Description

[Detailed description of the device]

[0001]

[Industrial applications]

 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 a support frame using the connector. .

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, in installation work of ducts, racks, cables, pipes, etc., such as indoors or rooftops of buildings, factories, other structures, etc., they may be supported by a plurality of support frames at intervals. As a support base for such a purpose, a gate-shaped support base is conventionally used. However, in a support frame that has been created in a certain size in advance, the dimensions of ducts, pipes, etc. 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 various types of support frames of different types.

Therefore, conventionally, as shown in FIG. 26, connection fittings 1 and 2 and pedestal fittings 3 and 4 made by bending an L-shaped steel material having elongated holes 1a and 2a into a rectangular shape have been prepared in advance. Similarly, an L-shaped steel material having long holes is cut into a required length according to the dimensions and the number of ducts and pipes, and two leg members 5 having long holes 5a and 6a as shown in FIG. , 6 and the horizontal member 7 having the long holes 7a are made at the installation work site, and the upper and lower ends of the leg members 5, 6 and the both ends of the horizontal member 7 are attached to the left and right connecting fittings 1, 2, respectively, in the long holes 5a, 6a. , 7a are aligned with the elongated holes 1a, 2a of the connecting tools 1, 2 respectively, and are tightened and fixed by bolts 9 and nuts 10 as shown in FIG. 27, and fixed to the lower ends of the left and right leg members 7, 7. In the same way, make the pedestal metal fittings 3 and 4 match the oblong holes, and similarly tighten and fix with bolts and nuts. Therefore, the support base 11 was assembled.

Then, racks, ducts, and the like are fixed to the elongated holes 7a of the horizontal member 7 of the support frame 11 thus assembled with bolts (not shown), or as shown in FIG. As described above, the cable, the pipe B and the like are fixed by the U-shaped bolt 12 and the nut 13.

[0005]

[Problems to be Solved by the Invention]

 However, the support pedestal 11 is constructed by assembling the connection tools 1 and 2 obtained by bending the L-shaped steel material having the long holes at a right angle, the leg members 5 and 6 and the horizontal member 7 made of the L-shaped steel material having the long holes. The work of creating the is to hold the horizontal member 7 or the leg members 5 and 6 on the back side of the connection tools 1 and 2 with one hand to match each long hole, and to connect the connection tools 1 and 2 as shown in FIG. Insert the bolt 9 from the front side into the aligned long holes, and screw the nut 10 onto the tip of the bolt 9 from the back side of the horizontal member 7 (or the leg members 5 and 6), and then connect the horizontal member with the connector. Since it is necessary to perform bolting while holding both members (or leg members) by hand, there is a problem that it is extremely complicated and takes a lot of time.

Further, since the connectors 1 and 2 and the horizontal member 7 (or the leg members 5 and 6) are held by hand so as not to separate from each other and bolted, the horizontal member 7 and the leg members 5 and 6 are However, there is a problem that the support pedestal 11 is distorted and tends to tilt due to the weight of the duct or the like during use.

Further, in order to fix the horizontal member 7 to the horizontal portions 1b and 2b of the connection tools 1 and 2 by bolting without distortion, at least two places are required for each horizontal portion 1b and 2b as shown in FIG. Therefore, the horizontal portions 1b and 2b of the connectors 1 and 2 need to have a sufficient length because bolting is required. For this reason, when fixing a cable, a pipe B, or the like to the elongated hole 7a of the horizontal member 7 with the U-shaped bolt 12, a considerable length at both ends of the horizontal member 7 causes the horizontal portions of the connectors 1 and 2 to be flat. Since it is covered with 1b and 2b, the effective length of the horizontal member 7 for fixing cables, pipes, etc. is limited, and the number of supporting cables, pipes B, etc. is limited, or the horizontal member 7 There is also a problem that the horizontal length of the support pedestal 11 must be increased, and the width of the support frame 11 is increased.

Further, as shown in FIG. 28, when fixing the pipe B or the like with the U-shaped bolt 12 and the nut 13, the nuts 13 of two adjacent U-shaped bolts 12 can be tightened with a tool respectively. Since a predetermined space is required between the two, the supporting pitch P of the cable, the pipe B, etc. becomes large, and the number of supporting cables, the pipe B, etc. is limited, or the horizontal direction of the horizontal member 7 is limited. The length of the support pedestal must be increased, and the width of the support base 11 becomes large.

Further, although the support pedestals 11 are arranged at regular intervals along the cable, the pipe B, etc., as shown in FIG. 29, the long holes of the horizontal members 7 ₁ and 7 ₂ of the two adjacent support pedestals are formed. If there is a deviation between 7a 'and 7a ", it may not be possible to fix the cables, piping B, etc. with the U-shaped bolts 12 and nuts 13. In order to eliminate this deviation, the support base 11 should be arranged. There is also a problem in that the work of misaligning or adjusting the mounting position of the horizontal member 7 to the connection fittings 1 and 2 becomes extremely complicated.

As shown in FIG. 30, it may be necessary to add an additional second horizontal member 7 ′ between the leg members 5 and 6 to further support ducts and pipes. In such a case, conventionally, as shown in FIG. 30, a leg member 5 made of an L-shaped steel material is made into an L-shaped hole by using an intermediate connector 15 provided with an L-shaped hole 14 into which the leg member 5 is inserted. The intermediate connecting device 15 is fixed to the intermediate connecting device 15 with a bolt and a nut, and the second horizontal member 7'is fixed to the horizontal portion 15a of the intermediate connecting device 15. In order to extend the frame member 7 ', there is also a problem that it is necessary to remove the already-fixed connectors 1 and 2 shown in FIG.

An object of the present invention is to provide a connection tool and a support frame using the connection tool that solves the above problems.

[0012]

[0046]

[Effect of device]

 Since the present invention is configured as described above, in the present invention, as in the conventional device shown in FIG. 26, bolts are tightened while simultaneously holding both the connector and the assembly member (horizontal member) by hand. Or the ends of the assembly members such as the horizontal members and the leg members can be inserted into the hollow columnar main body 21 through the openings and tightened with the bolts, In addition, as in the conventional device of FIG. 26, the bolt is inserted from the front side of the connector, and the assembly member is opened in the main body 21 without screwing the nut from the back side of the assembly member (horizontal member) and tightening the bolt. Since it is fixed simply by inserting it from the part and tightening it with bolts, the assembly work is much easier and the work time can be significantly shortened.

Further, in the present invention, if the horizontal member is sized to fit in the hollow portion of the main body 21, the assembly member is positioned in the hollow portion of the main body 21 as it is when inserted into the main body 21 through the opening. Therefore, the horizontal member 42 and the leg member 41 can be accurately connected to each other perpendicularly, and there is no possibility that the supporting base 40 is distorted or tilted by the supporting weight during use.

Further, in the conventional device 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, and both ends of the horizontal member are covered by that much, and the effective length for fixing the cable, piping, etc. to the horizontal member is limited, and the number of supports such as cables is limited. Although limited, in the present invention, both ends of the horizontal member 42 can be accurately positioned without being distorted by inserting them into the main body 21, so that only one bolting point is required. Is covered with the body 21 only to a small part. 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 lateral width of the support frame can be reduced. be able to.

Further, 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 with a fastener as shown in FIG. Since the support pitch such as can be remarkably reduced or can be supported in a close contact state, the problem of the conventional device shown in FIG. 28 can be solved and the number of supports can be increased, and the width of the support base 50 can also be reduced. can do.

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 in the two supporting frames of the conventional device 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. 24, a horizontal member can be easily added in the middle portion without removing the connecting tool 20.
