[Prior art]

For example, as shown in Figure 7, as a conventional deck plate hanging bracket, an elastic part is attached to the upper part. A pair of reinforcing rib locking portions 11, 11 consisting of pieces are provided, and the reinforcing rib locking portions 11 , 11 can be tightened with the screw 12 and seat nut 13, and Notches 14, 14 are provided on the lower side surfaces of the reinforcing rib locking portions 11, 11. The diagonal portions 15a, 15a of the upper nut 15 are engaged with the diagonal portions 14, 14, and the hanging bolt is closed. Screw in the upper end of the bolt 16, and then tighten the hanging bolt 16 with the lower nut 17. A piece that is fixed, or a notch 18 for locking the reinforcing rib as shown in Fig. 12. , 18 are attached to the lower part of the pair of frame-shaped reinforcing rib locking members 19, 19 with hanging bolts. It is pivotally connected to the forked portion 21 of the body 20 by a pivot 22, and the pair of frame-shaped reinforcing ribs are connected to each other. The stop members 19, 19 can be tightened with screws 23 and seat nuts 24. Further, the upper end of the hanging bolt 26 is attached to the upper nut 25 of the hanging bolt attachment body 20. At the same time, tighten and fix the hanging bolt 26 with the lower nut 28. There are some known examples.

[Problem that the idea aims to solve]

However, in the above conventional technology, in the former case, reinforcing ribs are not locked during construction. In order to lock the parts 11, 11 to the reinforcing ribs 30 of the deck plate 29, first, as shown in FIG. As shown in FIG. and in this state, the upper part of the reinforcing rib locking parts 11, 11. Turn the side part a little in the direction of arrow a and temporarily tighten it with the screw 12 and seat nut 13. Afterwards, the reinforcing rib locking portions 11, 11 are reinforced with the deck plate 29 as shown in FIG. 10, and tighten the screw 12 and seat nut 13. As shown in Fig. 11, screw the upper end of the hanging bolt 16 into the upper nut 15, and then attach it to the lower part. The construction is completed by tightening and fixing with the side nuts 17, and in the latter case, the 13, keep the frame-shaped reinforcing rib locking members 19, 19 open, and then FIG. As shown in 4, after locking to the reinforcing rib 30 of the deck plate 29, attach the screw 23 and seat. Tighten the frame-shaped reinforcing rib locking members 19, 19 with nuts 24, and then tighten as shown in FIG. Screw the upper end of the hanging bolt 26 into the upper nut 25 of the hanging bolt mounting body 20 as shown. However, since this was to be tightened and fixed with the lower nut 28 to complete the construction, In the case of the above conventional technology, either the reinforcing rib locking portions 11, 11 (the former) or the reinforcing Attach the rib locking members 19, 19 (latter) to the reinforcing ribs 30 of the deck plate 29 In addition to requiring screws 12, 23 and seat nuts 13, 24 for When attaching the hanging bolts 16 and 26 to the hanging fittings, be sure to Side nuts 15 and 25 are required, which complicates the structure and requires many parts. Not only was there a problem with this, but the handling was also poor, and as a result, the deck plate Problems include the fact that installation work to the reinforcing ribs is time-consuming and workability is extremely low. was there.

[Means to solve the problem]

The purpose of this invention is to solve the above problems. Hanging fittings for deck plates with strong rib locking parts and hanging bolts at the bottom. and place each of the pair of reinforcing rib locking parts above the hanging bolt attachment part. While bending each other inward at a required angle to form a crossed state, one side of the crossed state The side surface of the stop part, and the side surface of the connecting piece of each other stop part are connected to the upper end extension line of the hanging bolt. At the same time, attach the necessary bolts to the hanging bolts of the deck plate hanging bracket. A rising wall for thread cutting is formed, and a hanging bolt is formed on the rising wall for thread cutting. It is characterized by having a threaded portion for screw insertion.

【Example】 1 to 6 are diagrams showing one embodiment of the present invention. Figure 1 is a front view of the present invention, Figure 2 is a right side view, Figure 3 is a perspective view, and Figure 4 is a deck plate. A front view showing the state before the installation of the seat to the reinforcing rib is completed, and Figure 5 shows the state after the installation is completed. FIG. 6 is a partially cutaway front view showing a threaded portion for inserting a hanging bolt.

[0006] In each figure, 1 is the main body of the hanging fitting, and the required metal plate (iron, steel plate, aluminum plate) , other appropriate alloy plates) or hard plastic plates, etc., and the upper part It has a pair of reinforcing rib locking parts 2, 2 made of elastic pieces of the required length and width. Also, is the required height to attach the hanging bolt 3 to the lower hanging bolt installation part? A rising wall 4 for thread cutting is formed, and a hanging bolt is attached to the rising wall 4 for thread cutting. It is provided with a threaded portion 4a for screw insertion. Further, the reinforcing rib locking portions 2, 2 are Above the hanging bolts 3, they are bent inward at a required angle to form a crossed state. and the side surface 2a of one locking part 2, and the inner edge 2a of each locking part 2 on the other side. The side surface 2d of the connecting piece portion 2c having the required width for integrally connecting the hanging bolts 3 It is placed on top of the upper end extension line Y. The shape of the reinforcing rib locking parts 2, 2 is as follows: It can be made arbitrarily according to the shape of the reinforcing ribs B of the deck plate A. 5 is Lower side nut for tightening and fixing the hanging bolt 3, 3a is the upper end of the hanging bolt 3 It is.

[0007] Next, the effect will be explained. When attaching deck plate A to reinforcing rib B First, lock the reinforcing rib locking parts 2, 2 of the hanging fitting main body 1 as shown in FIG. Then, when the hanging bolt 3 is rotated in the upward direction, the upper end extension line of the hanging bolt 3 is Side surface 2a of one reinforcing rib locking portion 2 located on Y and the other reinforcing rib locking portion The side surface 2d of the connecting piece 2c of No. 2 is pressed by the upper end 3a of the hanging bolt 3, Against the spring force, the respective reinforcing rib locking portions 2, 2 change to their respective upright positions, and the front The gripping force of the deck plate A to the reinforcing rib B by the reinforcing rib locking parts 2, 2 is strong. As shown in FIG. 5, the hanging fitting main body 1 can be securely attached.

[0008] In addition, although this example describes installation to a deck plate, It goes without saying that it can be used for things other than that.

[0009]

[Effect of the idea]

According to this invention, a pair of reinforcing rib locking parts made of elastic pieces are attached to the upper part, and suspended to the lower part. In the deck plate hanging fittings each provided with a bolt, each of the pair of reinforcing ribs is Bend the locking parts inwardly at the required angle above the hanging bolt attachment part. Then, the side surface of one of the locking parts in the crossed state is crossed, and each locking part of the other side is The side surface of the connecting piece of the stop portion faces the extension line of the upper end of the hanging bolt, and A stand-up for thread cutting of the required height is installed at the mounting part of the hanging bolt of the hanging bracket for the plate. and a threaded portion for inserting a hanging bolt is provided on the rising wall for thread cutting. Therefore, to install the hanging bracket, simply rotate the hanging bolt, and the pair of Each reinforcing rib locking part can be operated on the left and right sides at the same time, and evenly on the left and right sides. This makes it much easier to handle than conventional products, making installation easier. It can be done quickly and can greatly improve work efficiency even with a small number of people. In addition to this, the structure of the hanging bracket itself is simple, and installation of the hanging bolt is easy. Unlike conventional products, it does not require an upper nut, making it lighter in weight. Both have a small number of parts, save on materials, have great economic effects, and can be supplied at low cost. Of the pair of reinforcing rib locking parts, the bifurcated reinforcing rib locking part is integrally constructed with a connecting piece. Therefore, it has various effects such as being stronger in terms of strength.
