BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector used for assembling a support frame for supporting ducts, racks, cables, pipes, etc., in buildings, factories, and other structures, and the connection. A support stand using tools.

[0002]

2. Description of the Related Art Conventionally, for example, ducts, racks, indoors or roofs of buildings, factories, other structures, etc.
In installation work of cables, piping, etc., there are cases in which they are supported by a plurality of support frames at intervals. As a support frame for such a purpose, a gate-shaped support frame has been conventionally used. However, in a support frame that has been created in advance with a certain size in this way, the dimensions of the ducts, the dimensions of the pipes, and the like are often different at each installation site, so the dimensions such as height and width must be adjusted accordingly. There was the inconvenience of having to prepare many different types of support stands.

Therefore, conventionally, as shown in FIG. 26, a 90 ° cutout 1b is provided in an intermediate piece of an L-shaped steel material having an elongated hole 1a, and the cutout 1b is formed by bending at a right angle. The connecting metal fitting 1 and the pedestal metal fitting 2 are prepared in advance, and similarly, the L-shaped steel material having the elongated hole is cut into the required length according to the dimensions and the quantity of the duct or the pipe, and the elongated hole 3 is formed.
The two leg members 4 and 4 having a and the horizontal member 6 having the long hole 5a are made at the installation work site, and the left and right connecting fittings 1 and 1
The upper ends of the leg members 4 and 4 and both ends of the horizontal member 6 are connected to the elongated holes 3a and 5a, respectively, and the vertical portions 1 of the left and right connecting tools 1 and 1 are connected.
c and the elongated hole 1a of the horizontal portion 1d, and tightened and fixed by bolts 7 and nuts 8 as shown in FIG. 27, and pedestal metal fittings 2 and 2 are similarly attached to the lower end portions of the left and right leg members 4 and 4, respectively. The support frame 10 was assembled by matching the holes and similarly tightening and fixing with bolts and nuts.

Then, a rack, a duct or the like is fixed to the elongated hole 5a of the horizontal member 6 of the support frame 10 thus assembled with bolts or the like (not shown), or as shown in FIG.
Connect the cable, piping B, etc. to the U-shaped bolt 11 as shown in
It was fixed by the nut 12.

[0005]

However, two connecting tools 1 and 1 obtained by bending the L-shaped steel material having the elongated holes at a right angle as described above, and the leg member 4 and the lateral member made of the L-shaped steel material having the elongated holes are provided. Assembling the support member 10 by assembling the frame member 6 is performed by holding the horizontal member 6 or the leg member 4 on the back side of the connector 1 with one hand so that the elongated holes are aligned with each other, as shown in FIG. Slotted holes 1a and 5 with bolts 7 fitted from the front side of the connector 1.
a or 1a, 3a, and the horizontal member 6
After the nut 8 is screwed to the tip of the bolt 7 from the back side of the leg member 4 (or the leg member 4), the bolt must be tightened while holding both the connector 1 and the horizontal member 6 (or the leg member 4) by hand. Therefore, there is a problem that the assembly work is extremely complicated and takes a lot of time.

Further, since the connector 1 and the horizontal member 6 (or the leg member 4) are bolted while being held by hand so as not to separate from each other, it is difficult to obtain a right angle between the horizontal member 6 and the leg member 4, There is a problem in that the support frame 10 is distorted and tends to tilt due to the weight of the duct or the like during use.

Further, since the connecting tool 1 is formed by bending the notch portion as described above, the bending portion 1'is weak in strength, and when a large load is applied to the horizontal member 6, the connecting member 1 is connected. There is also a problem that the bent portion 1 ′ of the tool 1 is deformed to open the notch, and the leg member 4 of the support frame 10 is tilted.

A horizontal member 6 is provided on the horizontal portion 1d of the connector 1.
26, it is necessary to bolt the horizontal portion 1d in the elongated holes 1a at a minimum of two places as shown in FIG. 26 so that the horizontal portion 1d of the connector 1 has a sufficient length. Need.

For this reason, a considerable length of both ends of the horizontal member 6 is covered by the horizontal portions 1d and 1d of the left and right connectors 1, 1 so that the cable or the pipe B is inserted in the long hole 5a of the horizontal member 6. Is fixed with a U-shaped bolt 11 as shown in FIG. 28,
The effective length of the horizontal member 6 for fixing cables, pipes, etc. is limited, the number of supporting cables, pipes B, etc. is limited, or the horizontal length of the horizontal member 6 must be increased. There is also a problem that the width of the support frame 10 becomes large.

Further, as shown in FIG. 28, the U-shaped bolt 11
And 2 when adhering pipe B etc. with nut 12
In order to be able to tighten the nuts 12 of the two U-shaped bolts 11 with a tool, a space for inserting the tool is required between the two, so that the support pitch P for the cable, the pipe B, etc.
And the number of supporting cables, pipes B, etc. is limited, or the horizontal length of the horizontal member 6 has to be increased, and the horizontal width of the support frame 10 becomes large. there were.

Further, the support bases 10 are arranged at regular intervals along the cable, the pipe B, etc., but as shown in FIG. 29, the long holes of the horizontal members 6 ₁ and 6 ₂ of two adjacent support bases are provided. If the 5a ′ and 5a ″ are deviated, it may not be possible to fix the cable, the pipe B, etc. with the U-shaped bolts 11 and the nuts 12. In order to eliminate the deviation, the support base 10 is arranged in a dislocated manner. There is also a problem that the work is extremely complicated because the work of adjusting the mounting position of the horizontal member 6 to the connection fitting 1 occurs.

Further, as shown in FIG. 30, it may be necessary to additionally install a second horizontal member 6'in the middle of the leg member 4 to further support ducts, pipes and the like. In such a case, conventionally, as shown in FIG. 30, a leg member 4 made of an L-shaped steel material is formed into an L-shaped hole 13 by using an intermediate connector 14 provided with an L-shaped hole 13 into which the leg member 4 is inserted. The intermediate connector 14 is fixed by a bolt and a nut, and the second horizontal member 6'is fixed to the horizontal portion 14a of the intermediate connector 14. In this way, in order to extend the second horizontal member 6 ′ to this middle, in order to make the leg member 4 penetrate the intermediate connector 14, as shown in FIG. There is also a problem that the connecting tools 1 and 1 have to be removed and then fixed again.

An object of the present invention is to provide a connecting tool and a support frame using the connecting tool that solve these problems.

Since the present invention is configured as described above, in the present invention, both the connecting tool and the assembly member (horizontal member, etc.) are simultaneously held by hand like the conventional device shown in FIG. Without tightening the bolts as they are, or by matching both elongated holes, the end portions of the assembly members such as the horizontal member and the leg member can be inserted into the hollow columnar body 21 through the openings and bolted. Well, as in the conventional device of FIG. 26, the bolt is inserted from the front side of the connecting tool to assemble the assembly member (horizontal member, etc.).
Since the assembly member is fixed by simply inserting it from the opening of the main body 21 and tightening it as it is without screwing the nut from the back side of the nut and bolting it, the assembly work is remarkably simple and the work time is remarkably shortened. Is possible.

Further, in the conventional apparatus shown in FIG. 26, in order to connect the horizontal member with the connecting tool accurately and without distortion, it is necessary to provide at least two bolt fixing points in the horizontal portion of the connecting tool. The length of the horizontal part of the connection tool becomes large,
Both ends of the horizontal member are covered by that amount, and the effective length for fixing the cables and pipes to the horizontal member is limited, and the number of supporting cables and the like is limited. Since both ends are inserted into the main body 21 and tightened with bolts to be connected accurately and without distortion, only one place for bolting is required. Therefore, both ends of the horizontal member 42 are covered with the main body 21 at only a small portion. Absent. Therefore, the effective length of the horizontal member 42 that can support the cables and pipes is not limited, and the number of cables and pipes supported is not limited. Therefore, the horizontal width of the support frame can be reduced. You can

If a lip groove type steel material is used as the horizontal member 42, the cable, the pipe B, etc. can be fixed between the lip edges by a fastener as shown in FIG.
Support pitch of adjacent pipes B etc. can be made extremely small,
Alternatively, since it can be supported in a close contact state, FIG.
It is possible to solve the problem of the conventional device shown in (4) and increase the number of supports, and it is also possible to reduce the lateral width of the support frame 40.

Similarly, if a lip groove type steel material is used as the horizontal member 42, a complicated problem such as the adjustment of the mounting position due to the displacement of the mounting positions of the two supporting frames of the conventional apparatus shown in FIG. 29 can be solved. It

If a lip groove type steel material is used as the leg member 41, as shown in FIG. 19, a horizontal member can be easily added in the middle portion without removing the connecting tool 20.

Further, the upper wall portion 21d and the side wall portions 21b, 21
With a structure in which c is engaged or an integral structure, the main body 21 is not deformed even when a large load is applied to the horizontal member.
