Abstract
Abstract Insulating support members are secured to one another in an optimized manner to resist shear forces, tensile forces, compression forces and bending moments tending to separate the members, by means of an insulating dowel extending into holes in both members and held in place by a tension member of glass roving impregnated with curable resin.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
84 words
A heavy-duty connection for insulated support members, comprising: first and second insulating members having first and second portions disposed adjacent one another, said portions defining first and second coaxial holes respectively; an insulating dowel member of high shear strength tightly disposed in said holes; and a first tension tie comprising strands of high tensile strength impregnated with curable resin wound under tension about said adjacent portions and also arranged to retain said dowel in said holes, the resin being cured to a rigid state.
Claim 2
Dependent Claim
84 words
A heavy-duty connection for insulated support members, comprising: first and second insulating members having first and second portions disposed adjacent one another, said portions defining first and second coaxial holes respectively; an insulating dowel member of high shear strength tightly disposed in said holes; and a first tension tie comprising strands of high tensile strength impregnated with curable resin wound under tension about said adjacent portions and also arranged to retain said dowel in said holes, the resin being cured to a rigid state.
Claim 3
Dependent Claim
39 words
The combination according to claim 1 including an insulated spacer having a hole therethrough aligned with the first and second holes and tightly disposed between said first and second portions of the insulated members with said dowel passing therethrough.
Claim 4
Dependent Claim
41 words
The combination according to claim 2 further including a second tie of resin impregnated strands passing around said first tie in the plane of said spacer and between the first and second portions, the resin being cured to a rigid state.
Claim 5
Dependent Claim
40 words
The combination according to claim 1, wherein said dowel has at least one end protruding from the first member hole on the side opposite the second member, said first tie passing about the protruding end to hold it in position.
Claim 6
Dependent Claim
42 words
The combination according to claim 1, wherein the first member hole extends completely therethrough, and wherein said dowel has an end disposed within said hole, the first tie being wound so as to cover the hole and retain the dowel in place.
