PURPOSE:To obtain the subject structure, capable of firmly fixing branch pipe parts to a sidewall part during construction of the sidewall part of the main pipe and useful for aircraft, etc., by firmly bonding and integrating the sidewall part of the main pipe to the bottom using part of a yarn forming the bottom of the main pipe as a vertical yarn in the sidewall part of the main pipe. CONSTITUTION:The objective structure, consisting of a bottomed hollow main pipe (3a) and cylindrical branch pipes (4a) outwardly projecting from the sidewall part (2a) of the above-mentioned main pipe and obtained by using a yarn forming the bottom of the main pipe (3a) as a vertical yarn continuously forming the sidewall part (2a) of the main pipe, winding a yarn in the longitudinal direction of separately prepared cylindrical branch pipes (4a) around the sidewall part (2a) of the main pipe as part of the laminating yarn in the sidewall part (2a) of the main pipe. |
