Abstract
A fire resisting system for passing at least one cable, tube or the like through an opening in a wall in a liquid- and gastight manner, the system including fire resisting member, which can at least partially be provided in the opening, and which can at least partially be provided around the cables, tubes or the like to be passed through the opening.
Claims18
A fire resisting system comprising a wall with an opening in the wall, at least one elongated member extending through said opening in a liquid ad gastight manner, and fire resisting means at least partially disposed in said opening and at least partially disposed around one of said at least one member, said fire resisting means being substantially formed in the shape of a first sleeve means placed around said at least one member, and said system further includes fire resisting filling means defined by at least one additional sleeve means, empty of any elongated members, positioned in at least part of the remaining space in the opening and extending side by side with said first sleeve mans of the fire resisting means.
A fire resistant system comprising a wall unit with an opening in the wall unit;
- and fire resisting means including a plurality of sleeve means, each said sleeve means extending substantially through said opening and each having a longitudinal axis, wherein the longitudinal axes of said plurality of sleeve means are spaced apart and in side by side relation to one another;
- said sleeve means being constituted of material which expands upon heating due to fire to cause said material to expand and close off the sleeve means and opening against the passage of air and fire.
A fire resisting system comprising:
- a) a wall having an opening extending therethrough and at least one cable extending through said opening;
- b) first fire resisting sleeve means defined by a separate sleeve disposed around each cable and extending at least partially in said opening;
- and
- c) a plurality of additional sleeve means, defined by at least one additional sleeve, empty of any cables, extending in the same direction as the first mentioned sleeve means and filling any remaining space in said opening and extending side by side with said first mentioned sleeve means.
A method for passing at least one cable trough an opening in a wall in a liquid and gastight manner comprising the steps of:
- a) passing said cables through said opening;
- b) placing first heat resisting sleeve means over the portion of each of said cables disposed in said opening;
- and
- c) filling any remaining space in said opening not taken up by said cables and said first sleeve means with additional heat resisting sleeve means, empty of any cables, extending in the same direction as and side by side with the first sleeve means.
