JP2011185024A - Fitting for preventing fall and vibration for post-fittable suspension bolt - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a fitting for solving a problem that a conventional post-fittable-type fitting for preventing vibration is easily disengaged when tension such as pulling is not always applied, and therefor, disruption of a balance in the tension due to the vertical oscillation or horizontal oscillation in the case of earthquake may lead to the disengagement. <P>SOLUTION: The fitting for preventing fall and vibration for a post-fittable suspension bolt is used, so that a body is not come off from a suspension bolt since the fitting is a fit-in type and is fixed with a screw. Further, a long nut with a hole is connected to the body with a long hole, so that a cushion effect is exhibited in the vertical oscillation or horizontal oscillation in the case of earthquake, while the long nut with the hole can correspond to the vertical movement and the leftward/rightward movement, so as to mitigate the impact applied to the body. In addition, for the long nut with the hole, there are a long nut with the hole for a right-hand screw and a long nut with the hole for a left-hand screw, and by utilizing the both a fitting such as a turn buckle is not required. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to steadying of equipment equipment and lighting equipment and prevention of falling.

  Conventional post-mounting metal fittings may come off if the tension is not applied by hanging on the suspension bolt, and there is a risk that they will come off if there is a roll or pitch in the event of an earthquake.

  FIG. 1 shows a conventional post-mounting bracket.

  A description will now be given of the fall prevention / sway prevention metal fitting for attaching the hanging bolt shown in FIG. In the figure, reference numeral 1 denotes a main body, which has a 6-volt biting claw and three elongated holes. The 4 thumbscrews are attached to prevent the unit from coming off. Two-hole long nuts are available for right-hand threads and left-hand threads, and have 7 holes. Install the long nut with 2 holes in the 3 long holes.

  The conventional post-mounting metal fittings described above are easy to come off unless tension such as tension is always applied, and there is a risk that they will come off if the balance of tension is lost due to pitching or rolling during an earthquake.

  Compared with the conventional hooking method as described above, the present invention is fixed with screws, so that the main body does not come off from the suspension bolt, and the two-hole long nut and one main body are connected by three long holes. In addition, there is a cushioning effect on pitching and rolling in the event of an earthquake, and the long nut with two holes can respond to vertical and horizontal movements, reducing the impact on one body. In addition, the 2-hole long nut has 8 right-threaded long nuts and 9 left-threaded long nuts, and the use of both eliminates the need for metal fittings such as tan buckles.

  In order to achieve the above-mentioned object, the present invention screws 8 right-hand threaded long nuts into 12 full threaded bolts by about 2 threads, 1 body fits 10 bolts, 11 inserts, and 4 wing screws are screwed in. Secure with. Screw two 9-threaded long nuts on the opposite side of the 12 full thread bolts. Determine the installation height of 13 equipment suspension bolts according to the length of 12 full thread bolts, push 5 outer bend type openings, tighten 4 thumbscrews, and turn 12 full thread bolts to fix 1 body.

  The operation of the first problem solving means is as follows. In other words, by attaching the fall prevention / sway prevention metal fittings for hanging bolts, it is possible to retrofit to all 13 equipment hanging screw bolts, and to attach 12 screw bolts for shaking prevention without using a metal buckle or the like. In addition, it can cope with up and down and left and right shaking at the time of an earthquake. By screwing a bolt with 15 wires into a long nut with 2 holes, or fixing a bolt with 15 wires into 7 holes with a bolt with 15 wires, 19 system ceiling or 17 downlight etc. Fall prevention is possible.

  As described above, the drop-prevention / sway-prevention bracket for retrofitting the suspension bolt of the present invention can be retrofitted to all 13 screw bolts for hanging equipment, and the 12-thread full-bolt for stabilization can be attached without using a metal fitting such as a tumble buckle. . In addition, it can cope with up and down and left and right shaking at the time of an earthquake. By screwing a bolt with 15 wires into a long nut with 2 holes, or fixing a bolt with 15 wires into 7 holes with a bolt with 15 wires, 19 system ceiling or 17 downlight etc. Fall prevention is possible.

  Hereinafter, an embodiment of the present invention will be described with reference to FIG.

  In the figure, 8 right-hand threaded long nuts are screwed into 12 full thread bolts by about two threads, 1 body is fitted with 10 bolts, 11 inserts are attached, and 4 butterfly screws are screwed in and fixed. Screw two 9-threaded long nuts on the opposite side of the 12 full thread bolts. Determine the installation height of 13 equipment hanging bolts according to the length of 12 full thread bolts, push 5 outer bend type openings and tighten 4 thumbscrews, turn 12 full thread bolts to fix 1 body and To do. Also, push the 5 outer bend type opening into the equipment hanging bolt and tighten the 4 thumbscrews, fix 1 body and screw the 15 wire bolt into the 2 hole long nut, or fix the 15 wire bolt through the 7 hole. In order to prevent the fall of lights such as 19 system ceiling and 17 downlight.

Claims (1)

  A metal fitting that can be retrofitted to all screw bolts for hanging equipment, and that can be used to fix up and down, left and right vibrations during an earthquake by fixing all screw bolts for steadying without using a buckle or other metal fittings. Also, when used in combination with a bolt with wire, it can be used to prevent the lighting of system ceilings and downlights from falling.
