Abstract
A hanger and support system for suspending a tubular body from an overhead support is disclosed. The support takes the form of a thick-walled plastic pipe, suitably PVC, with two end caps adhesively joined thereto. An upper end cap is secured to an anchor in the overhead support by means of a bolt extending through a hole in the closed cap end and is adhesively joined to a pipe end. A second end cap at the other pipe end likewise is provided with a downwardly extending bolt arranged for attachment to a hanger and that second end cap is adhesively joined to the lower pipe end. The hanger is in the form of a generally circular band having overlapping superposed ends with a hole drilled therethrough for attachment to the downwardly extending bolt.
Claims16
A pipe support and hanger system for use in corrosive environments comprising:
- a cylindrical support member comprising a heavy-walled plastic pipe;
- a first cap member, said cap member comprising a cylinder having one closed end, the inside diameter of said cylinder being sized to snugly fit over a first end of said plastic pipe and adhesively joined thereto;
- first attachment means cooperating with said first cap member to affix said cap member to an overhead support;
- a second cap member, said cap member comprising a cylinder having one closed end, the inside diameter of said cylinder being sized to fit over the other end of said plastic pipe and adhesively joined thereto;
- a hanger member arranged to cradle and support a pipe or duct at a fixed elevation relative to the lower end of said plastic pipe;
- and
- second attachment means arranged to fasten said second cap member to said hanger member.
A method for making a pipe hanger for use in corrosive environments comprising:
- cutting a heavy-walled PVC plastic pipe to form a right cylinder having a height less than the pipe diameter, said PVC pipe having residual stresses from its manufacture;
- making a cut completely through the wall of said cylinder, said cut being generally parallel to the cylinder axis to thereby form a circular band having two band ends;
- allowing said residual stresses to arrange said band ends in an overlapping superposed attitude;
- and
- drilling a hole through said overlapped superposed band ends, said hole sized to allow passage of fastener means for connection of said hanger to a support member.
A method for making a pipe support and hanger system comprising;
- cutting a cylindrical member to a length needed to maintain a tubular body at a desired elevation below an overhead support structure;
- arranging one end of said cylindrical member for attachment to said overhead support structure;
- arranging the other end of said cylindrical member for connection to a hanger;
- making said hanger from a heavy-walled PVC plastic pipe by cutting said pipe to form a right cylinder having a height less than the pipe diameter and thereafter making a cut completely through the wall of said right cylinder, said cut being generally parallel to the cylinder axis to thereby form a circular band having two band ends, allowing stresses residing in said pipe to arrange said band ends in an overlapping superposed attitude, and drilling a hole through said overlapped superposed band ends;
- and
- connecting said hanger to said other end of said cylindrical member using fastener means passing through said hole.
A method for suspending a tubular body from an overhead structure comprising:
- mounting an anchor on an overhead structural member from which said tubular body is to be suspended, said anchor arranged to threadably accept a bolt;
- inserting the threaded shank of a bolt through a centered hole in the closed end of a first cap member, said first cap member comprising a cylinder having one open end and one closed end, and securing said cap member to said anchor by means of said bolt;
- inserting one end of a pipe into the open end of said first cap member, the outside diameter of said pipe selected to provide a snug fit with the inside of said member, and adhesively fastening said pipe to said cap member;
- inserting the threaded shank of a bolt through a centered hole in the closed end of a second cap member, said second cap member comprising a cylinder having one open end and one closed end, and securing said bolt to said second cap member by means of a nut, the threaded shank of said bolt extending beyond said nut;
- mounting said second cap member on the other end of said pipe, the inside diameter of said second cap member being sized to provide a snug fit about the outside of said pipe, and adhesively fastening said pipe to said second cap member;
- and
- mounting a hanger member onto the threaded shank portion of said bolt extending beyond said nut and securing said hanger member to said bolt by means of a second nut, said hanger member comprising a band of generally circular shape and having an aperture for insertion of said bolt shank therethrough.
