DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe support which is fixed to anchor bolts on a ceiling or the like of a building to enable piping to the ceiling or the like.

[0002]

2. Description of the Related Art Conventionally, in such a pipe support,
For example, as disclosed in Japanese Utility Model Laid-Open Publication No. 4-105281, a holding body fixed to a predetermined position of an anchor bolt and a pipe support for supporting a pipe, the holding body has a pair of locking pieces opposed to a vertical wall portion. The locking piece is provided with an anchor bolt insertion hole having a thin engagement portion that engages with the screw portion of the anchor bolt, and the vertical wall portion has a thin engagement hole of the anchor bolt insertion hole. A plate spring for urging and pressing the joint portion toward the screw portion side of the anchor bolt is formed, and one end of the pipe support is pivotally connected to the holding body so as to be rotatable, and It can be seen that the other end has a cantilever-like elasticity and is configured to be openably and closably engaged with the holder. Then, the pipe support is fixed to the anchor bolt in a state where the pipe support is removed from the holder, and once the pipe is placed on the pipe support, the pipe support of each pipe support is removed. It was set on the holder and the piping was installed. Further, the engagement structure of the other end side of the holding body and the pipe support is provided with a claw projecting in a window formed in the holding body, and formed on the pipe support.
A fitting hole is formed in a hook portion inserted into the window of the holding body, and a claw is fitted in the fitting hole, whereby the pipe support is set on the holding body.

[0003]

However, in the pipe support described above, the pipe is supported by a pipe support formed by bending a band plate into an appropriate shape. Side) is connected to the holder in a non-separable state, the other end (upper end side) is detachable from the holder, and the hooking part on the pipe support side has the upper edge side of the window on the holder side. In particular, when a large diameter and heavy pipe is installed, the pipe support is deformed so as to be entirely lowered. As a result, the other end (upper end) of the pipe support is Since it is inclined upward, the claw portion of the window portion is likely to come off from the fitting hole of the hook portion, and the pipe support is likely to come off from the holder. Further, in addition to the above-mentioned state, since the pipe is positioned laterally with respect to the anchor bolt, the entire anchor bolt and the root may be gradually bent, and the other end (upper end side) of the pipe support is inclined. Becomes even larger,
The pipe support will be more easily detached from the holder. The need to perform pipe installation work in such a state has caused the following problems to be solved. (1) Although the original installation position of the pipe is higher than the temporary installation position, all the pipe supports cannot be set at the same time, and the work is individually performed. Since the load acting on the pipe support is biased or an external force is applied to the pipe during the setting process, an excessive load is applied to the pipe support in the already set pipe support, and it exceeds the allowable range And the hook portion is lowered, and the claw portion is completely disengaged from the fitting hole, so that the pipe support is separated from the holder, and there is a risk that the pipe may fall off. (2) Even if vibrations and impacts when a fluid, especially a high-pressure fluid passes through the pipe after installation, act on the pipe support, the pipe and the surrounding facilities will come off in the same manner as above, and the piping facility and its surrounding facilities will be damaged. There is a danger of doing it.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems (1) and (2), and has a claw projecting into a window formed in a holder and a pipe support. A hook is formed at the other end of the holding member, which is to be inserted into the window of the holding body. A fitting hole for the claw is formed, and a side face on the anchor bolt side of the holding body is provided with a pull-out preventing plate having flexibility. At the same time, by positioning the upper edge of the pull-out prevention plate immediately below the hook, the hook of the deformed pipe support does not fall,
The above object is achieved by preventing the claw from coming off the fitting hole.

Next, the operation of the pipe support according to the present invention will be described. When the pipe (not shown) is set on the pipe support 22 and the pipe support 28 is deformed due to the weight of the pipe, the hook 31 is connected to the upper edge of the upper window 26 and the lower edge of the lower window 26. Because it is sandwiched between the pull-out prevention plates 40, and because the hooking portion 31 is supported by the upper edge 41 of the pull-out prevention plate 40, the hooking portion 31 does not lower even when an external force acts. The claw portion 25 does not come off from the fitting hole 30.

When the pipe support 28 is set, when the hook 31 of the pipe support 28 is inserted into the window 26 of the holder 1, the tip of the hook 31 is prevented from coming off. The hooking portion 31 abuts on the upper end side of the window 40, and then the stopper plate 40 bends and deforms, and the hook portion 31 of the window portion 26 fits into the fitting hole 30 of the hooking portion 31. At the same time, the stopper plate 40 is opened and returns to the original position, so that the pipe support 28 does not come off the holder 1. Also, when removing the pipe support 28, the finger of the hand holding the holding body 1 is forcibly bent along with the protruding piece 44 of the pull-out preventing plate 40, and then the side on which the pipe support 28 is gripped. With this hand, the upper side (hook 31) of the pipe support 28 is pushed down to release the locked state of the fitting hole 30 and the claw 25. In addition, piping support
When the anchor 28 is fixed to the anchor bolt 6, the pipe support 28 can be detached from the holder 1 with one hand. For example, after the pull-out preventing plate 40 is bent with the thumb, the upper side of the pipe support 28 is (Hook 31) is pushed down to release the locked state of the fitting hole 30 and the claw 25.

In the pipe support 22, a locking piece 2 of the holder 1 is attached to an anchor bolt 6 driven into a ceiling or the like.
