2. Description of the Related Art Conventionally, when a tubular member such as an air-conditioning blow-off pipe is suspended and supported below a ceiling of a building structure, a fixing member such as an insert member or an anchor member is attached to a lower surface of a ceiling base at a site. Then, an inverted U-shaped member is attached to a lower portion of the hanger bolt connected to the fixing member, and a metal band for supporting the tubular member is attached to the inverted U-shaped member.

[0003] The metal band is curved along the circumference of the tubular member to be supported, and both ends of the metal band are formed as mounting portions connected to the lower end of the inverted U-shaped member through bolts. (Such as a stainless steel plate).

However, recently, the above-mentioned tubular members are often coated with a resin or the like, and there is a problem that the surface is damaged by a metal band such as stainless steel. Therefore, when such a tubular member is used, a band is created by cutting a cloth scroll in accordance with the dimensions of the tubular member on the site to form a band, and holes are provided at both ends for bolts to pass through. Thus, it is designed to be attached to the inverted U-shaped member.

[0005]

As described above, among the bands of the suspenders conventionally used, the metallic band has a risk of being damaged when the tubular member is suspended, while the band of the tubular member has a risk of being damaged. There is a problem in that the flexibility required for adapting to dimensions is poor.

On the other hand, in the case of a cloth band, when a tubular member is hung at a work site, a material must be prepared and a band must be prepared each time, so that it is troublesome and the prepared band breaks. There was a problem in workability and durability.

An object of the present invention is to solve the above problems,
An object of the present invention is to provide a pipe hanger excellent in workability and durability on site.

[0008]

According to a first aspect of the present invention, there is provided:

And a band made of cloth or other flexible material surrounding the pipe at the annular portion.

In a second aspect of the present invention, the through hole is
A nut through which the hanger bolt is screwed is formed so as to be loosely insertable, and a bottom portion of the nut is provided with a retaining portion for preventing the nut from coming out of the through hole upward,
A locking portion for preventing the nut from coming out of the through hole downward is provided on the upper inside of both sides of the inverted U-shaped member.

[0010] In a third aspect of the present invention, holes are provided at opposing portions of both side walls of the inverted U-shaped member, and the band has holes at both ends thereof for passing connecting bolts. The connection bolts are passed through holes in both side walls of the inverted U-shaped member to be coupled to the lower end of the inverted U-shaped member.

[0011] In a fourth aspect of the present invention, the band is:
The cloth strip is formed by folding a long strip of cloth along a center line extending in the longitudinal direction thereof and sewing both side edges together.

[0012]

According to the first aspect of the present invention, the lower end of the hanger bolt hung at a predetermined place such as the inside of a building via a hanger is screwed into the through hole of the inverted U-shaped member. By passing through, the inverted U-shaped member is connected. On the other hand, the tubular member constituting the pipe is surrounded by the band, and both ends thereof are connected to the lower ends of both side walls of the inverted U-shaped member, so that the pipe is held in the annular portion formed by the band. . In this way, the piping for air conditioning and the like is suspended and supported below the ceiling of the building structure.

[0013] By using the pipe hanger of the present invention, there is no need to prepare and attach a band each time to a tubular member at a work site, and work can be performed easily and efficiency can be improved.

The width and length of the band used for the pipe hanger of the present invention can be freely selected according to the purpose, and are made of a material having excellent flexibility. Examples of such a material include the same resin material as the material for covering the piping tubular member, a material obtained by attaching an aluminum foil to a glass cloth, or a material obtained by coating a glass cloth with a vinyl chloride resin on both sides. According to such a material, there is no problem that the tubular member is damaged by a metal band such as a conventional stainless steel material, and the band itself is excellent in corrosion resistance and the strength required as a support member can be secured.

According to the second aspect of the present invention, the through hole of the inverted U-shaped member is formed so that the nut through which the hanger bolt is screwed can be loosely inserted, and the retaining portion is formed at the bottom of the nut. This prevents the nut from coming out upward.
In addition, by forming a locking portion on the upper inside of both side walls of the inverted U-shaped member, the nut is prevented from falling out of the through hole downward. Since the nut screwed to the hanger bolt is loosely connected to the inverted U-shaped member to which the band is connected, the inverted U-shaped member swings relative to the hanger bolt suspended and fixed to the ceiling or the like. It is possible to work by tilting the inverted U-shaped member or the band when installing the pipe.

According to the third aspect of the present invention, the inverted U-shaped member is formed with holes at opposing portions of both side walls, and the both ends of the band are formed with holes through which connecting bolts pass.
The band is attached to the lower end of the inverted U-shaped member by passing the connecting bolt through the hole of the band and the holes on both side walls of the inverted U-shaped member.

According to the fourth aspect of the present invention, both side edges in the longitudinal direction of the band are sewn, so that the band is not broken during the operation and the durability of the band is improved.
