[Problems to be solved by the device]

 However, in the above-mentioned prior art, in the former case, in order to lock the reinforcing rib locking portions 11 and 11 to the reinforcing ribs 30 of the deck plate 29 during construction, first, as shown in FIG. The diagonal portions 15a, 15a of the above are engaged with the notches 14, 14 of the reinforcing rib engaging portions 11, 11, and in this state, the upper portions of the reinforcing rib engaging portions 11, 11 are slightly moved in the direction of arrow a. It is rotated and temporarily fixed with the screw 12 and the nut 13 with a seat, and then the reinforcing rib locking portions 11 and 11 are locked to the reinforcing ribs 30 of the deck plate 29 as shown in FIG. Tighten the nut 13 with a seat, screw the upper end of the hanging bolt 16 into the upper nut 15 as shown in FIGS. 9 and 10, and tighten the lower nut 17 to fix it. And in the latter case, as shown in FIG. The strong rib locking members 19 and 19 are left open, and then the notch portions 18 and 18 for locking the reinforcing ribs of the frame-shaped reinforcing rib locking members 19 and 19 are set as shown in FIG. After being locked to the reinforcing ribs 30 of the holder 29, the frame-shaped reinforcing rib locking members 19 and 19 are tightened with the screw 23 and the seat nut 24, and further, as shown in FIG. Since the upper end of the hanging bolt 26 is screwed into the nut 25 and the lower nut 28 is tightened and fixed to complete the construction, in the case of the above-described conventional technique, the reinforcing rib engaging portions 11, 11 ( The former) or the reinforcing ribs The screws 12, 23 and the nuts 13, 24 for attaching the locking members 19, 19 (the latter) to the reinforcing ribs 30 of the deck plate 29 are required, which makes the structure complicated. , Many parts are required Not only there is a problem that, handling property is also rather poor, the result is trouble in the mounting work on the deck plate reinforcing ribs consuming, there is a problem of equal those that wrote rather low workability.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a deck plate suspension fitting having a pair of reinforcing rib locking portions made of elastic pieces on the upper part and suspension bolts on the lower part. The reinforcing rib engaging portions are bent inward at a predetermined angle above the mounting portion of the hanging bolt to form an intersecting state, and one side surface of the engaging portion in the intersecting state and each engaging portion of the other side. The side surface of the connecting piece portion of is exposed to the extension line of the upper end of the suspension bolt.

【Example】

 1 to 5 are views showing 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. 3 is a perspective view, FIG. 4 is a front view showing a state before completion of mounting of a deck plate to a reinforcing rib, and FIG. FIG. 3 is a front view showing the state of FIG.

In each drawing, reference numeral 1 denotes a hanging metal fitting body, which is formed of a required metal plate (iron, steel plate, aluminum plate, other appropriate alloy plate) or a hard plastic plate, and has a required length and a required width in an upper portion. It has a pair of reinforcing rib engaging portions 2.2 made of elastic pieces and has an upper nut 4 for attaching the hanging bolt 3 to the lower portion. The reinforcing rib locking portions 2 and 2 are bent inward at a predetermined angle above the hanging bolt 3 to be in a crossed state, and the side surface 2a of one locking portion 2 and the other side. The side surface 2d of the connecting piece portion 2c having a required width for integrally connecting the inner edges 2b of the respective locking portions 2 is made to face the upper extension line Y of the hanging bolt 3. The shapes of the reinforcing rib engaging portions 2 and 2 may be arbitrary according to the shape of the reinforcing rib B of the deck plate A. Reference numeral 5 denotes a lower nut for fastening and fixing the suspension bolt 3, and 3a denotes an upper end portion of the suspension bolt 3.

Next, the operation will be described. When attaching the deck plate A to the reinforcing rib B, first, the reinforcing rib locking portions 2 and 2 of the hanging fitting body 1 are locked as shown in FIG. 4, and then the hanging bolt 3 is rotated in the upward direction. Then, the side surface 2 a of the one reinforcing rib locking portion 2 and the side surface 2 d of the connecting piece 2 c of the other reinforcing rib locking portion 2 located on the upper end extension line Y of the hanging bolt 3 are the upper ends of the hanging bolt 3. The reinforcing ribs 2 and 2 are pressed by 3a, and the tilted postures of the reinforcing rib locking portions 2 and 2 are in the respective standing states against the spring force. The gripping force is strengthened so that the hanging metal fitting body 1 can be firmly attached as shown in FIG.

Although the present embodiment has been described with respect to mounting on the deck plate, it goes without saying that it can be used for other than the deck plate.

[Effect of device]

 According to the present invention, a pair of reinforcing rib engaging portions are provided on the upper portion of the pair of reinforcing rib engaging portions and elastic portions are provided on the lower portion of the hanging bolts. Bending inward at a required angle above each other to form a crossed state, one side of the locking part in the crossed state and the side of the connecting piece of each of the other locking parts are connected to the suspension bolt. Since it is exposed on the extension line of the upper end, the mounting bracket body can be attached by simply rotating the hanging bolts by operating the pair of reinforcing rib engagement parts left and right simultaneously and evenly left and right. Since it can be performed, it has excellent handling properties compared to conventional products, and as a result, mounting work can be performed easily and quickly, and even a small number of people can greatly improve work efficiency. Suspended metal fittings with The structure of the body is simple and the number of parts is small, so the material can be saved, the economic effect is great, and it can be supplied at low cost. Since the locking portion is integrally formed by the connecting piece portion, it has various advantages such as being strong in strength.
