Abstract
A bracing apparatus for bracing a flexible pipe extending between a fire sprinkler header pipe and a sprinkler and for holding the sprinkler in a desired location, a flexible piping system having the bracing apparatus, and a method of installing a sprinkler of a sprinkler system having the bracing apparatus. The bracing apparatus has first mounting members that attach to a flexible pipe, and a stiffener bar that extends between the first and second mounting members.
Claims9
A method of installing a sprinkler of a sprinkler system comprising the steps of:
- connecting a first end portion of a flexible pipe to a header pipe,
- attaching a first mounting member to the first end portion of the flexible pipe such that the first mounting member may be rotated around the first end portion of the flexible pipe until it is secured in place on the flexible pipe,
- attaching a second mounting member to a second end portion of the flexible pipe such that the second mounting member may be rotated around the second end portion of the flexible pipe until it is secured in place on the flexible pipe,
- mounting a second end portion of a stiffener bar on the second mounting member such that the stiffener bar may be pivoted around the second mounting member until it is secured in place,
- attaching a first end portion of the stiffener bar to the first mounting member such that the stiffener bar slidingly engages the first mounting member until the stiffener bar is secured to the first mounting member and such that the stiffener bar may pivot around the first mounting member until the stiffener bar is secured to the first mounting member,
- connecting a sprinkler to the second end portion of the flexible pipe,
- moving the sprinkler to a desired location,
- securing the first mounting member to the first end portion of the flexible hose to prevent the first mounting member from rotating around the first end portion of the flexible hose,
- securing the first mounting member to the first end portion of the stiffener bar to prevent the stiffener bar from sliding with respect to the first mounting member and to prevent the stiffener bar from pivoting around the first mounting member, and
- securing the second mounting member to the second end portion of the flexible hose to prevent the second mounting member from rotating around the second end portion of the flexible hose, and securing the second mounting member to the second end portion of the stiffener bar to prevent the stiffener bar from pivoting around the second mounting member.
