[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, 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. Prepare the connecting metal fitting 1 and the pedestal metal fitting 2 in advance, and similarly cut an L-shaped steel material having an elongated hole to a required length according to the size and quantity of ducts and pipes, and form the elongated hole 3a. The two leg members 4 and 4 and the horizontal member 6 having the long holes 5a are made at the installation work site, and the upper and lower ends of the leg members 4 and 4 and both ends of the horizontal member 6 are attached to the left and right connecting fittings 1 and 1. Align each oblong hole 3a, 5a with the oblong hole 1a of the vertical portion 1c and the horizontal portion 1d of the left and right connecting tools 1, 1 and tighten them with bolts 7 and nuts 8 as shown in FIG. Attach the pedestal metal fittings 2 and 2 to the lower ends of the leg members 4 and 4 of the Itasa was similarly bolt by clamping with the nut, had assembled support cradle 1 0.

Then, racks, ducts, etc. are fixed to the elongated holes 5a of the horizontal member 6 of the support frame 10 assembled in this way 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 11 and the nut 12.

[0005]

[Problems to be solved by the device]

 However, the two connecting tools 1 and 1 obtained by bending the L-shaped steel material having the long holes at a right angle, and the leg member 4 and the horizontal member 6 made of the L-shaped steel material having the long holes are assembled and supported. To make the gantry 10, the horizontal member 6 or the leg member 4 is held on the back side of the connector 1 with one hand so that the elongated holes are aligned with each other, and the bolts are attached from the front side of the connector 1 as shown in FIG. 7 is inserted between the aligned long holes 1a, 5a or 1a, 3a, and a nut 8 is screwed from the rear side of the horizontal member 6 (or leg member 4) to the tip of the bolt 7, and then the connecting tool. Since it is necessary to tighten the bolts while holding both 1 and the horizontal member 6 (or the leg member 4) by hand, there is a problem that the assembling work is extremely complicated and takes a lot of time.

Further, since the connecting tool 1 and the horizontal member 6 (or the leg member 4) are held by hand so as not to separate from each other and bolted, it is difficult to obtain a perpendicularity between the horizontal member 6 and the leg member 4. However, there is a problem that the support base 10 is distorted and is easily tilted 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.

Further, in order to fix the horizontal member 6 to the horizontal portion 1d of the connection tool 1 by bolting without distortion, as shown in FIG. 26, the horizontal portion 1d is provided with the bolts in the elongated holes 1a at least at two places. The horizontal portion 1d of the connection tool 1 needs to have a sufficient length because it needs to be fastened.

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

Further, as shown in FIG. 28, when fixing the pipe B or the like with the U-shaped bolt 11 and the nut 12, the nuts 12 of two adjacent U-shaped bolts 11 can be respectively tightened with a tool. Since a space for inserting a tool is required between the two, the support pitch P of the cable, the pipe B, etc. becomes large, the number of supports for the cable, the pipe B, etc. is limited, or the horizontal member 6 There is also a problem in that the horizontal length must be increased, and the lateral width of the support frame 10 is increased.

Further, although the support base 10 is arranged at a constant interval along the cable, the pipe B, etc., 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 there are deviations in 5a 'and 5a ", it may not be possible to fix the cables, piping B, etc. with the U-shaped bolts 11 and nuts 12. In order to eliminate these deviations, the placement of the support base 10 There is also a problem in that the work becomes extremely complicated due to the deviation of the work or the work of adjusting the mounting position of the horizontal member 6 to the connection fitting 1.

Further, as shown in FIG. 30, it may be necessary to add 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 attached to the 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 with a bolt and a nut, and the second horizontal member 6'is fixed to the horizontal portion 14a of the intermediate connector 14. Thus, in order to extend the second horizontal member 6'into this middle, in order to penetrate the leg member 4 into the intermediate connector 14, as shown in FIG. There was also a problem that the connectors 1 and 1 had to be removed and then the connectors 1 and 1 had to be fixed again.

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

[0014]

[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 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, the both ends of the horizontal member are covered by that much, the effective length for fixing the cable, piping, etc. to the horizontal member is limited, and the number of cables and other supporting parts is limited. Although limited, in the present invention, both ends of the horizontal member 42 are inserted into the main body 21 and tightened by bolts to be connected accurately and without distortion, so that only one bolting point is required. Both ends of the frame member 42 are covered with the main body 21 at only a small portion. 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 should be reduced. You can

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 by 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 frame 40 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 of the two supporting frames of the conventional device shown in FIG. 29 can be solved. It

Further, 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, if the upper wall portion 21d and the side wall portions 21b and 21c are engaged with each other or have an integral structure, the main body 21 will not be deformed even when a large load is applied to the horizontal member.
