Appeal No. 1997-1451
Application 08/145,974
The subject matter on appeal relates to a corrosion-
resistant structural member comprising first and second
lengths of reinforcing rod physically connected with a joint,
wherein the joint and the corrodible surfaces of the rods near
the joint are covered with an open-ended sleeve. The inner
layer of the sleeve comprises a thermoplastic polymer for
softening and liquefying when heat is applied, and an outer
layer of the sleeve comprises a heat-shrinkable polymer for
shrinking when heat is applied. As a consequence of this heat
application, the resulting liquefied thermoplastic polymer
coats the corrodible surfaces and the joint and exudes from
open ends of the sleeve thereby forming a bead and acting as
barrier to corrosion-causing elements. Further details of
this appealed subject matter are set forth in representative
independent claim 1 which reads as follows:
1. A corrosion-resistant structural member comprising:
a first length of reinforcing rod having an anticorrosion
coating and having a connecting end with a corrodible surface
formed by removal of the anti-corrosion coating at the
connecting end;
a second length of reinforcing rod having an
anticorrosion coating and having a connecting end with a
corrodible surface formed by removal of the anti-corrosion
coating at the connecting end;
