Pipe support member
A pipe support member ( 1 ) includes a restraint member ( 10 ) configured to be fixed to a base metal fitting ( 70 ) by fastening a first bolt (B 1 ) and a first nut (N 1 ) screwed thereto in a state of surrounding an outer peripheral surface of a pipe to hold the pipe; and a nut holding member ( 50 ) configured to be attachably and detachably attached to the restraint member ( 10 ) directly or indirectly such that the first nut (N 1 ) is disposed at an attached position in a state of holding the first nut (N 1 ).
1 . A pipe support member that is connected to a base metal fitting fixed to a structure to support a pipe, comprising:
a restraint member configured to be fixed to the base metal fitting by fastening a first bolt and a first nut screwed to the first bolt in a state of surrounding an outer peripheral surface of the pipe to hold the pipe; and
a nut holding member configured to be attachably and detachably attached to the restraint member directly or indirectly such that the first nut is disposed at an attached position in a state of holding the first nut,
wherein the restraint member comprises a holding portion configured to surround the outer peripheral surface to hold the pipe, base fixing portions configured to extend from the holding portion to face each other and be fixed to the base metal fitting by fastening the first bolt and the first nut, and tightening action portions configured to extend from the holding portion to face each other and apply a tightening force to the holding portion by fastening a second bolt different from the first bolt and a second nut screwed to the second bolt, and
wherein the nut holding member is attachably and detachably attached to the base fixing portions or the tightening action portions directly or indirectly such that the first nut and the second nut are disposed at respective attached positions in a state of holding the second nut in addition to the first nut.
2 . The pipe support member according to claim 1 ,
wherein the nut holding member has a first holding insertion hole that holds the first nut in an insertion state, and
wherein the first holding insertion hole has a shape capable of preventing the first nut from rotating.
3 . The pipe support member according to claim 2 ,
wherein the first holding insertion hole is formed by cutting out a part in a circumferential direction.
4 . The pipe support member according to claim 1 ,
wherein the nut holding member has a second holding insertion hole that holds the second nut in an insertion state, and
wherein the second holding insertion hole has a shape capable of preventing the second nut from rotating.
5 . The pipe support member according to claim 4 ,
wherein the second holding insertion hole is formed by cutting out a part in a circumferential direction.
6 . The pipe support member according to claim 4 ,
wherein the nut holding member has a holding main body portion in which the second holding insertion hole is formed, and holding engagement portions that are provided in the holding main body portion and engaged with the base fixing portions or the tightening action portions from a side opposite to the holding main body portion.
7 . The pipe support member according to claim 1 ,
wherein the holding portion, the base fixing portions, and the tightening action portions are integrally formed, and a notch portion for preventing the tightening force by the fastening of the second bolt from being transmitted to a base fixing portion side is provided between the base fixing portions and the tightening action portions, and
wherein the nut holding member is attached to the base fixing portions directly or indirectly at a position of the notch portion.
8 . The pipe support member according to claim 1 , further comprising:
a fixing auxiliary member configured to temporarily fix the restraint member with respect to the base metal fitting before the fastening by the first bolt, and
wherein the nut holding member is attached to the restraint member via the fixing auxiliary member.
9 . A pipe support member that is connected to a base metal fitting fixed to a structure to support a pipe, comprising:
a restraint member configured to be fixed to the base metal fitting by fastening a first bolt and a first nut screwed to the first bolt in a state of surrounding an outer peripheral surface of the pipe to hold the pipe;
a nut holding member configured to be attachably and detachably attached to the restraint member directly or indirectly such that the first nut is disposed at an attached position in a state of holding the first nut;
a fixing auxiliary member configured to temporarily fix the restraint member with respect to the base metal fitting before the fastening by the first bolt, and
wherein the nut holding member is attached to the restraint member via the fixing auxiliary member.
