the first horizontal pipe 3.SELECTED DRAWING: Figure 7 【課題】既に水平パイプの両端が接続されている鉛直パイプの間に、さらに追加の水平パイプの両端を接続する作業が容易となる構造体を提供する。【解決手段】鉛直パイプ１に取り付けられる水平パイプ接続具２が、鉛直パイプ１の外周に着脱可能に嵌合する嵌合筒１０と、嵌合筒１０に設けられる係合突起１１、１２とを有し、嵌合筒１０が周方向に二分割された第一分割体１４、第二分割体１５で構成され、第一分割体１４および第二分割体１５は、周方向一方端部に第一分割突起１６および第二分割突起１７を有し、周方向他端部がヒンジ軸１０ａにより連結されており、第一分割体１４および第二分割体１５を筒状に組み合わせた状態で、第一分割突起１６および第二分割突起１７が係合突起１２を形成し、第一水平パイプ３の端部に係合突起１１、１２を受け入れ可能なＣ形状のジョイント部２２を有する構造体。【選択図】図７
