FIG. 5 is a partial cross-sectional view showing a fitted state of the receiving member and the pipe support in FIG. 1, and FIG. 6 is a cross-sectional view of a main part showing another detaching prevention means of the pipe support in FIG. FIG. 7 is a front view showing another embodiment of the pipe holding portion in the pipe support, and FIGS. 8 to 9 are explanatory views showing an example of use of the one-touch hanger in FIG.

As shown in FIG. 1, a one-touch hanger includes a receiving device 1 buried in a concrete floor,
And a pipe support 2 mounted therein by elastic deformation.

As the material of the receiving member 1 and the pipe supporting member 2, a plastic material such as polycarbonate, polyacetal or nylon can be used.
In particular, it is preferable to use polycarbonate having excellent heat resistance, moldability and strength.

As shown in FIGS. 1 to 3, the receiving device 1 comprises a cylindrical receiving body 3 and a cap 5 which is screwed to a screw portion 4 formed on the upper portion of the receiving body 3. It is configured. A pair of first nail support pieces 6 are provided at opposing portions of the outer periphery of the receiving body 3, and a second nail support piece is provided at a part of a mounting seat 7 formed at a lower portion of the receiving body 3. 8 are formed. In the inner peripheral portion of the receiving body 3, two recesses 9 separated by a predetermined distance are formed. Notches 10 and 1 formed in the first nail supporting piece 6 and the second nail supporting piece 8.
The notch 10 has a depth of notch 10 smaller than that of the notch 11 so that a nail, which will be described later, is guided by the notches 10 and 11 so as to be easily driven into a V-shape from both sides of the receiving tool 1.

As shown in FIG. 2, the cap 5 has a screw portion 12 screwed to the screw portion 4 formed on an inner periphery thereof, and a grip portion 13 formed therein. The knob 13 is formed in an oval shape so that the nail can be inserted into the cutouts 10 and 11 with the cap 5 attached to the receiving body 3 and the nail can be easily hit.

The pipe support 2 comprises a half-ring-shaped pipe holding portion 14 for holding a pipe, and a pair of leg pieces 15 connected to both ends of the pipe holding portion 14. . The pair of leg pieces 15 has a crescent shape in cross section, and the protrusions 1 which can be engaged with the recesses 9 on the outer periphery.
6 are formed in two stages. The concave portion 9 and the convex portion 16
Although not particularly limited, the engagement is strengthened by forming the wedge shape. As shown in FIG. 4, when the width of the wedge-shaped concave portion 9 is made larger than the width of the wedge-shaped convex portion 16, and when the pipe support 2 is mounted on the receiver 1, the pipe support is The play of the movement of the tool 2 is enabled. Thereby, even if an error occurs in the flatness of the lower surface of the concrete floor of the adjacently buried receiver 1, the posture of the pipe support 2 with respect to the lower surface of the buried concrete floor is corrected so as to be vertical. . The angle α of the concave portion 9 and the convex portion 16 is not particularly limited in the present invention, but is usually 60 °.
８５85 °, preferably 70-75 °.

In this embodiment, the receiving device 1 has two concave portions 9 and the pipe supporting device 2 has two convex portions 16. When the piece 15 is pressed into the receiving member 1 at a reduced interval, first, the convex portion 16 of the pipe support 2 is fitted into the lower concave portion 9 of the receiving member 1. When the pipe support 2 is further pushed into the receiver 1, the convex portions 16 of the pipe support 2 fit into the upper and lower two concave portions 9 of the receiver 1 (see FIG. 5). As described above, in the present embodiment, the pipe support 2 can be attached to the receiver 1 in two stages. However, the present invention is not limited to this, and the pipe support 2 is not limited to this. By forming the convex portion in one step or three or more steps, the pipe support 2 can be attached to the receiver 1 in one step or three steps or more. Further, since the pair of leg pieces 15 have a substantially cylindrical shape in the receiving device 1, they can be freely rotated in the receiving device 1. For this reason, the posture of the pipe support 2 can be changed in any direction regardless of the posture of insertion into the receiver 1. As a result, any bending (angle) pipe can be attached with one touch, so that the working time can be greatly reduced and the working efficiency can be increased. By changing the lower length L of the pair of leg pieces 15 as shown in FIG. 5, the height of the pipe support can be adjusted.

Further, as described above, the pipe support 2 is
2 and 5, on the inner wall surface of the cap 5, for example, a frustoconical bulging portion 17 is formed so as to be located inside the distal end portions of the pair of leg pieces 15. In this case, even when the pipe support 2 supporting the pipe P is attached or swings due to vibration, the distal end of the leg piece 15 hangs on the bulging portion 17, so that the pipe support 2 may come off from the receiving device 1. Absent. In the present embodiment, the pipe support is prevented from coming off by a bulge formed on the inner wall surface of the cap. However, the present invention is not limited to this. For example, as shown in FIG. As described above, the projection can be formed by the projection 21 formed at the lower part of the pair of leg pieces 20.

Note that pipe diameters vary due to manufacturing errors. Therefore, as shown in FIG. 7, the effective inner diameter D of the pipe holding portion 30 is made smaller than the average pipe diameter of the pipe, and an open portion 31 is formed in a part of the pipe holding portion 30. Since the pipe can be sandwiched by being widely opened with the open diameter portion 31 as a fulcrum, the error in the outer diameter dimension can be absorbed and the pipe can be held tight.

Next, an example of using the one-touch hanger of the present invention will be described. First, as shown in FIG. 8, the receivers 1 with the caps 5 screwed to the receiver main bodies 3 are placed on the plywood W by the number necessary to support the pipe, and then the first nail support pieces 6 are placed. Then, the nail N is guided into the notch of the second nail support piece 8 and driven into the plywood W. Thereby, the receiving tool 1 is fixed to the plywood W.

Next, the first nail support piece 6 is broken,
After removal, concrete is poured and the receiving device 1 is buried in the concrete.

After the concrete has hardened, the plywood W
At the same time, the nail N is removed together with the plywood W. When the plywood W is peeled off, the receiving member 1 is made of concrete that has entered the lower portion 40 of the grip portion 13 of the cap 5.
Does not escape from the concrete floor F. In addition, by forming the concave portion 50 in the outer peripheral portion of the receiving body 3, the concrete that has entered the concave portion 50 becomes a resistance, and the receiving device 1 can be prevented from coming off.

Next, as shown in FIG. 9, the pipe support 2 extrapolated to the pipe P is elastically attached to each receiving device 1 with one touch.

In the present embodiment, the receiving member is constituted by the receiving member main body and the cap, but the present invention is not limited to this, and the receiving member main body and the cap are integrally formed. It can also be formed or integrally cut.
