Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bolt planted on a wall or a beam for accommodating a cable (electricity or signal line) or for supplying various fluids such as water, oil, air, and refrigerant for an air conditioner. The present invention relates to a pipe suspender for fixing a pipe to be distributed.

[0002]

SUMMARY OF THE INVENTION The applicant of the present invention has disclosed, for example, in Japanese Patent Application No. 8-355083, a structure in which a main body is provided with a shaft adjacent to a fixed support member for supporting the outer peripheral surface of the shaft member at upper and lower portions thereof. A pressing support member for supporting the outer peripheral surface of the member is provided, and a tube holding member for holding the outer peripheral surface of the tube at least over a half circumference is provided on the main body opposite to the fixed supporting member and the pressing supporting member, and the fixed supporting member is pressed. In a pipe hanger provided with an urging member for elastically deforming the supporting member to pinch the shaft member, the fixing member extends in a horizontal direction orthogonal to the axis of the shaft member with respect to the upper fixed supporting member or the urging member. A tube pressing member having an engagement portion engaging with one or both of the support member and the body portion and a tube contact portion contacting the upper outer peripheral surface of the held tube is provided in a bendable manner. Retained tube The tube pressing member on the outer peripheral surface upper proposed contactable to the tube hanger.

[0003] In this type of pipe suspender, a screw substantially matching the screw turned on the outer peripheral surface of the bolt is formed on the inner peripheral surface of the fixed support member and the pressing support member for at least half a circumference, and both are attached at the time of mounting. Although fixed by meshing, the outer diameter and thread pitch of some bolts were not uniform. That is, M10 bolts (outer diameter: 10 mm, screw pitch: 1.5 mm) are generally used as bolts for suspending pipes, but other than this, W3 / 8 bolts (outer diameter:
9.525 mm, screw pitch: 1.5875 mm).

[0004] For this reason, when a pipe hanger is formed by matching the screws of the fixed support member and the pressing support member with the M10 bolt and mounting it on the W3 / 8 bolt, the meshing between the screws becomes incomplete and the screw becomes incomplete. Due to the accumulation of the pitch difference, the screw threads come into contact with each other, and the fixed supporting member and the pressing supporting member are greatly elastically deformed. As a result, the pipe could not be reliably suspended from the bolt for a long time.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional drawbacks, and an object of the present invention is to securely fix pipes having different outer diameters and screw pitches to connect pipes. An object of the present invention is to provide a pipe hanging tool that can be hung.

[0006]

SUMMARY OF THE INVENTION For this reason, the present invention provides a main body provided with a pipe supporting portion on one side, the inner peripheral surface supporting the outer periphery of the bolt for at least half a circumference, and the inner peripheral surface of the bolt being turned around the outer peripheral surface of the bolt. A pipe support provided with a pressing member that presses the outer periphery of the bolt held by the bolt support portion and the bolt support portion on which the engagement screw substantially corresponding to the set screw is formed on the side opposite to the bolt support portion; The engaging screw of the bolt supporting portion is matched with the inner diameter and the screw pitch which mesh with the screw of the larger outer diameter bolt and the least common multiple of the screw pitch of each bolt among the bolts having different outer diameters and screw pitches to be attached. It is characterized in that it is formed at a plurality of places at intervals.
