の原因の一つになることもあった。When mounting a hole-in anchor after placing concrete, noise, vibration, dust and the like are generated because the anchor penetrates through the deck plate and is driven into the concrete. Therefore, it was necessary to take an unreasonable posture where the physical strength was exhausted, and the work of installing the hole-in anchor was extremely difficult. In addition, there are places where installation work cannot be performed unless holidays due to noise, dust, and the like, which may be one of the causes of extension of the construction period.

It was necessary to replace the anchor. When the position of the duct is changed, a large number of new hole-in anchors must be hit particularly, and there are many painful operations such as removing the duct.

He had to work hard in his posture. Therefore, an object of the present invention is to eliminate the necessity of previously installing a pipe hanging metal fitting on a deck plate or hitting a hole-in anchor, and furthermore, there is almost no generation of noise or dust in the mounting work of the hanging metal fitting. ,
An object of the present invention is to provide a method of suspending and supporting a pipeline, which is excellent in installation and hardly performs an installation operation in an unreasonable posture. In addition, a magnetic circuit was devised so that a strong attraction force to a to-be-adsorbed object having ferromagnetism would be strong, and no displacement of the attraction surface would occur. Note that the absolute value of the attraction force refers to the force when the magnetic suspension device used in the present invention that is attracted to an iron plate or the like is separated from the attraction surface by a perpendicular force.

できる。A magnetic suspension device used in the method of suspending and supporting a pipeline according to the present invention includes a cup yoke whose opening side is attracted to an object to be attracted, and a permanent magnet having one magnetic pole fixed in the cup yoke. It is preferable to use at least a magnetic attraction member and a suspender attached to the cup yoke, wherein the other magnetic pole of the permanent magnet and the magnetic pole of the cup yoke are attracted to the object to be attracted. For example, when attaching a duct, etc., it is only magnetically attracted to an arbitrary place on the deck plate (for example, made of iron plate), so there is no work such as screwing the hanging bracket into the conventional hole-in anchor. The work becomes very simple, and there is almost no generation of noise and dust, and the workability of the installation is very good. In addition, if a cup yoke is used in which the opening side adsorbs to the object to be attracted, a line of magnetic force from the permanent magnet passes through the object to be attracted (for example, a deck plate or the like) and returns to the magnetic attraction member again through the opening. Therefore, the leakage of magnetic flux is very small.
For example, in a conventional magnetic suspension device, a space between a permanent magnet and an object to be attracted is simply covered with a yoke. For this reason, the magnetic force lines do not reach the object to be attracted through the yoke along the periphery of the magnet, and the magnetic flux is short-circuited, so that the attracting force is reduced. According to the present invention, it is possible to perform a good hanging support without causing a decrease in the attraction force as described above.
Also, as shown in FIG. 1, it is preferable to separate the side surface of the permanent magnet from the cup yoke, because the short circuit of the magnetic flux at this location can be reduced. Further, when the permanent magnet is formed so as not to protrude from the end face of the opening of the cup yoke, only the cup yoke serves as the object to be attracted, and damage to the permanent magnet can be prevented.

することができる。In the magnetic suspension device described above, a magnetic cover is disposed on the other magnetic pole side of the permanent magnet, and the cover is connected to the cup yoke via a non-magnetic member. In addition, the non-magnetic material suppresses the leakage magnetic flux, and the magnetic material lid with high magnetic permeability focuses the lines of magnetic force from the permanent magnets in the attracting direction, so that the attracting force becomes larger. It has an excellent feature that the permanent magnet is protected from the above. In addition, since the attached hanging member is arranged on the bottom surface of the cup yoke, and a hanging member having a hooking member that fits into a recess formed in the cup yoke projects outside the cup yoke, it is practical. It is. Further, it is possible to adopt a configuration in which a connection member having a threaded inner surface is fixed or screwed to a tip of a suspension member protruding outside the cup yoke. It is practical to form the cup yoke by drawing or punching. In addition, the hanging device is provided with a fixing device for fixing the pipeline after gripping and laying the pipeline. In addition, by disposing a plurality of permanent magnets in the cup yoke and arranging the plurality of permanent magnets next to each other on the side facing the object to be attracted so that their magnetic poles are different from each other, the attraction force is reduced. Can be even more powerful.

If the hanging member is provided with a fixing member for holding and laying the conduit after the hanging member, the hanging member is swingable, so that the magnetic attraction member is hardly subjected to a peeling moment.

At least one of a hanging member attached thereto, wherein the other magnetic pole of the permanent magnet and the magnetic pole of the cup yoke are attracted to face the object to be attracted, and a pipeline is provided at an outer bottom of the magnetic attracting member. If one end of the hanging tool for holding the hook is stopped and the other end of the hanging tool is attached to the outer bottom of another magnetic attraction member, the hanging tool may be formed of a wire or formed of a band-shaped member. Then, it becomes flexible, and the workability of installing the pipeline, the vibration resistance and the like are improved.

を吊り下げ支持すれば容易に施行できる。Since the magnetic suspension device used in the present invention has a flat shape of the magnetic attracting member, it is installed on the flat magnetic attracting member which is attracted to the to-be-adsorbed object when suspending a duct such as a duct. There is almost no possibility that the magnetic attraction member will come off due to the collision of the pipeline or the worker's clothes, etc., which will significantly improve the installation workability of the pipeline. It has. This will be described with reference to FIG. In FIG. 3, the outer diameter of the cup yoke 12 'is D, and the height is H. The outer diameter of the permanent magnet 11 is d, and the thickness is t.
The flat ratio of the flat magnetic attraction member 10 provided in the magnetic suspension device 110 is H / D = 0.30, and the flat ratio of the corresponding permanent magnet is t / d = 0.23. The magnetic attraction member provided in the magnetic suspension device has H / D = 0.10 to 0.80, and furthermore, 0.2
It is preferable to set it to 0 to 0.70. If it is less than 0.10, it is difficult to obtain a sufficient adsorption force, and if it exceeds 0.80, the flatness gradually disappears and the above-mentioned practicality is impaired. Further, when H / D is specified in the above range, as described above, the magnetically attracted member that is attracted is as follows.
For example, a peeling force (hereinafter, referred to as a shearing force) in the illustrated A-direction or B-direction other than the pulling force perpendicular to the suction surface due to the collision of the pipeline or the hooking of clothes or the like is prevented. . It has been empirically found that the shear force separates the magnetic attraction member from the object to be attracted with a weaker force than the vertical pulling force. For example, with respect to the suction surface, at a shear force in the direction of 45 °, the suction force is about 50% of that in the case of a vertical tensile force, and about 20% in the case of a parallel shear force.
%. Therefore, the usefulness of the magnetic suspension device provided with the flat magnetic attracting member to which the shearing force is hardly applied is enormous, and the suspension can be easily implemented by suspending and supporting the pipeline using the magnetic suspension device.

One permanent magnet is magnetized in two poles in the cup yoke 12, and two magnetic poles 71, 7 having different magnetizing directions are provided on the attraction surface side.
2 are formed and arranged to increase the magnetic attraction force of the magnetic suspension device 150. The permanent magnet disposed on the inner bottom of the cup yoke 12 is replaced with an epoxy adhesive 19.
Fixed. Further, a ball 17 and a stranded wire 18 were attached to the lower bottom of the cup yoke 12 in the same configuration as in FIG. In the split-pole type magnetic circuit, even when the magnetic flux is saturated, a stronger attraction force can be obtained by dividing the magnetic poles even with the same magnet area. As a split-pole type magnetic circuit, FIG. 7 shows a configuration example of two-pole magnetization using one permanent magnet. However, multi-pole magnetization of three or more poles may be performed. For example, FIG. As shown in FIG. 8B, a configuration in which a large number of magnetic poles are alternately arranged on the attracting side such that adjacent magnetic poles are different may be employed. When it is necessary to increase the magnetic force, that is, the attracting force, it is better to arrange more magnetic poles. Instead of multipolar magnetization, a large number of parallel magnetized permanent magnets are manufactured, and the arrangement of one permanent magnet per magnetic pole is used in FIGS. 8 (a) and 8 (b).
