A bolt 1 is screwed into an insert fitting embedded in a ceiling slab (not shown), a field edge receiver 3 is attached to a field edge receiving hanger 2 attached to the bolt 1, and a field edge attaching tool 4 such as a clip is used. A field edge 5 is attached to the field edge receiver 3. The above-mentioned hangar hanger-2 is shown in FIGS.
As shown in Fig. 2, a mounting piece 2a attached to the bolt 1
And a hanging piece 2b extending downward from the mounting piece 2a
And a horizontal piece 2 extending forward from the lower end of this hanging piece 2b
d and a rising piece 2e that rises above the tip side of the horizontal piece 2d, and is a U-shaped holding portion 2H formed by the lower part of the hanging piece 2b, the horizontal piece 2d, and the rising piece 2e. ,
A field frame receiver 3 having U-shaped cross sections having upper and lower horizontal pieces 3b and 3c on a long substrate 3a is held. Further, the attachment piece 2a is formed with a through hole 2z for allowing the bolt 1 to penetrate therethrough. As shown in FIG.
It is attached to the bolt 1 with 1a. The above-mentioned field reception 3
As shown in FIG. 24, the long substrate 3a is attached to the hanging piece 2
The upper and lower horizontal pieces 3b and 3c are positioned so as to face the b side, and the tips 3t and 3t sides of the upper and lower horizontal pieces 3b and 3c face the rising piece 2e side, and are attached to the holding portion 2H in a fitted state.
In order to increase the holding force of the holding portion 2H, recesses 2c and 2f are formed in the hanging piece 2b and the rising piece 2e where the upper horizontal piece 3b of the field receiver 3 is located. Further, a pressing piece 2h is provided for cutting and raising a part of the recessed portion 2f to press the upper part of the upper horizontal piece 3b on the tip 3t side.

By the way, in the case of a deep ceiling, that is, in the case of a ceiling base structure in which the height from the ceiling slab to the ceiling (board) is sufficient, a maintenance worker regularly performs inspection and maintenance of the ceiling above the ceiling. You have to think that it is necessary to work in. At this time, since the worker rides on the field rim receiver 3 to perform the work, in the field rim mounting structure as described above, as shown in FIG. This causes the rising piece 2e of the field reception hanger 2 to fall forward. as a result,
As shown in FIG. 26, the locking portions 4 a, 4 of the field edge fitting 4 are
b is displaced from the field edge receiver 3 and the field edge 5, and the field edge 5
And the board 6 falls off.

FIG. 27 shows an example of a field support hanger capable of preventing the field support from falling as described above. In FIG. 27, the same parts as those of the above-mentioned field edge hanger 2 are designated by the same reference numerals. It should be noted that this field edge hanger 20 has a recess 2 of the field edge hanger 2 described above.
c, 2f and the pressing piece 2f are not provided. This field edge support hanger 20 prevents the field edge receiver 3 from falling down by fixing the hanging piece 20b and the rising piece 20e with bolts 20m and nuts 20n to reinforce the rising piece 20e. However, the field-hanging hanger 20 requires the bolts 20m and the nuts 20n, and the work of attaching these bolts and nuts is very troublesome, so that the workability is poor.

Further, as still another example of the field hangar hanger capable of preventing the above-mentioned field hangover from falling, FIG.
8 and 29 are available. This hangar hanger 21
Cut out a part of the hanging piece 21b and attach the locking portion 2 to the tip.
A locking rod 21a having 1t and 21t is provided, and the rising piece 2
A notch 21s into which the locking rod 21a is inserted is formed at the upper end of 1e. Note that, similarly to the above-mentioned field receiving hanger 2, 2c is a recessed portion, and 21c is a holding piece. This is because after attaching the field receiver 3 to the holding portion 2H, the locking rod 21a is tilted in the direction of the rising piece 21e and the locking rod 21a is inserted into the cut 21s.
The t is locked to the rising piece 21e. That is, the locking rod 21
The rising piece 21e is connected and fixed to the hanging piece 21b by a. However, in this field support hanger 21, first, the locking rod 21a must be pulled out by a flat head screwdriver or the like, and then the locking rod 21a must be pinched down with pliers or the like to be inserted into the notch 21s. , Workability is very poor. Further, the field support hanger 21 is formed by cutting the locking rod 21a for 21s.
It will not function sufficiently if it is not firmly attached to the, but due to the structure and lack of attention of the worker,
There is a possibility that the locking rod 21a may not be fully retracted,
Further, since the pressing pieces 21c, 21c have a shape with a radius R for inserting the locking rod 21a, there is a great risk that the pressing pieces 21c, 21c will not perform their functions sufficiently. It is doubtful. Further, since the above-mentioned field edge hanger 21 has a part of the hanging piece 21b cut out, there is a major structural defect that the strength is weakened. In addition, since the manufacturing cost is much higher than that of the field hanger 2 shown in FIGS. 23 and 24, even if there is no possibility that a person gets on the back of the ceiling with a narrow ceiling, it is expensive and weak. You will have to use the field hanger 21.
