The upper end portion of the brace material 97 is fixed to the upper end portion of the suspension portion 4. The lower end portion of the brace material 97 is fixed to the field edge receiver 93. The brace member 97 is made of, for example, groove steel (so-called channel) or equilateral mountain steel (so-called angle).

  In such a structure, when an earthquake or the like occurs and the ceiling board 91 is shaken in the horizontal direction, the horizontal shake is restricted by the field edge receiver 93, the brace material 97, and the suspension part 4. At this time, the force of the shaking is transmitted to the hanging metal fitting 1 via the hanging portion 4.

  In the hanging metal fitting 1, the abutting portion 23 abuts on the lower surface of the valley portion 52 of the folded plate roof 5, and the hook portion 26 is engaged with the engaged portions 56 on both sides of the valley portion 52. The hooking portion 26 is in contact with the locked portion 56 over the entire length in the width direction. For this reason, the suspension metal fitting 1 of the present embodiment improves not only the strength against the downward load but also the rolling, and as a result, the ceiling material can be regulated.

  As described above, the hanging metal fitting 1 of the present embodiment is used to suspend the suspended object 9 from the folded plate roof 5. The folded plate roof 5 is attached to the tight frame 6. The tight frame 6 is provided with a convex portion 61. Locking portions 64 are provided on the inclined surfaces 631 facing each other between the convex portions 61 that are separated from each other.

The hanging metal fitting 1 includes a contact portion 23, a hooking portion 26, and a hanging portion 4. The abutting portion 23 abuts on the lower surface of the valley portion 52 of the folded plate roof 5 and is attached so as to straddle the valley portion 52. The hook portions 26 are provided at both ends of the contact portion 23 in a direction perpendicular to the roof gradient direction. Further, the hooking portion 26 engages with the locked portions 56 provided on both sides of the valley portion 52 of the folded plate roof 5. The hooking portion 26 is formed in a planar shape along the roof gradient direction of the folded plate roof 5. When the hook portion 26 is engaged with the locked portion 56, the hook portion 26 contacts the locked portion 56 over the entire length in the roof gradient direction.

  For this reason, the hanging metal fitting 1 of this embodiment is firmly attached to the lower surface of the valley portion 52 of the folded plate roof 5. In particular, the contact portion 23 is in contact with the lower surface of the valley portion 52, and the entire length in the roof gradient direction at the tip of the planar hooking portion 26 is in contact with the locking portion 64 of the folded plate roof 5. The strength can be improved with respect to the lateral and lateral rolls of the suspension part 4. Thereby, also when an earthquake etc. occur, the swing of the to-be-suspended thing 9 can be suppressed as much as possible.

  Further, the upper surface of the contact portion 23 of the hanging metal fitting 1 of the present embodiment is a planar contact surface 300 that contacts the lower surface of the valley portion 52 of the folded plate roof 5.

  For this reason, according to the hanging metal fitting 1 of this embodiment, intensity | strength can be strengthened with respect to the rolling of the hanging metal fitting 1 further, and the rocking | fluctuation of the to-be-suspended thing 9 can be suppressed.
