Description

[Detailed Description of the Invention] The present invention relates to a hanging fitting used when suspending an object from a fixed rod-shaped body.

Examples of the object to be suspended include various types of ceiling equipment and ceiling structures using the semicon shield method.

For example, in this method of constructing a ceiling structure, long ceiling panels are placed on support bars with flanges arranged in parallel, and upper and lower flanges are attached to adjacent ceiling panels in grooves formed on the long sides of the panels. The connection is made by fitting the lower flange of the connection bar.

In recent years, there has been a tendency to use longer ceiling panels than before in ceiling structures based on the above-mentioned construction method due to the need for modules and the like.

However, the ceiling structure described above cannot prevent the ceiling board from bending due to its own weight, making it impossible to use a long ceiling board.

In addition, openings for ceiling equipment such as lighting equipment are provided on the ceiling surface, and reinforcing materials are arranged around the openings to connect and fix rod-shaped objects such as field fences and the reinforcing materials, or ceiling equipment In some cases, the product may be suspended from a rod-shaped body, and in this case, conventionally, it was fixed by welding with metal fittings or by using special fixing metal fittings. However, the former method has the drawback of poor workability, and the latter method requires metal fittings of various sizes depending on the construction site, resulting in poor productivity.

The present invention was devised in view of the above-mentioned drawbacks of the conventional art, and its purpose is to provide a hanging fixture that is easy to install and has a wide range of versatility.

Next, the present invention will be explained with reference to the drawings which are one embodiment.

In FIG. 1, 1 is a hanging fitting according to the present invention, which includes a clamping fitting 2, a hanging bolt hole 3, and a nut 4.
It consists of

The clamping fitting 2 has a U for engagement with the hanging bolt hole 3.
It consists of a flat clamping part 6 with a notch 5 in the shape of a letter, and a locking part 7 which is connected to the clamping part 6 and has a substantially inverted L-shape in cross section, and the two pieces make up one set.

The hanging bolt hole 3 is approximately J-shaped, and a screw 8 is formed in the upper half of the straight part, and the object suspended in this part falls off at the end of the curved part. In order to prevent this, a bent portion 9 is formed which is slightly bent inward.

Next, an example of applying the present invention to a ceiling structure is shown in the second to
This will be explained with reference to FIG.

In the figure, reference numeral 10 denotes a long support member, which is suspended from the lower surface of the roof frame or the floor slab on the upper floor through hanging bolt holes 11 and hanging tools 12.

Reference numeral 13 denotes an inverted T-shaped support bar, which has a flange 14 at its lower part, and is suspended from the support member 10 in a direction perpendicular thereto and at a predetermined height.

15 is an L-shaped peripheral edge with a flange 16 at the bottom.
It is attached to the wall parallel to and at the same height as the support bar 13.

Reference numeral 17 denotes a ceiling plate, which is made of mineral fiber or the like, and is long and rectangular. The short side 18a is placed on the flange 14 or the flange 16, and a groove 19 is provided on the side surface of the long side 18b. The lower flange 21a of the shaped connecting bar 20 is fitted into the connecting bar 20, and the connecting bar 20 is connected in the short side direction thereof.

Reference numeral 22 denotes a long rod-shaped body, which is suspended from the support member 10 by the hanging fitting 1 in a direction orthogonal thereto, and has a chevron-shaped clip 2 having a hook portion at the bottom.
The ceiling plate 17 is held by fixing the H-shaped connecting bar 20 through the holes 3 and 3. Here, for the hanging fitting 1, while attaching the clamping fitting 2 to the support member 10, hooking the elongated rod-shaped body 22 to the hanging bolt 3, and inserting the screw 8 into the notch 5,
The support member 10 and the elongated rod-shaped body 22 are fixed by crimping the two clamping fittings 2 with the nuts 4.

In addition, like the clamping fitting 2' shown in Fig. 6,
By providing a protrusion 24 formed by press working or the like on the end of the locking portion 7', it is possible to prevent the clamping fitting 2' from coming off from the support member 10 even if the nut 4 is slightly loosened. By bending the end of the notch 5' as shown by the broken line, the nut 4 can be prevented from falling off, making it safe not only during adjustment work during construction but also after completion.

Further, as in the clamping fitting 2'' shown in FIG. 7, the shape of the locking portion 7'' may be made approximately J-shaped in cross section in accordance with the shape of the member to be engaged.

As is clear from the above description, according to the present invention, two members are connected by tightening the clamping fitting and the hanging bolt with nuts. For this reason, when the present invention is applied to a ceiling structure using the earlier semi-concealed construction method, for example, a clamping metal fitting is attached to the support member, while an H-shaped connecting bar is suspended from the hanging bolt portion to hold the ceiling board. I can do it. Therefore, even if the ceiling board becomes larger, by appropriately increasing the number of hanging fittings attached to the support member, the ceiling board can be prevented from sagging due to its own weight, and a flat ceiling can be constructed.
It is possible to improve the appearance.

Furthermore, since the hanging fitting can be easily attached by simply tightening the clamping fitting with a nut, it is easy to adjust the mounting position and the hanging height, which has the effect of shortening the construction period.

It should be noted that the present invention is of course applicable not only to the ceiling structure but also to other hanging structures having rod-shaped bodies.
