Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention is to prevent suspension members such as suspension bolts that suspend cable racks, ducts, etc. from steadying. Moreover, the present invention relates to a steady rest device for a hanging rod member that can be installed as an afterthought on an existing hanging rod member.

(Conventional technology) Conventionally, cable racks, air conditioning ducts, and other appliances were installed in buildings, factories, and other architectural structures using ceiling slabs,
When suspended from a steel beam, they are supported by suspension rod members such as suspension bolts. At that time, if the hanging interval was relatively long, it would swing from side to side, which could be dangerous during and even after construction.

For this reason, the present applicant proposed a shaking prevention device for wiring devices as published in Japanese Utility Model Publication No. 11557/1983, which can be installed at the time of construction to prevent shaking. This anti-vibration device supports a support fitting that is inserted through and screwed into a hanging rod member for suspending instruments from an obliquely upper side, which is different from the hanging direction of the hanging rod member. In other words, it is configured to be supported obliquely from above in two directions.

(Problems to be Solved by the Invention) The conventional vibration prevention device described above has various drawbacks because it uses a support fitting that is inserted through the hanging rod member and fastened with screws.

For example, when installing such a shaking prevention device, as a result of the visual inspection carried out after the equipment has been suspended, the need for steady resting measures may be indicated to ensure safety. This would be difficult if the project was to be carried out as additional construction work. In other words, in order to insert the support metal fittings into the hanging rod member, it is necessary to first remove the connecting part between the hanging rod member and the equipment, screw the equipment, and then reinstall it, which reduces the construction work. It was necessary to start over again.

Therefore, this idea allows for easy installation without the need to remove the hanging rod members from the support fittings, not only during the suspension construction using the hanging rod members, but also for retrofitting after the suspension construction is completed. An object of the present invention is to provide a steady rest device for a hanging rod member that can perform steady rest.

[Structure of the invention] (Means for solving the problem) In order to achieve the above-mentioned purpose, this invention includes a fixing member that is attached from the side of the existing hanging rod member, and a screw attached to this fixing member. It consists of a connecting member that is fixedly connected and extends obliquely upward, and a support rod that is suspended from an obliquely upward direction that is different from the hanging direction of the hanging rod member and is connected to the connecting member.

(Function) In the device for steadying a hanging rod member according to this invention, the fixing member is fitted from the side of the existing hanging rod member at a predetermined position and fixed together with the connecting member by screws.

Then, the support piece of this connection member is connected to a support rod member from diagonally above, which is different from the hanging position of the suspension rod member.

Then, the suspension rod member and the support rod member support at two points from different directions, and shaking is prevented.

Alternatively, connecting members and support rods may be connected and arranged on both sides of the fixing member in a substantially symmetrical structure to support the fixing member from two directions.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

Reference numeral B shown in the figure is a hanging rod member such as a hanging bolt suspended from a ceiling slab, steel beam, etc., and a cable rack, air conditioning duct, and other appliances T are supported and connected to this hanging rod member B. There is. A well-known support fitting S is used for the support and connection, and a detailed explanation thereof will be omitted.

This invented steady rest device is installed on the hanging rod member B that suspends the instruments T in this way.

That is, the fixing member 1 that is attached from the side of the existing hanging rod member B, the connecting member 10 that is screwed and connected to this fixing member 1 and extends obliquely upward, and the hanging direction of the hanging rod member B. The supporting rod members 20 are connected to the connecting member 10 by hanging down from different diagonal upper sides.

The fixing member 1 is formed into a substantially groove-shaped cross section, with upper and lower wing pieces 3 having fitting notches 2 cut therein, which are fitted into the hanging rod member B from the side, bent and connected in a row so as to face each other at the top and bottom of the deep side 4. It is mounted at any position on the hanging rod member B, particularly at a position directly above the support fitting S.

The connecting member 10 is located beside the opening of the fixed member 1 and extends obliquely upward to a connecting piece 12 that is opposed to this and is screwed onto a tightening bolt 11 inserted through the inner bottom side 4. It consists of support pieces 13 that are approximately L-shaped on the sides. The angle at which the support piece 13 is connected diagonally upward to the connection piece 12 corresponds to the two-point support interval for steadying, that is, the support rod member 20 relative to the suspension rod member B.
This corresponds approximately to the support angle between the support position and the support position.

Although the tightening bolts 11 are inserted into through holes drilled in the bottom side 4 of the fixing member 1 and the connecting piece 12, and are fastened with nuts, the tightening bolts 11 cannot be inserted directly into the connecting pieces 12. You can also screw it in.

The support rod material 20 has its lower end inserted into the L-shaped portion of the support piece 13 of the connecting member 10 and is screwed therethrough. ing.

Further, in FIG. 3, a connecting member 10 and a supporting rod member 20 are connected and arranged in a substantially symmetrical structure on both sides of the fixed member 1 in order to prevent the hanging rod member B from steadying from two directions. At this time, the other connecting member 10 is screwed to the tightening bolt 11 while in contact with the outer surface of the deep side 4 of the fixing member 1. By doing this, the structure of the fixing member 1 can be made different. It is convenient as there is no need to tighten it.

This idea is structured as described above, and the first
As shown in the figure, the fixing member 1 is fitted from the side of the existing hanging rod member B at a predetermined position, fixed with screws together with the connecting member 10, and the supporting piece 13 of the connecting member 10 is attached to the hanging rod member B. It is connected to the support rod member 20 from diagonally above at a different position.

Alternatively, as shown in FIG. 3, a connecting member 10 and a support rod 20 may be connected and arranged on both sides of the fixing member 1 in a substantially symmetrical structure to support it from two directions.

[Effects of the invention] Therefore, the steady rest can be applied to the existing hanging rod member B by retrofitting, and there is no need to carry out the troublesome re-installation as in the past, and work efficiency is greatly improved. to improve.

That is, this includes a fixing member 1 that is attached from the side of the existing hanging rod member B, and a connecting member 10 that is screwed and connected to this fixing member 1 and extends obliquely upward.
and a support rod member 2 connected to the connecting member 10 by hanging from an obliquely upper direction different from the hanging direction of the hanging rod member B.
0, and moreover, it is easy to stabilize not only from one direction but also from two directions.

As explained above, according to this invention, it is not necessary to remove the hanging rod member from the support fitting, not only during the suspension construction using the hanging rod member, but also even after the suspension construction is completed. It can be easily installed and provides excellent effects such as reliable steady rest.
