Abstract
Abstract A plurality of arch bend pipes are erected in order to make a dome-like pipe house, which is used for agricultural purposes. A plurality of straight pipes are fixed to the frame structure of the pipe house so as to cross the bend pipes with the intersecting points of the both pipes being firmly fixed. An improved fixing method for the intersecting points and an improved fixing apparatus for both pipes of the points and the end portions of the bend pipes and base members or the ground are provided. The fixing devices or fittings are mounted on the bend pipe and tensed by means of a connecting means such as wire and a tensioning device is mounted at least on the end portion of the connecting means. When the tensioning device is operated, a plurality of fixing devices function at the same time in order to tense or loosen the tensioning device. At the end portions of the bend pipe, a fixing or securing device is mounted, which is adapted to prevent any movement of the bend pipes during the tensioning of the intersecting pipes. The securing device is cooperatively connected to the tensioning device, so that as the tensioning device is effectively operated, both ends of the bend pipe are firmly secured to the ground or base member.
