Description

[Detailed description of the invention] 1. Industrial application field The equipment suspension bracket of the invention, which can be mounted in various ways, can be used to hang equipment such as electric clocks and speakers on horizontal structures such as beams and girders of station platform sheds. When installing a type of equipment in a suspended manner, it is intended to be installed on the horizontal structure and via this.

(2) Conventional technology and problems Currently, when installing an electric clock or other appliance in a suspended manner on the H-shaped steel of a sloping structure on a station platform roof, generally the width of the H-shaped steel is much larger than the width of the H-shaped steel. A wide steel plate is shaped like this when viewed from the side, with the slopes of the left and right sides matching the slopes of the H-shaped steel, and an electric clock or other object is attached to the horizontal part of the center in a suspended manner. To install the H-shaped steel frame, drill a bolt hole in the wide part of the left and right sloping parts, pass the U-shaped bolt hung on the H-shaped steel through it, and tighten it with a nut. The above method involves actual measurement, design, and manufacturing one by one, and errors occur in the process, making it impossible to install the device vertically, or the bolt hole being misaligned and not tightly attached to the U-shaped bolt H-shaped steel. There are disadvantages such as the occurrence of

(3) Actions and effects of the present invention Examples of the present invention will be described below.

FIG. 1 is a side view showing a state in which the instrument suspension fitting of the present invention is attached to the H-shaped steel 9 of an inclined structure, and the instrument is attached in a suspended manner. Base metal fittings 1
is attached to the mounting bracket 3 by means of a long bolt 7 with an inclined H-beam 9 interposed therebetween, but the suspension bracket 2 can be adjusted to any suspension angle using the coupling bolt 6 as the rotation axis. Concentric circles 1 to 4 of base metal fitting 1
is always on the center point of the angle fixing hole 2-2 of the suspension fitting 2. Therefore, at any suspension angle position of the suspension fitting 2, bolt holes are drilled on the concentric circles 1 to 4 corresponding to the center point of the angle fixing hole 2-2 at that point, and tightened with the angle fixing bolt 8. If so, it will be fixed in that position.

Since the connecting bolts 6 that are tightened in the suspension bolt holes 1-1 and 2-1 have the property of rotating shafts, they have little effect on completely fixing the angle of the suspension fittings 2. Therefore, in addition to the connecting bolts 6, Angle fixing bolt 8
It has two locations and has a fixing function that supports it at three points.

FIG. 2 is a front view of the suspension fitting of the present invention attached to the horizontal H-beam 9.

The base metal fitting 1 and the mounting metal fitting 3 are installed vertically with the H-shaped steel sandwiched between them, and an inclined metal fitting 4 and an inclined washer 5 are attached to each of them, and a long bolt 7
If the long bolt 7 is brought into close contact with the H-shaped steel and the nut is tightened, the long bolt 7 will be firmly attached to the H-shaped steel and will not move laterally.

That is, the stopper pieces 4 to 1 of the inclined metal fitting 4 are
The inclined metal fittings 4 are placed in the respective stopper holes 1 to 2 and 3 to 1 of the base metal fitting 1 and the mounting metal fitting 3.
is fixed, whereas the inclined washer 5
In this case, the thick pieces 5 to 2 are held in the direction toward the center point by the stopper pieces 5 to 1 across the inclined side surfaces of the inclined metal fitting 4, but are movable in the direction toward the center point. It's summery.

In this state, when the nut of the long bolt 7 is tightened, a sliding force is applied to the inclined washer 5 on the inclined surface of the inclined metal fitting 4 in the direction of the lower center point of the inclined surface, so that the long bolt 7 is also tightened at the same time. Move in the direction of H-shaped steel 9. Due to this action, the two corresponding long bolts 7 are attached with the H-shaped steel 9 firmly sandwiched between them.

Also, the reason why the thick pieces 5 to 2 and the thin pieces 5 to 3 of the inclined washer 5 are inclined is to correspond to the inclined surface of the inclined metal fitting 4, and at the same time, the head of the long bolt 9 is This is to keep the touching part level.

When the long bolt 7 is passed through the horizontally long bolt holes 1 to 3 of the base metal fitting 1, if the position is the outermost one, it will be the widest H-shaped steel, and if it is the closest to the center point, it will be Can be installed on the narrowest H-shaped steel. That is, in the instrument suspension fitting of the present invention, the H-shaped steel of the structure to be suspended has a certain width, thereby expanding its range of use.

The horizontally long bolt holes 3 to 2, 4 to 2 of the mounting fitting 3 and the inclined metal fitting 4 have functions corresponding to the functions of the horizontally long bolt holes 1 to 3 of the base metal fitting 1.

In Fig. 1, if the vertical part of the base metal fitting 1 is slightly lengthened and the suspension bolt holes 1 to 1 are positioned slightly apart from the lower side of the H-beam 9, the inclination of the H-beam 9 can be adjusted from horizontal to vertical. The suspension fittings 2 can also be attached at any angle.

In Figure 2, the instrument suspension fittings are installed parallel to the H-beam 9, but if the cross section of the H-beam 9 is inclined, the inclination can be accommodated by attaching the instrument suspension fittings at right angles. The device can be mounted suspended at any angle.

In FIG. 1, an instrument suspension tube is attached, but this may be done in any suitable manner depending on the instrument to be attached.

Further, by drilling horizontally long angle fixing holes at appropriate positions on the concentric circles of the base metal fitting 1, the work of drilling the angle fixing holes at the time of installation can be omitted.

FIG. 3 is an exploded perspective view of the instrument suspension fitting of the present invention. The H-shaped steel 9 is moved in the direction of the arrow and is placed on top of the base fitting 1. The respective parts are assembled in the direction of the arrow and a long piece is assembled. When assembled using the bolt 7, the coupling bolt 6, and the angle fixing bolt 8, the state shown in FIGS. 1 and 2 will be obtained.

If a fully threaded bolt is used instead of the long bolt 7, a bolt with a length corresponding to the height of the H-shaped steel 9 can be easily obtained.

As explained above, by standardizing several sizes of the instrument suspension fittings of the present invention in advance,
In most cases, by actually measuring only the width of the H-shaped steel 9 of the structure to be suspended, the device can be easily and securely mounted at any suspension angle and with the H-shaped steel strongly sandwiched.

Therefore, as in the conventional method, the inclination angle of each H-shaped steel 9 and its installation method must be measured, which is dangerous.
This eliminates the need for design and manufacturing work such as mold shapes, and at the same time eliminates problems caused by errors in the actual measurement, design, and manufacturing processes.
