METHOD FOR PRODUCING COLLECTIVE JOINT WITH COVER AND COLLECTIVE JOINT
To secure workability and sound insulation performance.SOLUTION: A sound insulation cover 20 has an upper sound insulation cover 21 arranged on an outer surface of an upper connection pipe 11 and a lower sound insulation cover 22 arranged on an outer surface of a lower connection pipe 12. The upper sound insulation cover 21 has a sheet shape formed of an elastic material, and the lower sound insulation cover 22 comprises a pipe body 31 arranged on an outer circumference of the lower connection pipe 12, and a sheet body arranged between the lower connection pipe 12 and the pipe body 31. In a step for attaching the sound insulation cover 20 to a collective joint 1, a step in which the lower connection pipe 12 is inserted through the inside of the lower sound insulation cover 22 and then a step in which the upper sound insulation cover 21 is wound and attached from outside in a radial direction of the upper connection pipe 11, are performed.SELECTED DRAWING: Figure 2
【課題】施工性および遮音性能を確保する。【解決手段】遮音カバー２０は、上部接続管１１の外面に配置された上部遮音カバー２１と、下部接続管１２の外面に配置された下部遮音カバー２２と、を有し、上部遮音カバー２１は、弾性を備えた材料で形成されたシート状であり、下部遮音カバー２２は、下部接続管１２の外周に配置される管体３１と、下部接続管１２と管体３１の間に配置されるシート体と、を備え、集合継手１に遮音カバー２０を取り付ける工程が、下部遮音カバー２２内に下部接続管１２を挿通させる工程と、次に、上部遮音カバー２１を上部接続管１１の径方向の外側から巻きつけて取り付ける工程と、を行う。【選択図】図２
