Abstract

PURPOSE: To provide a piping suspension supporter capable of presenting a damping (vibration-proof) property even with respect to lateral vibration and further capable of reducing cost.CONSTITUTION: In a piping suspension supporter, a band holding part is formed for holding piping by curving one belt-like band body in a ring shape. In both open ends of the belt-like band body, band ends are formed so as to be suspended from a suspension bolt or the like by being connected to a suspension connection member like a turn buckle. A first suspension support pole and a second suspension support pole that are suspended obliquely are engaged to first lock parts at left and right side parts of the band holding part. A third suspension support pole and a fourth suspension support pole that are suspended obliquely are engaged to second lock parts. The four-point suspension support and the one-point suspension support by the suspension bolt are at least totally five-point suspension support.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a pipe suspension support, and in particular, on a mounting surface such as a ceiling slab, various pipes such as water pipes, gas pipes, cooling / heating pipes are shaken in the direction perpendicular to the pipe axis as well as in the pipe axis direction. The present invention also relates to a pipe suspension support tool that supports suspension while preventing or preventing.

  In addition to suspension support by a support member such as a suspension bolt on a mounting surface such as a ceiling slab, one or two suspension support rods obliquely suspended from the mounting surface are added, etc. For example, the techniques described in Patent Documents 1 to 3 include a three-point suspension support or a two-point suspension support by two suspension support rods to achieve a vibration-proof (seismic isolation) structure. Are known.

  The technique shown in Patent Document 1 is a technique that can be suspended and supported at three points by mounting it on an existing tangle buckle and pipe support with the conventional configuration, but requires two plate-like members as other members. For this reason, the increase in the number of parts adds to the complexity of part management at the site and the trouble of mounting.

  Since the technology shown in Patent Documents 2 and 3 is provided with an engaging portion with a suspension support rod on the outer surface of the band holding portion of the pipe support tool, there is no problem of adding new members and parts management and the like. There is no complication or the like, but the cost of the pipe support itself is inevitably increased.

  From the above, it has been found that there is a demand for a pipe suspension supporter that can suppress the cost increase without increasing the labor at the time of parts management or installation.

  Furthermore, when the present inventor has continued earnestly researching the technology, when a strong roll occurs, the pipe support that can be hung from the mounting surface while holding the pipe is a connecting portion between the mounting surface and the suspension bolt. , A load is applied to the connection part between the suspension bolt and the tambuckle, the connection part between the tan buckle and the pipe support and the upper part of the band holding part, etc., especially directly above the part holding the pipe It was found that a large load is applied to the upper end portion of the band holding portion.

  According to the inventor's research, when strong rolling occurs in the techniques shown in Patent Documents 1 to 3, the connection portion between the mounting surface and the suspension bolt, the connection portion between the suspension bolt and the tangle buckle, The connection part between the buckle and the pipe support can exhibit anti-vibration (anti-vibration) properties, but the anti-vibration (anti-vibration) property at the upper end of the band holding part may be insufficient. understood.

  Therefore, the present inventor cuts and raises a part of the band holding portion that holds the pipe to form a locking portion, and the cut and raised locking portion is hung from the mounting surface. The pipe suspension support tool which can be suspended by two or three points by making it possible to engage one or two suspension support rods has been proposed (see Patent Documents 4 to 6).
