Mounted and supported. Therefore, between the suspension rod member and the support member, it is necessary to arrange the connector at the end in the length direction of the support member, so the length of the support member should be longer than the gap between the suspension rod members. This means that it cannot be installed when the number of wires to be supported increases and the length of the support member increases. Furthermore, it is very troublesome to cut the supporting members each time to match the spacing between the hanging rod members.

Therefore, this invention was devised to solve the above-mentioned drawbacks of the conventional device, and even if the support member is sufficiently long, it can be installed without being restricted by the hanging spacing of the hanging rod members. It is an object of the present invention to provide a support device which can be supported by more than one hanging rod member and is suitable for support when a load is large.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in this invention, the upper and lower wing pieces, each having a fitting notch that fits externally into the hanging rod member, are made to face each other above and below the inner bottom piece. It has a support member with a substantially groove-shaped cross section formed by continuous bending, a support member made of lip channel steel disposed between the hanging rod members, a clamping bolt and a nut, and a support member on the outer surface of the support member at the tip. A clamping piece whose back surface is pressed against the hanging rod member by screwing a tightening screw inserted into the deep bottom piece of the support into a clamping piece that contacts the support member in the width direction by vertically forming a contacting presser piece. The supporting member is connected and fixed to the hanging rod member from the side.

(Function) In the support device using the hanging rod member according to this invention, supports and connectors are assembled so as to face each other at a predetermined height to accommodate ducts, cable racks, large quantities of piping, etc. that are planned to be added. They may be set together on the hanging rod member, and a supporting member may be arranged in a horizontal manner between the connecting members.

That is, the coupling tool is attached from the side of the support member by clamping the lip portion of the support member with the clamp bolt, nut, and clamp piece.

In this state, the support and the stopper piece are screwed together with tightening screws so that the suspension rod member is sandwiched at a predetermined position of the suspension rod member, and the suspension rod member is clamped to connect and support the suspension rod member.

At this time, the support member itself is supported by the suspension rod member by the supports and connectors that are connected and supported from the sides, and is not subject to any restrictions on the spacing between the suspension rod members. The connection position can be arbitrary, and the length can be set as desired, allowing installation in various ways.

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

Reference numeral 1 shown in the figure is a support having a substantially groove-shaped cross section, and is a fitting that fits onto an existing suspension rod member B such as a suspension bolt, round bar, or suspension wire suspended from a ceiling slab, steel beam, etc. The upper and lower wing pieces 4, each having a matching notch 5, are bent and connected to face each other above and below the bottom piece 2. The support 1 itself is obtained by appropriately cutting and bending a rectangular plate material of appropriate thickness, and the fitting notch 5 is provided by cutting a U-shaped notch from the opening edge of the upper and lower wing pieces 4. It has a depth and a width corresponding to the diameter of the hanging rod member B.

Reference numeral 6 denotes a support member made of lip channel steel that is arranged in a suspended manner between the hanging rod members B, and is normally used with the opening, which is the lip portion 7, facing upward, and its overall cross section is as shown in the figure. Not only in the form of
It may be in the form 〓 or 〓.

In order to connect and fix the support member 6 to the suspension member B from the side in cooperation with the support member 1, there is a connector 8 whose side surface is approximately L-shaped.
It has a clamping piece 9 that comes into contact with the support member in the width direction and a pressing piece 14 that comes into contact with the hanging rod member B. The clamping piece 9 is
In order to clamp the lip portion 7 of the support member 6 with screws,
As shown in the figure, it has a clamping bolt 10 and a nut 11, and the clamping piece 9 is attached to the nut 11, which has a planar rectangular or parallelogram shape and is engaged inside the lip part 7 while being inserted into the support member 6. Opened penetration hole 1
By screwing in the clamping bolt 10 inserted through 2, the lip part 7 is strongly clamped and supported between the clamping piece 9 and the nut 11. In addition, as shown in the figure, the clamping piece 9
At the tip, there is a presser piece 1 that comes into contact with the outer surface of the support member 6.
3 is formed vertically.

On the other hand, the pressing piece 14 is provided upright from the clamping piece 9, and a tightening screw 17 inserted through the inner bottom piece 2 of the support 1 is screwed into the pressing piece 14, so that the back surface is pressed against the hanging rod member B. For this reason, screw holes 15 are formed on the left and right sides, into which the tightening screws 17 are inserted, respectively, through the pair of through-holes 3 opened on the left and right sides of the inner bottom piece 2.

In addition, 16 is a reinforcing bead formed in the continuous standing portion of the clamping piece 9 and the pressing piece 14.

(Effects of the invention) This invention is constructed as described above, and when used, it is possible to use existing equipment that is suspended to support various equipment (not shown) such as sanitation, air conditioning, electricity, and disaster prevention equipment. If there is a hanging rod member B, this is effective for utilizing the space.

That is, the support 1 and the connector 8 are combined and set on the suspension rod member B while facing each other at a predetermined height position corresponding to the duct, cable rack, large amount of piping P, etc. that are planned to be added. The support members 6 may be arranged in a horizontal structure between the tools 8. For example, the coupling tool 8 can be attached from the side of the support member 6 by clamping the lip portion 7 of the support member 6 in the width direction of the support member 6 using the clamp bolt 10, nut 11, and clamp piece 9. In this state, the support 1 and the stopper piece 14 are screwed together with the tightening screws 17 so that the suspension rod member B is sandwiched at a predetermined position of the suspension rod member B, and the suspension rod member B is clamped. Connect and support.
After that, the piping P and the like may be placed and set on the support member 6.

Therefore, even with the existing hanging rod members B that support various equipment, if there is space where they can be used at least in pairs, it is possible to install necessary ducts, cable racks, large amounts of piping P, and other additions. It can be installed easily and quickly without being interfered with by existing equipment.

In particular, even if the hanging distance between the hanging rod members B is narrow,
Since the support 1 and the connector 8 support the support member 6 from the sides of the support member 6, even if the support member 6 is sufficiently long, it can be installed. That is, as shown in FIG. 3, although the support member 6 is supported in a state in which one of the hanging rod members B is extended outwardly, as shown in FIG. 4, the load increases and the three The support member 6 may be supported by the plurality of hanging rod members B described above, and installation in any manner is possible. Furthermore, even if the item to be added is heavy, it has a load capacity that can sufficiently support it, and its support stability is high, so it can cope with any expansion plan.

Further, the support 1 itself has a substantially groove-shaped cross section, and is formed by bending and connecting upper and lower wing pieces 4, each having a fitting notch 5 that fits externally into the hanging rod member B, facing each other above and below the bottom piece 2. Therefore, it can be directly attached to the desired position of the hanging rod member B. Moreover, by screwing the tightening screw 17 inserted into the inner bottom piece 2 into the pressure stopper piece 14 of the connector 8, the back surface of the pressure stopper piece 14 and the inner edge of the fitting notch 5 are connected to the hanging rod member B. One side is in planar contact and the other is press-fitted in a biting manner, and at that time, it is sandwiched on both sides, so it can be firmly set, and has excellent load resistance and provides sufficient support even for large-capacity piping P etc. It is possible.

Since the support member 6 on which the piping P and the like are mounted and set is made of lip channel steel, there is no problem with load resistance, and when the support member 6 is connected to the hanging rod member B, the lip portion 7 is clamped by a clamping piece 9 having a clamping bolt 10 and a nut 11 in the connector 8, so that the connection between the support member 6 and the connector 8 is reliable. Further, the support member 6 itself is supported by the hanging rod member B by the supporting tool 1 and the connecting tool 8, which are connected and supported from the sides, and is not subject to any restrictions on the spacing between the hanging rod members B. , it can be set to any length and can be installed in various ways.

The connector 8 is a clamping piece 9 that clamps and connects the support member 6.
In addition, since the side surface is approximately L-shaped and has a press-fitting piece 14 that cooperates with the support member 1 and press-fits the hanging rod member B by screwing it, the supporting member 6 can be held at any position of the hanging rod member B.
can be used without being affected by existing equipment. In addition, since a presser piece 13 is vertically formed at the tip of the clamping piece 9 to abut against the outer surface of the support member 6, the looseness caused during clamping is eliminated and support stability is increased. .
