Description

[Detailed Description of the Invention] The present invention relates to a field edge holding metal fitting for attaching a field edge orthogonally to a field edge support fixed to the lower side of a ceiling slab.

Conventionally, a ceiling frame in a building with a reinforced concrete structure has a structure shown in FIG. That is, in FIG. 1, 1 is a bolt buried in the ceiling slab 2 side, and a hanger 3 is attached to this bolt 1.
is fixed with a nut (not shown), and a field edge support 5 is placed on the U-shaped holding part 4 at the bottom of the hanger 3. Movement of this field edge support 5 toward the ceiling slab 2, that is, upward, is as follows. It is regulated by inserting bolts (not shown) into the through holes 4a, 4b of the holding part 4 and tightening nuts onto the bolts. Therefore, Noen Uke 5
is suspended and fixed to the ceiling slab 2 by a hanger 3. Further, a field edge 6 is attached to the field edge support 5 by means of a field edge holding fitting 7 in a perpendicular state. The field edge 6 is formed by bending a band-shaped metal plate to form a prismatic shape having a band-shaped opening 8 on the top surface, and bending both ends of this opening 8 inward to form bent pieces 9, 9.
is formed. Locking pieces 10, 1 formed on both sides of the lower part of the field edge holding fitting 7 are attached to the bent pieces 9, 9.
Hook 0. Further, the field edge holding fitting 7 has a strip-shaped mounting piece 1 extending upwardly of the locking pieces 10, 10.
1, and in order to attach it to the field edge support 5, both corner edges 12a, 12a of the horizontal piece 12 on the upper side of the field edge 5 are attached.
It is fixed by bending inward using the point corresponding to the fulcrum as a fulcrum.

Therefore, the field edge retaining metal fitting 7 in the ceiling frame structure described above has a structure in which a part thereof is simply bent and fixed to the field edge support 5, so although it is easy to construct, it is difficult to hold the field edge 6. When an external force that pushes up or pushes down, for example, a large wind pressure that blows up or down is applied to a ceiling board attached to the roof edge, the folded portion of the roof edge holding bracket 7 is caused by the vibration of the roof edge 6 in the vertical direction. 11a sometimes becomes loose and falls off.

In order to eliminate the above-mentioned drawbacks, the present invention has been developed by straddling the field edge holder fixed to the ceiling slab, locking the field edge in a perpendicular state from both sides of the field edge holder, and by screwing in bolts, etc. Not only does it have good workability by bringing the field edge into contact with the field edge receiver, but it also reliably maintains the connection between the field edge and the field edge receiver even when vertical and horizontal vibrations are applied to the field edge. A field edge holding metal fitting is provided.
