フィルム巻上げパイプＡが構成される。The end portion of the one pipe material 1 to be connected is transformed into an inner fitting portion 2 by being deformed into a substantially rhombic cross section.
The end portion of the other pipe material 1 to be connected is deformed into a substantially rhombic cross section to form an outer fitting portion 3. As a method of deforming the end portion of the pipe material 1 into a substantially rhombic cross section, swaging or the like is suitable. Further, usually, the inner fitting portion 2 is formed at one end of one pipe material 1 and the outer fitting portion 3 is formed at the other end. Then, as shown in FIG. 2, the inner fitting portion 2 and the outer fitting portion 3 are fitted to each other to connect the adjacent pipe members 1 and 1,
A film winding pipe A is constructed.

The polyethylene in the swaged portion of the inner fitting portion was peeled off in advance over a length of 90 mm from the end. In addition, one end of the same pipe material is swaged with a rhombus cross section (internal width 20.6 mm, internal length 14.5 mm) over a length of 85 mm to form an outer fitting portion, and the tip end. A coated cylindrical portion having a length of 15 mm was formed on the surface.

When the pipe material on the inner fitting portion side was rotated and the rotational torque generated at the fitting portion was measured, it was 700 kgfcm or more. In addition, the portion of the inner fitting portion where the polyethylene was peeled off was sufficiently covered with the outer fitting portion and the covering cylinder portion to be protected from rainwater and the like.

The outer fitting portion was formed by performing swaging with an elliptical cross-section (internal dimension lateral width 19.8 mm, internal dimension vertical width 14.0 mm). After connecting the two pipe materials through the inner fitting part and the outer fitting part, fix the pipe material on the outer fitting part side and rotate the pipe material on the inner fitting part side to When the rotational torque generated in the above was measured, the outer fitting portion bulged in a circular cross section at 472 kgfcm, and slip occurred between the outer fitting portion and the inner fitting portion.

る。As described in detail above, in the film windup pipe for ventilation of a vinyl house of the present invention, a plurality of synthetic resin-coated metal pipe members each having a substantially circular cross section are connected, and one end of one of the connected pipe members has a cross section. The inner fitting portion is transformed into a substantially diamond shape to form an inner fitting portion, and the end portion of the other pipe material to be connected is transformed into a substantially diamond shape in cross section to form an outer fitting portion. Since a plurality of pipe materials are connected and integrated through and, even if a rotational torque is applied when the film is wound, the outer fitting portion having a rhombic cross-section does not easily deform into a circular shape or the like. Is reliably transmitted to the other pipe material, so that the film can be smoothly wound.
