Abstract
A structural reinforcement for a hollow member comprising a rigid reinforcing member having a shape that substantially conforms to the cross section of the section of the hollow member to be reinforced with an expandable adhesive material over at least a portion of the surface of the rigid reinforcing member sufficient to bond the reinforcing member to at least two nonparallel internal surfaces of the structure.
Claims24
A structural reinforcement for a hollow member comprising a rigid reinforcing member having lugs for enabling it to stand away from the interior walls of the sections of the structural member;
- a shape that substantially conforms to the cross section of the section of the hollow member with an expandable adhesive material over at least a portion of the surface of said rigid reinforcing member sufficient to bond the reinforcing member to at least two non parallel internal surfaces of the hollow member.
A reinforced hollow member containing a structural reinforcing member bonded to at least two non-parallel internal surfaces of the hollow member by an expanded adhesive material.
A structural reinforcement for reinforcing a hollow structural member comprising:
- a structural reinforcing member having an exterior shape conforming substantially to the interior cross section of said hollow structural member, said exterior shape varying along the length of said structural reinforcing member to mirror the variations of said interior cross section;
- unfoamed expansive adhesive material contained between said structural reinforcing member and said hollow structural member, said adhesive material approaches an internal surface of the hollow structural member;
- wherein said unfoamed expansive adhesive material can be activated to both expand and to act as an adhesive when heated;
- wherein said unfoamed expansive adhesive material is dry and not tacky to the touch prior to activation of said material;
- wherein said structural reinforcing member further comprises at least one lug attached to said structural reinforcing member and locating said member within said hollow structural member when said structural reinforcing member is placed within said hollow structural member prior to activation of said material;
- and
- wherein said structural reinforcing member is bonded to said internal surface of said hollow structural member after activation of said material.
