The piping work is difficult to be mechanized and is performed manually, and therefore, it is necessary to improve the workability and simplicity of the piping without reducing the mounting strength. Has been done in various ways. In a conventional piping saddle, a method of fixing a horizontal leg of an Ω-type member to a floor or the like with two concrete screws or the like is performed.

In a method of sequentially attaching Ω-shaped members to tubes temporarily arranged on a floor surface or the like and fixing the tubes, it is necessary to tighten the screws to the legs of the Ω-shaped members while holding the tubes. This is rather complicated.

In view of the above, the present inventor has previously proposed an improved piping saddle that is easy to use and high in workability (see Japanese Patent Application No. 8-162296).

Accordingly, the present invention clarifies a method of mounting the pipe saddle at the falling or rising portion of the pipe when the pipe saddle is mounted on a mounting surface such as a ceiling or a floor (further, a wall surface or the like). The purpose is to do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 2 to 4 (FIGS. 3 and 4 are the same as FIGS. 1 and 2 of Japanese Patent Application No. 8-162296, which is the above-mentioned prior art) show a saddle for piping. It is shown in an exploded perspective view. In the figure, reference numeral 10 denotes a pedestal fitting, a single through hole 12 for screwing is formed in a bottom plate 11, and a side plate is a pair of arc-shaped portions 13 holding a pipe. Is the convex portion 14 in the inward direction
Are formed. The convex portion 14 presses a side portion of the pipe arranged so as to be embraced by the arc-shaped portion 13 and locks the pipe so that it cannot escape from the arc-shaped portion 13. In addition, the temporary fixing function by the convex portion 14 is also effective when the pipe is a sheath pipe, and when the saddle is used for hanging the ceiling of the pipe. In addition, it is also preferable to prepare a plurality of through holes 12 for screwing so that the position and number of through holes to be used can be freely selected according to the construction standard.

A notch 15 is formed in a rising portion continuous with the arc-shaped portion 13 for engaging the locking portion 21 of the fastener 20.

The stopper 20 has its engaging portion 21 engaged with the notch 15 of the pedestal fitting 10 and is rotated by operating the operation plate 22 to leverage the tube pressing portion 23 provided at the base end. The pipe is fixed by the
1 and the notch 15 serve as a fulcrum, and the end of the operation plate 22 is a power point. That is, the posture of the stopper 20 shown in FIGS. 2 to 4 indicates a state in which the pipe is fixed, that is, a state of FIG. 1 described later, and has turned counterclockwise from the state shown in FIGS. It is in the state before tightening the pipe in the posture.

It is preferable that the tube pressing portion 23 provided on the base end side of the operation plate 22 bends and be curved substantially corresponding to the outer peripheral shape of the tube having an annular cross section. By making the tube pressing portion 23 curved rather than straight, the contact portion with the surface of the tube becomes longer, and it is possible to prevent only a part of the tube from being deformed when tightened.

Preferably, a stopper 21A is formed at each end of the locking portion 21. Stopper 21A
Is formed, it is possible to prevent the stopper 20 from dropping off even in the case of an accident in which the pedestal fitting 10 is opened for some reason. In the embodiment shown in FIG. 4, the left and right side portions 22A are formed by extending the side ends of the operation plate 22 of the stopper 20 instead of the stopper 21A, and have the same function.

Next, an embodiment of the construction method of the present invention for fixing a ceiling pipe having a falling portion using the pipe saddle having the above-described structure (having the structure shown in FIG. 2) will be described with reference to FIG. I do. In the present embodiment, FIG. 1 is upside down, the ceiling in the following description is replaced with a floor surface, and the falling portion is replaced with a rising portion, which is an explanation of an embodiment of a floor piping having a rising portion.

First, after ink marking for piping is performed,
The pedestal fittings 10 are attached to the ceiling (mounting surface) 1 at predetermined intervals along the black ink. The mounting of the pedestal fitting 10 is performed by driving the concrete nail 2 through a screw hole 12 formed in the bottom plate 11 (or using another fastener). When performing this operation, the stopper 20 is removed.

When the pedestal fitting 10 is mounted on the ceiling (mounting surface) 1, the notch 15 of the pedestal fitting 10 is located on the side of the falling portion of the pipe P.

When the pedestal fitting 10 is fixed to the ceiling (mounting surface) 1, a pipe P is disposed in the space inside the pedestal fitting 10 from below, and then the annular portion 15 of the cutout 15 of the pedestal fitting 10 is provided.
At A, the locking portion 21 of the stopper 20 is attached. At this stage, the operation plate 22 of the stopper 20 is not in the rightward and substantially horizontal posture shown in the figure, but in the state where the operation plate 22 is inclined leftward or leftward and substantially horizontal in the drawing.

After attaching the stopper 20 to the pedestal 10 as described above, the operation of pushing down the operation plate 22 clockwise in the drawing is performed. By pushing down the operation plate 22 in this manner, the tube pressing portion 23 on the proximal end side is strongly pressed against the surface of the tube P by leverage, and the tube P is fixed. To release the fixing of the pipe P, the operation plate 22 may be rotated counterclockwise in the drawing. In addition, since the axis connecting the two locking portions 21 and the notch 15 of the pedestal fitting 10 serve as a fulcrum of the lever action, the end of the operation plate 22 (the point of the lever action) from the axis.
As the length is increased, a large pressing force can be applied with a small force.

The above-described construction method, that is, the notch 15 of the pedestal fitting 10 and the stopper 20 on the falling portion side of the pipe P
When the pedestal fitting 10 is attached to the ceiling (mounting surface) 1 so that the fulcrum of the lever action composed of the locking portion 21 is located, a tensile force acts on the pipe P downward in the direction of the falling portion. (For example, at the time of fixing the pipe P to a lower wall surface or the like, or at the time of pulling down wirings or the like which are conducted inside the pipe P from below), the tensile force acts on the operation plate 22. Since there is no pipe, the stopper 20 and the pipe P
Can be prevented from falling off.

On the other hand, when the pedestal fitting 10 is mounted so that the cutout 15 is located on the opposite side of the falling portion of the pipe P, the position of the operation plate 22 after fixing is located on the falling portion side. Therefore, when a pulling force acts on the pipe P downward, which is the direction of the falling portion, the pulling force acts on the operation plate 22 in a counterclockwise direction in the drawing, that is, in a direction for releasing the fixing of the pipe P. As a result, the stopper 20 and the pipe P fall off from the pedestal fitting 10.
