Claim 7

A fire-resistant structural assembly, comprising a structural member having projecting edges and an exposed surface between said edges, a first layer of insulative material disposed over at least a portion of said exposed surface, said first layer having an exterior surface directed away from said exposed surface, a second layer of insulative material disposed over at least a portion of said exterior surface of said first layer, and attachment means for attaching said first and second layers of insulative material to said structural member, said means including an impaling projection for impaling one of said layers and a clamping member separate from said projection, disposed over a portion of an exterior surface of the other of said layers so as to hold said other layer in position.

Claim 8

A fire-resistant structural assembly, comprising a structural member having projecting edges, a first layer of insulative material disposed over at least a portion of the exposed surface of said structural member between said projecting edges, said layer having two opposed exterior surfaces one of which faces said exposed structural member surface, a second layer of insulative material disposed over at least a portion of the other of said opposed surfaces of said first layer, and attachment means for attaching said first and second layers of insulative material to said structural member, said means including an impaling projection for impaling one of said layers and a clamping member separate from said projection, disposed over a portion of an exterior surface of the other of said layers so as to hold said other layer in position.

Claim 9

A fire-resistant structural assembly, comprising a structural member having projecting edges, a first layer of insulative material disposed over at least a portion of the exposed surface of said structural member between said projecting edges, said layer having two opposed exterior surfaces one of which faces said exposed structural member surface, a second layer of insulative material disposed over at least a portion of the other of said opposed surfaces of said first layer, and attachment means for attaching said first and second layers of insulative material to said structural member, said means including an impaling projection for impaling one of said layers and a clamping member separate from said projection, disposed over a portion of an exterior surface of the other of said layers so as to hold said other layer in position.

Claim 10

The assembly as defined in claim 6, wherein said other layer is said first layer and said one layer is said second layer.

Claim 11

The assembly as defined in claim 7, wherein said impaling projection extends generally perpendicular to said other opposed exterior surface, said second layer being impaled on said projection.

Claim 12

The assembly as defined in claim 6, and further including another impaling projection and a third sheet of insulative material impaled over said other projection, said third sheet being angularly disposed about said structural member with respect to said first and second layers.

Claim 13

The assembly as defined in claim 9, wherein said other projection lies generally in the plane of the interface between said first and said second layers.

Claim 14

The assembly as defined in claim 6, wherein a portion of said clamping member extEnds generally parallel to said exposed structural member surface, said first layer being sandwiched between said clamping member and said exposed structural member surface.

Claim 15

The assembly as defined in claim 6, wherein said impaling projection extends generally perpendicular to said other opposed exterior surface, said second layer being impaled on said projection.

Claim 16

A fire-resistant structural assembly, comprising a structural member having exposed surfaces terminating in a plurality of edges, a first layer of insulative material disposed over the exposed surfaces so as to completely surround said member, a second layer of insulative material disposed over at least a portion of said first layer, and attachment means for independently attaching said first and second layers of insulative material to said member, said attachment means including a plurality of clips spaced apart along said edges, each of said clips including an impaling projection for impaling one of said layers and a clamping member separate from said projection, disposed over a portion of an exterior surface of the other of said layers and one of said edges so as to hold said other layer in position, clamped to said structural member.

Claim 17

A fire-resistant structural assembly, comprising a structural member having exposed surfaces terminating in a plurality of edges, a first layer of insulative material disposed over the exposed surfaces so as to completely surround said member, a second layer of insulative material disposed over at least a portion of said first layer, and attachment means for independently attaching said first and second layers of insulative material to said member, said attachment means including a plurality of clips spaced apart along said edges, each of said clips including an impaling projection for impaling one of said layers and a clamping member separate from said projection, disposed over a portion of an exterior surface of the other of said layers and one of said edges so as to hold said other layer in position, clamped to said structural member.
