Abstract
In order to provide passive fire protection for a member, casing portions that are physically discrete from each other and from the member are made by injection molding of fluid fire-resistant material (which may be intumescent), and allowing the material to cure. The inner surfaces of the casing portions are complementary in shape to a portion of the outer surface of the member. The casing portions collectively form a casing that surrounds the outer surface of the member, with their inner surfaces abutting against the outer surface of the member. The casing portions are secured to the member by a removable strap or collar, an adhesive, or both.
Claims14
A method for providing passive fire protection for a member, the method comprising the steps of:
- (a) providing a plurality of casing portions physically discrete from each other and from the member, wherein the entirety of the structure that makes up the casing portions comprises a fire-resistant intumescent epoxy material which is cured, and wherein each of the casing portions comprises an inner surface for abutting against a portion of an outer surface of the member;
- and
- (b) securing the casing portions to the member, with the inner surfaces of the casing portions abutting against the outer surface of the member, and the casing portions abutting each other to collectively form an elongated casing surrounding the outer surface of the member, wherein the outer surface, of the member, has a cross-sectional shape, the elongated casing comprises a respective inner surface having a shape complementary to the cross-sectional shape;
- and wherein the member has a length dimension, and the elongated casing has a length at least equal to the length dimension.
