Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe saddle used for fixing pipes for gas, water, etc. to a floor or the like.

[0002]

2. Description of the Related Art Conventionally, pipe saddles used for fixing pipes for electric wiring or water pipes or sheath pipes thereof to a floor surface and the like have been disclosed in Japanese Utility Model Publication No. 54-134322 and Japanese Utility Model Publication No. 61322. As described in Japanese Patent Publication No. 75573, etc.,
It is used that a metal plate is formed into an Ω type, an annular part of the Ω type member is attached to a pipe, and each of the horizontal legs of the Ω type member is fixed to the floor surface with concrete screws or the like. In addition, Japanese Utility Model Publication No. Sho 49-104015 and Japanese Utility Model Publication No. 5-20946.
As described in Japanese Patent Publication, there are also known ones in which the Ω type member and the pedestal are made of a synthetic resin material.

[0003]

Since the plumbing work is difficult to mechanize and is carried out entirely by hand, the improvement of the saddle for piping is aimed at achieving ease and simplicity of work without weakening the mounting strength. Has been done in various ways. In the conventional piping saddle, the horizontal leg of the Ω type member is fixed to the floor surface with two concrete screws, or the pedestal is first fixed to the floor surface with two concrete screws, etc. A method of fixing the Ω type member to the pedestal without using screws is used.

In the method of sequentially attaching Ω-shaped members to the pipes temporarily arranged on the floor or the like to fix the pipes, it is necessary to tighten the screws to the legs of the Ω-shaped members while holding the pipes. It is complicated because it does not happen. Also, with the method of attaching the pedestal in advance, it is necessary to fix the pedestal at a right angle to the pipe arrangement direction, and if the mounting position of the pedestal is displaced, piping will be impossible, so it is quite accurate. It has been pointed out that workability deteriorates due to the need for space.

In view of the above, it is an object of the present invention to provide an improved piping saddle that is easy to use, has high workability, and is capable of easily adjusting the displacement in the mounting direction.

[0006]

A piping saddle according to the present invention comprises a pedestal metal fitting and a wedge metal fitting, and a screwing through hole is provided at approximately the center of the bottom of the pedestal metal fitting. In addition, a pair of notches for inserting both protrusions of the wedge metal fitting are formed near both ends of the pedestal metal fitting, and the upper side of the notch portion is directed toward the intrusion direction of the wedge metal fitting. Is inclined downward, and a step portion into which the protruding piece of the wedge metal fitting falls is formed above or below the cutout portion. The wedge metal fitting has an arc-shaped cross section, and the pedestal described above is provided on both sides. The present invention is characterized in that a projecting piece to be inserted into the cutout portion of the metal fitting is formed.

1 is an exploded perspective view of a piping saddle according to the present invention. In FIG.
Reference numeral 0 denotes a pedestal metal fitting, which is composed of a pedestal portion 12 in which one screw-through hole 11 is formed in the central portion, and a pair of arc-shaped portions 13 for holding the pipe.
A notch 14 for inserting a projection piece 21 of a wedge metal fitting 20 described later is formed in each of the above. The line on the upper side of the notch portion 14 is inclined downward in the direction in which the wedge metal fitting 20 enters, and forms a step portion 15 from the middle.

The wedge metal member 20 has an arc-shaped cross section, and the protrusions 2 are provided at both ends.
1 is formed, and the bent portions 22, 23 are formed at the rear end and the front end.
Are formed. The rear end bent portion 22 is used when the wedge metal fitting 20 is inserted into the notch portion 14 of the pedestal metal fitting 10, and therefore is not always necessary if it is formed by hitting with a tool such as a punch. Not an element. Alternatively, a resin material having a concave cross-section may be attached instead of the bent portion 22.

The front end bent portion 23 is for improving the slipperiness between the wedge metal fitting 20 and the tube, and is particularly effective when the surface of the tube is a sheath tube having irregularities.

As described above, since the upper line of the notch portion 14 is inclined downward in the direction in which the wedge metal fitting 20 enters, when both projecting pieces 21 of the wedge metal fitting 20 are inserted into the notch portion 14, The insertion proceeds in an oblique state, and accordingly, a force acts in a direction of pressing the pipe arranged on the pedestal metal fitting 10, and the protrusion 2
When the rear end of 1 exceeds the position of the step portion 15, the projecting piece 21 moves upward and is blocked by the step portion 15 so that it cannot retreat.

Further, as shown in FIG. 2, the present invention also includes a mode in which the upper side of the notch portion 14 is only inclined downward toward the direction of entry of the wedge metal fitting 20 and the step portion 15A is formed on the lower side. To be done.

In FIG. 2, reference numeral 16 is a rib,
When the sheath tube is fixed, the sheath tube is made to project inward so as to engage with the recess formed in the surface of the sheath tube. This rib 16
May be singular as shown or plural. This rib 16 is also preferably provided in the embodiment of FIG.

3 and 4 show another embodiment of the pipe saddle according to the present invention (a schematic view in which the thickness of the material is omitted).

In the embodiment shown in FIG. 3, the wedge metal fitting 20 is attached to the pedestal metal fitting 10 in a lateral position.
In this embodiment, an opening 17 is prepared for an electric screwdriver used when attaching a concrete screw or the like through the screw fastening through hole 11.

In the embodiment shown in FIG. 4, the pedestal metal fitting 10 is divided into two members in order to facilitate the work of fixing to the floor or the like, and the opening 18 and the hook 19 make it detachable. Has been done.

In the embodiment shown in FIG. 4, the opening 18
The present invention also includes a configuration in which a hinge mechanism is used instead of the engaging means by the hook 19 and the hook 19.

In order to fix the pipe to the floor or the like by using the pipe saddle according to the present invention, first, the pedestal metal fitting 10 is fixed to the floor surface by the concrete screw or the like using the screwing opening 11. Then, the tubes are arranged in the inner space of the pedestal metal fitting 10. At this time, even if the mounting direction of the pedestal metal fitting 10 deviates from the arrangement direction of the pipes, since the pedestal metal fitting 10 has only one fixed position, the mounting direction can be easily adjusted by rotating around the fixed position. can do. Since the pedestal is fixed at two points in the conventional piping saddle,
In the above case, it is necessary to remove at least one screw and fix it again. In this respect, it is clear that the piping saddle according to the present invention has good usability. Further, in the conventional piping saddle, which is fixed to the floor or the like with two concrete screws, it is obvious that the piping saddle of the present invention, which is one stop, can be shortened to a working time of 1/2. is there.

After the pipes are arranged on the base metal fitting 10, the wedge metal fitting 2
0 is attached to the notch 14 of the base metal fitting 10. As described above, at this time, since the wedge metal fitting 20 is inserted along the line above the notch which is in the inclined state, the pressing force against the pipe increases as the insertion progresses. At the final stage of insertion, the protruding piece 21 of the wedge member 20 exceeds the position of the step portion 15 of the cutout portion 14, and therefore, the backward return is impossible. The above work completes the fixing of the pipe.

When the pipe to be fixed is deformed by pressing like a sheath pipe, the wedge metal member 20 is pushed upward by the repulsive force from the pipe side, so that a stronger fixation is possible. Becomes

In the piping saddle of the embodiment shown in FIG. 3, the work of fixing the pedestal metal fitting 10 to the floor or the like differs only in that the opening 17 is used. Further, the piping saddle of the embodiment shown in FIG. 4 is different only in that the pedestal metal fitting 10 is united by the engaging means.

The present invention also includes a configuration in which two or more screw-fastening through holes 11 are provided so that either one can be selected in accordance with the condition of the mounting position of the pipe, or a configuration in which the holes are elongated holes. .

[0022]

According to the piping saddle according to the present invention, the pedestal metal fitting 10 is fixed to the floor or the like at one point only at the position of the screw-fastening hole 11, so that it is conventionally fixed at two points. It is advantageous in shortening the working time as compared with. Also,
According to the configuration of the present invention, the mounting direction can be easily adjusted without reattaching the screw, and thus the usability is very good as compared with the conventional product.

Further, the tube is fixed to the pedestal metal fitting 10 by
Since it can be firmly performed only by inserting (driving) the wedge metal fitting 20 in an oblique direction, it is very advantageous in improving workability in addition to the above-mentioned advantages. In addition, since the wedge technique in which the tightening force increases with driving is used, the fixing force of the pipe is strong, and there is no fear that the pipe will come off when the operator's foot is caught.
