Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hanging metal fitting which is attached to a flange portion of a shaped steel such as so-called H steel / angle and used for suspending various equipments and objects such as piping and wiring.

[0002]

[Prior art]

 As shown in FIG. 3, in the conventional hanging metal fitting, the metal fitting body A is engaged with the flange B of the shaped steel and fixed with the bolt C. To suspend an object, the metal fitting body A is formed on the bottom plate D of the metal fitting body A. A bolt F for suspension is inserted from the lower side into the bolt hole E which is formed, and the nut G is pressed by a fingertip to stop the rotation and then the bolt F is rotated and attached (see Japanese Utility Model Publication No. 50-124597). ).

[0003]

[Problems to be solved by the device]

 In the conventional product as described above, the mounting of the bolt E is a two-handed work, which is not only complicated and dangerous, but also the nut hole E is circular and the insertion position of the bolt F is fixed. Depending on the position of the article to be lowered, the bolt F becomes not vertical but oblique as shown by the phantom line in FIG. 3, which increases the load bearing on the bolt F, which may cause an undesirable situation.

In order to prevent the occurrence of the above situation, the bolt hole E is made a long hole instead of a circular shape so that the bolt tightening position can be adjusted.

However, only by making the bolt hole E a long hole, the insertion position of the bolt F and the position of the nut do not correspond, and it is not easy to attach the nut. In particular, most of the work to attach the hanging metal fittings is done at a high place using a stepladder. The work to adjust the position is dangerous and the workability is very poor, so the current situation is that the construction cost rises due to the rise in personnel costs.

In view of the above, the present invention aims to clarify a hanging metal fitting that can easily perform the work of attaching the bolt F even by one-handed operation and can improve the work efficiency. is there.

[0007]

[Means for Solving the Problems]

 The hanging metal fitting according to the present invention has a structure in which a metal plate is bent into a short rectangular pipe shape to form a ceiling plate, both side plates, and a bottom plate, and is further attached to a flange of a shaped steel by tightening bolts attached to the bottom plate. In the hanging metal fitting to be used, a long hole for passing a bolt for hanging an object is formed in the bottom plate, a housing is formed so as to surround the long hole, and a nut corresponding to the bolt is arranged in the housing. In addition, the nut is slidable in the housing along the elongated hole.

[0008]

[Specific configuration of device]

 Next, a specific configuration of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, a hanging metal fitting 10 according to the present invention is of the same kind as the conventional hanging metal fitting shown in FIG. 3 in terms of basic structure, and is composed of a ceiling plate 11, side plates 12 and 13, and a bottom plate 14. In some embodiments, the side plates 12 and 13 are partially cut away to form the pressure-stopping piece 15, and the pressure-stopping piece 15 is attached to the shaped steel flange by the bolt 16.

The characteristic feature of the hanging fitting 10 of the present invention is that the housing 18 is fixed to the upper portion of the elongated hole 17 formed in the bottom plate 14, and the nut 19 is accommodated in the housing 18. Is. The nut 19 is slidable in the housing 18 along the long hole 17, but is not rotatable.

Since the hanging metal fitting 10 of the present invention is configured as described above, it can be firmly attached by inserting the notch of the side plate 14 into the flange of the shaped steel and tightening the bolt 16. To suspend an object, insert the bolt 20 into the housing 18 from the lower side of the elongated hole 17, rotate the end while pressing the tip against the nut 19, and the nut 19 can be attached without pressing it with your fingertips. The attachment position of 20 can be adjusted by simply moving it horizontally along the long hole 17.

The housing 18 only needs to be covered with a box-shaped structure whose one surface is in an open state so as to cover the periphery of the elongated hole 17. This housing 18 is a mode in which a metal plate is pressed to be welded to the upper surface of the bottom plate 14, a mode in which it is bonded using an adhesive, a mode in which a part of the lower end is fitted into an engagement hole formed in the bottom plate 14, etc. There are various modes. The housing 18 does not necessarily have to be made of metal.

In order to have a structure in which the nut 19 is housed in the housing 18 and can move along the elongated hole 17 but does not rotate, in addition to a mode in which the width of the housing 18 is matched with the width of the nut 19 to prevent rotation, A mode is adopted in which the width of the side plates 12 and 13 of the hanging metal fitting 10 is designed to be narrow, and the side surface of the nut 19 is brought into contact with the side surface of the hanging metal fitting 12 to prevent rotation. In the latter embodiment, the housing 18 may be a holding plate having a U-shaped cross section instead of the box-shaped holding plate.

[0014]

[Effect of device]

 Since the hanging metal fitting 10 of the present invention is constructed as described above, it can be attached to the bolt 20 without pressing the nut 19 with a finger, and the attachment position is adjusted along the elongated hole 17 for any reason. Since these tasks can be performed by one-handed operation, the risk is low even when working on a stepladder, and the work efficiency is extremely high, so that the above-mentioned purpose can be achieved.
