Fig. 20 is a state diagram of the 0 degree winding operation of the filament yarn of the strut making apparatus of the present invention, and Fig. 21 is a partial enlargement detail view of the mandrel 260 used in the operation of Fig.

As shown in FIGS. 20 to 21, a plurality of guide pins 261 are radially fixedly mounted on both ends of the mandrels 260 and 260, respectively.

A plurality of guide pins 261 mounted at both ends of the mandrels 260 and 260 are mounted so as to correspond to each other.

When the filament yarn is moved in the longitudinal direction of the mandrels 260 and 260, the filament yarn is once applied in the longitudinal direction of the mandrels 260 and 260, When the filament yarn is moved in the longitudinal direction of the mandrels 260 and 260, the mandrels 260 and 260 are coated twice in the longitudinal direction.

More specifically, since the guide part 250 for guiding the filament yarn to be wound on the mandrels 260 and 260 is installed on the moving frame 230, The mandrels 260 and 260 are rotated by a set angle once and then the movable frame 230 is driven in the opposite direction of the movement of the mandrel 260, The filament yarns are wound on the mandrels 260 and 260 at an angle of 0 °.

At this time, the movable frame 230 is moved by the number of the guide pins 261 mounted, and when the mandrels 260 and 260 are rotated by -1, the mandrels 260 and 260 are rotated The filament yarn is wound once.

That is, if 24 guide pins 261 are mounted on the outer circumferences of the mandrels 260 and 260, the moving frame 230 moves linearly 24 times, and the mandrels 260 and 260 are rotated 23 times It means to drive.

Meanwhile, if the filament yarn is subjected to a 0 ° winding operation in a direction parallel to the longitudinal direction of the mandrels 260 and 260, the filament yarns do not completely adhere to the mandrels 260 and 260, A predetermined interval is formed from the surface of the mandrel 260. After the outer periphery of the mandrels 260 and 260 is laminated about one to three times as a filament yarn, the filament yarns are wound in the spiral direction about one to two times It is possible to solve the problem that the gap between the filament yarns and the mandrels 260 and 260 is formed and also the strut 100 or the street lamp manufactured by winding the filament yarn can be more firmly manufactured.

The filament yarn is made of carbon fiber or glass fiber and resin, and carbon fiber or glass fiber and resin are preferably composed of 60-70: 30-40 wt%.

The resin may be selected from the group consisting of epoxy, polyethylene, and vinyl ester.

As described above, the pillars fabricated by the method of the present invention are made of glass fiber and resin, and are light, rust free, excellent in insulation property to prevent electric shock, and have excellent appearance and appearance due to light transmittance There is a remarkable effect.
