Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension fitting, and more particularly, to a deck plate, a ceiling iron plate, and the like for hanging various suspended objects disposed in a ceiling of a building, for example, an air-conditioning duct, a pipe for an electric wire, a pipe for a refrigerant, and the like. The present invention relates to a hanging bracket for hanging and supporting a paramagnetic fixed object such as a steel frame for beams.

[0002]

2. Description of the Related Art Conventionally, for example, air-conditioning ducts, electric-wire piping, refrigerant piping, and the like are suspended and supported on a deck plate in a ceiling of a building by, for example, a hole-in-anchor hanging bracket or a deck-plate hanging bracket. Has been used.

[0003] However, in the case of the hole-in anchor hanging bracket, it is necessary to make a hole in the concrete slab through the deck plate and drive the hole-in anchor bolt into the hole with a hammer, which is very time-consuming. There was a disadvantage.

Further, in the case of the deck plate hanging metal, the deck plate hanging metal is used to lock the deck plate hanging metal, so that it cannot be attached to any part other than the deck plate groove. There were drawbacks.

[0005] The applicant of the present invention has paid attention to the fact that the deck plate is made of a paramagnetic material such as a galvanized thin iron plate in order to eliminate the drawbacks of the conventional hanging metal fittings, and reduces the magnetic attraction force of the permanent magnet. We have already proposed a hanging metal fitting that can be fixed to a deck plate by using it and an improved invention thereof (Japanese Patent Application Nos. 7-042241 and 7-139).
No. 812).

Further, the applicant of the present invention provides a hanging metal fitting which can easily increase the fixing force to a fixed object, and can be manufactured efficiently and at low cost by sharing parts. For this purpose, a hanging bracket having a plurality of plate-like permanent magnets, one or more center yokes, and a pair of side yokes has been proposed (Japanese Patent Application No. Hei 7-21416).
No. 4).

[0007]

However, in the above-mentioned conventional hanging metal fittings, one plate-shaped permanent magnet and a pair of side yokes, a plate-shaped permanent magnet group which can only move in the vertical direction only fixedly, and the like. Since it is formed by a group of yokes (a collection of a center yoke and side yokes), if there are irregularities on the surface of a paramagnetic fixed object such as a deck plate, a ceiling iron plate, and a steel frame for beams, a plate-like permanent magnet group (Includes a single plate-shaped permanent magnet) and a gap is formed between the yoke group and the deck plate surface, etc., which may weaken the magnetic attractive force (a desired magnetic attractive force cannot be obtained). The situation arises).

Here, the following reasons are considered as the reason why the unevenness occurs on the deck plate surface or the like. It is not rare that such unevenness occurs. It is common that embossing and ribs are regularly provided on the surface of a flat deck, which is a kind of deck plate (see FIG. 6). Deflection or bending occurs due to the weight of concrete with respect to the deck plate, and unevenness occurs on the deck plate surface. A deck plate, a ceiling iron plate, a steel frame for beams, and the like usually have not only a plane portion but also a curved surface portion.

In view of the above, it is an object of the present invention to separate one or more plate-shaped permanent magnets, one or more center yokes (which may not be present), and two side yokes separately from each other in the vertical direction. Provided is a hanging metal fitting which can flexibly and easily increase a fixing force (fixing force based on a magnetic attraction force) to a fixed object having irregularities by enabling the moving member to move in a vertical direction. It is in.

Another object of the present invention is to form an integrated case for integrating the group of plate-like permanent magnets and the group of yokes with a non-magnetic material while achieving the above object. Weak magnetic attraction at the desired fixed surface due to the case being made of magnetic material (weak magnetic attraction due to leakage of magnetic flux generated by the plate-like permanent magnets into the magnetic material integrated case) ) Can be prevented.

[0011]

A hanging bracket according to the present invention comprises a plurality of plate-like permanent magnets having pin holes, a center yoke interposed between the plate-like permanent magnets and having pin holes, and two end positions. A side yoke in contact with the plate-shaped permanent magnet and having a pin hole, an integrated case integrating the plate-shaped permanent magnet, the center yoke, and the side yoke and having a pin hole; A pin yoke that penetrates the center yoke, the side yoke, and the integrated case and is made of a non-magnetic material; and a vertical direction of pin holes formed in the plate-shaped permanent magnet, the center yoke, and the side yoke. Is larger than the diameter of the cross section of the pin shaft, and the shape of the pin hole formed in the integrated case is adjusted to the cross sectional shape of the pin shaft and the penetration margin (to allow the pin shaft to penetrate and slide. By taking the same into consideration in consideration of a margin length, each of the plurality of plate-like permanent magnets, one or more center yokes, and two side yokes can be individually moved in the vertical direction. The magnetic recording medium is fixed to a fixed object having paramagnetic irregularities by a magnetic attraction force generated by the plate-shaped permanent magnet.

[0012] Further, the hanging bracket of the present invention comprises a plate-shaped permanent magnet having a pin hole, a side yoke having a pin hole in contact with the plate-shaped permanent magnet, the plate-shaped permanent magnet and the side magnet. An integrated case having an integrated yoke and having a pin hole; and a pin shaft made of a non-magnetic material penetrating the plate-shaped permanent magnet, the side yoke, and the integrated case. The length of the pin hole formed in the side yoke in the vertical direction is made larger than the diameter of the cross section of the pin shaft, and the shape of the pin hole formed in the integrated case is set to the cross sectional shape of the pin shaft and the penetration margin. In consideration of the above, the plate-shaped permanent magnet and the two side yokes can be individually moved in the vertical direction, and the magnetic attraction force generated by the plate-shaped permanent magnet can be used. It is also possible, characterized in that it is fixed to the stationary object that may have uneven magnetic.

In a preferred embodiment of the hanging bracket according to the present invention, the integrated case is formed of a non-magnetic material.

(The pin shaft 17 also has a function as a support shaft for allowing the suspension bolt holder 16 to swing freely.)

FIG. 2 shows the shape of the rectangular plate-shaped permanent magnet 11, in particular, a pin hole (pin shaft 1) formed in the rectangular plate-shaped permanent magnet 11.
FIG. 7 is a view showing the shape of a hole through which a hole 7 passes).

The square plate-shaped permanent magnet 11 is formed with a pin hole having a circular shape having a diameter (d 'in the figure) larger than the diameter (d in the figure) of the cross section of the pin shaft 17. . Here, the size of “d′−d” is set to an appropriate size as the individual movable distance of the rectangular plate-shaped permanent magnet 11 in the vertical direction.

The rectangular plate-shaped permanent magnet 11 is formed of a ferromagnetic material such as a ferrite-based, samarium-based, or neodymium-based permanent magnet.

The edge of the rectangular plate-shaped permanent magnet 11 can be chamfered to prevent chipping.

FIG. 3 shows the shape of the side yoke 12 or the center yoke 13 (shown here as a yoke), in particular, a pin hole (a hole through which the pin shaft 17 passes) formed in the yoke.
It is a figure showing the shape of. The yoke has a horizontal diameter that is the same as the cross-sectional diameter of the pin shaft 17 (d in the figure) (same in consideration of the penetration allowance), and is larger than the cross-sectional diameter of the pin shaft 17 in the vertical direction. A pin hole having an elliptical shape (here, a shape in which both upper and lower ends are semicircles and the semicircles are connected by a straight line) having a diameter in the direction (d '' in the figure) is formed. I have. Here, the size of “d ″ −d” is set to an appropriate size as an individual vertical movable distance of the rectangular plate-shaped permanent magnet 11, and generally “d” −d in FIG. '-D'.

The shape of the pin holes formed in the rectangular plate-shaped permanent magnet 11 and the yoke is such that the rectangular plate-shaped permanent magnet 11 and the yoke can be individually moved perpendicularly to the pin shaft 17 by an appropriate distance. Needless to say, the shape is not limited to the shape shown in FIGS. 2 and 3 (including the position of the pin hole).

FIG. 4 is a front view, a side view, a plan view, and a bottom view showing the structure of the integrated case 14. As shown in FIG.

The integrated case 14 has the following structural features. It is formed of a non-magnetic material such as stainless steel. As described above, the reason why the integrated case 14 is formed of the non-magnetic material is because the magnetic flux generated by the plurality of rectangular plate-shaped permanent magnets 11 is leaked (when the integrated case 14 is formed of the magnetic material, This is to prevent the magnetic flux from leaking into the integrated case 14) and strengthen the magnetic attraction force of the plurality of rectangular plate-shaped permanent magnets 11. The diameter of the pin hole formed in the side surface is the same as the diameter of the pin shaft 17 in consideration of the allowance for penetration. A fixing bent piece bent in an L shape from the vertical direction to the horizontal direction is provided. A bolt hole for connection is formed in the fixing bent piece. It is possible to reinforce the fixing force by the magnetic attraction force by connecting the bent piece for fixing with a bolt (connection using the above-mentioned bolt hole) or bonding using an adhesive. However, the presence of the bent piece for fixing is not essential to the present invention. The upper protrusion is a wire hook for enabling the hanging object to be suspended by the integrated case 14 itself.

In order to assemble the suspension fitting 10 of the present embodiment, the following manufacturing steps are employed. First, a square plate-shaped permanent magnet 11, a side yoke 12,
A pin hole having a shape as shown in FIGS. 2 and 3 is formed in the center yoke 13. Here, the formation of the circular pin hole in the rectangular plate-shaped permanent magnet 11 is difficult to make a hole having a shape other than a circle such as an oblong shape in the rectangular plate-shaped permanent magnet 11 which is a ferromagnetic material. to cause. On the other hand, the yoke (the side yoke 12 or the center yoke 13) does not have such difficulty, so that an oval hole suitable for performing only vertical movement is formed. However, the shape of the pin hole is not limited to these shapes, as described above. Next, an integrated case 14 having a shape as shown in FIG. 4 is formed of a non-magnetic material such as stainless steel. Further, the integrated case 14 allows the plurality of rectangular plate-shaped permanent magnets 1 to be formed.
One or two side yokes 12 and one or more center yokes 13 are integrated, and a set of square plate-shaped permanent magnets 11, side yokes 12, and center yokes 13 are individually formed in directions other than the vertical direction. Fixed so that it does not move. At this time, the side yoke 12 and the center yoke 13 are attracted by the magnetic attraction force of the rectangular plate-shaped permanent magnet 11, thereby facilitating the above integration process. Subsequently, the pin shaft 17 penetrates through the rectangular plate-shaped permanent magnet 11, the side yoke 12, the center yoke 13 (including the integrated case 14 itself) and the suspension bolt holder 16 integrated by the integrated case 14, The suspension bolt holder 16 is attached to the integrated case 14. In addition,
The nut 15 is formed on the suspension bolt holder 16 in advance.

The hanging fitting 1 assembled in this manner
At 0, a plurality of (here, four) square plate-shaped permanent magnets 11, two side yokes 12, and one or more (here, three) center yokes 13 are individually vertically It is possible to move in the direction. As a result, even when the hanging metal 10 is fixed to a deck plate having unevenness due to embossing or the like as shown in FIG. , And the center yoke 13 can be individually moved up and down. Therefore, a gap is less likely to be formed between the deck plate surface and the fixed surface of the square plate-shaped permanent magnet 11, the side yoke 12, and the center yoke 13, so that the magnetic attraction force is weakened due to the gap. Can be avoided.

Here, when the suspended object is suspended and supported by using the suspension fitting 10, the suspended supporting force is not only the magnetic attraction force of the rectangular plate-shaped permanent magnet 11, but also the integrated case 1
By using the bent piece for fixing 4, it is also possible to reinforce by connecting with a bolt and bonding with an adhesive.

FIG. 5 is a front sectional view showing a hanging fitting 20 according to a second embodiment of the present invention. Hanging bracket 2 of the present embodiment
0 denotes one rectangular plate-shaped permanent magnet 2 magnetized in the thickness direction.
1, a pair of (two) side yokes 22 made of a metal plate having high magnetic permeability such as iron, and a square plate-shaped permanent magnet 21 and a side yoke 22 are integrated to form a square plate-shaped permanent magnet 21 and a side yoke 12, respectively. , An integrated case 23 for preventing individual movement in directions other than the vertical direction (up-down direction), a suspension bolt holder 25 having a nut 24 for screwing a suspension bolt (not shown), Permanent magnet 21,
A pin shaft 26 made of a non-magnetic material and penetrating through the side yoke 22, the integrated case 23, and the suspension bolt holder 25 (the pin shaft 26 also has a function as a support shaft for the suspension bolt holder 25 to be able to swing freely. The main part is constituted from.

The structure of the hanging bracket 20 of the present embodiment is shown in FIG.
In the hanging metal fittings 10 shown in (a) and (b), it corresponds to a structure in which one square plate-shaped permanent magnet 11 is provided and the center yoke 13 is not present. Therefore, the mode of assembly and use is the same as that of the first embodiment.
Same as 0.

By the way, with respect to each of the above-mentioned embodiments, the following modifications or expansions can be considered.

As described above, the shape of the pin hole is not limited to the shapes shown in FIGS. 2 and 3, and can be changed to another shape.

The shape of the pin hole formed in the side yoke is made the same in consideration of the cross-sectional shape of the pin shaft and the penetration margin, and the square yoke-shaped permanent magnet and the center yoke (the It does not exist in the case of the two embodiments), and the side yoke itself can be integrated.

Instead of the suspension bolt holder 16 or 25 as shown in FIGS. 1A and 1B or FIG. 5,
It is also possible to adopt a holder other than such a suspension bolt holder (a holder having a universal joint or the like).

In addition, it is also possible to suspend the suspended object by the integrated case itself without using a holder such as a suspension bolt holder. In this case, the suspension can be realized by a wire hook or the like shown in FIG.

As a cross-sectional shape of the pin shaft, a shape other than a circle can be adopted. In this case, the shape of the pin holes of the integrated case and the suspension bolt holder is the same in consideration of the cross-sectional shape of the pin shaft and the allowance for penetration, and the shape of the pin holes of the rectangular plate-shaped permanent magnet and the yoke is one or more. The rectangular plate-shaped permanent magnet and the plurality of yokes each have a shape (a shape in which a pin shaft can be loosely fitted) that can individually move up and down.

In each of the above embodiments, the plate-shaped permanent magnet is a rectangular plate-shaped permanent magnet 11 or 21, but the shape of the plate-shaped permanent magnet is not limited to a square.

It is needless to say that the fixed object is not limited to the deck plate, but may be any paramagnetic material such as an iron plate and a steel frame.

[0037]

As described above, according to the hanging bracket of the present invention, one or more plate-shaped permanent magnets having pin holes are provided.
A center yoke interposed between the plate-like permanent magnets and having a pin hole (the center yoke does not exist when there is only one plate-like permanent magnet); A side yoke having holes, the plate-shaped permanent magnet, the center yoke (which may not be present), and an integrated case having the pin holes and integrating the side yoke; the plate-shaped permanent magnet, the center yoke; A pin shaft that penetrates the side yoke and the integrated case, wherein a vertical length of a pin hole formed in the plate-shaped permanent magnet, the center yoke, and the side yoke is determined by the length of the pin shaft. By making the shape of the pin hole formed in the integrated case the same in consideration of the cross-sectional shape and the penetration margin of the pin shaft, one or more of the The permanent magnet, the one or more center yokes (which may not be present), and the two side yokes can be individually moved in the vertical direction, so that a fixed object having irregularities can be removed. , Flexible fixation is possible, the magnetic attraction force can be easily enhanced, the play due to the separation of the suction surface from the fixed object does not occur, and the fixation force due to the magnetic attraction force by the plate-shaped permanent magnet is reduced. It has the effect that it can be used to the fullest.
