Description

  The present invention relates to a hanging tool used to suspend and support various objects such as cable racks and sewer pipes, or air-conditioning ducts and the like by beams made of structural steel such as H-shaped steel. It is about.

  In general, when a suspended object such as a cable rack is suspended and supported by a beam made of structural steel, a hanging tool whose length is adjustable is used.

  As a hanging tool whose length can be adjusted, the one shown in FIG. 6 is conventionally known. In this hanging tool, a pair of nuts 21 and 22 formed with reverse screws are fixed to the inner surface side of the opposed end plate of the square frame-shaped operation frame 20, and the suspension bolt 23 is screw-engaged with one nut 21. In addition, the suspension bolt 24 is screw-engaged with the other nut 22, the lock nuts 25, 25 are screw-engaged with the bolts 23, 24, and the upper end portion of the suspension bolt 23 is connected to the beam A. A connecting tool 26 is attached, and a receiving tool 27 that supports the suspended object B is attached to the lower end of the hanging bolt 24.

  In the hanging tool having the above-described structure, the connecting tool 26 is attached to the beam A made of structural steel and the suspension bolt 23 is suspended and supported, and the height of the receiving tool 27 that supports the suspended object B is set. After the adjustment, the suspension object B is supported by the support 27.

  When adjusting the height of the receiver 27, the pair of lock nuts 25, 25 are loosened, and the suspension bolt 23 and the suspension bolt 24 are moved relatively in the axial direction by the rotation of the operation frame 20. Adjust the length. At this time, the screws formed on the outer circumferences of the suspension bolt 23 and the suspension bolt 24 are reverse screws, so that the receiving device 27 is twice as long as the lead of the screw in the vertical direction per rotation of the operation frame 20. It will move, and the height of the receptacle 27 can be adjusted effectively.

  After adjusting the height of the support 27, the lock nuts 25 and 25 are tightened to fix the suspension bolt 23 and the suspension bolt 24, respectively.

By the way, in the conventional hanging tool, the height adjustment range of the receiver 27, that is, the adjustment range of the length of the hanging tool is opposed to the pair of nuts 21 and 22 fixed to the end plate of the operation frame 20. There is an inconvenience that the length L ₀ is substantially equivalent to the length L ₀ between the faces and the length adjustment amount is small.

  Although the adjustment amount can be increased by using the operation frame 20 having a long length, in this case, since the weight of the hanging tool increases, the operation frame 20 cannot be made longer than necessary.

  Moreover, in the conventional hanging tool, since the screw formed on the outer periphery of the hanging bolt 23 and the hanging bolt 24 is a reverse screw, two types of bolts, a right-handed screw and a left-handed screw, are required, and the cost is high. There is an inconvenience.

  The subject of this invention is providing the cheap hanging tool with a large length adjustment amount and a low cost.

  In order to solve the above problems, in the present invention, a suspension bottle having a connector attached to a beam at one end, and a suspension bolt having a receiver supporting the object to be suspended at the other end, A rod-shaped bolt joint in which a plurality of bolt insertion holes into which the suspension bolt and the suspension bolt are respectively inserted are formed in parallel, and thread engagement with the suspension bolt and the suspension bolt at both ends of the bolt joint. The structure which consists of the made lock nut was adopted.

  In the hanging tool according to the present invention, the bolt joint may be made of an extruded product of aluminum.

  The hanging tool having the above configuration attaches a connecting tool to a beam, and supports the object to be hung by the receiving tool after the height of the receiving tool is adjusted.

  When adjusting the height of the support, either one of the two nuts screwed to the suspension bolt is loosened and the bolt joint is moved along the suspension bolt, or the suspension bolt is threaded. One of the combined nuts is loosened, and the suspension bolt is moved in the axial direction to adjust the position of the support in the vertical direction. After the adjustment, the nut is tightened to tighten the bolt joint. Or fix the hanging bolt.

  As described above, in the hanging tool according to the present invention, the height of the receiving tool can be adjusted by moving the bolt joint in the vertical direction and moving the hanging bolt in the axial direction. Can be moved up and down by an amount approximately corresponding to the dimension obtained by subtracting the length of the bolt joint from the length of the bolt, and the suspension bolt is obtained by subtracting the length of the bolt joint from the length of the suspension bolt. Since it can be moved by an amount substantially corresponding to the dimension, the length adjustment range of the hanging tool is extremely large, and the height of the receiving tool can be adjusted over a high range.

  Moreover, since the same kind of bolt in which a right-hand thread or a left-hand thread is formed can be employed as the suspension bolt and the suspension bolt, a hanging tool with a low cost can be obtained.

  Here, by making the bolted joint an extruded product of aluminum, it is possible to reduce the weight and cost of the hanging tool.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the hanging tool according to the present invention includes a hanging bolt 1, a hanging bolt 2, and a bolt joint 3 that joins both bolts 1 and 2.
