DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe suspension band for fixing a pipe below a floor of a building, behind a ceiling, or along a wall surface.

[0002]

2. Description of the Related Art When plumbing pipes such as water pipes under the floor of a building, behind a ceiling, or along a wall surface, several fittings for fixing pipes have been developed. The fittings for suspending the pipes are called pipe fixing fittings, and are manufactured by Akagi Co., Ltd. (2-28-7 Shinkawa, Chuo-ku, Tokyo, Phone 03-3552-733).
Numerous types are introduced on pages 26 to 82 of the catalog "Akagi-type piping support fittings" issued by 1) in 1998. One of the typical fittings of the pipe fixing fitting is a hanging band for piping. This hanging band for piping is disclosed in Japanese Unexamined Patent Publication No. 9-152.
The description is given in the specification of the suspension band for piping No. 063. The hanging band for piping shown in FIG. 8 as a conventional example of the above specification is one of the most common ones. This example is drawn again in FIG. 6 of the present specification. FIG. 6 is a perspective view of a conventional suspension band for piping. Arc-shaped piping bands 101 and 102 connected by a hinge mechanism 100 are
It is further suspended on a turnbuckle 104 suspended on a suspension bolt 103. A bolt 105 and a nut 106 are used to attach the suspension band to the turnbuckle. The ends of the piping bands 101 and 102 are bent at a right angle, and are further provided with bolt holes to stand up. This portion corresponding to each piping band 101, 102 will be referred to as bolted wings 107, 108. It is fixed with bolts and nuts as depicted in FIG. The portions through which the bolts pass are indicated by dotted lines in the figure. Various types of pipe hanging bands have been developed, but most of them basically have the structure shown in FIG.

[0003]

In the case of the hanging band for piping shown in FIG. 6, there is a concern that bolts and nuts, and the piping and the hanging band for piping itself may drop during actual construction. This concern has been raised as a problem in many patent applications including Japanese Patent Application Laid-Open No. Hei 9-152563. In Japanese Unexamined Patent Application Publication No. 9-152063, a nut 106 in FIG.
And a technique for fixing the bolt 105 to the bolted wing 107 so as to be freely rotatable. With this technology, the danger of falling bolts and nuts independently has been eliminated.
This technology is sold by Akagi Co., Ltd. under the trade name "Hayatsuri". However, no measures have been taken with regard to the fear that the pipe will fall off the suspension band during the mounting operation in this "chatter". JP-A-9-15206
In Fig. 7 of Fig. 3, there is introduced a device to prevent the pipe from rolling down by devising the dividing position of the piping band, and a certain effect can be expected. However, it is necessary to consider the securing of an opening for fitting the piping. If the piping is shaken greatly inside, there is a risk of falling.

[0004]

In the hanging band for piping of the present invention, the receiving side hanging band 1 and the covering side hanging band 2 are connected at one end by a hinge mechanism 100;
The outer peripheral surface of the receiving-side suspension band and a part of the inner peripheral surface of the covering-side suspension band overlap and contact, or, in addition,
The receiving side suspension band and the covering side suspension band are partially in contact with each other.

[0005]

In the hanging band for piping according to the present invention, one end of the receiving side hanging band 1 and the covering side hanging band 2 are connected to the hinge mechanism 1.
00 and both the outer peripheral surface of the receiving-side suspension band and a part of the inner peripheral surface of the covering-side suspension band overlap and come into contact with each other. By suppressing the loosening of the overlap by a frictional action or the like, it is possible to suppress the pipe from falling down from the pipe suspension band. The strength can be adjusted by adjusting the surface condition of the overlapping surface. The strength can also be adjusted by adjusting the curvature of the outer peripheral surface of the receiving side suspension band and the curvature of the covering side suspension band. For example, by making the curvature of the cover-side suspension band steep, the overlapping portion is less likely to come off. Since the temporary holding of the overlap is not performed by a troublesome bolt, it can be easily attached and detached. In addition to the above features, when the receiving side suspension band and the covering side suspension band partially contact each other, the degree of freedom of the temporary holding mechanism is increased. The strength of the temporary holding can be changed by adjusting the degree of contact between the side portions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a front view of a pipe suspension band of the present invention, and FIGS. 2 and 3 are a perspective view and a front view showing an actual use form thereof. The following parts are iron unless otherwise noted. Reception side suspension band 1 and hinge mechanism 10
The cover-side suspension band 2 fixed at 0 is a main component. A receiving-side bolt retaining wing 3 is provided at one end of the receiving-side suspending band, and a covering-side bolt retaining wing 4 is provided at one end of the covering-side suspending band. The receiving-side bolt retaining wing is provided with a through hole, through which the bolt 105 passes. A nut 106 is attached to the cover-side bolt retaining wing 4 by welding. The cover side suspension band is further provided with a cover overhang 5 as shown in the figure. FIG. 2 shows how the pipe 109 is actually fixed by the pipe hanging band. There are various types of piping, such as iron pipes and embi tubes. 2 shows a state in the middle of the work of wrapping the pipe 109 with the suspension band of FIG. The receiving side suspension band 1 is in contact with the pipe, but cannot be seen in the drawing behind the pipe. The hinge mechanism 100 is visible below the pipe. The cover-side suspension band 2 is attached with the cover-side bolt retaining wing 4 to which the nut 106 is welded. Hole and turnbuckle 104 provided in receiving bolt retaining wing 3
Then, the pipe is fixed by passing the bolt 105 through the hole provided in the hole and the hole of the receiving bolt retaining wing 4. The overhang 5 overlaps so as to cover the outer peripheral surface of the receiving suspension band. The state of this overlap is drawn in an easy-to-understand manner in the front view of FIG. FIG. 3 shows a use form drawn from a direction directly facing the hole of the pipe 109. The inner peripheral surface of the receiving side suspension band 1 is manufactured to have a size that is in close contact with the outer peripheral surface of the pipe. On the other hand, the cover-side suspension band 2 fixed to the receiving-side suspension band by the hinge mechanism 100 is designed so that its inner peripheral curvature is larger than the piping curvature, so that a part thereof does not contact the piping. It is manufactured so that the inner peripheral surface of the overhang 5 is in contact with the outer periphery of the receiving side suspension band. The bolt 105 passes through the receiving-side bolt retaining wing 3, the cover-side bolt retaining wing 4, and the turnbuckle 104 as shown in the figure. A nut (not shown) is attached to the bottom of the bolt. The positions of the holes for the bolts are such that their axes are equal when they are fixed by overlapping as shown in FIG.

FIG. 4 shows an embodiment corresponding to claim 2 of the present invention. FIG. 4 shows an enlarged view of only a portion where the receiving-side hanging band 1 and the covering-side hanging band 2 are joined. The inner surface of the bolt hole provided with the receiving-side bolt retaining wing 3 is threaded so that a nut can be omitted. An overhang 5 is formed in the vicinity of the portion where the overbolt-side bolt retaining wing 4 is provided. The overhang has a blind hole shape in which L-shaped characters are symmetrically arranged as shown in the figure. The narrow opening of this blind hole is large enough to allow the constricted portion of the receiving bolt retaining wing 3 to pass therethrough. When hooked through the constriction, the side surface of the receiving bolt fastening wing and the side surface of the blind hole come into contact. In a natural state, the cover side suspension belt is manufactured so that the curvature of the cover side suspension belt is gentle and the narrow opening of the bag hole hits a position higher than the constricted position, and the curvature of the cover suspension band is temporarily sharpened by hand. If you make it possible to face the constricted position by
Once the blind hole grips the receiving bolt fastening wing, that state can be maintained. If it is desired to remove the curvature, the curvature may be temporarily increased.

FIG. 5 shows an example of a method of manufacturing the overhanging shape shown in FIG. FIG. 5 is an enlarged view of only the end of the cover-side suspension band. A cut is made at the end of the iron band as a cut line 6 as shown in the figure. It rises at a right angle at the part of the line drawn as the folding line 7 in the figure.
Then, finally, the overhang 5 and the over-bolt wing 4
Is completed.

[0009]

According to the present invention, the pipe can be temporarily fixed without troublesome bolting during operation. In the middle of piping work, such as height adjustment work of suspension bolts, various adjustments are made while attaching and detaching pipes, but depending on the adjustment work, work may be performed by removing pipes. Once it is fastened, it is troublesome to remove it. According to the present invention, the pipe can be easily removed, and even if the pipe is temporarily fixed, the risk of the pipe falling off is extremely small. Therefore, the piping work can be performed efficiently and safely. The present invention also has a feature that the manufacturing cost does not increase or can be extremely reduced as compared with the suspension band generally used conventionally.
