Abstract

Abstract A fire resistant seal which at least partially surrounds a member, e.g. a pipe (16), passing through a fireproof building dividing structure, e.g. a floor (14). The seal comprises an adhesive fire-resistant moulding compound (22), spanning the opening between the member (16) and the structure (14) at about the plane of at least one surface of the structure (14). An infill of ceramic fibres (24) is provided in the interstices between the member (16) and structure (14). A layer of adhesive cement (26) may cover the fibres (24). A method of forming such a seal comprises applying afire resistant adhesive cement to span the opening between the member (16) and structure (14) and inserting ceramic fibres (24) between the member (16) and the opening forming the interstice between the member and the inner surface of the hole.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 57 words
A fire-resistant seal at least partially surrounding a member passing through a fireproof building dividing structure comprising an adhesive fire-resistant moulding compound spanning the opening between said member and said dividing structure at about the plane of at least one surface of said structure and ceramic fibre filling the interstices between said member and said dividing structure.
Claim 2
Dependent Claim 57 words
A fire-resistant seal at least partially surrounding a member passing through a fireproof building dividing structure comprising an adhesive fire-resistant moulding compound spanning the opening between said member and said dividing structure at about the plane of at least one surface of said structure and ceramic fibre filling the interstices between said member and said dividing structure.
Claim 3
Dependent Claim 18 words
A seal as claimed in claim 1, wherein said dividing structure is a cement wall, ceiling or floor.
Claim 4
Dependent Claim 20 words
A seal as claimed in claim 1 or 2 wherein said fire-resistant moulding compound comprises ceramic fibre and colloidal silica.
Claim 5
Dependent Claim 21 words
A seal as claimed in claim 3 wherein said fire-resistant moulding compound further comprises a solid acrylic polymer adhesion enhancing agent.
Claim 6
Dependent Claim 15 words
A seal as claimed in claim 4 wherein said fire-resistant cement further comprises aluminium trihydrate.
Claim 7
Dependent Claim 28 words
A seal as claimed in any one of claims 1 to 5, wherein said fire-resistant cement comprises ceramic fibre, colloidal silica, a solid acrylic polymer and aluminium trihydrate.
Claim 8
Dependent Claim 21 words
A seal as claimed in any one of claims 1 to 6, wherein said fire-resistant moulding compound comprises an endothermic material.
Claim 9
Dependent Claim 18 words
A seal as claimed in any one of claims 1 to 7 wherein said member is a pipe.
Claim 10
Independent Claim 71 words
A method of forming a fire-resistant seal at least partially surrounding a member passing through a fireproof building dividing structure comprising applying a fire-resistant adhesive cement to span the opening between said member and the first surface cf said building dividing structure, inserting bulk ceramic fibre into the opening forming the interstice between the member and the inner surface of the hole in the dividing structure through which the member passes.
Claim 11
Independent Claim 71 words
A method of forming a fire-resistant seal at least partially surrounding a member passing through a fireproof building dividing structure comprising applying a fire-resistant adhesive cement to span the opening between said member and the first surface cf said building dividing structure, inserting bulk ceramic fibre into the opening forming the interstice between the member and the inner surface of the hole in the dividing structure through which the member passes.
Claim 12
Dependent Claim 38 words
A method as claimed in claim 9 wherein the method further comprises covering the ceramic fibre insulating material with a second fire-resistant cement seal that is in the general plane of the second surface of the dividing structure.
Claim 13
Dependent Claim 36 words
A method as claimed in claim 10 wherein said first adhesive cement seal is generally in the plane of the first surface of the dividing structure and the said second seal is on the opposite surface.
Claim 14
Independent Claim 29 words
A method as claimed in any one of claims 9 to 11 wherein said adhesive sealing material comprises ceramic fibre, colloidal silica and a solid acrylic polymer adhesive-enhancing agent.
Claim 15
Dependent Claim 15 words
A method as claimed in claim 12, wherein said fire-resistant adhesive further comprises aluminium trihydrate.
Claim 16
Independent Claim 18 words

Claim 18
Independent Claim 29 words
A method as claimed in any one of claims 9 to 15 wherein said adhesive sealing material comprises ceramic fibre, colloidal silica, a solid acrylic polymer and aluminium trihydrate.
Claim 19
Independent Claim 19 words
A method as claimed in any one of claims 9 to 16, wherein said member is an electrical conduit.
Claim 20
Independent Claim 20 words
