Claims

[Scope of utility model registration request]

A pair of mounting members A and B for symmetrically mounting on either the upper or lower flanges of the H-shaped steel, and a locking tool for removably securing the pair of mounting members to either the upper or lower flange of the H-shaped steel. One of the attachment members A has net frame rope attachment hooks 12 fixedly protruded at multiple locations in the longitudinal direction of one side of the attachment main body 11, and
Attaching a U-shaped fitting piece 13 that can be fitted to a flange of H-shaped steel on the surface opposite to the mounting surface of the hook,
A wire insertion ring portion 15 is protruded and fixed below near the longitudinal center of the fixture main body, and a chain 27 is wrapped around and fixed to the other mounting member B in the longitudinal direction of one side of the fixture main body 21. Hooks 22 for attaching the net frame rope are fixedly protruded from a plurality of locations, and ring portions for wire insertion are protruded near the ends and the center in the longitudinal direction, and the attachment main body 11 is provided on the surface opposite to the attachment surface of the hook. U-shaped fitting piece 23 similar to
The wire C with a locking device for bondage is formed by protruding from the ring portion 15 for wire insertion of one mounting member A,
A safety net attachment device configured to pass through the wire insertion ring portion of the other attachment member 3 via the H-shaped steel 1, and to securely bind the locking portion 32 at the tip to the chain 27 so as to be lockable thereto.
