Swivel fastener
Key words:
The center of the rotating fastener refers to the central position where the rotating fastener is installed on the scaffold frame pipe, and the main node refers to the connection point between the cross bar and the vertical bar of the scaffold pipe. Rotating fastener is used for connecting parallel or oblique crossing rods. Scissors oblique rods shall be fixed on the protruding end or vertical rod of intersecting transverse horizontal rods with rotating fastener. The distance from the center line of rotating fastener to the main node shall not be greater than 150mm. Both ends of flat-shaped and open-shaped double-row scaffolds shall be provided with transverse diagonal braces, and one in the middle shall be provided every 6 spans. The longitudinal overlapping length shall not be less than 1 m, and 3 rotating fasteners shall be arranged at equal intervals for fixation. The distance from the edge of the cover plate of the end fastener to the end of the overlapping longitudinal horizontal rod shall not be less than 100mm.
Key words:
The anti-skid performance of the rotating fastener can ensure a perfect combination between the steel pipe and the rotating fastener, ensure the maximum fit surface, and eliminate the risk of slippage of other fasteners. Rotating fasteners because the skill is a should not be corroded and not easy to be damaged objects, so after the use of maintenance is relatively simple and convenient, but also to a certain extent, reduce the cost of maintenance.
