Description

[Detailed explanation of the invention] (Field of industrial application) This invention is mainly used when adding various equipment after the construction of buildings, factories, etc.
The present invention relates to a support device using hanging rod members that can utilize the space between a plurality of hanging rod members such as hanging bolts for suspending air conditioning ducts, wiring members, piping, and the like.

(Prior Art) The present applicant has proposed a support device using a hanging rod member in Japanese Utility Model Application Publication No. 60-58983, and has proposed a support device using a hanging rod member, and has improved the existing hanging rods for suspending air conditioning ducts, wiring members, piping, etc. It was shown that by using rod members, it is possible to make effective use of space and add various types of equipment.

This shall be arranged by fitting support members made of lip channel steel between multiple suspension rod members suspended from ceiling slabs, steel beams, etc., and the length of the support members shall be The spacing approximately corresponds to the gap between the rod members.

However, according to this method, the support fixed to the hanging rod member is attached and supported via the connecting device that is attached to the end of the support member from the outside in the extending direction of the end, so that the hanging rod member and Between the support member,
Because it is necessary to arrange the connector at the end of the support member in the length direction, the support member cannot be longer than the gap between the hanging rod members, and the number of wires supported increases and the support member becomes long. In some cases, it can no longer be installed.

In view of these circumstances, the applicant proposed Utility Application No. 62-42565 by clamping the lip portion of the support member with clamp bolts, nuts, and clamp pieces, so that the connector can be moved in the lateral direction of the support member. We have proposed a support device that uses hanging rod members that are attached from the ground, and even if the support member is long enough, it can be installed without being restricted by the hanging spacing of the hanging rod members.In addition, when the load is large, three or more It can also be supported by hanging rod members.

Further, in the device disclosed in Japanese Utility Model Application Publication No. 60-58983, presser pieces that come into contact with the outer surface of the support member are formed vertically in the shape of a groove in cross section only on both side edges of the clamping piece of the connector. Ta.

(Problem to be solved by the invention) However, these conventional support devices do not connect the support device fixed to the hanging rod member through a coupling device that is attached to the end of the support member from the outside in the direction in which the end extends. It is necessary to use different supporting devices depending on whether the connecting tool is attached and supported from the side of the supporting member or the connecting device is attached and supported from the side of the supporting member.
When adding various types of equipment after the construction of a building, factory, etc. is completed, it is necessary to prepare two types of support devices depending on the purpose, which causes a decrease in work efficiency.

In addition, since the holding piece of the clamping piece of the connector can only come into contact with the outer surface of the support member, the support member can only be fixedly supported on the existing hanging rod member from its length direction. However, it is necessary to prepare two different types of support devices that are adapted to each suspension interval of the hanging rod members, which leads to a decrease in work efficiency. Since it cannot be fixedly supported on existing suspension rod members, it has been impossible to attach a support member that is longer than the hanging interval of the suspension rod members.

Therefore, this invention relates to an improvement on the conventional device described above, and is capable of fixing and supporting the support member to the existing hanging rod member from both the length direction and the lateral direction, thereby reducing the hanging spacing between the hanging rod members. There is no need to prepare two different types of support devices that are adapted to each case.
It is an object of the present invention to provide a support device that uses hanging rod members that can improve work efficiency to various levels and that can attach supporting members that are longer than the hanging distance of the hanging rod members.

(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 arranged so that they face each other above and below the bottom piece. A supporting member having a groove-shaped cross section formed by continuous bending, a supporting member made of lip channel steel disposed between the hanging rod members, and a supporting member that holds the hanging rod member between the supports and the supporting member. It consists of a combination of a connecting device with a substantially L-shaped side surface that is formed to be fixable from both the length direction and the lateral direction, and the connecting device includes a nut that engages the lip portion of the support member from inside, A clamping piece that is sized to be clamped to the upper edge of the supporting member by changing direction in both the length direction and the lateral direction of the supporting member by a clamping bolt that is screwed into the clamping bolt, and a clamping piece that is erected and is attached to the support It consists of a clamping piece that presses and fixes the hanging rod member between its back surface and the support by screwing a tightening screw inserted into the inner bottom piece of the clamping piece. It is characterized by a presser piece that has a width that can be inserted between the parts and that comes into contact with the outer surface of the support member.

(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. While both are set on the hanging rod member, the support member is supported between the coupling members from the length direction or the lateral direction.

In other words, the lip portion of the support member is clamped by a nut that engages with the lip portion of the support member from the inside, a clamping bolt that is screwed into this nut, and a clamping piece that is clamped at the upper edge of the support member, thereby creating a connection. The tool is attached from the length direction of the support member.

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 clamping piece has a size that allows it to be clamped on the upper edge of the support member by changing direction in both the length direction and the lateral direction of the support member; When the lip portion of the support member is clamped, the support member is supported by the suspension rod member by the support and the connector that are connected and supported from the side.

(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 an 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. , has a depth and width corresponding to the diameter of the hanging rod member B.

Reference numeral 6 denotes a supporting member made of lip channel steel that is arranged in a fitted or 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 follows. It is not limited to the shape shown in the figure, but may be the shape or shape.

In order to connect and fix this supporting member 6 to the hanging rod member B in cooperation with the supporting member 1, there is a connecting member 8 whose side surface is approximately L-shaped. It consists of a press stop piece 14. Clamping piece 9
A nut 11 that engages with the lip portion 7 of the support member 6 from the inside and a clamping bolt 10 that is screwed into the nut 11 change the direction of the support member 6 in both the longitudinal direction and the lateral direction. 6. It is formed in a size that can be held between the upper edges. As shown in the figure, a through-hole 1 is opened in the clamping piece 9 for a nut 11 having a planar rectangular or parallelogram shape and engaged inside the lip part 7 while being inserted into the support member 6.
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.

At that time, as shown in the figure, presser pieces 13 are placed on both sides and the tip of the clamping piece 9 and have a width that allows the holding piece 13 to abut against the outer surface of the support member 6 and to be inserted between the lip portions 7 of the support member 6.
It is very preferable to form the holding pieces A and 13B vertically, and when the holding piece 9 is turned in both the longitudinal direction and the lateral direction of the support member 6, the holding piece 13 at the tip
A, either one of the presser pieces 13 on both sides is inserted between the lip portions 7 and the direction change is not obstructed, and one of the other presser pieces 13A, 13B comes into contact with the outer surface of the support member 6, and the support member 6. Eliminates looseness during clamping between the upper edges and increases support stability. And presser pieces 13A, 13B
If the support member 6 has a width that fits between the lip portions 7 of the support member 6, the support stability will be even better.

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.

Furthermore, reference numeral 16 indicates a reinforcing bead formed in a continuous standing portion of the clamping piece 9 and the pressing piece 14.

This invention is constructed as described above, and when used, if there is an existing hanging rod member B that is suspended to support various equipment such as sanitary, air conditioning, electricity, and disaster prevention equipment, Effective for using air conditioning.

That is, the support 1 and the connector 8 are combined and set on the hanging rod member B while facing each other at a predetermined height position corresponding to the duct D, cable rack, large amount of piping, etc. that are planned to be added. The support member 6 is supported between the tools 8 in the longitudinal direction or in the lateral direction. For example, as shown in FIGS. 2 and 4, by clamping the lip portion 7 of the support member 6 with the clamp bolt 10, nut 11, and clamp piece 9, the coupling tool 8 can be moved from the longitudinal direction of the support member 6. Put it on,
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.

In addition, in the case of a supporting member 6 that is longer than the hanging interval of the hanging rod member B, as shown in FIGS. The lip portion 7 of the support member 6 is clamped by the clamping bolt 10, nut 11, and clamping piece 9, and at the same time, the suspension member B is screwed between the support 1 and the pressing piece 14 with the tightening screw 17. Then, the hanging rod member B is sandwiched from the side in a horizontal frame shape and connected and supported.

After that, the duct D, piping, etc. may be placed and set on the support member 6.

(Effects of the invention) Therefore, according to this invention, even if the existing hanging rod members B supporting various equipment are available, if there is a space where they can be used at least in pairs, the necessary ducts D, Cable racks, large amounts of piping, and other extensions can be installed easily and quickly without being hindered by existing equipment.

In particular, since the support member 6 can be fixedly supported on the existing hanging rod member B from both the length direction and the lateral direction, two different types can be used depending on the hanging interval of the hanging rod member B. There is no need to prepare a supporting device, and work efficiency can be greatly improved.

That is, at the tip and both side edges of the clamping piece 9 of the connector 8, there is a presser piece 1 that has a width that allows it to be inserted between the lip portions 7 of the support member 6 and that comes into contact with the outer surface of the support member 6.
By installing 3A and 13B vertically, the connecting tool 8
When the clamping piece 9 is turned in both the longitudinal direction and the lateral direction of the support member 6, the holding piece 13A at the tip,
This is because one of the presser pieces 13B on both side edges can be inserted between the lip portions 7 and prevent the change of direction, and the other presser piece 13A, 13B can be brought into contact with the outer surface of the support member 6. , Two different types of support devices are available that can fixedly support the support member 6 to the existing hanging rod member B from both the length direction and the lateral direction, and are adapted to each depending on the hanging interval of the hanging rod member B. There is no need to do this, and work efficiency can be greatly improved. Furthermore, since the support member 6 can be fixedly supported on the existing hanging rod member B from both the length direction and the lateral direction, it is also possible to install the support member 6 which is longer than the hanging interval of the hanging rod member B. . In addition, the holding pieces 13A and 13B can be held between the upper edges of the support member 6 to eliminate rattling and increase support stability, and the presser pieces 13A and 13B fit between the lip portions 7 of the support member 6. Of course, since it has a wide width, the support stability is even better.

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 in which fitting notches 5 are cut out to fit externally into the hanging rod member B, with the inner bottom pieces 2 facing each other above and below. Therefore, it can be directly attached to any position on 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 duct D, piping, etc. are placed and set is made of lip channel steel, there is no problem with load resistance, and the suspension member B
When the lip portion 7 is connected to the supporting member 6, the lip portion 7 is held by the holding piece 9 having the holding bolt 10 and the nut 11 of the connecting member 8.
The connection between the connector 8 and the connector 8 is reliable.

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 is made up of a press-stop piece 14 that cooperates with the support member 1 and press-fits the hanging rod member B by screwing, the support member 6 can be moved at any position of the hanging rod member B. The arrangement can be fixed and can be used without being affected by existing equipment.

As explained above, according to this invention, when adding various equipment after the building is completed,
It is possible to install piping and other items by using the space between existing hanging rod members, and the supporting member can be fixed and supported to the existing hanging rod members from both the length direction and the lateral direction. There is no need to prepare two different types of support devices that are adapted to each hanging interval of the hanging rod members, and work efficiency can be improved to a great extent. It can be attached, is not restricted by the spacing between the hanging rod members, is not affected by existing equipment, does not get in the way of each other, and has very useful effects in practice, such as being able to carry out work simply and quickly.
