Abstract
A device for resisting movement of a pipe suspended by a pipe hanger includes a base and a pair of arms extending from the base. A recess is formed in each of the arms for receiving a portion of a pipe hanger. A projection extends from each arm. The device fits between a suspended pipe and the hanger. Contact between the arms and projections of the device on the one hand and a portion of the pipe hanger on the other hand resists movement of the pipe. Contact between the arms and a portion of the pipe hanger resists movement of the device with respect to the pipe hanger.
Claims48
A device for resisting movement of a pipe relative to a pipe hanger having a loop for receiving the pipe and a nut located at least partially within the loop, the device including:
- a base;
- first and second arms extending upward from the base, each of the arms having a first end connected to the base and a second end;
- an open space between the second end of the first arm and the second end of the second arm;
- and
- a projection extending upwardly at an angle from the first arm toward the second arm and having a free end spaced away from the second arm for contacting the portion of the nut within the loop to resist movement of the pipe relative to the loop in at least one direction.
A device for resisting movement of a pipe relative to a pipe hanger having a loop for receiving the pipe and a nut located at least partially within the loop, the device including:
- a base;
- first and second arms extending upward from the base, each of the arms having a first end connected to the base and a second end;
- an open space between the second end of the first arm and the second end of the second arm;
- a projection extending from the first arm for contacting the portion of the nut within the loop to resist movement of the pipe relative to the loop in at least one direction, and wherein at least one of the arms includes a recess for receiving a portion of the loop.
A device for resisting movement of a pipe relative to a pipe hanger having a loop for receiving the pipe, the device including:
- a base;
- first and second arms extending upward from the base, each of the arms having a first end connected to the base and a second end, the first arm contacting a portion of the loop to resist movement of the pipe relative to the loop in at least one direction;
- an open space between the second end of the first arm and the second end of the second arm, and further including a recess in at least one of the arms for receiving a portion of the loop.
The device according the 22, wherein the first arm contacts the interior surface of the loop.
A device for resisting movement of a pipe relative to a pipe hanger having a loop for receiving the pipe, the device including:
- a base;
- first and second arms extending upward from the base, each of the arms having a first end connected to the base and a second end, the first arm contacting a portion of the loop to resist movement of the pipe relative to the loop in at least one direction;
- an open space between the second end of the first arm and the second end of the second arm, and wherein the first arm contacts the exterior surface of the loop.
The device according to clam 33, wherein the first projection extends from one of the arms.
A device for resisting movement of a pipe in a pipe hanger having a loop in which the pipe rests and a nut extending into the loop, the device including:
- a base;
- a first arm extending from the base and contacting an interior surface of the loop;
- a second arm extending from the base and contacting an interior surface of the loop;
- a recess in the first arm for receiving a portion of the loop;
- a recess in the second arm for receiving a portion of the loop;
- a first projection extending from the first arm and contacting a portion of the nut within the loop;
- and
- a second projection extending from the second arm and contacting a portion of the nut within the loop.
A method of securing a pipe in a pipe hanger comprising the steps of forming a strap loop and suspending a pipe in the bottom of the loop, and suspending the upper portion of the loop from an overhead structure, forming a U-shape restrainer having upwardly extending spring legs, compressing the legs toward each other and inserting the restrainer into the upper portion of the loop above the pipe, and releasing the legs so that the legs engage the strap loop while the bottom of the restrainer seats on the pipe securing the pipe in the loop against movement.
