In addition to the screws 12, 23 and the seat nuts 13, 24 for attaching the (the latter) to the reinforcing ribs 30 of the deck plate 29, the structure becomes complicated and the number of parts is increased. In addition, the handleability is poor, and as a result, there is a problem that the work for mounting the ribs on the deck plate reinforcing ribs is troublesome and the workability is extremely low.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problem, and to form an opposing reinforcing rib engaging portion made of an elastic piece on an upper portion with a part of a plate material.
In particular , in a hanging metal fitting for a deck plate provided with hanging bolts at a lower portion, the opposing reinforcing rib engaging portions are bent inwardly at a required angle to each other above the hanging bolt mounting portion in a crossed state. Further, one side surface of the locking portion in the crossed state and the side surface of the projecting piece formed on the side edge of the other locking portion face the upper end extension line of the suspension bolt.

1 to 5 show an embodiment of the present invention. FIG. 1 is a front view of the present invention, FIG. 2 is a right side view of the same, FIG.
4 is a perspective view, FIG. 4 is a front view showing a state before the deck plate is completely mounted on the reinforcing ribs, and FIG. 5 is a front view showing a state after the completion of the mounting.

In each of the drawings, reference numeral 1 denotes a hanging bracket main body, which is formed of a required metal plate (iron, steel plate, aluminum plate, or other appropriate alloy plate) or a hard plastic plate, and has a required length and a required length on an upper portion. It has opposing reinforcing rib locking portions 2 and 2 made of elastic pieces having a width, and is provided with an upper nut 4 for attaching a lower suspension bolt 3. The reinforcing rib engaging portions 2 and 2 are bent inwardly at a required angle to each other above the hanging bolts 3 to be in a crossing state, and the side surface 2a of one of the engaging portions 2 and the other are connected to each other. The side surface 2d of the protruding piece 2c formed on the side edge 2b of the locking portion 2 is connected to the upper end extension line Y of the suspension bolt 3.
I'm facing up. The shape of the reinforcing rib engaging portions 2 and 2 can be designed according to the shape of the reinforcing rib B of the deck plate A. Reference numeral 5 denotes a lower nut for tightening and fixing the suspension bolt 3, and reference numeral 3a denotes an upper end of the suspension bolt 3.

Next, the operation will be described. When attaching the deck plate A to the reinforcing ribs B, first, the reinforcing rib locking portions 2 and 2 of the hanging metal body 1 are locked as shown in FIG. 4, and then the hanging bolts 3 are rotated in the ascending direction. Then
The side surface 2a of one of the reinforcing rib locking portions 2 and the side surface 2d of the protruding piece 2c of the local reinforcing rib locking portion 2 located on the extension line Y of the upper end of the hanging bolt 3 are fixed by the upper end 3a of the hanging bolt 3. The reinforcing rib locking portions 2, 2 are pressed against each other, and the tilting postures of the reinforcing rib locking portions 2, 2 are set in the upright state, and the reinforcing ribs B of the deck plate A are fixed by the reinforcing rib locking portions 2, 2.
The gripping force is strengthened, and the hanging bracket main body 1 can be securely attached as shown in FIG.

Although the present embodiment has been described with respect to the attachment to the deck plate, it is needless to say that the present invention can be applied to anything other than the deck plate.

[0009]

[Effect of the Invention] According to the present invention, a plate made of one member is used.
At the top there is an opposing reinforcing rib locking part consisting of an elastic piece
In a hanging metal fitting for a deck plate, which is formed and provided with hanging bolts at a lower portion, the opposing reinforcing rib locking portions are bent inwardly at a required angle to each other above the hanging bolt mounting portion in an intersecting state. And the side surface of one of the engaging portions in the crossed state and the side surface of the projecting piece formed on the side edge of the other engaging portion face the extension line of the upper end of the suspending bolt. mounting is simply only opposite the reinforcing Li rotating hanger bolts
The locking part can be operated left and right at the same time, and left and right equally, so it is very easy to handle as compared with conventional products, and as a result, mounting work is easy and quickly it can be carried out, along with those which can be significantly improved work efficiency in a small number, the opening and closing of the reinforcing rib engaging portion
The operation is performed by locking one of the crossed portions of the reinforcing rib locking portion.
On the side of the protruding piece formed on the side of the
By the pressing and separating action of the upper end of the hanging bolt
Therefore, it is reliable, and also the reinforcing rib locking portion
The vertical movement distance of the suspension bolt for opening and closing
Work), so work can be done more quickly.
In addition , since the structure of the hanging bracket main body is simple and the number of parts is small, materials can be saved, the economic effect is large, and there are various effects such as cheap supply.
