Description of the Related Art A ceiling hanging fitting of this type is bent from the left and right ends of a bottom plate portion having a screw hole through which a suspension bolt is screwed into such that a middle portion approaches each other in a symmetrical shape. There has been proposed a ceiling suspension metal fitting for a deck plate in which a pair of left and right bent side plates are connected in series, and the two bent side plates are pushed open by a hanging bolt screwed through the screw hole.

業性が悪かった。In this type of conventional ceiling hanging bracket, the virtual plane shape surrounding the upper ends of the both bent side plates is substantially square, and the upper halves of the both bent side plates are inserted into the dovetail groove of the deck plate. In the fitted state, the suspension bolts screwed into the screw holes of the bottom plate cannot be engaged with the dovetail unless the both bent side plates are pushed open by screwing. Therefore, it is not only impossible to temporarily fix a metal fitting without a hanging bolt to the dovetail groove portion of the deck plate so as not to fall and to be movable in the groove length direction, and also when screwing the hanging bolt. In this case, it was necessary to hold the lower end of the metal fitting by hand to prevent it from rotating, resulting in poor workability.

Is limited. However, since both the bent side plate portions 5 can be elastically deformed in a direction approaching each other with the lower end connected to the bottom plate portion 4 as a fulcrum, by increasing the rotational operation force from the time when the rotation is limited as described above, The bent side plates 5 can be further rotated while being elastically deformed in directions approaching each other.

The upper end 5a of each of the dovetail grooves 8 is parallel to the inner rear portion 8a on both sides of the dovetail groove 8, and the upwardly extending inclined portions 5c of the both bent side plates 5 are fitted into the inner rear portions 8a on both sides of the dovetail groove 8. Becomes Rotating the ceiling hanging bracket 1 further in the same direction (the direction of the arrow R) beyond this locking posture requires the rotation of the upper end 5a of the both bent side plate portions 5 corresponding to both ends of the long diagonal line L1 shown in FIG. 1B. The anti-rotation side corners 5ab (see FIG. 5) are strongly and reliably prevented by contacting the inner depths 8a on both sides of the dovetail groove 8, so that the ceiling hanging bracket 1 is manually screwed in the anti-screw direction (arrow R and The ceiling hanging bracket 1 does not accidentally reversely rotate due to vibration or the like, and does not fall out of the dovetail groove 8 unless it is rotated strongly in the opposite direction.

Its position can be adjusted. The suspension bolt 2 is screwed upward into the screw hole 3 of the bottom plate 4 of the ceiling suspension fitting 1 whose position has been adjusted. At this time, the temporarily suspended ceiling hanging bracket 1 cannot be rotated in the screwing direction (the direction of the arrow R) of the hanging bolt 2 as described above, so that the ceiling hanging bracket 1 is held by hand to prevent co-rotation. Without doing so, the suspension bolts 2 can be securely screwed through the screw holes 3 of the ceiling suspension fitting 1.

付けることが出来る。The suspension bolts 2, which are screwed through the screw holes 3 upward, come into contact with the bent portions 5b of the both bent side plates 5, and push the bent side plates 5 apart from each other.
At this time, the space between the opposing inner edges 6a of both upper end plate portions 6 spreads to a degree slightly larger than the diameter of the suspension bolt 2, so that the suspension bolt 2 is further screwed and the upper end thereof is attached to the ceiling portion 8c of the dovetail groove portion 8. You can make contact. In this state, the ceiling suspension fitting 1 is moved downward by further screwing the suspension bolts 2, and as shown in FIGS. 1A and 6, the upwardly extending inclined portions of the both bent side plate portions 5 expanded by the suspension bolts 2. 5
c can be brought into pressure contact with both side inclined portions 8 b of the dovetail groove 8. As a result, the suspension bolt 2
Is fixed substantially vertically to the dovetail groove 8 of the deck plate 7, so that a suspended member can be attached to the lower end of the suspension bolt 2.

ない。When the hanging bolt 2 pushes and opens the both bent side plate portions 5, the peripheral surface of the hanging bolt 2 is formed on the both bent side plate portions 5 as shown in FIG. 1A and FIG. Since the ceiling suspension fitting 1 is fitted into the bolt guide groove 9, the ceiling suspension fitting 1 is engaged with the suspension bolt 2 at two positions above and below the screw hole 3 and the recessed groove 9, and the ceiling suspension fitting 1 is connected to the ceiling suspension fitting 1. The hanging bolts 2 surely hold the postures parallel to each other. Also, as shown in FIG.
Since the opposed inner edge 6a of the upper end plate portion 6 is adjacent to the peripheral surface of the bent side plate portion 5, the upwardly expanding inclined portion 5c of the bent side plate portion 5 is prevented from being deformed inward. Therefore, when a large downward load is applied to the suspension bolt 2, there is a possibility that the upwardly extending inclined portion 5 c of the bent side plate portion 5 is deformed inward by the inclined portions 8 c on both sides of the dovetail groove 8 and the suspension bolt 2 is lowered. Nor.

After being fitted, only by strongly rotating in the screwing direction of the suspension bolts, the elastically deformed both bent side plates are used to make the upwardly expanding inclined portions of the both bent side plates in the inner depths on both sides of the dovetail groove. It can be fitted and locked. In this state of engagement and locking, both corners at the upper ends of the both bent side plates abut against the inner depth of the dovetail groove to prevent rotation in either forward or reverse direction. The hanging metal does not accidentally rotate and fall out of the dovetail. In particular, the rotation of the suspension bolt in the screwing direction can be strongly prevented or completely prevented by the contact between the corner at the upper end of the bent side plate portion corresponding to both ends of the longer diagonal and the inner depth of the dovetail portion. Since it is impossible to rotate, the hanging bolt can be screwed into the screw hole of the ceiling hanging bracket without manually stopping the co-rotation of the ceiling hanging bracket.

Adjust the position of the metal fittings in the length direction of the dovetail, and rotate the hanging bolts only to securely screw the hanging bolts into the temporarily suspended ceiling hanging metal, and suspend them through the ceiling hanging metal. The bolt can be fixed at any position in the length direction of the dovetail groove. Therefore, the work of attaching the suspension bolt to the dovetail groove of the deck plate can be performed easily, easily and efficiently.

The upper end plate portions extending inward from the upper end are connected in series, and when the tips of the suspension bolts push open the both bent side plate portions and reach between the upper end plate portions, the opposing inner edges of the both upper end plate portions are formed. By configuring so as to be adjacent to the peripheral surface of the suspension bolt, safety can be improved.
