BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe support for hanging and supporting pipes such as air-conditioning pipes and electric pipes from a ceiling or a wall. More specifically, the present invention relates to a pipe support for receiving and supporting pipes. The present invention relates to a pipe support in which a hook for suspending the receiving portion over a fixed portion is connected to a portion.

[0002]

2. Description of the Related Art In the case of performing a piping operation using the above-described piping support, generally, a hanging metal fitting is previously attached as a fixing portion to a plurality of hanging bolts or the like installed along a construction route of the piping. At the same time, the hooks of the pipe supports are straddled on each fixed part, and the pipe is laid between the receiving parts suspended from each fixed part, and then the pipe support is fixed together with the cover for preventing the pipe from falling It is fixed to the part via a bolt. Conventionally, in such a pipe support, there is known a hook in which a hook is formed by bending a flat plate, and the hook can be hooked over a fixed portion.

[0003]

However, the conventional pipe support described above merely hooks the hook on the fixing part, and therefore receives the pipe until it is permanently fixed to the fixing part by bolts. When the work is put on the part, the hook easily comes off the fixed part due to the contact of the pipe or the hand of the operator, and the pipe support is likely to drop. This type of plumbing work is usually performed in high places near the ceiling, so if the plumbing support falls, it is dangerous for those working below, It was necessary to go for the support tool, resulting in a decrease in work efficiency. In view of the above circumstances, an object of the present invention is to provide a pipe support which is not likely to come off from a fixed portion before being completely fixed to the fixed portion.

[0004]

The characteristic structure of the pipe support according to the present invention is as follows.
A pipe support body in which hooks for suspending the receiving portion over the fixing portion are provided, and the locking piece restored to the locked portion of the fixing portion is locked. A locking device made of a leaf spring for preventing the hook from being detached and temporarily fixing the hook,
Formed separately from the hook and attached to the hook
And for fully fixing the hook to the fixing portion.
A screw fixing portion is provided on the locking tool .

[0005]

[Operation] In other words, the pipe support is fully fixed to the solid portion via bolts or the like by locking the locking member to the locked portion of the fixing portion with the hook straddling the fixing portion. even in the absence, prevents the hook from the fixing portion is detached by the provisional
It can be fixed to prevent the pipe support from coming off. Also,
Since the locking member is made of a leaf spring, a desired elastic deformation can be obtained even when the thickness is reduced, so that a locking member having a locking piece having a desired projection height can be formed by a thin leaf spring. For this reason,
Since the thickness of the hook can be reduced, and when the hook is inserted, the protrusion of the hook decreases due to the elastic deformation of the hook. For example, the hook is inserted into the insertion slot (slit, etc.) and used. If you do not need to change the width, just attach to the hook in the conventional equipment,
The hook can be prevented from detaching from the fixing portion. Further, since the locking member is formed as a member separate from the hook, the main body of the pipe supporting member including the hook can be made of a material having a high supporting strength which is convenient for pipe support and the like. On the other hand, since the screw fixing portion is provided on the locking tool,
After the above temporary fixation, use a bolt or the like to attach the hook to the fixing portion.
The book can be fixed. At this time, the locking device is
Because it is formed by a leaf spring that is a separate member from the
Can be easily formed by sheet metal processing, and the elasticity of the leaf spring can be restored.
It is possible to form a screw hole to fix the screw using the original force
It is possible. In addition, the locking tool provided with the screw fixing part is a plate
Because it is made of spring, it is bent by tightening bolts etc.
And the resulting elastic stress plays the same role as the spring washer
Therefore, loosening of bolts and the like can be suppressed.

[0006]

[Effects of the Invention] As a result, in a simple method of attaching a lock to a hook of a conventional facility, even if a pipe or an operator's hand hits the pipe support before the pipe support is fully fixed, the pipe support is removed from the fixing portion. Because it is possible to avoid the situation of falling off and dropping, there is no danger to people working below in piping work that is often performed at high places, and the piping work is interrupted to get the dropped pipe support The pipe support was able to proceed smoothly and safely without any pipe work.
Then, using the locking tool, the pipe support is
This can be fixed, but the screw fixing part for that is easy to process.
Yes, and it is possible to reduce the looseness of the bolts and the like after the permanent fixing.
