DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. However, the present invention is not limited to the following embodiments, and may be appropriately modified within the scope of the present invention. Can be implemented.

FIG. 1 shows a duct supporting ring 1 according to an embodiment of the present invention, wherein FIG.
FIG. 2B is a left side view, and FIG. 2 is a perspective view illustrating an engagement portion 31 of the band-shaped members 11 and 21.

The duct supporting ring 1 has two strip-shaped members 11 and 21 which can be divided. In this example, two substantially semicircular belt-shaped members 11 and 21 formed so as to fit the outer periphery of the cylindrical duct are combined to surround the outer periphery of the duct. That is, 2
Each of the band-shaped members 11 and 21 has a shape obtained by substantially equally dividing the outer periphery of the duct, and the duct is fitted in a circle formed by the two substantially semicircular band-shaped members 11 and 21. The belt-like members 11 and 21 are usually made of metal or other rigid material.
It is preferable to form a reinforcing rib in the longitudinal direction or the like. The present invention can be applied not only to a cylindrical duct but also to a duct such as a rectangular tube.

Each of the belt-shaped members 11 and 21 has an engaging portion 31 which is rotatably engaged at one end. That is, the belt-shaped members 11 and 21 open and close so that the other end portions are separated or approached with the engagement portion 31 of one end portion as a fulcrum of rotation. In this way, the opening and closing are performed only to facilitate the work of mounting the duct.

The structure of the engaging portion 31 can be, for example, a hook type as shown in FIG. Strip-shaped member 1
At one end, cutouts 13 and 14 are formed on both sides thereof at a distance from the tip 12, and an insertion portion 15 is formed at the center between them. On the other hand, a through hole 23 is formed at one end of the band-shaped member 21 at a distance from the tip 22 and parallel to the tip 22 and with a width slightly larger than the insertion portion 15. The through hole 23 has a substantially T-shape extending so as to narrow toward the side opposite to the tip end.
It is shaped like a letter.

The tip 12 at one end of the strip 11
Is inserted into the through hole 23 formed at one end of the band-shaped member 21 at a predetermined angle.
1 and 21 are engaged with each other so as to be aligned in the longitudinal direction. The band-shaped members 11 and 21 rotate around the hook type engaging portion 31 configured as described above as a fulcrum, and the other ends of the band-shaped members 11 and 21 are separated or approached (arrows in the drawing). Open and close.

The other end of each of the strips 11 and 21 has a connecting portion 41 to which the strips 11 and 21 are connected.
Is provided. The connecting part 41 is for closing and fixing the other ends of the band-shaped members 11 and 21 after the ducts are accommodated and mounted in the band-shaped members 11 and 21 with the band-shaped members 11 and 21 opened.

The connecting portion 41 includes, for example, the band-shaped members 11 and
The other end of 1 is bent outward by approximately 90 ° to form a bent portion 1
7 and 27, the bolts 43 are inserted through the through holes formed in the bent portions 17 and 27, and are fixed with nuts 45, so that the other ends of the band-shaped members 11 and 21 are joined and fixed. Is done. However, the configuration of the coupling portion 41 is not limited to the configuration using the above-described bolts and nuts, and it is needless to say that other appropriate coupling and fixing means can be adopted.

In the present invention, it is important that a mounting portion 51 for attaching to the wall surface of the building is provided at a position apart from the connecting portion 41 of the belt-shaped members 11 and 21. The attachment portion 51 is, for example,
A protruding portion 19 is formed on a part of the belt-like member 11 and the protruding portion 1 is formed.
9 is provided with bolts 53. As shown in the drawing, a bolt 53 is inserted and attached from the inside to the outside of the projection 19 having a flat surface formed on the upper surface, and the belt 53 is attached to the wall surface of the building 61 by the bolt 53. It has become.

The height h1 of the protruding portion 19 is large enough to accommodate the head of the bolt 53, but the mounting member 71 is sandwiched between the bent portions 17 and 27 of the band-shaped members 11 and 21 as in the conventional case. And the distance h2 between the band-shaped member 11 and the wall surface of the building 61 is smaller than that of the conventional one.
Can be shortened, so that the space occupied by the duct can be reduced.

Normally, at the time of construction, a duct is attached after attaching the attaching portion 51 to a wall surface of a building. Since the connecting portion 41 is located at a position away from the mounting portion 51 to the building wall surface, the connecting portion 41 is located at a position away from the building wall surface (located in an open space). This has an advantage that the band-shaped members 11 and 21 can be easily joined at the joining portion 41.

The positional relationship of the mounting portion 51 with respect to the coupling portion 41, that is, how far the mounting portion 51 is separated from the coupling portion 41 is not particularly limited. The portion 51 is located substantially at the center of the belt-shaped member 11 (between the engaging portion 31 and the connecting portion 41). Therefore, the mounting portion 51 and the connecting portion 41 are rotated by 90 ° about the center of the duct as an axis. In a relationship. According to this configuration, the work is easy not only in the case of hanging vertically from the ceiling as shown in the figure, but also in the case of attaching the mounting portion 51 to the side wall of the building in the horizontal direction.

[0023]

As described above, according to the duct supporting ring according to the present invention, when the duct is attached to the band-like member, the band-like member is detached from the attaching member, and the like.
The inconvenience that has conventionally occurred, such as the strip-shaped member falling off, can be solved, and the duct can be reliably and easily constructed.

Also, unlike the conventional one, it is possible to avoid a form in which the belt-shaped member and the other mounting portion protrude outward, so that the space occupied by the duct can be saved.

Further, since a working space can be secured in the joining operation of the belt-shaped members at the joint, there is an advantage that the joining operation of the belt-shaped members at the joint is easy.
