Bracket for utilities support hardware
View Patent ↗A bracket for utilities hangers and sway braces suspended below a fluted deck includes a bracket plate having attachment holes therethrough spaced apart by the known pitch of the fluting on the deck. A mount is positioned in the plate. One or more flute keys extend perpendicular to the mounting plate and have two sides which are tapered away from the plate toward one another to fit within one or more flutes in the deck.
1. A bracket for a utilities support suspended below a fluted deck of a known pitch and flute contour, comprising
a plate including a length greater than the known pitch, attachment holes therethrough spaced apart by the known pitch and a mount;
a first flute key on the plate including two first sides tapered away from the plate toward one another, in interfering fit within a width of the known flute contour, being attached between the two first sides to the plate and extending perpendicular to the plate where attached, the first flute key further including a symmetrical centerline extending perpendicular to the plate between the two first sides, the symmetrical centerline being equally spaced from the attachment holes, the fluted deck having flutes of a known depth, the first flute key extending from the plate by less than the known depth.
2. The bracket of claim 1 , the mount being a mounting hole through the plate.
3. The bracket of claim 1 , the first flute key extending perpendicular to the plate in a first direction, the mount extending perpendicular to the plate in a second direction and including at least one mounting hole extending through the mount perpendicular to the first flute key.
4. The bracket of claim 1 further comprising
a second flute key on the plate including two second sides in interfering fit within the width of the known flute contour, the flute keys being adjacent at opposite edges of the plate.
5. The bracket of claim 1 further comprising
a second flute key displaced one known pitch from the first flute key on the plate and including two second sides closely fitting within the width of the known flute contour, the plate being longer than twice the known pitch.
6. The bracket of claim 5 , the first flute key and the second flute key lying in a common plane.
7. The bracket of claim 1 , the mount being centered on the plate between adjacent attachment holes.
8. The bracket of claim 1 further comprising
a second flute key displaced one known pitch from the first flute key on the plate and including two second sides tapered away from the plate toward one another, closely fitting within the width of the known flute contour, being attached between the two first sides to the plate and extending perpendicular to the plate where attached and a second symmetrical centerline extending perpendicular to the plate between the two second sides, the two second sides being spaced from one another at the plate by less than the known pitch, the plate being longer than twice the known pitch.
9. A bracket for a utilities support suspended below a fluted deck of a known pitch and flute contour, comprising
a plate including a length greater than two of the known pitch, three attachment holes therethrough spaced apart in series by the known pitch and a mount;
two flute keys on the plate displaced one known pitch from one another, each flute key including two sides tapered away from the plate toward one another, in interfering fit within a width of the known flute contour, being attached between the two first sides to the plate and extending perpendicular to the plate where attached and a symmetrical centerline extending perpendicular to the plate between the two sides, the two sides being spaced from one another at the plate by less than the known pitch, the symmetrical centerline being equally spaced between two adjacent attachment holes, the fluted deck having flutes of a known depth, the flute keys extending from the plate by less than the known depth.
10. The bracket of claim 9 , the flute keys lying in a common plane.
11. The bracket of claim 9 , the mount being a mounting hole through the plate.
12. The bracket of claim 9 , the first flute key extending perpendicular to the plate in a first direction, the mount extending perpendicular to the plate in a second direction and including at least one mounting hole extending through the mount perpendicular to the first flute key.
