As a pipe hanging tool for hanging and fixing a pipe to a shaft member such as a hanging bolt having one end fixed in a ceiling or a wall, or a shank having a modified cross section, for example, at the upper and lower parts of a main body, An upper and lower grip portion that meshes with the screw turned around the outer peripheral surface of the shaft member over at least a half circumference is provided at least at a distance equal to or greater than the diameter of the shaft member, and a hanging pipe is provided on the side surface of the main body over at least a half circumference. A device provided with a tube holding portion for holding the tube is known.

[0003] This type of pipe suspender firstly has a shaft member
The upper and lower grips are fixed by engaging the upper and lower grips with the screws of the shaft member by raising the main body in a state where the upper and lower grips, which are laid down horizontally, face each other. Is pressed and held.

[0004] However, in the above-mentioned pipe suspender, when the fixing position with respect to the shaft member is to be changed in a state where the pipe is mounted, the pipe is temporarily removed from the pipe holding section, and then the main body is turned over to lift the pipe with respect to the shaft member. Also, after the meshing of the lower grip portion is released and the position is changed, the pipe must be mounted after the pipe hanger is mounted again at the desired position of the shaft member according to the above-mentioned operation, and the position changing work is troublesome. have. In particular, since the inside of the ceiling or the inside of the wall where the pipe is suspended is a narrow space, the work of fixing the pipe hanging tool to the shaft member is troublesome, and piping cannot be performed in a short time.

[0005] Further, when it is necessary to provide a pipe with a slight inclination, such as a drain pipe for draining drain water of an air conditioner, the above-mentioned pipe suspender which cannot change the fixed position with respect to the shaft member with the pipe attached. In such a case, it is extremely difficult to provide a pipe with a slight inclination, so that the piping work is troublesome, and there is a possibility that the pipe is piped with a discontinuous inclination.

In order to solve the above-mentioned drawbacks, the present applicant has disclosed in Japanese Patent Application No. 8-160517 a part of the outer peripheral surface of a mounting shaft member to be mounted on a main body provided with a tube holding part. A fixed arm portion having a curved portion and a curved portion of the fixed arm portion substantially coincide with each other, and a pressing arm portion having a curved portion opposed thereto is provided, and a free end portion is provided at an end portion of the fixed arm portion or the pressing arm portion. A locking member that can be locked is provided at the end of the other arm so as to be bendable, and when the mounting shaft member is inserted between the curved portions of the fixed arm portion and the pressing arm portion, the locking member is attached to the outer peripheral surface of the mounting shaft member. An attachment shaft member that can be temporarily fixed by the curved portion of the fixed arm portion and the pressing arm portion that abuts and that reduces the mutual interval between the curved portions when the free end of the locking member is locked to the other arm portion. We have proposed a pipe hanging fixture that can hold a pipe.

However, since this hanging fixture has a structure in which it is inserted from the lower end of the shaft member and is mounted, a large amount of mounting space is required at the lower end side of the shaft member. Since it is difficult to secure a space, piping workability is extremely poor, and it takes time for piping work.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional disadvantages.
It is an object of the present invention to provide a pipe hanger which can be easily attached to a desired position of a shaft member and piped even in a small space, and which can increase the efficiency of piping work.

Another object of the present invention is to provide a pipe hanging tool which can maintain a pipe hanging state even when a part of the pipe is broken due to long-term use.

For example, when the pipe hanger 1 is pressed from the side to a desired height of the shaft member 11 having an axis fixed in the vertical direction on the ceiling surface and having an end fixed to the shaft member 11, the shaft member 11 is fixedly supported. The supporting members 7a, 9a, 17a are supported through the openings of the members 7, 9 and the movable supporting member 17, respectively. At this time, since the support portion 17a is formed so as to support at least a half circumference of the shaft member 11, the shaft member 11 is elastically deformed in the radially expanding direction in accordance with the pressing (press-fitting) on the shaft member 11, and the shaft member 11 is inserted. Thereafter, the screw 17b is returned to its original state by the elastic restoring force and meshes with the screw 11a in the non-energized state. As a result, the pipe hanging device 1 is temporarily fixed to the shaft member 11 in a state in which it can be moved in the vertical direction.

The movable supporting member connected to the operating portion 19, with the base end end surface of the biasing member 21 positioned on the upper surface of the mounting portion 13, 15 and the free end engaged with the engaging recess 19 a of the operating portion 19. The elastic member 17 is elastically deformed in a direction in which the diameter of the support portion 17a is reduced, so that the screw portion 17b is firmly engaged with the screw 11a of the shaft member 11. At this time, the projections 21a and 21b provided at the base end of the urging member 21 are engaged with the engaging recesses 13a and 15a, respectively. Regulates escape.

When the pipe 25 is press-fitted into the pipe holding member 23 of the pipe hanging device 1 fixed to the shaft member 11 by the above-described operation via the insertion opening 23a, the pipe holding member 23 is pressed with the press-fitting. After the tube 25 is elastically deformed in the diameter-enlarging direction and the tube 25 is inserted, the tube 25 is clamped with its elastic recovery.

Then, the strength of the synthetic resin of the pipe hanger 1 decreases with the passage of time, and the mounting portions 13 and 15 and the urging member 21 are reduced.
Even if the hinge portion is cut off, the projections 21a and 21b of the biasing member 21 engage with the engaging recesses 13a and 15a, and the free end of the biasing member 21 engages with the engaging recess 19a. Therefore, the urging member 21 prevents the vinegar from slipping out of the mounting portions 13 and 15 and the operating portion 19 to maintain the elastic deformation state of the movable support member 17, and to fix the fixed state of the pipe hanging tool 1 to the shaft member 11.
