Description

  The present invention is mainly used for steadying a suspension bolt that suspends a cable rack, a duct or the like, and particularly relates to a suspension bolt steadying bracket that can be connected to a diagonal support bolt in three directions later.

  Conventionally, the present applicant has previously provided a steady rest described in Patent Documents 1 to 3 as this kind of steady rest.

  Patent Document 1 is a steady-state fitting that connects an oblique support bolt for steadying that is arranged obliquely with respect to a suspension bolt from one direction. A character-shaped fixing member is fixed with a fastening bolt, and a long bolt used for steadying is connected to the end of the connecting member.

  Japanese Patent Application Laid-Open No. 2004-228561 is a steady-state fitting that connects an oblique support bolt for steadying from two directions, and is mounted together with equipment such as a cable rack. That is, it is a metal fitting that is attached and used at the same time at the connecting portion between the suspension bolt and the gantry member on which the cable rack is placed.

  However, in Patent Document 1, it is difficult to adjust the angle of the slanting support bolt for steadying that is disposed obliquely with respect to the suspension bolt. Moreover, since patent document 2 is a metal fitting attached with facilities, such as a cable rack, when attaching by retrofit, unless the nut which fixes the suspension bolt is loosened, it is possible to attach an anti-rest metal fitting. There was inconvenience that it was not possible.

  Therefore, the present applicant has proposed a steady rest fitting of Patent Document 3 that can be retrofitted to an existing suspension bolt and that can be attached with a long bolt for steady rest with adjustable angle. Yes. The steady rests include a pair of sandwiched bodies that are sandwiched between the side surfaces of the suspension bolts, a pair of connecting bolts that are fixed to both ends of the sandwiched body, and a pair that is connected to the connecting bolts so that the vertical angle can be adjusted. And an oblique support. And a diagonal support bolt is connected to this pair of diagonal support bodies with adjustable vertical angle from two directions, and the vertical angle of the diagonal support bolt can be arbitrarily adjusted.

However, since this steady rest metal fitting has a structure in which diagonal support bolts are connected to both end portions of the sandwiched body, it is possible to connect diagonal support bolts in two directions, but diagonal support bolts facing in three directions can be connected simultaneously. It cannot be consolidated.

  Since the earthquake, the demand for increasing the seismic strength of each facility supported by suspension bolts has increased the situation of connecting diagonal support bolts from three directions to the suspension bolts. In this case, in addition to the two-way steady rest fitting in Patent Document 3, it is necessary to combine a one-way steady rest fitting as in Patent Document 1. For this reason, since it becomes the operation | work which mounts two types of steady rest metal fittings to a suspending bolt, the mounting operation in a high place has required much time and effort.

  In addition, the steady rest fitting of Patent Document 3 has a structure in which the diagonal support is connected using a fixing bolt that fixes the sandwiched body to the suspension bolt. Therefore, it was necessary to attach two diagonal support bodies in the position fixed to a suspension bolt. Therefore, since the pair of sandwiched bodies and the two diagonal supports are connected at the same time at the high place, the number of parts to be assembled increases, and the work at the high place leaves a problem in safety.
